- the present invention relates to school bus seats and more particularly to a joint system for attaching seat back frames to the remainder of the seat frame sub-structure.
- 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. Alternatively, customers can specify seats in different widths or heights and can demand various strength requirements.

This means that if the entire seat frame assembly is outsourced, it must be shipped in a complete condition, which does not nest or package well. Also, because the entire assembly is welded, paint must be applied after the frame assembly is complete.

Description
- 1. Technical Field
- The present invention relates to school bus seats and more particularly to a joint system for attaching seat back frames to the remainder of the seat frame sub-structure.
- 2. Description of the Problem
- 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. Alternatively, customers can specify seats in different widths or heights and can demand various strength requirements. School bus passenger seats vary in height and width resulting in different seat back performance characteristics.
- Differing customers' specifications have required substantially or entirely different component sets. The need to supply such component sets has even occurred relative to completed vehicles that have been put into service where the vehicle has been moved from one state or municipality to another, based on differing requirements of the new jurisdiction. The variability in size has contributed to varying component sets meant to meet strength standards. Multiple tubes, brackets and gussets are incorporated into welded seat assembly. Components were added to the various seat assemblies until the resulting design was compliant. Various seat widths and heights may use different hardware based on these changes. Therefore, seats have exhibited additional variation in component parts to meet the FMVSS 222 requirements.
- Representative of prior art school bus seat frame systems are those of
FIG. 2 and U.S. Pat. No. 6,886,889. The system ofFIG. 2 is characterized by a large number of parts and a need for a substantial amount of welding for assembly, which in turn limits flexibility in outsourcing. This occurs because the 1) frame assembly does not package well for shipping, 2) the welded design dictates painting after assembly and (3) it is difficult to outsource sub-assemblies because they have been entirely welded (creating problems for fit and paint matching). This means that if the entire seat frame assembly is outsourced, it must be shipped in a complete condition, which does not nest or package well. Also, because the entire assembly is welded, paint must be applied after the frame assembly is complete. - The invention provides for a seat frame built from subassemblies that attach at joints. These joints are able to accept fasteners, thereby eliminating welding operations, and allowing the subassemblies to be stocked in a painted condition. The minimum level of subdivision of the seat frame is into two sections, a seat back and a lower frame. The lower frame includes risers with receiving necks into which the seat back can be mounted. The seat back includes a partial perimeter framing tube which ends in rectangular sections which are engaged in the necks extending from the lower frame. The lower riser has the stamped section that accepts the upper seat frame square tube. Components are easily stackable and shipable, and may be shipped in a painted condition. Assembly is accomplished with conventional fasteners, and easy to use hand tools. In addition, the system lends itself to automated assembly steps.
- Additional effects, features and advantages will be apparent in the written description that follows.
- The novel features believed characteristic of the invention are set forth in the appended claims. The invention itself however, as well as a preferred mode of use, further objects and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:

Aninternal frame 28 and aback seat support 30 are nestled within the closed perimeter tube 26. Excluding therisers 22, 24, few of the components are reusable should seat specifications, such as width, or height of the seat back be changed. Any change necessitates a change in the perimeter tube 26 and aninternal frame 28 parallels portions of the perimeter tube 26, reinforcing the sides of the perimeter tube and adding a seat backbottom brace 34 and across member 32 to give theframe 20 rigidity. - Referring to

Support from the floor 42 is provided by anaisle riser 46. Support from the wall 44 is provided by awall riser 48. Aisleriser 46 andwall riser 48 differ from the aisle risers and floor risers known from the art illustrated inFIG. 2 in that they form more of the seat frame than is traditional in school bus applications. Both theaisle riser 46 and thewall riser 48 are modified to function as frame elements, in part by inclusion ofnecks 50 which provide bases of support for an open ended,partial perimeter tube 52 used to define the top and sides of a seat back portion offrame 40.
