Abstract
A seat belt retractor has a spool for carrying seat belt webbing rotatably mounted about a longitudinal axle and biased in a seat belt webbing rewinding direction. A toothed ratchet wheel is mounted to rotate with the spool. A sensor is provided for detecting an emergency condition, and a vehicle acceleration sensor lever is responsive to the sensor to engage the ratchet wheel in an emergency. The retractor can operate in a first, emergency locking mode in which the spool is not locked and can rotate to pay-out and to rewind seat belt webbing. In a second, automatic locking mode the spool is locked against pay-out of the seat belt webbing. A switching means has a subassembly attached to an end of the seat belt retractors. The subassembly has an axially directed spring to reduce axial spacing between the housing, an eccentric cam and axially adjacent disks.
