Abstract
A head rest for the seat of an automotive vehicle is attached to a stay by means of a bolt which tightens a clamping clip onto the stay. The same bolt functions to hold the clip in place within the internal structure of the head rest. The engaging pressure of the clip can be adjusted by the bolt, and therefore, the precision with which the parts are formed does not need to be high allowing the head rest to be made inexpensively. By providing the clip in the interior of the head rest as opposed to an outside surface, it is possible to prevent injury to the vehicle occupants which might otherwise be caused by impacts on the clip or the bolt during an accident.
