  • Patent number: 5273330
    Abstract: The present invention includes a mounting assembly for securing an energy absorber unit to vehicular support. A collar having a hub portion is secured to the energy absorber. The hub portion includes at least one circumferential ramp and flange. A mounting plate having at least one tab is secured to the vehicular support. As the collar is placed adjacent the mounting plate, the ramp is rotated into a slip fit with the tab. Preferably, a locking projection of the mounting plate is received in an opening on the flange of the collar to prevent inadvertent rotation of the collar out of a secured position. Also, an alignment key and notch can be formed on the mounting plate and collar, respectively, to facilitate proper orientation of the collar during installation.

  • Patent number: 4976489
    Abstract: An air dam attaches to the underside of a motor vehicle and extends downwardly therefrom into proximity with the road surface and potential interference with curbs or like obstructions extending above the road surface. The air dam is comprised of a generally rectangular flexible sheet with an upper edge and a lower edge defining an air deflecting surface therebetween. A bracket attaches the upper edge of the flexible sheet to the underside of the motor vehicle with the air deflecting surface cantilevered generally horizontally forward from the bracket so that the lower edge is spaced substantially above the road surface.
