Abstract: A door lock arrangement for a vehicle in which there is no pillar against which the trailing edge of a forwardly hinged door may engage, includes locks provided at the top and bottom corners of the door and a centrally located mechanism for simultaneously operating said locks. This mechanism includes means for producing both of the so called "keyless locking" and "self cancellation" functions.

Abstract: A child proof door locking device for use with an automotive door is disclosed, which comprises a base plate securely attached to the door, an inside lever pivotally connected to the base plate and pivotally movable in response to handling of the inside handle, an outside lever pivotally connected to the base plate and pivotally movable in response to handling of the outside handle, a first device for causing the latching device to assume its inoperative condition when the outside lever is pivoted in a given direction, a second device for linking the outside lever with the inside lever so that pivoting of the inside lever in a given direction induces the pivoting of the outside lever in the given direction, and a child proof lever pivotally connected to the base plate and disengaging the second device from the inside lever when assuming its child proof position.
