The honeycomb block, in accordance with the present invention, comprises at least two layers of honeycomb elements. These layers can be of the same or different thickness. Each layer comprises a middle part made up of the honeycomb cells, and two outer sheets delimiting the middle part. The honeycomb cell sizes can be the same or different for the layers. The specific combination of layer thicknesses and cell sizes depend upon the desired energy absorption properties which are to be imparted to the block. Honeycomb blocks according to the invention are particularly useful as side protection/impact force absorbing elements in the doors of vehicles. When using honeycomb element layers with varying cell sizes, the large size cells are usually facing out from the passenger compartment and, hence, the smaller size cells facing inwards. This construction enables an energy absorption with a desired progress, e.g. a smooth capture of a colliding object. |
