Double material - energy absorption - device with a low heat sensitivity, vehicle the fore-part and motor vehicle, which involves a device of this type.

摘要

The energy absorption - device (5) for a motor vehicle comprises:– a first energy absorption - element (50) of a first plastic material, which is provided, in order to be under the effect of an impact of a specific energy by absorption of a first part of the energy of the said impact to plastically deform;– a second energy absorption - element (52) is made of a second plastic material, which differs from the first plastics material, which is provided in such a way, in order to be under the effect of an impact of a specific energy by absorption of a second part of the energy of the said impact to plastically deform;– the first and second energy absorption - element (50, 52) are adapted such that the energy absorption - device (5) at each temperature of between – 30°C. and 80°C, including a total of intrusion resistance force between 75 and 200 kn has including.
