<p>The position of the upper mounting of a sash type automotive seat belt is made adjustable to provide optimum protection for vehicle occupants of differing heights. The adjustment may be done manually, or automatically by a controller which adjusts the seat belt mounting in response to fore-aft adjustment of the seats. The seat belt mounting lug is fixed by a bolt to a threaded block. The threaded block is carried on a vertical threaded rod which is supported at either end by a bracket inside the door pillar of the vehicle. The threaded rod may be rotated to raise or lower the seat belt mount, either by manual operation of a knurled knob fixed to the rod, or by an electric motor controlled by a potentiometer fixed under the seat to sense the seat position.</p> |
