Release handle assembly having inertial blocking member with blocking member retainer
An inertial blocking member subassembly being part of a release handle assembly associated with a vehicle door, the inertial blocking member subassembly being activated by an acceleration force associated with an impact event, the release handle assembly having a release handle framework supporting a bell crank assembly and a manually actuatable door handle grip, the door handle grip operatively coupled to the bell crank assembly to unlatch the vehicle door upon manual actuation of the door handle grip. The inertial blocking member subassembly includes a blocking member associated with the release handle assembly framework, movable in at least one of rotation about an axis of rotation and translation along the axis of rotation. The blocking member has a center of gravity which is offset from the axis of rotation. The blocking member is movable between an at-rest position, in which the blocking member does not interfere with the bell crank assembly to prevent unlatching of the vehicle door by actuation of the door handle grip, and an engagement position, in which the blocking member interferes with the bell crank assembly to prevent unlatching of the vehicle door by manual actuation of the door handle grip. In the engagement position of the blocking member, the center of gravity is approximately aligned with a vector of the acceleration force and the axis of rotation; whereby, as a result of the acceleration force acting on the blocking member center of gravity, the blocking member is moved to the engagement position.
