Abstract:
1. A lumbar support, comprising: a first member arranged as a belt segment and defining first and second ends, the first member being elongate and flexible; a second member arranged as a belt segment and defining first and second ends, the first ends of the first and second members being spaced apart by a variable distance, the second member being elongate and flexible; a closure device spanning the variable distance, the closure device including a plurality of pulleys located on opposed sides of the first ends of the first and second members; at least one tension element connecting the first and second members, a first end portion of the at least one tension element connecting to the plurality of pulleys; a tensioning mechanism mounted on the first member and coupled to a second end portion of the at least one tension element, the tensioning mechanism including a housing and a retractable and extendable line arranged to be extended from the housing and automatically retract to the housing upon release of the line to permit one-way incremental winding of the at least one tension element to thereby draw the first and second members closer to one another by reducing said variable distance as the first end portion of the at least one tension element runs through the plurality of pulleys.
