Airbag

Abstract

The invention relates to an airbag, especially a passenger airbag, comprises a rear injection orifice, a front wall (14) for the impact of the occupant as well as two opposed sidewalls (16, 18) and an upper wall and a lower wall. Each of the upper and lower walls is split and consists of side portions (50, 52) which are juxtaposed and are connected to each other along opposite margins (40, 42), wherein the margins (40, 42) of the side portions which are juxtaposed and are connected to each other of the upper wall and / or the lower wall are extended in a nonlinear form. Thus the airbag can be easily and advantageously manufactured and the structure design can be fast adapted to different indoor contour.

Description

technical field [0001] The invention relates to an airbag, especially an airbag for the passenger seat, which comprises a rear inflation port, a front wall for passenger collision, two opposite side walls, an upper wall and a lower wall. Background technique [0002] For the airbags, airbags with different properties are used depending on the size of the interior and the profile of the adjoining surface (in particular of the instrument panel). In the case of very flat surfaces and simple contours, so-called two-dimensional airbags, which can be advantageously produced, should be used. For such airbags, it is possible to manufacture the airbag from a single piece of fabric, in which case the fabric parts are laminated and stitched at the edges adjoined by the lamination. However, as mentioned above, such two-dimensional airbags are more suitable for simpler contours. It is important for the airbag that it rests against and bears on adjacent vehicle components in the event o...

Problems solved by technology

Such three-dimensional airbags are difficult to seam because the edges to be seamed cannot overlap each other via simple folding of the airbag fabric
