The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[001] Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a seatbelt assembly of a vehicle.
BACKGROUND OF THE DISCLOSURE
[002] Vehicles such as passenger vehicles and commercial vehicles and the like include restraints in the form of seatbelts, which are intended to be worn by an occupant sitting on the seats of the vehicle. In general, seatbelts are designed to restrain the occupant on the seat in the event of an accident or other abrupt movements or impact of the vehicle. The seatbelt typically includes a shoulder belt intended to be worn across the occupant's torso and a waist belt intended to be worn across the waist.
[003] Further, the seatbelts are latched into a seatbelt buckle assembly, which is rigidly fixed to a seat raiser or a seat frame. In case of an impact or abrupt movement of the vehicle, the seatbelt exerts large and abrupt reaction forces on the torso of the occupant due to inertial force experienced by the occupant. For example, in the case of a frontal impact to the vehicle, the torso may experience a forward force due to inertia. Such a forward force is countered by the seatbelt, which causes heavy reaction forces on the torso. The heavy and abrupt reaction forces on the torso of the occupant may lead to physical damage of the ribs and sternum of the occupant.
[004] Present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.
SUMMARY OF THE DISCLOSURE
[005] One or more shortcomings of the prior art are overcome by an assembly as claimed and additional advantages are provided through the assembly as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.

[006] In one non-limiting embodiment, a seatbelt assembly of a vehicle is disclosed. The seatbelt assembly includes a frame which is associated with a seat in the vehicle. The frame is defined with an elongated slot and a provision that is defined adjacent to the elongated slot. Additionally, the seatbelt assembly includes a seatbelt buckle assembly which is configured to selectively latch a seatbelt. The seatbelt buckle assembly includes a support member that is adapted to extend through the elongated slot for slidably supporting the seatbelt buckle assembly with the frame. Further, the seatbelt assembly includes a locking member which is configured to extend through the provision for locking the seatbelt buckle assembly with the frame. The locking member is configured to prevent sliding of the seatbelt buckle assembly, where the locking member is adapted to shear in response to a force exerted on the seatbelt buckle assembly exceeding a threshold force. The shearing of the locking member allows sliding of the seatbelt buckle assembly along the elongated slot. The configuration of the seatbelt bracket to slide along the elongated slot upon shearing of the locking member prevents heavy and abrupt loading on an occupant during accidents thereby reducing the forces on the thorax of the occupants.
[007] In an embodiment, the elongated slot is defined with a tapered profile to allow gradual sliding displacement of the seatbelt buckle assembly along the elongated slot, thereby preventing sudden and jerky motion of the seatbelt buckle assembly.
[008] In an embodiment, the elongated slot includes a first end being defined with a first diameter and a second end, opposite to the first end being defined with a second diameter. The first diameter is greater than the second diameter to form the tapered profile which aids in gradual displacement of the support member along the elongated slot.
[009] In an embodiment, diameter of the support member is substantially equal to the first diameter of the first end, where the first end is configured to receive the support member.
[010] In an embodiment, the locking member is integrally defined in the seatbelt buckle assembly.
[011] In an embodiment, the support member and the elongated slot are defined with grooves complementing each other for slidably supporting the seatbelt buckle assembly with the frame.

The grooves may create a path for sliding displacement of the support member within the elongated slot.
[012] In another non-limiting embodiment, a vehicle is disclosed. The vehicle includes a cabin and a seat slidably positioned in the cabin. Further, the vehicle includes a seatbelt assembly. The seatbelt assembly includes a frame which is associated with the seat in the vehicle. The frame is defined with an elongated slot and a provision that is defined adjacent to the elongated slot. Additionally, the seatbelt assembly includes a seatbelt buckle assembly which is configured to selectively latch a seatbelt. The seatbelt buckle assembly includes a support member that is adapted to extend through the elongated slot for slidably supporting the seatbelt buckle assembly with the frame. Further, the seatbelt assembly includes a locking member which is configured to extend through the provision for locking the seatbelt buckle assembly with the frame. The locking member is configured to prevent sliding of the seatbelt buckle assembly, where the locking member is adapted to shear in response to a force exerted on the seatbelt buckle assembly exceeding a threshold force. The shearing of the locking member allows sliding of the seatbelt buckle assembly along the elongated slot.
[013] In an embodiment, the frame is configured to slide along with sliding of the seat.
[014] The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.

