Lumbar supporter
View Patent ↗A lumbar fixed belt that mainly holds a lumbar and a pelvic fixed belt that mainly holds the pelvis are integrally provided, and the pelvic fixed belt is inclined to the lumbar fixed belt 2 at 20° to 30° toward a lumboabdominal region, correspondingly to a physiological pelvic angle of inclination θ.
1. A lumbar supporter comprising:
a lumbar fixed belt constituted by a band, at least a part of which is stretchable, and fitted from a lumbodorsal region toward a lumboabdominal region of a human body; and
a pelvic fixed belt having a center portion overlapping with a center portion of the lumbar fixed belt and sewn together thereat, an upper edge and a lower edge, the upper edge of the pelvic fixed belt being configured to continuously overlap the lumbar fixed belt, the pelvic fixed belt being fitted substantially in parallel along a pelvic angle of inclination of the human body from the lumbodorsal region toward the lumboabdominal region so that the lower edge of the pelvic fixed belt extends below the lumbar fixed belt in a non-overlap relationship with the lumbar fixed belt.
2. The lumbar supporter according to claim 1 , wherein an angle of inclination of said pelvic fixed belt is set to 20° to 30° forward toward said lumboabdominal region with respect to a trunk axis as a base axis.
3. The lumbar supporter according to claim 1 , wherein said lumbar fixed belt and said pelvic fixed belt are overlapped and sewn together at substantial centers thereof.
4. The lumbar supporter according to claims 1 , wherein said lumbar fixed belt has a reinforcing plate placed along said lumbodorsal region.
5. The lumbar supporter according to claim 3 , wherein the upper edge of the pelvic fixed belt has portions which are inclined at a predetermined angle with respect to the lower edge.
6. The lumbar supporter according to claim 5 , wherein the predetermined angle is about 20° to 30°.
7. The lumbar supporter according to claim 5 , wherein the lower edge is essentially straight.
8. The lumbar supporter according to claim 5 , wherein said lumbar fixed belt has an upper edge extending substantially linearly.
9. The lumbar supporter according to claim 8 , wherein said lumbar fixed belt includes a back support portion with a generally rectangular shape, and belt portions extending laterally outwardly from the back support portion and having a width less than that of the back support portion.
