    Patent number: 9500020
    Abstract: If closing operation to the passenger's seat sub switch continues for not less than a prescribed time period Tb, a passenger's seat relay contact on a close side is turned ON. If the closing operation to the passenger's seat sub switch thereafter ends before a prescribed time period Tc elapses, the passenger's seat relay contact on the close side is kept ON. If opening operation to the passenger's seat sub switch continues for not less than the prescribed time period Tb, a passenger's seat relay contact on an open side is turned ON. If the opening operation to the passenger's seat sub switch thereafter ends before the prescribed time period Tc elapses, the passenger's seat relay contact on the open side is kept ON.
