Abstract
An adjustable seat assembly comprises a horizontal seat. A pedestal is secured to the seat in a downwardly and forwardly inclined position and is secured to a carriage having two spaced frames extending around two elevated parallel rails. One frame has a top bar normally bearing on tops of the rails and a bottom bar spaced from the undersides of the rails. The other frame has a top bar spaced from the tops of the rails, and a bottom bar abutting the undersides of the rails and carrying a catch member which normally engages in one of a plurality of holes in the underside of the rails. When the seat is raised forwardly, the catch member disengages from the hole to permit longitudinal movement of the seat carriage along the rails.
