What is claimed is: 1. A side airbag apparatus, which deploys airbags between an occupant of a vehicle and a sidewall of said vehicle in order to protect said occupant in the event of side collision of said vehicle, said side airbag apparatus comprising; a first airbag, which is tubular, and one end of said first airbag is fixed at a seat back of a seat of said vehicle and the other end of said first airbag is fixed at a seat cushion of said seat; and a second airbag, which is tubular, and one end of said second airbag is fixed at said seat back and the other end of said second airbag is fixed at an area of said seat proximate said seat cushion; wherein the position of said one end of said second airbag is higher than the position of said one end of said first airbag, and wherein said other end of each of the first and second airbags, respectively, is fixed at substantially the same position on the seat cushion, and wherein a portion of the first airbags overlies a portion of the second airbag, when viewed from the side and when the first airbag and the second airbag are deployed. 2. A side airbag apparatus according to claim 1, further comprising; a first inflator, which generates gas and supplies said gas to said first airbag; and a second inflator, which generates gas and supplies said gas to said second airbag. 3. A side airbag apparatus according to claim 2, wherein the position of said one end of said second airbag is at an upper side portion of said seat back, and the position of said one end of said first airbag is at a mid-height portion of the seat back. 4. A side airbag apparatus according to claim 1, wherein the position of said one end of said second airbag is at an upper side portion of said seat back, and the position of said one end of said first airbag is at a mid-height portion of the seat back. 5. A side airbag apparatus according to claim 1, further comprising; an inflator, which generates gas and supplies said gas to said first airbag and said second airbag; and an adapter which has a first gas outlet and a second gas outlet; wherein said first airbag is connected to said inflator through said first gas outlet, and said second airbag is connected to said inflator through said second gas outlet. 6. A side airbag apparatus according to claim 5, wherein the diameter of said second gas outlet is smaller than said first gas outlet. 7. A side airbag apparatus according to claim 5, wherein the position of said one end of said second airbag is at an upper side portion of said seat back, and the position of said one end of said first airbag is at a mid-height portion of the seat back. 8. A side airbag apparatus according to claim 5, wherein the position of said one end of said second airbag is at an upper side portion of said seat back, and the position of said one end of said first airbag is at a mid-height portion of the seat back such that the position of said one end of said first airbag is vertically spaced apart from the position of said one end of said second airbag. 9. A side airbag apparatus according to claim 1, wherein said second airbag pushes on a flank portion of an occupant when deployed, while the first airbag and said second airbag push on a leg portion of an occupant when deployed. 10. A side airbag apparatus according to claim 1, wherein the position of said one end of said second airbag is at an upper side portion of said seat back, and the position of said one end of said first airbag is at a mid-height portion of the seat back such that the position of said one end of said first airbag is vertically spaced apart from the position of said one end of said second airbag. 11. A side airbag apparatus, which deploys airbags between an occupant of a vehicle and a sidewall of said vehicle in order to protect said occupant in the event of side collision of said vehicle, said side airbag apparatus comprising; a first airbag unit, which has a first airbag, which covers a region ranging from a waist to a leg of said occupant, a first inflator, which generates gas for inflating said first airbag and supplies said gas to said first airbag, and a first module case, which stores said first airbag together with said first inflator therein; and a second airbag unit, which has a second airbag, which covers a region ranging from a shoulder to the leg of said occupant; a second inflator, which generates gas for inflating said second airbag and supplies said gas to said second airbag, and a second module case, which stores said second airbag together with said second inflator therein; wherein said first airbag unit and said second airbag unit are stored in a seat of said vehicle, and wherein a portion of the first airbag overlies a portion of the second airbag when viewed from the side when the first airbag and the second airbag are deployed. 12. A side airbag apparatus according to claim 11, wherein said first airbag and said second airbag respectively, are each formed in the shape of a tube, one end of each of the first and second airbags, respectively, is fixed at a seat back portion of said seat, and the other end of both the first and second airbags is fixed at a fore end of said seat in an area proximate said seat cushion thereof. 13. A side airbag apparatus according to claim 12, wherein the position of said one end of said second airbag is at an upper side portion of said seat back, and the position of said one end of said first airbag is at a mid-height portion of the seat back, and said other end of both the first and second airbags is fixed at substantially the same position on the seat cushion. 14. A side airbag apparatus according to claim 12, wherein said first airbag unit and said second airbag unit are provided near an end of a hinge portion of the seat facing toward a widthwise outside direction of the vehicle, so as to not interfere with the hinge portion, which pivotably connects said seat back with said seat cushion. 15. A side airbag apparatus according to claim 11, wherein said second airbag pushes on a flank portion of an occupant when deployed, while said first airbag and the second airbag push on a leg portion of an occupant when deployed. 16. A side airbag apparatus according to claim 11, wherein the portion of the first airbag which overlies the portion of the second airbag when viewed from the side is deployed at a mid-height location of the seat back. 17. A side airbag apparatus, which deploys airbags between an occupant of a vehicle and a sidewall of said vehicle in order to protect said occupant in the event of a side collision of said vehicle, said side airbag apparatus comprising: a first airbag having a tubular shape, one end thereof being fixed at a seat back of a seat of said vehicle and the other end thereof being fixed at a seat cushion of said seat; a second airbag having a tubular shape, one end thereof being fixed at said seat back, the other end thereof being fixed at an area of said seat proximate said seat cushion, and a position of said one end of said second airbag being higher than a position of said one end of said first airbag; an inflator which generates gas and supplies said gas to said first airbag and said second airbag; and an adaptor having a first gas outlet and a second gas outlet; said first airbag being connected to said inflator through said first gas outlet, and said second airbag being connected to said inflator through said second gas outlet, and the diameter of said second gas outlet being smaller than that of said first gas outlet.
