ABSTRACT:
A safety belt retractor is disclosed of the type adapted for mounting in the door of a vehicle and operated by movement of a high inertia mass to lock up only under the influence of high lateral forces such as imposed in an emergency condition. During periods of door opening a superceding fulcrum point about which the high inertia member must rotate to lock up the retractor is imposed whereby undesired lock-up of the retractor during rapid opening of the vehicle door is virtually eliminated. The inhibiting action is directly tied to the door locking mechanism whereby almost instantaneous inhibition is applied upon opening of the vehicle door.
