ABSTRACT:
An emergency lock retractor is equipped with locking means to be actuated in the event of emergency. The locking means includes stationary locking teeth, an interlocking member provided displaceable between a first position where the interlocking member is out of engagement with the locking teeth and an second position where the interlocking member is brought into engagement with the locking teeth and take-up spindle so as to restrain any further rotation of the take-up spindle, a spring member adapted normally to cause the interlocking member to rotate together with the take-up spindle and to bias the interlocking member toward the first position while holding the interlocking member out of engagement with the take-up spindle, a locking member for causing the interlocking member to shift from the first position to the second position; and means permitting the rotation of the locking member in association with the take-up spindle in the event of emergency. Owing to the provision of the means permitting forced rotation of the take-up spindle in the event of emergency, all the parts are kept free from undue loads.
