ABSTRACT:
An adjustable human back and lumbar support for use with a chair having an upwardly extending back and a defined seat. The support includes a strip of flexible sheet material with a pocket for mounting an upper end of the strip at an upper part of the chair back to hold the strip against downward movement and webbing secured lengthwise of the strip to inhibit elongation of the strip. The strip is of a length to extend along and over the seat of the chair but so arranged that a back part of the strip is spaced forwardly, clear of the back of the chair along its length from the pocket to the seat portion. The back of a person sitting on the support is supported by the strip between the seat and the upper part of the back, rather than by the chair back itself, from which the strip is spaced. Hips and lower back of the sitter are urged to roll forwardly.
