Abstract
A reinforced vehicle door assembly more efficiently manages side impact energy by transferring the impact energy through door hinge assemblies to the vehicle frame. The door frame assembly preferably includes first and second reinforcement members or intrusion beams which are attached directly to hinge assemblies. The hinge assemblies have a first hinge member adapted for fixed attachment to the vehicle frame. A second hinge member is pivotally attached to the first hinge member and fixedly attached to a tapping plate. The tapping plate is in turn fixedly attached to the frame of the door. One end of both of the reinforcement members is fixedly attached to an associated one of the mounting plates.
Claims17
A reinforced door assembly for a motor vehicle, the motor vehicle including a vehicle frame, the reinforced door comprising:
- a door frame;
- a hinge assembly operable for pivotally interconnecting the door frame and the vehicle frame, the hinge assembly including a body leaf pivotally connected to a door leaf wherein said hinge assembly includes a first member fixedly attached to the vehicle frame and a second member fixedly attached to the door frame, said first and second members being pivotally interconnected;
- a reinforcement member having a first end directly attached to said hinge assembly such that said door leaf is aligned with a longitudinal axis of the reinforcement member;
- and
- whereby impact energy received by said reinforcement member during a side impact collision is at least partially transferred to the vehicle frame through the hinge assembly.
A reinforced door assembly for a motor vehicle having a vehicle frame, the reinforced door assembly comprising:
- a door frame having an inner panel and a hinge shut face disposed generally perpendicular to said inner panel;
- first and second hinge assemblies;
- and
- first and second intrusion beams both having first ends directly attached to said first and second hinge assemblies, respectively, said first and second intrusion beams being at least partially disposed within a common horizontal plane;
- whereby impact energy received by said first and second intrusion beams during a side impact collision is at least partially transferred to the frame through the first and second hinge assemblies, respectively.
A reinforced door assembly for a motor vehicle having a vehicle frame, the reinforced door assembly comprising:
- a door frame having an inner panel and a hinge shut face disposed generally perpendicular to said inner panel;
- first and second hinge assemblies;
- and
- first and second intrusion beams both having first ends directly attached to said first and second hinge assemblies, respectively, said first and second intrusion beams being at least partially disposed within a common horizontal plane;
- whereby impact energy received by said first and second intrusion beams during a side impact collision is at least partially transferred to the frame through the first and second hinge assemblies, respectively.
A reinforced door assembly for a motor vehicle having a vehicle frame, the reinforced door assembly comprising:
- a door frame having an inner panel and a hinge shut face disposed generally perpendicular to said inner panel;
- upper and lower hinge assemblies;
- and
- first and second intrusion beams both having first ends directly attached to said upper and lower hinge assemblies, respectively, wherein said first and second intrusion beams both horizontally extend substantially across the entire length of said inner panel, and said first and second intrusion beams are at least partially disposed within a common horizontal plane;
- and
- whereby impact energy received by said first and second intrusion beams during a side impact collision is at least partially transferred to the frame through the upper and lower hinge assemblies, respectively.
