DOOR LOCK PREVENTING DEVICE WHEN AUTOMOBILE KEY IS FORGOT TO BE PULLED OUT

摘要

PURPOSE:To securely prevent a door lock when a key is forgot to be pulled out by providing an electrical fixed device for maintaining a door lock device in the released state in the case that the key is left in the ACC position of an ignition switch as well as a door switch is turned on. CONSTITUTION:In the case that a driver pulls a door lock knob up and opens a door with a key left in the ACC position of an ignition switch, a switch A is turned on as well as a door switch B is turned on, thereby supplying current to a fixed device C, so that a door lock device is kept in the door unlocked state. In this state, the door lock knob cannot be pushed down, thereby making a keyless door lock impossible. Meanwhile, in the case that the driver pulls the key out of the ignition switch, opens the door, gets off a vehicle and locks the door, the current isn't supplied to the fixed device C, thereby enabling a door lock knob D to be pushed down so as to make the keyless door lock possible.
