Abstract
A rotary seat for a vehicle has a seat cushion member rotably supported on a support shaft vertically mounted on the vehicle floor. Driving apparatus is connected to the seat cushion member for automatically rotating the seat cushion member between a direction toward the front of the vehicle and a direction toward a side door of the vehicle when the seat cushion member is not occupied. Disconnecting equipment is included for disconnecting the driving apparatus from the seat cushion member to allow the seat cushion member to be manually rotated when the seat cushion member is occupied. Control devices are provided for controlling the driving apparatus and the disconnecting equipment to place the seat cushion member in an automatic rotating mode or a manual rotating mode depending upon whether the seat is occupied.
