DESC:FIELD OF THE INVENTION

[0001] The present disclosure relates to a seat assembly for a vehicle. More particularly the present disclosure relates to a suspension system for a seat assembly of the vehicle.

BACKGROUND

[0002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

[0003] Generally, the seats of a vehicle such as an automotive vehicle are used for sitting for a user for long periods. In addition, the seat facilitates the isolation of the user from the vibrations/shocks from the vehicle. A typical seat assembly for the passenger compartment of an automotive vehicle usually includes a structural frame adapted to be mounted on a base plate of a vehicle. The structural frame is supported by an upholstered and cushioned portion that provides a comfortable seat to the user. However, the seat assembly of the vehicle is not adapted to absorb the vibrations/shocks from the vehicle. In some cases, the vehicle suspension system is provided with shock absorbers but that is limited to absorbing vertical loads and the user is prone to longitudinal and lateral loads making the ride uncomfortable.

[0004] Accordingly, there is a need for a suspension system for a seat assembly for the vehicle that is adapted to absorb the vibration in the lateral and the longitudinal direction, so that the driver can use the seat for a long duration with more comfort.

[0005] The drawbacks/difficulties/disadvantages/limitations of the conventional techniques explained in the background section are just for exemplary purposes and the disclosure would never limit its scope only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks/disadvantages of the conventional arts which are not explicitly captured above.

SUMMARY

[0006] This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.

[0007] The present disclosure relates to a suspension system for a seat assembly of a vehicle. The suspension system includes a bottom plate securely coupled with a portion of the vehicle, a top plate securely coupled with a base of the seat assembly and slidably coupled with the bottom plate, and a damper coupled with the top plate and the bottom plate and disposed between the top plate and the bottom plate. In addition, the suspension system includes a shaft coupled with the bottom plate and disposed between the top plate and the bottom plate, a pair of springs disposed on two ends of the shaft, and a mandrel securely coupled with the top plate and slidably coupled on the shaft and disposed between the pair of springs. Upon a receipt of lateral forces on the seat assembly the top plate slides on the bottom plate and the damper and the pair of springs are adapted to absorb the amplitude of vibrations between the top plate and the bottom plate.

[0008] The damper may facilitate the absorption of the shocks and minimize the amplitude of the vibrations between the top plate and the bottom plate. In addition, the suspension system may include a mandrel adapted to be securely coupled with the top plate and slidably coupled with the bottom plate, and a pair of springs to facilitate the absorption of the lateral load by having a relative motion between the top plate and the bottom plate.

[0009] The suspension system includes the damper and a spring thereby facilitating the absorption of the shocks along a lateral direction. In addition, the springs help to minimize the amplitude of vibrations by providing a restoring force that opposes the displacement caused by the vibration. Further, the damper facilitates absorbing or dissipating the energy of the vibrating of the vehicle. Also, the suspension system is customizable and may be installed on any vehicle such as but not limited to an ATV, a tractor, a commercial vehicle, a passenger vehicle, or any other seat assembly adapted to include vibrations.

[0010] Further, the mandrel facilitates damping and reducing the vibration exerted on the seat assembly and the user and further facilitates limiting the lateral movement of the seat assembly. This provides a stable experience and no tilting of the user along the two sides of the vehicle while turning or cornering.

[0029] Embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings.

[0030] Referring to Figure 1 and Figure 2 a suspension system 100 for a seat assembly for a vehicle is shown. Specifically, Figure 1 illustrates a top-perspective view of the suspension system 100, in accordance with an embodiment of the present disclosure. Figure 2 illustrates an exploded view of the suspension system 100, in accordance with an embodiment of the present disclosure. Figure 3 illustrates a top view of the suspension system 100 with a top plate 102 removed, in accordance with an embodiment of the present disclosure.

