Problems solved by technology

However, the problem with such two-dimensional airbags is that the thickness is smaller in the region of its outer peripheral edge, on which the two material layers are sewn, than in the region of its center.
However this leads to increased material costs

Embodiment Construction

[0042] figure 1 and figure 2 Shown is a vehicle seat 20 of a vehicle (not shown) having a seat back 21 and a seat cushion 22, wherein the side air bag device 1 having the air bag 10 and the gas generator is arranged in the seat back 21 . The airbag 10 is in figure 1 and figure 2 is shown in the inflated state and extends from the outer side area of ​​the seat back 21 in the longitudinal direction of the vehicle (x-direction) between the side walls of the passenger compartment of the vehicle and the vehicle occupant on the vehicle seat 20 so as to cover Its shoulder and hip area.

[0043] The airbag 10 consists of a first material layer 11.1 and a second material layer 11.2, the first material layer and the second material layer according to image 3 is produced as a single airbag material layer 11 . If according to figure 1 and figure 2It can be seen that the first material layer 11.1 extends on the side facing away from the vehicle seat 20 in the vehicle longitudin...

Abstract

The invention relates to a side airbag device (1) for vehicles, comprising at least a first and a second material layer (10.1, 10.2) for forming an airbag (10) having at least one chamber (12) that can be inflated by means of gas. In the inflated state of the airbag (10), the first material layer (11.1) extends in a vehicle longitudinal direction (x direction) and the second material layer (11.2) lies opposite the first material layer (11.1). The first and second material layers (11.1, 11.2) are connected to each other along at least a first edge section (11.11, 11.21). According to the invention, in the inflated state of the airbag (10), the first and second material layers (11.1, 11.2) each have a first edge section (11.11, 11.21) extending in a vehicle vertical direction (z direction) and a second edge section (11.12, 11.22) extending in the plane spanned by the vehicle longitudinal direction (x direction) and the vehicle transverse direction (y direction), the first edge sections (11.11, 11.21) of the first and second material layers (11.1, 11.2) are connected by means of a first seam (13) that at least partially bounds the chamber (12), and a second seam (14) is provided, which is formed by the second edge sections (11.12, 11.22) and bounds the chamber (12) additionally to the first seam (13) and extends transversely to the first seam (13).

Description

technical field [0001] The invention relates to a side airbag arrangement for a vehicle according to the preamble of claim 1 . The invention also relates to a method for folding a side airbag arrangement according to the invention. Background technique [0002] In vehicles, in order to protect the vehicle occupants in the event of a side collision or overturn, a side airbag arrangement is provided, the airbag of which is filled with gas generated pyrotechnically by a gas generator. Such side airbag devices are usually deployed from the lateral area of ​​the vehicle seat back or from the side trim of the vehicle, so that the inflated airbag extends in the area between the vehicle occupant, e.g. the driver, and the side wall of the vehicle , thereby protecting the driver's shoulders and waist, possibly also the head. [0003] Such a side airbag arrangement is known, for example, from document DE 10 2012 224 178 A1, the airbag of which is installed in the folded state in the ...
