Abstract: A belt buckle feeder for a vehicle seat belt system includes a spindle drive and a belt buckle (12) mounted on a spindle (14) of the spindle drive, the belt buckle being movable in height via a spindle nut (26) located on the spindle (14). A safety mechanism comprising at least one locking element (44) is provided which is configured so that the locking element (44) enters into force fit and/or form fit with the spindle (14), when a predetermined force threshold is exceeded, and introduces force acting on the belt buckle (12) in the extending direction (R) of the spindle (14) into a mounting point fixed to the vehicle white bypassing the spindle drive.

Abstract: A belt buckle for vehicle safety belts has a load bearing frame and a locking mechanism thereon. A housing encloses the frame and has an insertion slot for an insert tongue acting in conjunction with the locking mechanism. To eliminate any extraneous matter that has entered into the housing through the insertion slot, a channel leads from the insertion slot through the housing and out of the housing, forming a guide for gravity assisted movement of such extraneous matter out of the housing.

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 (42) 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).
