Abstract

An emergency locking seat belt retractor includes an inertia sensor, a trip lever responsive to the sensor and a driver finger 71 on the trip lever. A separate locking pawl 4 engageable with a ratchet wheel 3 is provided in the retractor and includes a pin which is normally spaced from the driver finger 71 by a distance 'a'. Sudden vehicle deceleration causes sensor ball 6 to move so pivoting lever 7 to position tip 72 in the path of the teeth of plastic trip wheel 8, which deceleration also sets in motion by unwinding of the belt. Finger 71 now contacts pin 9 and so rotation of wheel 8 is transmitted via this pin 9 to locking pawl 4, so that its teeth 41 engage ratchet wheel 3 to halt its rotation and so lock the seat belt. An acceleration sensor may additionally be provided, acting directly on trip lever 7.
