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

TECHNICAL FIELD
Present disclosure relates in general to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to driver ergonomics. Further, embodiments of the present disclosure disclose a gear shift lever of a vehicle, having a height adjustable and automatic locking feature.
BACKGROUND
Driver ergonomics focuses on comfort and posture of a driver in a vehicle. Driver’s comfort and posture mainly depends on the seating position and the accessibility of all the controls suited for a particular driving position in order to not strain body of the driver.
With advancements in technologies, many ergonomic features have been introduced by the automotive manufactures to improve comfort and safety of vehicle users. Some the features may include mechanisms for adjusting height of a seat in the vehicle, that enables the driver or occupants to adjust height and position of the seats. Further, the vehicles include suitable mechanisms which enable the tilt and telescopic adjustment of the steering columns. However, during driving of the vehicle, the driver may frequently shift gears often by actuating a gear shift lever provided inside a cabin of the vehicle. Further, heavy traffic conditions which involve constant stop and go circumstances, also increases the frequency at which the drivers shift gears. Additionally, the drivers may find it difficult to drive in mountainous terrain, since manoeuvring large trucks or vehicle around steep curves also requires the driver to constantly shift gears. Operating a manual transmission requires the driver to apply force to the gear knob to assure that the transmission is firmly engaged in the desired gear. Accordingly, shifting gears may often cause significant, repetitive stress on muscles that control motions of the driver's wrist, elbow and shoulder. Prolonged and continuous operation of gear levers often contributes to driver fatigue and can sometimes lead to injury.
Further, since the height and arm-length or the reach may not be always same for all of the drivers, the location or length of the gear shift lever may not be ideal for a particular driver since the length of the gear shift lever always remains fixed in conventional vehicles. Thus, the location of the gear shift lever and the distance through which the lever must be pushed or pulled is often dependent on the shape of the vehicle and the design of the transmission. As a result, drivers may not be able

to make any ergonomic adjustments to the gear shift lever and are forced to operate the gear shift lever in an already fixed position, which is undesired.
The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional braking system.

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. 1-6. It is to be noted that the gear shift lever assembly may be employed in any vehicle including but not limited to a passenger vehicle, a utility vehicle, commercial vehicles, motorcycles, and any other vehicle and other machinery.
Figs. 1 and 2 are exemplary embodiments of the present disclosure which illustrates a front view and an exploded view a gear shift lever assembly (100) [hereinafter referred to as assembly (100)]

for a vehicle. In an embodiment, the vehicle may be a passenger cars, light commercial vehicles, heavy commercial vehicles and the like. The vehicle may include a body which may be supported by wheels and a cabin defined within the body for accommodating the driver or occupants. Further, the vehicle may include the gear shift lever assembly (100) which may be disposed in the cabin. The gear shift lever assembly (100) may be configured to be operated by the driver to change the gears based on requirement. The assembly (100) may include a first member (1). The first member (1) may include one end which may be adapted to engage with a shifting fork (not shown in figures) of a transmission (not shown in figures). Further, the first member (1) may be defined with a first arm (1a) and a second arm (1b) extending parallel to each other from a portion (1c) of the first member (1) [as seen in Fig. 3a]. In an embodiment, the first arm (1a) may be defined with a plurality of slots (4) and the second arm (1b) may be defined with a protrusion (6). In an another embodiment, the second arm (1b) may be defined with both the protrusion (6) and the plurality of slots (4) which may be defined adjacent to each other.
Referring now to Figs. 3a and 3b, the plurality of slots (4) may include at least one longitudinal slot (4b) and a plurality of lateral slots (4a) which may extend from the at least one longitudinal slot (4b). In an illustrated embodiment, the first member (1) is defined with three lateral slots (4a), however, this should not be considered as a limitation as the second member (2) may be defined with less than or more than three lateral slots (4a). The at least one longitudinal slot (4b) may be defined between the first arm (1a) and the second arm (1b) of the first member (1). In an embodiment, the at least one longitudinal slot (4b) may be a cut out that may be defined between the first arm (1a) and the second arm (1b). Further, the plurality of lateral slots (4a) may be configured to extend from the at least one longitudinal slot (4b). The plurality of lateral slots (4a) may be defined in a direction that is perpendicular to the at least one longitudinal slot (4b) and the plurality of lateral slots (4a) may extend circumferentially around the first arm (1a). In an embodiment, each of the plurality of lateral slots (4a) extending from the at least one longitudinal slot (4b) may be parallel to each other and may be equidistantly positioned away from each other.
In an embodiment, each of the plurality of lateral slots (4a) may be defined with a depression (4c) at an end of the plurality of lateral slots (4a) which may be away from the at least one longitudinal slot (4b). The depression (4c) may extend in a direction that is perpendicular to the direction in

