Abstract
A safety belt retractor has a belt storage spool and a spool rewind spring for biasing the spool in a belt rewind direction, means for reducing the tension applied to the belt when in use due to the bias of the rewind spring, means for activating such means for reducing in response to spool rotation in a predetermined manner and means for deactivating such means for reducing in response to spool rotation in a belt rewind direction of more than one full revolution of the spool under the influence of said reduced tension. The means for reducing the resultant effect of the rewind bias of the spring in an exemplary embodiment includes means for selectively applying a portion of the rewind torque of the spool rewind spring back on to the spool through a gearing arrangement in one version, and through a pulley means in another arrangement, in a belt unwinding direction to produce a reduced torque or 'comfort zone' effect upon the spool.
