Claims17
Blind rivet for a screw connection, comprising the following features:
- a. an elastic outer body with a sleeve-shaped shaft which comprises a fastening flange and a hollow cylindrical folding zone which is foldable to an upsetting bulge, so that a support component is supportable between the fastening flange and the upsetting bulge,
- b. a metal bushing which is arranged within the outer body and which comprises a support section arranged in the portion of the folding zone, which is longitudinally displaceable relative to the outer body and is axially limited at an axial end facing away from the support section by a ring-shaped retaining flange which covers a radial expansion of the outer body, and
- c. a fixing sleeve surrounding the outer body, which is arranged adjacent to the retaining flange of the bushing extends axially in the direction of the fastening flange and limits a radial expansion of the outer body outside the folding zone as well as between bushing and fixing sleeve to at most the radial expansion of the retaining flange of the bushing.
