<p><P>PROBLEM TO BE SOLVED: To simply carry out operation of regulating a coupling position of a belt tightening lock member for such as a tang and a buckle to a seat belt while enabling a passenger to exactly corresponding to the operation. <P>SOLUTION: A pressed member 11a<SB>3</SB>of a clamp member 11a is pressed by specified pressing force against energizing force of a torsion spring 13, so that the clamp member 11a is rotated in a clockwise direction to release pinching of the seat belt 3 due to cooperation with a buckle main body 9a, and the seat belt 3 is released to be relatively movable to the buckle 9. By releasing pressing of the pressed member 11a<SB>3</SB>, the clamp member 11a is rotated in a counterclockwise direction by the energizing force of the torsion spring 13, and the seat belt 3 is pinched (clamped) between a surface roughness pinching surface 11a<SB>2</SB>of the clamp member 11a and a surface roughness pinching surface 9a<SB>1</SB>of the buckle main body 9a by cooperation of these pinching surfaces. The seat belt 3 does not relatively move to the buckle 9, and regulates a position of the buckle 9 to the seat belt 3. <P>COPYRIGHT: (C)2004,JPO</p> |
