Blazon:„Party per fess sable and chequy gules and Argent; supporting a narrow chief Or, an armed and langued gules demi-lion issuant Or, in the right claw an iron symbol Argent.“  
The arms were officially granted on May 28, 1971. The arms are based on the arms of the Zach family, who played an important role in the village in the 15th century till 1649. To distinguish the arms from the family arms, the lion is holding the symbol of iron. This also refers to the former iron mining in the area.
