Speed-sensitive wire extraction control device and restraint device utilizing the same

A speed-sensitive wire extraction control device comprising:

• a casing having a wire inlet/outlet parts through which wires passes, and a stopper part protruding inward;
• a bobbin disposed inside the casing and having wires wound on its outer surface;
• an operating body connected to rotate together with the bobbin;
• a first operating member and a second operating member, one end of each being rotatably connected to the operating body and the other end being a free end which operates to be adjacent to or spaced apart from the inner wall of the casing;
• a seating part formed on the operating body to accommodate the first operating member and the second operating member;
• a first elastic restoring member and a second elastic restoring member, one end of each elastic restoring member supported by a mounting part and the other end of each elastic restoring member connected to one side of the corresponding operating member;
• wherein the free ends of the first operating member and the second operating member are caught by the stopper part when the wire is extracted at a speed exceeding a set threshold, thereby restricting the bobbin from unwinding.
