Abstract
A method for manufacturing a heating mat for a motor vehicle. The method includes the following steps: providing a heating ply having a deformable structure and two heating elements inserted into the structure, said two heating elements being separated by a deformation area of the structure; stacking the heating ply between an upper layer and a lower layer, wherein at least one of the heating ply and the upper and lower layers includes a thermoformable material; assembling the stack by at least one fastening rod; and thermoforming the stack thus assembled, so as to secure the heating ply and the upper and lower layers into a single piece; and stretching the deformation area in the stacking direction.
