Abstract
Apparatus for adjusting a back support of a chair which includes a bracket through which the back support slides. A position stop of flexible sheet material is mounted adjacent to the back support. A stop member is included on the back support, while the position stop includes apertures therein. The stop member is engaged in one of the apertures to lock the back support in position. To move the back support, the position stop is flexed to a disengaged position in which the stop member is free from the apertures. After being moved, the position stop is allowed to return to the engaged position in which the stop member is engaged within another aperture.
