Abstract
A seatbelt retractor is disclosed. The seatbelt retractor includes a frame, a spindle, and a torsion member. The frame is attached to a structural member of a vehicle. The spindle is rotatably supported in the frame. The spindle includes a slot for accommodating a seatbelt webbing. The torsion member is coupled to the spindle, and the torsion member has a first engagement end, a second engagement end and an intermediate engagement portion disposed between the first and second engagement ends. The intermediate engagement portion includes an engagement portion and a non-engagement portion, wherein the engagement portion couples the torsion member to the spindle and the non-engagement portion is proximate the seatbelt webbing and allows seatbelt webbing to pass through the slot without interference.
