Abstract: A head rest for a vehicle seat includes: at least one first section that is oriented towards the head of the seat occupant, a second section, and a third section, wherein the second section is arranged essentially between the first and third sections. In the event of an accident, the first section can be displaced in the direction of displacement, due to the effect of a relative displacement of the second section from a working position into a safety position in the direction of the head of the seat occupant. The relative movement of the sections is a rotation about an essentially parallel rotational axis in the direction of displacement. A mounting of the first section in relation to the second section is provided during the relative displacement about the rotational axis. The first section comprises a first bearing surface and the second section comprises a second bearing surface.

Abstract: A headrest for a vehicle seat has a first section that is oriented towards the head of a seat occupant, a second section, and a third section. The second section is arranged between the first and third sections. In the event of an accident, the first section may be displaced, due to the relative displacement of the second section, from a working position into a safety position and a comfort position in the direction of the head of the occupant. The relative movement of the sections is a rotation about a rotational axis substantially parallel to the direction of displacement.

Abstract: A head rest for a vehicle seat has at least one first section of the head rest that is oriented towards the head of the seat occupant, a second section, a third section, and a blocking device in which the second section is arranged essentially between the first and third sections. The first section can be displaced, due to the relative displacement of the second section, from a working position into a safety position and a comfort position. The blocking device blocks or minimizes the displacement of the first section of the head rest. The blocking device is asymmetrical in relation to a central plane of the head rest and can be actuated by an actuation element that is arranged symmetrically in relation to the central plane.

Abstract: The invention relates to a head rest for a vehicle seat in which, in the event of an accident, at least one first section of the head rest that is oriented towards the head of the seat occupant can be displaced, due to the effect of a relative displacement of a second section of the head rest that is arranged essentially between the first section and the third section, from a working position into a safety position and a comfort position of the head of the seat occupant in the direction of displacement. A blocking device for blocking or minimising displacement of a first section of the head rest counter to the direction of displacement is provided. Said blocking device is asymmetrical in relation to a central plane of the head rest, said central plane extending essentially in a vertical or parallel manner in relation to the direction of displacement in the built-in position of the head rest and can be actuated by means an actuation element that is arranged symmetrically in relation to the central plane.

Abstract: The invention relates to a head read for a vehicle seat in which, in the event of an accident, at least one first section of the head rest that is oriented towards the head of the seat occupant can be displaced, due to the effect of a relative displacement of a second section of the head rest that is arranged essentially between the first section and the third section, from a working position into a safety position in the direction of the head of the seat occupant, in the direction of displacement. The relative movement of the sections is a rotation about an essentially parallel rotational axis in the direction of displacement. A mounting of the first section in relation to the second section is provided during the relative displacement about the rotational axis. The first section comprises a first bearing surface and the second section comprises a second bearing surface.

Abstract: A locking device and a headrest are disclosed. The locking device includes spring elements, which can be engaged in at least one locking position and the locking device can be displaced in relation to at least two retaining bars that have a large number of recesses. The spring elements co-operate with the recesses in such a way that the engagement of the spring elements in their locking position locks the locking device in relation to the retaining bars. According to the invention, the spring elements are configured in such as way that the retaining bars are locked by the mechanical fixing of the spring elements in their central zone or by exertion of a force on the spring elements in their central zone.

Abstract: A headrest guide sleeve for adjustably supporting a headrest pad is mounted in the back rest of a motor vehicle seat. The guide sleeve has a sleeve having a through bore for receiving the rod of the headrest, and a lever member rotatably fixed to an intermediate portion of the sleeve via a hinge mechanism. A biasing element is provided for biasing the lower end of the lever member toward the lower portion of the sleeve. The lever member includes a rib projecting into the through bore for engaging a notch formed on the rod. The upper end of the lever member is engaged with an actuating element. When the actuating element is actuated, the lever member is caused to rotate about the axis of the hinge mechanism against a biasing force of the biasing element thereby releasing the rib from the notch.
