ABSTRACT:
The vehicle-sensitive inertia mass of a control mechanism for a pretensioner in a safety belt restraining system is secured in a safety position by a blocking means engaging on the inertia mass to inhibit operation of said pretensioner. A sensing pin senses the approach of the housing of the control mechanism to a part of the vehicle bodywork in the mounting of the housing on said part of the vehicle bodywork and converts said approach to an actuating travel which causes the blocking means to release the inertia mass.
