  "abstract": "A rivet element for setting a thread into at least one component has a head portion which can be interlockingly brought into abutment with the component and a sleeve portion which can be inserted into an opening extending through the component and can be plastically deformed. The sleeve portion is provided with an internal thread into which a traction mandrel and/or a screw element can be screwed. The sleeve portion has a protruding rib structure on the outer circumference, the rib structure having at least one first support rib and at least one second support rib which extend in the longitudinal direction of the sleeve portion and are separated from one another by a recess. After the plastic deformation of the sleeve portion, the support ribs contact one another in order to allow a direct force flow between the head portion and the sleeve portion.",
  "claims": [
    "1. A rivet element for setting a thread into at least one component, the rivet element comprising: a head portion configured so as to be brought to rest in a form-fitting manner on the component when used; and a sleeve portion which is insertable in use into an opening extending through the component and 1 s plastically deformable, wherein the sleeve portion has an internal thread into which a traction mandrel and/or a screw element is screwable, the sleeve portion has a protruding rib structure on an outer circumference, the rib structure has at least a first support rib and at least a second support rib which extend coaxially in a longitudinal direction of the sleeve portion and which are separated from one another by a recess in the sleeve portion, such that, after plastic deformation of the sleeve portion when used, the first and second support ribs contact one another in order to permit a direct force flow between the head portion and the sleeve portion.",
    "2. The rivet element according to claim 1, wherein the recess is a slot in the sleeve portion.",
    "3. The rivet element according to claim 1, wherein the rib structure has a plurality of rib pairs arranged distributed in the circumferential direction of the sleeve portion, each rib pair has the first support rib and the second support rib which extend in the longitudinal direction of the sleeve portion and which are separated from one another by the recess.",
    "4. The rivet element according to claim 1, wherein the support ribs are cuboidal.",
    "5. The rivet element according to claim 1, wherein the support ribs are formed integrally with and from the same material as the sleeve portion.",
    "6. The rivet element according to claim 1, wherein after the plastic deformation, the sleeve portion has at least one bead portion which is adjacent to the rib structure.",
    "7. The rivet element according to claim 1, wherein the rivet element is made of metal and/or plastics material."

  "description_excerpt": "The invention relates to a rivet element for setting a thread into at least one component, which rivet element has a head portion, which can be brought to rest in a form-fitting manner on the component, and a sleeve portion, which can be inserted into an opening extending through the component and is plastically deformable, wherein the sleeve portion is provided with an internal thread into which a traction mandrel and/or a screw element can be screwed.\n\nA rivet element of the type mentioned at the beginning is used to introduce a load-bearing thread into a thin-walled component, for example a sheet-metal part. The thin-walled component can then be screwed to another component via the thread.\n\nIn the case of components which are accessible from only one side, a so-called blind rivet nut is conventionally used. A blind rivet nut has an elongate, hollow sleeve portion having an internally threaded portion, which is plastically deformable, and a head portion.\n\nFor setting a blind rivet nut, an opening is produced in the component and the rivet element is then inserted into the opening. After the rivet element has been inserted into the opening, the head portion rests on the component and a portion of the sleeve portion extends out of the opening. For the plastic deformation of the sleeve portion, a so-called traction mandrel, which extends through the rivet body and protrudes from the sleeve portion at the head portion, is screwed in.",
