CONSTITUTION:An air bag 2 is formed of an air bag body 3 and plural laminated reinforcing sheets 4, 4. The reinforcing sheets 4, 4 are laminated and sewed at the inflater fitting opening 6 peripheral edge part of the inner peripheral surface 5 of the air bag body 3. A through hole for inserting a fitting bolt 8 through at the time of assembling the air bag 2 to a bag holder 7 is formed at the peripheral edge part of the inflater fitting opening 6 of the air bag 2. Rubber molded articles 10 are disposed on the inner peripheral surface 11 of the air bag 2. In this case, the rubber molded articles 10 are to be ring bodies of approximately L-shape cross section, and this ring body is formed of an annular base part 12 forming one side of L and an annular wall part 13 forming the other side of L so as to form the outer peripheral edge part of the ring body.

摘要： PURPOSE:To simply and certainly improve strength of an opening part peripheral edge by fastening a ring material with rigidity along the whole periphery on the peripheral edge of the opening part to let gas flow in the inside of an air bag and on the inner peripheral surface side of a retainer. CONSTITUTION:An air bag 1 is devised to open an air bag base material 21 as gas supplied from an inflator 18 is flown in an opening part 12. Additionally, a reinforcing fabric 22 made of the same material as that of the air bag base material 21 is sewn on an opening part peripheral edge 13. Furthermore, a through hole 14 for a bolt 17 to fix the air bag 11 on a bag holder 19 is formed on the opening part peripheral edge 13. In this case, a ring material 15 with rigidity is arranged on the upper surface side inner peripheral edge of the opening part peripheral edge 13, and this is sewn in zigzag chain stitches with a sewing thread 23. Consequently, it is possible to reduce assembling manday an assembling cost respectively as well as simply and certainly improve the strength of the opening part peripheral edge 13.

摘要： PURPOSE:To improve depleted gasoline resistance, cold resistance and ozone- proof performance by providing a diaphragm, one surface of which is gasoline contact surface and the other of which is an air contact surface, wherein the gasoline contact surface is formed by a fluoro rubber layer and the air contact surface is formed by acrylonitrile hydride rubber layer. CONSTITUTION:A rubber layer 3 forming a gasoline contact surface of a foundation 1 is a fluoro rubber (FKM) layer, and a rubber layer 5 forming an air contact surface is an acrylonitrile hydride rubber (hydrofined NBR) layer. In case of assembling this diaphragm in a fuel pump 11 in such a manner that FKM layer 3 is a gasoline contact surface 7a and a hydrofined NBR layer 5 is an air contact surface 7b, excellent gasoline resistance and depleted gasoline resistance are exhibited on the gasoline contact surface 7a side, and excellent cold resistance and ozone-proof performance are exhibited on the air contact surface 7a. Though the embrittlement temperature of FKM is high and cold resistance thereof is not good, FKM is always in contact with gasoline to be a little swollen, so that the embrittlement is lowered. Accordingly, there is no problem in respect of cold resistance in practical application.

摘要： PROBLEM TO BE SOLVED: To provide an air bag that can be stabilized in the opening area and opening timing of a vent hole formed by a tear of tearable portions, in every air bag. SOLUTION: The air bag 10 has in a flexible peripheral wall 11 a slit group 18 of a plurality of slits 19 arranged in an interrupted line. With increasing internal pressure upon an inflow of inflating gas into the air bag 10, the tearable portions 25 between the slits 19 in the peripheral wall 11 are torn to form the vent hole 17 capable of exhausting the inflating gas, in the arrangement position of the slit group 18. A peripheral edge 23 of each slit 19 in the peripheral wall 11 has a melted and solidified portion 24 formed by solidification after melting. COPYRIGHT: (C)2003,JPO
