Abstract: A heating member for a vehicle exhaust gas purification device includes an electrically conductive outer peripheral frame that has a geometric center and is symmetrical about an axis. An electrically conductive central support is centered on the geometric center, and a perforated heating grid is centered on the geometric center. The heating grid extends between the electrically conductive central support and the electrically conductive outer peripheral frame. The heating grid is formed of a plurality of strands connected by nodes, with the plurality of strands delimiting openings there between.

Abstract: A heater is suitable to be arranged opposite and away from an upstream or downstream face of an exhaust gas purification member of a vehicle. The heater comprises a fastening ring with an electrically conductive frame having a geometric center, a central support arranged substantially at the geometric center of the frame, and a plurality of elongate heating elements each having first and second ends opposite one another. The first end is connected to the frame and the second end is connected to the central support. The fastening ring further comprises a plurality of electrically conductive radial protrusions distributed around the frame and protruding toward the outside of the frame.