which the plurality of lateral slots (4a) may extend. For example, the depression (4c) may be small extension or cutout that may extend downwardly from each of the plurality of lateral slots (4a).
As seen in Fig. 3a, the protrusion (6) of the second arm (1b) may be defined with a first end (FE), a second end (SE), a bottom end (BE) and a top end (TE). In an embodiment, the protrusion (6) may be defined with a tapered profile which may have a thickness increasing from the bottom end (BE) towards the top end (TE). Further, the protrusion (6) may be defined with the tapered profile having the thickness increasing from the first end (FE) towards the second end (SE).
Referring back to Figs. 1 and 2, the assembly (100) may include a second member (2). The second member (2) may include one end (2a) which may be defined with a shifter knob (10). The shifter knob (10) may be operated by an operator to operate the gear shift lever assembly (100) to change gears based on requirement. Further, the second member (2) may include a body (9) which may be formed at the second end (2a) and the shifter knob (10) may be adapted to extend from the body (9). The body (9) [that is, the second member (2)] may be adapted to be movably disposed on the first member (1). Furthermore, the second member (2) may include an elongated member (5) which may extend concentrically within the body (9). The elongated member (5) may be received within the first member (1). In an embodiment, the elongated member (5) may be received within the first member (1) between the first arm (1a) and the second arm (1b). Additionally, the second member (2) may include a locking pin (3) which may be fixed to the elongated member (5). In an embodiment, the locking pin (3) may be removably accommodated in a hole (3a) that may be defined in the elongated member (5) of the second member (2). The locking pin (3) may extend outwardly in a single direction relative to the hole (3a) or may extend in both opposite directions out of the hole (3a). The locking pin (3) may be accommodated within one slot of the plurality of slots (4) when the elongated member (5) may be positioned between the first arm (1a) and the second arm (1b). The locking pin (3) may be configured to displace between each of the plurality of slots (4) corresponding to displacement of the second member (2) relative to the first member (1). Furthermore, the longitudinal movement of the locking pin (3) within the plurality of slots (4) displaces the second member (2) relative to the first member (1), which in-turn increases or decreases height of the second member (2) relative to the first member (1). In an embodiment, the locking pin (3) may be accommodated within depression of the at least one slot of the plurality of slots (4) for locking the second member (2) and the first member (1). That is, the depression (4c)

