Abstract: A cheek link apparatus includes an arm in which a stopper portion is formed by covering a stopper core portion with a resin material and a holding member which defines a full open position of a door by being brought into abutment with the stopper portion. The stopper core portion has curved surfaces on end faces which face an abutment surface of the holding member at least when the abutment surface of the holding member is brought into abutment with the stopper portion. The stopper core position is positioned such that extensions extending in a direction in which a load is applied to the stopper core portion by the holding member pass the curved surfaces.

Abstract: A latch apparatus brings a latch which is accommodated rotationally movably in a case made up of a base plate and a cover plate into engagement with a striker which enters an entrance groove in the case. A fastening member which fastens the case to a mount member so as to move relative to the striker is provided within a range defined by projecting an area which has a radius centering at the striker onto the case, the radius being equal to a distance to an outermost position of the latch which is in engagement with the striker.

Abstract: A first and a second surface of a latch for a seat permit sliding passage of the latch relative to a front leg of a striker, upon contact of the front leg with either of the first and second surfaces. A third surface in a containing space of the latch stops the latch by contacting the front leg. The third surface is arranged such that a rear leg of the striker is brought in alignment with a lock groove of the latch upon contact of the front leg with the third surface. The latch can be guided along the second surface when the second surface contacts the front leg, so that the second surface slides on and past the front leg. By continuously unfolding the seat back upwards until the third surface contacts the front leg, the seat back can be set to a design reference position.

Abstract: A hook lever engages with a striker which enters as far as a deep side in an entering direction of the striker to hold the striker by moving from an opening position to an engagement position while being guided by a hook shaft provided on the deep side in the entering direction of the striker, and a guide lever is guided by the hook shaft and is biased from the deep side to an entrance side in the entering direction of the striker to restrict the movement of the hook lever towards the engagement position, while the guide lever is pressed against by the striker when the striker enters in the entering direction so as to move the hook lever to the engagement position, in such a state that the guide lever is partially overlapped on the hook lever.

Abstract: A latch device includes a base member that has an entering groove having a deep side wall, a latch including an engaging groove having a restraining wall, and a ratchet that meshes with the latch in a meshed position. The latch device further includes a cam member that rotates the latch to a restrained position. In the restrained position, the cam member abuts against the latch to nip a striker between the deep side wall and the restraining wall. The restraining wall includes an inclined surface approaching the deep side wall toward an inlet side of the engaging groove at least in the meshed position.

Abstract: A conventional lock mechanism requires a lock-off operation in order to set a seat back of a seat at a design reference position, as a result of which, the seat can not be smoothly mounted to a vehicle body. In the present invention, a first surface 22a1 and a second surface 22a2 of a latch 22 are each adapted to serve as a permitting guide surface which permits sliding passage of the latch from a front leg 30F of a striker, upon either of the first and second surfaces 22a1, 22a2 being forcibly contacted with the front leg 30F.

Abstract: A latch device comprising: a latch that is rotatably supported by a base member, an entering groove having a deep side wall on a deep side in an entering direction into which a striker enters is formed in the base member, an engaging groove with which the striker engages is formed in the latch, and the latch engages with the striker, thereby rotating the latch from a releasing position to a meshed position where the engaging groove intersects with the entering groove; a ratchet that is rotatably supported by the base member and meshes with the latch in the meshed position, thereby preventing the latch from rotating in a releasing direction; a cam member that is rotatably supported by the base member and rotates the latch to a restrained position where the cam member abuts against the latch to nip the striker between the deep side wall and the engaging groove, thereby restraining the striker.

Abstract: A door latching mechanism of a vehicle door lock engages with a striker fixed to a vehicle body to close a door. An outside handle on the door is operated. Operating force is transmitted via a rod to an intermediate lever below a windowpane in the door and transmitted via a Bowden cable to an operating mechanism. The force is transmitted from the operating mechanism to the door latching mechanism to release the engagement from the latching mechanism to allow the door to open.

Abstract: A biasing structure for biasing a locking pawl-equipped operation rod in a given direction is described. A slit is formed in a rear end of the operation rod. A spring retainer is integrally provided by a bracket through which the operation rod is rotatably connected to a movable rail. The spring retainer includes a rearwardly projected portion whose one surface faces toward a rear end portion of the operation rod and a recess which is formed in a base part of the projected portion and faces toward the rear end portion of the operation rod. A coil spring includes a multi-turned major portion, a front straight portion tangentially extending from a front end of the major portion and a rear straight portion extending radially inward from a rear end of the major portion.

Abstract: A rail unit comprises a fixed rail, a movable rail slidably engaged with the fixed rail and a locking mechanism for locking the movable rail relative to the fixed rail. In order to increase a mechanical strength of a given part of lower flanges of the movable rail where locking openings for the locking mechanism are formed, the given part is integrally formed at an upper end thereof with a raised portion, or the lower flanges of the movable rail are formed at mutually mating portions with depressed portions. When the movable rail and the fixed rail are subjected to a mutually pulled apart movement upon a vehicle collision of the like, the raised portion or the depression portions are brought into abutment with an inner surface of the fixed rail to suppress or at least minimize deformation of the rail unit.

Abstract: A lower rail of channel structure is secured a floor. The lower rail has a longitudinally extending slot in an upper portion thereof. An upper rail is slidably engaged with the lower rail and mounts thereon a seat. The upper rail includes a base portion which is slidably received in the lower rail and a supporting wall portion which extends upward from the base portion and passes through the slot of the lower rail for connection with the seat. A protecting cover covers one end portion of the lower rail and has a longitudinally extending slit into which the supporting wall portion of the upper rail is inserted when the upper rail assumes an extreme position relative to the lower rail. A concealing structure is integral with the projecting cover and constructed to conceal the slit. The concealing structure and the supporting wall portion are so constructed as to permit the insertion of the supporting wall portion into the slit irrespective of provision of the concealing structure.

Abstract: A seat sliding device including a stationary rail secured at both ends thereof to a vehicle floor through brackets, a movable rail slidably engaged with the stationary rail and mounting thereon a seat, and a protective cover for covering the bracket and said stationary rail. The protective cover comprises a bracket cover portion covering the bracket, a rail cover portion connected to the bracket cover portion and covering an end portion of the stationary rail, and means for defining a guide groove which provides a space through which the movable rail passes. The protective cover contributes to an improvement in interior appearance and safety of a passenger compartment of vehicles.
