Definition & Bedeutung von "[take] a back seat"

What is the origin of the idiom "take a back seat" and when to use it?

The idiom "take a back seat" is thought to have originated in the mid-19th century from stagecoach travel, in reference to the seats in a stagecoach. The most desirable seats were the ones in the front, which allowed passengers to see the road ahead and have a better view of the scenery. The seats in the back were less desirable, as passengers had to endure a bumpy ride and were unable to see as well. Over time, the idiom came to be used figuratively to mean to be placed in a less important or weaker position compared to someone else.
