Description

  The present invention relates to a lumbar supporter that covers at least the upper anterior iliac spine and is worn on the lumbar region to maintain the stability of the pelvis.

  Lumbar supporters are usually used to protect the lower back and stabilize the pelvis. Conventional lumbar supporters consist of a single band-shaped body that wraps around the lumbar region, and an auxiliary band that assists the supporter body is added to the outside of the supporter body to further improve the fixing force. Things can be seen. For example, Patent Document 1 describes a supporter body made of a stretchable material and a waist supporter having an auxiliary belt that is made of a stretchable material stronger than the supporter body and fixed to the supporter body. Yes.

The waist supporter of Example 1 has a pair of rounded constricted portions formed between the central portion and both end portions in the longitudinal direction, and the lower edges of both end portions are arc-shaped. , The constricted part is now along the groin part, the folding, bending and wrinkle of the fabric that constitutes the supporter body at the time of deep flexion of the hip joint is reduced, and the entire supporter body is no longer pushed upward, so the displacement is small Presumed to be.

  Further, 68 male and female subjects (34 males and 34 females aged 50 to 79) wear the waist supporter of Example 1 so that it is difficult to shift, easy to wear, and easy to move the waist. The sensory values were obtained by using a 6-step SD method, with the case of being very good and 6 being very good and 1 being very bad. Table 2 below shows the average values of 68 subjects.

  As can be seen from the results in Table 2, when the lumbar supporter of Example 1 was worn, all of the difficulty in displacement, the ease of attachment, and the ease of movement were good.
