Abstract
A buckling control assembly for a steering column energy absorption strap assembly is provided. The buckling control assembly includes an inner energy absorption strap operatively coupled to a steering column jacket. Also included is an outer energy absorption strap surrounding at least a portion of the inner energy absorption strap and operatively coupled to the steering column jacket. Further included is a strap constraining structure disposed on a constraint side of the outer energy absorption strap to inhibit buckling of the outer energy absorption strap in a first direction, the outer energy absorption strap having a free side unconstrained to accommodate buckling of the outer energy absorption strap.
