Abstract
This research attempted to develop a prototype heavy- truck seat with integrated seat belts, requiring no attachment of the seat belt to the vehicle's body or tether belts attached to the floor.
The design process consisted of iterations between theoretical analysis and actual model testing. The Mechanics of Materials method was selected as the analytical tool throughout the design process. In addition, a number of physical models were built and tested at National Seating's facilities in Vonore, Tennessee, in order to supplement the theoretical analysis.
A final prototype capable of sustaining the required loads was built and tested. The test results confirmed that the belt-in-seat concept is definitely feasible from the structural standpoint alone.
The integrated belt-in-seat design concept may be offered as an alternative to the conventional seat design in the heavy-truck industry. Despite the fact that this design concept demands a heavier structure, the weight added is small relative to the overall weight of a truck. Furthermore, this minor drawback may be offset to a large degree by the added safety and comfort.
Before the belt-in-seat design concept is fully implemented, the prototype may need to be optimized in order to meet National Seating's current tooling. Additional manufacturing capabilities may be required to reduce costs in order to meet the market's needs.
