Moreover, the latter can be examined by not only being able to change the thickness of the sheet as a whole, but also changing it partially.

[Il1 Problem to be Solved by the Invention] However, the former has a problem in that the thickness of each part of the sheet cannot be partially adjusted.

In addition, since the latter has multiple airbags installed independently, it is possible to partially adjust the thickness of each part of the seat, but each airbag can be connected to, for example, an air pump installed in the car body to supply air. Air needs to be replenished, the work of supplying air is troublesome, and the structure is complicated.

This invention was made in view of the above circumstances, and an object thereof is to provide a seat device for a motorcycle that has a simple structure, can easily supply air, and can easily readjust the seat. It is said that

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a seat device for a motorcycle in which a seat having an air bag is provided in a frame, and a plurality of independent air bags are provided inside the seat. , these airbags are connected through ventilation pipes, each of the ventilation pipes is provided with an air adjustment valve, one of the airbags is provided with an air injection pipe that communicates with the outside air, and this air injection pipe It features an air injection valve.

[Function] In this invention, when air is supplied by opening the air injection valve provided in the air injection pipe, air can be simultaneously injected into a plurality of airbags connected by the ventilation pipes, and air can be injected into the airbags at the same time. Supply work is easy.

In addition, air can be exchanged between multiple airbags by adjusting the air adjustment valve installed in the ventilation pipe that connects the airbags. This allows you to easily adjust the seat posture by simply injecting air. Can be readjusted.

[Embodiments] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a sectional view of a sheet device that is an embodiment of the present invention, Fig. 2 is a plan view thereof, Fig. 3 is a sectional view of the sheet with the thickness of each part partially changed, and Fig. 4. 2 is a cross-sectional view of a state in which the thickness of the entire sheet is changed.

Reference numeral 1 in the figure is a seat of a motorcycle, and a cushioning material 3 provided on the bottom plate 2 of the seat 1 is covered with a seat cover 4, and airbags 5a to 5e are placed inside the cushioning material 3.
There are several.

The bottom plate 2 of the seat 1 is made of a highly rigid resin, and its front side 2a is curved upward, so that it can be inserted into the seat frame behind a fuel tank (not shown). The seat cover 4 fixed to the bottom plate 2 is made of a flexible material such as resin, and can allow the cushion material 3 to deform.

Airbag 58 provided inside this cushion material 3
5e are long in the seat width direction and are arranged side by side in the front-rear direction of the seat 1. The airbags 58 to 5e are independent, and each airbag 5a to 5e
are connected in series through ventilation pipes 6a to 6d, and this ventilation pipe 68
-6d are provided with air adjustment valves 78-7d, respectively. The air adjustment valves 7a to 7d are composed of electromagnetic valves, and the air adjustment valves 78 to 7d are opened and closed by a valve operation switch 9 controlled by a microcomputer 8.

The rearmost airbag 5e is provided with an air injection pipe 10 that communicates with the outside air, and this air injection pipe 10 is connected to an air injection valve 11 provided on the bottom plate 2 of the seat 1.

Therefore, each of the air adjustment valves 7a to 7d is opened, the air injection valve 1] is opened, and the air pump P connected to the air injection valve 11 is driven to inject air from the air injection pipe 1o. When air is supplied, air is simultaneously supplied to each of the airbags 5a to 5e, and the seat 1 becomes shaped as shown in FIG. In this state, the air injection valve 11 is closed, and each of the air adjustment valves 78 to 7d is closed.

For example, if you want to lower the front side of the seat and raise the rear side of the seat as shown in Figure 3, the air injection valve 1
1 with each air adjustment valve 7 closed.
When seats 8 to 7d are opened and the front side of the seat is pressed down to lower it, air is driven from the front airbag to the rear airbag.

As a result, the amount of air in the front airbags 5a, 5b decreases, and the amount of air in the rear airbags 5d, 5e increases, and in this state, the respective air adjustment valves are closed. Therefore, the airbag closer to the front takes on a flat shape, and the seat cover 4 also lowers accordingly, making the front seat thinner, and the airbag closer to the rear becomes more fitted, and the seat cover 4 also rises accordingly. The rear sheet is thicker. In this state, when each air adjustment valve 78 to 7d is closed, air is exchanged within each air bag 58 to 5d to adjust the amount of air and partially adjust the thickness of each part of the seat. can.

Next, as shown in Fig. 4, if you want to make the entire sheet thinner and lower, open the air injection valve 11, open each air adjustment valve 78 to 7d, and press the entire sheet from above. , a predetermined amount of air is discharged from the air injection pipe 11 to reduce the total amount of air. When the sheet has a predetermined shape, the air injection valve 11 and the air adjustment valves 78 to
When 7d is closed, the airbags 58 to 5e take on a flat shape, and the entire seat is lowered, allowing the seat to be lowered.

Also, by increasing or decreasing the total amount of air in this way,
Not only can the thickness of the sheet be adjusted, but also the hardness of the sheet can be adjusted as well. [Effects of the Invention] As described above, in this invention, a plurality of independent airbags are provided inside the seat. , these airbags are connected via ventilation pipes, each of the ventilation pipes is provided with an air adjustment valve, and one of the airbags is provided with an air injection pipe portion that communicates with the outside air, and furthermore, this air injection Since the pipe is equipped with an air adjustment valve, by opening the air injection valve installed in the air injection pipe and connecting an air pump to supply air, air can be injected into multiple airbags connected by the ventilation pipe at the same time. can.

Therefore, there is no need to equip the car body with an air pump, and when supplying air, it is simply connected to the air injection valve, making it easy to supply air to the airbag, and the thickness of each part of the seat can be partially adjusted. can.

In addition, air can be exchanged between multiple airbags by adjusting the air adjustment valve installed in the ventilation pipe that connects each airbag, making it easy to adjust the seat posture by simply supplying air. can be readjusted.
