seat belt rule
n.— «Basketball coaches in Iowa must keep their seats in their seats because of what is known as the “seat belt rule.” Iowa boys’ coaches have had this rule for years, and it was approved for girls’ coaches this week (there are separate governing bodies for boys’ and girls’ sports in Iowa). The rule means coaches must sit during games instead of stalking the sideline like a beast on a chain.» —“Coaches, back to your seats” by John Millea Star Tribune (Minneapolis-St. Paul, Minnesota) May 24, 2007.
