Description

The present invention relates to a physical load applied to an adherent when recovering from a forward-bent posture and a sitting posture to a standing posture by being used by the wearer with a forward-bent posture and a sitting posture. Assist suit to reduce

Workers who are often bent forward and sitting in factories, workers in nursing care facilities, and workers engaged in farm work, etc. As an example of an auxiliary device that is used by being worn on the body in order to reduce the physical load at the time, the following is known.

For example, in the auxiliary device described in Patent Literature 1, the elastic member 10 having elasticity in the bending direction is arranged on the back of the body independently from the back to the thigh, and the upper end of the elastic member is attached to the vest-like garment 20. The holding portion 21 provided is attached to the body so as to be slidable in the longitudinal direction, and the lower end of the elastic member is connected to the thigh belt 30 attached to the thigh, and the buttocks connected to the thigh belt 3 When the pad 40 is suspended from the vest-like garment by the connecting belt 50 located on the trunk side and bent forward, the load on the lower back is reduced by the restoring force of the elastic member, and the body surface on the back of the body is slid by sliding the upper end of the elastic member. The change in distance can be absorbed, it can operate without a sense of restraint, and since the mounting position of the elastic member is held by the connecting belt, there is no need to tighten the body in the circumferential direction to hold the mounting position

However, in this auxiliary device, since the elastic member 10 is fixed to the lower end portion of the thigh belt 30, the elastic member 10 during the forward bending operation is a series from the thigh to the back through the outside of the buttocks. Since it is connected and curved, it is effective for restoring force when bent forward, but it is inconvenient in use because it cannot take a sitting posture itself.

Further, in Patent Document 2, as a lower back burden reducing tool capable of releasing or returning the function of assisting the muscles of the lower back by a simple operation,
One main member 11 arranged over the right shoulder through the left shoulder, back, right waist, right hip, and right thigh back, and through the right shoulder, back, left waist, left hip, and left thigh back And the other main member 12 arranged over the left knee, one main member 11 and the other main member 12 intersect at the back, and one main member 11 and the other main member 12 intersect each other. Lumbar load with a compression avoidance function that is spaced below 13, one main member 11 is displaced to the right body side below intersection 13, and the other main member 12 is displaced to the left body side below intersection 13 A mitigation device is disclosed.

This burden reducing tool is specialized in the function of assisting the muscles of the back and back, and hardly contributes to the assisting force when restoring from the forward bending or sitting position to the standing position.

Patent Document 3 discloses a garment that can effectively assist in maintaining a forward tilting posture of the pelvis while stretching the chest, and the sacrum side of the gluteal muscle is placed on the sacrum on the back of the underwear 1. A pattern PA1 is formed to cover the corresponding area on the inner side, and the lower part of the front part of the underwear 1 covers the lower abdomen around the front part corresponding to the area where the pattern PA1 is formed. A pattern PA2 is formed as described above, and a garment having a pattern PB1 that generates tension on both shoulders in the direction of expanding the chest when worn is disclosed.

In the case of this garment, since the patterned elastic material is only joined to each part of the underwear, the degree of freedom of movement is maintained, but the restoring force from the forward bending and sitting to the standing position is maintained. There is a problem that the operation itself is difficult to perform.
