High efficiency, low weight and volume energy absorbent seam |
摘要 |
A parachute canopy seam joint for fastening a ribbon seam and a radial seam of a parachute canopy together. This parachute canopy seam joint combines a ribbon seam using a zigzag stitch pattern and narrow strips of radial tape sewn together with multiple rows of a straight stitch pattern. The ribbon seam attaches two overlapping ribbons within the parachute. The narrow strips of radial tape shroud the ribbon seam which result in a high strength and low weight and volume radial seam and seam joint. This new configuration of a parachute seam joint has distinct advantages in terms of strength and shock absorbing capacity. Specifically, this new parachute seam joint has a seam strength equal to or greater than the minimum rated strength of the adjoining materials and employs a smaller weight and volume of material than conventional radial seams and seam joints.
