The back support bracket 32 of the pivot mechanism 30 has an upper end provided with a mounting sleeve 321 for mounting the back cushion 60. The back support bracket 32 of the pivot mechanism 30 is provided with two pivot members 33 and 34 pivotally mounted on the main frame 1, and the pivot mechanism 30 further includes two bushings 35 each mounted between the main frame 1 and a respective one of the two pivot members 33 and 34 of the back support bracket 32. The two pivot members 33 and 34 of the back support bracket 32 are rotatably mounted on the two mounting shafts 111 and 112 of the support post 11 respectively.

The arm support bracket 31 of the pivot mechanism 30 has a substantially U-shaped profile and has two opposite ends each provided with a mounting plate 312 for mounting a respective one of the two armrests 50. The arm support bracket 31 of the pivot mechanism 30 has a side provided with a fixing plate 311 for fixing the waist cushion 40. The arm support bracket 31 and the back support bracket 32 of the pivot mechanism 30 are combined to form a substantially L-shaped structure.

In operation, referring to FIGS. 4 and 5 with reference to FIGS. 1-3, the two pivot members 33 and 34 of the back support bracket 32 are pivotally mounted on the two mounting shafts 111 and 112 of the support post 11 respectively so that the pivot mechanism 30 is pivoted on the main frame 1, and is moved relative to the seat 20. In such a manner, when a user is seated on the seat 20 with his/her back resting on the back cushion 60 and with his/her back arms holding the two armrests 50, he/she can apply a force on the back cushion 60 to pivot the pivot mechanism 30 backward and forward as shown in FIGS. 4 and 5 so as to extend and retract the user's waist and back, thereby achieving an exercising or rehabilitating function.

Referring to FIGS. 6 and 7, the rehabilitation exercising equipment further comprises a transmission mechanism 70 mounted between the main frame 1 and the pivot mechanism 30. The transmission mechanism 70 includes a drive geared member 36 connected with the pivot mechanism 30 to move in concert with the pivot mechanism 30, a drive unit 80 mounted on the main frame 1, a driving geared member 81 rotatably mounted on the drive unit 80, and a linking member 90 mounted between the driving geared member 81 and the drive geared member 36 to link the driving geared member 81 and the drive geared member 36.

The drive geared member 36 of the transmission mechanism 70 is secured on moved in concert with one of the two pivot members 33 and 34 of the back support bracket 32 and is rotatably mounted on one of the two mounting shafts 111 and 112 of the support post 11. The drive unit 80 of the transmission mechanism 70 is located between the support bar 10, the support post 11, the support rod 12 and the connecting rod 13. The drive unit 80 of the transmission mechanism 70 is electrically connected to and controlled by the control panel 26 of the main frame 1.

Alternatively, each of the driving geared member 81 and the drive geared member 36 is a sprocket, while the linking member 90 of the transmission mechanism 70 is a chain.

In operation, when the drive unit 80 of the transmission mechanism 70 is a magnetically controlled resistance device, the drive unit 80 provides a damping force to the driving geared member 81 and the drive geared member 36 by connection of the linking member 90 to damp rotation of one of the two pivot members 33 and 34 so as to provide a resistance to the pivot mechanism 30 so that the user has to apply a larger force to pivot the pivot mechanism 30 relative to the main frame 1, thereby enhancing the exercising or rehabilitating effect. At this time, the damping force of the drive unit 80 is controlled by the control panel 26 of the main frame 1.

Alternatively, when the drive unit 80 of the transmission mechanism 70 is a powered motor, the drive unit 80 drives the driving geared member 81 which drives the linking member 90 which drives the drive geared member 36 which drives one of the two pivot members 33 and 34 so that the pivot mechanism 30 is driven by the drive unit 80 and is pivoted on the main frame 1 so as to achieve a rehabilitating function automatically.

Accordingly, when a user is seated on the seat 20, he/she can apply a force on the pivot mechanism 30 to pivot the pivot mechanism 30 backward and forward so as to extend and contract the user's waist and back, thereby achieving an exercising or rehabilitating function. In addition, the drive unit 80 of the transmission mechanism 70 functions as a magnetically controlled resistance device to provide a damping force to the pivot mechanism 30 so that the user has to apply a larger force to drive the pivot mechanism 30, thereby enhancing the exercising or rehabilitating effect. Further, the drive unit 80 of the transmission mechanism 70 functions as a powered motor to drive the pivot mechanism 30 so that the pivot mechanism 30 is driven by the drive unit 80 and is pivoted relative to the main frame 1 so as to achieve a rehabilitating function automatically.
