ABSTRACT:
A webbing lock apparatus and assembly therefor is disclosed, wherein a relative rotation between a hook retainer and a wheel mass connected to a fly wheel causes a hook to move to contact a lock ring so that an inner portion of the ring comes into mesh with a portion of the hook thereby actuating a locking mechanism preventing a webbing of a belt to be unwound from an intermediate portion of a spool, upon the occurrence of an emergency condition. A web sensor spring is adjustable to set an elastic force that determines the duration of the locking operation. The apparatus simplifies the required assembly process and is easy to fabricate, thereby enhancing a product reliability, and cost competitiveness.
