This invention relates to a flat heating element in particular for heating surfaces in contact with the user in the passenger compartment of a vehicle, comprising at least one electrical conductor. According to the invention, the electrical conductivity of at least one of these electrical conductors

대표청구항 ▼

1. A heating element for heating user-contacted surfaces of a passenger compartment of a vehicle, comprising: one or more electrical conductors including at least one strap wherein an electrical conductivity of least one of the one or more one electrical conductors is irreversibly reduced by at least localized self destruction if the temperature thereof at least locally exceeds a permissible maximum temperature. 2. The he lemon according to claim 1,wherein the permissible maximum temperature is 280° C. 3. The heating element according to claim 1, wherein the one or more one electrical conductors are disposed on a conductor support, further wherein the conductor support loses its material cohesion when the permissible maximum temperature is exceeded. 4. The heating element according to claim 3, wherein the permissible maximum temperature is 280° C. 5. The heating element according to claim 3, wherein the permissible maximum temperature is 220° C. 6. The heating element according to claim 3, wherein the conductor support has a thickness between 20 nm and 0.1 μm. 7. A heating element for heating user-contacted surfaces of a passenger compartment of a vehicle, comprising: one or more electrical conductors disposed on a conductor sup ort and including at least one strand, wherein an electrical conductivity of at least one of the one or more one electrical conductors is irreversibly reduced by at least localized self destruction if the temperature thereof at least locally exceeds a permissible maximum temperature of at most 280° C. 8. The heating element according to claim 7, wherein the conductor support loses its material cohesion when the permissible maximum temperature is exceeded. 9. The heating element according to claim 7, wherein the permissible maximum temperature at most 220°C. 10. A heating element for heating user-contacted surfaces of a passenger compartment of a vehicle, comprising: one or more electrical conductors disposed on a conductor support and in at least a strand,wherein an electrical conductivity of at least one of the one or more one electrical conductors is irreversibly reduced by at least localized self destruction if the temperature thereof at least locally exceeds a permissible maximum temperature or if a heating current exceed a permissible current load; andwherein the conductor support loses its m cohesion if the temperature there of at least locally exceeds the permissible maximum temperature thereby destroying conductivity of at least one of the one or more electrical conductors. 11. The heating element according to claim 10 wherein the permissible maximum temperature is 280° C. 12. The heating element according to claim 10, wherein the permissible maximum temperature is 220° C. 13. The heating element according to claim 1, wherein a heating current is distributed to neighboring electrical conductors upon the localized self destruction. 14. The heating element according to claim 13, wherein all of the electrical conductors are irreversibly reduced by self destruction if the heating current exceeds a permissible current, load. 15. The heating element according to claim 1, wherein substantially all of the electrical conductors are irreversibly reduced by self destruction if the average temperature surrounding the heating element exceeds a permissible maximum temperature. 16. The heating element according to claim 1, wherein the at least one or more strands form at least one bundle of strands so if the at least one or more strands should fail, the electrical conductor remains functional. 17. The heating element according to claim 10, wherein the permissible maximum current load is 100 mA at an operating voltage between 10 V and 50 V. 18. The heating element according to claim 1 wherein the heating current is distributed to neighboring electrical conductors upon the localized self destruction. 19. The heating element according to claim 10, wherein the at least one or more strands form at least one bundle of strands so if the at least one or more strands should tail, the electrical conductor remains functional. 20. The heating element according to claim 10, wherein the conductor support has a thickness between 20 nm and 0.1 μm.
