Abstract

A vehicle seat (10) with a back rest (12) and with an adjustable head rest (15) having a supporting surface (16) which the head of the vehicle occupant can touch in the case of restraint is characterized in that the head rest (16) has an expansion device which increases the size of the supporting surface (16) of the head rest (15) in the case of restraint. Furthermore, the head rest (15) is vertically adjusted in relation to the back rest (12) at least when the head rest (15) is arranged so close to the back rest (12) that the back rest (12) would prevent a complete increase in size of the supporting surface (16).
