Abstract
A an airbag cushion attachment section which may be assembled in the flat condition, and a method of assembling same. The attachment section takes the form of a tubular section having longitudinal ends. One end is attached to the cushion main body. The other end includes fabric loop portions which may be used to secure the cushion to a housing using rods. The tubular mounting section is formed by two fabric pieces, each forming 180.degree. of the tubular mounting section. The two fabric pieces may each have the fabric loops folded over and sewn while the fabric pieces are flat. Thereafter, the two fabric pieces are laid one upon the other, and the lateral edges sewn together while still in the flat condition. The fabric pieces may then be spread apart into the tubular form for assembly to the cushion main body. The sewing in the flat condition permits automated assembly of the attachment section.
