Abstract
An energy-absorbing deformable tube having a first end, a second end, and a reduced portion there between, a proximate tube portion between the reduced portion and the first end and a distal tube portion between the reduced portion and the second end, where a first cross section dimension in the reduced portion is smaller than a corresponding second cross section dimension in the proximal tube portion, distal tube portion, or both, and a cover spanning the reduced portion connected to the proximal tube portion and the distal tube portion, the cover provided over at least a portion of the reduced portion, the distal tube portion or the proximal tube portion or both moves relative to the cover after the deformable tube receives an axial force exceeding a predetermined threshold value.
