Definitions

  • the present invention relates to latch assemblies and in particular latch assemblies for releasably securing vehicle doors such as car doors in a closed position.
  • a latch mechanism being lockable and having a latch bolt for engagement with a striker, the bolt having at least an open condition for releasing the striker and a closed condition for retaining the striker, the latch mechanism also having an impact over travel closed condition in which a detection means is capable of detecting the impact over travel closed condition of the latch mechanism and then effecting locking of the latch mechanism.
  • a latch mechanism 10 mounted on a car door (not shown) the latch mechanism includes a retention plate 11 having a mouth 12 with a mouth end 12A. Pivotally mounted via pivot 15 situated on the retention plate 11, is a latch bolt in the form of a rotating claw 14.
  • Claw 14 can be retained in a closed position as shown in figures 1 and 4 by a pawl (not shown) thus securing a striker 16 which is mounted on fixed structure of a vehicle, such as a B post or C post of a car.
  • Actuation of the pawl allows the claw to rotate anticlockwise when viewing figures 1 and 4 thus releasing the striker and allowing the door to open.
  • the door typically includes weather seals which are compressed when the door is in the closed position to exclude rain water, dirt and the like from the interior of the vehicle.
  • the latch mechanism 10 is electrically lockable via central door locking system.
  • the latch mechanism further includes detection means in the form of a switch 18 (see figures 4 and 5).
  • the switch engages a cam surface 20 of the claw 14.
  • the cam surface includes an impact over travel portion 24 and a door ajar portion 26 between which is situated a door closed portion 22.
  • control system may effect locking of some or all other doors of the central door locking system.
  • Table 1 shows the various permitations of switch conditions.
  • the central door locking control system it is also possible to arrange for the central door locking control system to not lock the door or doors under certain circumstances such as when the ignition switch is off (and the vehicle is therefore stationary).
  • a car door can be locked whereby operation of an outside door handle does not open the latch, or whereby operation of an inside door handle does not operate the latch (also known as a child safety condition) or the door can be locked such that operation of either the outside or inside door handle does not operate the latch (known as a super locked or dead locked condition) and the present invention is applicable to all these types of locking.
  • locking can be effected by providing a break between a door handle and the claw such that the door handle ⁇ free wheels' without opening the latch, or locking can be provided by creating a block between the door handle and claw such that the block prevents movement of the door handle and the present invention is applicable to ⁇ break' or 'block' type locking.
