Weilen unter den Rinnen was ruled by Austria from 1381 to 1805, when it was ceded in the process of German mediatization to the Kingdom of Württemberg. Weilen was assigned by Stuttgart to Oberamt Spaichingen [de], with which it remained until that district's dissolution in 1938. Following that, Weilen was assigned to Landkreis Balingen [de]. After World War II, Weilen developed into a commuter town, beginning in the 1950s with new residential space at the town's northern and southwestern extremities. In the 1973 Baden-Württemberg district reform [de], the district of Balingen was merged with others into a new district, Zollernalbkreis. Weilen continued to grow through the 1980s and 1990s.[3]
Weilen's coat of arms shows a field of red crossed by a white bar containing, in red, the letters "V" and "R", separated by a six-pointed star. The pattern is taken from the seal of the local Schultheiß, itself drawn from the Austrian blazon. The tincture is also a reference to Austria, and the letters "V" and "R" to the name, rendered in an old spelling as "W" and "R". A municipal flag was issued on 4 July 1983.[3]
