Abstract: A lock unit for use on automobile seats and the like of the type comprising a latch engageable with a stationary striker, and a ratchet engageable with the latch for retaining the striker in a first, confined position in the lock unit. In a second position of the latch, the latch is released from the ratchet, and the striker is freed. The lock unit has a wedge member whose movement is coupled with the movement of the ratchet into and out of engagement with the latch. The wedge member is urged resiliently to engage one side of the striker while the striker is subject to the binding action by the latch on its opposite side. Accordingly, loosening, chattering and rattling of the striker are suppressed. When the ratchet is moved out of engagement with the latch, the wedge member is moved away from the latch and the striker.

Abstract: This automobile locking apparatus includes a one-piece, molded, plastic body having a pivotal door latch and associated ratchet pivotally mounted in a recess in one side thereof and a cooperating release lever and locking lever pivotally mounted, respectively, on a pair of integral sleeves which project from the opposite side of said body coaxially of the pivot axes of said latch and ratchet. A link which interconnects the release and locking levers, respectively, is engageable with a pin on the ratchet to prevent the locking lever to be swung into a locking position except which the release lever has been swung to a door-opening position.

Abstract: A power-driven automobile door locking device of the type wherein a latch engages and arrests a striker on the door. The device has a lock lever capable of assuming a locking position in which the latch is not releasable and an unlocking position in which the latch is releasable. The lock lever is moved by a motor between the locking and unlocking positions. The motor drives a rotary disk in rotation, which disk has an essentially spiral cam groove in the surface thereof. A cam follower engages with the spiral cam groove, and, as the disk is rotated, the cam follower is caused to move radially of the disk, the radial movement of the cam follower is transmitted to the lock lever through any suitable mechanism. The spiral groove operates to transmit an amplified force to the cam follower. The rotary disk may be replaced by a rotary cylinder having a cam groove in its cylindrical surface.

Abstract: A latch member or rotor is rotatably mounted in a main body or frame, attached to a vehicle door, for engaging a striker affixed to the vehicle body. Also mounted in the main body, in coplanar relation to the latch member, is a ratchet engageable with the latter to inhibit its motion in a direction to disengage the striker. The main body has an upstanding bracket on which three levers are mounted for pivotal motion about a common axis, in planes perpendicular to the plane of the latch member and the ratchet. The three levers are: (1) an actuating lever acting directly on the ratchet to cause the same to disengage the latch member and hence to unlatch the door; (2) an outside release lever linked to an outside door handle; and (3) an inside release lever linked to an inside door handle. These levers are interrelated in such a manner that the latch member releases the striker upon actuation of either the outside or the inside door handle.

Abstract: A latch device having a locking mechanism is locked and unlocked by a lock operating device comprising: a lock lever coupled to and operating the locking mechanism when driven to undergo displacement between terminal lock and unlock positions; a motor for driving the lock lever; a retaining member exerting an elastic force (1) to cause the lock lever to undergo the displacement with a click motion, over-riding an intermediate dead-center point against an elastic resistance and (2) to retain the lock lever positively in either terminal position after each displacement; and a retraction device for temporarily nullifying or greatly reducing the action of the retaining member at the time of the displacement of the lock lever.
