Horizontal seat adjustment means
The invention relates to a seat for a vehicle, in particular for all-terrain vehicles, with at least one seat area extending in the longitudinal direction (X) of the vehicle and in the width-wise direction (Y) of the vehicle for receiving a person, a backrest for supporting the back of the person and a holding device connected in the vertical direction (Z) under the seat area and to the latter for keeping the seat area at a distance from a coupling region for coupling the seat to the vehicle, wherein the holding device has at least one spring device for the movable arrangement at least for a time of at least the seat area with respect to the coupling region in the longitudinal direction (X) of the vehicle and/or in the width-wise direction (Y) of the vehicle.
1. A seat for a vehicle, comprising at least one seat area extending in the longitudinal direction (X) of the vehicle and in the width-wise direction (Y) of the vehicle for receiving a person, a backrest for supporting the back of the person and a holding device connected in the vertical direction (Z) under the seat area and to the latter for keeping the seat area at a distance from a coupling region for coupling the seat to the vehicle, wherein the holding device has at least one spring device for a movable arrangement of at least the seat area with respect to the coupling region in the longitudinal direction (X) of the vehicle and/or in the width-wise direction (Y) of the vehicle, wherein the spring device is formed by at least one fluid spring element, which is variable in a receiving volume and extends in an elongate manner between two application regions and onto which pressing forces are capable of being applied at an inclination to its longitudinal direction (L) with a deformation device for deforming the fluid spring element.
2. The vehicle seat according to claim 1 , wherein the deformation device is part of the spring device and forms a receiving region through which the fluid spring element extends.
3. The vehicle seat according to claim 2 , wherein two contact elements form the receiving region and have contact face portions which are configured to contact the fluid spring element during movement of the seat area in response to a sufficient displacement force.
4. The vehicle seat according to claim 3 , wherein the contact face portions are bent at least locally.
5. The vehicle seat according to claim 1 , wherein the fluid spring element is connected at least for a time in a communicating manner to a gas source for altering a spring characteristic line.
6. The vehicle seat according to claim 5 , wherein the gas source is a compressed gas source and/or a gas spring arranged in order to cushion vertical pulses.
7. The vehicle seat according to claim 6 , wherein at least one sensor unit is provided in order to detect seat movements and/or vehicle movements wherein the at least one sensor unit transmits data to a control device for actuating the compressed gas source.
8. The vehicle seat according to claim 7 , wherein the at least one sensor unit detects seat movements and/or vehicle movements in the longitudinal direction (X) of the vehicle and/or in the width-wise direction (Y) of the vehicle.
9. The vehicle seat according to claim 1 , wherein with a first stimulus of the vehicle seat a first quantity of a gas is capable of being provided in the fluid spring element, and with a second stimulus a second quantity of gas is capable of being provided in the fluid spring element, wherein the second stimulus is stronger than the first stimulus and the second quantity of gas is greater than the first quantity of gas.
10. The vehicle seat according to claim 9 , wherein with the second stimulus the fluid spring element is capable of being deformed by a retraction movement of the deformation device in a first direction and is capable of being returned by an extension movement of the deformation device in a second direction opposed to the first direction, wherein a gas is capable of being supplied to the fluid spring element during the retraction movement of the deformation device in order to increase the spring force exerted by the fluid spring element upon the deformation device and gas is capable of being withdrawn during the extension movement in order to reduce a recoil.
11. The vehicle seat according to claim 9 , wherein at least one additional volume for supplying or receiving gas is connected at least for a time in a communicating manner to the fluid spring element.
12. The vehicle seat according to claim 1 , wherein a quantity of gas in the fluid spring element is capable of being set manually by means of an actuating element.
13. The vehicle seat according to claim 1 , wherein the vehicle seat is configured for use in an all-terrain vehicle.
14. The vehicle seat according to claim 1 , wherein the fluid spring element is a pneumatic spring element.
15. The vehicle seat according to claim 1 , wherein the deformation device bends the fluid spring element.
