A key cylinder device includes a rotor resiliently mounting tumblers that are aligned by insertion of a mechanical key, a rotor case rotatably housing the rotor that is inserted in a direction opposite to an insertion direction of the mechanical key, and a cylindrical sleeve arranged around an outer peripheral surface of the rotor and fixed to an inner surface of the rotor case. The sleeve includes a hole that allows the tumblers to be disengaged when the mechanical key is inserted and to be engaged when the mechanical key is extracted.

A device and method for the protection of a computer used to regulate the performance of a vehicle is presented. The device is a two-piece unit configured to surround the computer. The device includes a base member and a lid member. The base member is configured to releasably couple to a wall of the engine compartment. The base member has a plurality of walls therein defining an internal volume for locating the computer. The lid member is in selective communication with the base member and is configured to cover an opening of the base member and one other surface. The lid member is secured to the base member.

A key cylinder device includes a cylindrical rotor case, a rotor rotatably enclosed in the rotor case, a sleeve fixedly disposed between the rotor and the rotor case, and a tumbler moving in a radial direction inside the rotor by insertion and extraction of a mechanical key into and from the rotor. The sleeve includes a hole not engaged with the tumbler by the insertion of the mechanical key and engaged by the extraction of the mechanical key, and a dividing wall formed at a middle of the hole, the dividing wall receiving the tumbler. A part of the dividing wall is engaged with a recessed groove formed on an inner peripheral surface of the rotor case.

This invention relates to a door latch system. The door latch system includes: a housing; a latch pivotally and rotatably installed in the housing; a main locking member slidingly installed in the housing for locking the latch; a sub-locking member slidingly installed in the housing and disposed in one side of the main locking member; a hook pivotally and movably installed in any one of the main locking member and the sub-locking member; a stopping threshold formed in the other one (wherein the hook is not installed) of the main locking member and the sub-locking member; and a locking plate slidingly installed in the housing for pivotally moving the hook, wherein the main locking member and the sub-locking member are sliding together when the hook is held by the stopping threshold by the sliding of the locking plate, and only the sub-locking member is sliding when the hook is separated from the stopping threshold by the sliding of the locking plate, so that even if the door lever is being pulled when the door is being locked, the unnecessary force is not transferred to the other components such as a latch, a main locking member, and the like.

A vehicle door lock apparatus (1) includes latch and actuating housings (9, 7) that are fixed between outer and inner panels (3, 4) of a vehicle door (2). A connector fitting section (80C) is exposed through an open window (4H) in the inner panel (4) toward a vehicle interior side of the inner panel (4). A movable member (50) includes a second end (52) that projects out of the actuating housing (7), passes through an opening (80H) in the actuating housing (7) and also passes through the open window (4H) toward the vehicle interior side, where it is coupled to a link member (C3). The connector fitting section (80C) and the opening (80H) are covered by a single umbrella-shaped blocking member (89) that contacts the actuating housing (7) and the inner panel (4) around at least an upper side of the peripheral edge of the open window (4H).

A steering lock device includes a trigger that is displaced as a frame cover drops from a frame, an auxiliary lock device that holds a lock member in a locked position as the trigger is displaced under condition that the lock member is positioned in the locked position, a housed component that is arranged in a housing chamber defined by the frame cover and the frame or in a guide hole, and a trigger coupling member that couples the housed component and the trigger. When the housed component is displaced, the trigger is displaced via the trigger coupling member.

A closing system for a door or hatch of a motor vehicle includes: a bearing piece and a cylinder lock situated on the bearing piece, the cylinder lock having a cylinder bushing and a cylinder core; and a locking clamp which is held on the bearing piece, engages the cylinder bushing from behind and has a holding lug which is oriented parallel to the cylinder bushing, a fastening screw passing through the holding lug, and the tip of the screw lying in a receiving depression in the cylinder bushing in order to preload the locking clamp against the cylinder bushing. A protective element rests on an outer side of the bearing piece and has at least one retaining lug which is oriented parallel to the cylinder bushing, and the fastening screw also passes through the retaining lug.
