Abstract
A deployable telescopic seating structure employs a backstop arrangement to prevent users and operators from coming into contact with structure that may cause injury, such as interengaging metal elements that limit the extent of deployment The backstop portions are arrangement in the aisle region of the telescopic seating structure and have an overall height that is responsive to the height of one seating level above another, or in another embodiment, to the difference between such height and an intermediate step. The backstop arrangement has an engagement portion with an edge portion that precludes a discontinuity on the walking surface of tile seating structure. Structural integrity and strength of the riser portion is enhanced by forming same as a multi-fascia structure having a reinforcing corrugation therebetween. A curved back portion along the lowermost edge serves as a termination and additionally adds strength to the backstop arrangement. The backstop arrangement can be formed by bending sheet material or as a continuous extrusion of a polymeric material, such as vinyl, which is fire retardant and which provides injury reducing resilience in the event of impact by a player.
