The present invention relates to school
bus seats and more particularly to a modular school bus seat frame characterized by differentiated sub-assembly possibilities to ease of installation on a bus and readily modified to meet differing configuration requirements by customers all with a minimized number of differing parts.
School
bus seats are built to meet many differing customer specifications. For example, some
bus seats must accommodate three point safety belts by providing a compatible upper back rest, other specifications call for a universal child restraint attachment equipped lower frame, while still others provide standard DOT (United States Department of Transportation) seat backs. At the same time customers can specify seats in different widths or heights and can demand various strength requirements.
Differing customers' specifications have required substantially or entirely different component sets. The need to supply such component sets has even occurred in relation to completed vehicles that have been put into service, particularly when the vehicle has been moved from one state or municipality to another due to differing requirements of the new jurisdiction.
The invention provides a modular
bus seats assembly for school busses. The seat assembly includes an aisle riser including a support neck, a wall riser including a support neck, a front cross support fitted between the aisle riser and the wall riser, a rear cross support fitted between the aisle riser and the wall riser, a perimeter tube fitted at opposite ends to the support necks of the aisle riser and the wall riser, respectively, and a back panel supported within the perimeter tube behind and above the rear cross support.
