Durable Heater for Vehicle Exhaust Gas Purifier This heater (30) for vehicle exhaust gas purifier comprises an electrically conductive peripheral frame (42) having an inner edge (46), a central support (64) disposed substantially at the geometric center (G) of the inner edge (46), and a perforated heating grid (72) formed of a plurality of elongated heating elements (74) each having first and second ends (75, 76) opposite to each other, the first end (75) being linked to the peripheral frame (42) and the second end (76) being linked to the central support (64). Each elongated heating element (74) occupies a respective angular sector (77) of the heating grid (72) and is arranged in a zigzag manner within this angular sector (77) so as to form a succession of strands (82, 83). ) connected by nodes (88) and being linked by said nodes (88) to the elongated heating elements (74) occupying the neighboring angular sectors (77).
