Abstract
An inertia blocking mechanism operably connected to a door handle on a vehicle having a handle chassis. A counterweight is operably connected to the handle chassis and is pivotally rotatable about a first pivot axis between a non-actuated position and an actuated position. Stanchions extends from the handle chassis. A spring-biased primary inertia lever is operably connected with the stanchions and is pivotally rotatable about a second pivot axis. The spring-biased primary inertia lever is biased to a first position out of rotational alignment with the counterweight. An auxiliary inertia lever is pivotally rotatable about the second pivot axis and is adapted to move the primary inertia lever into a second position in rotational alignment with the counterweight, which prevents the counterweight from rotating downward into the actuated position, thereby actuating the exterior door handle thereby preventing the exterior handle from actuating and releasing the latch.
