Description

TECHNICAL FIELD

[0001] The present invention relates to a seat device for a tiltable vehicle, in particular for a tiltable vehicle comprising an opposed-cylinder engine. BACKGROUND ART

[0002] In a tiltable vehicle, the seat device is fixed to a vehicle component or a vehicle frame at least on a side facing away from the traveling direction. Therefore, the seat device and the vehicle frame, in particular the long seat connected to the vehicle frame and the vehicle frame, are kinematically coupled to each other.

[0003] If the tiltable vehicle includes an opposed-cylinder engine, the cylinders of the opposed-cylinder engine can be arranged offset in the longitudinal direction with respect to an intermediate bearing. Due to this offset, the tiltable vehicle is subjected to a rotational impulse about the vertical axis of the tiltable vehicle. Thus, vibrations can be generated, which can be transmitted to the seat device and can be felt as uncomfortable by the user of the tiltable vehicle. SUMMARY OF THE INVENTION

[0004] An object of an embodiment of the present invention is to reduce vibrations occurring in the seat device during the operation of the tiltable vehicle.

[0005] The object is achieved by a seat device for a tiltable vehicle, in particular for a tiltable vehicle comprising an opposed-cylinder engine, the seat device comprising: at least one long seat; at least one holding device by which the long seat is arranged or can be arranged on a vehicle component or a vehicle frame of the tiltable vehicle on a side facing the traveling direction, and by which the movement of the long seat parallel to the vertical axis and the transverse axis can be restricted; and at least one coupling device which is fixed or can be fixed to a side of the long seat facing away from the traveling direction, by which the long seat is indirectly or directly fixably or can be fixably arranged with limited movement on the vehicle frame, the coupling device comprising at least one first coupling component indirectly or directly fixed to the long seat, at least one second coupling component fixed to the vehicle frame, and at least one first movement clearance component arranged between the first coupling component and the second coupling component, by which, by means of a relative movement of the first coupling component relative to the second coupling component, the long seat can move with limited movement relative to the vehicle frame at least on the transverse axis of the tiltable vehicle or inclined to the transverse axis.

[0006] Because: The seat device includes a coupling device, wherein the bench seat can be fixed to the seat frame with limited movement indirectly or directly via a first coupling device and a second coupling device and a play device provided between the first coupling device and the second coupling device, so the vibration transmitted from the vehicle frame to the bench seat can be compensated or buffered. Therefore, the driving experience of the user of the tiltable vehicle can be improved.

[0007] The coupling device can be arranged on the bottom side of the bench seat facing the vehicle frame.

[0008] A tiltable vehicle can be understood as a bicycle, a motorcycle or a motorcycle-like motor vehicle, such as a moped, especially a two-wheeled, three-wheeled or four-wheeled moped, a scooter, a tiltable tricycle, a four-wheeler or the like.

[0009] Furthermore, according to the invention, the coupling device includes at least one rod-shaped or strip-shaped flexurally rigid spacing device, by means of which the bench seat can be fixed to the vehicle frame indirectly or directly, which spacing device is arranged between the bench seat and the vehicle frame, and on one end of which a first coupling device or a second coupling device is arranged.

[0010] By means of the rod-shaped or strip-shaped flexurally rigid spacing device, the bench seat can be fixed to the vehicle frame at a distance from the vehicle frame. In this case, the first coupling device or the second coupling device can be arranged on the rod-shaped or strip-shaped flexurally rigid spacing device.

[0011] In an expansion of the just-mentioned embodiment, it has proven to be advantageous if the spacing device extends in the driving direction or against the driving direction from the end of the bench seat facing away from the driving direction.

[0012] If the tiltable vehicle includes an opposed-cylinder engine, wherein vibrations are generated due to rotational impulses about a vertical axis, it can prove to be advantageous if the coupling device is displaced in the direction of the center of the tiltable vehicle. In this case, the vibrations that can be transmitted in the direction of the bench seat with respect to the vehicle frame are reduced due to the favorable smaller centrifugal forces.