[0031] As shown in Figure 1 to Figure 3, the suspension system 100 may be adapted to be mounted between a vertical suspension of the seat assembly and a base of a seat portion (not shown) to facilitate absorption and damping of the lateral forces within the vehicle. The suspension system 100 may include the top plate 102 adapted to couple with a base of the seat portion, a bottom plate 104 adapted to couple with a portion of the vehicle. In an embodiment, the bottom plate 104 of the vehicle is adapted to couple with the top of a fore-aft seat adjustment unit or a vertical suspension unit or a floor or a skid plate or a base plate (not shown) of the vehicle.

[0032] In addition, suspension system 100 may include a pair of guide rails 106 sandwiched between the top plate 102 and the bottom plate 104 to facilitate the sliding motion of the top plate 102 with the bottom plate 104. The sliding motion of the top plate 102 relative to the bottom plate 104 may facilitate a movement of the seat assembly with reference to a transverse axis (Y-Y’) of a vehicle.

[0033] In addition, the suspension system 100 may include a damper 108 having a first end 108a adapted to couple with the bottom plate 104 and a second end 108b disposed opposite to the first end 108a and adapted to couple with the top plate 102. Further, the suspension system 100 includes a shaft 142 coupled with the bottom plate 104 and disposed between the top plate 102 and the bottom plate 104.

[0034] Furthermore, the suspension system 100 includes a pair of springs 150 disposed along the two opposite ends of the shaft 142 and a mandrel 214 securely coupled with the top plate 102. In addition, the mandrel 214 is slidably coupled on the shaft 142 and disposed between the pair of springs 150 on the shaft 142. Upon a receipt of lateral forces on the seat assembly the top plate 102 slides on the bottom plate 104 and the damper 108 and the pair of springs 150 absorbs the amplitude of vibrations between the top plate 102 and the bottom plate 104 thereby dampening the vibrations to reach the seat assembly.

[0035] In an embodiment, the damper 108 absorbs the frequency generated by the pair of springs 150 through an incompressible fluid flowing within a cylinder of the damper 108. The damper 108 and the pair of springs 150 dampen the frequencies between the top plate 102 and the bottom plate 104 thereby moving to an equilibrium condition with restricting the vibrations between the top plate 102 and the bottom plate 104 thereby maintaining a stable position of the seat assembly.

[0036] In an embodiment, the first end 108a may include a piston part of the damper 108 and the second end 108b may include a cylindrical part of the damper 108. In other embodiment (not shown), the first end 108a may include a cylindrical part of the damper 108 and the second end 108b may include a piston part of the damper 108 without departing from the scope of the present disclosure.

[0037] In an embodiment, the damper 108 may facilitate the absorption of the shocks and minimize the amplitude of the vibrations between the top plate 102 and the bottom plate 104. In an embodiment, the suspension system 100 may include a lock assembly (not shown) to facilitate the locking and unlocking of the top plate 102 with the bottom plate 104.

[0038] As shown in Figure 1 to Figure 4, the bottom plate 104 of suspension system 100 may include a first portion 112 and a second portion 114 disposed parallel and spaced apart from the first portion 112. In an embodiment, the first portion (112) and the second portion (114) are disposed substantially parallel along a transverse axis (Y-Y’) of the vehicle.

[0039] The first portion 112 of the bottom plate 104 and the second portion 114 of the bottom plate 104 may be similar in design, shape, size, and configuration, so for the sake of clarity and brevity, only the first portion 112 of the bottom plate 104 is explained. In an illustrated embodiment, the first portion 112 of the bottom plate 104 may be adapted to position on the top of the vertical suspension unit or a fore-aft adjustment unit or a portion of a vehicle such that the first portion 112 may be positioned towards a front of the seat portion and the second portion 114 may be positioned towards a back portion of the seat portion of the seat assembly. In an embodiment, the first portion 112 and the second portion 114 may be disposed parallel to a transverse axis (Y-Y’) of the vehicle.

[0040] Referring to Figure 4, the first portion 112 and the second portion 114 of the bottom plate 104 are shown, in accordance with an embodiment of the present disclosure. The first portion 112 of the bottom plate 104 defines a longitudinal shape configuration having a first longitudinal side 120, a second longitudinal side 122 extending parallel and spaced apart from the first longitudinal side 120.

