Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a seat structure for a so-called straddle-type heavy vehicle that is operated while straddling the seat, and particularly to a four-wheeled motor vehicle for driving on rough terrain that has low-pressure tires on its wheels. The present invention relates to a seat structure suitable for such applications.

[Prior art]

A saddle (1) with wheels equipped with low-pressure tires (so-called balloon tires) with an air pressure of about 0.1 to 0.3 kg/cn is suitable for driving on rough terrain. When riding such a straddle-type vehicle on rough terrain, the rider shifts his/her weight back and forth as appropriate to maintain balance while driving. In order to prevent the rider's groin from being damaged by the fuel tank during such weight shifting, there are some models in which the front end of the seat rides up to the top of the rear of the fuel tank, covering both sides of it.

However, as mentioned above, when the front end of the seat rests on the upper rear surface of the fuel tank, a step is formed between the side of the front end of the seat and the side of the fuel tank, and the rider's inner thigh comes into contact with this step, causing a feeling of discomfort. There is a problem that it gives a bad feeling to the vehicle.

[Purpose of the invention]

An object of the present invention is to provide saddle riding in which the front end of the seat covers the rear upper surface of the fuel tank. To provide a seat structure that does not give a feeling of discomfort when riding in a vehicle.

[Structure of the invention]

(2)! To achieve the above object, the seat structure of the present invention provides a straddle type vehicle in which a fuel tank is disposed in the front part of the seat, and the rear and upper surface of the fuel tank is covered by the front end of the seat. The fuel tank is characterized in that the right and left sides of the fuel tank are extended in front of both sides of the fuel tank, and the extensions are locked to the sides of the fuel tank.

[Embodiments of the invention]

The present invention will be explained below with reference to embodiments shown in the drawings.

The vehicle shown in Figure 1.2 is a four-wheeled motor vehicle for traveling on rough terrain, and the front wheels 1.1 and rear wheels 2 and 2 are installed at the front and rear of the vehicle body.
The air pressure is 0.1~0゜3kI+/c11! Low pressure tires are installed.

The - part of the 111 wheel 1.1 is covered by a front fender 3.3 that is integrated with the cowling that covers the front of the vehicle, and the rear wheel 2.
．． At the top of 2, left and right fenders 4, 4 are integrally molded.
is covered. Reference numeral 5 denotes an engine, above which a fuel tank 6 made of synthetic resin and a seat 7 are arranged in the front and rear.

(3) The above Seat I/7 has a bottom plate 8 integrally molded with resin at the bottom.
on which a cushioning material 9 such as foamed polyurethane is applied.
It is constructed by placing a piece of paper on top and covering its two sides with 1° of skin. The front end of the seat 7 having such a structure is
'+It end center part 7a rises diagonally upward and burns*.
(It rides on the rear upper surface of the fuel tank 6 and covers the upper surface.Furthermore, extension parts 7b, 7b extend from both left and right sides of the front end center part 7a, and cover the entire both sides of the fuel tank 6 as described in the following. There is.

The left and right extensions 711 and 713 of the sheet 1-7 are inserted into the tPA cell 1 tank in the four parts 11 provided on the inner surface of the bottom plate E (as shown in Figure 3.4.5). When the hook 2 is opened and inserted from the side of the hook 12, it is locked. When the hook 12 is inserted in this way, it cannot be moved in the left-right direction by the wall 11b. The hook I2 is connected to the fuel tank 6.
It is molded using the base of a two-part mold.

(4) Further, as shown in FIG. 6, the rising portion of the front center portion 7a of the seat 7 is brought into contact with the upper surface of the fuel tank 6 via a rubber seat 13 attached to the bottom plate 8 thereof. In addition, as shown in FIG. 7, the middle part of the seat 7 has a U-shaped bracket 1 with an integrally molded hook 14 projecting downward from the bottom plate 8 fixed to the vehicle body frame 15 located at the center of the vehicle body. It is locked by hooking it to -16. On both sides of the placket 16 are seat rails 18.1.
The front end of the seat 8 is fixed and extends rearward, and the rear end of the seat 7 is locked to the rear 61i1 of the seat rail 18 via a stopper 17.

- In the above-mentioned four-wheeled motor vehicle, since the extensions 7b and 7b extending from the front ends of the seals 1 to 7 to both sides cover both sides of the fuel tank 6, the front ends of the seals 1 and 7 and the fuel tank 6 No step is formed between them. Therefore, as shown in Figure 1.2, when rider R sits on seat 7, even if he shifts his weight back and forth, his inner thighs (
5) Since it always comes into contact with the surface of the extension part 71) and never comes into contact with a step or the like, there is no need to feel uncomfortable. In addition, since the extension parts 7b and 7b are configured to be locked to the side surface of the fuel tank 6, they do not float even when the rider shifts his/her weight back and forth. can be carried out smoothly.

In addition, although the above-mentioned embodiment was explained in the case of a four-wheeled motor vehicle equipped with low-pressure tires, the present invention is also applicable to other transferable vehicles such as motorcycles and three-wheeled motorbikes. It can be applied not only to Tie-1, but also to those equipped with general Tie-1.

〔Effect of the invention〕

As described above, the present invention provides a straddle type vehicle in which a fuel tank is disposed in the front part of the seat, and the rear surface of the fuel tank is covered by the front end of the seat. extends toward the front of both sides of the fuel tank, and the extensions are locked to the sides of the fuel tank (6), so that when the rider sits on the seat, the rider's inner thighs are always aligned with the surface of the extensions. I will come into contact with it, and I will not feel uncomfortable. Moreover, since the seat extension part is locked to the side surface of the fuel tank, even if the rider shifts his or her weight back and forth, the seat does not lift up, and the rider's weight can be shifted smoothly.
