ABSTRACT:
A seat belt system (10) for restraining a vehicle occupant includes a retractor (18), a first locking tongue (40), a second locking tongue (46) and a buckle (20). The retractor (18) includes a spool (60) which is rotatable in a webbing winding direction and a webbing unwinding direction. The retractor (18) further includes a lock bar (70) which blocks rotation of the spool (60) in the webbing unwinding direction when the lock bar (70) is in a locking position. The first locking tongue (40) is connected with one length (26) of seat belt webbing (16). The second locking tongue (46) is connected with another length (28) of seat belt webbing (16). The buckle (20) has a locking mechanism (82, 90) for locking the first and second tongues (40) and (46) in a buckle (20). The seat belt system (10) further includes an actuator (130) for moving the lock bar (70 ) in the retractor (20) into the locking position in response to locking of the first and second tongues (40) and (46) in the buckle (20). The actuator (130) moves the lock bar (70) into the locking position only in response to locking of both the first and second tongues (40) and (46) in the buckle.
