1. A diffuser pocket for an airbag, comprising:
- an insertion portion into which at least a tip portion of an inflator, which injects high-pressure gas at the time of a vehicle collision, is inserted; and
a gas discharging portion which guides and discharges the high-pressure gas injected from the inflator to an airbag cushion,wherein the insertion portion includes front and rear insertion surfaces that are folded upward based on a first folding line positioned at a center of the insertion portion, and upper portions of the front and rear insertion surfaces are joined with each other by an attaching means,wherein the gas discharging portion includes front and rear gas discharging surfaces that are folded to one side based on a second folding line positioned at a center of the gas discharging portion, the second folding line forms a right line of the gas discharging portion, and upper portions and left portions of the front and rear gas discharging surfaces are joined with each other by a second attaching means,wherein a third folding line forming a left line of the insertion portion and perpendicular to the first and second folding lines, prior to folding, is provided between the insertion portion and the gas discharging portion, wherein the discharging portion is folded downward based on the third folding line with respect to the insertion portion.

Abstract
A diffuser pocket for an airbag according to the present invention includes: an insertion portion into which a tip portion of an inflator is inserted; and a gas discharging portion which guides and discharges high-pressure gas injected from the inflator to an airbag cushion, in which the insertion portion has front and rear insertion portions in which lower portions are folded and upper portions are sewn, and the gas discharging portion has front and rear gas discharging surfaces in which a left line is folded, and upper portions and left portions are sewed, thereby preventing damage due to high-temperature and high-pressure gas injected from the inflator.

10. A method of manufacturing a diffuser pocket for an airbag, comprising:
-
a cutting process for cutting a single fabric so as to form an insertion portion into which a tip portion of an inflator is inserted, and a gas discharging portion which is disposed at a left side of the insertion portion so as to guide and discharge high-pressure gas injected from the inflator to an airbag cushion; a folding process for folding the gas discharging portion to a bottom side of the insertion portion based on a first folding line that is a left line of the insertion portion, folding front and rear insertion surfaces of the insertion portion upward based on a second folding line that is positioned in a horizontal direction at a center of the insertion portion, and folding front and rear gas discharging surfaces of the gas discharging portion to one side based on a third folding line that is positioned in the horizontal direction at a center of the gas discharging portion, wherein the first folding line is perpendicular to the second and third folding lines, prior to folding; and a sewing process for sewing and joining upper portions of the front and rear insertion surfaces, and upper portions and left portions of the front and rear gas discharging surfaces. - View Dependent Claims (11, 12, 13, 14)
