DETAILED DESCRIPTION OF THE DRAWINGS

[0029] FIG. 1 shows a seat device, provided overall with the reference sign 2, for at least one tilting vehicle 4 (only partially illustrated in the figures) comprising a boxer engine (not explicitly illustrated in the figures). The seat device 2 comprises a seat bench 6 which is illustrated in FIG. 1 in a top view of the side facing the tilting vehicle. The seat device 2 comprises a holder 8, by means of which the seat bench 6 is fixed to a vehicle component 12 of the tilting vehicle 4 on a side facing the direction of travel 10. In the exemplary embodiment shown in FIG. 1, the holder 8 is designed in the manner of an eyelet, in which the seat bench 6 can be arranged so as to engage therein with a hook 14 formed in a corresponding, in particular complementary, manner.

[0030] Furthermore, the seat device 2 comprises a coupling unit 16 which can be fixed or is fixed to a side of the seat bench 6 facing away from the direction of travel 10. The seat bench 6 can be fixed to a vehicle frame 18 by the coupling unit 16. For this purpose, the coupling unit 16 comprises a first coupler 20, which is fixed indirectly to the seat bench 6, and a second coupler 22, which is fixed to the vehicle frame 18. In order to ensure a limited movement of the first coupler 20 relative to the second coupler 22, the coupling unit 16 comprises a first movement clearance device 24, by means of which the seat bench 6 is movable to a limited extent relative to the vehicle frame 18, at least in or transversely to the transverse axis of the tilting vehicle 4, by means of movement of the first coupler 20 relative to the second coupler 22.

[0031] In the case of the exemplary embodiment shown in the figures, the coupling unit 16 comprises a rod- or strip-shaped, flexurally rigid spacer 26 which can be used to couple the seat bench 6 to the vehicle frame 18. In the exemplary embodiments shown in the figures, the spacer 26 comprises the first coupler 20 and the movement clearance device 24 on its side facing away from the direction of travel 10.

[0032] Furthermore, it can be seen in the figures that the spacer 26 is fixed to the seat bench 6 by two fastener 28. A second movement clearance device 30 is arranged on each of the fastener 28, the second movement clearance device being arranged between the fastener 28 and a mounting of the seat bench 6 and by means of which the seat bench 6 is movable to a limited extent relative to the vehicle frame 18, at least in or transversely to the transverse axis of the tilting vehicle 4, by means of movement of the fastener 28 relative to the mounting.

[0033] Furthermore, the seat device 2 comprises a damping unit 32 which, in the exemplary embodiments shown in the figures, comprises a plurality of damping elements 34. In the exemplary embodiments illustrated in FIGS. 1 to 3, the damping elements are fixed on that side of the seat bench 6 which faces the vehicle frame 18. In an arrangement of the seat bench 6, the damping elements 34 of the damping unit 32 lie on the vehicle frame 18, and/or on the vehicle component 12.

[0034] FIG. 2 shows a first exemplary embodiment of the seat device 2 in which the coupling unit 16 comprises a first movement clearance device 24 which is formed by an elastic grommet. The use of a rubber grommet as first movement clearance device 24 ensures movement of the first coupler 20 with respect to the second coupler 22 and at the same time permits damping of vibrations because of the elastic deformability of the rubber grommet.

[0035] FIG. 3 shows a second exemplary embodiment of the seat device 2 in which the first movement clearance device 24 of the coupling unit 16 is formed by a bushing. A fixing element, such as a screw or pin, can be guided in the bushing, and the bushing per se is movable to a limited extent between the first coupler 20 and the second coupler 22.

[0036] The features of the invention disclosed in the above description, in the claims and in the drawing may be essential both individually and also in any desired combination for realizing the invention in its various embodiments.
