Abstract
An air bag has, at the rear end thereof, an opening for introducing an inflator or gas supplied from the inflator. At least a part of the air bag is made of an air permeable cloth. The air permeable cloth is constituted by a woven fabric. Warps and wefts of the woven fabric are bound with a resin.
Claims11
An air bag at least a part of which is made of an air permeable cloth, wherein said air permeable cloth is constituted by a woven fabric with a thread axis, and at least a part of warps and wefts of said woven fabric is bound with a bonding material of at least one of a resin and rubber coated onto the fabric having the warps and wefts in a form of a lattice with a lattice axis so that said warps and wefts are prevented from sliding and slipping by the bonding material in the form of the lattice, said lattice axis and thread axis crossing with each other at an inclined angle of 30-60.degree..
An air bag comprising:
- a front portion of the air bag, and
- a rear portion of the air bag, said rear portion being made of an air permeable woven cloth formed of warps and wefts, and including a bonding material made of at least one of a resin and rubber, said bonding material being coated onto the air permeable woven cloth formed of the warps and wefts in a lattice pattern to have uncoated warp and weft portions inside the lattice pattern without completely covering the warps and wefts of the woven cloth by the bonding material to thereby bond the warps and wefts by the bonding material in the lattice pattern so that the warps and wefts are prevented from sliding and slipping to thereby provide uniform air permeable property at the rear portion.
An air bag comprising:
- a front portion of the air bag, and
- a rear portion of the air bag, said rear portion being made of an air permeable woven cloth formed of warps and wefts, and including a bonding material made of at least one of a resin and rubber, said bonding material being coated onto the air permeable woven cloth in a lattice pattern to have uncoated warp and weft portions inside the lattice pattern without completely covering the warps and wefts of the woven cloth by the bonding material to thereby bond the warps and wefts by the bonding material in the lattice pattern so that the warps and wefts are prevented from sliding and slipping to thereby provide uniform air permeable property at the rear portion, said lattice pattern being formed of lateral sections parallel to and spaced apart from each other and vertical sections parallel to and spaced apart from each other, said lateral and vertical sections crossing each other, each of said lateral and vertical sections being formed of a plurality of coating lines slightly spaced apart from each other.
