A support arm having a proximate support arm segment, a distal support arm segment, and a hinge system having a proximate end pivotally connected to the proximate support arm segment at a proximate pivot, and a distal end pivotally connected to the distal support arm segment at a distal pivot. A tensile member having a first end and a second end, has the first end extending into and secured at a termination point on or beyond either the proximate support arm segment or the distal support arm segment, and the second end extending into and secured at a termination point on or beyond either the proximate support arm segment or the distal support arm segment. The tensile member thereby biases one or both of the proximate support arm segment and the distal support arm segment with respect to the hinge system. |
