  • Telescoping seating system with automatically folding chairs
    Patent number: 4063392
    Abstract: A seating system having a number of rows which may be extended for use or retracted for storage is provided with individual chairs. As each row is moved forwardly relative to the next higher row, the chair backs pivot to the upright or use position where they are latched. As each row is moved rearwardly relative to the next higher row, the latches holding the chair backs in the use position are released and the chair backs are engaged by the deck of the next higher row to fold the chair backs downwardly and forwardly to the closed or storage position so that they may be stored in the space between adjacent decks.
