Automotive childproof safety lock control apparatus

An automotive childproof safety lock control apparatus, comprising:

• a first childproof safety lock unit configured to assume an unlocking state and a locking state and configured to transmit a door opening control force applied by an inner handle provided inside a vehicle, only in the unlocking state;
• a second childproof safety lock unit configured to assume an unlocking state and a locking state and configured to input thereinto the door opening control force transmitted from the first childproof lock unit and to transmit the door opening control force which it has inputted thereinto, only in the unlocking state;
• a door latch configured to hold a door in a closed position and configured to receive the transmitted door opening control force from the second childproof safety unit;
• a drive unit configured to perform an unlocking drive and a locking drive to displace either the first or second childproof safety lock unit to the unlocking state and the locking state, respectively;
• a door opening control detecting unit configured to detect a door opening control performed by the inner handle;
• a control unit configured to execute a locking drive control of the drive unit based on a vehicle running signal and an unlocking drive control of the drive unit based on detection of the door opening control by the door opening control detecting unit;
• and
• a childproof safety lock lever configured to be manually operated to displace the other of the first or second childproof safety lock unit in the respective states.

An automotive childproof safety lock control apparatus, comprising:

• a door latch configured to hold a door of a vehicle in a closed position in a latching state;
• a first childproof safety lock unit having a first childproof safety lock lever configured to manually assume an unlocking and a locking state;
• a second childproof safety lock unit having a first childproof safety lock lever configured to assume an unlocking state where releasing the door latch from the latching state is enabled by controlling an inner handle provided inside of the vehicle to open the door and a locking state where releasing the door latch from the latching state is disabled;
• and
• a drive unit which is linked to the second childproof safety lock unit and the door latch in such a manner as to electronically displace the second childproof safety lock lever from the locking state to the unlocking state and release the door latch from the latching state when activated in one direction and to electronically displace the second childproof safety lock lever from the unlocking state to the locking state when activated in the other direction.

An automotive door latch control apparatus, comprising:

• a lock unit configured to assume an unlocking state where the lock unit can transmit a door opening control force applied by a control handle provided on a door to a door latch and a locking state where the lock unit cannot transmit the door opening control force,
• wherein the door latch is configured to be released from a latching state by power of a drive unit which can be driven as the control handle is controlled to open the door at substantially the same time as the lock unit is displaced from the locking state to the unlocking state, the lock unit comprising:
• an input lever configured to input thereinto the door opening control force of the control handle;
• an output lever configured to be linked to the door latch;
• a connecting unit configured to assume a connecting position and a cutting-off position, the connecting unit being configured to transmit the door opening control force that the input lever has inputted thereinto to the output lever only in the connecting position;
• and
• a lock lever configured to be moved by power of a drive unit to an unlocking position where the connecting unit can be held in the connecting position and a locking position where the connecting unit is held in the cutting-off position, and
• wherein, when the door opening control force is inputted into the input lever in such a state that the lock lever is in the locking position and the connecting unit is in the cutting-off position, the lock lever is moved to the unlocking position against a biasing force exerted between the connecting unit and the lever by power of the drive unit with the connecting unit held in the cutting-off position, and when the door opening control force is removed, the connecting unit is moved to the connecting position by the biasing force, so that the lock unit is displaced to the unlocking state.

An automotive childproof safety lock control apparatus, comprising:

• a first childproof safety lock unit configured to assume an unlocking state and a locking state and configured to transmit a door opening control force applied by an inner handle provided inside a vehicle, only in the unlocking state;
• a second childproof safety lock unit configured to assume an unlocking state and a locking state and configured to input thereinto the door opening control force transmitted from the first childproof lock unit and to transmit the door opening control force which it has inputted thereinto, only in the unlocking state;
• and
• a door latch configured to hold a door in a closed position and configured to receive the transmitted door opening control force from the second childproof safety unit.
