In the automotive industry, when parts are mounted at a particular location on a vehicle, the human body needs to maintain a specific posture to complete the work. The workers need to keep standing and keep the upper body bent forwards at a certain angle, which brings great pressure to the muscles and the spine of the waist, easily causes muscle fatigue and spine damage, and causes diseases such as lumbago or lumbar prolapse. Maintaining such movements for long periods of time can result in occupational diseases that severely affect future health. For this reason, it is necessary to develop a corresponding protector to provide health care.

The waist load of the operator during bending can be reduced by adopting the mode of straightening waist and stretching knees to shorten the moment of rotation. In order to maintain the optimum working posture and the optimum working efficiency and to ensure a physiologically normal lumbar curvature, the inventors of the present application have conducted a great deal of research on a lumbar support device, see patent document CN209284357U, for example, of which fig. 1 shows a lumbar support band. The stooping limit belt comprises an upper body part, a lower body part and a waist part, wherein the waist part connects the upper body part and the lower body part together. The waist part comprises a fixed connecting belt 6, a difference compensation pulley 7 and a lumbar protection pad 8.

The lower body part comprises a connecting band 4, two lower body bands 3, two foot fixing connecting bands 14 and two foot fixing ring bands 5. The main function of the lower body is to receive the weight of the upper body, which is transmitted to the supporting points of the foot through the legs. The connecting belt 4 is connected to the two lower body belts 3 by bypassing the difference compensation pulley 7 arranged right below the fixed connecting belt 6, so that the belt length of the left leg and the right leg can be automatically adjusted, and the difference compensation effect is realized. The lumbar vertebra protection pad 8 is positioned on the reverse side of the fixed connecting belt 6 and used for enabling the lumbar vertebra to be stressed evenly and playing a role in buffering in the force exerting process, so that the lumbar vertebra is not damaged.

However, there are still some points to be improved in the stooping restraint strap described in CN209284357U, including for example: the upper body part and the waist part are combined and need to be connected through a complex connecting structure; the connecting belt of the lower body part is easy to fall off from the difference compensation pulley; the connection between the foot fixing connecting belt and the foot is not firm enough; the connecting band of the lower body portion is liable to be excessively loosened at the knees or the like.

The bowing restraining belt should also have the following design principles and purposes:

(1) when the user bends down to reach a certain angle, the device plays a role in assisting the ligament of the back to balance the upper body and reduces the ligament force.

(2) In addition to the restriction of the bending down, the body should be free and smooth without interfering with other body movements of the human body, such as walking, kneeling, etc.

(3) The bent waistband should be convenient for dress, and workman oneself can finish in very short time, and light in weight can not have too big physical demands to the wearer.

(4) The belt has the function of adjusting the size according to users with different statures and body types, so that each user can adjust the length of the belt randomly according to the specific situation of the user.

(5) The waist-bending limit belt needs to pay attention to the use of materials, the part in contact with a human body needs to be soft and elastic, and the part with concentrated stress needs to pay attention to the strength of the part.

Therefore, the waist bending limit belt is needed to be designed, has a simpler structure and is comfortable and convenient to use, and is more suitable for relieving the fatigue and the damage of the working waist of a worker in a bending state.
