Title: Vehicle safety belt retractors
IPC: H01F7/18
Filed: 1974-04-09
Abstract: 1445528 Inertia seat belt HONDA GIKEN KOGYO KK 9 April 1974 [10 April 1973] 15744/74 Heading A3V [Also in Division H1] An inertia-operated electric switching arrangement actuates a solenoid to lock the pawl and ratchet of a safety belt reel in the event of sudden stop. The switching arrangement comprising two switches, one operating in advance of the other, the first switch (which may be a transistor) having no moving contacts, and the second switch having a moving contact arm. In Fig. 2 the inertia mass 5 normally holds a bridging contact across contacts 7, and a second switch 10 is also normally held closed. When an acceleration greater than 0.5G is imposed on the inertia mass 5 the change in the pressure on contacts 7 is sensed by a load cell 8, the change causing an electronic circuit 9 to open switch 10 quickly, in advance of the contacts 7 opening. In this case de-energising the solenoid 4 locks the reel. The car ignition switch is indicated at 11, and a manual push-button by-pass switch is indicated at 12. Fig. 3 shows a resistance-wire strain-gauge 13 and a dummy load 14 for temperature compensation which detect the change in pressure on the contacts 7. The transistor 10 performs a switching function. Modifications include causing the solenoid to lock the reel when it is energised (Fig. 4, not shown), and including a second inertia mass which triggers at a lower acceleration (Fig. 6, not shown). A mechanical embodiment is shown in Fig. 9 where the mass 5 moves upwards against the pressure of a spring 21 to open contacts 27 before contacts 7.