[0013] To fix the spacing device, it has proven to be advantageous if the coupling device includes at least one fixing device, by means of which the spacing device is fixed or can be fixed to the bench seat or the vehicle frame on the side of the spacing device opposite the first play device.

[0014] In this case, the spacing device can be fixed to the bench or to the vehicle frame by means of the at least one fixing device. Accordingly, the first coupling device, the second coupling device and the play device are arranged at the end of the spacing device opposite the at least one fixing device and are thus fixed to the vehicle frame or to the bench.

[0015] In order to further improve the spring or damping buffering of the vibrations transmitted to the bench in terms of the vehicle frame, it is provided in an extension of the embodiment just mentioned that the coupling device comprises at least one second play device which is arranged or can be arranged between the fixing device and the receiving part of the bench or the receiving part of the vehicle frame, and by means of the second play device, by means of the relative movement of the fixing device with respect to the receiving part, the bench can be moved relative to the vehicle frame at least on the transverse axis of the tiltable vehicle or at an angle to this transverse axis in a limited manner.

[0016] In order to further limit the movement possibilities of the bench relative to the vehicle frame, it has proven advantageous for the coupling device to comprise at least two fixing devices spaced apart from one another and at least two second play devices, the spacing device being fixed or fixable to the bench or the vehicle frame by means of the fixing devices, each second play device being assigned to one fixing device.

[0017] Since at least two fixing devices spaced apart from one another are provided, movement of the bench around at least one fixing device with a radius corresponding to the length of the spacing device is prevented.

[0018] The first play device and / or the second play device can in principle be configured arbitrarily, provided they fulfill the technical function of allowing a limited relative movement of the first coupling device with respect to the second coupling device or the fixing device. The first play device and / or the second play device can be implemented technically simply if the first play device and / or the second play device have damping devices, in particular elastic sleeves, elastically deformable or dimensionally stable bushes and / or stepped bolts.

[0019] In order to further reduce the transmission of vibrations from the vehicle frame or vehicle components in the direction of the bench of the seat device, an embodiment of the seat device comprises a damping device which comprises at least one damping element, the damping element being arranged or can be arranged on the bench and / or on the vehicle frame or vehicle components, the damping element being able to bear in contact with its free end against the vehicle frame or vehicle components or the bench, and forces acting along the vertical axis being able to be buffered by means of the damping element.

[0020] Via the at least one damping element, oscillations and / or vibrations acting in the direction of the vertical axis can be cushioned. In addition, the bench seat or the vehicle frame or the vehicle component can move relative to the at least one damping element. If the damping element is fixed to the bench seat, the damping element bears against the vehicle frame or the vehicle component in a contacting manner, thus allowing a sliding movement of the vehicle frame or the vehicle component relative to the damping element. Conversely, if the damping element is fixed to the vehicle frame or the vehicle component, the bench seat is movable relative to the damping element.

[0021] To further improve the damping effect, in an extension of the just-mentioned embodiment, it is provided that the at least one damping element of the damping device comprises at least two sections that extend in the direction of the vertical axis in a sheet-like manner and are spaced apart from each other by a gap.

[0022] Thus, small vibrations can be absorbed by the at least one damping element, and the bench seat or the vehicle frame or the vehicle component does not perform a relative movement relative to the damping element. In addition, in this case, the service life of the damping element is improved.

[0023] Furthermore, in an embodiment of the seat device, it is provided that the holding device is configured in a hook shape or a loop shape, and the bench seat is arranged or can be arranged on the vehicle component or the vehicle frame of the motor vehicle on the side facing the driving direction by means of the holding device, and the bench seat can be arranged to engage into the holding device with a correspondingly configured, in particular complementarily configured, loop or hook.

[0024] In this case, the bench seat can be simply arranged on the holding device and is only released against the driving direction for removal. Conversely, if the bench seat is fixed to the vehicle frame via a coupling device, the bench seat is fixed.

