Abstract
An energy absorber for a vehicle, comprising: a continuous beam to extend across a width of vehicle, the beam defining a plurality of inward facing cavities in a center section, with adjacent inward facing cavities separated from one another by an inward facing rib, and at each end portion a plurality of outward facing cavities, with adjacent outward facing cavities separated from one another by an outward facing rib, wherein the center section includes a panel that is continuous on its outward side, and that forms a relative bottom of each of the plurality of inward facing cavities with its inward face.
Claims18
An energy absorber for a vehicle, comprising:
- a continuous beam to extend across a width of vehicle, the beam defining a plurality of inward facing cavities in a center section, with adjacent inward facing cavities separated from one another by an inward facing rib, and at each end portion a plurality of outward facing cavities, with adjacent outward facing cavities separated from one another by an outward facing rib,
- wherein the center section includes a panel that is continuous on an outward side of the panel, and that forms a relative bottom of each of the plurality of inward facing cavities with an inward face of the panel;
- and
- wherein each of the end portions forms a respective crash can.
A corner energy absorber comprising:
- an upper wall;
- a lower wall;
- a longitudinal rib disposed between the upper wall and lower wall;
- wherein the longitudinal rib does not intersect at least one of the upper wall and the lower wall;
- a lateral rib extending between the upper wall and the lower wall, and intersecting the longitudinal rib;
- and
- a surface that intersects the upper wall, the lower wall, the longitudinal rib, and the lateral rib and forms a crush box;
- wherein the surface extends along a first side along an end section;
- wherein the surface crosses from the first side to a second side along a transition section;
- wherein the transition section comprises one or more crush boxes on both sides of the surface that have open sides facing away from one another;
- wherein the energy absorber is formed as a single article;
- and
- wherein the energy absorber is configured for attachment to a vehicle.
