Title (EN) SECURING FASTENERS
(FR) ASSUJETTISSEMENT D'ELEMENTS DE FIXATION
Abstract:
(EN) A method of securing a fastener by cold forming into a metal sheet is described. The fastener has a head (1) with an annular recess into which the edges of an aperture in the metal sheet (10) are deformed by cold forming a portion of a shank (4) extending from the head, the shank end (2) remote from the head being provided with a fastening configuration such as a screw thread. The method is especially useful in securing fasteners in deflector caps which serve to hold airbag inflation cylinders in place during inflation as they are able to withstand very high rapidly applied pullout forces.
(FR) L'invention concerne un procédé d'assujettissement d'un élément de fixation dans une tôle, et ce, grâce au formage à froid. L'élément de fixation est doté d'une tête (1) présentant un évidement annulaire dans lequel les bords d'une ouverture ménagée dans la tôle métallique (10) sont déformés par formage à froid d'une partie d'une tige (4) partant de la tête, l'extrémité (2) de cette tige située à distance de la tête étant dotée d'un profil de fixation tel qu'un filet de vis. Ce procédé est particulièrement utile pour l'assujettissement d'éléments de fixation dans des bouchons de déflecteurs servant à maintenir en place des cylindres de gonflage d'airbags en cours de gonflage, vu qu'ils sont susceptibles de résister à des forces d'expulsion appliquées extrêmement rapidement.
