20230130820 · 2023-04-27 ·

Disclosed herein is a method of manufacturing heating elements for vehicle interior materials, which includes forming a base part having the same shape as a curved surface of a subject, forming an electrode part on an upper surface of the base part, and stacking a heating part on upper surfaces of the base part and electrode part. Accordingly, the heating element is manufactured in advance to have the same shape as the curved surface of the subject and then adhered to the subject so that the heating element is overlapped on and pressed against the subject without deformation. Thus, it is possible to make overall temperature distribution uniform and improve product quality.

Electrothermal heater mat

In manufacturing an electrothermal heater mat, there is provided a preform which comprises a laminated stack of dielectric layers which are made of thermoplastic material and include a central layer or group of layers which include(s) reinforcement and first and second outer groups of layers which do not include reinforcement. The preform includes a heater element and the preform has a first configuration. The preform is then heated to a temperature (e.g. 180° C.) between the glass-transition temperature of the thermoplastic material and the melting point of the thermoplastic material, and the heated preform is formed into a second configuration which is different to the first configuration so as to produce the heater mat.
