ABSTRACT:
Disclosed herein is an automatic locking retractor suitable for use in vehicle seat belt. The retractor is constructed of a take-up spindle, a cog wheel mounted integrally with the spindle, a latch gear integrally rotatable with the cog wheel, a lock lever normally kept in engagement with the cog wheel, a control member and sensor means. The control member is normally biased to a position where it is engageable with the latch gear. The control member can assume a first and second working positions when the take-up spindle is rotated respectively in the pulling-out and winding directions of the webbing. In the first and second working positions, the control member is in contact with the path of rotation of circumference of the latch gear. The control member holds the lock lever in a position where the lock lever permits free rotation of the cog wheel when the webbing has been pulled out and the control member has moved toward the first working position. The control member, on the other hand, permits the lock lever to engage with the cog wheel when the control member has moved toward the second working position. The retractor features fail-free control of the movement of the lock lever owing to the provision of the control member.
