Abstract
A locking device for allowing horizontal seat positioning of a chair seat has a friction strip or brake pad between a seat pan and a seat plate. A screw and spring assembly is used to resiliently hold the seat pan and the seat plate together such that by lifting up on the forward portion of the seat pan, the friction strip, if attached to the seat plate, is separated from the seat pan allowing the seat pan to be moved horizontally in forwardly and rearwardly directions, thus adjusting the seat position. When the front of the seat pan is lifted substantially vertically, the screw and spring assembly is compressed to allow the seat pan to separate sufficiently from the friction strip and allow relative movement of the seat pan with respect to the seat plate. As an alternative, a lever may be used to loosen a locking mechanism and therby allow seat adjustment.
