A method for producing a cushion element for a vehicle seat, in which a component suitable for forming a three-dimensional separation zone is inserted in a tool, subsequently at least one first foamable mass is introduced into a first space of the tool. On foaming the mass, the component forms a three-dimensional separating element between a first foamed cushion region and a further space within the tool. The component is pressed against a counter-support in the tool during the forming to give a three-dimensional separating element. A suitable tool comprises an upper tool, a lower tool and a counter support for contacting a component taking on a three-dimensional shape. By introducing the three-dimensional mouldable shape into the tool and the subsequent forming thereof to give a three-dimensional separating element, complex formed regions with differing properties, in particular, differing degrees of hardness can be economically generated in a foamed cushion element.

Method for producing a cushion element and method and tool for the production thereto

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.

Head rest for a vehicle

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.

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.