DETAILED DESCRIPTION
[022] The foregoing has broadly outlined the features and technical advantages of the present disclosure in order that the detailed description of the disclosure that follows may be better understood. Additional features and advantages of the disclosure will be described hereinafter which forms the subject of the claims of the disclosure. It should be appreciated by those skilled in the art that, the conception and specific embodiments disclosed may be readily utilized as a basis for modifying other devices, assemblies, system, methods and processes for carrying out the same purposes of the present disclosure. It should also be realized by those skilled in the art that, such equivalent construction and method do not depart from the scope of the disclosure as set forth in the appended claims. The novel features which are believed to be characteristics of the

disclosure, to its construction and features, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.
[023] In the present document, the word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or implementation of the present subject matter described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
[024] While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will be described in detail below. It should be understood, however that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure.
[025] The terms “comprises”, “comprising”, or any other variations thereof, are intended to cover a non-exclusive inclusions, such that a device or a system or a method that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such device, assembly, system or method. In other words, one or more elements in a device or an assembly or a system or a method proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the device or system or method.
[026] In accordance with various embodiments of the present disclosure, a seatbelt assembly of a vehicle is disclosed. The seatbelt assembly includes a frame which is associated with a seat in the vehicle. The frame is defined with an elongated slot and a provision that is defined adjacent to the elongated slot. Additionally, the seatbelt assembly includes a seatbelt buckle assembly which is configured to selectively latch a seatbelt. The seatbelt buckle assembly includes a support member that is adapted to extend through the elongated slot for slidably supporting the seatbelt buckle assembly with the frame. Further, the seatbelt assembly includes a locking member which

is configured to extend through the provision for locking the seatbelt buckle assembly with the frame. The locking member is configured to prevent sliding of the seatbelt buckle assembly, where the locking member is adapted to shear in response to a force exerted on the seatbelt buckle assembly exceeding a threshold force. The shearing of the locking member allows sliding of the seatbelt buckle assembly along the elongated slot.
[027] The configuration of the seatbelt bracket facilitates the seatbelt bracket to slide along the elongated slot upon shearing of the locking member due to the force exerted on the seatbelt by the occupant to prevent heavy and abrupt loading on the occupant during accidents. That is, the seatbelt assembly reduces backlash forces generated by the seatbelt, thereby reducing physical damage of the occupants.
[028] Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to Figs. 1-5.
[029] Figs. 1 and 2 illustrates a side view of a seatbelt assembly (100) of a vehicle [not shown in Figs]. In an embodiment, the vehicle may be, for example, a passenger vehicle or a commercial vehicle. The vehicle may include a cabin that may be configured to accommodate occupants. Further, the vehicle may include a seat (7) which may be slidably positioned in the cabin [the seat may not be a part of the seatbelt assembly]. In an embodiment, the vehicle may include more than one seat (7) to seat the occupants. Furthermore, the vehicle may include a seatbelt assembly (100) provisioned within the cabin to securely support the occupants on the seat. The seatbelt assembly (100) may include a seatbelt (8) which may be retractably supported in a portion of the cabin [e.g., B pillar or C pillar of the vehicle]. That is, the seatbelt (8) may be retractably displaced from the B pillar or C pillar and may be worn by the occupant while residing on the seat (7). Additionally, the seatbelt assembly (100) may include a frame (1) which may be associated with the seat (7) in the cabin of the vehicle. In an embodiment, the frame (1) may be an integral part of the seat (7) or may be a separate part to which the seat (7) may be coupled. Further, the frame (1) may be positioned on one or more sliders or rails which may facilitate the frame (1) to displace forwards and backwards based on the requirement of the occupant. That is, the frame (1) may be configured

