Abstract
This invention concerns a tubular element for a gas pressure vessel of an airbag module, in particular of a vehicle, wherein the tubular element (1) consists of high-strength steel, has a first and a second end (17, 18) and from the first end (17) to the second end (18) the tubular element (1) has an undeformed section (11), a transition section (12) and a tapering section (13) and on the tapering section (13) at least one radially outwardly extending collar (14) is formed, characterized in that the collar (14) is separated from the transition section (12) by a first length section (130) having an outer diameter (A1) smaller than the outer diameter (A2) of the collar (14) and the wall thickness of the collar (14) is greater than the wall thickness of the first length section (130). Furthermore, the invention concerns a gas pressure vessel and a process for manufacturing a tubular element according to the invention (1).
