Taper and flare energy absorption system

An energy absorption system and method comprised of a crush tube (210), a taper component (205), and a flare component (205). The crush tube (210) is inserted into a matching hole in the taper component (205). As the taper and flare components are moved down over the crush tube, the taper component...

Beschreibung
Zusammenfassung:	An energy absorption system and method comprised of a crush tube (210), a taper component (205), and a flare component (205). The crush tube (210) is inserted into a matching hole in the taper component (205). As the taper and flare components are moved down over the crush tube, the taper component decreases the diameter of the crush tube (210) and the flare component (205) splits the crush tube in a plurality of petals (430). The crush tube (210) may include a plurality of initiator slits (215) to aid in the flaring process. When mounted with the longitudinal axis of the crush tube parallel to an axis of an impact, the present invention is capable of absorbing some or all of the crash event by dissipating energy by the tapering, flaring, friction, and other methods.
