Impact absorber having sensing amplifier

An impact absorber for a bumper assembly, having a crossbeam, of a motor vehicle, comprising:

• a force transmission portion;
• an absorption portion;
• and
• a force transfer portion that is a separate structural element at least partially received within the absorption portion and forming a first load path that at least partially bypasses the absorption portion,
• wherein the impact absorber is fastenable to the crossbeam of the motor vehicle and is provided to at least partially absorb an input of energy acting on the impact absorber during a collision and to provide the input energy to the force transmission portion, which force transmission portion is operatively connectable to a pressure sensor installation, so that the collision is detectable by the pressure sensor installation,
• wherein the force transfer portion is configured to transmit the input of energy acting on the impact absorber during the collision to the force transmission portion while at least partially circumventing regions of the absorption portion thereby forming the first load path, and
• wherein the force transfer portion is configured such that the force transfer portion collapses in an event of an input of energy that is so high that the detection of the collision via the pressure sensor installation is possible without the circumvention of regions of the absorption portion, wherein upon collapse the force transfer portion releases a predefined deformation path and the absorption portion forms a second load path for transmitting the input of energy to the force transmission portion.
