ABSTRACT:
A telescopic seating system generally includes an innermost lower riser assembly and successive outer elevated riser assemblies. Each elevated riser assembly includes a dual deck surface and a telescopic leg assembly. Each elevated riser assembly supports a toothed belt drive system which provides the interface between each adjacent elevated riser assembly and the motive force to extend and retract the riser system. In operation, electric motors of the toothed belt drive system on each elevated riser assembly are driven by a controller to extend and retract the telescopic seating system between a fully extended position, a half-deployed position and a storage position. The half-deployed position utilizes the dual deck surface to provide half the seating capacity of each riser at twice the rise between each seating row to thereby accommodate particular venues.
