Embodiment Construction

[0046] Referring to the drawings, wherein like reference numerals correspond to like or similar parts throughout the several views, and are denoted by figure 1 Initially, a vehicle 10 includes a body 11 that defines an interior 12 . Body 11 may be configured as a passenger car body as shown, or as a truck body, sport utility vehicle body, utility vehicle body, or any other desired body style. Regardless of the configuration of the body 11 , the vehicle 10 includes at least one door assembly or door 14 having a window pane 13 and a lever-type outside (O / S) door handle 16 configured to facilitate access to the vehicle interior 12 . That is, a threshold force applied to the handle 16 in the direction indicated by arrow A will open the door 14 while the door 14 remains latched but unlocked.

[0047] refer to figure 2 , the handle 16 is connected with the internal assembly 17 and the latch mechanism 22 through an inertial lock 24 . The inertia lock 24 is cable actuated as noted e...

Abstract

A vehicle includes a door assembly having an outside door handle, a latching assembly, and a cable-actuated inertial lock having a moveable linkage disposed within a cavity of a stationary housing. A first end of the cable is connected to the handle, and a second end is connected to the linkage. The inertial lock includes a lever for actuating the latch under normal conditions when the handle is actuated, and also contains a deployable toggle piece that is stowed in the linkage. The toggle piece is configured to rotate within the linkage, and thereafter lock against a shaped inner surface of the housing in response to a threshold acceleration of the type set forth in FMVSS 206 or other standards. A torsion spring may be used to bias the toggle piece into a stowed position within the linkage.

Description

technical field [0001] The present invention relates to a vehicle exterior door assembly having a pull-rod exterior handle and a passive latch for preventing opening of a vehicle door during a threshold acceleration event. Background technique [0002] The exterior door handle assemblies of modern vehicles typically employ a pull-rod handle that includes a handle mount. The chassis and any interconnected latch mechanisms may be pre-assembled within the cavity of the vehicle door. In order to prevent inadvertent actuation of the handle during threshold lateral and / or longitudinal acceleration (referred to below as a threshold acceleration event), a vehicle door handle assembly is required to meet certain performance criteria. For example, the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation establishes various minimum performance requirements for vehicle system hosts. [0003] For door handle assemblies specifically, the Federa...
