AN AIRBAG DEVICE WITH DIRECTED INFLATION

The present invention relates to an airbag (6) arranged to be inflated by an inflating device (10) and comprising at least two airbag parts (12, 13, 14) which in turn each comprises at least one bonding (15; 16, 18; 17) and at least one airbag aperture (19; 20 23; 22). Each bonding (15; 16, 18; 17) runs towards at least one corresponding airbag aperture (19; 20 23; 22). The airbags parts (12, 13, 14) are attached to each other by means of circumferential bondings (21, 24) such that the airbags part (12, 13, 14) are in fluid connection with each other via said apertures (19; 20 23; 22). Each bonding (15; 16, 18; 17) intersects at least one circumferential bonding (21, 24) at least at one corresponding position (P1, P2, P3, P4). For each two airbag bondings (15, 16; 15, 18; 16, 17; 16, 18) comprised in different airbag parts (12, 13, 14), which airbag bondings (15, 16; 15, 18; 16, 17; 16, 18) are closer to each other than to any other airbag bonding when intersecting a circumferential bonding (21, 24), these airbag bondings (15, 16; 15, 18; 16, 17; 16, 18) are positioned a corresponding certain distance (D1, D2, D3, D4) from each other when intersecting said circumferential bonding (21, 24).
