Brace having elastic and inelastic portions

摘要

Braces having elastic portions that can be made effectively inelastic, based on a level of comfort or support desired by a user, via an inelastic tightening mechanism are disclosed. Some contemplated braces have lumbar supports that are at made at least in part of an elastic material, and inelastic tightening systems that extend across the elastic material and can decrease the effective elasticity of the elastic material to provide greater support.
