Energy-dissipation system

A child restraint comprising

• a juvenile vehicle seat including a seat bottom and a seat back, the seat back including a backrest arranged to extend upwardly away from the seat bottom, a headrest including a rear panel coupled to an upper portion of the backrest, a first side-wing panel coupled to a first side of the rear panel and arranged to extend forwardly away from the rear panel and to lie above the seat bottom, and a second side-wing panel coupled to an opposite second side of the rear panel and arranged to lie in spaced-apart relation to the first side-wing panel to extend forwardly away from the rear panel and to lie above the seat bottom,
• wherein each of the rear, first side-wing, and second side-wing panels and the backrest have an interior surface defining an occupant-receiving space and an oppositely facing exterior surface,
• wherein an energy-dissipation system is coupled to at least a part of the exterior surface of the first and second side-wing panels,
• wherein the backrest includes a third side-wing panel located below and adjacent to the first side-wing panel, a fourth side-wing panel located below and adjacent to the second side-wing panel, and a center panel arranged to interconnect the third and fourth side-wing panels and lie between the seat bottom and the rear panel of the headrest, and the energy-dissipation system is also coupled to at least apart of the exterior surface of the third and fourth side-wing panels,
• wherein the energy-dissipation system includes a first force dissipater coupled to exterior surfaces of the first and third side-wing panels and configured to include a first ride-down pad including at least one crush strip including a series of polygonal structures arranged to extend laterally across companion exterior surface, and a first pad foundation mounted on exterior surfaces and coupled to the first ride-down pad of the first and third side-wing panels and a second force dissipater coupled to exterior surfaces of the second and fourth side-wing panels and configured to include a second ride-down pad including at least one crush strip comprising a series of polygonal structures arranged to extend laterally across companion exterior structures and a second pad foundation mounted on exterior surfaces of the second and fourth side-wing panels and coupled to the second ride-down pad, and
• each polygonal structure is formed to have walls that are arranged to lie generally in perpendicular relation to the exterior surface of an adjacent companion side-wing panel.

• wherein each of the rear, first side-wing, and second side-wing panels and the backrest have an interior surface defining an occupant-receiving space and an oppositely facing exterior surface,
• wherein an energy-dissipation system is coupled to at least a part of the exterior surface of the first and second side-wing panels, and
• wherein the energy-dissipation system includes a first force dissipater having a hollow shell coupled to an exterior surface of the first side-wing panel to form a hollow interior region therebetween and a crush strip cantilevered to an inner surface arranged to face toward the first side-wing panel and arranged to extend inwardly toward the first side-wing panel.