[0041] In addition, the first portion 112 of the bottom plate 104 may include a first lateral end 124 extending between the first longitudinal side 120 and the second longitudinal side 122, a second lateral end 126 disposed spaced apart from the first lateral end 124. In an embodiment, the second lateral end 126 of the first portion 112 of the bottom plate 104 may be adapted to extend between the first longitudinal side 120 and the second longitudinal side 122.

[0042] In addition, the first portion 112 of the bottom plate 104 may include a first surface 128 adapted to face towards the top plate 102 and a second surface (not shown) disposed opposite to the first surface 128 and adapted to couple with a top of the vertical suspension unit or a fore-aft adjustment unit a floor or a skid plate or a base plate of the vehicle or a portion of the vehicle without departing from the scope of the present disclosure. Further, the first longitudinal side 120 and the second longitudinal side 122 of the first portion 112 of the bottom plate 104 may include a pair of sidewalls 130 extending orthogonally outwardly away from the first surface 128 of the first portion 112 of the bottom plate 104.

[0043] In an example, the first longitudinal side 120 includes a first sidewall 130a extending outwardly away from the first surface 128 and the second longitudinal side 122 may include a second sidewall 130b extending outwardly away from the first surface 128. In addition, the second sidewall 130b extends outwardly from the second longitudinal side 122. Further, a portion of the second sidewall 130b is disposed proximate to the first lateral end 124 may include a collar 133 securely coupled with the second sidewall 130b.

[0044] Further, the first surface 128 of the first portion 112 may include a first slide rail 134 extending longitudinally on the first portion 112. The first slide rail 134 may include a fixed bracket 136 securely coupled with the first surface 128 of the first portion 112. In addition, the first slide rail 134 includes a moving bracket 138 slidable coupled with the fixed bracket 136 and adapted to slide linearly on the fixed bracket 136. Furthermore, the moving bracket 138 may be coupled with the top plate 102 such that the linear movement of the moving bracket 138 facilitates the lateral movement of the seat portion along a transverse axis (Y-Y’) of the vehicle.

[0045] Furthermore, the first surface 128 of the first portion 112 may include a pair of flanges 140 adapted to protrude outwardly from the first surface 128. The pair of flanges 140 may include a pair of holes extending within the pair of flanges 140 such that the holes are aligned with one another. In an embodiment, the shaft 142 may be extended between the pair of flanges 140 such that the shaft 142 rests within the pair of holes of the flanges 140.

[0046] In an embodiment, the shaft 142 may include a first end 144 disposed proximate to the first lateral end 124 and a second end 146. The second end 146 of the shaft 142 may be disposed opposite to the first end 144 and disposed proximate to the second lateral end 126. In an embodiment, the flange 140 may include a sleeve, a washer, a rubber, a circlip, and a lock pin to facilitate the locking of the shaft 142 with the flange 140 without departing from the scope of the present disclosure.

[0047] As shown, the shaft 142 may include the pair of springs 150 adapted to rest on the shaft 142 such that the pair of springs 150 may be adapted to be disposed on the shaft 142. In an embodiment, the pair of springs 150 mounted on the shaft 142 facilitates the absorption of the amplitude of the lateral forces to the seat assembly. In an embodiment, the pair of springs 150 are adapted to compress in the receipt of any forces to facilitate the absorption of the forces. In an embodiment, the pair of springs 150 are adapted to expand to facilitate the absorption of the forces.

[0048] In an example, the pair of springs 150 may include a first spring 150a adapted to be disposed proximate to the first end 144 of the shaft 142, and a second spring 150b disposed proximate to the second end 146 of the shaft 142 without departing from the scope of the present disclosure.

[0049] In an embodiment, the first spring 150a is adapted to compress and the second spring 150b is adapted to expand upon a receipt of the forces to facilitate the absorption of the forces without departing from the scope of the present disclosure. In another embodiment, the first spring 150a is adapted to expand and the second spring 150b are adapted to compress upon a receipt of the forces to facilitate the absorption of the forces without departing from the scope of the present disclosure. In another embodiment, the first spring 150a and the second spring 150b is adapted to expand or compress together or alternatively to facilitate the absorption of the forces without departing from the scope of the present disclosure.

