Module for absorbing energy

摘要

The invention relates to a module for absorbing energy from an impact to which the module (3) has been subjected, via deformation, comprising a core (5) made of a polymer foam with a density of at most 0.2 g/cm3 and with a compressive modulus of elasticity of at most 200 MPa measured to DIN EN 826, wherein the core (5) has an at least to some extent enclosing shell (7) made of a polymer material, and/or comprises an insert (15) made of a polymer material, where the density of the polymer material of the shell (7) and/or of the insert (15) is at most 2.0 g/cm3 and its tensile modulus of elasticity is at least 700 MPa, measured to DIN EN ISO 527.
