  • Patent number: 11731711
    Abstract: A vehicle front structure is provided for preventing a vortex from being generated between high-speed air separated from an outer edge of a deflector and low-speed air in a front wheel house due to a wind speed difference. Embodiments include a deflector disposed in front of a front wheel house projected downward from a lower surface of a bumper face. The deflector includes an air introducing section to introduce air into a space inside the deflector in a front portion of the deflector; and an intermediate-speed wind generating hole section that communicates with the air introducing section and generates an airflow at an intermediate wind speed, lower than a wind speed of air separated from deflector outer edges and higher than a wind speed of air in the front wheel house, in an area not opposing a tire in a vehicle front view of a portion immediately behind the deflector.

  • Patent number: 5865496
    Abstract: A door structure of a motor vehicle has an inner panel and an outer panel. The door structure includes an impact load absorber member, provided at an outer panel side of the door, for absorbing and reducing a side collision impact load acting on a passenger by contact with the passenger. An opening is provided in the inner panel for allowing at least one portion of the impact load absorber member to enter. An passenger is compartment of the vehicle during a side collision. A supporting device is provided in the door for supporting the impact load absorber member.