to slide along with sliding of the seat (7). In another embodiment, the frame (1) may be rigidly fixed to the cabin floor.
[030] Further as seen in Fig. 3, the frame (1) may be defined with an elongated slot (2). The elongated slot (2) may include a first end (2a) and a second end (2b) which may be opposite to the first end (2a). The elongated slot (2) may extend in a lengthwise direction of the vehicle and the first end (2a) and second end (2b) may be ends of the elongated slot (2) in the lengthwise direction of the vehicle. The first end (2a) may be defined with a first diameter and the second end (2b) may be defined with a second diameter. In an embodiment, the first diameter may be greater than the second diameter. The first end (2a) of the elongated slot (2) may be defined proximal to a rear portion of the seat (7) and the second end (2b) of the elongated slot (2) may be defined opposite to the first end (2a) towards a front portion of the seat. The difference between the first diameter and the second diameter enables the elongated slot (2) to be defined with a tapered profile.
[031] Referring now to Figs. 1 and 4, the seatbelt assembly (100) may include a seatbelt buckle assembly (3). The seatbelt buckle assembly (3) may include a body (3b) and a buckle (3a). The seatbelt buckle assembly (3) may be configured to latch the seatbelt (8) for securing the occupant on the seat (7) in the cabin of the vehicle. The buckle (3a) of the seatbelt buckle assembly (3) may be configured to receive a tongue of the seatbelt (8) and latch the seatbelt (8). Further, referring to Figs. 2 and 5, the body (3b) of the seatbelt buckle assembly (3) may include a support member (4) which may be adapted to extend through the elongated slot (2) for slidably supporting the seatbelt buckle assembly (3) with the frame (1). In an embodiment, support member (4) positioned within the elongated slot (2) may be subjected to gradual sliding displacement and in-turn gradual displacement of the seatbelt buckle assembly (3) along the elongated slot due to the tapered profile of the elongated slot (2). In an embodiment, the support member (4) may be integrally formed with the body (3b) of the seatbelt buckle assembly (3) or may be an external component which may be received in the body (3b) of the seatbelt buckle assembly (3). As an example, the support member may be a fastener such as a nut and bolt arrangement. In an embodiment, the diameter of the support member (4) may be substantially equal to the first diameter at the first end (2a) of the elongated slot (2), such that the first end (2a) may be configured to receive the support member (4). Here the term substantially, refers to the diameter of the support member (4) being equal to the diameter of the first end (2a) of the elongated slot (2) or may be marginally lesser than the

diameter of the first end (2a) of the elongated slot (2) to slidably support the seatbelt buckle assembly (3) with the frame (1).
[032] As seen in Fig. 5, the seatbelt buckle assembly (3) may include a locking member (5) which may be defined on the body (3b) of the seatbelt buckle assembly (3). The locking member (5) may project from an outer surface of the body (3b). The locking member (5) may be located adjacent to the support member (4). For example, the locking member (5) may be located slightly upwards of the support member (4), such as between the support member (4) and the buckle (3a). The locking member (5) may be rigidly coupled to the seatbelt buckle assembly (3). For example, the locking member (5) may be integrally defined on the seatbelt buckle assembly (3) or may be externally fixed on the seatbelt buckle assembly (3). The locking member (5) may be configured to extend from the outer surface of the body (3b) through a provision (6) which may be defined in the frame (1). In an embodiment, the frame (1) may include a provision (6) which may be defined adjacent to the elongated slot (2). The locking member (5) may be configured to lock the seatbelt buckle assembly (3) with the frame (1) at the first end (2a) and may prevent sliding of the seatbelt buckle assembly (3) within the elongated slot (2).
[033] In an embodiment, the locking member (5) may be adapted to shear in response to a force that may be exerted on the seatbelt buckle assembly (3). In an embodiment, the locking member (5) may be adapted to shear when the force exerted on the seatbelt buckle assembly (3) may exceed a threshold force. The threshold force may correspond to a force exerted on the seatbelt (8) due to an inertial force experienced by the occupant in event of an accident or collision or other abrupt movements of the vehicle. In an embodiment, the locking member (5) may be made of a material which may be configured to shear or break when the force exerted on the locking member (5) exceeds the threshold force. Accordingly, in the case of an accident or an abrupt movement of the vehicle, the locking member (5) may shear.
[034] Upon shearing of the locking member (5), the seatbelt buckle assembly (3) is no longer restrained from sliding along the elongated slot (2). Accordingly, upon the shearing, the seatbelt buckle assembly (3) may be adapted to slide along the tapered elongated slot (2). That is, upon shearing of the locking member (5), the seatbelt buckle assembly (3) may slide from the first end (2a) towards the second end (2b) of the elongated slot (2). Since the diameter of the elongated slot

