Abstract

A stopper that stops both seat belt anchorages, namely, a seat belt anchorage for a side seat and a seat belt anchorage for a center seat from rotating relatively to each other is provided. Besides, a coupling portion of the seat belt anchorage for the center seat is arranged such that a force is applied to the seat belt anchorage for the center seat in such a direction as to restrain the seat belt anchorage for the side seat from rotating forward with respect to a vehicle. Accordingly, the seat belt anchorage for the side seat can be restrained from rotating forward with respect to the vehicle due to the seat belt anchorage for the center seat, and an inter-EAP distance can be restrained from becoming short.

Claims (30)

1. A seat belt device that is fixed to a vehicle body floor through use of a seat belt anchorage, wherein

the seat belt anchorage has a seat belt anchorage for a side seat and a seat belt anchorage for a center seat that are fastened together by a single bolt to the vehicle body floor,

the seat belt anchorage for the side seat and the seat belt anchorage for the center seat are equipped with fastening portions that are fastened to the vehicle body floor, and coupling portions that are coupled to seat belts, respectively, and are fastened together to the vehicle body floor at the fastening portions respectively,

at least one of the seat belt anchorage for the side seat and the seat belt anchorage for the center seat is provided with a stopper that stops both the seat belt anchorages from rotating and moving linearly relatively to each other by coming into contact with the other seat belt anchorage, and

the coupling portion of the seat belt anchorage for the center seat is arranged such that a force is applied to the seat belt anchorage for the center seat in such a direction as to restrain the seat belt anchorage for the side seat from rotating forward with respect to the vehicle, when a force is applied to both the seat belt anchorage for the side seat and the seat belt anchorage for the center seat forward with respect to the vehicle.

2. The seat belt device according to claim 1 , wherein

the coupling portion of the seat belt anchorage for the center seat is arranged such that a rotating force is applied to the seat belt anchorage for the center seat in a direction opposite to a rotating force that is applied to the seat belt anchorage for the side seat, or that the rotating force of the seat belt anchorage for the center seat becomes equal to zero, when the force is applied to both the seat belt anchorage for the side seat and the seat belt anchorage for the center seat forward with respect to the vehicle.

3. The seat belt device according to claim 1 , wherein

the coupling portion of the seat belt anchorage for the side seat is arranged closer to a center side in a width direction of the vehicle than the coupling portion of the seat belt anchorage for the center seat.

4. The seat belt device according to claim 1 , wherein

a fitting hole in which the stopper is fitted is formed through the other seat belt anchorage with which the stopper comes into contact, and

the seat belt anchorage for the side seat and the seat belt anchorage for the center seat are fastened together to the vehicle body floor, with the stopper fitted in the fitting hole.

5. The seat belt device according to claim 1 , wherein

each of the seat belt anchorage for the side seat and the seat belt anchorage for the center seat is provided with only the single fastening portion.

6. A seat belt device that is fixed to a vehicle body floor through use of a seat belt anchorage, wherein

the seat belt anchorage has a seat belt anchorage for a side seat and a seat belt anchorage for a center seat that are fastened together to the vehicle body floor,

the seat belt anchorage for the side seat and the seat belt anchorage for the center seat are equipped with fastening portions that are fastened to the vehicle body floor, and coupling portions that are coupled to seat belts, respectively, and are fastened together to the vehicle body floor at the fastening portions respectively,

at least one of the seat belt anchorage for the side seat and the seat belt anchorage for the center seat is provided with a stopper that stops both the seat belt anchorages from rotating relatively to each other by coming into contact with the other seat belt anchorage, and

the coupling portion of the seat belt anchorage for the center seat is arranged such that a force is applied to the seat belt anchorage for the center seat in such a direction as to restrain the seat belt anchorage for the side seat from rotating forward with respect to the vehicle, when a force is applied to both the seat belt anchorage for the side seat and the seat belt anchorage for the center seat forward with respect to the vehicle,

wherein a centerline passing through a center of the fastening portion and the coupling portion of the seat belt anchorage for the side seat intersects a centerline passing through a center of the fastening portion and the coupling portion of the seat belt anchorage for the center seat in a top view.

7. The seat belt device according to claim 6 , wherein

the coupling portion of the seat belt anchorage for the center seat is arranged such that a rotating force is applied to the seat belt anchorage for the center seat in a direction opposite to a rotating force that is applied to the seat belt anchorage for the side seat, or that the rotating force of the seat belt anchorage for the center seat becomes equal to zero, when the force is applied to both the seat belt anchorage for the side seat and the seat belt anchorage for the center seat forward with respect to the vehicle.

8. The seat belt device according to claim 6 , wherein

the coupling portion of the seat belt anchorage for the side seat is arranged closer to a center side in a width direction of the vehicle than the coupling portion of the seat belt anchorage for the center seat.

9. The seat belt device according to claim 6 , wherein

a fitting hole in which the stopper is fitted is formed through the other seat belt anchorage with which the stopper comes into contact, and

the seat belt anchorage for the side seat and the seat belt anchorage for the center seat are fastened together to the vehicle body floor, with the stopper fitted in the fitting hole.

10. The seat belt device according to claim 6 , wherein

each of the seat belt anchorage for the side seat and the seat belt anchorage for the center seat is provided with only the single fastening portion, and
