Abstract
A deformation element is arranged in vehicle pillars and/or between an inside roof lining and a transverse roof support and comprises U-beam shaped elements connected through connecting ribs to form a unit. Reinforcement ribs are provided within the U-shaped beams of the deformation element.
Claims54
An energy-absorbing deformation element for use in pillars, supports and components for motor vehicles arranged in a body structure between a panel element and an interior material, comprising a latticed element,
- wherein the deformation element comprises U-beams arranged at a distance to each other, each of the U-beams having a transverse rib and reinforcement ribs arranged transversely between legs of the U-beams, and
- wherein the beams are connected via connecting ribs to an elongated component that is arranged at least in one plane.
A deformation element assembly for vehicles, comprising:
- a deformation element arranged in a body structure between a panel element and an interior material, the deformation element having a lattice structure,
- wherein the lattice structure comprises U-shaped beams arranged apart from one another and connected to each other by connecting ribs to form an elongated component which is arranged at least in one plane, the U-shaped beams having a transverse rib and reinforcement ribs arranged between legs of each of the U-shaped beams.
A method of making a deformation element assembly for vehicles, comprising:
- forming U-shaped beams by arranging a transverse rib and reinforcement ribs transversely between legs of the U-shaped beams,
- arranging the U-shaped beams at a distance from one another,
- connecting the U-shaped beams via connecting ribs to form an elongated lattice element arranged in at least one plane, and
- arranging the lattice element as a deformation element in a body structure of the vehicle between a panel element and an interior material.
