In 1805, Ratshausen, previously a possession of the Austrian County of Hohenberg, was annexed by the Kingdom of Württemberg.

[3] The municipality (Gemeinde) of Ratshausen is located in the Zollernalb district of Baden-Württemberg, one of the 16 states of the Federal Republic of Germany.

This pattern is derived from a seal used in the 19th century by the local Schultheiß that portrayed an oval shield with a wreath and a trowel upon it.

The tool itself is a reference to the compulsory labor inhabitants of Ratshausen were expected to perform in the summer, usually the laying of bricks.

The tincture, a reference to the County of Hohenberg, was decided by the provisional post-WWII Württemberg-Hohenzollern government that awarded this coat of arms to Ratshausen on 27 March 1950.
