ABSTRACT:
A telescoping seating system has a plurality of rows adapted for movement between an extended or use position and a retracted or storage position. Each row is equipped with seating mounted on a frame which, in turn, is mounted to the rear of the deck of a row for pivoting between a raised or use position and a lowered or storage position, where the seating is positioned between the decks of adjacent rows when stored. A latch mechanism for locking the seating frame in the raised position when a row is extended includes a drive rod extending above and along a rear portion of the deck. The drive rod is spring-biased to rotate in one direction toward a locking position in which latch members carried by it engage the seating frame to lock it in place when the frame is raised. Arms connected to the drive rod extend below the deck of the row on which the seating frame is mounted and are engaged and counter-rotated to a release position when the next lower row is substantially retracted to a position almost fully nested beneath the aforementioned higher row. If any one arm is engaged and actuated, the drive rod is counter-rotated to release all of the seating for that row. Thus, the seating of a row is unlocked by the retraction motion of the next lower row and uniform seat unlocking is accomplished before the row on which the seating is mounted begins to retract.