which may be formed in each of the plurality of lateral slots (4a) may be configured to accommodate the locking pin (3) to lock the second member (2) with the first member (1).
Further, referring to Figs. 2 and 4, the second member (2) may include a detent pin (7) which may be supported by the body (9). The body (9) of the second member (2) may include a provision (12) which may be configured to support the detent pin (7). Further, the assembly (100) may include a resilient member (8) which may positioned within the provision (12) and may be coupled to the detent pin (7). The resilient member (8) may be configured to bias the detent pin (7) out of the provision (12) towards the inner portion of the body (9) or the second member (2). Further, the second member (2) may include a cap (13) which may be positioned at an end of the provision (12). The cap (13) may be adapted to retain and lock the resilient member (8) firmly at the end of the provision (12) which may aid in providing the compressive force when the resilient member (8) may be under compression. The cap (13) may prevent dislocation of the resilient member (8) from its position. Additionally, the cap (13) when removed may facilitate removal and insertion of the resilient member (8) and the detent pin (7) into and out of the provision (12).
The detent pin (7) may be configured to contact the protrusion (6) when the second member (2) may be assembled on the first member (1). In an embodiment, the resilient member (8) may be configured to maintain contact between the detent pin (7) and the protrusion (6) during displacement of the detent pin (7) on the protrusion (6) between the first end (FE), the second end (SE), the bottom end (BE) and the top end (TE). Further, the detent pin (7) may be configured to ride along the protrusion (6) between the first end (FE), the second end (SE), the bottom end (BE) and the top end (TE) corresponding to displacement of the second member (2) by the operator relative to the first member (1). In an embodiment, the movement of the locking pin (3) through the plurality of lateral slots (4a) may enable relative displacement of the detent pin (7) between the first end (FE) and the second end (SE) of the protrusion (6). Further, the movement of the locking pin (3) through the at least one longitudinal slot (4b) may enable the relative longitudinal movement of the detent pin (7) between the top end (TE) and the bottom end (BE) on the protrusion (6). In an embodiment, the detent pin (7) may be configured to automatically traverse back to the first end (FE) from the second end (SE) and from the top end (TE) to the bottom end (BE) corresponding to alignment of the locking pin (3) with a corresponding lateral slot (4a), due to the

tapered profile of the protrusion (6), such that the locking pin (3) may enter the lateral slot (4a) and may get positioned in the depression (4c).
Referring now to Fig. 6, the detent pin (7) may be configured to traverse from the first end (FE) to the second end (SE) and from the bottom end (BE) to the top end (TE) of the protrusion (6) corresponding to displacement of the locking pin (3) out of the plurality of slots (4) based on operation of the shifter knob (10) by the operator. Furthermore, as seen in Fig. 5, the detent pin (7) may be configured to automatically traverse back to the first end (FE) from the second end (SE) and from the top end (TE) to the bottom end (BE) when the operator may leave the shifter knob or may allow the shifter knob (10) to freely displace, due to the tapered profile of the protrusion (6), for traversing the locking pin (3) back into a corresponding slot of the plurality of slots (4) and lock the second member (2) with the first member (1).
In an embodiment, the locking pin (3) may abut to the one slot of the plurality of slots (4) to facilitate positioning of the second member (2) relative to the first member (1). Further, as seen in Figs. 5 and 6, the locking pin (3) may be configured to traverse along a corresponding lateral slot of the plurality of lateral slots (4a) and may be accommodated in the depression (4c), such that, the circumferential movement of the second member (2) may be prevented which thereby aids in firm positioning of the second member (2) relative to the first member (1). In an embodiment, when the locking pin (3) may be positioned within or aligned with one of the plurality of lateral slots (4a) the detent pin (7) due to the tapered profile of the protrusion (6) may be biased towards the first end (FE) from the second end (SE). This biasing force enables the locking pin (3) which is connected to the second member (2) to be displaced into the corresponding slot of the plurality of lateral slots (4a) and may automatically get positioned within the depression (4c). The second member (2) may also be traversable along a vertical direction of the first member (1) due to the displacement of the locking pin (3) in the at least one longitudinal slot (4b). The second member (2) may be initially rotated by the operator till the locking pin (3) may travel out of the corresponding plurality of lateral slots (4a) into the at least one longitudinal slot (4b). The displacement of the locking pin (3) out of the plurality of lateral slots (4a) may be against the biasing force which may be exerted on the detent pin (7) by the protrusion (6). Subsequently, the second member (2) may be moved upwardly or downwardly to traverse the second member (2) vertically along the first member (1) [that is vertical displacement of the locking pin (3) within the

