Abstract
A mechanism for vertical adjustability and securement of a backrest of a chair on the upright support of the chair having a housing which includes first and second housing members, and a pair of link assemblies, pivotally connected and movable between a locked position and an unlocked position. A resilient sleeve is carried by one of the link assemblies and is engageable against the upright support when the link assemblies are in the locked position to grip the upright support between the sleeve and a rod to prohibit vertical movement of the housing with respect to the upright support.
