POWERED RETRACTING HEAD RESTRAINT

摘要

A seat assembly for supporting an occupant includes a seat back and a seat cushion. The seat back extends between a lower end coupled to the seat cushion and an opposite upper end. A head restraint is slidably coupled to the upper end of the seat back for vertical movement between a use position spaced apart from the upper end of the seat back and a stowed position adjacent the upper end of the seat back. A mechanism is operatively coupled to the head restraint for automatically moving the head restraint to the use position in response to detecting the occupant on the seat assembly and to the stowed position in response to detecting the absence of the occupant on the seat assembly.
