Description

BACKGROUND AND SUMMARY OF THE INVENTION

Exemplary embodiments of the invention relate to a vehicle seat having an adjusting device, and to a vehicle having such a vehicle seat having an adjusting device.

Conventional vehicle seats can generally be adjusted vertically and in a longitudinal direction, either separately or in combination. The longitudinal adjustment of vehicle seats, i.e., the adjustment along the vehicle longitudinal axis, is usually effected via a system of rails and carriages. Vehicle seats held rotatably about a vertical axis on a rotation plate are also known.

German utility model specification DE 20 2007 002 243 U1 discloses a height adjusting device of a vehicle seat, which contains two control valves to control the degree of filling of at least one compressed-air actuator, which maintains the seat body at a desired height level and at the same time supports it in a vertically resilient manner, each of which control valves is assigned an actuating member that cooperates with a control slide, such that, when there is a usage-dependent change in the weight supported by the at least one compressed-air actuator, a relative switching movement between the control slide and the respective associated actuating member takes place, causing the switching of the control valves. The relative switching movement is a linear movement, with both control slides being arranged on a control carriage mounted in a linearly displaceable manner in the direction of the switching movement.

U.S. Pat. No. 8,585,146 B1 discloses a seat for a vehicle, wherein the seat has an adjustment mechanism having locking boxes, a suspension system made of a woven mesh, retractable armrests, a movable headrest, and movable leg rests.
