<p>The invention relates to an actuating means (1) for the head restraint of a vehicle seat, at least part of which head restraint can be shifted from a comfort position into a safety position in the event of an accident. The actuating means (1) is in this case provided with limbs (3.1 to 3.4) which are expanded from an initial position as a consequence of pressure loading and therefore bring about a lengthening which can be transmitted to force transmission means. According to the invention, the limbs (3.1 to 3.4) are connected to one another and/or to fastening elements by means of joints (6.1 to 6.3) which each have a long joint pin (8.3) and a short joint pin (8.2) which can be inserted axially into holes (9) in order to form the joints (6.1 to 6.3). As an addition or alternative, the outer limbs (3.1, 3.4) can have projections (15.1, 15.2) which penetrate the metal structure of the vehicle seat, in particular in the region of a crossmember (5), to the rear from the occupant's side and are suitable for the attachment of a force transmission means, in particular the core and sheath of a Bowden cable.</p> |
