Abstract
Abstract An air bag apparatus to be mounted in a vehicle in order to protect an on-board passenger by unfolding and inflating a bag body when the bag body is activated. The air bag apparatus is equipped with an inflator, the bag body which is mounted in folded-up condition in such a way that the gas emitted from the inflator can flow into the bag body and equipped with gas vent holes, and a cover body for covering the bag body in the folded-up condition. Each gas vent hole is fitted with a gas-vent quantity regulating valve capable of decreasing the open quantity of the gas-vent hole during the time the bag body is inflating.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
An air bag apparatus comprising: an inflator for discharging gas; a bag body mounted in folded-up condition so that the gas discharged from said inflator can flow into said bag body; a cover body for covering said bag body in the folded-up condition; wherein said bag body comprises at least one gas vent hole; at least one strap, secured to an inside of said bag body on at least two sides of said at least one gas vent hole; means for temporal tacking which is attached to said at least one strap; wherein said at least one strap is used to decrease an open quantity of said at least one gas vent hole during a time said bag body is inflating; and wherein said means for temporal tacking, at a time during inflation of said bag body, applies a force on said at least one strap in a direction opposite said gas vent hole.
Claim 2
Dependent Claim
154 words
An air bag apparatus comprising: an inflator for discharging gas; a bag body mounted in folded-up condition so that the gas discharged from said inflator can flow into said bag body; a cover body for covering said bag body in the folded-up condition; wherein said bag body comprises at least one gas vent hole; at least one strap, secured to an inside of said bag body on at least two sides of said at least one gas vent hole; means for temporal tacking which is attached to said at least one strap; wherein said at least one strap is used to decrease an open quantity of said at least one gas vent hole during a time said bag body is inflating; and wherein said means for temporal tacking, at a time during inflation of said bag body, applies a force on said at least one strap in a direction opposite said gas vent hole.
Claim 3
Dependent Claim
17 words
The air bag apparatus according to claim 1, wherein said bag body comprises at least two straps.
Claim 4
Dependent Claim
23 words
The air bag apparatus according to claim 1, wherein said means for temporal tacking is medially attached to said at least one strap.
Claim 5
Dependent Claim
26 words
The air bag apparatus according to claim 1, wherein said means for temporal tacking is released by a stretching force of said bag body during inflation.
Claim 6
Dependent Claim
84 words
The air bag apparatus according to claim 1, wherein a relation between a width of said at least one strap and a diameter of said at least one gas vent hole is set so that when an internal pressure of said bag body is increased by the on-board passenger who has pressed against the air bag, a gas-vent throttle passage may be formed as a result of a forcible squeezing of said at least one strap into said at least one gas vent hole.
Claim 7
Dependent Claim
119 words
An air bag to be inflated by a gas discharged from an inflator, comprising: a bag body; at least one gas vent hole; at least one strap secured to an inside of said bag body on at least two sides of said at least one gas vent hole; means for temporal tacking attached to said at least one strap; wherein said at least one strap is used to decrease an open quantity of said at least one gas vent hole during inflation of said bag body; and wherein said means for temporal tacking, at a time during inflation of said bag body, applies a force on said at least one strap in a direction opposite said gas vent hole.
Claim 8
Dependent Claim
119 words
An air bag to be inflated by a gas discharged from an inflator, comprising: a bag body; at least one gas vent hole; at least one strap secured to an inside of said bag body on at least two sides of said at least one gas vent hole; means for temporal tacking attached to said at least one strap; wherein said at least one strap is used to decrease an open quantity of said at least one gas vent hole during inflation of said bag body; and wherein said means for temporal tacking, at a time during inflation of said bag body, applies a force on said at least one strap in a direction opposite said gas vent hole.
Claim 9
Dependent Claim
84 words
The air bag apparatus according to claim 6, wherein a relation between a width of said at least one strap and a diameter of said at least one gas vent hole is set so that when an internal pressure of said bag body is increased by the on-board passenger who has pressed against the air bag, a gas-vent throttle passage may be formed as a result of a forcible squeezing of said at least one strap into said at least one gas vent hole.
Claim 10
Dependent Claim
12 words
The air bag according to claim 6, comprising at least two straps.
Claim 11
Dependent Claim
22 words
The air bag according to claim 6, wherein said means for temporal tacking is medially attached to said at least one strap.
Claim 12
Dependent Claim
31 words
The air bag according to claim 6, wherein said means for temporal tacking is released by a stretching force of said bag body during the time said bag body is inflating.
Claim 13
Dependent Claim
94 words
An air bag to be inflated by a gas discharged from an inflator, comprising: a bag body; at least one gas vent hole; at least two straps, at least one of which is secured to an inside of said bag body on at least two sides of a gas vent hole; a temporal sewing to put at least two of said at least two straps together, wherein at least one of said straps is used to decrease an open quantity of said at least one gas vent hole during inflation of said bag body.
Claim 14
Dependent Claim
94 words
An air bag to be inflated by a gas discharged from an inflator, comprising: a bag body; at least one gas vent hole; at least two straps, at least one of which is secured to an inside of said bag body on at least two sides of a gas vent hole; a temporal sewing to put at least two of said at least two straps together, wherein at least one of said straps is used to decrease an open quantity of said at least one gas vent hole during inflation of said bag body.
Claim 15
Dependent Claim
