Abstract:
1. A device for operating a door latch in a vehicle, comprising: an inside handle provided on a door inside a vehicle and having an arm; an outside handle provided on the door outside the vehicle; a fully-closing door latch provided on the door to engage with a striker of a vehicle body to hold the door closed; an operational unit provided in the door, the operational unit comprising a first base member fixed to the door, an inside input lever having an engagement hole at a lower part and coupled to the inside handle by engaging the arm of the inside handle in the engagement hole of the inside input lever, an outside input lever connected to the outside handle, and a fully-closing output lever pivotally mounted to the first base member to rotate with the inside input lever and the outside input lever and enabling an action of the inside handle or the outside handle to be tapped off; a first action-transmitting member comprising a Bowden cable and coupled to the fully-closing output lever of the operational unit at one end to move with releasing action of the operational unit; a second action-transmitting member comprising a Bowden cable and coupled to the fully-closing door latch; a locking-unlocking unit spaced from the operational unit in the door, the locking-unlocking unit comprising a second base member fixed to the door, a locking-input member pivotally mounted to the second base member and coupled to the first action-transmitting member, a locking-unlocking output lever coupled to the fully-closing door latch via the second action-transmitting member, a locking-unlocking lever pivotally mounted to the second base member and moving between the unlocking position where rotation of the locking-unlocking-input member is capable of being transmitted to the locking-unlocking output lever and a locking position where the rotation is not capable of being transmitted, and an electric actuator that moves the locking-unlocking lever to the unlocking position and the locking position, the locking-unlocking unit being connected to the operational unit via the first action-transmitting member and to the fully-closing door latch via the second action-transmitting member, the locking-unlocking unit being capable of being switched between an unlocking state in which an action with the inside handle or the outside handle is transmitted to the fully-closing door latch via the second action-transmitting member and a locking state in which the action is not transmitted, wherein the fully-closing door latch, the operational unit and the locking-unlocking unit are separated from each other; and another action-transmitting member that comprises a Bowden cable and connects the operational unit to the locking-unlocking unit to transmit locking/unlocking action from the operational unit to the locking-unlocking unit.
