ABSTRACT:
An air-bag arrangement in the form of inflatable curtain (1) has a plurality of inflatable regions (12, 19, 25) spaced from the front of the inflatable curtain to the rear of the inflatable curtain. The rear-most inflatable region (25) is connected by a gas flow passage (23) to the lower-most part of an inflatable chamber (22) forming part of the next forward inflatable region (19) at a point remote from the point where a gas flow duct (8) associated with a gas generator (7) injects gas into that chamber (22). The rear-most inflatable region (25) of the inflatable element does not inflate until after the two forward regions (12, 19) have inflated, and possibly does not open until the region (19) connected to the gas flow passage(23) has been struck by the head of an occupant. An occupant in a rear-most row of seats is normally spaced further from the inflatable curtain than a more forwardly positioned occupant, and thus the rear-most chamber (25) will be inflated before being struck by a rear occupant.
