Abstract
A head restraint assembly is disclosed. The head restraint assembly includes a frame. A shaft is coupled to the frame and is rotatable relative to the frame. An arm is coupled to the frame and is rotatable relative to the frame. The arm is rotatable to a lowered position and a raised position. A pawl is coupled to the shaft and is rotatable with the shaft about the shaft axis to an engaged position in which rotation of the arm from the raised position to the lowered position is prevented. The pawl is rotatable with the shaft to a released position in which rotation of the arm from the raised position to the lowered position is permitted. An actuator having an electric motor and a drive plunger rotates the shaft to move the pawl to the released position.
Claims29
A head restraint assembly comprising:
- a frame;
- a shaft coupled to the frame and rotatable relative to the frame about a shaft axis;
- an arm coupled to the frame and rotatable relative to the frame about an arm axis to at least a lowered position and a raised position with the arm axis spaced from the shaft axis;
- a pawl coupled to the shaft and rotatable with the shaft about the shaft axis to an engaged position in which rotation of the arm from the raised position to the lowered position is prevented and to a released position in which rotation of the arm from the raised position to the lowered position is permitted;
- and
- an actuator being connected directly to the frame and having an electric motor and a drive plunger, with actuation of the drive plunger rotating the shaft to move the pawl to the released position.

A method of operating a head restraint assembly having a frame, a shaft rotatable relative to the frame, an arm rotatable relative to the frame, a pawl rotatable relative to the frame, and an actuator coupled to the frame and having an electric motor and a drive plunger, the method comprising the steps of:
- moving the drive plunger with the electric motor from a retracted position to an extended position to rotate the shaft about a shaft axis, and
- rotating the pawl about the shaft axis to a released position to permit movement of the arm from a raised position to a lowered position.
