Abstract
The invention relates to a fastening element for two-dimensional fiber material comprising a basic element and pin-shaped profile elements, which protrude from the basic element in order to penetrate the fiber material. Provision is made for the profile elements to be deformable in order to form retaining heads for the fiber material. The invention further relates to a method for fastening two-dimensional fiber material which can be carried out with a fastening element of such type. By the method in accordance with the invention a cold micro-riveting can be achieved.
Claims9
A fastening element, having a basic element, for riveting a two-dimensional fibre material to the basic element, comprising:
- pin-shaped profile elements protruding from the basic element, each of the pin-shaped profile elements being adapted to penetrate through the fibre material, each of the pin-shaped profile elements of the basic element includes a head portion, each head portion is protruded out of the fiber material, and
- a cover element being adapted to place on and to press against the head portion of the pin-shaped profile elements of the basic element after penetration of the pin-shaped profile elements through the fibre material to cause the head portions of the pin-shaped profile elements of the basic element to deform,
- wherein the head portions of the pin-shaped profile elements of the basic element are deformed by the cover element upon pressured contact with the cover element,
- wherein the deformed head portions are widened into retaining heads and rivets are formed, as the basic element and the cover element are pressed together, and after the retaining heads are formed, the retaining heads are directly attached to an inner side of the cover element facing the basic element, and the retaining heads are located between the cover element and the fibre material, and
- wherein the two-dimensional fibre material being arranged and fastened in a form-locking manner between the basic element and the widened retaining heads.
