[0029] The following combination Figures 1-8 The utility model is described in detail.

[0030] Example

[0031] A chair for exercising the back includes a seat cushion 2, the seat cushion 2 is connected to a support column 6, an arc frame 4 is connected to the support column 6, an arc frame 4 is provided on the back of the arc frame 4 with an arc slot 401, a spring 402 is provided in the arc slot 401, a baffle 403 for blocking the movement of the arm is movably provided in the arc slot 401, and the baffle 403 is driven by the arm to move along the arc slot 401 and squeeze the spring 402.

[0032] A person leans on the arc frame 4, places both hands on the back of the arc frame 4 and pushes the baffle 403 to move. During the movement of the baffle 403, the chest cavity can be opened and the spine can be stretched, thereby exercising. After the baffle 403 moves, it squeezes the spring 402 to generate a reverse thrust, thereby increasing the intensity of the exercise. The compressed spring 402 can also help the baffle 403 to reset, making it convenient for the next exercise.

[0033] The baffle 403 can be connected to a slider slidably disposed in the arcuate slot 401, directly compressing the spring 402 through the slider; however, to reduce wear, the sliding method is replaced with a rolling method. Specifically, a roller frame 406 is disposed in the arcuate slot 401, and the roller frame 406 is rotatably connected to at least two rollers 407. A connecting rod 405 connected to the baffle 403 is disposed on the side wall of the roller frame 406, and an abutment block 408 is disposed on the side of the roller frame 406 near the spring 402. The baffle 403 pushes the roller frame 406 to move via the connecting rod 405. The abutment block 408 at the end of the roller frame 406 guides the spring 402, ensuring that the roller frame 406 can better compress the spring 402.

[0034] There are at least two support columns 6, a fixing block 9 is fixed between the two support columns 6, a first knob screw 8 is threaded on the fixing block 9, a first slide groove 601 is vertically provided on the side of the support column 6 close to the arc frame 4, a first slider 404 is provided on the arc frame 4 to slide with the first slide groove 601, and an abutment seat 10 is provided on the back of the arc frame 4 to extend between the two support columns 6 and tightly cooperate with the first knob screw 8 to fix the arc frame 4.

[0035] The arc frame 4 can be vertically adjusted on the support column 6 by sliding the first slider 404 with the first slide groove 601. After adjusting the arc frame 4, tighten the first knob screw 8 and press the first knob screw 8 against the end face of the abutment seat 10 to limit the up and down movement of the arc frame 4.

[0036] Second slide grooves 602 are vertically provided on opposite sides of the two support columns 6, and second sliders 11 are provided on both sides of the abutment seat 10 to slide in connection with the second slide grooves 602. The second slide grooves 602 and the second sliders 11 cooperate to further increase the stability of the arc frame 4 and prevent it from swinging.

[0037] The support column 6 is connected to a headrest 7 located above the curved frame 4. A mounting base 702 is fixed to the upper end of the support column 6. A slide plate 701, which is connected to the headrest 7, is vertically slidably mounted within the mounting base 702. A second knob screw 703 is threadedly mounted on the mounting base 702 and abuts against the slide plate 701. The headrest 7 helps the user rest their head and improves comfort. The slide plate 701 and the second knob screw 703 allow the height of the headrest 7 to be adjusted to suit different users.

[0038] Armrests 3 are provided on both sides of the seat cushion 2. The armrests 3 are used to place the user's arms to avoid fatigue caused by the arms being suspended in the air.

[0039] The support column 6 is connected with a back pad 5 located below the arc frame 4. The back pad 5 can support the user's waist and reduce the fatigue of the waist.

[0040] The bottom of the seat cushion 2 is connected to a movable bracket 1. This bracket facilitates the chair's mobility. It is equipped with several universal wheels equipped with brakes. A pneumatic rod (known in the art) is installed between the bracket 1 and the seat cushion 2 to adjust the height of the seat cushion 2.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
