  • Patent number: 4106721
    Abstract: A safety belt retractor, having a webbing storage means biased toward a webbing stored condition and associated safety belt webbing, is provided with latching means for preventing movement of the storage means toward a webbing stored condition upon protraction of the webbing to relieve tension in the webbing due to the bias of the storage means and additional means for providing a limited low tension travel of the webbing while the storage means is prevented from moving by the latching means. Means are supplied for deactivating the latching means upon protraction or retraction of the webbing beyond the limits of said limited low tension travel to provide for an automatic resetting of the latching means in different positions of use of the webbing and to allow for retraction of the webbing by the webbing storage means to said stored condition when the safety belt is released.
