<p>An adjustable shoulder anchorage for a vehicle safety belt has a guideway (2; 102) along which a carriage (4; 104) supporting a running loop for the belt can be moved between selected positions. The carriage position is sensed by microswitches (34,35) co-operating with guideway formations (40, 41, 42) and is indicated by a display device (50) at the vehicle dashboard. In another arrangement, the carriage movement is effected by an electric motor (160) driving a screw-threaded shaft (162) received in a nut secured to the carriage. Carriage position is sensed and displayed as before and provision may be made for microprocessor control, with facilities for storing signals representing preferred carriage positions.</p> |
