Of course, the upper body fixing mechanism 50 described above is applicable to the case of exercising using the upper body, although not separately illustrated in addition to the exercise using the lower body as described above.

Next, the center of motion of the back frame (6) in the case of performing the lower back exercise using the upper body in order to prevent the phenomenon that the body does not match the rotational operation center of the exercise device and do not have a sense of unity with the exercise device during compliance When the lower back is exercised using the lower body and the lower body is used, the central axis of movement of the knee hook 9 is configured to be consistent with the hip joint, or the central axis of the knee is configured to be consistent with the hip joint through the interlocking member. 5, which corresponds to the former of which the hinge portion 13 provided on the fixed frame 11 coincides with the lumbar region, as the example shown in FIG. As an example of the technical configuration, in the example shown in Fig. 13, the upper and lower straight lines connecting the centers of the rotating gears 284 and 292 to each other as the center of motion of the knee hook 9 are virtual. Central axis 288 of the rear of the crosspiece 262 and the pivoting gear 284 so that the distance from the center of the hip 15 to the center of the knee rest 9 is always in line with the center 15 of the hip joint. By adopting the structure of the parallel link 289 as the interlocking member therebetween, the centers of motion are configured to coincide with each other, or as in the example shown in FIG. The center and the center of the hip joint can be configured to match each other.

Next, for example, in the case of the movement range adjustment mechanism 60 which is installed at the center of movement of the back frame 6 or the knee hook 9, or in conjunction with it, in order to adjust the movement range during extension and refraction exercise, 1, 4, 13, 16, and 19, the hinge portion 13 as the movement center axis or the central axis 288 of the rotation gear 284 as the movement center axis is When installed on the central axis 296 of the rotational gear 292, which is a rotational portion that is made to rotate the stopper (62, 62) is interlocked with the hinge portion 13 or the central axis (296) at one side reference position The rotating disk 61 is installed and the hinge portion 13 and the central shaft 296 are not interlocked, but are only inserted in an idle state, and the stopper 62 is fixed to the inside and fixed by the springs 68 and 68. It is installed in a rugged state and has a pair of adjustment knobs (63, 63) for adjusting the range of motion. Long holes (66, 66) for adjusting the range and a plurality of fixing grooves (67, 67) formed at a predetermined interval in each of the holes (66, 66), respectively, and the adjustment knobs (63, 63) are the long holes (66), respectively. , 66 may be configured in the form of a combination of the outer casing 65 is fixed to the chair body 1 so as to be exposed to the outside via the light. Thus, by using the adjustment knobs (63, 63) in each of the various fixing grooves (67, 67) in the range provided in the long holes (66, 66) to set the range of motion of both sides of the hinge portion (13) or the range of motion is limited to the position where the stoppers 62 and 62 of the rotating disk 61 interlocked with the central axis 296 are inserted into the fixing recesses 64 and 64 to be fixed. The exercise category of the frame 6 or the knee-rest 9 is determined. Of course, the above-described adjustment knob (63, 63) or long hole (66, 66) may be formed only on one side can be configured to control only the exercise category of one side.

In addition, the back frame (6) or the knee hook (9) is installed so as to interlock the manual drive mechanism with the load mechanism (8), it is possible to selectively perform the active movement or passive movement, In the case of active exercise, the exercise is performed according to the exercise load force obtained from the load mechanism 8 configured to adjust the load force by utilizing the user's physical strength, and during the manual exercise, even if the user does not apply the force, By the passive exercise force applied by the force to perform the user's lower back movement. Of course, in view of the user, in the case of the active load mechanism 8 described above, the load mechanism 80 according to the present invention described below or other conventional weight, spring, elastic rubber material, independent shock absorbers (Shock Absorber), etc. may be used, and in the case of the manual driving mechanism, the user does not apply force such as a driving motor by an electric operation method, a driving cylinder operated by oil or pneumatics, and other external personnel. If not, it is configured to be operated by a passive forced load applied by a third party from the outside, for example, the handle lever 74, the media supply and control mechanism 87, which will be described later, etc. This is so.

At this time, in the case of the exercise load force obtained by the load mechanism 8, the exercise load force actually experienced by the user is not transferred to the exercise load force by the pure load mechanism 8, but rather the back frame 6 or the knee.
