Title: Webbing lock device for seat belt webbing retractor
Inventor: MORI SHINJI
IPC: B60R22/38
Filed: 1990-01-17
Abstract: In an emergency, the take up reel 20 rotates in the unwinding direction by a predetermined amount before being locked by lock wheel 38 engaging pawl lever 70, which is actuated by acceleration detector 68. If the reel moves less than the predetermined amount (eg on a bumpy road), tightening of the belt can occur by the paw being actuated and the belt reeling up on the ratchet of lock wheel 38. To prevent this, ratchet wheel 58 is provided adjacent lock wheel 38 and having ratchet teeth slightly proud of the teeth of the lock wheel (see Fig. 8 (E)). Wheel 58 is frictionally engaged with reel 20. In emergency conditions wheel 58 initially rotates until friction is overcome, thus allowing paw to ride right down into the teeth of lock wheel 38. Under small movements, the teeth of wheel 58 keep the paw clear of lock wheel 38, thus preventing unwanted tightening of the belt during recoil of the passenger on a bumpy road. …<IMAGE>…
