PROBLEM TO BE SOLVED: To optimize a disposing form so as to be capable of retaining a retractor exactly in forming a seat belt device for the central seat of a vehicle rear seat into three-point type. SOLUTION: A bracket 1 for fitting retractors 41, 42 to a vehicle is constituted of a belt line part 1a and a rear pillar part 1b. A webbing 41a is extended forward by disposing a first retractor at the front part position of the belt line part, a webbing 42a is extended toward an anchor 43 by disposing a second retractor at the rear part position of the belt line part, and the extending direction of the webbing is changed front-downward by the anchor. If loads F1, F2, F3 acting on the retractor and an anchor fitting part are combined, the vertical loads of the second retractor and the anchor are offset by each other. It is thus possible to decrease the load acting on the jointing part between the bracket and the vehicle body and reinforce the bracket effectively, thereby retaining a plurality of retractors positively. |
