Abstract
A seatbelt retractor includes a frame and a spool rotatably supported by the frame. The spool has a rotational axis. The seatbelt retractor includes a ring selectively lockable with the spool. The seatbelt retractor includes a locking device operatively coupled between the spool and the ring to rotationally engage the spool with the ring in a locked position and rotationally disengage the spool from the ring in an unlocked position. The seatbelt retractor includes a linear actuator having a base and a pin. The base is fixed relative to the frame and the pin being moveable relative to the base and the frame toward and away from the ring along the rotational axis.