[0050] As shown in Figure 4, the first spring 150a may be adapted to extend from the first end 144 of the shaft 142 to partially away from the first end 144. Similarly, the second spring 150b may be adapted to extend from the second end 146 of the shaft 142 to partially away from the second end 146 such that a gap extends between the positioning of the first spring 150a and the second spring 150b.

[0051] As shown in Figure 4, the second portion 114 may be similar to the first portion 112 of the bottom plate 104 and includes all the elements, of the same size shape, and dimensions without departing from the scope of the present matter.

[0052] Referring to Figure 5 and Figure 6, the top plate 102 of the suspension system 100 is shown. Specifically, Figure 5 illustrates a portion of a top perspective view of the top plate 102, in accordance with an embodiment of the present disclosure. Figure 6 illustrates a top perspective view of the first portion 112 of the bottom plate 104, in accordance with an embodiment of the present disclosure.

[0053] As shown in Figure 1 to Figure 2 and Figure 5 to Figure 6, the top plate 102 may be adapted to be positioned over the bottom plate 104. In addition, the top plate 102 may be securely coupled with the moveable bracket 138 of the first slide rail 134 so as to facilitate the sliding motion of the top plate 102 with reference to the bottom plate upon receipt of lateral forces by the vehicle.

[0054] As shown in Figure 4, Figure 5 and Figure 6, the top plate 102 may include a first portion 202 adapted to be positioned over the first portion 112 of the bottom plate 104. In addition, the top plate 102 may include a second portion 204 disposed parallel and spaced apart from the first portion 202 and adapted to be positioned over the second portion 114 of the bottom plate 104.

[0055] In an illustrated embodiment, the top plate 102 may include a connecting portion 206 to facilitate the connection of the first portion 202 with the second portion 204 such that the connecting portion 206 may be adapted to be positioned over the second lateral end 126 of the first portion 112 and a lateral end of the second portion 114.

[0056] In another embodiment, the top plate 102 may include the first portion 202 and the second portion 204 thereby facilitating a cutout portion extending between the two portions 202, 204 to facilitate the reduction of the overall weight of the suspension system 100.

[0057] The first portion 202 and the second portion 204 of the top plate 102 are similar in design, shape, size, and configuration, so for the sake of clarity and brevity, only the first portion 202 of the top plate 102 is explained below.

[0058] As shown, the first portion 202 of the top plate 102 includes a first surface 208 adapted to face towards the base of the seat portion of the vehicle, and a second surface 210 disposed opposite to the first surface 208 and adapted to face towards the bottom plate 104 of the suspension system 100. In addition, the first portion 202 of the top plate 102 includes a pair of openings 212 extending from the first surface 208 to the second surface 210 to facilitate the accessing of the portions of the bottom plate 104.

[0059] As shown, the pair of opening 212 may be separated and disposed spaced apart from one another. In an embodiment (not shown), the opening 212 may be a single opening extending longitudinally. In an illustrated embodiment, the pair of openings 212 facilitate the accessing of the shaft 142 and the pair of springs 150 such as the first spring 150a and the second spring 150b may be accessed without removing any disassembly. In an embodiment, accessing of the shaft 142 and the pair of springs 150 through the pair of the openings 212 facilitates better lubrication of the pair of the springs 150 and the shaft 142.

[0060] As shown in Figure 2, Figure 5 and Figure 6, the suspension system 100 having the mandrel 214 adapted to be securely coupled with the second surface 210 of the first portion 202 of the top plate 102. In addition, the mandrel 214 may be adapted to rest within the shaft 142 such that the pair of springs 150 may be disposed of on the two sides of the mandrel 214. In an embodiment, the mandrel 214 is adapted move on the shaft 142 in receipt of the force and facilitates the compression and expansion of the pair of springs 150 to absorb the amplitude of vibrations between the top plate 102 and the bottom plate 104.

