Energy-absorbing system for vehicle door assembly

A door assembly operatively attached to a body of a motorized vehicle to selectively transition from a substantially closed position to a generally open position, comprising:

• an inner support panel with opposing inboard and outboard surfaces;
• a trim panel member operatively attached to said inner support panel;
• an armrest assembly disposed vertically adjacent said trim panel member and elongated along said inner support panel and extending inward therefrom, said armrest assembly having a pull-handle defining an internal cavity therein;
• a reaction plate member having a generally planar portion with opposing first and second surfaces, said second surface operatively attached to an inner surface of said trim panel member;
• a first bracket member having a first generally vertical mounting portion with first and second leg members extending inward in an arcuate manner from opposing ends thereof, said first and second leg members being operatively attached to said first surface of said reaction plate member;
• a second bracket member longitudinally spaced from and substantially parallel to said first bracket member and having a second generally vertical mounting portion with third and fourth leg members extending inward in an arcuate manner from opposing ends thereof, said third and fourth leg members being operatively attached to said first surface of said reaction plate member;
• and
• a mounting bracket intermediate said inner support panel and said first and second bracket members, said mounting bracket operatively attaching said first and second vertical mounting portions to said inboard surface of said inner support panel;
• wherein said first and second bracket members are configured to sustain a predetermined minimum vertical loading condition and controllably deform under a predetermined threshold lateral loading condition to absorb and attenuate kinetic energy resulting therefrom.

A motorized vehicle having a vehicle body, comprising:

• a door assembly operatively attached to the vehicle body to selectively transition from a substantially closed position to a generally open position, said door assembly including an inner support panel with opposing inboard and outboard surfaces;
• an armrest assembly operatively attached to said door assembly inner support panel and extending inward therefrom, said armrest assembly having a pull-handle defining an internal cavity therein;
• a trim panel member with an inner surface operatively attached to said door assembly inner support panel;
• a reaction plate member having a generally planar portion with opposing first and second surfaces, said second surface operatively attached to said inner surface of said trim panel member, said planar portion including a flange portion extending from an upper peripheral edge thereof, wherein a first section of said flange portion abuts against a b-side surface of said pull-handle internal cavity and a second section of said flange portion abuts against an underside surface of said armrest assembly;
• a first bracket member having a first generally vertical mounting portion with first and second leg members extending inward in an arcuate manner from opposing ends thereof to define a substantially C-shaped configuration, said first and second leg members being operatively attached to said first surface of said reaction plate member;
• a second bracket member longitudinally spaced from and substantially parallel to said first bracket member and having a second generally vertical mounting portion with third and fourth leg members extending inward in an arcuate manner from opposing ends thereof to define a substantially C-shaped configuration, said third and fourth leg members being operatively attached to said first surface of said reaction plate member;
• and
• a mounting bracket intermediate said inner support panel and said first and second bracket members, said mounting bracket operatively attaching said first and second vertical mounting portions to said inboard surface of said inner support panel;
• wherein said reaction plate member is positioned at a longitudinally rearward end of said trim panel member such that said reaction plate member and said first and second bracket members are positioned laterally adjacent a predetermined occupant zone;
• and
• wherein said first and second bracket members are configured to sustain a predetermined minimum vertical loading condition and controllably deform under a predetermined threshold lateral loading condition to absorb and attenuate kinetic energy resulting therefrom.
