Definitions

  • FIG. 1 is a fragmentary plane view of a car frame in accordance with one preferred embodiment of the present invention
  • FIG. 5 is a cross-sectional view taken on a line VV in FIG. 3,
  • FIG. 9(A), (B) AND (C) illustrates deformed condition of a conventional structural frame
  • bowl-shaped projections 7a and 7b abut against those two inner sides 10 and 11 of the inner sides of the structural frames 1 and 2 which oppose in the direction of curvature.
  • a structural frame capable of absorbing impact energy comprising structural frame members made of metal defining closed rectangular crosssection, a portion of each of said structural frame members being bent in the direction perpendicular to the longitudinal direction of the structural frame members, and energy absorption materials made of the metal having bowlshaped projections at its bottom and mounting flanges at its opposite sides of the opening to the projection which are attached to those two opposing inner surfaces of the structural frame which oppose in the direction of bending whereby the bowl-shaped projections may abut against each other.
