Abstract: The invention relates to a spring device for a vehicle seat, in particular a utility vehicle seat having at least one air spring arranged between a seat part and a lower part for the height adjustment (5) of the seat part and having a control device for controlling the supply and discharge of at least one additional air volume to or from the air spring, wherein at a predefined run in and/or run out position (9) of the air spring, the additional air volume that can be supplied or discharged can be changed or switched off by means of the control device such that inclines in the profile of a force-path air spring characteristic (1; 1a, 1b, 1c) of the air spring in a first and in at least one further range (2, 3,4) are different from one another. Furthermore, a description is given of a method of springing a vehicle seat.

Abstract: The invention relates to a vehicle with a seat part, a backrest part, and a side part, particularly an armrest part, for collectively supporting a vehicle operator in his seated position on the vehicle seat, wherein the vehicle seat is characterized in that a supplemental vehicle operator support device that is arranged on the side part of the vehicle seat, and that can be temporarily arranged in an otherwise vehicle seat-free support area, and by means of which a vehicle operator seated on the vehicle seat can be additionally supported when in a laterally or rear-oriented seated working position.

Abstract: The invention relates to a vehicle seat comprising a seat part, comprising a back rest part and comprising a linear guide device for translational adjustment of the vehicle seat, in which the linear guide device comprises a guide rail means and a slide rail means which is displaceable with respect thereto, in which a bearing means interacts between the slide rail means and the guide rail means and at least comprises slide rod elements so as to mount the slide rail means with respect to the guide rail means, and in which the slide rod element comprises an elongate undulating base body, the slide rod element having an effective external diameter which is greater, at least when the slide rod element is radially unloaded, than a core external diameter of the elongate undulating base body.

Abstract: The invention relates to a vehicle seat with a seat part and with a seat back part for supporting a driver of the vehicle in the sitting position on the vehicle seat, wherein the vehicle seat is characterized by an additional vehicle driver's torso support device which can be disposed outside the seat part and the seat back part and which can be temporarily disposed at least partially in an otherwise seat-free torso support region at the level of or above the upper third of the seat back part in front of the seat back part and laterally off-centre on the seat back part, in order to provide support, laterally off-centre of the seat back part, at least at the level of the shoulder or chest region of the driver who is sitting on the vehicle seat when he adopts a seated working posture oriented to the side or backwards, wherein the additional vehicle driver's torso support device is disposed so as to be movable by a moving device from a parked position into an additional torso support position in the otherwise se

Abstract: The invention relates to a vehicle seat having a seat part, having a backrest part and having an upholstery part for upholstering the seat part, wherein the upholstery part comprises an upholstery part cover element, a carrier layer element for supporting the upholstery cover element, an upholstery core element, a main upholstery element and a barrier layer, and wherein the main upholstery element is spatially separated by the barrier layer from the carrier layer element, the upholstery core element and the upholstery part cover element, the barrier layer having a seamless barrier layer element, which is arranged continuously as a strip product directly on the main upholstery element.

Abstract: The invention relates to a vehicle seat with a seat part and with a seat back part for supporting a driver of the vehicle in the sitting position on the vehicle seat, wherein the vehicle seat has an additional vehicle driver's torso support device which can be disposed outside the seat part and the seat back and which can be temporarily disposed at least partially in an otherwise seat-free torso support region in front of the seat back part and laterally and/or above the seat back part, in order to provide support, laterally off-centre of the seat back part, at least at the level of the shoulder region of the driver who is sitting on the vehicle seat when he adopts a seated working posture oriented to the side or backwards, and wherein the additional vehicle driver's torso support device comprises a seat back extension device which is disposed on the seat back part (3) so as to be movable in translation along a horizontal axis in order to be able to move the additional vehicle driver's torso support device su

Abstract: Spring-mounted vibration system to reduce vibration with a first spring-mounted part and a second spring-mounted part, wherein the first spring-mounted part and the second spring-mounted part can oscillate relative to each in at least one vibration direction and at least one of the spring-mounted parts can be exposed to a return force on a vibration movement. A control unit is arranged with at least one travel linkage which is connected with at least one of the spring-mounted parts and in which is arranged displaceably at least one guide element connected with a spring element generating the return force and/or the other spring-mounted part.
