摘要:
A powered headrest operating system includes a headrest connected to a seatback frame using rotational pins. An actuation mechanism rotatably connected to the seatback frame has a power actuated member connected to the headrest operating between retracted and extended positions to rotate the headrest from a fully retracted to a forward rotated position about an axis of rotation of the rotational pins. A release system rotatably connecting the headrest to the actuation mechanism retains the headrest at any forward rotated position while the actuation mechanism returns the power actuated member from the extended to the retracted positions if the headrest encounters an object blocking return to the retracted position. A biasing member connected to the seatback frame and the headrest creating a biasing force during headrest rotation away from the retracted position operates without actuation mechanism operating force to bias the headrest frame assembly toward the retracted position.
