Abstract
A gas generator includes a pyrotechnic charge contained in a chamber delimited by a wall and by two transversal walls. At least one of the walls comprises at least one through hole. A covering sheet in the form of a box is located facing the through hole. A seal gasket is provided between the sheet and one of the walls. The seal gasket is positioned between the first tubular part of the covering sheet and the wall for ensuring the seal between the box and the wall towards the through hole.
