Title: Dynamic displacement energy management device

Abstract: A dynamic energy management restraint anchor device interfaces with a child seat in a vehicle, engaging common child seat attachment clip features. A device restraint anchor is operable to dynamically extract and permit distortion of load bearing deformable member(s) in order to manage the displacement of, and load transferred through, an anchor connected to a child seat. The device may be further operable to limit or prevent restraint anchor displacement and the distortion of said deformable member(s) under quasi-static load conditions in order to meet motor vehicle static load/displacement anchorage performance requirements applicable to certain anchors. Anchor retraction capability and various interlocking configurations for securing the position of an anchor, before or after having extracted, may be incorporated relative to the energy management device interfacing with both a vehicle and a child seat. An indicator may further be provided to identify the functional state of the restraint device.
