Abstract
A force level control for an energy absorber is provided for aircraft, and includes an adjustment element and a housing, whereby via the adjustment element, a bending radius of the energy absorber element is continuously adjustable in the housing.
Claims8
An energy absorber for an aircraft having a force level control, the energy absorber comprising:
- a housing;
- an adjustment element;
- a first cover plate;
- and
- an energy absorber element for absorption of an acceleration energy by plastic deformation,
- wherein the energy absorber element comprises a sheet attached to the housing or to the first cover plate and bent by an angle of approximately 180 degrees within the housing, such that the plastic deformation of the energy absorber element takes place within the housing when the energy absorber element is pulled out of the housing,
- wherein via the adjustment element, a bending radius of the energy absorber element is continuously adjustable in the housing, and
- wherein a displacement of the first cover plate by actuation of the adjustment element results in an adjustment of the bending radius of the energy absorber element.

An energy absorber of for an aircraft having a force level control, the energy absorber comprising:
- a housing;
- a first adjustment element;
- a first cover plate;
- a second adjustment element for displacing the first cover plate,
- wherein the second adjustment element is actuatable independently from the first adjustment element;
- and
- an energy absorber element for absorption of an acceleration energy by plastic deformation, the energy absorber element comprising a sheet attached to the housing or to the first cover plate and bent by an angle of approximately 180 degrees within the housing such that the plastic deformation of the energy absorber element takes place within the housing when the energy absorber element is pulled out of the housing,
- wherein via the first adjustment or the second adjustment element, a bending radius of the energy absorber element is continuously adjustable in the housing.
