[0001]
BACKGROUND OF THE INVENTION
The present invention particularly relates to a structure for attaching a seat belt retractor to a rear seat occupant in an open car having a rear seat.
[0002]
[Prior art]
In a conventional open car having a rear seat, as illustrated in FIGS. 4 and 5, a rear seat back plate 1 extending in the vehicle width direction is provided at a rear portion on the rear floor 2, and both left and right ends of the rear seat back plate 1 are provided. Towers 4 extending upward from the side members 3 are respectively installed, and a folded hood support arm (not shown) is accommodated in a space between the tower 4 and the inner wall 5 of the vehicle body, while the tower 4 has a vehicle rear side. The mounting belt 6 is fixed to the wall surface, and the seat belt 8 extending from the retractor 7 attached to the mounting bolt 6 extends upward along the vehicle rear side wall surface of the tower 4, and then the front of the vehicle at the top of the tower 4. It was guided to reach the rear seat occupant (not shown).
[0003]
However, in this case, in order to attach the retractor 7 to the mounting bolt 6 fixed to the vehicle rear side wall surface of the tower 4, an operator must cross the rear seat back plate 1 from the vehicle front toward the vehicle rear. Therefore, there is a problem that workability becomes very poor.
[0004]
Further, if the retractor 7 is attached to the vehicle front side of the tower 4 so as to facilitate the attachment work of the retractor 7, it is necessary to move the tower 4 to the rear of the vehicle in order to ensure the comfortability of the rear seat. Therefore, there arises a problem that it is difficult to make a space for storing the hood on the vehicle rear side of the tower 4.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to enable a seat belt retractor for a rear seat occupant to be installed in an open car having a rear seat easily to a tower behind the rear seat without interfering with hood storage. It is to do.
[0006]
[Means for Solving the Problems]
Therefore, a vehicle body structure according to the present invention includes a substantially U-shaped tower body having a lower portion attached to a side member and extending upwardly and having a horizontal section opened forward of the vehicle in an open car having a rear seat, and the tower body. And a lid member that is fixed from the front side of the vehicle and covers the opening of the tower body, a tower with a closed cross section is formed behind the rear seat, and a seat belt retractor for the rear seat occupant is installed in the tower. The seat belt extended upward from the retractor is configured to be bent and guided forward of the vehicle near the top of the tower.
[0007]
That is, since the tower main body with the lower part attached to the side member and extending upward has a substantially U-shaped horizontal cross section that opens to the front of the vehicle, the retractor can be easily installed from the front of the vehicle into the tower through the opening of the tower main body. By fixing the lid member from the front side of the vehicle to the opening of the tower body after installing the retractor, the retractor can be easily placed in the tower, and the tower is formed in a closed cross section with the tower body and the lid member. Therefore, it is possible to easily increase the rigidity of the tower and to reduce the horizontal section of the tower, and therefore, it is possible to relatively reduce the living space in the rear seat while securing the folding storage space of the hood that covers the top of the vehicle. Can be easily enlarged.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
In FIG. 1 to FIG. 3, a tower 10 disposed on the left and right in the rear of the rear seat of an open car having a rear seat has a tower body 11 having a substantially U-shaped horizontal section opened to the front of the vehicle, and a horizontal section. A lid member 12 that is substantially U-shaped and is opened to the rear of the vehicle. The tower body 11 is formed of a double plate by an outer plate 13 and an internal phosphorus hose 14 that are spot-welded to each other. The outer plate 15 and the inner phosphorus hose 16 that are spot-welded to each other are formed in a double manner.
[0009]
The left and right tower bodies 11 are respectively fitted with side walls 18 on left and right side members 17 having a substantially U-shaped cross section opened upward and spot welded to the side members 17, while a lower flange 19 is formed on the lower surface of the rear floor 20. Spot welded.
[0010]
The lower part of the lid member 12 is appropriately bolted to the front floor 21, and the left and right side walls 22 are appropriately bolted to the left and right side walls 23 of the tower body 11 to cover the opening 24 of the tower body 11 from the front of the vehicle. The tower 10 is generally formed in a closed cross-sectional structure.
[0011]
On the other hand, the retractor bracket 30 having a substantially U-shaped horizontal cross section opened to the front of the vehicle is fitted into the side member 17 so that the left and right flange portions 31 sandwich the tower body side wall 18 or directly to the side member 17. It is spot welded, and a nut 33 is welded to the vehicle rear side of the upper end ear 32.
[0012]
Further, the bracket 35 is fixed to the lower end of the retractor 34, and the bolt 36 is inserted into the bracket 35 and the retractor bracket ear 32 and screwed into the nut 33, whereby the retractor 34 is disposed in the tower 10, and the retractor 34. The seat belt 37 extending upward in the tower 10 is guided by the ring 38 fixed near the top of the tower 10 so as to be bent forward of the vehicle, and is inserted through the opening 41 formed in the trim 40 covering the tower 10. And it extends to the shoulder of the rear seat occupant (not shown).
[0013]
In the above apparatus, the tower body 11 is formed in a closed cross section by the outer plate 13 and the internal phosphorus hose 14 and has high rigidity, and the lid member 12 is also formed in a closed cross section by the outer plate 15 and the internal phosphorus hose 16 and has high rigidity. In particular, since the cross-sectional area of the tower main body 11 is relatively large, its rigidity is remarkably enhanced. As a result, the tower 10 formed in a closed cross-sectional structure by the tower main body 11 and the lid member 12 has rigidity. Since the cross-sectional area of the entire tower 10 can be made relatively small, the foldable storage space of the hood covering the upper side of the vehicle can be provided as the tower 10 even if the open car has a rear seat. By installing the tower 10 relatively on the vehicle rear side while securing the vehicle rear side, the living space in the rear seat can be increased. The living property can be easily improved.
[0014]
Further, since the tower body 11 and the retractor bracket 30 are fixed to the side member 17 by spot welding, their assembly is easy. On the other hand, the bracket 35 of the retractor 34 is attached to the retractor bracket ear 32 by a bolt 36 from the front side of the vehicle. , The retractor 34 can be installed in the tower body 11 from the vehicle front side through the tower body opening 24, and the lid member 12 is appropriately bolted to the front floor 21 and the tower body to Since it can be easily assembled from the side, not only is troublesome work such as gas welding unnecessary when the tower 10 is assembled, but also the assembly work of the lid member 12 and the retractor 34 can be advanced from the front side of the vehicle. Assembling work of tower 10 and retractor 34 Is simplified, it is possible to easily reduce the required number of steps.
[0015]
【The invention's effect】
In the vehicle body structure according to the present invention, the tower behind the rear seat is formed in a closed cross section by a tower body having a substantially U-shaped horizontal section and a lid member that covers the opening of the tower body from the front side of the vehicle. The seat belt retractor for the seat occupant can be installed in the tower from the front side of the vehicle through the opening of the tower body, so the installation work of the tower and retractor is relatively easy, and the tower is closed by the tower body and the lid member. Because it is formed, it is possible to make the tower horizontal section small by easily increasing the rigidity of the tower, so it is a sports car with a rear seat while securing the folding storage space of the top covering the vehicle Even if it exists, there exists the feature which can make the living space in a backseat comparatively large and can improve the comfortability of a backseat easily.
