Abstract: A modular energy absorber 10 that is tunable. It comprises one or more energy absorbing modules 12. The energy absorbing modules have means for coordinating energy absorbing units 16 of the one or more modules. The means 14 for coordinating position and support the units in relation to each other before, during and after relative motion between an incident object and the energy absorber. A crushable member is provided that has an upper perimeter, a lower perimeter and an intermediate section extending therebetween. It also includes a number (m) of breaches defined therein before impact.

Abstract: A trim panel (1) and a method of making a trim panel (1) comprising providing a formable sheet (12) having at least one layer, locating the sheet (12) adjacent to a forming surface (80), conforming the sheet (12) to the forming surface (80) so that the sheet (12) has a characterizing topography (15) and removing the sheet (12) from the forming surface (80). A substrate (40) is provided having a rear surface (45) and an opening (55) therethrough. Lastly, the sheet (12) is attached to the rear surface (45) of the substrate (40) so that the characterizing topography (15) extends through the opening (55). Alternatively, the sheet (12) may comprise at least one tab (17) and the substrate (40) may comprise at least one tab opening (57) wherein the tab (17) is inserted into the tab opening (57) to snap-fit the pieces together.

Abstract: An energy absorber comprising a base and a plurality of recesses extending from the base. At least some of the plurality of recesses have a rim, a first wall extending between the base and the rim, a first floor, and a second wall extending between the rim and the first floor. At least some of the plurality of recesses are oriented such that their first and second walls are inclined respectively at angles alpha and beta to a major incident component of the impacting force, where alpha and beta lie between 1 and 45 degrees.

Abstract: A composite modular energy absorbing assembly with one or more gamma structures 100 that are interposed with one or more delta structures 200. The gamma structures have a base 12′ and a plurality of recesses 16′ defined therewithin. The recesses 16′ have at least one wall 20′ extending from the associated base 12′. At least some of the recesses 16′ are oriented such that their walls are substantially parallel to a major incident component of an impacting force. The walls 20′ collapse. The delta structures 200 have a lattice 210 of interconnected strands which intersect to define a plurality of cells 220. The plane of at least some of these cells are substantially parallel to the impacting force. The lattice collapses during energy absorption. The composite assembly serves to decelerate an object that impacts thereupon in order to maximize energy absorption over a given distance.
