Abstract

PURPOSE:To make it possible that the operator in the main seat uses the cord of the sub-seat besides the cord of its own seat, by providing a switching circuit between the cord circuit in the sub-seat side and the operator circuit and by connecting the cord circuit in the sub-seat side to the operator circuit in the main seat side when the operator of the sub-seat is absent. CONSTITUTION:Cord circuit 10 of the main seat is connected to opeator circuit 20 of the main seat, and cord circuit 11 of the sub-seat is connected to operator circuit 21 of the sub-seat. Switching circuit 31 is provided between cord circuit 11 of the sub-seat and operator circuit 21 of the sub-seat, and the service line and the information line from cord circuit 11 are connected to operator circuit 20 of the main seat when the operator of the sub-seat is absent.
