Description

The present invention is a physical load that the adherend receives when recovering from the forward bending posture and the sitting posture to the standing posture by being worn on the body and used by the adherend with the forward bending posture and the sitting posture. Related to assist suits.

Workers who work in front bend and sit in a factory, etc., workers in nursing facilities, or farm workers, etc., and the adherend with forward bend and sit returns to a standing position The following is known as an example of an auxiliary device worn and used on the body in order to reduce physical load when doing exercise.

For example, the auxiliary device described in Patent Document 1 arranges an elastic member 10 having elasticity in the bending direction independently on the back of the body so as to extend from the back to the thigh, and the upper end of the elastic member is a vest 20 The elastic member is attached to the body so as to be slidable in the longitudinal direction in the holding portion 21 provided, 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 The pad 40 is suspended from the vest-like clothes by the connecting belt 50 located on the trunk side, and when it bends forward, the load on the waist is reduced by the restoring force of the elastic member, and the upper surface of the elastic member slides and the body surface of the back of the body Since the change in distance can be absorbed and the movement can be performed without feeling of restraint, and 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 for holding 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 at the time of forward bending operates in series from the thigh to the back through the outside of the buttocks. Because it is connected and curved, it is effective for the resilience during forward bending, but it is inconvenient in use because the sitting posture itself can not be taken.

Moreover, as a waist part load reduction tool which can cancel | release or return the function which assists the muscles of the back with a simple operation to patent document 2, it is
One main member 11 disposed to the right knee through the left shoulder, back, right waist, right buttock, and right thigh back, and through the right shoulder, back, left waist, left buttock, and left thigh back And the other main member 12 disposed to the left knee, the one main member 11 and the other main member 12 intersect at the back, and the one main member 11 and the other main member 12 intersect Spaced below 13 and one of the main members 11 is displaced below the intersection 13 to the right side and the other main member 12 is displaced below the intersection 13 to the left side. Mitigation devices are disclosed.

This stress relief device is specialized in the function of assisting the muscles of the lower back, and hardly contributes to the assisting power when restoring from the forward bending or sitting position to the standing position.

In addition, Patent Document 3 is a garment that can effectively assist in maintaining the forward inclined posture of the pelvis while stretching the chest, and the back side of the underwear 1 includes the sacrum side of the gluteus maximus muscle and the sacrum concerned. A pattern PA1 is formed to cover the corresponding area so as to locate the corresponding area inside, and the lower area in the area of the front area corresponding to the area where the pattern PA1 is formed in the front area of the underwear 1 is covered A clothes having a pattern PA2 formed thereon and a pattern PB1 which generates tension on both shoulders in a direction to spread the chest when worn is formed on the back surface.

In the case of this garment, the freedom of movement is maintained only by seaming patterned elastic material on each part of the underwear, but the resilience from forward bending and sitting to standing position There is a problem that the contribution to the operation is small, and setting this to a large value makes the operation itself difficult.
