BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure mainly applied to a seatbelt retractor of a rear seat of a vehicle, and more specifically, to mounting of a seatbelt retractor provided below a parcel shelf at the rear of the vehicle. Regarding the structure.

2. Description of the Related Art Conventionally, when a retractor is provided below a parcel shelf, an upper bracket joined to the lower surface of the parcel shelf and a lower bracket located below the upper bracket are fixedly mounted on the vehicle body. While attaching the retractor to the upper bracket, screw the anchor bolt through the parcel shelf to the upper bracket, pull out the seat belt drawn out from the retractor upward through the window opened in the parcel shelf, and attach the seat belt to the anchor bolt. I am trying to insert it in the ring.

[0003]

When the seat belt is locked by the retractor, an upward pulling force acts on the lower bracket through the retractor. And, in the above-mentioned conventional example, a reinforcing member is welded to the fixing portion of the lower bracket to the vehicle body so as to withstand this tensile force, but this takes time and effort for assembling the vehicle body, which causes a cost increase. Has become. SUMMARY OF THE INVENTION In view of the above points, the present invention has an object to secure a mounting strength of a retractor with a simple structure.

Means for Solving the Problems In order to solve the above problems,
The present invention is a seatbelt retractor mounting structure provided below a parcel shelf at the rear of a vehicle, including a bracket joined to the lower surface of the parcel shelf,
An anchor bolt is screwed to the bracket through the parcel shelf, the seat belt drawn out from the retractor is pulled out upward through the transparent window opened in the parcel shelf, and the seat belt is inserted into the anchor ring attached to the anchor bolt. The hanging portion extending downward is formed on the bracket, the retractor is attached to the hanging portion, and the retractor is arranged below the parcel shelf in a cantilever state.

When the seat belt is locked, an upward thrust force acts on the bracket through the retractor, but at the same time, a downward pulling force acts through the anchor bolt, and this pulling force causes the upward thrust force. The thrust forces are offset, and the joint between the bracket and parcel shelf is not overpowered. Therefore, it is possible to secure the mounting strength of the retractor without special reinforcement, and it is possible to significantly reduce the cost in combination with the fact that the conventional lower bracket becomes unnecessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, the present invention is applied to a structure for mounting a retractor 3 of a seat belt 2 for a rear seat 1 of an automobile, in which a retractor 3 is provided below a parcel shelf 4 at the rear of the vehicle. It is provided.

A bracket 5 having a hanging portion 5a extending downward is joined to the lower surface of the parcel shelf 4 by spot welding or the like at a bent portion 5b at the upper end. Then, the nut 5c is welded to the lower surface of the bent portion 5b, and the anchor bolt 6 is passed through the parcel shelf 4 and the nut 5c.
An anchor ring 7 attached to an anchor bolt 6 is pulled out upwardly through the through window 4a formed in the parcel shelf 4, and the seat belt 2 which is screwed to the c and is led out from the retractor 3 is pulled out.
The seat belt 2 is inserted through. In this embodiment, the cover 8 covering the transparent window 4a is attached to the parcel shelf 4 by the anchor bolts 6, and the seat belt 2 is inserted into the anchor ring 7 through the guide hole 8a formed in the cover 8. In the figure, 9 is a rear tray provided on the parcel shelf 4.

The retractor 3 includes a hanging portion 5 of the bracket 5.
It is attached to the front surface of a by means of a fixing bolt 10 that is screwed onto a nut 5d welded to the rear surface of the lower end of the hanging portion 5a, and thus the retractor 3 is provided below the parcel shelf 4.
Are placed in a cantilevered state. When tightening the retractor 3, the retractor 3 is provided with a claw piece 3a that engages with an engaging hole 5e formed in the hanging portion 5a of the bracket 5 so that the retractor 3 does not rotate with the rotation of the fixing bolt 10. It is formed to prevent the retractor 3 from rotating.

When the seat belt 2 is locked, the bracket 5
Upward thrust force acts on the anchor ring 7 and the anchor bolt 6 via the retractor 3.
This is offset by the downward pulling force acting via the and, and the joint between the bracket 5 and the parcel shelf 4 is not overpowered. Bending flanges 5f and 5g are formed on the side edges of the hanging portion 5a and the upper bent portion 5b of the bracket 5, respectively. Both flanges 5f and 5g are spot-welded at a position A in FIG. The bending rigidity of the hanging portion 5a is increased so that the hanging portion 5a can be prevented from buckling due to vertical compressive stress acting on the hanging portion 5a when the seat belt 2 is locked.
