A coupling device is arranged interactively between the seat-part-side upper part and the body-side lower part, and includes a deformable suspension element as a first coupling element and a bearing and deformation device as a further coupling element.

The invention relates to a vehicle seat comprising a vehicle seat upper part and a vehicle seat lower part, which are spaced apart from one another along a height axis and are connected to one another by means of a scissor frame arrangement, wherein the scissor frame arrangement comprises at least one inner swinging arm and at least one outer swinging arm, wherein the at least one inner swinging arm and the at least one outer swinging arm are mechanically coupled, whereby an angle of inclination of the vehicle seat upper part relative to the vehicle seat lower part can be specified, wherein the mechanical coupling comprises an arm element and a first connecting element pivotably connected thereto, wherein the angle of inclination can be specified by a length of the first connecting element.

The invention relates to a vehicle seat having a lower part and an upper part displaceable in a height direction relative to the lower part, the lower part and the upper part being connected to one another in a manner displaceable relative to one another by means of a connecting unit, and a height adjustment unit being provided which is intended and designed to adjust a spacing of the lower part from the upper part, wherein the vehicle seat has a light display unit comprising a light source and a deflection unit for deflecting light of the light source, the light display unit being provided and adapted to output a first light indication when the spacing of the lower part to the upper part is outside a predetermined target area and to output a second light indication when the spacing is within the target area during a first operating state of the vehicle seat.

A kinetic seat cushion assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat cushion assembly includes a primary seat cushion frame, a secondary seat cushion frame, a seat cushion tilt mechanism coupling the secondary seat cushion frame to the primary seat cushion frame such that the secondary seat cushion frame is movable with respect to the primary seat cushion frame, and a front pivot mechanism that pivotally couples a front portion of the primary seat cushion frame to a front portion of the secondary seat cushion frame.

A pneumatic adjustment arrangement for a vehicle seat. The pneumatic adjustment arrangement has at least one chamber or bladder, which can be filled with a pressure medium, as an adjustment element. Furthermore, the pneumatic adjustment arrangement has a fluid line for the filling and/or evacuation of the chamber. Additionally, the pneumatic adjustment arrangement has a valve device which is provided in the fluid line for volume flow regulation. Finally, the pneumatic adjustment arrangement has a noise absorber which is likewise arranged in the fluid line in order to absorb noise generated in the fluid line. In this way, it is possible to create a pneumatic adjustment arrangement for a vehicle seat, in particular for comfort functions, such that objectionable noises during the execution of the comfort fiction are reduced.

The invention relates to a vehicle seat with a horizontally movable seating surface for receiving a person, a retaining means which can be rigidly connected to a vehicle, and a horizontal spring system and a vertical spring system, wherein both the horizontal and vertical spring systems are configured as fluid systems, wherein the fluid systems are supplied by a central fluid supply and the fluid system of the horizontal spring system being separated from the fluid system of the vertical spring system by at least one valve.

A compressed air system for a motor vehicle with an air supply system, including: an electric drive motor, which can be controlled for variable speed, an air compressor coupled to be driven by the electric drive motor, an electric power supply for supplying electric power to the electric drive motor, at least one air reservoir connected with the air compressor to receive air from the air compressor, an air utilization system connected to the at least one air reservoir to receive air from the at least one air reservoir, a controller to control the speed of the electric drive motor. The controller controls the electric drive motor to determine the speed of the electric drive motor so that during filling of the air reservoir, when the pressure level in the air reservoir passes a setpoint that is between a minimum level and a higher cut off pressure level, the controller changes the compressor speed so that specific power consumption per unit mass of air compressed is decreased.

The invention relates to an adjustable damping system for a vehicle seat for damping a movement of the seat part-side upper part relative to the body-side lower part in at least one spatial direction, wherein, for damping, at least one damping element is provided, which is adjustable by an adjustment device and is arranged between the seat part-side upper part and the body-side lower part. The damping system is further distinguished in that a first damping force of the damping element is settable by the adjustment device, wherein this first damping force can be determined by the adjustment device, with the aid of a total damping travel of the damping element, a basic damping force presettable by a damping setting device, a position of the seat part-side upper part, measurable by a sensor device, relative to the body-side lower part and a movement direction of the seat part-side upper part relative to the body-side lower part, wherein the movement direction can be determined from at least two temporally consecutive positions of the seat part-side upper part, measurable by the sensor device, relative to the body-side lower part.

An adjustable suspended seat apparatus having a tuned frequency-tailored damping through stratified seat structure is described. The damping seat structure includes: a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer. A second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer, the first material or the second material having an adjustable damping characteristic. The suspended seat apparatus includes a seat base configured to have the seat coupled thereto; a suspension system coupled to the seat base, the suspension system comprising: an adjustment feature configured to adjust operation of the suspension system; and a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle.

A vehicle includes a chassis and a seating system. The seating system includes a frame coupled to the chassis, a seat cushion supported by at least one of the frame and a floor of the vehicle, a first recoverable insert configured to provide a first energy attenuation response, and a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response. The seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system.
