Abstract
An energy absorber includes a flexible tensile member having lengthwise sections arranged serially along a length of the flexible tensile member. Lengthwise sections define convolutions. Features are provided for both restricting straightening of the convolutions and automatically reconfiguring, in response predetermined tension in the flexible tensile member, to allow straightening of the convolutions.
