Air-bag arrangement
First Claim
1. An airbag arrangement in the form of an inflatable curtain, the inflatable curtain comprising an inflatable element, the inflatable element, at one edge, being provided with a gas supply duct associated with a gas generator, mounting elements being provided to mount the inflatable element to the motor vehicle, a front-most mounting element being present on an extension means extending from a forward-roost part of the inflatable element to be connected to a mounting on an “
- A”
-Post of the vehicle, and further mounting means serving to mount at least the gas generator and the associated gas supply duct to the roof line of the motor vehicle, the inflatable element being divided into separate inflatable zones to provide protection for vehicle occupants seated one-behind-the-other, the gas supply duct being connected to inject gas directly into at least one forward-most inflatable zone, the rear-most inflatable zone being connected to the next forward ratable zone by means of a gas flow passage, the gas flow passage communicating with said next forward inflatable zone at a position remote from the gas supply duct.

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.
