Claims

[Claims for Utility Model Registration] (1) A metal inertial pendulum that is supported in an enclosed state within a box and swings by sensing the acceleration/deceleration of the vehicle body; It consists of a movably pivoted lock lever and a cam wheel facing the other end of the lock lever and connected to the belt take-up shaft, and the inertial pendulum swings in accordance with a predetermined acceleration/deceleration, The emergency lock of the seat belt retractor is such that the lock lever is flipped up as a result of this swinging motion, and its swinging end engages with lock teeth formed on the outer periphery of the cam wheel to prevent rotation of the shaft. An emergency locking device for a seatbelt retractor, characterized in that the device is provided with means for regulating the operating range of the inertial pendulum or the locking lever. (2) The movement range regulating means includes a guide piece that is integrally hung below the swinging end of the lock lever, and a guide that is carved on the outer periphery of the box and that slidably guides the tip of the guide piece. 2. An emergency locking device for a seat belt retractor according to claim 1, wherein the emergency locking device comprises a groove. (3) The movement range regulating means consists of gate-shaped regulating pieces extending on both upper sides of the box,
2. An emergency locking device for a seatbelt retractor according to claim 1, wherein a locking lever is located at a lower portion of said regulating piece. (4) The emergency locking device for a seat belt retractor according to claim 3, wherein the regulating piece is fixed on both sides to mounting brackets integrally provided on both sides of the box. 4. An emergency locking device for a seatbelt retractor according to claim 3, wherein the emergency locking device extends integrally from both sides of the box. (6) The seat belt retractor according to claim 1, wherein the operating range regulating means is a holding mechanism provided on the inner bottom surface of the box and for holding the bottom of the inertial pendulum. Emergency locking device. (7) The emergency locking device for a seatbelt retractor according to claim 1, wherein the actuation range regulating means comprises a regulating piece provided at the top opening of the box and regulating the inertial pendulum from jumping out. .
