Abstract

A vehicle seat headrest with a carrier structure including at least one bar and a supporting member in a normally utilization position. In the event of an accident, the supporting member leaves the utilization position and assumes a crash position, in which the supporting member is located in front of the utilization position at least in the x-direction. An expandable container is disposed between the bar and the supporting member in a normally non-expanded state. A source of pressurized gas is connected to the container. A trigger device releases the gas in the event of an accident so that the expandable container is filled with gas and is in an expanded state so that the supporting member is in the crash position.
