and side waist support exercise mechanisms provided on both sides of the seat plate 1.

The rotary supporting mechanism comprises horizontal supporting shafts 7 symmetrically connected to two sides of the U-shaped support 3, a rotary supporting cylinder 8 rotationally connected with the horizontal supporting shafts 7 through bearings, and a torsion spring 9 arranged in the rotary supporting cylinder 8 and sleeved on the horizontal supporting shafts 7, one end of the torsion spring 9 is fixedly connected with the horizontal supporting shafts 7, and the other end of the torsion spring 9 is fixedly connected with the rotary supporting cylinder 8;

the outer side of the rotary supporting cylinder 8 is connected with a fixed supporting ring 10 fixedly connected with the lower end of the backboard bracket 5.

The limiting mechanism comprises limiting slide blocks 11 symmetrically connected to two sides of the U-shaped support 3 and arc-shaped slide ways 12 arranged on the side surfaces of the rotary supporting cylinders 8 and used for accommodating the limiting slide blocks 11 to slide.

The braking mechanism comprises upper hole grooves 13 symmetrically arranged on two sides of the lower surface of the backboard 6, sliding limiting rods 14 assembled in the upper hole grooves 13 and lower hole grooves 15 arranged on the upper end surface of the U-shaped bracket 3 and used for accommodating the sliding limiting rods 14 to be inserted;

vertical limiting openings 16 communicated with the upper hole grooves 13 are symmetrically formed in two sides of the rear surface of the back board 6, and sliding blocks 17 sliding in the vertical limiting openings 16 are connected to the upper ends of the side surfaces of the sliding limiting rods 14.

The side waist support exercise mechanism comprises seat armrests 18 symmetrically connected to two sides of the seat board 1, a side waist support exercise roller 19 sleeved on the seat armrests 18, and an anti-slip sleeve 20 sleeved on the seat armrests 18 and located in front of the side waist support exercise roller 19.

A cushion 21 is laid on the upper surface of the seat board 1.

The lower end faces of the supporting legs 2 which are supported and connected at the four corners of the lower surface of the seat board 1 are all connected with anti-skid pads 22.

The upper surface of the backrest plate bracket 5 is wrapped with a neck cushion 23.

The back lumbar support exercise roller 4 is a sponge soft roller.

The side waist support exercise roller 19 is a sponge soft roller.

The working principle is as follows:

in the process of using the device, at first bedplate 1 and landing leg 2 constitute conventional seat and use, and the user sits on bedplate 1 that is equipped with cushion 21, utilizes landing leg 2 to support, and cushion 21 plays the effect that improves the travelling comfort. When the user need carry out the lumbar vertebrae and take exercise, the back lumbar support that at first utilizes U type support 3 to support back waist by utilizing cylinder 4 to take exercise to back lean on backward, and the lumbar vertebrae of waist formula is taken exercise down in the support of back lumbar support taking exercise cylinder 4, and wherein back lumbar support takes exercise cylinder 4 and is the soft cylinder of sponge, improves the travelling comfort when taking exercise. When the body leans back, the back board bracket 5 and the back board 6 are inclined backward along with the body, and during the sitting straight of the body, the back board bracket 5 is restored to the original position by the rotation support mechanism to perform the subsequent lumbar exercise action. Specifically, during the process that the backboard support 5 and the backboard 6 are inclined backward along with the body, because the backboard support 5 is fixedly connected with the rotating support cylinder 8 through the fixed support ring 10, and the rotating support cylinder 8 is supported by the horizontal support shaft 7, the relative rotation between the horizontal support shaft 7 and the rotating support cylinder 8 is realized through the bearing, and because the torsion spring 9 is connected between the horizontal support shaft 7 and the rotating support cylinder 8, the rotating support cylinder 8 is driven to rotate during the process that the backboard support 5 is inclined backward along with the body, so that the torsion spring 9 stores the force, and during the subsequent process that the body of the user is sitting straight, the torsion spring 9 drives the rotating support cylinder 8 to rotate reversely, and then the backboard support 5 and the backboard 6 are driven to return to the initial positions. In the process of backward leaning of the body of the user, the torsion spring 9 also provides a reverse acting force for the backrest plate bracket 5 and the backrest plate 6 while accumulating force, so that the backrest plate bracket 5 and the backrest plate 6 also have a certain supporting effect on the body of the user, the lumbar vertebra is prevented from being injured by sudden waist descending of the user, and the auxiliary exercise effect is further realized. Meanwhile, in the rotating process of the backboard support 5 and the rotating support cylinder 8, the rotation angle of the backboard support 5 and the rotating support cylinder 8 is limited by the limiting mechanism, so that the phenomenon that the lumbar is injured due to the fact that the user cannot control the body to move down when the user moves down is prevented from being too large in rotation angle. Specifically, in the process that the backboard support 5 drives the rotation supporting cylinder 8 to rotate, the limiting slide block 11 in the limiting mechanism slides along the arc-shaped slide way 12, the sliding path of the limiting slide block 11 is limited by the limiting length of the arc-shaped slide way 12, then the rotation angle of the supporting cylinder 8 is limited, and then the backward rotation angle of the backboard support 5 is also limited. When the back lumbar support exercise is not needed, the back board bracket 5 is braked to rotate by the braking mechanism, so that the back board bracket cannot rotate. Specifically, the sliding block 17 is moved to slide up and down along the vertical limiting opening 16, then the sliding limiting rod 14 in the upper hole groove 13 is driven to extend out, the sliding limiting rod is inserted into the lower hole groove 15 on the U-shaped support 3, then the back board support 5 is braked in a rotating mode, and then the sliding limiting rod 14 is completely retracted into the upper hole groove 13 to brake when back lumbar support exercise needs to be carried out. The user can also use the side waist support exercise mechanism to carry out the lower waist type exercise of the side waist. Specifically, support through the side waist on the armrest 18 supports and tempers cylinder 19 and carries out the support of side waist, accomplishes the lower waist action of side waist, and wherein the side waist supports and tempers cylinder 19 for the soft cylinder of sponge, improves the travelling comfort when taking exercise, and this in-process, the user supports to support through antiskid cover 20 on the armrest 18 and assists in, and the in-process that lets the user take exercise at the side waist is safer. Wherein the anti-skid pad 22 plays an anti-skid role for the whole device, so that the supporting of the supporting leg 2 to the seat board 1 is more stable. The neck rest 23 allows the user to lean on the neck rest 23 during the reclining process, which increases the comfort of use.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
