Patent DE-3926370-A1 (DE)
Inventor: OHLSSON JORGEN
IPC: B60R22/41
Filed: 1989-08-05
Abstract: A retractor reel for a vehicle safety belt has a rotatable shaft which automatically winds in the safety belt. Means responsive to the rate of belt withdrawal actuate a locking arrangement which locks the shaft. However, an arrangement senses the quantity of belt present on the reel and when a large amount of belt is present on the reel, the means responsive to the rate of belt withdrawal are dis-abled. This prevents the shaft from being inadvertently locked when the belt has been fully wound onto the reel 7. The sensing means comprises a lever 31 which, when a large amount of belt is on the reel, causes a member 41 to move axially and enable pins 44 to lock inertia weight 18 and follower 17 in position relative to toothed wheel 19. <IMAGE>
