Description

[Detailed Description of the Invention] According to the present invention, motorcycle seats and car cushions are generally made of practical materials whose cushioning properties, that is, hardness ζ, are influenced by the material used for the air pack. When used, the cushioning characteristics are hard, and when an impact load is applied, a feeling of bottoming out is noticeable and comfortable cushioning cannot be obtained. It is being In addition, since the conventional air cushion body has a general ζ-gonal frontal cross-sectional shape, it responds to the tilting load in the diagonal direction in a complicated manner, giving the occupant a feeling of a foreign body and ensuring stable cushioning performance.
can't get it.

Since the conventional air cushion body employs a sealed air pack, it is not possible to adjust the height of the entire seat or the firmness of the cushion.

Two examples of improved application of the present invention to eliminate such drawbacks will be described with reference to the drawings.

Figure 1 is a vertical cross-sectional view of the combined sheet, and is the seating part Y#1g f
4. An air cushion body 3Y according to the present invention is located between the cushion #1 made of a 4-y ohm fist, etc., and the seat 7 frame 2.
The intervening surface is encapsulated by Hyx epidermis 4.

It has 3 air cushion bodies, a main air pack 3a and a sub air pack 3b with a smaller capacity, both air packs 3a and 3bljt are connected to each other by L through the communication body 3c, and the metal rod is connected to one bag body. This is how it is formed. A trap air valve 5 is attached to a part of the auxiliary air pack 3b to control the amount of air vaI4 in the air pack. Also.

The main air pack is placed in the area that supports the passenger's load like a living tree, and the secondary air pack is placed in the area where the passenger's load is not so much applied.

Furthermore, the front vertical cross-sectional shape of the main air bag 3a of the air cushion body according to the present invention can be formed into a rectangular shape as shown in FIG. Make a book.

The above configuration is for a single-person motorcycle seat.
However, in the case of a double seat for two people, the combination of the main air bag 3a and the secondary air bag 3b and the cushion body 3 are combined in a double manner as shown in the fifth figure. If you can make A Ren Koji ζ mutually, it will be L. 't-ta.

Instead of the laminated structure of the near pack and the cushion material, it is also possible to integrally mold the air pack Y and the L part embedded in the cushion material.

The present invention is as described above lζ main air pack 3a,! :iQ
Since the air pack is connected to the air pack 3b and the communication rod 3c, when an impact load is applied, the load becomes heavy (the applied air pack is connected to other air packs via the communication path 31'). There is an outflow movement of air, which accumulates in the air pack! Regardless of the material used, the feeling of bottoming out upon impact is alleviated and good cushioning performance is obtained.

ire, in the present invention, near pack (7) -s
Since an air valve 5 is attached to the seat, the amount of air in the air pack can be adjusted arbitrarily, and the firmness of the cushion as well as the height of the seat can be adjusted.

Furthermore, if the main airbag 3a is formed in a substantially semi-circular cross-sectional shape, it should respond at an acute angle to an impact load from an oblique direction to give a foreign body sensation such as hardness or pain. <Comfortable cushioning? Provided.

The air cushion body that the present invention maintains is based on the above L points! Excellent cushioning properties when using It is extremely effective when used as a seat for motocross motorcycles, which have a heavy impact load (and may be subject to impacts from the top, bottom, left, and right).For motocross motorcycle seats. Not only for seats that are exposed to rainwater, such as boat seats and outdoor furniture seats, use a cushioning material such as foam ode in a large amount (1M!), as water will seep into the cushioning material and the cushioning property I! Although it has the disadvantage of causing deterioration, when using the air cushion according to the present invention, it is possible to obtain a sufficiently good cushioning performance by itself, so the cushioning material layer is thin enough to maintain the feeling of sitting. Because of this, the above-mentioned inconvenience does not occur.
