Abstract
An elastic link for adjusting the distance between two members, at least one of which is mobile, is characterized in that it includes at least two elastic yarns each attached through one of the opposite ends thereof to two points distant from each other of an intermediate portion of a strap located between the extreme portions of the latter, under conditions such that when a tensile force is applied on said strap, the first elastic yarn is stretched first, the second elastic yarn being then stretched based on the magnitude of the applied tensile force.
Claims12
An elastic link apparatus for permitting an adjustment of a distance between a first element and a second element in which at least one of the elements is mobile, the elastic link apparatus comprising:
- a strap having a length dimension;
- a first elastic strand having one end connecting to a first location along said strap and another end connected to a second location along said strap, said first location being spaced from said second location by a first distance;
- and
- a second elastic strand having one end connected to a third location along said strap and another end connected to a fourth location along said strap, said third location being spaced from said fourth location by a distance less than the distance between said first location and said second location such that when tensile forces are applied to said strap said first elastic strand is stretched first and before the second elastic strand is stretched.
