Abstract: A heating member for a vehicle exhaust gas purification device comprises an electrically conductive peripheral frame having an inner edge, a central support arranged substantially at a geometric centre of the inner edge, and a perforated heating grid formed of a plurality of elongate heating elements each having first and second ends opposite one another. The first end is linked to the electrically conductive peripheral frame and the second end is linked to the central support. Each elongate heating element occupies a respective angular sector of the perforated heating grid, and is arranged in zigzag manner within that angular sector so as to form a succession of strands connected by nodes and being linked by the nodes to the elongate heating elements occupying neighbouring angular sectors.

Abstract: A heating element for a vehicle exhaust gas purification device is provided and is to be disposed in an exhaust gas duct. The heating element extends around a central axis. and comprises a central support defined around the central axis, a heating grid extending radially around the central support, and a liaison element. The liaison element comprises a plurality of mounting brackets comprising at least a first part connecting the mounting brackets to the heating grid, at least a second part connecting the bracket to the duct, intended to be directly or indirectly attached to the duct, and at least one intermediate section connecting the first connecting part to the second connecting part. The connecting element is at least partially radially flexible.
