The term "dickey-seat" refers to an extra seat in a vehicle, typically located at the back and facing away from the driver. Other terms used to describe this type of seat include jump seat, rumble seat, and mother-in-law seat. In older model cars, this additional seat was often used to accommodate an extra passenger or for added storage space. The term "dickey-seat" is now considered outdated and rarely used in modern automobiles. However, the concept of an additional small seat or fold-down bench remains popular in certain types of vehicles, such as station wagons or minivans.
