Definitions

  • This invention relates to a latch assembly and actuator assembly for a vehicle door.
  • this invention relates to a powered door latch with a manual override.
  • Vehicle door latch systems are well known in the art.
  • a vehicle door will have a latch for engaging and cinching onto a striker.
  • the latch will have a rotatably mounted ratchet engaging a pawl in a ratchet relation.
  • the ratchet cooperates with a mouth of a housing to pivot between an open and closed condition for receiving, engaging and cinching a keeper of a striker.
  • the ratchet has a cam surface having abutment surfaces. As the ratchet engages the keeper of a striker, the ratchet rotates in a latching sense and the pawl travels along the cam surface to retain the ratchet in the closed and cinched conditions.
  • the vehicle door itself has inner and outer manually movable release handles which are operably connected to inner and outer release levers on the latch. To release the latch, the pawl is rotated by responsive movement of either of the inner or outer release levers to disengage the ratchet.
  • powered latch systems as illustrated in WO 98/33998, power actuators are utilized to lock and unlock the latch.
  • These systems embody solenoids, and sometimes, electrical motors with speed reduction gears.
  • the disadvantages of the prior art may be overcome by providing a latch assembly and an actuator assembly for a vehicle having a simple mechanism which will lock and unlock the door latch and also provide a mechanism for a manual override.
  • the latch assembly 10 for a vehicle door is generally illustrated in Figure 1.
  • the latch 10 has a housing 12 having a mouth 14.
  • a ratchet 11 is pivotally mounted to the housing 12 to cooperate with the mouth 14 to pivot between an open condition, as shown in Figure 9, and a closed condition, as shown in Figure 8, for receiving, engaging and cinching a striker 9.
  • a pawl 13 is also pivotally mounted to the housing 12 and biased against the ratchet 11 for maintaining the ratchet in the closed condition.
  • a spring 7 is connected between the ratchet 11 and housing 12 to bias the ratchet 11 in an open condition as commonly known to one of ordinary skill in the art.
  • the latch assembly 10 includes an outside release lever 16 pivotally mounted to the housing 12 at pivot 18.
  • the outside release lever 16 is generally L-shaped and includes heel portion 15 and an opposite C-shaped distal end 17 which is operably connected to an outside door handle on the vehicle door.
  • the latch assembly 10 further includes an inside release lever 20 pivotally mounted by pivot pin 26 to a flange 22 extending generally perpendicularly from the face of the housing 12.
  • the inside release lever 20 has an L-shape and includes a distal end 21 adjacent the mouth 14 of the housing 12 and a toe portion 23 opposite the distal end 21.
  • the distal end 21 connects to a release cable which is operably connected to an inside door handle on the vehicle door.
  • the inside release lever 20 generally operates in a plane orthogonal to the outside release lever 16 as shown in Figure 1.
  • a pawl lever 24 is pivotally mounted on the housing 12 on an opposite side of the housing 12 from the pawl 13 and ratchet 11.
  • the pawl lever 24 is pivotally mounted to housing 12 at pin 36.
  • the pawl lever 24 is operably connected through pin 36 to the pawl 13, on the opposite side of the housing 12, whereby rotation of the pawl lever 24 effects releasing rotation of the pawl 13 which releases the ratchet 11 for opening the latch 10.
  • the pawl lever 24 has tabs 28 on each side thereof and located about mid-length of the lever arm.
  • an outside clutch lever 30 is pivotally connected to the heel portion 15 of the outside release lever 16.
  • the clutch lever 30 is spring biased such that the clutch lever 30 engages one of the tabs 28 on pawl lever 24.
  • An inside clutch lever 32 is pivotally connected to a toe portion 34 of an auxiliary inside release lever 38.
  • the auxiliary release lever 38 is generally L-shaped and pivotally mounted at a heel portion 35 to the housing 12 by pin 40.
  • the distal end 42 of auxiliary release lever 38 engages the toe portion 23 of the release lever 20.
  • the distal end 42 also has a C-shaped portion 44.
  • the auxiliary release lever 38 is spring biased to abut with pin 36.
  • the inside clutch lever 32 is spring biased to engage an opposite one of the tabs 28 on pawl lever 24. That is, the pawl lever 24 is positioned between the outside clutch lever 30 and the overlying inside clutch lever 32 as shown in Figure 1.
  • override lever 46 is commonly mounted on pin 36.
  • the override lever 46 is L-shaped having a toe end 45 and a heel end 47.
  • the toe end 45 supports a pin 48 which engages the C-shaped portion 44 of the auxiliary release lever 38.
  • override lever 46 will responsively rotate therewith.
  • the actuator assembly 50 comprises a housing 52.
  • the housing 52 supports a first motor 54 and a second motor 56.
  • the first motor 54 operates through a series of gears 55 to rotate a shaft 58 which is rotatably mounted within the housing 52.
  • One end of the shaft has a disc 60 which operates a pair of switches 62, 64.
  • the shaft 58 extends longitudinally outside of the housing 52 to a lock cam 66 mounted at the distal end thereof.
  • the lock cam 66 extends into an opening 25 in the housing 12 of the latch assembly 10 and is positioned to engage the clutch levers 30 and 32.
  • the second motor 56 also operates through a series of gears 57 to rotate a shaft 68.
  • the shaft 68 also extends longitudinally outside of the housing 52 to a child lock cam 70 mounted at the distal end thereof.
  • the child lock cam 70 extends into the opening 25 in the housing 12 of the latch assembly 10 and is positioned to engage the inside clutch lever 32.
  • the lock cam 66 has a first lobe 72, a second lobe 74 and a third lobe 76.
  • the first lobe 72 is sized and positioned to engage the outside clutch lever 30.
  • the second lobe 74 is sized and positioned to engage the inside clutch lever 32, but only after the lock cam 66 has rotated a predetermined amount, preferably 70.
  • the third lobe 76 is sized and positioned to engage the override lever 46 only when the lock cam 66 has rotated the predetermined amount of rotation.
  • the third lobe 76 is diametrically opposed to the first lobe 72.
  • the lock cam 66 is rotatable between three different states or conditions: 1) an unlock condition, 2) a single or outside lock condition and 3) a double lock condition. In the unlock condition, the lock cam 66 does not engage either of the clutch levers 30, 32.
  • child lock cam 70 is positioned to engage the inside clutch lever 32.
  • the child lock cam 70 is rotated by the motors 54, 56 to engage the end of the inside clutch lever 32 to cam the inside clutch lever 32 out of engagement with the tab 28 on the pawl lever 24, rendering the inside release lever 20 ineffectual.
  • the override capabilities of the inside release lever 20 is still activated. Operation of the inside release lever 20 will still operate to unlock the latch assembly 10 from the single lock to the unlock condition, allowing releasing by outside release lever 16.
  • the lock cam 166 has a single lobe which engages both of the clutch levers 30 and 32 on rotation thereof a first predetermined amount.
  • the lock assembly 10 has only an unlock condition and a double lock condition with inside release override.
  • the lobe 176 remains in position to engage the override lever 46.
  • a first pull of inside release lever 20 rotates the lock cam 166 from the locked condition to the unlocked condition and then a second pull will unlatch the latch assembly 10.
