Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riding type vehicle such as a motorcycle or a four-wheeled vehicle, and more particularly to a vehicle body structure around a seat thereof.

[0002]

2. Description of the Related Art A seat for a motorcycle has a structure in which a cushion material formed of urethane foam is stacked on a seat bottom plate and the cushion material is integrally covered with a seat skin.

The seats of this type are used differently depending on the type of vehicle, so that the shape and hardness of the seats are different. For example, in road sports vehicles whose main purpose is touring, comfortable sitting comfort is required to reduce fatigue during long-distance driving, whereas in road racers or trial cars, weight transfer rather than sitting comfort is required. It is required to be able to do quickly. Therefore, the seats of road racers and trial vehicles are hard and extremely thin, and this kind of seat is not suitable for long-distance running.

By the way, in recent years, motorcycles have been diversified in how they are used as leisure, and there is a tendency that there are various ways of enjoying and traveling. Specifically, there is an increasing demand to drive both paved roads such as public roads and rough terrain such as wilderness and rocks regardless of the road surface condition. Motorcycles designed to be able to drive both have attracted attention.

In the case of such a motorcycle, when trial-driving on rough terrain such as a rocky place, most of the driver lifts his / her waist from the seat and frequently shifts the weight forward, backward, left and right. It is preferable that it is thin and hard so as not to interfere. On the other hand, when moving to a place where you can run a trial, the driver sits on the seat and travels, similar to general touring, so the seat is soft and thick and comfortable to sit on. Will be desired.

[0006]

However, although some conventional motorcycles have seats of different forms as options, basically only one kind of seat is attached to the frame, It has not been possible to easily change the motorcycle itself to have different specifications depending on the application. Therefore, in order to change the standard equipped seat to the specification according to the type of travel, there is no unexpected method to carry another dedicated seat on a carrier etc. or to replace the seat in advance. This is one of the factors that hinder the response to ever-diversifying user needs.

The present invention has been made under such circumstances, and it is possible to freely use the two types of seat portions according to the application and the running form, and to make the specifications suitable for the purpose of use and the type of running. An object of the present invention is to provide a body structure of a riding type vehicle that can be easily tailored each time.

[0008]

In order to achieve the above object, the present invention has a frame in which a fuel tank connected to a fuel supply device of an engine and a continuous seat at the rear of the fuel tank are mounted side by side in front and back. It is premised on a riding type vehicle in which the driver sits on this seat in a straddled posture.

The seat is detachably supported on the frame by a first seat portion fixed to the frame, and the first seat portion covered with the first seat portion from above. And a second sheet portion having a different form from the portion.

[0010]

According to this structure, the first seat portion and the second seat portion are arranged on the frame in two steps, that is, when the second seat portion is attached and when the second seat portion is removed. The form of the sheet can be changed with and.

Therefore, if the second seat portion is selectively attached and detached each time according to the purpose of use of the vehicle and the type of traveling, the two kinds of seat portions can be freely used according to the use. The vehicle can be easily tailored to have different seat configurations.
