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.

Vehicle seat with upper part, lower part, and light display unit

A vehicle seat having a suspension unit for cushioning the rolling and vertical suspension movements of the vehicle seat, wherein the vehicle seat has a vehicle seat upper part and a vehicle seat lower part, wherein the vehicle seat upper part and the vehicle seat upper part are connected by means of the suspension unit so that the vehicle seat upper part and the vehicle seat lower part are movable relative to one another, wherein the suspension unit has a scissor arrangement having a first scissor arm and a second scissor arm, the suspension unit is rotatably connected about a first axis of rotation to the vehicle seat lower part and comprises a spring element support and a first spring element, wherein a displacement element is provided which is mounted displaceably with respect to the vehicle seat lower part, wherein the first spring element is connected on the one hand to the displacement element and on the other hand to the spring element support, which is rotatably connected about a second axis of rotation to the first scissor arm and rotatably connected about a third axis of rotation to the second scissor arm.

Vehicle seat having a suspension unit for cushioning rolling and vertical suspension movements

Vehicle seat having a suspension unit or cushioning the rolling and vertical suspension movements of the vehicle seat, wherein the vehicle seat has a vehicle seat upper part and a vehicle seat lower part, wherein the vehicle seat upper part and the vehicle seat lower part are connected by means of the suspension unit so that the vehicle seat upper part and the vehicle seat lower part are movable relative to one another, wherein the suspension unit has a scissor arrangement having a first scissor arm and a second scissor arm, wherein the suspension unit is connected rotatably about a first axis of rotation to the vehicle seat lower part and comprises a spring element support and a first fluid spring element and a second fluid spring element, wherein the first fluid spring element and the second fluid spring element are each connected to the vehicle seat lower part and to the spring element support which is rotatably connected about a second axis of rotation to the first scissor arm and rotatably connected about a third axis of rotation to the second scissor arm, wherein a fluid can be pumped between the first fluid spring element and the second fluid spring element by means of a pump unit, so that the vehicle seat upper part is substantially in a horizontal position.

Cushioning rolling and vertical suspension movements

The invention relates to a control element, in particular for a vehicle seat, comprising a second element which is arranged to be movable relative to a first element, wherein the second element is connected to a Bowden cable and is lockable relative to the first element, wherein the control element comprises a spring element, on which a first latching element is provided, wherein the first latching element presses against a second latching element through the spring force of the spring element, whereby the first latching element and the second latching element latch, wherein the first element and the spring element are formed in one piece and the second latching element is arranged on the second element, or the second element and the spring element are formed in one piece and the second latching element is arranged on the first element.

Control element

A vehicle seat having a lower part and an upper part displaceable relative to the lower part in a longitudinal direction, and a spring element for cushioning longitudinal horizontal movements of the upper part relative to the lower part. A scissors frame connects the lower part and the upper part so that they can move relative to one another. The spring element comprises a first holding arm connected to the upper part, and a second holding arm connected to the scissors frame. The first holding arm and the second holding arm are connected to one another by a first connecting element such that the first holding arm is displaced towards the second holding arm during a displacement of the upper part relative to the lower part. A resiliently deformable spring element part is deformed during a displacement of the first holding arm relative to the second holding arm.

Spring element and vehicle seat having a spring 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.

Vehicle seat with scissor frame arrangement

Vehicle seat having a pitching spring unit, a vehicle seat upper part and a vehicle seat lower part of the vehicle seat being connected such that they can be moved relative to one another by means of a scissor frame arrangement, comprising a first scissor arm and a second scissor arm which cross in a first region as viewed in a vehicle seat width direction, the pitching spring unit comprising a spring element carrier and a spring element, the spring element being connected on one side to the vehicle seat upper part, the vehicle seat lower part or the scissor arms and on the other side to the spring element carrier which is connected to the first scissor arm such that it can be rotated about a second rotational axis and to the second scissor arm such that it can be rotated about a third rotational axis.

Vehicle seat having a pitching spring unit

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 Z and are connected to one another by means of a scissor frame arrangement, wherein at least two damping elements are provided between the vehicle seat upper part and the vehicle seat lower part, the at least two damping elements each extending, inclined at an angle of attack &#x3b1;, relative to a first axis parallel to the height axis.

The invention relates to a vehicle seat having a suspension unit for cushioning the rolling and vertical suspension movements of the vehicle seat, wherein the vehicle seat has a vehicle seat upper part and a vehicle seat lower part, wherein the vehicle seat upper part and the vehicle seat upper part are connected by means of the suspension unit so that the vehicle seat upper part and the vehicle seat lower part are movable relative to one another, wherein the suspension unit comprises a scissor arrangement having a first scissor arm and a second scissor arm, characterised in that the suspension unit is rotatably connected about a first axis of rotation to the vehicle seat lower part and comprises a spring element support and a first spring element, the first spring element being connected on the one hand to the vehicle seat lower part and on the other hand to the spring element support which is rotatably connected about a second axis of rotation to the first scissor arm and rotatably connected about a third axis of rotation to the second scissor arm, and the first spring element being preferably arranged at a first angle to a vehicle seat width direction and at a second angle to a vehicle seat height direction.
