Specification

Description:TECHNICAL FIELD

Present disclosure in general, relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to a seat assembly of a vehicle. Further, embodiments of the present disclosure relate to a height adjustable seat assembly for traversing the seat along a horizontal and a vertical direction.

BACKGROUND OF THE INVENTION

Generally, vehicles such as passenger vehicles, commercial vehicles are employed with seating devices for accommodating the passengers. Drivers who drive for longer hours are more prone for health issues due to prolonged seating and absorption of vibrations generated in the vehicles. Further, the drivers who drive for a prolonged period of time every day, are prone to back and spinal cord related problems. Also, it is seen that these drivers are not able to work for many years and seek premature retirement due to the above reasons. It is a similar case for even passenger vehicles, where long duration of drives may become uncomfortable for the passengers seated in the vehicle. Conventionally, various efforts have been made to improve the comfort to the passengers and drivers while travelling in the vehicles.

One of the major ergonomic deficiencies in conventional seats is with regards to their limited adjustability for drivers of larger or smaller postures. Drivers of shorter height generally prefer to be seated at a higher platform from the floor of the vehicle for providing a commanding view of the road ahead while driving the vehicle. Taller drivers prefer to adjust the seat to a lower position to retain the required flexibility in maneuvering their legs to operate the drive pedals or brake pedals of the vehicle. Taller drivers also prefer the seat to be positioned at low heights or closer to the floor of the vehicle to prevent their head from being obstructed by the roof of the vehicle.

Further, conventional seats are often fixed/limited with regards to their ability to be maneuvered along a vertical direction. Drivers of tall height generally prefer the seat to be positioned lower towards the floor of the vehicle. However, drivers of short height generally find it un-comfortable since, their ability to view the pathway ahead is hindered. Consequently, the ability of the driver to maneuver the vehicle through the obstacles/vehicles on the pathway ahead is hampered and the possibilities of accidents increases significantly.

The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional configuration of intake ports.

The extension of the vertical section of the frame (4) may be configured with a provision and the top end of the support rod (20) may be configured to pass through the provision of the extension for accommodating the extension of the frame (4). The frame (4) may further rest on a top surface of the column (13b) of the support structure (13). The height adjustment assembly (100) may further include a first tension member (9) and a second tension member (6). The first tension member (9) and the second tension member (6) may be accommodated by the support structure (13). More particularly, the first tension member (9) and the second tension member (6) may be accommodated by the support rod (8) in the support structure (13). Both of the first tension member (9) and the second tension member (6) may be configured to extend through a first axis (A-A). The second tension member (6) may be configured to be positioned below/beneath the first tension member (9) in the support rod (20). A first stopper (16) may be configured to a substantially top region of the support rod (8). In an embodiment, the top region of the support rod (8) may be defined as the region of the support rod (8) that lies proximal to the region of frame (4) that is accommodated on the column (13b). A top end of the first stopper (16) may be configured to accommodate the extension of the frame (4) whereas, a bottom end of the first stopper (16) may be configured to abut a top end of the first tension member (9). The first stopper (16) may restrict the upward movement of the first tension member (9). Further, a second stopper (17) may be configured to lie between the first tension member (9) and the second tension member (6). The second stopper (17) may be positioned at a substantially central region of the support rod (20). A top end of the second stopper (17) may be configured to abut a bottom end of the first tension member (9). A bottom end of the second stopper (17) may be configured to lie in contact with a shaft (18). The second stopper (17) may be slidably connected to the support rod (20) and the second stopper (17) may be configured to restrict the downward movement of the first tension member (9). The second tension member (6) which is positioned below the first tension member (9) may be configured such that a top end of the second tension member (6) comes in contact with the shaft (18). Further, the height adjustment assembly (100) may also include a third stopper (19). The third stopper (19) may be fixed to a substantially bottom region of the support rod (20). The third stopper (19) may be configured such that a top surface of the third stopper (19) abuts/comes in contact with a bottom end of the second tension member (6). The third stopper (19) may restrict the downward movement of the second tension member (6).

The first tension member (9) and the second tension member (6) may be configured with varying stiffness. The stiffness of the second tension member (6) may be configured to be greater than the stiffness of the first tension member (9). In this preferable and exemplary embodiment, the ratio of stiffness between the first tension member (9) to the second tension member (6) may be 1:3. The second tension member (6) may be three times stiffer than the first tension member (9).

In an embodiment, the configuration of the second tension member (6) to lie below the first tension member (9) must not be considered as a limitation. The second tension member (6) may be positioned to lie above the first tension member (9) in an embodiment.

In this preferable and exemplary embodiment, the first tension member (9) and the second tension member (6) may be helical springs. The first tension member (9) and the second tension member (6) must not be limited to helical springs and any other material or assembly that offers flexible resistance for the accommodation of seat (1) may be configured.

