However, the spirit of the present invention is not limited thereto. The chair 1 according to an embodiment of the present invention may be a patient chair used for physical assistance of a patient who must live in a bed due to trauma, illness or the like.

The leg portion 100 can support the body portion 200 including the seat member 210 and the user can sit on the seat member 210. As an example, the seat member 210 may be constructed of air mesh fabric. Thereby, the user can be prevented from sliding from the seat member 210, a superior cushioning feeling can be provided, and the user's body pressure can be effectively dispersed.

At this time, an armrest part 300 to which a user's arm can be supported and a backrest part 400 to which a user's back can be supported can be connected to the body part 200. The armrest portions 300 may be provided on both sides of the body portion 200 in pairs.

On the other hand, the height of the armrest portion 300 and the backrest portion 400 can be adjusted in stages. Since the height of the arm part 300 is independently adjusted on both sides of the body part 200, the user can freely adjust the height of the arm part 300 according to the required operation.

Also, the armrest portion 300 and the backrest portion 400 are detachable from the body portion 200 according to the user's physical condition. For example, when a large part of the body of the user is required to be handled, both the armrest portion 300 and the backrest portion 400 can be connected to the body portion 200 and used.

Alternatively, at least one of the armrest part 300 and the backrest part 400 may be separated from the body part 200 when the user needs to take care of a certain part of the user's body so as to reduce the weight of the chair 1 .

To this end, at least one of the armrest portion 300 and the backrest portion 400 includes a first moving frame member 310, a second moving frame member 320, a pull member 330, and a button member 340 .

The first movable frame member 310 can be inserted into the body part 200 so as to be movable in the vertical direction. Here, the vertical direction means the y-axis direction in Fig.

To this end, a plurality of first guide grooves 312 may be formed on one surface of the first movable frame member 310. For example, a connection groove 313 may be formed between any one of the first guide grooves 312 and the adjacent one of the first guide grooves 312, As shown in Fig.

A groove 314 may be formed at a lower end of one surface of the first movable frame member 310. By this groove 314, the first movable frame member 310 can be easily inserted into the body portion 200. This will be described later.

A fixing bracket 315 may be provided between the end of the first moving frame member 310 and the pull member 330. In this case, the fixing bracket 315 may be formed to protrude to both sides of the first movable frame member 310.
