Seat belt retractor

摘要

A retractor including a rotatable shaft including a coupling feature, a lock base having a recess, a spool configured to rotate about an axis of rotation to wind and unwind the seat belt, a longitudinal member, and a drive member. The spool includes a central bore that extends along the axis of rotation and is configured to receive a first portion of the shaft therein. The longitudinal member includes a longitudinal bore and a transverse bore that intersects with the longitudinal bore, the longitudinal bore being configured to receive a second portion of the shaft therein. The drive member includes a first portion passing through the transverse bore and a second portion disposed in the recess, the first portion including an engaging feature, where a load is transmitted between the shaft and drive member when the engaging feature is coupled to the coupling feature.
