INDUS has launched an innovative
knee bolster energy
absorber (EA) using its LATTICELL
Energy Absorber Technology. The product derives
its name from “Lattice
of Cells” and is patent protected
by INDUS. Two LATTICELL EA units, in conjunction
with a custom designed reaction plate, provide a
quantum leap in
vehicle driver protection. Similarly,
two LATTICELL EA units, in conjunction with a custom
designed glove box door, provide a substantial improvement
in front passenger protection.
LATTICELL EA technology can be realized in many ways.
One method utilizes aluminum extrusions made of a specially heat-treated
aluminum alloy with “open cell”
type openings and with multiple cells
arranged strategically. Openings on the curved walls of the cells allow for
crush initiation to occur at the most suitable locations and at the correct
timings. The cell boundary elements plastically deform and efficiently
absorb the energy during knee impacts in a frontal and front-angular crash.
The one-piece extrusion weighs about half a pound.
