Abstract
Abstract A sewing section for integrally sewing three members (a front cover member 23 covering a front surface of a seat back, a side cover member 24 covering a side of the seat back, and a ball edge 27 clamped between both the cover members 23 and 24) is comprised of a final sewing portion 26 2 for integrally sewing the front and side cover members 23 and 24 and the ball edge 27 at a location nearer a body portion 27 1 of the ball edge 27, and a temporary sewing portion 26 1 for integrally sewing the front cover member 23 and the ball edge 27 at a location farther from the body portion 27 1 of the ball edge 27. When an air bag is expanded, the final sewing portion 26 2 is broken, and the ball edge 27 is separated from the side cover member 24 and moved in unison with the front cover member 23. Thus, when the air bag used upon side collision of a vehicle and mounted within a seat is deployed, the ball edge in the sewing section 26 is prevented from interfering with the air bag.

Claim 1
Independent Claim
94 words
An occupant protecting system comprising: a seat back; a front cover member defining a front surface of said seat back; a side cover member defining a side of said seat back; a ball edge clamped between said front and side cover members; an air bag module disposed within said seat back; and a sewing section, including a temporary sewing portion sewing one of said front cover member and said side cover member to said ball edge, and a final sewing portion sewing said front cover member, said side cover member and said ball edge.
Claim 2
Dependent Claim
94 words
An occupant protecting system comprising: a seat back; a front cover member defining a front surface of said seat back; a side cover member defining a side of said seat back; a ball edge clamped between said front and side cover members; an air bag module disposed within said seat back; and a sewing section, including a temporary sewing portion sewing one of said front cover member and said side cover member to said ball edge, and a final sewing portion sewing said front cover member, said side cover member and said ball edge.
Claim 3
Dependent Claim
72 words
The occupant protecting system of claim 1, wherein said ball edge includes a body portion located on an exterior side of said seat back and a leg portion located at an interior portion of said seat back; and said temporary sewing portion and said final sewing portion are located at said leg portion at first and second positions, respectively, said first portion being further from said body portion than said second portion.
Claim 4
Dependent Claim
22 words
The occupant protecting system of claim 2, wherein said temporary sewing portion sews only said front cover member to said ball edge.
Claim 5
Dependent Claim
22 words
The occupant protecting system of claim 2, wherein said temporary sewing portion sews only said side cover member to said ball edge.
Claim 6
Dependent Claim
95 words
An occupant protecting system comprising: a seat back including a cover member and a cavity defined inside said cover member by flexible first and second walls, said flexible first wall being more rigid than said flexible second wall; an air bag module including an air bag, located in said cavity within said seat back; wherein said first and second walls meet at a breaking location and are separated during deployment of said air bag to thereby allow deployment of said air bag into a vehicle compartment through the separation of the first and second walls.
Claim 7
Dependent Claim
95 words
An occupant protecting system comprising: a seat back including a cover member and a cavity defined inside said cover member by flexible first and second walls, said flexible first wall being more rigid than said flexible second wall; an air bag module including an air bag, located in said cavity within said seat back; wherein said first and second walls meet at a breaking location and are separated during deployment of said air bag to thereby allow deployment of said air bag into a vehicle compartment through the separation of the first and second walls.
Claim 8
Dependent Claim

The occupant protecting system of claim 5, wherein said first and second walls are made of different materials to thereby achieve the differences in rigidity between the first and second walls.
Claim 12
Dependent Claim
121 words
An occupant protecting system comprising: a seat back including a cavity, a flexible first wall of said cavity being more rigid than a flexible second wall of said cavity; an air bag module including an air bag, located in said cavity within said seat back; wherein said first and second walls meet at a breaking location and are separated during deployment of said air bag to thereby allow deployment of said air bag into a vehicle compartment through the separation of the first and second walls; wherein said seat back includes a side cover member covering a door side of said second wall and said second wall is located nearer to a front of said seat back than said first wall.
Claim 13
Dependent Claim
121 words
An occupant protecting system comprising: a seat back including a cavity, a flexible first wall of said cavity being more rigid than a flexible second wall of said cavity; an air bag module including an air bag, located in said cavity within said seat back; wherein said first and second walls meet at a breaking location and are separated during deployment of said air bag to thereby allow deployment of said air bag into a vehicle compartment through the separation of the first and second walls; wherein said seat back includes a side cover member covering a door side of said second wall and said second wall is located nearer to a front of said seat back than said first wall.
