| 摘要 |
A frame structure capable of increasing collision energy absorption includes a floor member. The floor member has extruded side sill members which are adapted to undergo lateral buckling response to side collisions while resisting axial or longitudinal deformation due to end-on collisions. Extruded impact dispersing deformable sections with a smaller rigidity than the associated side sills are provided on the inboard sides of the sills and arranged to smooth buckling and disperse collision energy. At least one extruded, flat, passenger occupancy floor section, which is located inboard of the impact dispersing deformable sections, is provided to prevent buckling deformation and assure cabin space.
