Patent ID: 8505966

Claim:
An airbag module comprising: an airbag cushion; an inflator for injecting gas into the airbag cushion and inflating the airbag cushion; a housing which houses the airbag cushion before deployment; a partition separating the airbag cushion upon deployment such that the airbag cushion forms a hard chamber and a soft chamber separated by the partition, the partition extending from a lower front of the airbag cushion to an upper rear of the airbag cushion when deployed, the hard chamber supplied with gas by the inflator and positioned in an upper front of the airbag cushion, the soft chamber supplied with gas by the hard chamber via a connecting hole formed in the partition and positioned in a rear of the airbag cushion; and a blocking layer loosely connected to the partition via a tether, the blocking layer disposed on a soft chamber side of the connecting hole when the airbag is deployed, the blocking layer is separated from the connecting hole due to a pressure of gas such that the gas can be transferred from the hard chamber into the soft chamber, and such that when the soft chamber is pressed by a passenger after the airbag cushion is deployed, the blocking layer blocks the connecting hole so that gas is at least temporarily prevented to transfer from the soft chamber into the hard chamber.
