Abstract
A fastening system includes a first fastening element attachable to a structure and which has a base portion for plugging through a structural opening, a second fastening element, and a plastically deformable funnel element. The funnel element has a funnel-like basic shape with a funnel opening. The second fastening element can be introduced through the funnel opening into a receiving opening of the base portion and fastened therein and has a collar which faces away from the receiving opening and which is larger than the funnel opening. The funnel element is designed to be deformed from the funnel-like basic shape into a flat, disk-like final shape by the collar of the second fastening element during the fastening of the second fastening element.
Claims13
A fastening system comprising:
- a first fastening element which is attachable to a structure and which comprises:
- a first collar configured to be fixed against a first side of the structure;
- and
- a base portion configured for plugging through a structural opening toward a second side of the structure opposing the first side;
- a second fastening element comprising a second collar;
- and
- a plastically deformable funnel element, the funnel element having a funnel-like basic shape with a funnel opening;
- wherein the funnel element is configured to be positioned between the second fastening element and the first fastening element to guide the second fastening element to the funnel opening and into a receiving opening of the base portion to be fastened therein;
- wherein the second collar faces away from the receiving opening and is larger than the funnel opening;
- and
- wherein the second collar is configured to rest tightly on the funnel element such that the funnel element is deformed from the funnel-like basic shape into a flat, disk-like final shape by the second collar of the second fastening element during fastening of the second fastening element.
A vehicle comprising a structure and at least one fastening system comprising:
- a first fastening element which is attachable to the structure and which comprises a base portion, the structure having a structural opening into or through which the first fastening element projects;
- a second fastening element comprising a collar;
- and
- a plastically deformable funnel element, the funnel element having a funnel-like basic shape with a funnel opening;
- wherein the funnel element is configured to be positioned between the second fastening element and the first fastening element to guide the second fastening element to the funnel opening and into a receiving opening of the base portion to be fastened therein;
- wherein the collar faces away from the receiving opening and is larger than the funnel opening;
- and
- wherein the second collar is configured to rest tightly on the funnel element such that the funnel element is deformed from the funnel-like basic shape into a flat, disk-like final shape by the collar of the second fastening element during fastening of the second fastening element.
A fastening system comprising:
- a first fastening element which is attachable to a structure and which comprises:
- a first collar configured to be fixed against a first side of the structure;
- and
- a base portion configured for plugging through a structural opening toward a second side of the structure opposing the first side;
- a second fastening element;
- and
- a plastically deformable funnel element, the funnel element having a funnel-like basic shape with a funnel opening;
- wherein the second fastening element is able to be introduced through to the funnel opening and into a receiving opening of the base portion to be fastened therein and has a second collar which faces away from the receiving opening and is larger than the funnel opening;
- the funnel element being configured to be deformed from the funnel-like basic shape into a flat, disk-like final shape by the second collar of the second fastening element during fastening of the second fastening element;
- and
- a spacer with a through-bore, the spacer being able to be positioned between the first fastening element and the funnel element and having a support surface for supporting the funnel element.
