ABSTRACT:
A safety belt retractor has a belt storage reel biased toward belt wound condition by conjugate return spring means comprising a first biasing spring connected to the reel for biasing said reel at a relatively low level for comfort zone torque rewind mode, a second biasing means for biasing the reel toward a belt wound condition independently of the first biasing means and means for releasably connecting the second biasing means to the reel whereby the reel is normally biased toward belt wound condition under the urging of both the first and second biasing means, but on releasing said second biasing means from said reel, the reel is biased to belt wound condition under the relatively low rewind torque of the first biasing means.
