Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a storage structure for a third seat in a body vehicle with a chassis frame, and more particularly, to a third seat storage structure in a body vehicle with a frame that has a high rigidity around the storage portion so that the third seat can be stably stored.
[0002]
[Prior art]
Body cars having a third seat include a frameless monocoque structure and a structure with a chassis frame. In the case of the former monocoque body vehicle, the frameless structure as described above is formed with high rigidity as a whole, and the storage space around which the third seat is stored is also formed with relatively high rigidity. Therefore, for example, as shown in Japanese Utility Model Laid-Open No. 5-40029, it is possible to form a storage recess for storing the sheet on the rear end side of the floor and fold and store the third sheet.
[0003]
[Problems to be solved by the invention]
However, in the case of a body vehicle with a frame, the floor structure of the body mounted on the frame is formed with relatively low rigidity, so a recess is formed on the rear end side of the body, and a third seat is folded and stored in the recess There are problems that are difficult to do. For this reason, in the case of a body vehicle with a frame, a flip-up method is generally employed in which a third seat is folded and stood on the side wall side of the body. Therefore, there is a problem that the floor area is narrowed and a problem that the rear view is deteriorated. Furthermore, in the case of this type, there is also a problem that requires a device for attaching the belt anchor.
[0004]
Japanese Utility Model Laid-Open No. 5-37661 is known as one of known techniques for reinforcing a seat mounting portion in a body car with a frame. The “lower vehicle body structure of an automobile” has a longitudinal direction between a first cross member disposed in the vehicle width direction and a second cross member disposed behind the first cross member in the vehicle width direction. The floor reinforcement member is provided, and an anchor reinforcement for fixing the seat belt anchor to the connecting portion of the floor reinforcement member is provided. With the above structure, the floor panel at the part to which the seat is attached is reinforced. However, this known technique is not a reinforcing structure around the storage space in which the third sheet is stored, and is different from the present invention.
[0005]
The present invention was devised in view of the above circumstances, and provided a highly rigid storage space for safely storing a third seat in a body car with a frame, and adopted a light-weight structural component with a small number of parts. The purpose is to provide a third seat storage structure in a body vehicle with a frame that reduces the weight and effectively uses the floor area and expands the field of view.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has a rear end cross member that is disposed so as to surround the space portion, and that is secured to the rear end cross member.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a third seat storage structure in a body vehicle with a frame of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a schematic structure of the rear part of a body vehicle with a frame. A concave space 4 in which the third seat 5 is accommodated is formed at the center of the rear floor panel 13. For convenience of explanation, the rear floor panel 13 on the front side of the space portion 4 among the rear floor panels 13 surrounding the space portion 4 is referred to as a front rear floor panel 13a, and the rear floor panel 13 on the side of the space portion 4 is referred to as a side rear floor. This is referred to as a panel 13b. A rear end cross member 14 having a relatively high rigidity is disposed behind the space portion 4. That is, the space 4 is surrounded by the front rear floor panel 13a, the side rear floor panels 13b and 13b, and the rear end cross member 14. A wheel house 15 is provided at a portion where the front rear floor panel 13a and the side rear floor panel 13b intersect. In the case of this example, the third seat 5 is divided into two parts, and each of the third seats 5 is disposed on the front rear floor panel 13a at a position relatively close to the wheel house 15.
[0009]
Next, the reinforcing structure of the present invention around the space 4 will be described with reference to FIGS. A luggage side drain force 1 is disposed in the vicinity of the space portion 4 of the side rear floor panel 13b along the front-rear direction. The luggage side drain force 1 is formed of a member having a U-shaped cross section that forms a flange 1a on the upper surface, and the front side is fixed to the wheel house 15 side and the rear side is fixed to the rear end cross member 14 side. The flange 1a is fixed to the lower surface of the side rear floor panel 13b.
[0010]
A luggage floor cross member 2 is disposed in the vicinity of the space 4 of the front rear floor panel 13a along the left-right direction. The luggage floor cross member 2 has a U-shaped cross section that forms a flange 2a on the upper surface. Both end sides are fixed to the wheel house 15 side, and the flange 2a is fixed to the lower surface of the front rear floor panel 13a.
[0011]
The wheel house inner patch 3 is fixed inside the wheel house 15 along the curve of the wheel house 15. The wheel house inner patch 3 is disposed at least at a portion to which the luggage side drain force 1 and the luggage floor cross member 2 are fixed.
[0012]
The space 4 is reinforced by the luggage side drain force 1, the luggage floor cross member 2 and the wheel house inner patch 3 described above. On the other hand, the third seat 5 includes a seat 5a and a seat back 5b, and a seat structure member 6 is formed as a basic reinforcing member of the seat 5a on the lower surface side of the seat 5a. A seat hinge pin 7 is fixed to the seat structure member 6. The seat hinge pin 7 is disposed so as to protrude.
[0013]
As shown in FIG. 1 and the like, a reinforcing member 8 is fixed to the side of the wheel house 15 of the luggage side drain force 1. 2, the lower end of the seat hinge 9 is connected and fixed to the reinforcing member 8 with a bolt or the like. The seat hinge 9 is formed of a bent plate member, and the seat hinge pin 7 is inserted into the intermediate gap portion 10. Further, the upper end side of the seat hinge 9 is connected and fixed to the wheel house inner patch 3 of the wheel house 15 by bolts or the like. The seat hinge 9 pivotally supports the seat hinge pin 7.
[0014]
On the other hand, the reinforcing member 11 is fixed to the luggage floor cross member 2 on the wheel house 15 side. As shown in FIG. 4, a foot member 12 fixed to the sheet structure member 6 of the third sheet 5 is connected and fixed to the reinforcing member 11 with a bolt or the like.

When the third seat 5 is mounted, the lower surface of the seat seat 5a is mounted on the front rear floor panel 13a, and the seat structural member 6 is fixed to the luggage floor cross member 2 via the reinforcing member 11 as described above. The hinge pin 7 is pivotally supported by the seat hinge 9 and supported on the side rear floor panel 13b. The third seat 5 itself is made of a rigid body that forms the sheet structural member 6 as a basic reinforcing member, and as described above, each portion on which the third seat 5 is mounted is a highly rigid luggage side disposed in the front-rear and left-right directions. Since it is reinforced by the reinforcement 1 or the luggage floor cross member 2 or the like, it becomes a cross-girder structure as a whole and has high rigidity. Accordingly, the third seat 5 is stably held on the rear floor panel 13.
[0016]
Next, a method for storing the third sheet 5 in the space 4 when not in use will be described. First, the connection between the foot member 12 of the third seat 5 and the reinforcing member 11 is released. Next, as shown by an arrow C in FIG. 6, the seat back 5b is folded and stacked on the seat seat 5a. Subsequently, when the front surface of the seat 5a is gripped and the entire third seat 5 is rotated in the direction of arrow D in FIG. 6, the third seat 5 is completely stored in the space 4 as shown in FIG. Thus, the third seat 5 is eliminated on the surface of the rear floor panel 13, and the entire area of the rear floor panel 13 is effectively used.
[0017]
