Abstract
Abstract An accessory floor mat designed to overlie and protect a portion of the original carpeted floor of an automobile is preformed into a tray-like configuration which also conforms to the contours of the floor portion. The mat snugly fits into the carpeted floor well on a side of the vehicle and thereby resists mat sliding. The rigidity of the mat is such that it maintains its original position in the vehicle and also retains its shape when removed for cleaning. Raised borders of the mat terminate in rolled edges which eliminate the need for surging or otherwise finishing these edges. Optionally the mat can be provided with a recessed heel pad. The composite carpet structure from which the mat is molded preferably includes a layer of carpet fibers tufted into a primary backing material which is bonded to a sheet of open-celled foam by an extruded thermoformable copolymer of polyethylene and ethylene vinyl acetate.
