The aim of the invention is to increase the effectiveness of training by expanding the types of exercises performed.

FIG. 1 shows a chair, side view; in fig. 2 - the same, front view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; in fig. 5 shows a section B-B in FIG. four; in fig. 6 is a cross-section of the FIG. four; in fig. 7, 8 and 9 - performed exercises on the chair; in fig. 10 — node I in FIG. eight; in fig. 11 - section DD in FIG. ten; in fig. 12 — node AND in FIG. one; in fig. 13 is an example of a workplace layout using a training chair.

The seat contains (figs. 1, 2 and 3) base 1, seat 2, back 3, tubular armrests 4, guide 5, support node 6 and U-shaped crossbar-7. The base 1 can be provided with means for turning and lifting the chair, made, for example, in the form of a support 8 with a screw 9 fixed on it and a base plate 10 with a machine 11 freely screwed on; and a screw 9. Fixing the position of the cup 11 on screw 9 can be provided with a latch 12 mounted on the glass 11. On the support 8, the leg support 13 is articulated and the seat 2 on the support plate 10.

The backrest 3 consists of a support frame 14 (FIG. 4), hingedly connected with the seat 2, a massage frame 15 and an arm 16.

The massage frame 15 is made with wavy protrusions 17 (Fig. 10) on the longitudinal sides. Inside it, on transverse axles 18 (Fig. 5), massage elements, such as rollers 19, are installed with the possibility of free rotation. By means of axles 20 (Fig. 4), the massage frame 15 is pivotally connected with armrests 4.

the strips 42 with grooves g are fitted with a U-shape, the crossbar 7 with a roller 44 for performing pushing. 3 h. the item of f-ly, 13 ill.

The hinged joints of the support frame 14 with the seat 2 (Fig. 12) are provided with clamps 21 consisting of sectors 22 mounted on the seat with grooves a for accommodating the latches 24 spring-loaded with springs 23 with handles 25. The latches 24 are movably mounted securely mounted on the support frame 14, sleeves 26 with protrusions 27 pressed against

handles 25.

In the middle part of the support frame 14 is fixed (Fig. 4) a bracket 16, by means of which the backrest 3 is hingedly connected with the armrests 4. The hinged connection of the support frame 14 with the armrests 4 is 5 formed in the form of a link 28, in the opening of which is mounted with the possibility of moving 5.

A compression spring 29 (fig. 1) is mounted on the rail 5, by means of which the backrest 3 is spring loaded.

0 of the backrest 3 with respect to the seat 2 is determined by the position of the guide 5 in the link 28 and is fixed by the lock 30 (Fig. 4). The latter is made in the form of spring-loaded fingers 31 installed in

5 with a link 28. With one end, the fingers 31 interact with the holes 6, made on the guide 5, and the other end are connected by means of flexible bars 32 with the arms of the 33 two-arm levers 34 (FIG. 6) that are hinged in the slots (FIG. four)

0 armrests 4.

In the upper part of the backrest 3, a support unit 6 is installed, consisting of the support plate 35 (Fig. 11), on one side of which the headrest 36 and the brackets 37 are reinforced with rollers 38 for interaction with the projections 17 of the massage frame, and on the other protrusions 39 for supporting the armpits of the athlete. By means of t g 40 (Fig. 9), the support unit 6 is hingedly connected to the support frame 14 of the backrest 3.

0 The ends of the upper part of the support frame 14 of the backrest 3 are hingedly attached to the clamps 41 (Fig. 9), in which the U-shaped crossbar 7 stands are movably mounted. The crossbar 7 is fixed relative to the backrest 3 due to the mutual action of the struts crossbar with grooves g slats 42, rigidly mounted on the support frame 14. Racks U-shaped crossbar 7 provided with stops 43 (Fig. 9 and 7).

On the transverse part of the U-shaped crossbar, roller 44 can be rotatably mounted.

The chair is used taking into account the possibility of making several variants of the layout of its elements depending on the requirements.

