ABSTRACT:
In a blocking device for a safety belt having a belt retractor, which carries a belt reel for winding and unwinding the safety belt and has a control wheel controlled in a safety belt-sensitive and/or vehicle-sensitive manner and a control plate controlled thereby for triggering blocking of the belt reel, a self-blocking action of the belt retractor is to be cancelled by a single pull on the safety belt. On the control plate a pilot pawl is supported, which is rotatable by the movement of the control plate and which, during the blocking sequence, before the latter reaches its disengaged position, holds the control plate securely in such an intermediate position that a subsequent relative movement between the control wheel and the control plate is possible. This results in the cancellation of the self-blocking action and the return of the relevant structural parts into their respective initial position.
