1. A personal restraint system for use in a vehicle, the restraint system comprising: a web configured to extend around a portion of an occupant seated in the vehicle;an airbag;a gas tube configured to deliver gas to the airbag; anda fastening system attaching the airbag to the web, wherein the fastening system includes a plurality of curved rows of stitches extending through the airbag and the web, and wherein at least one individual stitch passes through the airbag, the web and the gas tube. 2. The personal restraint system of claim 1 wherein the curved rows define an oval shape having a major axis and a minor axis, and wherein the major axis is at least generally aligned with a longitudinal direction of the web and the minor axis is at least generally perpendicular to the major axis. 3. The personal restraint system of claim 2 wherein the curved rows are concentric oval-shaped rows of stitches. 4. The personal restraint system of claim 1 wherein an angle between any two consecutive stitches is less than approximately 10°. 5. The personal restraint system of claim 1 wherein the fastening system includes a row of stitches forming a spiral. 6. The personal restraint system of claim 1 wherein the curved rows of stitches are continuous with no corners at a periphery of the curved rows of stitches. 7. The personal restraint system of claim 1 wherein the airbag comprises a textile having warp threads oriented at an angle relative to a length of the web. 8. The personal restraint system of claim 7 wherein the angle is between about 0° and 90°. 9. The personal restraint system of claim 1 wherein the airbag comprises a first textile layer having warp threads oriented in a first direction and a second textile layer having warp threads oriented in a second direction different from the first direction. 10. A personal restraint system for use in a vehicle, the restraint system comprising: a web configured to extend around a portion of an occupant seated in the vehicle;an airbag; anda fastening system attaching the airbag to the web, wherein the fastening system includes a plurality of curved rows of stitches extending through the airbag and the web, wherein the curved rows of stitches have an elliptical shape having two foci, and wherein the curved rows of stitches further comprise individual circular stitches at least approximately centered on the individual foci. 11. A method of constructing a vehicle restraint having an airbag, the method comprising: positioning a gas delivery tube within the airbag, the gas delivery tube having at least one gas delivery hole positioned within the airbag;aligning a web of the vehicle restraint with the airbag and the gas delivery tube; andstitching thread through the web, the airbag, and the gas delivery tube in a plurality of curvilinear rows of stitches, wherein at least one individual stitch passes through the web, the airbag and the gas delivery tube. 12.
