  • Patent number: 8292356
    Abstract: A reinforcing member is provided at a lower-outside corner of a side-sill reinforcement so as to extend in the vehicle longitudinal direction including a connection portion of the side sill to a center pillar for straining deformation of the corner. A deformation promoting portion which is provided at an upper portion of the side-sill reinforcement at a specified position which corresponds to the connection portion for prompting deformation of the upper portion of the side-sill reinforcement. Accordingly, a lower vehicle-body structure of a vehicle which can properly restrain the side sill and the center pillar from coming toward the vehicle inside at the vehicle side crash can be provided.
