Depending on the embodiment, the plates 60a-2 and 60b-2 may include a plurality of holes spaced apart at predetermined intervals. The hole may have an elliptical shape, but the present invention may also be applied to other shapes such as a circular shape or a rectangular shape.

In the case of the present invention, by implementing the hole, ventilation is ensured, so that even if a user who does not move much or has difficulty in movement is located in the lifting device 1 for a long time, the amount of sweat shed by the user is reduced or the sweat is easily discharged. There will be an advantage.

A first coupled portion 41 may be formed on each of the two backrest members 60a and 60b. Specifically, the two backrest members 60a and 60b may be formed to face each other at one end (eg, lower end) of one side (inner side) of each. That is, the first coupled portion 41 is provided at one end (eg, lower end) of the right side of the first backrest member 60a and at one end (eg, lower end) of the left side of the second backrest member 60b, respectively. They may be formed opposite each other.

Each of the two first coupled parts 41 may be coupled to the two first coupling parts 31 of the seat part 50 to couple and fix each of the two backrest members 60 to the seat part 50. .

Referring to FIGS. 9A and 9B , the angle between the back member 60 and the horizontal plane (the plane formed by the X and Y axes) and the back member 60 (θ ₁ ) in a state in which the back member 60 is coupled to the seat portion 50 When going from (a) lying mode to (c) standing mode, it can be tilted from about 0 degrees to about 90 degrees. (For reference, in (a) of FIG. is 0 degrees, so θ ₁ is not indicated)

The seat portion 50 is formed in a plate shape so that a user can sit on it, and is coupled to the backrest portion 60 through two first coupling portions 31 and a leg through two second coupling portions 32. It can be combined with part 70.

Depending on the embodiment, the two first coupling portions 31 and the two second coupling portions 32 may be formed on both sides of the seat portion 50 . Specifically, one first coupling portion 31 and one second coupling portion 32 are formed at a predetermined distance apart from one side of the seat portion 50, and the other first coupling portion 31 and the other second coupling portion 32 are formed. The two coupling parts 32 may be formed on the other side of the seat part 50 at a predetermined distance apart.

The seat portion 50 is coupled to the leg portion 70 through the two second coupling portions 32 and the two second coupled portions 42, so that the height H of the leg portion 70 increases in the vertical direction. When adjusted to, accordingly, the height of the seat portion 50 can also be adjusted together.

The leg portion 70 may be coupled to both side surfaces of the seat portion 50 to support the seat portion 50 .

The leg part 70 may support the weight of a user seated on the seat part 50 .

The leg part 70 may include two leg members 70a and 70b. The two leg members 70a and 70b are formed with second coupled portions 42, respectively, and through the coupling of the two second coupled portions 42 with the two second coupling portions 32, the leg portion ( 70) may be coupled to the seat portion 50.

The second coupled parts 42 are formed at one end (eg> upper end) of one side surface (eg> inner surface) of the two leg members 70a and 70b to face each other with respect to the central axis z, respectively. , Each second coupled portion 42 is coupled to each second coupling portion 32 so that the leg portion 70 is coupled to the seat portion 50 to support the seat portion 50 .