[0061] Referring to Figure 7, a perspective view of the mandrel 214 is shown, in accordance with the embodiment of the present disclosure. As shown, the mandrel 214 may include an outer housing 214a adapted to couple with the second surface 210 of the first portion 202 of the top plate 102 and a hollow cylinder 214b adapted to rest inside the outer housing 214a. In an embodiment, the hollow cylinder 214b of the mandrel 214 facilitates the positioning of the mandrel 214 on the shaft 142.

[0062] As shown in Figure 2, Figure 5, Figure 6, and Figure 7, the mandrel 214 may be adapted to be positioned between the first spring 150a and the second spring 150b. The two springs 150a, 150b are adapted to abut the mandrel 214 along their respective first ends and adapted to abut the flanges 140 disposed opposite to one another along their respective second ends.

[0063] Further, a secure coupling of the outer housing 214a of the mandrel 214 with the top plate 102 and the movable coupling of the mandrel 214 on the shaft 142 that is securely coupled on the bottom plate 104 facilitates a relative movement of the mandrel 214 with the bottom plate 104. The relative movement of the mandrel 214 results in the relative movement of the bottom plate 104 with reference to the top plate 102.

[0064] In an embodiment, movement of the mandrel 214 is achieved via the compression and the expansion of the two springs 150a, 150b and the movement of the mandrel 214 between the two springs 150a, 150b. In an example, while turning of the vehicle or while the vehicle is following any circumferential path, the seat assembly is adapted to receive lateral force (centripetal force) due to the weight of a user and the weight of the seat assembly. The lateral force/centripetal force acting on the vehicle in the lateral direction (along the transverse axis of the vehicle (Y-Y’) facilitates the movement of the mandrel 214 within the two springs 150a, 150b.

[0065] The lateral forces result in the movement of the top plate 102 in the lateral direction resulting in compression and the extension of the springs 150a, 150b. In an embodiment, the mandrel 214 may limit the compression and the extension of the springs 150a, 150b thereby preventing the movement of the top plate 102 beyond a predefined limit. In an embodiment, the movement of the mandrel 214 may be 25mm in the two opposite directions. In this manner, the mandrel 214 along with the two springs 150 a, 150b absorb the vibration along the lateral direction of the vehicle thereby improving the stability of the user.

[0066] Further, the damper 108 may be coupled with the bottom plate 104 along the collar 133 disposed on the second longitudinal side 122 of the first portion 112 of the bottom plate 104 along the first end 108a. Additionally, the second end 108b of the damper 108 may be coupled with an edge 216 of the first portion 202 of the top plate 102. In an embodiment, the collar 133 and the edge 216 of the first portion 202 of the top plate 102 may include a sleeve, a washer, a rubber, a circlip, and a lock pin to facilitate the locking of the damper 108.

[0067] The first portion 202 and the second portion 204 of the top plate 102 are similar in design, shape, size, and configuration. Additionally in an illustrated embodiment, the second portion 204 may include an edge 218 that is similar to the edge 216 of the first portion 202.

[0068] The advantages of the suspension system 100 are now explained. The suspension system 100 includes the damper 108 and the springs 150 thereby facilitating the absorption of the shocks along the lateral directions. In addition, the springs 150a, 150b help to minimize the amplitude of vibrations by providing a restoring force that opposes the displacement caused by the vibration. Further, the damper 108 facilitates absorbing or dissipating the energy of the vibrating of the seat assembly.

[0069] Also, the suspension system 100 may be customizable and may be installed on any vehicle such as but not limited to an ATV, a tractor, a commercial vehicle, a passenger vehicle, or any other seat assembly adapted to include vibrations. Further, the mandrel 214 facilitates damping and reducing the vibration exerted on the seat assembly and the user and further facilitates limiting the lateral movement of the seat assembly. This provides a stable experience with no tilting of the user along the two sides of the vehicle while tilting or cornering.

[0070] While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
