Abstract

A seatbelt retractor inertial locking system for motor vehicle belt restraint systems. The inertial locking system incorporates features to reduce the influence of contaminants from causing unwanted locking of the associated retractor. The feature is in part provided by the positioning of a point contact between a ball mass and a locking lever. The inertia actuator forms the inertial ball mass nest surface which has a vented construction which permits the escape of contaminants and further contributes to reducing noise generated by contact between the ball mass and the nest surface.
