<p>A vehicle floor tray (1500) with deep sides (1510-1516) is vacuum- molded from a multiple extrusion thermoplastic polymer sheet (2530) such tha t it has high shear and tensile strength, an acceptable degree of stiffness and a hig h coefficient of friction on its upper surface (1504). The floor tray design is digitally fitted to a foot well of a particular model of vehicle such that, even after a reservoir (1522) is incorporated into the design, at least ninety percent of the lower surface (1502) of the tray is no more than one-quarter of an inch (0.64 cm) from a digitally acquired model (1900) of the foot well surface, when the model is superimposed onto the design to achieve a best fit.</p> |
