Abstract

Improvements introduced in a safety belt retractor device having a belt storage reel, whose improvements, in the spool rewinding means, comprise the provision of: main rewind spring means and means for connecting it to said reel for loading normally said reel in a direction of rewinding the belt; means capable of being operated in response to the movement of said belt when it extends to a position of use to block the loading of said main spring on said reel; and second rewind spring means for loading said reel in said rewind direction when the loading of said main spring is blocked.
