Abstract

A headrest element may have a central supporting region and two lateral supporting regions. The lateral supporting regions may be pivotable with respect to the central supporting region about a side pivot axis, which may run at least substantially parallel to a supporting surface of the central supporting region, in such a manner that an angle of the supporting surfaces of the lateral supporting regions can in each case be adjusted variably with respect to the supporting surface of the central supporting region. The central supporting region and the lateral supporting regions may be jointly pivotable about a transverse pivot axis, which runs at least substantially perpendicular to the side pivot axes, in such a manner that an adjustment of the supporting regions in the longitudinal direction of the vehicle is possible. A headrest using the headrest element is also described.

First claim

The invention claimed is:

1. A headrest element, comprising a central supporting region and two lateral supporting regions, wherein
the lateral supporting regions are pivotable with respect to the central supporting region, each about a separate side pivot axis, which side pivot axes runs at least substantially parallel to a supporting surface of the central supporting region, in such a manner that an angle of supporting surfaces of the lateral supporting regions can in each case be adjusted variably with respect to the supporting surface of the central supporting region, and
the central supporting region and the lateral supporting regions are jointly pivotable about a transverse pivot axis, which transverse pivot axis runs at least substantially perpendicular to the two side pivot axes, in such a manner that an adjustment of the supporting regions in the longitudinal direction of the vehicle is possible;
wherein the lateral fastening regions are each mounted at a central fastening region so as to be pivotable about the two side pivot axes;
a basic body is provided, the position of which is adjustable in the longitudinal, transverse and/or vertical direction;
the basic body has a fastening recess which is designed for receiving and for fastening an inclination adjustment hook;
the basic body and the inclination adjustment hook form a unit which is covered with a covering;
a holding element comprising a bearing element which projects through an upper recess of the covering and engages in a corresponding bearing element of the basic body, and
the two bearing elements form a pivot bearing by the holding element being pivotable about the transverse pivot axis.

2. The headrest element as claimed in claim 1 , wherein the holding element has the central fastening region for the fastening of a central supporting cushion forming the central supporting region, and two lateral fastening regions for the fastening in each case of a lateral supporting cushion forming the two lateral supporting regions.

3. The headrest element as claimed in claim 1 , wherein a basic body is provided, the position of which is adjustable in the longitudinal, transverse and/or vertical direction.

4. The headrest element as claimed in claim 3 , wherein the basic body has a fastening recess which is designed for receiving and for fastening an inclination adjustment hook.

5. The headrest element as claimed in claim 4 , wherein the basic body and the inclination adjustment hook form a unit which is covered with a covering.

6. The headrest element as claimed in claim 5 , wherein
a latching element is arranged at a lower end of the holding element, said latching element projecting through a lower recess of the covering and being in mechanical interaction with the inclination adjustment hook, and
the latching element has a latching structure into which the inclination adjustment hook latches in various positions.

7. The headrest element as claimed in claim 1 , wherein
a latching element is arranged at a lower end of the holding element, said latching element projecting through a lower recess of the covering and being in mechanical interaction with the inclination adjustment hook, and
the latching element has a latching structure into which the inclination adjustment hook latches in various positions.

8. A headrest comprising a headrest element as claimed in claim 1 .
