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.
  • US4995654 shows a latch arrangement which is normally lockable by operation of an internal sill button or an external key barrel arrangement.
  • the lock mechanism includes various levers, one of which has an extension arm situated on the inside of the external door skin. Deformation inwardly of the door skin causes the extension arm to move the latch mechanism to its normal locked position.
  • latch arrangement as defined in claim 1.
  • latch arrangement as defined in claim 9.
  • a latch arrangement 10 for use with a car side door the latch arrangement 10 including a latch mechanism 12 (only part of which is shown), a transmission path 14 and a release means in the form of an inside door handle 16 (shown schematically).
  • the door would be hinged at a front edge, though in further embodiments this need not be the case.
  • the latch mechanism 12 includes a housing 18 on which is pivoted latch mechanism inside release lever 20.
  • the housing 18 further includes a latch bolt (not shown) for engagement with a striker pin secured to fixed structure of the car such as a B post or a C post.
  • the latch bolt is retained in a close position by a pawl (not shown), thus allowing the latch arrangement to secure the door in a closed position.
  • the pawl is operably connected to the latch mechanism inside release lever 20 via transmission elements (not shown) of the transmission path 14.
  • a rod 22 is pivotally connected at end 22A via pivot 24 to inside door handle 16.
  • the rod 22 is bent at 90° and includes first abutment 26, second abutment 28 and third abutment 30 all being provided on the bent portion of the rod 22. End 22B passes through a hole in latch mechanism inside release lever 20.
  • a resilient means in the form of a spring 32 is mounted on end 22B and abuts third abutment 30 and the edge of the hole in the latch mechanism inside release lever 20.
  • the latch mechanism 12 can be locked and unlocked by actuation of lock lever 34.
  • lock lever 34 When lock lever 34 is in position U, as shown in figure 1, the latch mechanism 12 is unlocked and when lock lever 34 is in position L, as shown in figure 1, the latch mechanism is locked.
  • Locking can be effected by lock lever 34 providing a break in the transmission path whereby operation of inside door handle 16 is possible but has no effect or by lock lever 34 providing a block in the trammission path whereby operation of inside door handle 16 is prevented thus similarly leaving the door in a locked condition.
  • transmission elements of the transmission path include rod 22, inside release lever 20, the pawl and the blocking or breaking element (not shown) connected to lock lever 34. It is the various elements of the transmission path which connect the inside door handle ultimately to the latch bolt.
  • the latch assembly 10 is contained within a door 50, having a door outer skin 51. Connected to an inner portion of the door skin 51 is a defamation abutment 52.
  • deformation 52 is solely provided for transmitting an impact on the door skin 51 to the transmission path.
  • the deformation abutment can form part of further components, for example, window regulator rails.
  • any subsequent deformation of the latch arrangement in particular deformation of the rod 22 which puts the rod into tension and thus potentially causes rotation of the latch mechanism inside release lever 20 will not unlatch the door since the initial deformation put the door into a locked condition. It can be seen that the initial deformation which puts the latch mechanism into a locked condition is allowed for by resilient deformation of spring 32.
  • a contact abutment 52 is located proximal end 22b of rod 22, ie proximal the latch mechanism 12.
  • a second embodiment of a latch arrangement which includes a latch mechanism 112, a transmission path 114, a housing 118, a latch mechanism inside release lever 120, a rod 122 and a spring 132.
  • the latch mechanism further includes a release lever 140 operably situated between the latch mechanism inside release lever 120 and the pawl (not shown).
  • Release lever 140 is pivotally mounted about pivot 142 and includes a tab 144.
  • the latch arrangement 110 is mounted within a door 146 which defines a door plane D.P. Normal operation of the latch arrangement causes rod 122 to move in the direction of arrow C within a movement plane M.P which is generally parallel to the door plane D.P.
  • the invention is not limited to use with a transmission path connecting a latch bolt with an inside handle of a door, in particular the invention could be used in conjunction with an outside door handle of a vehicle.
  • the latch arrangement includes a first transmission path between the latch bolt and an inside door handle and a second transmission path between the latch bolt and outside door handle
  • initial deformation of the latch arrangement could be arranged to cause a first break or block in the in the first transmission path and a second break or block in the second transmission path.
  • the break or block could be provided in the common part of the transmission path thus only requiring one block or break to secure the door from opening.
  • 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 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.
  • the lock lever 34 can either provide such a break or block directly or can act on further levers or the like which themselves provide the break or block.

Claims (12)

  1. Agencement de verrouillage (100) comprenant un loquet relié à des moyens de libération par une ligne de transmission (114), l'actionnement normal des moyens de libération provoquant le déverrouillage de l'agencement de verrouillage, caractérisé en ce que la ligne de transmission (114) est adaptée de sorte qu'une déformation initiale anormale d'une partie de la ligne de transmission provoque une rupture de la ligne de transmission de sorte qu'une déformation anormale supplémentaire de cette partie de l'agencement de verrouillage du côté des moyens de libération de la rupture ne libère pas le verrouillage, dans lequel la ligne de transmission (114) comprend une pluralité d'éléments de transmission (122, 122A, 144) pour lesquels la rupture est assurée par un désalignement d'éléments de transmission (122A, 144) adjacents qui est permis par un déplacement élastique de moyens élastiques (132).
