Abstract

A vehicle seat, in particular a utility motor vehicle seat, having a seat part, having a backrest comprising a lower backrest part and an upper backrest part, and having a holding device, by means of which the upper backrest part is mounted displaceably with respect to the lower backrest part, wherein the holding device has a sliding guide device, by means of which the upper backrest part is arranged displaceably with respect to the lower backrest part along a displacement curve so as to mount the upper backrest part displaceably at least in part past the side edge of the lower backrest part.

First claim

What is claimed is:

1. A vehicle seat, comprising:
a seat part, having a backrest comprising a lower backrest part and an upper backrest part by means of which a driver's torso can be additionally supported, and having a holding device, by means of which the upper backrest part is mounted displaceably with respect to the lower backrest part,
wherein
the holding device has a sliding guide device comprising two sliding guide elements, by means of which the upper backrest part and the two sliding guide elements are arranged displaceably with respect to the lower backrest part along a displacement curve, wherein the displacement curve is defined by the two sliding guide elements so as to mount the upper backrest part displaceably at least in part in the direction of a side edge of the lower backrest part.

2. The vehicle seat according to claim 1 ,
wherein
the two sliding guide elements are arranged mutually parallel jointly centrally together in a vertical plane in the region of the first end and are not arranged centrally in a shared vertical plane in the region of a second end resulting in that the upper backrest part additionally rotates about the displacement curve and/or about an axis extending at an angle to the displacement curve, preferably about a transverse axis extending transverse to the displacement curve, during a lateral displacement.

3. The vehicle seat according to claim 1 ,
wherein
the two sliding guide elements are arranged side by side and at a distance from one another, the two sliding guide elements being arranged skewed with respect to one another, at least in part, in a helical configuration.

4. The vehicle seat according to claim 1 ,
wherein
the sliding guide elements include at least one sliding guide element that is slidably guided in a sliding bearing element.

5. The vehicle seat according to claim 4 ,
wherein
the at least one sliding bearing element comprises a sliding bearing bush having a reduced sliding surface as a result of material recesses on a sliding inner surface thereof.

6. The vehicle seat according to claim 4 ,
wherein
the at least one sliding bearing element comprises resilient support arm elements which form a slide bush.

7. The vehicle seat according to claim 1 ,
further comprising: a sliding bearing element holder, by means of which the at least two sliding bearing elements are held above one another.

8. A utility motor vehicle, in particular an agricultural utility motor vehicle, with at least one vehicle seat,
characterised by a vehicle seat according to claim 1 .
