It is one object of the invention to provide a system which overcomes these disadvantages. Accordingly the invention as defined above includes an inside door handle operatively connected to the latch mechanism and is characterised by further electrically operable drive means for engaging and disengaging the innermost handle from the latch mechanism.
Preferably the apparatus includes first electrical switch means operable from the outside of the door, whereby a user can render the inside and the outside door handles operative and inoperative, and further electrical switch means locatable in the vehicle whereby the outside handle and/or the inside handle can be rendered operative ana inoperative. Most preferably the further electrical switch means are arranged whereby the outside handle can be rendered operative and inoperative while the inside handle remains operative. The locking system can be arranged so that the locking systems on all the doors can be actuated simultaneously by the first and further electrical switch means.
In a preferred aspect of the invention there is provided, for each door of the vehicle, apparatus comprising a pair of links, one connected to the outside handle of the door and one to a .. ., .. ~:, ' ~:'~."'`,.' ~'',: ,~'.' `,',.

Preferably one or both sets of links comprise elongate bar-like members arranged side-by~-side and each displaceable in the direction of: their length, holes extending transversely across each member, the connecting member comprising a pin which in the disengaged oondition is arranged to be withdrawn from one or both of the holes, whereby the bar members are free for relative movement, and in the engaged~condition is arranged to engage both of the holes whereby both of the members move together.

Referring to Figures 2 and 5, a latching mechanism for the door 44 of a motor vehicle includes a door latch cam 1 with its ~ -làtching~pawl 2. The latching pawl is operated both by way of a ~... ;.:.

and, when the openings are aligned, a pin 40 can be introduced into the openings to connect the two slides together. When that occurs, operation of the lever 35 is transmitted to the slide 38 which brings about operation of the latching pawl 2 of the latching mechanism. However, when the pin 40 is removed from the openings, relative movement can take place between slides 37, 38 and, in this way, the handle on the outside of the door is inoperative because movement of the handle transmitted to the lever 35 is not transmitted to the pawl via the slide 38. The pin 40 is carried on a slidable elongate rack 41 which is engaged by a pinion 42 on the spindle of motor 23. Operation of the motor drives the rack in the direction of its length to introduce the pin into the openings in the slides 37, 38 or to withdraw the pin from the openings in the slides 37, 38. The head 100 of the pin 40 is received within an enclosed slot 101 at one end of the rack 42. ~he slot 101 is open at one side so that when the pin 41 ls engaged with both openings, as shown in Figure 3, operation of the~lever 35 will cause slides 37 and 38 to move together in the direotion of the arrow and thus the head 100 of the pin moves out of the slot 101 in the direction of the arrow along a track 102. The pinl will returln to the slot under the bias of springs associated with the latch assembly (not sho-n).

Openings are provided in these slides and a pin 48 can be introduced into the openings to connect the slides together. ~he pin 48 is mounted on an elongate rack 49 which is engaged by a pinion 50 on the spindle of an electric drive motor 28. ~y actuation of the motor, the pin 48 can be introduced into, or withdrawn from, the openings in the slides 46, 47 to connect or to disconnect the lever 36 from the slide 47.

Member 16 of the switch which is within the vehicle is connected through a diode 29 to the motor 23 and its capacitor only.
Connection of member 10 to contact 11 drives the motors from the battery to the positions where the pins 40, 48 are withdrawn from the slides and the handles are disconnected from the latching mechani~ms. Connection of member 16 to contact 17 drives motor 2~. ~he connection of the motors to the battery 15 stores charge in the capacitors. Connection of the members 10, 16 to contacts 12, 18, respectively, cause the capacitors to be discharged through the motors to drive them in the opposite direction to introduce the pins into the holes in order to connect the respective slides together. Because the door is unlocked by the discharge of a capacitor, the mechanism requires no power from the vehicle battery for unIocking, so that if electrical connection is broken, e.g in an accldent, the doors may still be ; :~-.
opened.

The apparatus according to the invention is suitable for use both with a direct action latch, where one or both of the handles operates the latch directly, or with an indirect type where the handles are connected by rods or cables to the latch.
