Seat Device for a Tilting Vehicle

Abstract

A seat device for a tilting vehicle includes: at least one seat body which has a seat surface on which a user of the tilting vehicle can be disposed and to which a force acting in a direction of action can be applied, the direction of action running transversely to the seat surface; at least one support unit which has at least one resiliently flexible and/or deformable first support portion on which the seat body is disposed, at least one rigid, non-flexible second support portion, and at least one cavity extending parallel or obliquely to the seat surface and disposed between the first support portion and the second support portion, by which cavity the first support portion and the second support portion are spaced apart from each other without touching and by which an elastic deformation of the first support portion toward the cavity is enabled. At least one adjustment unit has at least one adjustment body which is disposed movably in the cavity and by which the first support portion is supported against the second support portion and can be transferred from a first support position to a second support position.

13. The seat apparatus according to claim 11, wherein a first adjustment member is movable by a translational movement in a movement direction, which extends transversely or obliquely relative to the active direction, from the first support position into the second support position, and/or a second adjustment member is movable by rotation about a rotation axis which extends centrally or eccentrically through the second adjustment member from the first support position into the second support position.

14. The seat apparatus according to claim 11, wherein the hollow space comprises a continuous recess which is accessible from an outer side in an access direction which extends transversely relative to the active direction and transversely relative to a movement direction of the at least one adjustment member.

15. The seat apparatus according to claim 11, wherein the at least one adjustment member is configured to be resiliently deformable or rigid at least in the active direction of the force.

16. The seat apparatus according to claim 11, wherein the at least one adjustment member abuts the first carrier portion and/or the second carrier portion in a linear or planar manner.

17. The seat apparatus according to claim 11, further comprising: at least two adjustment members, in a state coupled together, are movable from the first support position, into the second support position, and/or at least two adjustment members are movable individually and independently of each other from the first support position into the second support position.

18. The seat apparatus according to claim 11, wherein the first carrier portion and the second carrier portion form a common integral component.

19. The seat apparatus according to claim 18, wherein the carrier unit comprises a two-component injection-molded part.

20. The seat apparatus according to claim 11, wherein the seat member comprises an upholstery member or a plastics component.

21. The seat apparatus according to claim 11, wherein the seat member and the carrier unit form a common integral component.

22. The seat apparatus according to claim 21, wherein the seat member and the carrier unit form a multi-component injection-molded part.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0036] FIG. 1 is a side view of an exemplary embodiment of the seat apparatus.

DETAILED DESCRIPTION OF THE DRAWING

[0037] FIG. 1 shows a seat apparatus which is generally designated 2 for a tilting vehicle (not explicitly shown in the Figures). The seat apparatus 2 comprises a seat member (body) 4 which has a seat face (surface) 6. A user of the tilting vehicle can be arranged on the seat face 6. As a result of the inherent weight of the seat member 4 and as a result of the, where applicable, additional weight of one or more users of the tilting vehicle, the seat member 4 can be acted on with a force which acts in an active direction 8.

[0038] Furthermore, the seat apparatus 2 comprises a carrier (support) unit 10 which comprises at least one resiliently bendable and/or deformable first carrier portion 12, on which the seat member 4 is arranged. Furthermore, the carrier unit 10 comprises a substantially rigid, non-flexible, second carrier portion 14. A hollow space (cavity) 16, by which the first carrier portion 12 and the second carrier portion 14 are spaced apart from each other, extends between the first carrier portion 12 and the second carrier portion 14.

[0039] The seat apparatus 2 further comprises an adjustment unit 18 which comprises two adjustment members 20 in the exemplary embodiment shown in the figure. The adjustment members 20 are movably arranged in the hollow space 16. Both the first carrier portion 12 and the second carrier portion 14 are supported on the adjustment members 20. The two adjustment members 20 can be moved from a first support position, in which the first carrier portion 12 comprises a first spring rate, into a second support position, in which the first carrier portion 12 comprises a second spring rate which differs from the first spring rate. In the exemplary embodiment shown in FIG. 1, the two adjustment members 20 can be arranged independently of each other.

[0040] FIG. 1 shows an exemplary embodiment of the seat apparatus 2, in which the adjustment members 20 can be moved by a translational movement in a movement direction 22, which extends transversely relative to the active direction 8, from the first support position into the second support position.

[0041] The hollow space 16 of the exemplary embodiment shown in FIG. 1 is in the form of a continuous recess which is accessible from the outer side from an access direction 24 which extends transversely relative to the active direction 8 and transversely to the movement direction 22.

[0042] In the exemplary embodiment shown in FIG. 1, the carrier unit 10 is in the form of an integral component, in particular a multi-component injection-molded part. The first carrier portion 12 is formed in this instance by a first plastics material and the second carrier portion 14 is formed by a second plastics material.

[0043] The features of the invention as disclosed in the present description, claims and drawings may be significant both individually and in any combination in the implementation of the invention in the different embodiments thereof.
