Patent ID: 7236135

Claim:
A reinforcement piece ( 6 ) for reinforcing a piece of motor vehicle bodywork, the reinforcement piece comprising at least one strip ( 8 , 12 ) of thermoplastic material, and being characterized in that it is covered at least in part by an electrically-conductive covering ( 14 ) in such a manner that there exist at least one projection direction (D) and one projection plane (P) such that: projecting the covering ( 14 ) onto the projection plane in said direction defines a first zone ( 16 ); the projection of the piece ( 6 ) defines a second zone ( 18 ); the first zone ( 16 ) and its complement ( 19 ) in the second zone ( 18 ) are separated by a boundary ( 20 ) that intercepts the projection of at least one strip of material ( 12 ); and the boundary ( 20 ) extends substantially transversely to the intercepted projection.
