  • Patent number: 7909362
    Abstract: An airbag cushion is manufactured with a rear fabric panel and two front fabric panels. Each front fabric panel has a projecting tether portion to be sewn to an inner face of the rear fabric panel. The front fabric panels are, firstly, superimposed each other. A back end of the projecting tether portion is sewn to a part of a periphery of the front fabric panel, to form a second stitch portion in a recessed shape. A front end of the tether portion is then sewn to the inner face of the rear fabric panel. A periphery of the rear fabric panel is, in addition, sewn to a periphery of the front fabric panel corresponding to the periphery of the rear fabric panel, to form a third stitch portion.

  • Publication number: 20110042926
    Abstract: The invention relates to a safety arrangement for a vehicle, in particular for a motor vehicle with an airbag (2), folded together in the non-activated basic state, which on a triggering of the safety arrangement (1) by an activation signal is able to be inflated with different volumes in the direction of the interior of the vehicle by means of a gas generator (3), and with a crash sensor system which detects a vehicle impact and emits the activation signal for this. According to the invention, the crash sensor system comprises both a pre-crash sensor system and also an in-crash sensor system, wherein the pre-crash sensor system generally already detects an impending collision before an actual impact, and for this circumstance emits a pre-crash activation signal as activation signal.

  • Patent number: 7857346
    Abstract: A safety arrangement for a motor vehicle is disclosed which comprises an air-bag module (1) having an inflatable air-bag (5) in fluid communication with an inflator (4). An internal tether (14) is provided having a first end (15) and a second end (16). The first end (15) of the tether is connected to a restrainable part (13) of the air-bag, whilst the second end (16) of the tether is free from connection with the air-bag but is initially trapped between the folds or rolls of an initially folded or rolled part of the air-bag. The arrangement is such that, upon inflation of the air-bag, the tether serves to restrain the restrainable part (13) of the air-bag until such time as the folded or rolled part of the air-bag (9) becomes sufficiently unfolded or unrolled to release the second end (16) of the tether (14).
