First Claim
Patent Images
1. A passenger protecting system, comprising:
- a gas generator; and
a gas bag including an envelope portion and a filling channel with a narrow portion which extends along a predefined deployment direction, wherein the narrow portion has a length greater than a width, wherein the system is configured so that inflation gas from the gas generator directly enters the filling channel;
wherein at least part of the envelope portion is inserted into the narrow portion of the filling channel;
wherein the part of the envelope portion that is inserted into the narrow portion of the filling channel is folded into an envelope pack, wherein the envelope pack is formed so that a long axis of the envelope pack is arranged perpendicularly to a width of the gas bag;
wherein the envelope pack is folded together in a middle of the long axis of the envelope pack to form a U-shaped pack that is inserted into the narrow portion of the filling channel.

Abstract
The invention relates a gas bag (5) which is used for a car passenger-protecting system and comprises a gas generator (20) in which at least a part of the envelop of the bag sac is incorporated in the remaining segment of the envelop of the gas bag. The aim of said invention is to obtain a target positioning of said gas bag prior to blowing it. For this purpose, the segment of the envelop (10) forms a narrow filling channel (15) which extends in a predefined discharge direction (70) and can be connected to the gas generator.

23. A method for folding a gas bag, comprising:
-
inserting at least a part of a gas bag envelope of the gas bag into an envelope section of the gas bag envelope; and inserting the part of the gas bag envelope into a narrow portion of a filling channel, wherein the narrow portion has a length greater than a width; wherein the filling channel is party formed by the gas bag envelope; wherein the filling channel extends along a predefined deployment direction; wherein the part of the gas bag envelope that is inserted into the narrow portion of the filling channel is folded together into an envelope pack, wherein the envelope pack is formed so that a long axis of the envelope pack is arranged perpendicularly to a width of the bas bag; wherein the envelope pack is folded in a middle of the long axis of the envelope pack to form a U-shaped pack that is inserted into the narrow portion of the filling channel. - View Dependent Claims (24, 25, 28, 30)

26. A system for protecting passengers of a vehicle, comprising:
-
a gas generator; and an air bag, including a folded section and a filling channel with a narrow portion, wherein the narrow portion has a length greater than a width; wherein the filling channel is adjacent to the gas generator; wherein the folded section is inserted in the narrow portion of the filling channel so that when inflation gas from the gas generator enter the filling channel, gas pressure builds up, expelling the folded section in a predetermined direction; wherein the folded section that is inserted into the narrow portion of the filling channel is formed by a part of the air bag that is folded into an envelope pack, wherein the envelope pack is formed so that a long axis of the envelope pack is arranged perpendicularly to a width of the air bag; wherein the envelope pack is folded together in a middle of the long axis of the envelope pack to form a U-shaped pack that is inserted into the narrow portion of the filling channel. - View Dependent Claims (29)
