Patent number: 6631865Abstract: A seat belt retractor operates in two distinct modes: a first, Emergency Locking Retractor (ELR), mode; and a second, Automatic Locking Retractor (ALR), mode. A toothed ratchet wheel is mounted to rotate with a spool that is biased in a seat belt webbing rewinding direction. A sensor detects an emergency condition of the vehicle. A vehicle acceleration sensor lever responsive to the sensor engages the ratchet wheel in the event of an emergency condition. The vehicle acceleration sensor lever performs two functions: it locks the retractor when the sensor detects accelerations and decelerations greater than a predetermined magnitude and it also prevents rotation of the spool in the seat belt webbing pay-out direction when operating in its second mode. A cam connected to the spool via a step-down gearing arrangement acts as a switch.Type: GrantFiled: November 1, 2001Date of Patent: October 14, 2003Assignee: Breed Automotive Technology, Inc.Inventor: Martyn Palliser
