The relates to a sensor for activating a vehicle-sensitive locking mechanism of a belt retractor, comprising an inertia body, a bearing supporting the inertia body, a release element which can be moved out of an idle position by movement of the inertia body so as to activate the vehicle occupant restraint system, wherein the inertia body can be pivoted about a stationary point of rotation.

Provided is a vehicle body rear structure including: a rear roof rail extending in a vehicle width direction and being attached with a retractor for a seat belt; a bracket which is connected to the rear roof rail, so that the retractor is arranged between the bracket and the rear roof rail, and defines an opening portion at an end portion in the vehicle width direction thereof with the rear roof rail; and an extension which connects an end portion in the vehicle width direction of at least one of a top surface and a rear surface of the bracket to a front wall of the rear roof rail. The rear roof rail includes a protruding portion which protrudes frontward to have the retractor arranged therein, and the front wall extending in a vertical direction at a front side of a vehicle body.

A seat belt take-up control system includes: a first belt-take-up unit mounted at a child seat, the first belt-take-up unit taking up a seat belt of a vehicle seat and applying a predetermined tension at a time of fastening the seat belt; a belt lock unit that prevents pulling out of the seat belt in a state which the seat belt has been taken up by the first belt-take-up unit; and an second belt-take-up unit that, in a state in which pulling out of the seat belt has been locked by the belt lock unit, takes up the seat belt and applies a predetermined tension after the seat belt is fastened in at least one of a case in which pulling out of the seat belt is detected or a case in which a predetermined period of time has elapsed.

A self-locking seat belt retractor includes a blocking system for a seat belt winding shaft that is actuated in an at least vehicle-sensitive manner, in which, in the event of triggering, a sensor mass mounted in a vehicle-sensitive manner moves a locking lever with its engagement tip into a trigger position in engagement with the toothing of a control disk, as the result of which the control disk in its joint rotational motion with the belt winding shaft is stopped and the blocking system is activated. The sensor mass is situated in a support part on a contact surface, and when vehicle accelerations occur the sensor mass in the support part is movable on the contact surface by inertial control from a neutral position into the trigger position. The support part together with the sensor mass situated therein is situated in a housing that includes the control disk. The housing with the support part and the sensor mass situated therein is fixable on the seat belt retractor in various rotational angle positions with respect to the control disk.

A motor vehicle belt restraint system combining a three-point active seatbelt system with a two-point seatbelt system. The webbing of the three-point seatbelt is allowed to slide through a latch plate releasably attached to a seatbelt buckle. The webbing of the two-point belt system is affixed to the latch plate. When in use, the belt systems combine to provide two lap belt segments extending across the lower torso of a vehicle seat occupant with a single diagonal shoulder belt section. Additional embodiments incorporate the use of an anchor mechanism for the three-point belt system having additional capabilities including a webbing release and a load limiting function. Further embodiments provide different arrangements for the two lap belt sections.
