Abstract
Abstract A back support device for supporting a wearer's back during various activities is described. The back support device includes an inner belt, and outer substantially inelastic belt, and a semi-rigid abdominal plate positioned beneath the outer substantially inelastic belt. The back support device is designed to be positioned circumferentially about a wearer's waist or lower torso region, such that the abdominal plate overlies an abdominal region of the wearer, with the substantially inelastic belt securing the abdominal plate firmly in position thereon, in order to increase the intraabdominal pressure and thereby support the wearer's lower spine. The inner belt is desirably substantially elastic in order that it closely conforms to the wearer's body and assists in increasing the intraabdominal pressure. The back support device also desirably includes a lumbosacral pad, which can be positioned within a pocket located on a rear portion of the back support device, to thereby correspond with the wearer's lower spinal region and to provide effective contact between the inelastic belt of the device and the spine due to the spine's natural curvature in the lumbar region.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
141 words
A back support device comprising: an elongate elastic inner belt including a first fastener means for securing the belt about a waist of a wearer; an elongate substantially inelastic outer belt secured to said inner belt in a substantially overlying relationship thereto; a semi-rigid abdominal plate positioned beneath said substantially inelastic outer belt; and a second fastener means for securing said outer substantially inelastic belt circumferentially about a waist of a wearer in a substantially continuous overlying relationship with respect to the circumferential direction of said abdominal plate such that said inelastic outer belt biases the abdominal plate against an abdominal region of a wearer and said abdominal plate distributes pressure applied by the outer substantially inelastic belt to underlying regions of a wearer's body to thereby increase intraabdominal pressure and providing concerted support for the lumbar region of the spine.
