Abstract: A vehicle safety apparatus (10) includes a seat (12) for an occupant of a vehicle. A length of belt webbing (42) is extensible about the occupant of the vehicle seat to restrain the occupant. The length of belt webbing has a portion (48) extending from an upper portion (24) of the seat back (20). A belt webbing engaging member (76) is mounted on the seat back (20) for guiding movement of the belt webbing (48) from the seat back. The safety apparatus includes means (120) for mounting the belt webbing engaging member (76) on the seat back (20) for movement relative to the seat back in a direction between the seat back inboard side (28) and the seat back outboard side (26). In a preferred embodiment, the belt webbing engaging member is a seat belt retractor spool (76). The retractor spool (76) is mounted in the frame (62) of a retractor (60) for rotation about an axis (82). Shoulder belt webbing (48) is wound on the spool (76).

Abstract: One end of the strap forming the safety belt is rigidly connected to a rear lower portion of the armature of the seating portion of the seat by a blockage mechanism. A shoulder keeper situated frontwardly with respect to the upper portion of the front face of the seat back provides for a sliding and guiding of a run of the safety belt passing above the passenger shoulder. An other end of the run of the safety belt is secured to an iron fitting fixed with one of the side flanges of the seating portion armature and forming a second fixation point. A keeper cooperating with a lock forms a third lower fixation point of the safety belt and is connected to the side flange opposite the second fixation point on the armature of the seating portion of the seat.

Abstract: A three-point safety belt system is provided which the upper deflection and fastening point for the belt strap cannot be arranged on the B-column of a vehicle body. So as not to interfere with the appearance of the vehicle body or with its lines but, yet obtain an optimal course of the belt strap in the event of a crash, the safety belt system has a displaceable belt point. This belt point is normally kept downward and will then be situated in the area of the window ledge or lower and can thus not be seen from the outside. In the event of a crash, the belt point displaces upward and thereby provides a belt strap course which ensures an optimal protection of the vehicle occupants.

The riser is configured to maintain an interlocked relationship with respect to the sliding load bracket throughout the entire range of longitudinal fore and aft seat adjustment. In addition, the seat belt buckle anchorage arrangement includes an elongated reinforcement bracket secured to the sliding load bracket for sliding longitudinal movement therewith and which is adapted to inhibit excessive pivotable excursions of the seat belt anchor.

Abstract: A seat adjustment latch, selectable at two different force levels, is attached to a slide adjustable seat in a motor vehicle equipped with a seat belt assembly, an inflatable air bag, and a knee restraint. The seat adjustment latch is interlocked with the seat belt assembly of the seat such that when the seat belt is unfastened, the seat adjustment latch is set to release the vehicle seat in the event of a rapid deceleration or impact to the vehicle above a predetermined level of severity. When the seat belt is fastened, the seat latch is set in its firmest possible retention setting and operates such that the inertia and kinetic energy forces of the seat and the occupant seated thereon will not move the seat forward in response to a severe frontal collision. In a preferred embodiment, the seat adjustment latch includes a shearing element configured as a tubular bolt for retaining the slide adjustable vehicle seat to the seat rails.
