PURPOSE:To selectively use seat belts in either a three-point system or a four- point system by selectively fitting shoulder belt anchors in buckles at the both sides of a seat or the buckles' of a lap belt anchor, and furthermore, selectively fitting a hanging fixture into buckles at the inner side of a cabin or in buckles in the rear section of the seat. CONSTITUTION:When seat belts are put on by means of a three point system, the anchor 9 of a lap belt 7 pulled out of a first retractor 5 is fitted in a buckle 11. And the hanging fixture 25 of a shoulder belt 23 is fitted in a buckle 27. Furthermore, an anchor 29 is fixed onto the webbing 19 of a second retractor 17 while being fixed at the one end section of the shoulder belt 23 so as to be fitted in a buckle 21, and similarly a shoulder belt anchor 31 fixed at the other end section is fitted in the anchor 9. On the other hand, the seat belts are put on by means of a four point system, the respective shoulder belt anchors 29 and 31 are fitted in a slide type buckle 15, and the hanging fixture 25 is concurrently fitted in the buckle 37 of a webbing 35 pulled out of a third retractor 33. |