The chair shown in FIG. 1, can be used as a workplace when performing any work and a place of passive or active recreation. During operation or passive rest, the soft surface of the head restraint 36, when the support unit 6 is installed above the support frame 14, is a support for the head, and when it is lowered onto the backrest 3 (Fig. 9), when the support plate 35 closes the massage frame 15, soft back support. A comfortable sitting position for the backrest 3 is established by pressing the fingers 33 on the handle 33 of the levers 34 and the subsequent back pressure on the back of the 3 chairs. In this case, the fingers 31 are pulled out of the holes 6 of the guide 5 and it slides freely in the opening of the link 28. The backrest 3 at the same time is unhindered and deflected to the desired position and fixed in this position by returning the handle 33 to its original position, with the result that the fingers 31 enter into the corresponding holes of the guide 5. The backrest 3 returns to the vertical position in the same way with the help of the spring 29.

The distance between the seat 2 and the floor is adjusted by rotating the cup 11 along the screw 9 and secured by the lock 12 (Fig. 2).

If necessary, the U-shaped crossbar 7 can be moved down under the seat 2 (Fig. 7), for which its ends should be pulled out of the grooves r and turned around the axis of the hinged connection of clamps 41 with the support frame 14 and lowered the U-shaped crossbar 7 way down. The withdrawal of the ends of the crossbar 7 from the holes of the clamps 41 is prevented in this position by the stop 43.

With active rest, the considered chair layout allows you to do a number of exercises, for example, to unload the spine by resting your armpits on the protrusions 39 while the supporting unit 6 is lowered on the back 3 or on the crossbar 7 in the seat. By lifting above the back of the 3 support unit 6, a back massage can be performed. To do this, the sitting person needs to press his back against the massage frame 15 and bring it into reciprocating motion by moving the arms 4 up and down with his hands. Rollers 19, rolling over the back, are massaged.

The chair shown in FIG. 7, can also be used as work

which places and simulator for performing physical exercises. To obtain this layout, the elements of the latch 24 with the handles 25 (Fig. 12) are rotated so that the latter slide from the protrusions 27 and press against the sectors 22. By moving the armrests 4 up (or lowering the backrest 3 back), they achieve the grooves a of the sectors 22. In this case, the backrest 3 and the seat 2 are located in the same plane. The required inclination of the backrest 3 with the seat 2 is made by moving the guide 5 in the connecting rod 28 in the same way as the installation of the required inclination of the backrest 3. The position of the backrest 3 with the seat 2 shown in FIG. 7 allows the use of an exercise chair with an inclined plane. So, training, hooking the feet with the supporting unit 6 lowered to the back 3, deflects the torso back and then returns to its original position. This layout of the chair can also be used to work in a half-shaped posture with the pelvis resting on the seat 2.

In the vertical position of the backrest 3 with the seat 2 (Fig. 9), the spine can be unloaded by resting the armpits on the protrusions 39 or by grasping hands on the top of the crossbar 7. Moreover, the armrests 4 can be used as bars, and on the roller 43 P- With the figurative crossbar 7, it is possible to throw up a flexible pull with a load (or without it) and perform various strength exercises. You can also hang a punching bag or other equipment on the transverse part of the crossbar 7.

This layout of the chair (Fig. 9) can also be used as a workplace when the layer is working (for example, the designer’s workplace at the drawing board of Fig. 13) with the back resting on the anchor unit 6 and the pelvis on the seat 2.

The layout of the chair elements shown in FIG. 8, is used for vibratory massage, for example, feet. For this, the support unit 6 is lowered onto the massage frame 15. When the armrests 4 move forward and backward, the massage frame 15 pivotally connected to them comes in reciprocating motion, with the result that the rollers 38 of the support node 6, moving along the wave-like projections 17, create enough tangible vibration of the support unit 6 and, therefore, placed on it sitting.

This layout of elements, when lifted from the massage frame 15, the support unit 6, can be used as a treadmill or for foot massage. The U-shaped crossbar 7 is in this case a support for the arms. In addition, when the foot is fixed on the anvil 13, the trainees may load the abdominal muscles by deflecting the torso backward with sagging in the form and then returning to the starting position. The layout of the workplace, for example, a designer using a chair-trainer is shown in FIG. 13, where the chair is placed with the possibility of working on it at the table 45 and at the coommer 46.
