Abstract
The invention relates to a heating element (20), in particular for heating user contact surfaces of a passenger compartment of a vehicle, comprising at least one heating area (100) wherein at least one electric conductor strand (1), which is used to heat, is arranged, at least one additional conductor strand (2) which is used to feed electric energy into at least one conductor strand (1) which is used to heat the heating area (100), at least one contact area (200) wherein the conductor strand (2), which is used to feed electric energy, is connected in an electrically conductive manner to the at least one conductor strand (1) which is used to heat the heating area (100). According to the invention, at least one additional conductor (3) which forms at least one part of an electrically bridging line which bridges the failure point on a failure point during local failures of at least one of the conductor strands (1, 2), is provided.
