VEHICLE BODY CONSTRUCTION WITH IMPACT ABSORPTION PART

PROBLEM TO BE SOLVED: To provide a vehicle body construction with an impact absorption part which can absorb light energy at the time of light collision and initial energy at the time of head-on collision and off-set collision without use of a reinforcement member.SOLUTION: A vehicle body construction 10 comprises a frame impact absorption member 30 which extends in a vehicle body longitudinal direction from a left front side frame 13 side. The frame impact absorption member 30 comprises: first and second frame bent members which form a frame cylindrical body 34; upper and lower frame flanges 35, 36 which are expanded outside from the frame cylindrical body 34; upper and lower fragile parts 37, 38 which segment respective frame flanges 35, 36 in the vehicle body longitudinal direction; and plural frame rigid parts 43, 44 which are formed at a rear end part 34a of the frame cylindrical body 34 on the rear side of the vehicle body with respect to respective fragile parts 37, 38.SELECTED DRAWING: Figure 2 【課題】補強部材を用いることなく、軽衝突時の軽エネルギや、前面衝突やオフセット衝突の初期エネルギの吸収が可能な衝撃吸収部材付き車体構造を提供する。【解決手段】車体構造１０は、左フロントサイドフレーム１３側から車体前後方向へ延びるフレーム衝撃吸収部材３０を備える。フレーム衝撃吸収部材３０は、フレーム筒体３４を形成する第１、第２のフレーム折曲部材 と、フレーム筒体３４から外側へ張り出される上下のフレームフランジ３５，３６と、各フレームフランジ３５，３６を車体前後方向で分断する上下の第１脆弱部３７，３８と、各第１脆弱部３７，３８より車体後方のフレーム筒体３４の後端部３４ａに形成される複数のフレーム剛性部４３，４４とを備える。【選択図】図２
