Claims (1)

[Claims for Utility Model Registration] (1) A webbing lock device that prevents the longitudinal movement of occupant restraint webbing in the event of a vehicle emergency, the webbing being configured such that one end of the webbing is wound up so that rotation is locked in the event of a vehicle emergency. a webbing winding part having a webbing winding shaft, a winding roller that winds an intermediate portion of the webbing unwound from the webbing winding shaft, and the webbing that is actuated by tension acting on the webbing in the event of a vehicle emergency. A movable pressing member that presses the webbing by the action of a winding portion, and a fixing member that is fixed at a position facing the movable pressing member to sandwich the webbing between the movable pressing member and the movable pressing member. A webbing lock device comprising a pressing member. (2) The webbing winding portion includes a movable frame biased by a spring in a direction away from the movable pressing member, and the winding roller pivotally supported by the movable frame, and the webbing winding portion is provided with The webbing lock device according to claim 1, wherein the movable frame presses the movable pressing member by a tension applied to the webbing lock device. (3) The winding roller is pivotably supported by the movable frame so that the winding roller can move axially, and the winding roller moves within the movable frame due to the tension acting on the webbing in the event of a vehicle emergency, and the movable frame moves. The webbing lock device according to claim (2) of the utility model registration, wherein the webbing lock device is configured to prevent the rotation of the winding roller by coming into contact with a roller stopper fixed to the webbing lock device. (4) A lever in which the webbing winding portion is biased by a spring in a direction away from the fixed pressing member, the winding roller pivotally supported by the lever, and the movable pressing member fixed to the lever. Claim (1) of the registered utility model, wherein the lever is rotated by the tension applied to the webbing in the event of a vehicle emergency, and the movable pressing member is pressed against the fixed pressing member. The webbing lock device described in . (5) The scope of the utility model registration claim, wherein the winding roller is formed of a gear roller, and as the lever rotates, a gear lock member engages with the gear roller to prevent rotation of the gear roller. The webbing lock device described in paragraph (4). (6) The movable pressing member comprises a pressing lever having extensions on both sides of the rotating shaft, and the webbing winding part is spring-biased in a direction away from one end of the pressing lever, and the webbing is movable around the shaft. The webbing is comprised of a hanging roller, and when the wrapping roller presses one end of the pressing lever due to the tension acting on the webbing in the event of a vehicle emergency, the other end of the pressing lever is pressed against the fixed pressing member. A webbing lock device according to claim (1) of the claimed utility model registration.
