On-vehicle airbag apparatus
First Claim
1. An on-vehicle airbag apparatus comprising:
- an airbag housing having a weakened portion, said weakened portion being breakable;
an airbag stored in a folded state in said airbag housing so that said weakened portion is broken upon inflation;
an inflator for generating gas for inflating the airbag;
a case formed of rigid material hermetically connected to an opening of said airbag and provided with an air discharge port;
a shutter mounted on said case so as to be capable of moving between a closed position in which said air discharge port is closed and an opened position in which said air discharge port is opened; and
a shutter-driving inflator connected to said shutter so as to hold said shutter in the closed position when it is not in use and drive said shutter instantaneously from the closed position to the opened position upon actuation.

Abstract
An on-vehicle airbag apparatus includes an airbag housing having a weakened portion, which is breakable. An airbag is stored in a folded state in the airbag housing so that the weakened portion is broken upon inflation. An inflator for generating gas for inflating the airbag is provided. The speed of response of air discharge from the airbag is sufficiently enhanced. A shutter that can open and close the air discharge port is mounted on a case. The case is formed of rigid material, is hermetically connected to an opening of the airbag and is provided with the air discharge port. A shutter-driving inflator for driving a shutter from the closed position to the opened position when in operation is connected to the shutter.

10. An air discharge mechanism for an on-vehicle airbag apparatus, the on-vehicle airbag apparatus including an airbag housing having a weakened portion, which is breakable, an airbag stored in a folded state in the airbag housing so that the weakened portion is broken upon inflation, and an inflator for generating gas for inflating the airbag, said air discharge mechanism comprising:
-
a case formed of rigid material hermetically connectable to an opening of the airbag and provided with an air discharge port;
a shutter mounted on said case so as to be capable of moving between a closed position in which said air discharge port is closed and an opened position in which said air discharge port is opened; and
a shutter-driving inflator connected to said shutter so as to hold said shutter in the closed position when it is not in use and drive said shutter instantaneously from the closed position to the opened position upon actuation. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A vehicle comprising:
-
a frame;
a seat, said seat being mounted on said frame; and
and airbag apparatus, said airbag apparatus being mounted below said seat and comprising;
an airbag housing having a weakened portion, said weakened portion being breakable;
an airbag stored in a folded state in said airbag housing so that said weakened portion is broken upon inflation;
an inflator for generating gas for inflating the airbag;
a case formed of rigid material hermetically connected to an opening of said airbag and provided with an air discharge port;
a shutter mounted on said case so as to be capable of moving between a closed position in which said air discharge port is closed and an opened position in which said air discharge port is opened; and
a shutter-driving inflator connected to said shutter so as to hold said shutter in the closed position when it is not in use and drive said shutter instantaneously from the closed position to the opened position upon actuation. - View Dependent Claims (18, 19, 20, 21, 22)
