Embodiment 1
[0015] Example 1: Seats such as figure 1 As shown, the bow-shaped support is combined with a seat and a footrest to form a dual-purpose office chair for sitting and sleeping. Guide rail is installed on the inner side of foot support plate, when changing from sleeping state to seat state, the wheel of rotation exerts a backward force to guide rail, and guide rail drives foot support plate to rotate around the axis and stop at the inner side of vertical plane. This embodiment is simple in structure, but the seat height cannot be adjusted. During specific implementation, it can be made into a series of chairs with different seat heights, so that the user can select a seat with a suitable height when purchasing.
Embodiment 2
[0016] Embodiment 2: change the bow support in Embodiment 1 into figure 2 The rest of the shown bracket with adjustable seat height is exactly the same as that of Embodiment 1. One end of the seat height adjustment screw is pushed against the iron plate of the base, and the support rod moves up and down in the casing by rotating the ball head of the seat height adjustment screw, so as to achieve the purpose of adjusting the seat height. Also change the square support rod to a round or pneumatic rod, but this requires an additional device to prevent the seat from rotating.
