An impact energy absorbing knee bolster system (1) is basically provided with a load input part (11) and a deformation accepting structure (12A,12B,12C,12D). The load input part is arranged to contact a passenger's knee during a collision. The deformation accepting structure is located between a load input part and a vehicle structural member (6) to deform in response to an impact load imparted by the passenger's knee during a collision. The deformation accepting structure includes a plurality of collapsing parts forming wedge-shaped spaces (21A,21B,21C,21D) between each of the collapsing parts and the load input part. Each of the collapsing parts has an inflection point (P1,P2,P3,P4) with a longitudinal position between a forward end and a rearward end with the longitudinal positions of the inflection points being different for an upper one of the collapsing parts than for a lower one of the collapsing parts. |
