Electromechanical retractable head restraint

摘要

A seat assembly comprises a seat cushion and a seat back having a bottom portion coupled to the seat cushion and an opposite top portion. A head restraint is coupled to the seat back for movement between a stowed position adjacent the top portion of the seat back and a deployed position spaced above the top portion of the seat back. A cable carriage is coupled to the seat back for actuation along a longitudinal axis between a home position and a lift position. A cable extends between a first end coupled to the head restraint and a second end coupled to the cable carriage for moving the head restraint between the stowed position and the deployed position in response to actuation of the cable carriage between the home position and the lift position.

1. A seat assembly comprising:
a seat cushion; a seat back having a bottom portion coupled to said seat cushion and an opposite top portion; a head restraint operatively coupled to said seat back for movement between a stowed position adjacent said top portion of said seat back and a deployed position spaced above said top portion of said seat back; a cable carriage operatively coupled to said seat back for actuation along a longitudinal axis between a home position and a lift position; and a cable extending between a first end operatively coupled to said head restraint and a second end fixedly coupled to said seat back, said cable carriage operatively coupled to said cable between said first and second ends for changing the effective length of said cable upon said actuation thereof along said longitudinal axis for moving said head restraint between said stowed position and said deployed position in response to actuation of said cable carriage between said home position and said lift position.
