CUSHIONING MEMBER AND METHOD OF MANUFACTURING THE SAME

摘要

A cushioning member is located between each support frame and the corresponding side of the shutter. The cushioning member (20) includes a pair of belt-shaped base members (21) and pile yarns (22) bridging between the base members (21). Some of the pile yarns (22) are cut at an intermediate portion (23) between the base members (21), which forms opposing first and second cut pile yarns with a cut in between. One of the base members (20) is attached to each support frame, and the other base member (20) contacts the shutter. The cut (23) permits the cushioning member to flexibly respond to movements of the shutter and satisfactorily exerts a cushioning function to suppress swaying of the shutter.
