Definitions

  • the present invention relates to latch arrangements and in particular latch arrangements for releasably securing vehicle doors such as car doors in a closed position.
  • a latch arrangement including a latch bolt connected to release means by a transmission path, normal actuation of the release means causing unlatching of the latch arrangement, the latch arrangement further including an actuator operable to provide a break in the transmission path following the occurrence of a predetermined normal condition of an associated vehicle, the transmission path being re-established by operator indication of an unlatching requirement following the predetermined condition ceasing to exist.
  • a latch arrangement including a latch bolt connected to release means by a transmission path, normal actuation of the release means causing unlatching of the latch arrangement, the latch arrangement further including an actuator operable to provide a block in the transmission path following the occurrence of a predetermined normal condition of an associated vehicle, the transmission path being unblocked by operator indication of an unlatching requirement following the predetermined condition ceasing to exist.
  • a latch arrangement including a latch bolt connected to release means by a transmission path, normal actuation of the release means causing unlatching of the latch arrangement, the latch arrangement further including an actuator which in use automatically operates to provide a break in the transmission path when an associated vehicle is moving above a predetermined speed, the transmission path being re-established by operator indication of an unlatching requirement.
  • a latch arrangement including a latch bolt connected to release means by a transmission path, normal actuation of the release means causing unlatching of the latch arrangement, the latch arrangement further including an actuator which in use automatically operates to provide a block in the transmission path when an associated vehicle is moving above a predetermined speed, the transmission path being unblocked by operator indication of an unlatching requirement.
  • a latch arrangement 10 having a latch bolt in the form of a rotating claw 12 connected to a release means in the form of an inside door handle 14 via a transmission path 16.
  • the rotating claw releasably secures a striker pin 18, allowing the latch arrangement to releasably secure an associated door (not shown).
  • Inside door handle 14 is pivotally mounted about pivot 20 and can move between a latched position as shown in figures 1 and 2 and an unlatched position as shown in figure 3 and 4.
  • the transmission path is shown schematically as three distinct portions.
  • Break portion 26 is connected to actuator 28 which is capable of moving break portion 26 between an engaged position as shown in figures 1 and 4 where the transmission path 16 is complete and a disengaged position as shown in figures 2 and 3 where the transmission path is broken. Operation of the latch arrangement is as follows:-
  • the latch arrangement would be as shown in figure 1 with striker pin 18 retained by the rotating claw 12 and with the break portion in the engaged position and the inside door handle in the latched position.
  • output portion 24 would all be located within a single latch assembly. Furthermore typically output portion 24 would ultimately terminate in a pawl which engages the rotating claw and can retain the rotating claw in a latched and also a first safety position, disengagement of the pawl from the claw allowing the claw to move to its unlatched position.
  • one of the predetermined conditions can be that the vehicle is moving faster than a predetermined speed such as 0 kph, 5 kph, 10 kph, 15 kph.
  • inertia forces will tend to cause the various components of the latch arrangement to move in the direction of arrow A relative to the vehicle 8.
  • input portion 22 might typically be a rod running in a fore and aft direction of the vehicle and inside door handle 14 might be a relatively light component thus the total inertia forces acting on the input portion and inside door handle typically might result in these components moving to the position as shown in figure 3.
  • the latch arrangement remains latched since there is a break in the transmission path between input portion 22 and output portion 24.
  • output portion 24 can be made relatively light since, in practice, break portion 26 is very close to the rotating claw thus the output portion 24 can be arranged to have low inertia, so low in fact that it will not, by itself, cause the door to become unlatched.
  • the predetermined condition When the driver comes to the end of his journey the predetermined condition will cease to exist eg. the vehicle will be stationary or the ignition will be turned off or the engine will be turned off or the parking brake will be applied. Under theses conditions the actuator 28 is not caused to re-establish the transmission path but ensures that the break portion 26 remains in its disengaged position.
  • an unlatching requirement can nevertheless be indicated by a third party such as a member of a rescue service operating the outside door handle.
  • Some vehicles have a three position inside door handle, the three positions being a locked position, a latched position and an unlatched position. Under such circumstances the unlatching requirement could be indicated by the operator moving the inside handle from the locked to the unlocked position, or by moving the inside handle from the locked to the unlatched position, or by moving the inside handle from the latched to the unlatched position.
  • FIG 5 there is shown a further schematic view of a latch arrangement 30 according to the present invention differing from the first embodiment only by the fact that the transmission path 32 does not have the capability of being broken but does have the capability of being blocked by block portion 34 of the transmission path 32 being engageable with block portion 36 of actuator 38.
  • the transmission path 32 does not have the capability of being broken but does have the capability of being blocked by block portion 34 of the transmission path 32 being engageable with block portion 36 of actuator 38.
  • the invention has been described in relation to inside door handles and head on collisions of vehicles, inertia forces can arise in any direction of the vehicle since the vehicle can be involved in a side impact or the vehicle can roll.
  • the invention is applicable to transmission paths orientated in any direction on the vehicle and in particular it is applicable to transmission paths connecting a latch bolt with an external release means such as an outside door handle.
  • the actuator can be that actuator associated with normal locking, normal superlocking, or normal child safety operation.
  • the break (or block) in the transmission path can be automatically provided when the vehicle is moving above a predetermined speed with the transmission path only being re-established (or unblocked) via operator indication of an unlatching requirement.
  • Such a mode of re-establishing (or unblocking) the transmission path is applicable when the vehicle is either travelling above the predetermined speed or below the predetermined speed.
  • the actuator of the present invention typically is only required to perform one cycle during a journey, ie. the actuator provides the break (or block) when the predetermined condition arises and only re-establishes the transmission path (or unblocks it) when the driver exits the vehicle.
  • the actuator is not caused to cycle as the predetermined condition both exists and ceases to exit. For example if the predetermined condition is that of the vehicle moving above five kilometres per hour, every time the vehicle slows to below five kilometres per hour it is not necessary for the actuator to re-establish the transmission path (or unblock it) since generally no operator indication of an unlatching requirement will have been given.
