Definitions

  • the invention relates generally to a vehicular door handle and more particularly to an external vehicular door handle having a secondary latch to prevent undesired opening of the vehicular door as a result of impact to the vehicle.
  • Vehicular doors typically comprise a primary latch for retaining the door in a closed position, a handle mechanism mounted on the exterior surface of the door for selectively actuating the primary latch so that the door can be moved to an open position, and a lock for selectively preventing movement of the handle mechanism and, thus, actuation of the primary latch. Consequently, when the door is locked, it cannot be inadvertently opened, such as during impacts resulting from collisions with other vehicles or with stationary objects. However, if the door is unlocked, such impacts can result in undesired inertial movement of the handle, which can thereby actuate the primary latch and open the door. If the door opens during a collision, passengers in the vehicle can be thrown from the vehicle or otherwise injured.
  • active latches require the user to perform a two-step door opening process: a first step to inactivate the secondary latch and a second step to actuate the primary latch to open the door. Users can become irritated and annoyed with the two-step process, especially if the user needs to open the door quickly, such as when the user's hands are full or during inclement weather.
  • the at least one foot can be moved out of engagement with the interference surface by the movement of the latch member against the planar member to thereby enable the handle grip to move to the actuated position.
  • Fig. 15 is a schematic sectional view similar to Fig. 14, wherein the secondary latch is in the inactive condition and the primary actuator is in an opened position.
  • Fig. 19 is a schematic sectional view of a sixth embodiment vehicular door handle assembly according to the invention, wherein the secondary latch is in an active condition and the primary actuator is in a latched position.
  • Fig. 39 is an exploded bottom view of the vehicular doorhandle assembly shown in Fig. 38.
  • Fig. 41 is a sectional view taken along line 41-41 of Fig. 40, wherein the secondary latch is in an active condition and the primary actuator is in a latched position.
  • the door handle assembly 10 is characterized with respect to a forward, rearward, upper, and lower orientation, wherein forward is toward a front end of the vehicle, rearward is toward a rear end of the vehicle, upper is away from the vehicle door, and lower is closer to the vehicle door.
  • This orientation is for exemplary purposes only and is not meant to limit the invention in any manner. It will be apparent to one of ordinary skill in the vehicular handle art that the door handle assembly 10 can be positioned on a vehicular door in any suitable fashion.
  • a pivot member 80 extends from the forward end 72 of the housing 16 and, when the door handle assembly 10 is mounted to the door panel 26, through an aperture in the door panel 26 and into an interior side 27 of the door panel 26 to pivotally connect with a corresponding pivot support member (not shown) in the door. Hence, the housing 16 and the components supported thereby can pivot about the pivot member 80 and relative to the door panel 26.
  • a primary latch actuator 86 with a primary latch actuating arm 88 extends from the second lower wall 90 such that when the door handle assembly 10 is mounted to the door panel 26, the primary latch actuator 86 extends through an aperture in the door panel 26 to reside on the interior side 27 of the door panel 26.

  • the secondary latch 22 comprises a rectangular latch body 132 with a tapered rearward end 134, a forward end 136 with a pair of flanges 130 sized for receipt in the grooves 114 of the trigger 18.
  • movement of the latch body 132 is guided by the bearing 20, which comprises a generally rectangular parallelopiped body 120 having a central passageway 124 sized and shaped for receiving the latch body 132.
  • the body 120 further comprises opposing outer grooves 122 sized to mate with the projections 92 on the housing 16 for mounting the bearing 20 to the housing 16.
  • the ability of the primary actuator to move from the latched position is controlled by a secondary actuator in the form of the trigger 18. Movement of the trigger 18 from the secure position to a release position deactivates the secondary latch 22 so that the primary actuator can move from the latched position.
  • the secondary actuator defaults to the secure position, wherein movement of the primary actuator from the latched position is prevented. However, the secondary actuator can move from the secure position to a release position, wherein the primary actuator is able to move from the latched position.
  • the secondary actuator comprises a second user interaction portion that the user grasps to move the secondary actuator from the secure position to the release position. In this embodiment, the trigger grip 100 functions as the second user interaction portion.
  • the first and second user interaction portions are aligned such that when a user grasps the door handle assembly 10 in order to open the door, the user must grasp both the primary actuator and the second actuator simultaneously.
  • the user grasps both the first interaction portion defined by the arcuate cutouts 38, 78 and second user interaction portion formed by the trigger grip 100.
  • the housing 16 is mounted to the vehicle door panel 26 such that the pivot member 80 and the primary latch actuator 86 are on the interior side 27 of the door panel 26, and the rest of the housing 16 is located on the exterior side 28 of the door panel 26.

  • the trigger 18 is pivotally mounted to the housing 16 and operatively engages the secondary latch 22 to move the secondary latch 22 between the active and inactive conditions.
  • the trigger 18 is positioned such that the crossbar 84 of the housing 16 sits in the channels 110 formed by the hooks 108 of the trigger mount 109, and the trigger 18 can pivot about an axis coincident with the crossbar 84.
  • the secondary latch mounts 111 project into the housing 16 at the rearward end 74 and slidingly receive the flanges 130 of the secondary latch 22.
  • the grooves 114 between the arms 112 of the secondary latch mounts 111 slidingly receive the flanges 130 of the secondary latch 22.
  • the trigger 18 When the trigger 18 is in the secure position, the trigger 18 forces the secondary latch 22 rearward to the active condition wherein the rearward end 134 of the latch body 132 resides in the secondary latch channel 62. Forward movement of the secondary latch 22 is prevented by the arms 122 of the secondary latch mounts 111.
  • the housing 16 cannot move relative to the end cap 14 or the door panel 26; therefore, the door handle assembly 10 cannot pivot about the pivot member 80. Hence, the primary actuator cannot be inadvertently moved to the opened position, and the door is prevented from undesirably opening. Due to the biasing member 24, the trigger 18 is normally in the secure position and, thus, the secondary latch 22 defaults to the active condition and will remain in the active condition until the user actuates the trigger 18.

Because the trigger grip 100 is aligned with the arcuate cutouts 38, 78, the user also grasps the trigger 18 when the user grasps the handle grip 12 and the housing 16.

In the second stage, the user pivots the trigger 18 against the bias of the biasing member 24 and towards the upper wall 70 of the housing 16 to the release position. Because the arms 112 and grooves 114 are inclined, the trigger 18 pulls the secondary latch 22 forward to the inactive condition wherein the rearward end 134 no longer resides in the secondary latch channel 62, as shown in Fig. 4.
