Abstract: A vehicle door opening/closing hinge device comprises an outer link having one end connected to a first pillar pin and the other end connected to a first door pin, an inner link disposed longitudinally apart from the outer link and having one end connected to a second pillar pin, and a connecting link having one end connected to the other end of the inner link and the other end connected to a second door pin, so as to form a five joint link mechanism. The inner link is formed with a guide member having a slot engageable with a third door pin to control door opening positions.

Abstract: A door locking apparatus which includes a striker member fixed to a vehicle body; a latch member rotatably supported in a main body of a door and engageable with the striker member; a pawl member urged in the direction of the latch member so as to engage with the latch member and limit the rotation of the latch member, wherein the pawl member is provided with an engaging groove at a contacting portion with the latch member; and a shock absorbing member fixedly inserted into the groove.

Abstract: An improved door lock mechanism having an opener plate which can pivot to move a detent to a locking or unlocking position, the detent being able to open or close the door latch. The opener plate is further movable to an activating or non-activating position by a first locking lever connected to a garnish button for movement against a turn-over snap action spring and a second locking lever covering the first locking lever and connected to a key cylinder for movement with the cylinder without lost motion.

Abstract: A door latch device includes a cancel lever pivoted to an intermediate lever in its initial position to be engaged with a pawl lever upon engagement of a pawl and latch mechanism so as to move the intermediate lever from the locked position to the unlocked position, a stopper element to rotate the cancel lever by engagement therewith upon sliding movement of the intermediate lever relative to the locking lever caused by operating the release lever when the door is open and the locking lever is in its locked position so as to disable engagement of the cancel lever with the pawl lever, and a snap action spring interconnected between the cancel lever and the intermediate lever for holding the cancel lever in either the initial position upon engagement of the pawl and latch mechanism or the rotated position thereof after engagement of the cancel lever with the stopper.

Abstract: An outside door handle assembly for actuating a door latch mechanism of vehicle doors, comprising a base member secured to the vehicle door, lever means pivotally mounted upon the base member and operably connected to the door latch mechanism, a manually operable handle member pivotally mounted upon the lever means, and locking means normally locking the handle member to the base member, characterized in that the handle assembly is rotated in a door opening direction only when the handle member is initially operated, so that an undesired door opening, such as, for example, due to the force of inertia from an automobile collision at the door location, can be prevented.
