Abstract
Abstract An automobile floor mat designed to reduce movement of the mat relative to the floor having a relatively stiff portion and a second portion having a relatively flexible portion, the stiff and second portions each having base portions of monolithic elastomeric materials connected in a hinge area so that the mat can be molded in a single molding operation. The relative difference in rigidity permits the flexible portion to bend relative to the stiff portion and can be accomplished by materials of different thickness or rigidity or both.
