Abstract

1360854 Vehicle safety harness JOSEPH LUCAS (INDUSTRIES) Lid 10 April 1972 [13 April 1971] 9268/71 Heading A3V [Also in Division H1] An electric switch is actuated by movement of a vehicle seat belt 14 Fig. 2 passed through an aperture 13 in the switch and having an abutment hole 24 engageable with a resiliently biassed moveable contact 18 of the switch to disengage it from a fixed contact 20 and thereby monitor that the belt 14 has been withdrawn from its reel to its position in use. In one embodiment the contact 18 comprises a bent wire having a loop 17 Fig. 1 engageable in the hole 24 but moveable by snap action between a stable "on" position and a stable "off" position against stop 21. A terminal connection is provided by a plate 23 in the base 12 engaged by the contact 18. In a modification the moveable contact comprises a flat plate contact 123 Fig. 4 which bridges a pair of fixed contacts 121 and is resiliently urged towards the belt 114 by an arcuate yieldable casing portion 124. The upper and lower portions 110 and 111 of the casing are folded together at a flexible connecting portion 112 and are clipped together by flexible interengaging lips 117, 118. A monitoring circuit Fig. 3 operates a warning lamp 31 and an alarm 32 if the driver's or passenger's seat belt switches 25, 26 are still closed when the ignition switch 28 and a gear lever operated switch 27 are also closed. A further switch 30 operated by the weight of a person in the . passenger seat renders the switch 26 inoperative when the passenger seat is unoccupied.
