locking mechanism and its actuating METHOD

The locking mechanism (1200) comprises an elastic yarn (404) supported adjacent its first end and its second end by a support structure (406). The locking mechanism also includes one or more hooks which have outer cam surfaces and in engagement with the thread coming openings. To engage the locking mechanism, the spring wire is pushed against the outer surfaces of cam deflecting the elastic yarn and allowing the latter to fall back resiliently in engagement apertures came with the wire. To disengage the latching mechanism, it deflects the elastic yarn pushing means (408) for actuating movable guide which is in engagement with so as to release the yarn thread (404) vis-a-vis openings hooks ( 218).
