Abstract
Disclosed is a method of placing a magnetic wire such as a magnetic heating wire into a molded vehicle seat, wherein the heating element is kept closely adjacent to the inner surface of the outer seat material of the seat during the molding process through the use of magnets in the mold. In many embodiments, the outer seat material is vinyl and the magnetic wire is an iron/chromium wire.
Claims16
A method of making a molded seat comprising:
- placing an outer seat material into a mold wherein the mold has at least one magnet;
- positioning a heating element on an inner surface of the outer seat material in the mold wherein the heating element has at least one magnetic wire component;
- and
- filling the mold with an inner seat material;
- wherein the heating element comprises a carrier and an electric wire connected to the carrier, further wherein the carrier comprises two spaced planar surfaces with a reticulated open cell structure between the two spaced planar surfaces, wherein the open cells are capable of being filled with the inner seat material.

A heated seat comprising:
- an outer seat material;
- an inner seat material within the outer seat material;
- and
- a heating element positioned within the inner seat material, wherein the heating element comprises at least one magnetic wire and a carrier, wherein the carrier comprises two spaced planar surfaces with a reticulated open cell structure between the two spaced planar surfaces, wherein the open cells are capable of being filled with the inner seat material and further wherein the at least one magnetic wire is connected to the carrier in a zig-zag pattern onto at least one surface of the carrier.
1 more element
A heated seat assembly comprising:
- an outer seat material;
- an inner seat material disposed within the outer seat material;
- a heating element comprising a carrier and at least one magnetic wire component connected to the carrier, wherein the carrier comprises two spaced planar surfaces with a reticulated open cell structure between the two spaced planar surfaces, wherein the open cells are at least partially filled with the inner seat material;
- and
- wherein the heated seat assembly is formed by a molding process in which a mold having at least one magnet magnetically attracts and retains the at least one magnetic wire component of the heating element against an inner surface of the outer seat material while the inner seat material is introduced into the mold.
