Impact damper inna motor vehicle body made of a foam structure whose rigidityncontrolled by a crash sensor is variably adjustable, takingnthe foam is made of a polymer and the pores are fluidnMedium fillednare, with the stiffness or compressibility of the impact damper betweennat least a softer and a harder state reversibly reversiblenis, being hardernCondition of the pressure and / or the viscosity of the fluid medium higher and / ornthe compressibilitynof the fluid medium are set lower than in the softer state. |
