ABSTRACT:
Improved automatic seating for a telescopic system includes stancheons for mounting individual chairs. Each stancheon includes forward and rear frame members which are pivotally mounted to a bracket and arranged to pivot between a raised use position when the rows are extended and a lowered storage position when the rows are retracted for storage. A coil spring is connected between the stancheon frame members and biases them to the raised position so that the seating raises automatically when the rows are extended for use. Each stancheon is secured in the raised position by a self-tightening latching mechanism which is actuated independently of all other stancheon latches so as to compensate for tolerances in an individual stancheon assembly and to latch it securely in the use position, whereas all latches are disengaged in unison by movement of the next lower row to its storage position. The stancheon frame members cooperate not only to tension the coil spring as they are rotated to the storage position to provide a restoring force for raising the seating, but they also rotate the arm rest to become generally aligned with the stancheons as the seating is lowered to the storage position.
