Vehicle closure panel having an intrusion beam as primary structure
First Claim
1. A movable closure for selectively covering an opening in a vehicle comprising:
- a primary structural outer frame having at least one frame member for defining an outer periphery, said primary structural outer frame member connected to a secondary structure;
a central beam portion within said outer periphery rigidly connected to said primary structural outer frame wherein said central beam portion includes at least one first U-shaped element having a base and first and second outwardly extending arms having distal ends, said base having a length substantially less than a length of said outer frame;
said distal ends of said outwardly extending arms being rigidly connected to said outer frame; and
an exterior panel connected to and at least partially covering said outer frame.

Abstract
A vehicle closure panel includes an outer frame that is connected to a central beam portion to provide a primary structure that resists deformation and efficiently distributes impact forces during a collision. The present invention can be used with or without structural key members and mating recesses to integrate the closure panel with the rest of the vehicle body, depending on design criteria. Also, primary structure of the present invention provides a structural modularity for closure panels that simplifies design by reducing the number of overall parts and uses the primary structure alone to meet the demands for crash testing. Thus, a basic structure is relied on for crash strength while accompanying secondary structures provide cosmetic differences. The inventive intrusion frame can be used with conventionally hinged passenger doors (both front and rear), vertically sliding doors, rear minivan doors, utility vehicle lift-gates, tailgates, and cargo doors, trunks, sliding van doors, or any vehicle door opening where it is desired to limit intrusion into the vehicle during a collision.

16. A door for selectively closing a vehicle opening comprising:
-
a door ring defining a secondary structure and having a recess defined by a flange;
a tubular impact intrusion frame located in the recess and positioned adjacent the flange, said impact intrusion frame comprising;
a primary structural outer frame having at least one frame member for defining an outer periphery, a central beam portion rigidly connected to said primary structural outer frame so as to be positioned within said outer periphery and including a plurality of outwardly extending arms, each arm have at least one distal end;
said distal ends of said outwardly extending arms being connected to said primary structural outer frame and wherein said central beam portion includes first and second U-shaped elements each having two of said plurality of outwardly extending arms and a base positioned between said outwardly extending arms, said second U-shaped element being positioned in an inverted, overlapping orientation relative to said first U-shaped element such that said bases of said first and second U-shaped elements are spaced apart; and
an exterior panel connected to and at least partially covering said primary structural outer frame. - View Dependent Claims (17, 18)
