Abstract
A seat belt retractor has a web sensor with an inertia member, a locking pawl and a lock cup. The inertia member is eccentrically pivotally mounted to the lock cup. The locking pawl is integrally formed with the inertia member. The lock cup has a set of radially inwardly pointing teeth for engaging with the locking pawl. The shape and profile of the locking pawl complements the shape of the teeth. The web sensor aids in resisting jamming of the seat belt retractor.
