Twist-lock mounting assembly and method for a bumper energy absorber

摘要

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.
