Abstract

In an aspect, an outlet valve for a crash bag is provided, and includes a peripheral wall defining an inlet and outlet. The peripheral wall is flexible and has an inner face that defines a passage. The peripheral wall has an outer face that is in an air chamber. The valve has an axis between the inlet and outlet. The peripheral wall includes panels each having first and second side edges that extend generally axially. The first side edge from each of the panels is joined to a second side edge of an adjacent panel by a seam. At least one of the seams is a slope-change seam such that a slope of the peripheral wall in a transverse plane changes by more at said slope-change seam than along a portion of the peripheral wall extending between the slope-change seam and a subsequent one of the seams.
