Abstract
A seat belt retractor (40) associated with a seat (10) includes a spool (106) about which seat belt webbing (42) is wound. The spool (106) is supported for rotation in a belt withdrawal direction and in an opposite belt retraction direction. A vehicle sensitive sensor (190) is responsive to at least one sensed vehicle condition for preventing rotation of the spool (106) in the belt withdrawal direction. A first mechanism (206) is responsive to a first condition for disabling the vehicle sensitive sensor (190). A second mechanism (294) is responsive to a second, different condition for preventing rotation of the spool (106) in the belt withdrawal direction. The second condition is a condition of the associated seat (10). In one embodiment, a third mechanism (400) is responsive to the first condition for allowing rotation of the spool (106) in the belt withdrawal direction.
