Abstract
Official abstract text for this publication.
A bead portion is provided at a compression-side wall portion to be recessed toward an inside of a main closed cross section. A first reinforcing member is provided in the closed cross section and joined to a tension-side wall portion so as to form a first sub cross section extending in a longitudinal direction between the tension-side wall portion and the first reinforcing member. A second reinforcing member is provided in the closed cross section and joined to a portion of the compression-side wall portion where the bead portion is provided so as to form a second sub cross section extending vertically between the portion of the compression-side wall portion and the second reinforcing member. The first and second reinforcing members are configured to be spaced apart from each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A frame structure for a vehicle, in which a frame having a rectangular closed cross section is configured to bend when receiving a vehicle collision load, the bending frame comprising a compression-side panel, a tension-side panel, and a pair of short side panels which connect respective upper and lower end portions of the compression-side panel and the tension-side panel, the frame structure for the vehicle comprising: a bead portion provided at the compression-side panel of the frame to be recessed toward an inside of the closed cross section of the frame and extend toward the pair of short side panels of the frame; a first reinforcing member provided in the closed cross section of the frame and joined to an inner face of the tension-side panel of the frame so as to form a first sub cross section extending in a longitudinal direction of the frame between the tension-side panel of the frame and the first reinforcing member; and a second reinforcing member provided in the closed cross section of the frame and joined to an inner face of a portion of the compression-side panel of the frame where the bead portion is provided so as to form a second sub cross section extending toward the pair of short side panels of the frame between the portion of the compression-side panel of the frame and the second reinforcing member, wherein said first and second reinforcing members are configured such that respective inside end portions thereof are spaced apart from each other. 2. The frame structure for the vehicle of claim 1 , wherein said second reinforcing member includes a pair of leg portions which are joined to said inner face of the portion of the compression-side panel of the frame such that said bead portion is interposed between the pair of leg portions of the second reinforcing member. 3. The frame structure for the vehicle of claim 1 , wherein said second reinforcing member is configured to vertically extend substantially over an entire range of said compression-side panel of the frame. 4. The frame structure for the vehicle of claim 1 , wherein said first reinforcing member is comprised of two members which are provided separately from each other such that two independent first sub cross sections extend in the longitudinal direction of the frame. 5. The frame structure for the vehicle of claim 4 , wherein said first reinforcing member is made of a single plate such that a middle portion of the single plate which is positioned between said two independent first sub cross sections is joined to said tension-side panel of the frame. 6. The frame structure for the vehicle of claim 1 , wherein said compression-side panel and said pair of short side panels are made of a single plate, and said pair of short side panels include a pair of flange portions which are joined to respective end portions of said tension-side panel.
