Head protective bag
First Claim
1. A head protective bag for passengers located in a vehicle, the bag adapted to be located along an interior side wall of the vehicle and configured to be inflated by gas from an inflator, the bag comprising:
- a cabin side sheet and a window side sheet, wherein the sheets are connected to form an inflatable cell having a single opening for receiving gas from the inflator configured so that when the cell is inflated a bottom edge of the cell extends substantially horizontally along the side wall of the vehicle; and
first and second linear coupling portions located within the inflatable cell and positioned so that when the bag is inflated the linear coupling portions are completely surrounded by inflated portions of the cell; and
wherein the cell includes an upper portion and a lower portion, the upper portion being defined by a half of the cell located closest to a roof of the vehicle when the bag is inflated; and
wherein the linear coupling portions are positioned so that a majority of each linear coupling portion is located in the upper portion of the cell.

Abstract
A head protective bag for vehicle passengers. The bag includes a lower section of which is tightly expanded when the bag is inflated. The protective bag includes an cabin side sheet and a window sheet. The sheets are overlapped and then coupled together along a line to form a main airway and small cells between the sheets. A front portion of the bag is located along an A-pillar of the vehicle in a folded state. An intermediate portion and a rear portion of the bag are located along a roof side rail and a C-pillar in a folded state. If the bag is maximally inflated without being installed in the vehicle, the dimension L from the through hole of a lowermost projection of the front section of the bag to the through hole of a lowermost projection of the rear section of the bag is smaller than the linear distance S from a position at which the lowermost front projection is secured to the A-pillar to a position at which the lowermost rear projection is secured to the C-pillar.
