Abstract
A seat belt retractor has a single spring arrangement for a dual belt system. The spring is connected between two drum members which are respectively connected to one seat belt and one member of an epicyclic gear mechanism. The other two members of the epicyclic gear mechanism are connected to the other seat belt and the other drum member, respectively. Extension of either or both seat belts results in the spring being transferred from one drum to the other resulting in a force differential between the drums. Retraction of the belt or belts is enforced by the spring returning to the as assembled position on the drums to relieve the force differential. The epicyclic gear mechanism is operable to drive one drum at a higher rate of speed than the other drum independently of which seat belt is extended.
