1. 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 from the seat bottom and a headrest arranged to lie in spaced-apart relation to the seat bottom to locate portions of the backrest therebetween, and adapted to support a head of a child seated on the seat bottom, and energy-dissipation means coupled to the headrest for dissipating energy associated with movement of the head of a child seated on the seat bottom relative to the headrest following application of external impact forces to the juvenile vehicle seat so that g-loads experienced by the child are minimized, wherein the energy-dissipation means includes a first energy-dissipation finger having a first root end coupled to the headrest and a first tip arranged to lie in spaced-apart relation to the headrest, a second energy-dissipation finger having a second root end coupled to the headrest and a second tip arranged to lie in spaced-apart relation to the headrest, a third energy-dissipation finger having a third root end coupled to the headrest and a third tip arranged to lie in spaced-apart relation to the headrest, and a fourth energy-dissipation finger having a fourth root end coupled to the headrest and a fourth tip arranged to lie in spaced-apart relation to the headrest, the first and second energy-dissipation fingers are arranged to extend upwardly away from the seat bottom to lie in laterally spaced-apart relation to one another and flex rearwardly away from the seat bottom in response to application of a rearwardly directed force to the first and second energy-dissipation fingers during movement of the head of the child seated on the seat bottom, and the third and fourth energy-dissipation fingers are arranged to extend downwardly toward the seat bottom to lie in laterally spaced-apart relation to one another and flex rearwardly away from the seat bottom in response to application of a rearwardly directed forces to the third and fourth energy-dissipation fingers during movement of the head of the child seated on the seat bottom. |
