Patent ID: 7597391

Claim:
An apparatus comprising: a seat back having an outer surface that selectively contacts a seat occupant; a head restraint extending from the seat back and having a head restraint portion that selectively contacts the seat occupant, wherein the head restraint portion is moveable between a forward position and a rearward position; and a head restraint control assembly positioned within the seat back and having an activator to transfer an actuation force in a first actuation event to the head restraint portion for initiating movement of the head restraint portion, said head restraint control assembly including: a lock mechanism for selectively restraining the headrest portion from moving from the forward position to the rearward position; and a lock mechanism resetting device operably coupled to at least a portion of the lock mechanism, wherein the head restraint portion will selectively move toward the occupant relative to the seat back when the occupant exerts a force on a portion of the head restraint control assembly, and wherein the lock mechanism resetting device will reset the lock mechanism after a time of about 300 milliseconds (ms) by converting at least a portion of kinetic energy generated in the first actuation event into a resetting energy.
