US 5873598 AAbstract
1. An air bag device comprising a case having an opening and mounted in a vehicle, an air bag received inside the case in a folded state, an inflator for inflating the air bag to a passenger side disposed at the bottom of the case, and a diffuser for regulating a flow of gas generated by the inflator disposed covering the inflator,wherein the diffuser is provided with a partition wall partitioning a space between the diffuser and the case opening inside the case into a passenger side and a side further from a passenger; a gas guiding passage for guiding gas generated by the inflator to the case opening is formed on the side of the partition wall further from the passenger; the folded air bag is received on the passenger side of the partition wall; and a case-side end portion of an air bag upper part to constitute an upper part of the deployed air bag is disposed covering an exit of the gas guiding passage. 2. An air bag device according to claim 1, wherein a gas delivery opening of the diffuser is disposed at the entrance end of the gas guiding passage.
3. An air bag device according to claim 1, wherein a gas delivery opening of the diffuser is disposed at the exit end of the gas guiding passage.
4. An air bag device according to claim 2 or 3, wherein a gas delivery opening of the diffuser is also provided on the passenger side of the partition wall and the opening area of the gas delivery opening on the side of the partition wall further from the passenger is greater than the opening area of the gas delivery opening on the passenger side of the partition wall.
In this air bag device, preferably, the case is mounted in the vehicle so as to open upward and a folded portion of an air bag lower part to constitute a lower part of the deployed air bag is received in the first receiving part and a folded portion of an air bag upper part to constitute an upper part of the deployed air bag is received in the second receiving part. By this measure,at the time of deployment of the air bag, it is possible to make the air bag upper part inflate early and form a surface for restraining the passenger and then make the air bag lower part inflate rapidly thereafter.
The air bag 3, as shown in FIG. 16A, is a bag sewn in a three-dimensional shape using a cloth made of a synthetic fiber or the like and having a mounting opening 63, and this opening 63 is attached to the inner side of the case opening 21 by means of rivets or the like and an air bag retainer 9. This air bag 3 is folded in a predetermined form and a folded portion of an air bag lower part 33 to constitute a lower part of the deployed air bag is received in the first receiving part 71 and a folded portion of the air bag upper part 32 is received in the second receiving part 72. That is, the air bag 3 is folded so that the upper part 32 and the lower part 33 thereof each form a folded portion, and these folded portions are received in the respective receiving parts 71, 72.
