Folienelement

摘要

Foil element for absorbing tensile forces (F) comprises in at least one region at risk of tearing under loading at least one weakened zone (6a) reducing local tension peaks under loading and extending in the contact direction of the tensile forces. The weakened zone is defined on both sides by non-weakened material (7) in at least one direction perpendicular to the contact direction of the tensile forces. Preferred Features: The foil element has at least two foil layers at least partly glued, welded or sealed together. At least one weakened zone is a slit passing through only one foil layer.
