Abstract
A seat belt retractor of the inertia type comprises a rotatable shaft with a cam-surface driven thereby. A locking element movable on the cam surface is positively displaced by a control element fitted in a recess thereof and acting from an inertia element. The locking element, when driven by the inertia member, engages with the teeth on an annular locking ring to stop retraction of the seat belt attached to the shaft. The inertia element may be spring preloaded and a locking wheel may be provided to provide alternative locking torque for the inertia element when the car assumes a roll-over condition in which the seat belt would not ordinarily retract quickly.
