Abstract:
    A buckle for vehicle safety belt systems provided with a pretensioner engaging the buckle, is prevented by a locking pawl (42) from unintentional opening at the beginning and at the end of a pretensioning stroke. By the effect of its mass inertia at the start of the pretensioning stroke an inertial body moves the locking pawl into a locking position in which the release button (30) is prevented from moving in a direction relative to the base in the pretensioning direction (R). Due to the location of its center of gravity relative to its mounting position the locking pawl (42) at the end of the pretensioning stroke remains in the locking position and is decoupled from the inertial body (56).
