Claims

1. A rehabilitation chair, characterized in that: It includes an upper frame, a lower frame, a telescopic device, and a control device. The upper frame is for people to sit on. The lower frame is located below the upper frame. The bottom of the upper frame is hinged to the top of the lower frame, allowing the upper frame to swing back and forth on the lower frame around the hinge. The telescopic device is located between the lower frame and the upper frame. The extension and retraction of the telescopic device can cause the upper frame to swing forward or backward on the lower frame around the hinge, thereby causing the person sitting on the upper frame to lean forward or backward. The control device is used to control the extension or retraction of the telescopic device.

2. The rehabilitation chair as described in claim 1, characterized in that: The upper frame has a seat area and a backrest area. The seat area extends horizontally forward and backward, and is used for the human buttocks to sit on. The backrest area extends vertically and is located at the rear of the seat area, and is used for the human back to rest against.

A rehabilitation chair as described in claim 2, characterized in that: The front and rear edges of the bottom of the seating area are respectively equipped with a first connecting rod and a second connecting rod extending to the left and right. The upper end of the lower frame is hinged to the first link, which swings back and forth. The lower frame has a third link that extends left and right, located below the first link. The two ends of the telescopic device are hinged to the third link and the second link, respectively, which swing back and forth. When the telescopic device extends, it can push the second link upward and swing forward around the first link, so that the rear end of the seat area and the backrest area swing forward about the first link as the axis, thereby causing the person sitting in the seat area to lean forward. When the telescopic device retracts, it can pull the second link downward and swing backward around the first link, so that the rear end of the seat area and the backrest area swing backward about the first link as the axis, thereby causing the person sitting in the seat area to lean backward.

4. A rehabilitation chair as described in claim 3, characterized in that: The control device includes a control box and a remote control. The control box is located on the rear side of the backrest area. The control box contains a PCB board and a power supply. The PCB board and the power supply are electrically connected to the telescopic device. The PCB board is also connected to the remote control, which controls the extension and retraction of the telescopic device.

5. A rehabilitation chair as described in claim 3, characterized in that: An arm is provided on the front side of the lower frame. The upper end of the arm is fixed to the first link, and the lower end of the arm extends downward. A foot pedal is hinged at the end of the extension. The foot pedal can be flipped upward or downward to a horizontal position with the hinge point as the axis.

6. A rehabilitation chair as described in claim 3, characterized in that: The lower frame includes two first supports extending vertically. The upper ends of the two first supports are respectively hinged to the left and right ends of the first connecting rod. The left and right ends of the third connecting rod are respectively connected to the first supports and the second supports. The pulleys are installed at the lower ends of the two first supports. The second supports extend backward from the upper ends of the first supports. The pulleys are installed at the extended ends of each second support. An arc-shaped fixed bracket is provided on each second support. One end of the fixed bracket is connected to the middle of the second support, and the other end is connected to the first connecting rod.

7. A rehabilitation chair as described in claim 3, characterized in that: The upper part of the backrest area is equipped with handrails for people to use to move the rehabilitation chair.
