Abstract: A front vehicle-body structure is provided that allows for lower deceleration for occupants by facilitating breakage of frame members in the event of an oblique collision. Embodiments include a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A first frame connects an upper portion of the suspension housing and an upper portion on a vehicle-width-direction inner side of a dash panel, a second frame connects the upper portion of the suspension housing and an upper portion of a hinge pillar, and a third frame connects a lower portion of the suspension housing and a lower portion on the vehicle-width-direction inner side of the dash panel. In the event of an oblique collision, the first frame and the second frame break inward in vehicle plan view, and the third frame breaks in a Z-shape in vehicle plan view.

Abstract: A shock absorbing member is provided having a sequential destruction capability and protection against electrolytic corrosion on fastening-fixing portions thereof to be fastened to a bumper reinforcement or a vehicle body. Embodiments include a shock absorbing member between a bumper reinforcement and a vehicle body, including a distal end portion fastened to the bumper reinforcement; a base end flange portion fastened to the vehicle body; and an absorbing member body extending in a vehicle front-rear direction and connecting the distal end portion and the base end flange portion. The absorbing member body includes a carbon fiber-glass reinforced plastic layer. Fastening-fixing portions of the distal end portion and the base end flange portion are composed of glass fiber reinforced plastic layers.

Abstract: An impact absorbing structure for a vehicle according to the present invention includes: a resin frame member extending in a vehicle front-rear direction and having an opening portion in a surface thereof on one side in a vehicle width direction; and a strut member disposed in the opening portion of the frame member. The frame member includes a frame body having the opening portion, and a rib protruding at least either upward or downward from the frame body and extending in the vehicle front-rear direction. The strut member is disposed between a pair of opening edges for defining an upper edge and a lower edge of the opening portion and at a position abuttable against the paired opening edges, when the frame member is deformed by input of a load at a time of oblique collision from upward or oblique collision from downward.

Abstract: An impact absorbing structure includes an impact absorbing member made of CFRP, and the impact absorbing member includes a pair of left and right side wall portions and upper and lower coupling wall portions each coupling the side wall portions. Each of the pair of side wall portions includes a plurality of curved portions. Each of the curved portions is formed such that a leftward/rightward direction depth thereof decreases toward a front side. Each of the pair of side wall portions includes: a plurality of first carbon fibers arranged to extend in a forward/rearward direction and constituting most of reinforced fibers contained in the side wall portion; and a plurality of second carbon fibers arranged to extend in a direction intersecting with the first carbon fibers. The plurality of second carbon fibers are arranged at both thickness direction end vicinity parts of each of the side wall portions.

Abstract: A front vehicle-body structure of a vehicle is provided that allows for lower deceleration (so-called G) for occupants in the event of an oblique collision, which involves the largest load input, while restraining a load in a shear direction from being input to connecting portions of frames. A front vehicle-body structure of a vehicle includes a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A plurality of frames connecting the suspension housing and a vehicle cabin structural member are provided, and at least one frame of the plurality of frames is configured to be facilitated to break in a Z-shape in vehicle plan view in the event of an oblique collision.

Abstract: An exhaust system member is provided on a vehicle-width-direction outer side relative to a vehicle body structure such as a side sill, while avoiding widening of the vehicle, enhancing shock absorption performance during a collision, and maintaining rigidity of the vehicle body. Embodiments include an engine disposed forward of a vehicle cabin, an engine exhaust system, and a hinge pillar extending vertically. The exhaust system includes a first exhaust system member beside the hinge pillar in the vehicle front-rear direction from the vehicle-width-direction outer side of the hinge pillar and extending forward of the hinge pillar, a second exhaust system member rearward of the hinge pillar, and a connection part connecting these exhaust system members. The connection part has a smaller length in the vehicle width direction than at least one of the first and second exhaust system members, and overlaps with the hinge pillar in the vehicle front-rear direction.
