A head restraint for the occupant of a vehicle seat is disclosed, which restrains the forward and downward movement of the occupant's head when subjected to large deceleration forces. The restraint includes a strap assembly which encircles the back of the occupant's head and releasably connects to his helmet adjacent to each of his ears at two locations. A retaining strap is slidably connected by a loop to the strap assembly and extends behind the head to a retracting means fixed in the seat. The retracting means pulls the head back against the seat when the deceleration forces exceed a predetermined level, as during flight maneuvers. During normal flight conditions, the occupant is able to move his head freely from side to side as the strap assembly slides through the loop. Keywords: Patent applications. (KT)
