Abstract
A device for the absorption of impact energy in motor vehicles is designed with a box profile section of sheet metal construction fixed in use to at least one bodywork component. In the direction of introduction of a force that is to be absorbed, the box profile section is designed with a tapered extension such that, when compressed by the force to be absorbed, the deformed material accumulates substantially inside the cross-section of the remaining deformation length of the box section profile in a manner at least approximating to a concertina.
Claims8
An assembly for the absorption of impact energy in motor vehicles having a box profile section of sheet metal construction fixed in use to a body component, the box profile section being designed with a tapered extension in a direction of introduction of a force (F) that is to be absorbed,
- wherein the box profile section has creases, at least some of said creases being staggered in relation to one another in a peripheral direction of the box profile section, and
- wherein the creases in an area toward the introduction of the force (F) have a greater depth than creases in an area of the box profile section remote from the introduction of the force (F).
An assembly for the absorption of impact energy in motor vehicles having a box profile section of sheet metal construction fixed in use to a body component, the box profile section being designed with a tapered extension in a direction of introduction of a force (F) that is to be absorbed,
- wherein the box profile section has creases, at least some of said creases being staggered in relation to one another in a peripheral direction of the box profile section, and
- wherein the creases on a top side and a bottom side of the box profile section are arched outwards and the creases on the side faces of the box profile section are arched inwards.
