Abstract

A head restraint includes a central part, a fastener for fastening the central part to a backrest of a vehicle seat, and at least one side wing. The side wing is mounted pivotably in relation to the central part between the neutral position and at least one comfort position, and is fixable at least in the comfort position. The fastener is designed to mount the central part pivotably relative to the backrest about a horizontal pivot axis. The central part is pivotable between a parking position and at least one supporting position and is fixable at least in the supporting position.

First claim

What is claimed:

1. A head restraint, comprising:
a central part;
a fastener for fastening said central part to a backrest of a vehicle seat, said fastener including two struts and a horizontal pivot axis extending between said two struts, wherein said two struts are arranged parallel to one another and extend into said backrest; and
at least one side wing pivotally attached to said central part wherein said central part is displaceable about said horizontal pivot axis between a parking position and at least one supporting position and said at least one side wing is displaceable between a neutral position and at least one comfort position, wherein said central part extends in a plane across a top of said backrest when in said parking position.

2. The head restraint as claimed in claim 1 , wherein the head restraint comprises two side wings which are arranged laterally on the central part.

3. The head restraint as claimed in claim 2 , wherein the side wings are pivotable about two pivot axes which are arranged mirror-symmetrically with respect to each other.

4. The head restraint as claimed in claim 3 , wherein imaginary extensions of the pivot axes which are arranged mirror-symmetrically with respect to each other intersect at a point on a side of the horizontal pivot axis about which the central part is pivotably mounted.

5. The head restraint as claimed in claim 1 , wherein the central part is trapezoidal, wherein, in the supporting position, the shorter base of the trapezoid faces a backrest of a vehicle seat.

6. The head restraint as claimed in claim 1 , wherein the fastener comprises means for adjusting the height of the head restraint.

7. The head restraint as claimed in claim 1 , wherein the fastener has at least one ratchet wheel with an associated pawl for engaging in the ratchet wheel for releasable fixing of the central part , and at least one release element for releasing the pawl from the engagement with the associated ratchet wheel.

8. The head restraint as claimed in claim 7 , wherein the pawl fixes the associated ratchet wheel via a spring element.

9. A vehicle seat comprising a backrest and the head restraint as claimed in claim 1 .

10. The vehicle seat as claimed in claim 9 , wherein the backrest of the vehicle seat can be folded down.

11. The head rest of claim 1 , wherein said central part extends in said plane across upper ends of said two struts when in said parking position.
