Embodiment Construction

[0033] figure 1Shown is a curtain airbag 100 designed according to the invention, comprising a main chamber 3 and an additional chamber 11 which, in the installed position, is located in front of the main chamber 3 in the direction of travel. The additional chamber 11 is separated from the main chamber 3 by a separation line 13 and is in fluid communication with the main chamber 3 via a flow channel 14 so that the additional chamber 11 expands automatically when the main chamber 3 expands. Partition line 13 is oriented so that, in the installation position of curtain airbag 100 , it runs obliquely upward in the direction of travel when the curtain airbag is inflated.

[0034] Furthermore, at the upper edge 101 a fastening strap 12 is fixed with one end thereof to a first attachment point 15 . The fastening strap 12 is fixed to the additional chamber 11 with its second end at the second attachment point 16 at the lower edge 102 of the curtain airbag 100, and its length is desi...

Abstract

The invention relates to a curtain airbag (100) for a vehicle comprising a main chamber (3) which is shaped in such a way that,in the position being mounted on the vehicle,in the inflated state it covers an inner side structure (10) of the vehicle, wherein the curtain airbag (100) comprises an additional chamber (11) which,in the mounting position,is located on the in driving direction of the vehicle front portion of the main chamber (3), and deploys in the direction of the interior(1)of the vehicle when the curtain airbag is inflated.

Description

technical field [0001] The invention relates to a curtain airbag for a vehicle comprising the features of the preamble of claim 1 . Background technique [0002] The curtain airbag is located in the vehicle on the upper edge of the interior side structure of the vehicle and inflates in the event of an accident in such a way that the curtain airbag covers the interior side structure of the vehicle in the inflated state and thus prevents The occupant directly hits the inner side structure and the occupant is protected from severe injury. [0003] In order to protect passengers, an airbag is further provided in the steering wheel of the vehicle, which is generally designed as a circular airbag and covers the steering wheel in its inflated state. Since the steering wheel is naturally arranged to perform a rotational movement (by virtue of the steering wheel hub not being fixed), the airbag also performs a rotational movement, so the airbag itself needs to be designed symmetrica...
