Abstract
A vehicle door latch has a selectively activated security lock that prevents a vehicle door from being unlatched by an inside door handle. The security lock is activated and deactivated when the vehicle door is open by inserting a key or other probe-like instrument into a slot in an inner panel of the vehicle door to manipulate a moveable arm of the security lock.
Claims8
An automotive vehicle door latch having a security lock comprising;
- a frame rotatably mounting an unlatching lever for rotation from a rest position to an unlatch position where the unlatching lever has a potential for unlatching the door latch, and
- an inside operating lever rotatably mounted on the frame for rotation from a rest position to an unlatch position where the unlatching lever has a potential for positioning the unlatching lever in its unlatch position,
- the inside operating lever consisting essentially of a rotor that is rotatably mounted on the frame and an arm disposed between the rotor and the frame and is slideably mounted in tracks provided on the rotor so that is has a bypass position where it bypasses the unlatching lever when the inside operating lever is rotated from its rest position to its unlatch position and so that it has an engage position where it positions the unlatching lever in its unlatch position when the inside operating lever is rotated from its rest position to its unlatch position.
An automotive vehicle door latch having a security lock comprising;
- a frame rotatably mounting an unlatching lever for rotation about a first axis from a rest position to an unlatch position where the unlatching lever has a potential for unlatching the door latch, and
- an inside operating lever rotatably mounted on a flange of the frame for rotation about a second axis that is perpendicular to a plane containing the first axis from a rest position to an unlatch position where the unlatching lever has a potential for positioning the unlatching lever in its unlatch position,
- the inside operating lever consisting essentially of a rotor that is rotatably mounted on the frame and an arm that is slideably mounted on the rotor so that is has a retracted position where it bypasses the unlatching lever when the inside operating lever is rotated from its rest position to its unlatch position and so that it has an extended position where it positions the unlatching lever in its unlatch position when the inside operating lever is rotated from its rest position to its unlatch position.
