Problems solved by technology

[0003] However, previous systems to date only provided support to the upper spinal region and neck region
As a result, this can lead to considerable inclination and deflection of the neck in the direction of the door
[0004] This in turn affects the space available for seat side airbags (SABs), so that they may be limited in their effectiveness

Embodiment Construction

[0027] In FIGS. 1 and 2, in order to better understand the present invention, first use the 50th percentile male crash test dummy (see FIG. 1 ) and / or the 5th percentile female crash test dummy (see FIG. 1 ). Figure 2) shows known curtain airbag technology in the case of a side impact of 30 ms (A) and 50 ms (B).

[0028] The curtain airbag 1 can be seen inflating and supporting the head 2 of the occupant 3 after 30 milliseconds (see A). The spine 4 is straight and the neck 5 is undeflected.

[0029] In addition, the side airbag 6 of the seat is inflated and protects the shoulders 7 and the chest 8 of the occupant.

[0030] However, at 50 milliseconds (see B), the torso 7, 8 (shoulders and chest) tilt towards the side of the collision A due to the force F acting.

[0031] The inclined position of the spine 4 and the deflection of the neck 5 are clearly visible. In addition, the side airbag 6 of the seat is significantly deformed by the intrusion of the shoulder 7 .

Abstract

A side air-curtain-type airbag (10) comprises a gas generator (12) and a main chamber (11) for the head, wherein at least one single chamber (14) for the neck area of an occupant is provided in the main chamber (11).

Description

technical field [0001] The present invention relates to a side curtain airbag comprising a gas generator and a main cavity for the head. Background technique [0002] The use of so-called side curtain airbags (SAC) in motor vehicles is known. In the event of a lateral collision, the curtain airbag extends over the upper lateral vehicle side and in this way cushions the head and / or optionally also the upper torso region of the occupant. Within milliseconds, these curtains unfurl from top to bottom and protect against injury. Furthermore, the penetration of glass shards is prevented, for example. Curtain airbags are accommodated along the roof frame below the headliner, which runs the entire length of the passenger compartment above the window line. According to an embodiment, generally these curtain airbags contain defined protrusions and / or recesses for additional cushioning and to reduce the relative forces between the head and the airbag. [0003] However, previous sys...
