Referring to FIGS. 1 to 3, a lower body exercise apparatus 100 is mainly ergonomically designed, and is integrally assembled with the chair seat 200 to operate the lower body to train a user. It has a motion assembly 300 that can be performed repeatedly.
4 to 6 show the chair seat 200 in an enlarged manner.

  Referring to FIGS. 4 to 6, the chair seat 200 designed according to the present invention considers the curve of the buttocks of the user who sits down to exercise the lower body, and also balances the weight according to the exercise execution operation. It is ergonomically designed so that it can be distributed to When the user sits on the chair, the chair will support the user's buttocks, because the chair and buttocks push away from each other. Therefore, it is preferable that the chair seat is designed so that the user's buttocks can smoothly enter and exit, and do not come up and adhere when sitting on the chair seat. If the user performs high-intensity exercise while the user's hips are not in close contact with the chair seat, the user feels severe pain beyond the stiffness of the buttocks, and in some cases, even feels that his feet are numb. In conclusion, the ergonomic design of the chair seat is important.

  Therefore, according to the present invention, the chair seat 200 is ergonomically designed, but when viewed with reference to the upper surface of the chair seat, the first segment 211, the second segment 212, and the third segment 213 are used. However, the first segment 211 and the second segment 212 are connected to a smooth curved surface. At this time, the radius of curvature of the first segment 211 is smaller than the radius of curvature of the second segment 212.

  When the user sits on the chair seat 200, the first segment 211 is a position where the pelvic region below the coccyx of the user sits down. The center of the first segment 211 is formed so as to smoothly enter a depth of about 1 to 3 cm below the edge, and takes into account the shape of the buttocks of the user sitting on the chair seat 200. It is smoothly curved upward from the part to the edge. With such a shape, the weight of the user is evenly distributed at the center of the ischial tuberosity (hip bone) located in the first segment 211.

  When the user sits on the chair seat 200, the front part and the thigh part of the user's hips are seated on the second segment. Similar to the first segment 211, the center of the second segment 212 is formed so as to smoothly enter a depth of about 1 to 3 cm below the edge, and the bottom of the user sitting on the chair seat 200. Considering the shape of the part, it is smoothly curved upward from the center to the edge. At this time, since the radius of curvature of the second segment 212 is larger than the radius of curvature of the first segment 211, the second segment 212 is formed to be flatter than the first segment 211. The second segment 212 extends to the front frame of the chair seat 200 through the left and right sides of the third segment 213 so as to surround the third segment 213. When viewed on the horizontal plane of the chair seat 200, the front frame 212a of the second segment 212 is formed lower than the rear frame 211a of the first segment 211.

The third segment 213 is formed so as to protrude upward by a predetermined height in front of the second segment 212 so as to face the first segment 211. When the user sits on the chair seat 200, the third segment 213 is touched by the inner region of the user's thigh. At this time, the lower part of the user's thigh is seated on the left and right second segments 212 of the third segment 213. A flat upper lid portion 214 is formed between the upper boundary of the third segment 213 and the front frame of the chair seat 200. A recess 220 is formed below the upper lid portion 214 and the third segment 213 for receiving the motion assembly 300.

Then, the inward part of the user's thigh is brought into close contact with the third segment 213.

  Due to the shape and structure of the ergonomic chair seat 200, the pressure acting on the user's ischial tuberosity is appropriately distributed and the buttocks are fixed, providing the user with a comfortable sitting comfort and reducing fatigue. I do. In addition, the pressure on the thigh, which is subjected to the next largest load after both ends of the ischial tubercle when exercising, is reduced by appropriate dispersion, and the pressure applied to the local part and the coccyx is minimized, as well. It has a great effect on improving comfort, reliability and safety.

  While sitting on the chair seat 200, the user operates the handle 312 of the operating rod 330 to adjust the exercise load. That is, when the handle 312 of the operating rod 330 exposed to the front and outside of the chair seat 200 is turned clockwise or counterclockwise, the connection block 334 moves forward or backward along the guide rail 311. Since the arm 324 and the compression member 340 are connected to the 334 via the extension spring 322, the exercise load is adjusted by adjusting the tension of the extension spring 322 by adjusting the position of the connection block 334.

After adjusting the exercise load to the desired state, the user places the thigh with the outer surface of the compression member 340 integrally connected to the rear end of the arm 324 touching the inside of the thigh of the user.
