Chassis rail system for theater seat

Abstract

A new and improved chassis rail system for theater seating comprises a pair of rails affixed to a theater floor by means of suitable bolts inserted through holes defined within the rails. In addition, upstanding bolts, captured by means of spring-fingered washers affixed to the rails, are provided such that the bolts can project upwardly through holes defined within the legs of the theater seating unit. When nuts are secured upon the bolts, the theater seating units will be fixedly secured to each one of the rails such that the theater seating units are automatically aligned in a linear manner. In accordance with a second embodiment of the present invention, only a rear rail is employed. The rear rail has a raised lip portion running along its front edge portion such that a rearwardly extending tab of each rear leg of each theater seating unit can extend beneath the raised lip, and engage the same, thereby effectively locking the theater seating unit in place. Then only each front leg of each theater seating unit need be bolted to the theater floor.
