Description

[0001]
[Industrial applications]
TECHNICAL FIELD The present invention relates to a vehicle body structure to which a seat belt disposed on a rear seat portion of a vehicle is rationally mounted.
[0002]
[Prior art]
FIG. 3 and FIG. 4 show a mounting structure of a seat belt disposed on a rear seat portion of a vehicle such as a passenger car or an RV (recreational vehicle).
The rear wheel house inner panel 101 that accommodates the tire 106 has a cabin side surface portion 102 formed as a substantially vertical surface. The lower end portion 104 of the cabin side surface portion 102 and the end portion 105 of the floor panel 103 are connected below the floor panel 103 by means such as spot welding.
[0003]
A seat cushion 107 is disposed above the floor panel 103, and a seat belt 108 is provided. A lower end portion of the seat belt 108 is connected to a belt anchor 109, and the belt anchor 109 is fixed to the vehicle interior side surface portion 102 of the rear wheel house inner panel 101 by a bolt 110 and a nut 111.
The seat belt mounting structure described above is also disclosed in, for example, Japanese Utility Model Publication No. Hei 7-2337.
[0004]
[Problems to be solved by the invention]
In some cases, a vehicle having the above-described structure is remodeled to extend the rear tread. The extension of the rear tread is useful for improving the running stability of the vehicle and improving the livability of the passenger compartment. When the model change is performed, as shown in FIG. 5, when the tire 106 and the rear wheel house inner panel 101 are moved in the direction of the arrow, a gap C ₁ corresponding to the extension of the rear tread between the tire 106 and the floor panel 103 is obtained. Is formed. To fill this gap C ₁ is necessary to manufacture one of the floor panel 103 or rear wheel house inner panel 101 the newly generated.
At this time, changing the rear wheel house inner panel 101 having a small press die is more economically advantageous than changing the large floor panel 103 having a press die.
[0005]
6, FIG. 7 shows a structure by bending the inclined surface 102a of the car side of the rear wheel house inner panel 101 inwardly by the upright angle theta ₁ with respect to the floor panel to fill the gap C _1. As shown in FIG. 6, is set to a position higher bending point K ₁ which folding is initiated based on the floor panel 103, the effect of enlarging the passenger compartment would be reduced.
Therefore, as shown in FIG. 7, it is preferable to set the inflection point K ₂ to a lower position, the rear wheel house inner panel 101 in order to press working, limits occurs in the position of the bending point K _2, considering the consumption of rigidity and steel panels, upright angle theta ₂ is preferably within the scope of the about vertical 5 degrees about 45 degrees.
[0006]
However, for example, in the case of 40mm extending the tread, the gap _{C 1} Half of 20mm, and the between the inclined surface 102b of the angle theta ₂ to 45 degrees length _{L 1} is not only slightly 28mm. Here, as in FIGS. 3 and 4, that is, even if the seat belt anchor 109 is to be attached to a place located at the lowermost part of the rear wheel inner panel 101 and close to the floor panel 103, the length L ₁ Is not possible.
The present invention provides a vehicle body structure that solves the above-mentioned problems.
[0007]
[Means for Solving the Problems]
In the vehicle body structure of the present invention, the rear wheel house inner panel joined to the floor panel has a first inclined surface joined at a small upright angle to the floor panel, and a large upright angle to the floor panel. And a second inclined surface that is joined with the second inclined surface, and the second inclined surface forms a mounting portion to which an anchor of the seat belt is fixed.
[0008]
[Action]
The cabin space is enlarged by reducing the rising angle of the first inclined surface, and the mounting space for the seat belt anchor is secured by increasing the rising angle of the second inclined surface.
[0009]
【Example】
FIG. 1 is a perspective view showing a vehicle body structure of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG.
In the vehicle body structure of the present invention, the end of the rear wheel house inner panel 10 on the floor panel 20 side is formed with the first inclined surface 12 and the second inclined surface 14. The edge 16 on the floor panel side of the first inclined surface 12 and the second inclined surface 14 forms the same side surface, and is spot welded together with the side surface 22 formed by bending the end of the floor panel 20. It is fixed by the above-mentioned means.
[0010]
The first inclined surface 12 extends in the axial direction of the vehicle body with respect to the floor panel 20, and is formed so that the width of the rear passenger compartment can be maximized. Specifically, by lowering the inflection point K ₃ of the first inclined surface 12 of the rear wheel house inner panel 10 on the floor panel side, forms upright angle theta ₃ of the floor panel 20 and the first inclined surface 12 It was configured to be 45 degrees.
[0011]
The second inclined surface 14 is configured such that the bending point K ₄ of the rear wheel house inner panel 10 is set at a position higher than the floor panel 20, and the upright angle θ ₄ with the floor panel 20 is 60 degrees. did. The length L ₂ of the second inclined surface 14 by this structure increases can be set. The lower end of the rear seat belt 50 is connected to an anchor 52, and the anchor 52 is fixed to the second inclined surface 14 via a bolt 60 and a spacer 62 with a nut (not shown). The second inclined surface 14 has a sufficient length for the attachment structure of the seat belt anchor 52.
The angle θ ₃ may be selected within a range of about 5 degrees up and down around 45 degrees with respect to the press working surface of the rear wheel house inner panel 10, and the angle θ ₄ is set to be an enlarged tread. From the relationship between the size of the seat belt anchor 52 and the width of the required mounting surface of the seat belt anchor 52, the height may be selected within a range of about 5 degrees up and down around 60 degrees.
[0012]
【The invention's effect】
As described above, according to the present invention, when a vehicle body having a large tread size is formed by sharing a floor panel, the first wheel is provided at the joint of the rear wheel house inner panel located on the side of the rear seat of the vehicle body with the floor panel. An inclined surface and a second inclined surface are formed.
[0013]
The first inclined surface is set at an angle of approximately 45 degrees with respect to the floor panel to improve the rigidity of the rear wheel house inner panel and maximize the space in the width direction of the passenger compartment by expanding the tread. Can be expanded to
[0014]
Although the second inclined surface has a short dimension in the axle direction, the second inclined surface stands upright at an angle of about 60 degrees with respect to the floor panel, and can secure a sufficient length for attaching the anchor of the seat belt. This change in the shape of the rear wheel house inner panel can be achieved by minimally changing the shape of the press die.
