Abstract: A seat belt anchor mechanism has such a structure that a base plate connected to the side of a vehicle body is separated from its corresponding seat-side member or members subsequent to the occurrence of an emergency so as to permit free sliding of the associated set even after a load of at least a predetermined level has been applied to the webbing. The separation can be achieved by a combination of brackets which are normally kept in engagement but in the event of an emergency are readily disengaged. Alternatively, a shear pin may also be used. The seat belt anchor mechanism permits easy escape of an occupant from a vehicle even in the event of an emergency such as collision.

Abstract: Herein disclosed is an improved belt anchoring device which is incorporated with a slidable seat. The device uses a monolithic metal bracket for connecting a slide rail of the seat to a pin holder which is slidable on a toothed anchor stay fixed to the vehicle floor together with the seat. Upon application of abnormal impact load thereto through the seat belt, the bracket is forced to bend to permit locking engagement between the pin holder and the anchor stay thereby assuredly and safely dispersing the impact load to the vehicle body through the belt anchoring device.

Abstract: Apparatus for securing a seat belt to a longitudinally adjustable seat track mechanism of a motor vehicle. The seat belt is connected to one end of a lever, the lever being pivotal within the legs of a stepped U bracket, the step being secured to the movable track of the mechanism. The lever has a clamp end normally held out of engagement with a longitudinally extending tension member such as a wire cable secured to the vehicle body. The lever is held in its normal condition by either a shear pin or by the action of a helical spring. When a crash load is applied to the seat belt, the load causes the pin to shear (or when a spring is used--overcomes the spring bias) and the lever freed of restraint rotates to a position clamping the tension member against the base of the U bracket and preventing movement of the seat and seat belt relative to the vehicle body.

Abstract: A vehicle seat is mounted on the vehicle floor by a seat adjusting mechanism permitting fore and aft adjusting movement of the seat. A channel member is connected to the vehicle floor behind the seat and extends forwardly along the path of longitudinal seat adjustment movement. The channel member has opposed facing walls which are slidably engaged by a pair of wedge members having associated ramp surfaces. A seat belt is connected to the rearward one of the wedge members so that an occupant restraint load imposed upon the seat belt induces longitudinal forward movement of the rearward wedge member into locking engagement with the forward wedge member and the walls of the channel member so that the seat belt is fixed relative to the channel member and the occupant restraint load is transmitted through the channel member to the vehicle floor.

Abstract: Means are disclosed for adjusting the effective position from which the shoulder or diagonal belt of a vehicle seat belt system downwardly extends.
