<p>A row construction for a telescoping seating system includes a rear riser beam (25) having a continuous horizontal slot (36) receiving and encapsulating the rear edge of the footrest panel (26) and a nose beam (27) having a similar slot encapsulating the front edge (26b) of the footrest panel (26). The nose beam (27) is then secured to support members (28, 29) which are mounted to the rear riser (25) such that assembly of these members (28, 29) forces the footrest panel (26) under compression into the opposing slots (36) on the front and rear structural beams. Thus, the footrest panel (26), the front and rear structural beams (25, 27) and the support members (28, 29) form a horizontal truss. The truss construction is extended to corresponding rows of laterally adjacent sections (50,51,52) by extending the footrest panel to bridge the joint between these adjacent sections (50, 51). Thus, the corresponding rows (10, 11) for a number of laterally adjacent telescoping sections are constructed to form a long continuous truss which extends the complete length of the adjacent rows and moves as a unit between the extended and retracted positions.</p> |
