  • Patent number: 8939496
    Abstract: A vehicle structure, comprising a front wheelhouse covering a front wheel, the front wheel comprising a rear face and a slant face which slants forward and inward from an inward end portion, in a vehicle width direction, of the rear face, a footrest, on which a passenger's foot is placed, the footrest being arranged near and on an inward side of the slant face of the front wheelhouse in a plan view of a vehicle, and a gusset connected to the rear face of the front wheelhouse and extending inward from a connection portion thereof to the rear face, wherein an inward end portion, in the vehicle width direction, of the gusset is arranged in the vicinity of a front-side portion of the footrest such that the footrest is restrained from moving forward by contacting the inward end portion of the gusset in a vehicle collision.

  • Patent number: 8820810
    Abstract: An acceleration pedal is arranged on one side, in a vehicle width direction, of a steering column cover covering a steering column so as to move forward or slant forward through a press operation of a press face thereof. A guide face is provided at a specified portion of a lower face of the steering column cover which is positioned in front of a lower-face rear end portion in a steering-shaft axis direction and on an acceleration-pedal-arrangement side, wherein the guide face is configured to project downward below an extension line extending from the lower-face rear end portion in the steering-shaft axis direction and extend forward. Accordingly, a passenger's foot can be properly restrained from moving, in the vehicle width direction, off the pedal in a vehicle head-on collision, ensuring an appropriate ingress-and-egress performance of a passenger.

  • Patent number: 8820787
    Abstract: A knee bolster comprises a curved arm projecting rearward from its one end portion and extending downward in a side view, the other end portion of which is configured as a free end, an inside arm provided inside the curved arm and interconnecting an upper portion and a lower portion of the curved arm, and an impact absorbing member arranged at the other end portion of the curved arm so as to be deformable when the curved arm is deformed by receiving an impact load so that the impact absorbing member is caught between the curved arm deformed and a vehicle-body-side member attached to a vehicle-body member. Accordingly, a load from a knee of a passenger moving forward in a vehicle collision can be received surely and the collision impact can be absorbed properly, thereby protecting the passenger's knee effectively, avoiding improper interference with any surrounding components.
