Abstract
A wear resistant attachment for a sit harness or roping harness including a first strap having an enlarged part provided with joining edges which are folded onto the opposite face of a second strap to form wear resistant overlap parts.
Claims6
A method for manufacturing a wear resistant attachment device for a sit harness or a roping harness, comprising:
- positioning a first strap made of flexible synthetic material, having extensions and a laterally enlarged part being bound by edges protruding out with respect to the extensions where the extensions extend beyond the enlarged part, collinearly on a second strap,
- folding the edges towards one another through 180° to come into contact with an opposite face of said second strap, and
- stitching seams along the edges to constitute wear resistant overlap parts protecting opposite edges of the second strap against friction forces.
