Deformation element for front region of motor vehicle, has chamber wall with openings dimensioned, such that fluid easily escapes chamber, during temporary force effect, where element has high rigidity during sudden excessive force effect

摘要

The deformation element (3) has a chamber filled with a fluid (5), where the chamber is defined by walls (7, 9). The wall (9) includes openings (11), through which the fluid escapes from the chamber, during an increase in pressure in the chamber. The openings are so arranged and dimensioned, such that the fluid easily escapes the chamber, during temporary local force effect on the deformation element. The deformation has a high rigidity during a sudden excessive force effect.
