ABSTRACT:
An automatic locking retractor suitable for use in a vehicle seat belt includes locking means which is composed of a latch plate rotatable as a unitary member with a take-up spindle and a lock member engageable with the latch plate to prevent the rotation of the take-up spindle. The engagement between the latch plate and lock member is controlled by a cam member or disk of a simple structure. Making use of magnetism, the cam member or disk is kept in a cooperative relation with the latch plate or take-up spindle. The automatic locking retractor requires fewer parts, and hence permits easy parts handling and facilitates its assembly work. It is also compact.
