Abstract

Abstract A bag 1 is formed of an occupant-side sheet 2 and a vehicle body-side sheet 3 . These sheets 2, 3 are superposed on each other and joined together along their peripheries so as to form an introduction chamber 7 and a main chamber 8 between the sheets 2 and 3 . A lateral connecting line 10 is connected to the front side of the main chamber 8 and extends rearwardly from the end of the aforementioned edge in the substantially horizontal direction. The rear end of the connecting line 10 is spaced apart from the rear edge of the main chamber 8 . A vertical connecting line 22 extends downwardly from the rear end of the lateral connecting line 10 and the vertical connecting line 21 extend downwardly from a portion of the lateral connecting line 10 . The lower ends of the vertical connecting lines 21, 22 are spaced apart from the lower edge of the main chamber 8 . Cells 8 b , 8 c , 8 d communicate with each other through portions beneath the vertical connecting lines 21, 22.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 215 words
A protective bag for a vehicle occupant's head, comprising: a sheet formed of an occupant side and a vehicle body side and joined together for forming an elongated space therein extending in a longitudinal direction of a vehicle, said space having a gas inlet formed at one end in the longitudinal direction, an introduction chamber communicating with the gas inlet and extending along the longitudinal direction therefrom, and a main chamber communicating with the introduction chamber and having a front side, a rear side, a bottom side and an upper side, a lateral connecting line situated in the main chamber and formed by joining the occupant side and vehicle body side together, said lateral connecting line being directly connected to the front side to extend toward the rear side to form an upper cell between the upper side and the lateral connecting line to thereby introduce a gas from the gas inlet directly toward the rear side through the upper cell, and a first vertical connecting line situated in the main chamber and formed by joining the occupant side and vehicle side, said first vertical connecting line extending downwardly directly from the lateral connecting line to the bottom side to thereby form a rear cell between the rear side and the first vertical connecting line.
Claim 2
Dependent Claim 215 words
A protective bag for a vehicle occupant's head, comprising: a sheet formed of an occupant side and a vehicle body side and joined together for forming an elongated space therein extending in a longitudinal direction of a vehicle, said space having a gas inlet formed at one end in the longitudinal direction, an introduction chamber communicating with the gas inlet and extending along the longitudinal direction therefrom, and a main chamber communicating with the introduction chamber and having a front side, a rear side, a bottom side and an upper side, a lateral connecting line situated in the main chamber and formed by joining the occupant side and vehicle body side together, said lateral connecting line being directly connected to the front side to extend toward the rear side to form an upper cell between the upper side and the lateral connecting line to thereby introduce a gas from the gas inlet directly toward the rear side through the upper cell, and a first vertical connecting line situated in the main chamber and formed by joining the occupant side and vehicle side, said first vertical connecting line extending downwardly directly from the lateral connecting line to the bottom side to thereby form a rear cell between the rear side and the first vertical connecting line.
Claim 3
Dependent Claim 33 words
A protective bag according to claim 1 , wherein said first vertical connecting line has a space relative to the bottom side to allow the gas in the rear cell to flow therethrough.
Claim 4
Dependent Claim 28 words
A protective bag according to claim 2 , wherein said lateral connecting line extends toward the rear side more than a half between the front and rear sides.
Claim 5
Dependent Claim 41 words
A protective bag according to claim 3 , further comprising a second vertical connecting line extending downwardly from the lateral connecting line between the first vertical connecting line and the front side to have a space relative to the bottom side.
Claim 6
Dependent Claim 19 words
A protective bag according to claim 4 , wherein said lateral connecting line is one continuous line without interruption.
Claim 7
Dependent Claim 44 words
