Abstract: The invention concerns a vehicle seat with a seat upper part comprising a seat part and a back rest, and with a seat lower part, wherein between the seat upper part and the seat lower part is arranged a height-adjustable seat frame with at least two scissor arms connected rotatably together, wherein at least a first end of at least one of the scissor arms is connected with at least one slide element for sliding displacement of the first end in at least one displacement direction along at least one guide rail, wherein the slide element has at least one flexibly formed pressure force element to exert a pressure force directed against the guide rail.

Abstract: Device for vehicle seat occupancy detection, wherein a base frame which can be adjusted in the height direction of a vehicle seat and which is composed of at least two scissors arms which are connected to one another is arranged between a seat part of the vehicle seat and a vehicle body part, the device comprising a first detector which is attached to at least one of the scissors arms and which, when the vehicle seat is occupied by a minimum weight, detects a predefinable height setting of the scissors arm which is lower than a maximum possible height setting, and at least one spring which is fixed to at least one of the scissors arms and the predefinable pretensioned spring force of which corresponds at most to the downward-acting weight force due to the minimum weight and counteracts the latter.

Abstract: The invention relates to a vehicle seat having a device for vehicle seat occupancy detection, wherein a base frame which can be adjusted in the height direction of the vehicle seat and which is composed of at least two scissors arms which are connected to one another is arranged between a seat part of the vehicle seat and a vehicle body part, wherein the base frame can be adjusted in the height direction by means of at least one gas spring, wherein the gas spring is connected to a pressure sensor, by means of which an exceeding of a predefinable pressure threshold value can be detected upon a transition of the vehicle seat from an unoccupied state to a state occupied by a minimum weight due to a change in pressure within the gas spring which is brought about as a result of the transition.
