The invention relates to a method for assembling a crash-active head support () of a vehicle seat, whereby the structure of the head support () is initially assembled from a rear and a front bearing shell and is then upholstered. The rear bearing shell () and the front bearing shell () are equipped with components () and then the equipped bearing shells () are rigidly connected together. An impact element () is coupled thereto thus forming a quadruple joint.

Method for assembling a crash-active head support

In the case of a vehicle seat, in particular a motor vehicle seat, with a seat part structure (), a seat cushion () positioned on the seat part structure () and an antisubmarining ramp () effective at the latest at the beginning of a crash, the antisubmarining ramp () is movable in a recess () of the seat cushion ().

Vehicle seat with antisubmarining ramp

In a headrest () for a vehicle seat, having a carrier (), at least one upper and lower linkage () linked to the carrier (), which can be pivoted around horizontal axles (), a impact element () linked to the linkages () which forms at least one four-bar linkage () with the linkages () and the carrier (), and an energy storage device (), the energy storage device () driving the four-bar linkage () in the event of a crash, so that the impact element () comes out forward from an original position into a crash position that is locked against a backward movement by a crash lock, the upper linkage () and the lower linkage () are unparallel with respect to one another.
