Claim:
1. An inertial blocking member subassembly for a vehicle-door release handle mechanism including a release handle framework supporting a bell crank actuator and a manually actuatable door handle grip, the door handle grip operatively coupled to the bell crank actuator, the inertial blocking member subassembly comprising: an inertial blocking member associated with the release handle assembly framework, the blocking member having a mass defining a center of gravity which is offset from an axis of rotation, and the blocking member being rotationally and/or translationally movable between an at-rest position, in which the blocking member does not prevent actuation of the release handle, and an engaged position, in which the blocking member prevents actuation of the release handle; a discrete accelerator body freely mounted relative to the inertial blocking member for rotational movement about the axis of rotation, the accelerator body having a mass defining a center of gravity which is offset from both the axis of rotation and center of gravity of the inertial blocking member; whereby, as a result of a negative acceleration force acting on the accelerator body center of gravity, the accelerator body rotates about the axis of rotation and carries the blocking member toward the engaged position thereof; whereby, as a result of the negative acceleration force acting on the blocking member, the blocking member does not independently move toward the engaged position thereof; and whereby, as a result of a positive acceleration force acting on the blocking member center of gravity, the blocking member is rotationally and/or translationally moved into the engaged position thereof.
