    摘要: In an undercover structure according to the present invention, a first cover part that is a lowermost part of an undercover has a first rear end positioned ahead of a front wheel axle. Further, a curved part with a predetermined curvature is formed at the first rear end of the first cover part in a side view. This generates a strong negative pressure in a region ahead of the front wheel axle 21. Accordingly, the flow rate of air flowing to each wheelhouse 23 decreases (the flow rate of the airflow between a road and a vehicle generated along the bottom surface of the first cover part 15a of the undercover 15 increases). This causes an attraction force that attracts the vehicle to a road surface to act on a vehicle body of the vehicle, thereby making traveling stability more excellent.

    摘要: A crash attenuator includes a frame having a first frame member and a second frame member rigidly connected with a hinge assembly in a pre-impact configuration. The first and second frames are hingedly connected with the hinge assembly in an impact configuration. The hinge assembly includes a release plate fixedly connected to the first frame member, wherein the release plate comprises a fastener opening and a slot extending between the fastener opening and an edge of the release plate, and a fastener extending through the fastener opening and connecting the release plate to the second frame member when the first and second frames are in the pre-impact configuration. A hinge assembly, and method of using the crash attenuator, are also provided.
