Title (EN) TELESCOPING SEATING SYSTEMS WITH AUTOMATICALLY FOLDING CHAIRS
(FR) SYSTEME TELESCOPIQUE DE SIEGES AVEC CHAISES PLIABLES AUTOMATIQUEMENT
Abstract:
(EN) In a telescoping seating system having a number of rows (10, 11, 12) which may be moved between an extended or use position and a retracted or storage position, chairs (S, B) or other seating is mounted on stanchions (22) which are pivotally mounted to the rear of the deck (13) in each row. The stanchions are pivoted to an upright position when the system is extended for use and folded to a horizontal position when the system is retracted for storage by means of an actuator mechanism (40, 41) mounted to the forward portion of the next higher row and operative in response to relative movement between adjacent rows. In this manner, the height of the seats is independent of the rise of the system for more comfortable seating. A torsion rod assembly (50, 64, 65, 60) is mounted beneath the seating to counterbalance at least some of the weight of the seating in the storage position. Locking members (27) engage the stanchions in the use position to secure the seating in the raised position. The locking members are released in response to the closing motion between adjacent rows to permit the seating to be folded to the storage position in the space between adjacent decks.
(FR) Dans un systeme telescopique de sieges ayant plusieurs rangees (10, 11, 12) pouvant etre deplacees entre une position depliee ou d"utilisation et une position repliee ou de rangement, des chaises (S, B) ou autres sieges sont montes sur des etancons (22) montes sur pivot a l"arriere du plancher (13) de chaque rangee. Les etancons pivotent en position verticale lorsque le systeme est deplie pour son utilisation et en position horizontale lorsque le systeme est replie pour son rangement au moyen d"un mecanisme d"actionnement (40, 41) monte sur la partie avant de la rangee suivante superieure et fonctionnant en reponse au mouvement relatif entre les rangees adjacentes. De cette facon, la hauteur des sieges est independante de l"elevation du systeme pour ce qui est du confort. Un assemblage a barre de torsion (50, 64, 65, 60) est monte sous le siege pour compenser au moins une partie du poids du siege lorsqu"il est range. Les organes de verrouillage (27) s"engagent dans les etancons lorsqu"ils sont en position d"utilisation pour assurer le maintien du siege en position droite. Les organes de verrouillage sont relaches en reponse au mouvement de fermeture entre les rangees adjacentes pour permettre le repliage du siege en position de rangement dans l"espace situe entre les planchers adjacents.