(2) decreases from the first end (2a) and since the support member (4) has a diameter substantially equal to that of the first end (2a), the support member (4) moves through a region having a size lesser than itself, during the sliding. Thus, the sliding movement of the support member (4), and consequently, the seatbelt buckle assembly (3), is met with resistance from the elongated slot (2), and therefore, results in gradual displacement of the seatbelt buckle assembly (3).
[035] In an embodiment, at least one of the support member (4) and the elongated slot (2) may be defined with grooves [not shown in Figs.] which may complement one another for slidably supporting the seatbelt buckle assembly (3) with the frame (1). For example, both the support member (4) and the elongated slot (2) may be defined with complementing grooves which may come in contact upon positioning the support member (4) within the elongated slot (2) to enable sliding motion of the support member (4) within the elongated slot (2). The grooves may create a path for sliding displacement of the support member (4) within the elongated slot (2).
[036] In an embodiment, the elongated slot (2) and the provision (6) may be defined at a predefined location of the frame (1) such that the seatbelt buckle assembly (3) is supported by the frame (1) in a required position at a side of the seat (7) to receive the seatbelt (8).
[037] In an operational embodiment, as seen in Figs. 1 and 2, the seatbelt buckle assembly (3) may be supported at the first end (2a) of the elongated slot (2) and the seatbelt (8) may be latched in the seatbelt buckle assembly (3). The position of the seatbelt buckle assembly (3) at the first end (2a) may depict normal operating condition of the seatbelt buckle assembly (3), where the seatbelt (8) may be latched to the seatbelt buckle assembly (3) when the occupant is seated on the seat. During impact or abrupt movement of the vehicle, the force exerted on the seatbelt (8) by the occupant due to inertial force, may exceed the threshold force, and the force may be in-turn transferred onto the seatbelt buckle assembly (3). The locking member (5) extending through the provision (6) may shear when the force exerted on the seatbelt buckle assembly (3) exceeds a threshold force. Upon shearing of the locking member (5), and due to force exerting on the seatbelt buckle assembly (3), the seatbelt buckle assembly (3) may slidably displace the seatbelt buckle assembly (3) along the tapered profile of the elongated slot (2). That is, the support member (4) may slide along the elongated slot (2) from the first end (2a) towards the second end (2b). The tapered profile of the elongated slot (2) facilitates gradual sliding of the support member (4)

thereby mitigating sudden jerky movements which in turn dampens the force exerted by the seatbelt (8) on the body of the occupant.
[038] In an embodiment, the sliding displacement of the support member (4) along the tapered profile may result in deformation of the elongated slot (2) resulting in gradual and dampened movement, due to the diameter of the support member (4) being greater than the second diameter of the elongated slot (2) at the second end (2b).
[039] In an embodiment, the configuration of the seatbelt assembly (100) prevents heavy and abrupt loading of the torso of the and the waist of the occupant which results in reducing to physical damage to the occupant. The seatbelt assembly (100) reduces backlash exerted by the seatbelt (8) on the occupant.
[040] It should be noted that in an exemplary embodiment, as seen in the Figs. 1-5 the features, construction, position and connections should not be construed as a limitation as the seatbelt assembly (100) may include any other type of features, construction, position, and connections which may work with other combinations for reducing backlash exerted by the seatbelt on the occupant.
[041] It should be imperative that the reinforcement bracket, the seatbelt assembly and any other elements described in the above detailed description should not be considered as a limitation with respect to the figures. Rather, variation to such system and method should be considered within the scope of the detailed description.
Equivalents:
[042] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[043] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as

“open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

[044] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
[045] While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope.
