Abstract
A deployable telescopic seating structure employs a backstop arrangement to prevent users and operators from coming into contact with structures that may cause injury, such as interengaging metal elements that limit the extent of deployment. The backstop portions are arranged 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 an an intermediate step. The backstop arrangement has an engagement portion with a flange element that extends transversely therefrom and which engages with a top surface of the seating level. Preferably, the engagement portion forms a forwardmost edge termination. A fastening portion is arranged intermediate of the engagement portion and the riser portion of the backstop member. Structural integrity and strength of the riser portion is enhanced by forming same as a multi-wall structure having supporting cross elements therebetween. The backstop arrangement can be formed as a continuous extrusion of a polymeric material, such as vinyl.
