It is characterized by having.

Further, in the backrest mounting structure for a vehicle according to the second aspect, the backrest support members 32 and 33 include a first backrest support member 32 fixed to an upper portion of the armrest portion, and a lower portion supporting the seat at a rear portion of the seat. A second backrest support member 33 fixed to the member and having an upper portion fixed to the first backrest support member;
d, a connecting portion A between the armrest member 31 and a connecting portion B between the armrest member 31 and the first backrest support member 32;
Backrest support member 32 and second backrest support member 33
And a straight line connecting the connecting portion C of the second backrest support member 33 and the connecting portion D of the seat support member 22f forms a substantially triangular shape when viewed from the vehicle width direction. Note that the numbers added to the above configuration are compared with the drawings for easy understanding of the present invention, and the configuration of the present invention is not limited by this.

Example An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall side view of a vehicle according to the present invention, in which a vehicle body frame 1 supports a front wheel 2 and a rear wheel 3 and has a floor plate 4 mounted thereon. And a rear seat 6 are provided. The front seat 5 and the rear seat 6 are provided with seats 7, 8 and backrests 9, 10, respectively. As a result, two passengers can sit on the front seat 5 and the rear seat 6 in the same direction. In addition, 11 is a forward / reverse switching lever, 12 is a handle, 13 is a front cover,
14 is a roof, 15 is a rear frame, and 16 is a luggage stand.

FIG. 2 is a side view of the front seat 5 in FIG. 1, FIG. 3 is a view as viewed from a direction III in FIG. 2, and FIG. 4 is an enlarged sectional view of a portion IV in FIG.

2 and 3, the body frame 1 is composed of three frame pipes 1a, 1b, 1c arranged in the front-rear direction, and the mounting members 21 are attached to the frame pipes 1a, 1b, 1c.
The floor plate 4 is fixed by a, 21b and 21c. Further, a first sheet support pipe 22a is vertically fixed to the left and right frame pipes 1a, 1c, and a second sheet support pipe 22b is disposed outside the first sheet support pipe 22a. It is stuck to. Further, a third seat support pipe 22c is vertically fixed to the center frame pipe 1b.

On the upper surfaces of the first and second sheet support pipes 22a and 22b, a fourth sheet support pipe 22d extending to both sides from the front of the sheet 7 and formed in a U-shape is fixed by welding. A fifth seat support pipe 22e is fixed to the rear of the fourth seat support pipe 22d, and the fifth support pipe 22e is fixed to the fifth support pipe 22e.
Is fixed to the third sheet support pipe 22c. Further, at the center of the fifth sheet support pipe 22e,
The sheet support pipe 22f is fixed.

Three mounting brackets 23 for supporting the backrest 9 are mounted on both sides of the fourth seat support pipe 22d and on the sixth seat support pipe 22f. This is the fourth
Referring to the drawing, a nut member 25 is provided in advance on the seat support pipe 22d (22f), and the mounting bracket 23 and the cover 26 are fastened and fixed to the nut member 25 by bolts 27. A mounting bracket 29 for mounting the seat 7 is provided at the front of the fourth seat support pipe 22d.
Is fixed, and by fitting a hook 30 provided on the sheet 7 side into a hole formed in the mounting bracket 29,
The seat 7 is rotatable and detachable with the fitting portion as a fulcrum.

The first to sixth sheet support pipes 22a to 22f constitute a sheet support member of the present invention. A substantially U-shaped armrest member 31 composed of an armrest portion 31a and a grip portion 31b is fixed to mounting brackets 23 provided on both sides of the fourth seat support pipe 22d.
The armrest portion 31a extends obliquely upward from the side of the seat 7 through an intermediate portion of the front and rear width of the seat 7, and is provided with a grip portion 31a.
b is bent and extended inward in the vehicle width direction above the armrest portion 31a. A first backrest support member 32 is erected and fixed on the upper left and right sides of the armrest member 31 in the vehicle width direction, and a mounting bracket 23 attached to a central portion of the first backrest support member 32 and the sixth seat support pipe 22f. Between them, the second backrest support member 33 is fixed. The two backrests 9 are attached to the first backrest support member 32 such that the upper end of the armrest member 31 is located below the grip portion 31b.

As is apparent from FIG. 2, in the present invention, the connection portion A between the seat support member 22d and the armrest member 31, the connection portion B between the armrest member 31 and the first backrest support member 32, the first backrest A straight line connecting the connecting portion C between the supporting member 32 and the second backrest supporting member 33 and the connecting portion D between the second backrest supporting member 33 and the seat supporting member 22f form a substantially triangle when viewed from the vehicle width direction. Since the backrest 9 is supported, the backrest 9 can be firmly attached.

[Effect of the Invention] According to the backrest mounting structure according to claim 1 of the present invention, the armrest of the occupant sitting on the front seat has a simple structure in which one long member is appropriately bent and configured. Also, it can function as a grip for an occupant sitting in the rear seat. Further, according to the backrest mounting structure of the second aspect, the armrest member and the backrest support member form a truss structure, so that the backrest can be firmly mounted.
