<p>A safety harness webbing strap ( 1 ) has a piece of elastomeric belt ( 2 ) stitched ( 3 ) to it at two points along its length. The position of the two stitching along the length of the strap is such that in the relaxed state of the strap, with not tension in either the strap or the belt, the later draws a bight or belly ( 4 ) into the strap. Two lengths ( 5,6 ) of sleeving are stitched into the same points ( 3 ). The elastomeric belt is threaded within the lengths of sleeving. These are of equal length and jointly extend for the full length of the elastomeric belt in its relaxed state. when the elastomeric belt is tensioned, it opens at the joint between the two lengths ( 5,6 ) and stretches to a length greater than the sleeving. Thus it becomes exposed to view between the lengths of sleeving, as shown in <FIGREF IDREF="DRAWINGS">FIG. 2</FIGREF>. The extent of stretching of the belt is limited by the distance along the strap between the stitching. Once the strap is straightened, the belt will stretch no more.</p> |
