Abstract
Abstract A single preset latch adapted to be concealed entirely within a vehicle door. The latch includes a pivoted pawl, contactor and locking lever disposed in closely spaced side-by-side relation and mounted to turn about axes which parallel the pivot axis of a turnable latching. The latch is of the ''''hard button'''' type in that the contactor is physically blocked against movement when the latch is in a locked condition.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
236 words
In a latch for a vehicle door, the combination of, a support adapted to be housed entirely within the door and comprising front and rear horizontally spaced upright plates, a latching element journaled on said support between said plates to turn between latched and unlatched positions about a horizontal axis extending transversely of the plates, a pawl disposed between said plates above said latching element and journaled to turn about a second axis spaced vertically from and paralleling said one axis between a holding position preventing turning of said latching element to said unlatched position and a release position permitting turning of the latching element, an actuator adapted to be operated manually from a side of the door and journaled on said support between said plates and in side-by-side relation with said pawl to turn about said second axis between normal and operated positions, said actuator being operable when turned to said operated position to engage said pawl to force the latter to said release position, a locking lever journaled on said support between said plates and in side-by-side relation with said pawl and said actuator to turn between locked and unlocked positions about an axis paralleling said first and second axes, and means on said locking lever directly and physically engageable with said actuator when said locking lever is in said locked position and operable to prevent movement of the actuator to said operated position.

Claim 3
Dependent Claim
54 words
A latch as defined in claim 1 in which said pawl and said actuator leave said locking lever free for shifting to said locked position when said latching element is in said unlatched position and in which said locking lever remains in said locked position as said latching element turns to said latched position.
Claim 4
Dependent Claim
113 words
A latch as defined in claim 1 in which said latching element is formed with a recess adapted to receive a striker on the vehicle to latch tHe door closed when said latching element is in said latched position, and further including a pair of inner and outer flanges formed integrally with and extending from one of said plates to the other of said plates whereby said latching element, said pawl, said actuator and said locking lever are encased by said plates and flanges, and recesses formed in said rear plate and said inner flange to expose the recess in said latching element and thus enable the latter recess to receive said striker.
Claim 5
Dependent Claim
60 words
A latch as defined in claim 1 in which the upper edge of said latching element is formed with ratchet teeth, said pawl including a tooth engageable with the teeth on said latching element, said pawl being located above said first axis to be placed in compression when said pawl tooth is in engagement with either of said ratchet teeth.
