  • unlatching means selectively operable to disengage the latching pawl for opening the
  • said unlatching means comprising a pawl lifter moveable from a position
  • the unlatching means further includes guide means
  • the assembly further includes an over-riding formation
  • Fig.l is a perspective view of a vehicle door latch assembly with some parts not relevant to the invention removed for clarity,
  • Fig.2 is a front elevation thereof with unlatching mechanism in a rest condition
  • Fig.3 is a like elevation with said mechanism in another position
  • Fig.4 is a perspective diagram of plunger guide means of said mechanism.
  • the latch assembly which will be operatively mounted in a door (not shown) in a known manner, includes a conventional rotating latch claw 10 having a mouth 12 for coacting with a striker (not shown)
  • a latching pawl 16 self engages with the claw in known manner to retain it, and hence the door, releasably at a first safety position at which the door is near closed, and an inner position shown in Figure 2 at which the door is fully shut.
  • the assembly may include provision for powered closing/latching of
  • Unlatching means includes a pawl lifter 20 in the form of a two armed lever pivoted co-axially with pawl 16 which engages the latter when angularly
  • Manually operable release means includes a manual release lever 21, also
  • Lever 21 is coupled to
  • a manual release member of the door (not shown) e.g. a door handle, is coupled to lever 21.
  • Power operated unlatching means of the assembly includes an electric motor 22 operable in either direction of rotation.
  • An output member in the form of a release plunger 28 is pivotedly
  • plunger 28 When plunger 28 is aligned rectilinearly with worm 24 its upper end will engage and displace an arm of pawl lifter 20 as shown in Fig.2 when the
  • plunger 28 can also be angularly
  • the path of movement of plunger 28 is controlled by guide means including a track formation 30 shown in detail in Fig.4 carried on a base plate
  • Follower 32 comprises a tubular housing locating
  • a follower pin (not shown) resiliently urged by a spring into engagement with track formation 30 on an axis parallel to but spaced from the pivot axis of
  • track formation 30 has a peripheral guide wall 34 and, within the hollow recess framed by that wall, a earning ramp 36 half way
  • ramp 36 is angled upwardly outwards of the recess and its upper face is angled
