Title:
【発明の名称】袋織エアバッグ
Document Type and Number:
Japanese Patent JP3247400
Kind Code:
B2
Abstract:
PURPOSE:To improve the compressive strength at the time of expansion by allowing the boundary between the peripheral part of a hollow part and a joining single texture zone to have the largest length in the warp and weft directions and the smallest length in the bias direction of the double elastic woven air bag and also forming the boundary between the circumscribed circle and inscribed circle thereof along a circular continuous curve defined by a specific equation. CONSTITUTION:The boundary 7 between a double texture forming a hollow part 6 and the peripheral part 4 of a joining single texture zone organized as a single textile is a smooth curve having the shape of a continuous circular arc drawn as a moving trace of an arbitrary point A on the boundary which is at a length L distance from the central part. Circles 8, 9 are concentric with the circle of the radius R having a point C in the hollow part 6 as a center and the length L of a straight line obtained by connecting the point A to the point C is set as L=(1+P/2Xcos4theta), and 0.08<=P<=0.20, wherein R is the average value of the radius of the circumscribed circle and the radius of the inscribed circle, P is the ratio of the difference between the radius of the circumscribed circle and the radius of the inscribed circle to the average radius R, and theta is an angle measured clockwise from the warp direction.