at least one longitudinal slot (4b)] for varying the overall height of the assembly (100). For example, this displacement of the second member (2) displaces the detent pin (7) over the protrusion (6) from the bottom end (BE) to the top end (TE), in case the height of the assembly (100) is to be increased.
In an operational embodiment, considering the locking pin (3) to be positioned within the depression (4c) of the lowermost lateral slot (4a) of the plurality of lateral slots (4a). In order to increase the overall height of the assembly (100), the operator may rotate the shifter knob (10) in an anti-clock wise direction. Due to the rotation of the shifter knob (10) in the anti-clock wise direction, the locking pin (3) may be displaced out of the depression (4c) and may be displaced out of the lowermost slot of the plurality of lateral slots (4a) and may be displaced into the at least one longitudinal slot (4b). Upon the displacement of the locking pin (3) out of the plurality of lateral slots (4a) and into the at least one longitudinal slot (4b), the locking pin (3) may be capable of displacing vertically. The displacement of the locking pin (3) from the plurality of lateral slot (4a) into the at least one longitudinal slot (4b), may result in movement of the detent pin (7) from the first end (FE) to the second end (SE) on the protrusion (6). Further, the operator may suitably lift the shifter knob (10) in an upwards direction and align the locking pin (3) with any one of the plurality of lateral slots (4a) as per the height requirement. The vertical displacement of the locking pin (3) within the at least one longitudinal slot (4b), may result in movement of the detent pin (7) from the bottom end (BE) towards the top end (TE) on the protrusion (6). Further, as seen in Fig. 5 and 6, the displacement of the detent pin (7) towards the second end (SE) and the top end (TE) on the protrusion (6) may compress the resilient member (8) coupled to the detent pin (7). The compression force exerted by the resilient member (8) may exert additional force on the detent pin (7) which may be in-turn exerted by the detent pin (7) on the protrusion (6).
Further, upon reaching the required height, the operator may let go of the shifter knob (10). As the locking pin (3) may be aligned with a corresponding lateral slot (4a) based on the required height, the locking pin (3) may automatically force to enter the corresponding lateral slot (4a) and may get positioned within the depression (4c) of the corresponding lateral slot (4a) to lock the second member (2) with the first member (1) at the required height. The automatic movement of the locking pin (3) into the corresponding lateral slot (4a) and into the depression (4c) may be facilitated by the biasing force which may be exerted by the tapered profile of the protrusion (6)

which forces the detent pin (7) to traverse back towards the bottom end (BE) and the first end (FE), respectively. This biasing force may be amplified by the compressive force which may be exerted on the detent pin (7) by the resilient member (8). The biasing force towards the bottom end (BE) and the first end (FE) of the protrusion (6) facilitates automatic displacement of the locking pin (3) to enter the corresponding lateral slot (4a) and the depression (4c). This configuration of the assembly (100) enables easy height adjustment and automatic locking of the second member (2) with the first member (1) at the required height.
In an embodiment, the assembly (100) may include a guide clip (11) [as seen in Fig. 2] which may be employed between the first member (1) and the second member (2). The guide clip (11) may facilitate the elongated member (5) of the second member (2) to be slidably positioned within the first member (1). Additionally, the guide clip (11) may be configured to prevent excessive vertical movement of the second member (2) relative to the first member (1) thereby retaining the elongated member (5) within the first member (1).
In an embodiment, the vertical/linear movement of the assembly (100) is achieved, and the accessibility of the gear knob may be suitably varied according to the user’s comfort and reach. Thus, by imparting a vertical movement of the assembly (100), the user can change the position of the assembly (100) according to individual comfort. Consequently, the user could reduce fatigue and avoid long term health issues. In an embodiment of the disclosure, the assembly (100) can be easily configured between the existing gear shaft and the gear knob. The assembly (100) provides a simple arrangement for improving the ergonomics of the lever without any modifications to the transmission, gear box or the chassis of the vehicle.
In an embodiment, the assembly (100) is easy to assemble, manufacture and maintain.
In an embodiment, the assembly (100) facilitates adjustment to a gear shift throw as per the operator’s requirement.
It should be imperative that the construction and configuration of the assembly and any other elements or components described in the above detailed description should not be considered as a limitation with respect to the figures. Rather, variation to such structural configuration of the elements or components should be considered within the scope of the detailed description.

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, 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.”
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.
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.
