Abstract
The invention relates to 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 comprises a guide device, by means of which the upper backrest part can be linearly displaced along a displacement curve laterally past at least one side edge of the lower backrest part in such a way that the upper backrest part can also be rotated about the displacement curve and/or about a transverse axis extending in a transverse manner to the displacement curve during the lateral displacement.
Claims11
A vehicle seat, in particular a utility motor vehicle seat, comprising:
- a seat part comprising:
- a backrest that includes a lower backrest part positioned below an upper backrest part;
- and
- a holding device to which the upper backrest part is mounted such that the upper backrest part is displaceable relative to the lower backrest part, wherein the holding device comprises a guide device which enables the upper backrest part to laterally displace along a displacement curve towards at least one side edge of the lower backrest part, wherein the guide device comprises a first guide element which is arranged above and at a distance from a second guide element, wherein the first guide element forms a first curved path and the second guide element forms a second curved path, and wherein the first and the second curved paths are arranged with an axial offset that increases from a first end of the first and second guide elements to a second end of the first and second guide elements along the displacement curve, causing the upper backrest part to rotate about a substantially horizontal axis during the lateral displacement.
A vehicle seat, comprising:
- a seat part;
- a backrest, including:
- a lower backrest part;
- an upper backrest part;
- a holding device connected to the lower backrest part, wherein the upper backrest part is mounted displaceable to the lower backrest part by the holding device, wherein the upper backrest part is linearly displaceable laterally along an imaginary displacement curve past at least one side edge of the lower backrest part while the lower backrest part remains stationary with respect to the seat part, wherein the imaginary displacement curve is arranged in a plane defined by a direction of a lateral extension of the vehicle seat and a direction of a longitudinal extension of the vehicle seat;
- a guide device, the guide device including:
- at least first and second guide elements, wherein the first and second guide elements are positioned such that at least a portion of the first guide element is arranged with an axial offset that increases from a first end of the first and second guide elements to a second end of the first and second guide elements;
- and
- a second holding device, wherein the second holding device is mounted to the holding device connected to the lower backrest part, wherein the second holding device is connected to the upper backrest part by the first and second guide elements, wherein the first and second guide elements move with the upper backrest part as the upper backrest part is displaced laterally relative to the lower backrest part, and wherein the guide device defines the imaginary displacement curve.
