An inertia sensitive actuator especially adapted for use with a dual spool retractor for a motor vehicle seat belt system, The dual spool retractor includes shoulder belt and lap belt spool assemblies engaging with the shoulder belt and lap belt portions of the seat belt webbing, The dual spool retractor incorporates an inertia sensitive actuator having an excitation mass which is coupled with both of the retractor spool assemblies via linkages,

Inertia actuator for seat belt retractor

A device and method for tensioning a vehicle seatbelt are disclosed. The device has a motor, a pulley, a first cable, and a seatbelt buckle. The motor has a motor output for transferring rotational energy developed in the motor. The pulley is in communication with the motor output for receiving the rotational energy developed in the motor. The first cable has first and second ends. The first end is coupled to the pulley. The seatbelt buckle is coupled to the second end of the cable. The rotation of the pulley causes movement of the seatbelt buckle.
