Abstract
An energy-absorbing system for vehicle door assemblies is provided, including first and second brackets and a reaction plate. Each bracket attaches to an inner support panel of the door assembly via a mounting portion having leg members extending inward from opposing ends thereof. The reaction plate includes a generally planar portion with a flange portion extending from an upper edge thereof. One side of the reaction plate is attached to an inner surface of a trim panel, whereas the other side is attached to the leg members of the first and second brackets. One section of the flange portion abuts against an underside surface of an armrest assembly, and another section abuts against a b-side surface of a pull-handle. Both brackets are configured to sustain a minimum vertical loading condition (limit vertical deflection), and controllably deform under a threshold lateral loading condition to absorb and attenuate kinetic energy resulting therefrom.
