Abstract

A headrest for a vehicle seat, in particular for a motor vehicle seat, is proposed. The headrest includes a padded part facing the head of a seat occupant, a basic part and a comfort-adjustment device. When the headrest is in use, the padded part can be adjusted by the comfort-adjustment device relative to the basic part from a first position, in which it is further away from the head of the seat occupant, into a second position, closer to the head of the seat occupant. The comfort-adjustment device has two control elements which can be set in a locking position and in an unlocking position, the movement of the control elements being synchronized.

First claim

The invention claimed is:

1. A headrest for a vehicle seat, the headrest comprising:
a padded part facing the head of a seat occupant;
a main body; and
a comfort-adjustment device disposed at a lower part of the padded part,
wherein, when the headrest is in use, the padded part can be adjusted by the comfort-adjustment device relative to the main body by movement of the padded part from a first position, in which it is further away from the head of the seat occupant, to a second position, closer to the head of the seat occupant,
wherein the movement of the padded part is a pivoting movement of the padded part about an axis of rotation extending substantially horizontally,
wherein the axis of rotation is at an upper part of the padded part, such that the lower part of the padded part is displaced toward the head of the seat occupant more than the upper part during the movement of the padded part from the first position to the second position,
wherein the comfort-adjustment device has two control elements, which can be set in a locking position and in an unlocking position, the movement of the control elements being synchronized, and
wherein a direct movement of the padded part from the first position to the second position is possible when the control elements are in the locking position, but a movement of the padded part in the opposite direction is blocked and, when the control elements are in the unlocking position, a direct movement of the padded part from the first position to the second position and from the second position to the first position is possible.

2. The headrest as claimed in claim 1 , wherein the synchronization of the control elements is provided by a synchronization rod,
wherein the padded part can also be adjusted by the comfort-adjustment device from the second position in the direction of the first position, this requiring the setting of an extreme forward position of the padded part, and
wherein the adjustment force required to move the padded part from the first position thereof toward the second position thereof is increased in the region of the extreme forward position.

3. The headrest as claimed in claim 1 , wherein the main body is configured to receive a portion of the padded part when in the first position.

4. The headrest as claimed in claim 1 , wherein the main body is configured to cover a portion of the padded part facing away from the head of a seat occupant.
