Patent ID: 8118349

Claim:
A front part structure of a vehicle body having right and left front side frames, each of the front side frames comprising: a compressive load bearing frame member extending in a longitudinal direction of the vehicle body and having a generally U-shaped cross section opening in a lateral inward direction or a lateral outward direction of the vehicle body, the compressive load bearing frame member of the U-shaped cross section having upper and lower walls and a sidewall extending between the upper and lower walls; a bending load bearing frame member branched from a longitudinally central portion of the compressive load bearing frame member and curved inwardly toward a longitudinal centerline of the vehicle body as extending rearwardly of the vehicle body, the bending load bearing frame member having a generally U-shaped cross section opening in the lateral inward direction or the lateral outward direction of the vehicle body, wherein the compressive load bearing frame member has a rear end portion curved inwardly toward the longitudinal centerline of the vehicle body, and at least one first reinforcement bead formed on the sidewall of the rear end portion of the compressive load bearing frame member and extending in a longitudinal direction of the vehicle body; and a floor frame having a front end portion connected to a rear end portion of each of the front side frames, wherein the rear end portion of the compressive load bearing frame member is downwardly curved, and said at least one first reinforcement bead comprises upper and lower first reinforcement beads extending obliquely downward toward the front end portion of the floor frame and longitudinally aligned with upper and lower ends, respectively, of the front end portion of the floor frame.