The configuration of the shaft (18) that is positioned between the second stopper (17) and the second tension member (6) is explained below with greater detail. Reference is made to Figure 5a and Figure 5b which illustrate a top view of the shaft (18). The shaft (18) may include at least one connector (18a) [hereinafter referred to as the connector]. The connector (18a) may be defined with a flat surface. In this preferable and exemplary embodiment, the connector (18a) may be defined with a square or rectangular shape based on requirement. The shaft (18) may be aligned with the support structure such that the connector (18a) of the shaft (18) is configured to lie between the second stopper (17) and the second tension member (6). The bottom surface of the second stopper (17) may abut a top surface of the connector (18a) and the top end of the second tension member (6) may abut a bottom surface of the connector (18a). The connector (18a) may also be configured with a locking member (15). The locking member (15) may be a protrusion that is configured to engage and disengage from the slots (14) of the support structure (13). The shaft (18) is configured with the support structure (13) such that the connector (18a) with the locking member (15) lies adjacent to the slots (14) in the support structure (13). Further, support structure (13) may also be defined with a provision for accommodating the shaft (18). The provision may be configured to extend in a direction that is perpendicular to the first axis (A-A) and may extend along a second axis (B-B). The shaft (18) may also be configured with a lever (7) at one of the ends. The lever (7) may be operable by a user and the lever may enable the shaft (18) to rotate along the second axis (B-B). The support structure (13) may be configured with bearings along the regions where the shaft (18) extends through the support structure (13) and the bearings may facilitate the rotation of the shaft (18). The shaft (18) may be operable between a first position and a second position. The locking members (15) which protrude from the connectors (18a) of the shaft (18) may also rotate between the first position and the second position as the shaft (18) is rotated by the lever. The first position of the locking member (15) may herein be considered as the engaged position where the locking member (15) is accommodated or housed within one of the plurality of slots (14) in the support structure (13). The second position of the locking member (15) may herein be considered as a disengaged position of the locking member (15). As the shaft (18) is rotated, the connector (18a) along with the locking member (15) may also rotate. The locking member (15) may rotate and may slip out of the slots (14) of the support structure (13) to the disengaged position. The first/engaged position of the locking member locks the seat in one position by restricting the movement of the frame (4) whereas, the second/disengaged position of the locking member (15) allows the free vertical movement of the seat (1) with the frame (4).

The height adjustment assembly (100) may further include a damper (12). The damper (12) at one end may be fixedly positioned on the floor of the vehicle whereas the other end of the damper (12) may be fixedly coupled to the frame (4). The extension of the vertical section in the frame (4) may include a provision. The top end of the damper (12) may be configured to be accommodated within this provision of the extension in the frame (4). The damper (12) may be configured to attenuate the vibrations from the seat (1). The damper (12) may attenuate the vibrations that the seat (1) may be subjected to, and the damper (12) may thereby improve the driving ergonomics. In an embodiment, the damper (12) may be any known kind of attenuator including but not limited to hydraulic dampers, pneumatic dampers etc.

The working of the height adjustment assembly (100) for adjusting the height of the seat (1) is explained below with greater detail. The shaft (18) may initially be configured in the second position where the locking member (15) is disengaged from the slots (14) of the support structure (13). Consequently, the tension in the first tension member (9) and the second tension member (6) in a released condition. The first tension member (9) and the second tension member (6) are in the decompressed condition/released condition/expanded condition when the locking member (15) is in the second/disengaged position. Therefore, the frame (4) and the seat (1) are pushed upwards. The frame (4) and the seat (1) may be configured to lie at a maximum height or a maximum vertical position when the locking member (15) is disengaged from the slots (14) and when the shaft (18) is in the second position. The user may subsequently sit on the seat (1), or the user may apply pressure on the seat (1). Consequently, the first tension member (9) may be compressed and the height of the seat (1) with the frame (4) may reduce. As the height of the seat (1) with the frame (4) reduces, the user may rotate the lever (7) from the second position to the first position when the seat (1) reaches a satisfactory height. The rotation of the lever (7) may rotate the shaft (18). As the shaft (18) rotates, the connector (18a) and the locking member (15) also rotate. The locking member (15) may consequently engage with the slots (14) of the column (13b) in the support structure (13). As the locking member (15) engages with the slots (14) in the column (13b), the position of the frame (4) and the seat (1) is locked. Thus, the user may fix the required height of the seat (1) and the frame (4). If the user intends to further lower the height of the seat (1), the user may operate the lever (7) to the second position where the locking member (15) is disengaged. Subsequently, the user may apply excessive pressure onto the seat (1) and the first tension member (9) may further be compressed. When the seat (1) reaches the required height, the user may operate the lever (7) back to the first position where the locking member (15) is engaged with the slot (14) of the column (13b) in the support structure (13).

The user may completely release the seat (1) by re-operating the lever (7) back to the second position. Since, the locking member (15) is not holding the frame (4) in the fixed position, the tension first tension member (9) pushes the seat (1) and the frame (4) to the maximum height. The second tension member (6) is configured in the exemplary embodiment to be thrice as stiff as the first tension member (9). Consequently, the second tension member (6) that is positioned below the first tension member (9) does not shift or compress when pressure is applied onto the seat (1) by the user for varying the height of the seat (1). Thus, only the first tension member (9) which is of lower stiffness when compared to the stiffness of the second tension member (6), is herein used to compress/de-compress and vary the height of the seat (1). The second tension member (6) may also act as an attenuator and the second tension member (6) may primarily attenuate the vibration from the seat (1) for improved ergonomics of the seat (1). The second tension member (6) and the damper (12) absorb/attenuate the vibrations from the seat (1) together and improve the overall ergonomics of the seat (1). In an embodiment, both the first tension member (9) and the second tension member (6) may be configured with stiffness which is suitable for varying the height of the seat (1).

In an embodiment, the above illustrated height adjustment assembly (100) provides improved ergonomics to the user by enabling a simple and compact assembly (100) for varying the height of the seat (1). The assembly (1) illustrated above consumes minimal space and provides multiple height varying options to the user.

In an embodiment, the configuration of the second tension member (6) for dampening along with the damper (12) for attenuating the vibrations of the seat (1) enhances the ergonomics and driving comfort of the seat (1) as two different components attenuate the vibrations from the seat (1) and significantly reduce the vibrations on the seat (1).

Equivalents

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.

It will be understood by those within the art that, in general, terms used herein, 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 description 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, 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."

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 and spirit being indicated in the description.
