2. Description of the Related Art A three-point seat belt, which is applied to many vehicles, is composed of a portion around which a seated person is wrapped around the seat and a portion where the seat is draped, as is well known, and is supported at three points. It is like this. Specifically, as shown in FIG. 7, the retractor 1 assembled to the pillar 101 of the vehicle body
The waving 103 fed from 02 is the pillar 1
01 is inserted into a shoulder anchor 104 fixed to the upper part of the 01, and the end is fixed to an anchor plate 105 provided below the shoulder anchor 104. A tongue 107 that can be engaged with and disengaged from a buckle 106 fixed to the floor is mounted on the waving 103 between the shoulder anchor 104 and the anchor plate 105. The waving 103 between the anchor plate 105 and the tongue 107 holds the waist of the seated person H, and the waving 103 between the shoulder anchor 104 and the tongue 107 holds the seated person H from the waist to the shoulder. It is fixed at 108. This ensures that the seated person H is fixed to the seat 108 even in the event of a collision.

In the three-point seat belt having the above-mentioned structure, there is a problem that the fitting property of the waving 103 to the seated person H may not be good depending on the seated state. That is, as shown in FIG.
In the reclining state in which A is tilted, the upper half of the seated person H is largely inclined rearward along the waving 103 between the shoulder anchor 104 and the tongue 107, so that the fitting property of the waving 103 is deteriorated and the waving at the time of collision occurs. Since the shoulder is removed from 103, the seated person H cannot be fixed to the seat 108. Also,
This is also inconvenient when the seated person H is a short person such as a child. That is, as shown in FIG. 9, the waving 103 between the shoulder anchor 104 and the tongue 107 may come into contact with the neck or face of the seated person H or may be detached from the body. In such a state, not only the original function of the seat belt cannot be exerted, but it is also very dangerous in a collision.
