The charge on the dexter (armsbearer's right, viewer's left) side refers to the Lordship of Wartenstein, an Electoral-Trier fief to the House of Warsberg. The other charge, on the sinister (armsbearer's left, viewer's right) side, is the heraldic device once borne by the Lords of Heinzenberg, a buckle. Municipal council, on 28 January 1966, gave the architect Palm from Bad Kreuznach the task of designing a municipal coat of arms. At a council meeting on 16 May 1966, council adopted the design that had been put forth. After consent by the state archive, the Ministry of the Interior in Mainz granted approval for Heinzenberg to bear its own arms on 29 June 1966. The German blazon does not mention that the lion faces sinister (heraldic left). The municipal banner also bears this coat of arms in the centre.
