Abstract
A tunable knee blocker energy absorption system for a vehicle having an instrument panel, a structural cross-car member, and an occupant protection device includes a left energy absorption (EA) bracket configured to couple to the structural cross-car member and including a left lower EA bracket, a left upper EA bracket, and a left EA bridge. A right EA bracket is configured to couple to the structural cross-car member and includes a right lower EA bracket and a right upper EA bracket. The left EA bracket and the right EA bracket are distinct from each other to manage a non-uniform load path of occupant femurs into the instrument panel and alter the kinematic response of the occupant back to a uniform presentation to the occupant protection device.
