Abstract
Abstract A retracting auditorium chair is provided with a slidably and rotatably mounted seat which has a roller engaging a cross tube connecting the chair standards so that the roller rides upon the upper portion of the tube as the seat is lowered and engages the rear of the tube as the seat is raised. Connecting means between the seat and back cause the back to move to a vertical position as the seat is raised, and roller and track means supported by the standard guide the back in this movement.
