た押上げ力が得られる。That is, the slide guide 21 is provided with a large number of engaging portions 22 for receiving a force point, which is the other end portion of the gas spring 19, in the longitudinal direction. The gas spring 19
Is slightly stretched, the push-up force is weakened by the change of the power point, and it is suitable for a lightweight person. If it is set backward as shown in FIG. 3, the gas spring 19 is in a shortened state, and the push-up force is changed by the change of the power point. It becomes stronger and is more suitable for heavy people. Therefore, by selecting the position of the engaging portion 22 in accordance with the weight of the user, a lifting force suitable for the user can be obtained.
【００１５】ガススプリング１９の伸長は前記肘掛け４

知のようにそのロックが制御されるようになっている。The gas spring 19 is extended by the armrest 4.
By operating a lever 23 provided on the lower side of the front end, the lock is controlled as is well known.

では前後リンク８，１６とも水平状態におかれている。First, in the seated state, as shown in FIG. 1, the rear seat 7 is positioned without a step behind the front seat 6, and both of them are kept in a horizontal posture. Similarly, the user can be seated, and when the user does not need the assist for standing up, the user can rise from the seated state to the standing state without operating the lever 23. In this seated state, the front and rear links 8, 16 are both in a horizontal state.

傾状態に上昇させる。When the occupant needs to stand up and stand up with the feet on the floor and need assistance in standing up, simultaneously grasp the tip of the left and right armrests 4 and 4 and the lever 23, and
Is operated, the valve of the gas spring 19 is unlocked, and the gas spring 19 is extended as shown in FIG. 2 and the rear seat portion 7 is slightly raised forward so as to follow the standing of a seated person. Let it.
【００１９】この上昇に伴い後リンク１６は軸１７を支
点として上昇するように回動するが、後リンク１６と前
リンク８は平行リンクの関係になっているため前リンク
８も後リンク１６に連動して上昇する。With this rise, the rear link 16 rotates so as to rise with the shaft 17 as a fulcrum. However, since the rear link 16 and the front link 8 are in a parallel link relationship, the front link 8 is also connected to the rear link 16. It rises in conjunction with it.
【００２０】このため前リンク８の上部にある前座部６

できる。For this reason, the front seat 6 above the front link 8
Is bent about the hinge 14 at the front end of the rear seat 7 and leans forward so as not to hinder the natural standing posture of a person standing up. If the lever 23 is released, it is fixed at that position, so that it is possible to return to the standing operation from that position.
【００２１】再び着座する場合には上記とは逆の作動に

痛を与えることはない。When the user sits down again, the posture is changed from the upright posture to the sitting posture smoothly by the operation opposite to the above. That is, when the lever 23 is operated, the lock of the valve of the gas spring 19 is released, so that the gas spring 19 sequentially contracts according to the weight received when the user sits down on the rear seat portion 7, and the chair main body 1 becomes as shown in FIG. Therefore, the user can sequentially return from the state of sitting on the chair body 1 to the seated posture, but no pain is given to the user in this process.

る。In the case of FIGS. 3 and 4, standing and sitting can be performed by the same operation as described above, but as shown in FIG.
By locking the upper end of the gasket 9 to the rear engaging portion 22, the reaction force when the lock of the gas spring 19 is released increases, so that even a person with a large weight can sit smoothly.
