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.

72. An energy management device, comprising:
-
a retainer having a front wall and a back wall and opposite side walls; an anchor; a connecting member interfacing the anchor; a load-bearing deformable member between the anchor and a movable load-bearing member; a retention member generally parallel to the front and back walls, the retention member in an undeployed state having a lower portion removably inserted in a side wall and an upper surface removably engaged with a portion of a surface of a blocking member; and a downturned portion interfacing the retention member, wherein when sufficient forces pull the connecting member in a direction from the back wall toward the front wall, the movable load-bearing member deforms the deformable member and the lower portion of the retention member becomes removed from the side wall and the upper surface of the retention member is removed from engagement with the surface of the blocking member. - View Dependent Claims (73, 74, 75, 76, 77, 78)

79. An automobile, comprising:
a restraint system including an energy management device, the device including a retainer having a front wall and a back wall and opposite side walls; an anchor; a connecting member interfacing the anchor; a load-bearing deformable member between the anchor and a movable load-bearing member; a retention member generally parallel to the front and back walls, the retention member in an undeployed state having a lower portion removably inserted in a side wall and an upper surface removably engaged with a portion of a surface of a blocking member; and a downturned portion interfacing the retention member, wherein when sufficient forces pull the connecting member in a direction from the back wall toward the front wall, the movable load-bearing member deforms the deformable member and the lower portion of the retention member becomes at least partially removed from the side wall and the upper surface of the retention member is removed from engagement with the surface of the blocking member. - View Dependent Claims (80, 81, 82, 83, 84, 85)

86. A method of absorbing energy via an energy management device having a retainer with a back wall and a front wall, an anchor, a connecting member, a deformable member, movable member, a return assist, a blocking member and a retention member having a portion thereof removably within a recess of a wall of the retainer, the method comprising:
-
when sufficient forces pull the connecting member in a direction from the back wall toward the front wall, deforming the deformable member and removing the retention member at least partially from the recess; and after sufficient forces cause rebounding, returning the movable member in a direction from the front wall toward the back wall. - View Dependent Claims (87, 88, 89)