[0025] Other features, details and advantages of the present invention result from the drawings and the following description of the preferred embodiments of the seat device. Description of the Drawings

[0026] The drawings are as follows:

[0028] Figure 2 A perspective side view showing a first embodiment of the spacing device of the coupling device of the seat device;

[0029] Figure 3 A perspective side view showing a second embodiment of the spacing device of the coupling device of the seat device. Detailed Description of the Embodiment

[0030] Figure 1 A seat device generally provided with reference numeral 2 is shown, which seat device is for at least one tiltable vehicle 4 (only partially described in the drawings), and the tiltable vehicle includes an opposed-cylinder engine (not explicitly described in the drawings). The seat device 2 includes a bench seat 6, which bench seat is described in a top view on a side facing the tiltable vehicle. Figure 1 The seat device 2 includes a holding device 8, and the bench seat 6 is fixed to a vehicle component 12 of the tiltable vehicle 4 on a side facing the traveling direction 10 by means of the holding device. In Figure 1 the illustrated embodiment, the holding device 8 is configured as a loop, and the bench seat 6 is arranged to engage into the holding device with correspondingly configured, in particular complementarily configured, hooks 14.

[0031] Furthermore, the seat device 2 includes a coupling device 16. The coupling device is fixed or can be fixed on a side of the bench seat 6 facing away from the traveling direction 10. By means of the coupling device 16, the bench seat 6 can be fixed to the vehicle frame 18. For this purpose, the coupling device 16 includes a first coupling element 20 indirectly fixed to the bench seat 6 and a second coupling element 22 fixed to the vehicle frame 18. In order to ensure a limited relative movement of the first coupling element 20 relative to the second coupling element 22, the coupling device 16 includes a first play device 24, and the bench seat 6 can be moved relative to the vehicle frame 18 at least on or inclined to the transverse axis of the tiltable vehicle 4 by means of the first play device by means of the relative movement of the first coupling element 20 relative to the second coupling element 22.

[0032] In the illustrated embodiment, the coupling device 16 includes a bar-shaped or strip-shaped bend-rigid spacing device 26, and the bench seat 6 can be coupled to the vehicle frame 18 by means of this spacing device. In the illustrated embodiment, the spacing device 26 includes the first coupling element 20 and the play device 24 on a side facing away from the traveling direction 10.

[0033] Furthermore, it can be seen from the drawings that the spacing device 26 is fixed to the bench seat 6 by two fixing devices 28. A second play device 30 is respectively provided on each fixing device 28, and this second play device is arranged between the fixing device 28 and a receiving portion of the bench seat 6, and by means of this second play device, the bench seat 6 can be moved relative to the vehicle frame 18 at least on or inclined to the transverse axis of the tiltable vehicle 4 by means of the relative movement of the fixing device 28 relative to the receiving portion.

[0034] Furthermore, the seat device 2 includes a damping device 32, which damping device includes a plurality of damping elements 34 in the illustrated embodiment. In Figures 1 - 3In the embodiments described, these damping elements are fixed on the side of the bench seat 6 facing the vehicle frame 18. In one arrangement of the bench seat 6, the damping elements 34 of the damping device 32 bear against the vehicle frame 18 or against the vehicle component 12.

[0035] Figure 2 Shows a first embodiment of the seat device 2, in which the coupling device 16 comprises a first play device 24 which is formed by an elastic sleeve. Since the rubber sleeve is used as the first play device 24, the movement of the first coupling device 20 relative to the second coupling device 22 is ensured, and at the same time the buffering of vibrations is achieved due to the elastic deformability of the rubber sleeve.

[0036] Figure 3 Shows a second embodiment of the seat device 2, in which the first play device 24 of the coupling device 16 is formed by a bush. A fixing element such as a screw or a bolt can be guided in the bush, and the bush itself can move limitedly between the first coupling device 20 and the second coupling device 22.
