Preloader apparatus

摘要

A preloader apparatus retracts, upon quick deceleration of a vehicle, a buckle apparatus with which a tongue plate for supporting a webbing is engaged so as to fasten the webbing onto an occupant of the vehicle. The preloader apparatus has a flexible wire connected to the buckle apparatus and used to retract the buckle apparatus and a supporting member which supports the wire so as to maintain a predetermined portion of the wire in the standing state and whose supporting function is canceled upon retraction of the buckle apparatus. Accordingly, the buckle apparatus can be maintained in a predetermined standing state.
