Patent ID: 8573683

Claim:
A front structure of a vehicle comprising: a pair of front rails, wherein said pair of front rails are spaced apart in a widthwise direction relative to said vehicle, wherein each of said pair of front rails extend in a lengthwise direction relative to said vehicle, wherein said pair of front rails comprise a front left hand rail and a front right hand rail, wherein a first end portion of said front left hand rail is mechanically coupled to a left portion of a vehicle bumper and a first end portion of said front right hand rail is mechanically coupled to a right portion of said vehicle bumper, wherein a second end portion of said front left hand rail distal from said first end portion of said front left hand rail is mechanically coupled to a left hand torque box, wherein a second end portion of said front right hand rail distal from said first end portion of said front right hand rail is mechanically coupled to a right hand torque box, wherein each of said pair of front rails is comprised of a polygonal-shaped upper hollow channel and a polygonal-shaped lower hollow channel, and wherein said polygonal-shaped upper hollow channel and said polygonal-shaped lower hollow channel share a common wall; and a pair of rail reinforcement members completely contained within said pair of front rails when mounted, wherein a first rail reinforcement member of said pair of rail reinforcement members is mechanically mounted within said front left hand rail and a second rail reinforcement member of said pair of rail reinforcement members is mechanically mounted within said front right hand rail, wherein said first rail reinforcement member is comprised of a first plurality of features that determine front left hand rail reactions to front impact loads, and wherein said second rail reinforcement member is comprised of a second plurality of features that determine front right hand rail reactions to front impact loads.
