設けられている。(Prior art) Conventionally, automobile seats have been manufactured using, for example,
There is one constructed as shown in Japanese Patent No. 153960. According to this, a gap is formed inside the seat frame, and a cushion member is provided on the seat frame. Further, an airtight cover is provided to cover the upper surface side of the cushion member, and a first ventilation hole is provided to communicate the space closed by the seat frame and the cover with the void.
（考案が解決しようとする問題点）
ところで、上記従来構成によれば、シート内部
には空隙と空間の両者によつて十分の空気量が溜
められているため、仮に、上記通気孔の開口面積
が大きいとすると、着座者によりシートに衝撃的
な負荷が加えられたときには、上記空気の弾性変
形による縮小量が大きくなり、よつて、上記衝撃
は効果的に吸収されると考えられる。(Problem to be solved by the invention) By the way, according to the above-mentioned conventional structure, since a sufficient amount of air is stored inside the seat by both the voids and spaces, if the opening area of the above-mentioned ventilation hole is If is large, when an impact load is applied to the seat by a seated person, the amount of contraction due to the elastic deformation of the air will be large, and therefore the impact will be effectively absorbed.
しかし、上記したように着座者によりシートに
負荷を加えて空間内の空気が通気孔を通つて空隙
内に流入するとき、この通気孔を流れる空気の流
体抵抗は小さいため、空間内の空気に所望のばね
定数を得ることはできず、つまり、着座者の体重
や好みに応じた座り心地を得ることはできない。 However, as mentioned above, when a seated person applies a load to the seat and the air in the space flows into the gap through the vent, the fluid resistance of the air flowing through the vent is small, so the air in the space It is not possible to obtain a desired spring constant, that is, it is not possible to obtain a sitting comfort that corresponds to the weight and preferences of the seated person.
一方、上記とは異なり、仮に、通気孔の開口面
積が小さいと、この通気孔を流れる空気の流体抵
抗は大きくなるため、空間内の空気に所望のばね
定数を得ることができる。 On the other hand, unlike the above, if the opening area of the vent hole is small, the fluid resistance of the air flowing through the vent hole will be large, so that a desired spring constant can be obtained for the air in the space.
しかし、この場合には、上記着座者によるシー
トへの衝撃的な負荷は、主に空間内の空気の弾性
によつて支持されるだけで、この空気には空隙の
空気は含まれないため、上記衝撃が十分には吸収
されないおそれがある。 However, in this case, the impact load on the seat by the seated person is mainly supported only by the elasticity of the air in the space, and this air does not include the air in the void. There is a possibility that the above-mentioned impact will not be absorbed sufficiently.
（考案の目的）

する。(Purpose of the invention) This invention was made with attention to the above-mentioned circumstances, and is designed to effectively absorb the impact when an impact load is applied to the seat by a seated person. Furthermore, the purpose is to make it possible to adjust the spring constant of the air inside the seat over a wide range, thereby increasing the selection range of seat riding comfort.

（図示矢印Ｂ図示）。 When the seat 1 is subjected to vibrations caused by the running of the car or a load is applied to the seat 1 by a seated person (indicated by an arrow P in the figure), air flows from the space 8 through the gap 10 as the cushion pad 4 is elastically deformed. It flows out from the pores 13 (indicated by arrow A in the figure).
Further, when the cushion pad 4 is restored by its elastic deformation (as shown by arrow S in the figure), air flows into the space 8 from the second ventilation hole 13 through the gap 10 (as shown by arrow B in the figure).

貫通して弁体１６にねじ止めされている。 The flow rate regulating valve 15 will be explained with reference to FIGS. 1 and 4. This flow rate regulating valve 15 is the second
A valve body 16 is provided on the front surface of the vent hole 13 so as to be rotatable around an axis.
A plurality of communication holes 17 are formed at equal intervals in the circumferential direction of 6. These communication holes 17 have different opening areas, and by rotating the valve body 16, any one of the communication holes 17 can be brought into alignment with the second ventilation hole 13. Further, a housing 18 that is coaxial with the valve body 16 and covers the valve body 16 is attached to the seat frame 3.
This housing 18 has a third ventilation hole 1 on the same axis as the second ventilation hole 13.
9 is formed. Further, an operating handle 20 for rotating the valve body 16 about its axis is provided, and the operating handle 20 passes through the housing 18 and is screwed to the valve body 16.

確保できるところであれば良い。 When adjusting the flow rate of air flowing through the second ventilation hole 13 using the flow rate adjustment valve 15, each flow hole 1
7, a communication hole 17 having a desired opening area is selected and matched with the second ventilation hole 13. It is made to match the selected communication hole 13. This selected communication hole 17
If the opening area is large, the air flow rate at the second ventilation hole 13 will be large, and conversely, if the opening area is small, the air flow rate will be small. Therefore, by adjusting this air flow rate, the spring constant of the seat 1 using the cushion pad 4, the air pressure in the space 8, and the air pressure in the gap 10, that is, the stiffness of the seat 1, can be adjusted to the weight of the occupant, and the stiffness of the seat 1. It can be adjusted according to the passenger's preference. Moreover, in the above case, since the flow rate adjustment valve 15 is provided on the front surface of the seat 1, the flow rate adjustment valve 15 can be easily operated, which is advantageous. It should be noted that the flow rate regulating valve 15 may be placed not only in the front of the seat 1 but also in any place where a space for its operation can be secured.

迅速に復元する。 Further, in addition to the first ventilation holes 12, a separate ventilation hole may be formed in the seat frame 3, and a check valve that only allows air to flow into the space 8 from the outside may be attached to this ventilation hole. According to this configuration, when a load is applied to the seat 1, the air flowing out from the space 8 flows out of the space 8 only through each first ventilation hole 12. Further, when the cushion pad 4 restores its original position, air flows into the space 8 through each of the first ventilation holes 12 and the ventilation holes, so that the sheet 1 quickly restores its original position.

つて支持される。(Effect of the invention) According to this invention, a gap is formed in the seat frame, a space is formed between the seat frame and the cover covering the cushion member on the seat frame, and the gap and the space are communicated with each other. A first ventilation hole is provided, a second ventilation hole is provided that communicates the above-mentioned gap with the outside of the seat, and an adjustment means is provided to vary the opening area of the second ventilation hole, so that an impact load is applied to the seat by the seated person. When a load is applied, in addition to being supported by the cushion member, the load is also supported by the elasticity of the air in the space and also by the elasticity of the air in the gap, that is, by a sufficient amount of air. Supported.
よつて、着座者によりシートに衝撃的な負荷が
加えられたとき、上記空気の弾性変形による縮小

調整幅を広くすることができる。 Then, when the air is pressurized by the reduction of the air and is discharged through the regulating means provided in the second vent, a desired fluid resistance of the air can be obtained by the pre-adjusted opening area. As a result, the spring constant of the air in the gap and the space is adjusted, and in this case, since the original amount of air is large as described above, the adjustment range of the spring constant can be widened accordingly. .
よつて、上記衝撃が効果的に吸収されると共
