15. The child restraint of claim 2, wherein a first elastic strip is included in the first side-belt position changer and a second elastic strip is included in the second side-belt position chamber, and the first elastic strip is arranged to apply a lifting force to the shoulder-gripping portion of the first side belt and the second elastic strip is arranged to apply a lifting force to the shoulder-gripping portion of the second side belts to hold the shoulder-gripping portions normally in raised positions above the seat bottom, and wherein the first side-belt position changer further includes a first webbing having a lower end coupled to the rearward end of the actuator strip and an upper end coupled to a distal tip of the first elastic strip included in the first side-belt position changer and retainer clips linking the first webbing to the first elastic strip to allow relative movement therebetween, and the second side-belt position changer further includes a second webbing having a lower end coupled to the rearward end of the actuator strip and an upper end coupled to a distal tip of the second elastic strip included in the second side-belt position changer and retainer clips linking the second webbing to the second elastic strip to allow relative movement therebetween and wherein upward movement of a free end of the crotch belt to mate with latch plates included in the child-restraint harness and coupled to the first and second side belts applies a pulling force to the forward end of the actuator strap and such a pulling force is transferred to the distal tip of the first elastic strip by the first webbing to cause the first elastic strip to curl away from the seat back and toward the base and to the distal tip of the second elastic strip by the second webbing to cause the second elastic strip to curl away from the seat back and toward the base, and wherein the shoulder-gripping portion of the first side belt is pulled downwardly to a lowered position to wrap over a first shoulder of a child seated in the juvenile seat by the curled first elastic strip and the shoulder-gripping portion of the second side belt is pulled downwardly to a lowered position to wrap over a second shoulder of a child seated in the juvenile seat by the curled second elastic strip.
16. The child restraint of claim 14, wherein each of the elastic strips is made of a resilient elastic material that will change from a curled shape to recover a first shape to support the gripping portions of the first and second side belts in the raised positions in response to disengagement of the free end of the crotch belt and the latch plates on the first and second side belts so as to facilitate removal of a child from the juvenile seat by a caregiver.
17. The child restraint of claim 1, wherein the side-belt mover means includes an actuator strap having a forward end coupled to the crotch belt and a rearward end, a first side-belt position changer including an upper portion coupled to the first side belt and a lower portion coupled to the rearward end of the actuator strap, and a second side-belt position changer including an upper portion coupled to the second side belt and a lower portion coupled to the rearward end of the actuator strap, and the first side-belt position changer is configured to hold the first side belt normally in the raised position above the seat bottom and the second side-belt position changer is configured to hold the second side belt normally in the raised position above the seat bottom so that a child can be seated by a caregiver in the juvenile seat on the seat bottom without requiring the caregiver to grasp the first and second belts manually and hold them in the raised positions above the seat bottom.
18. The child restraint of claim 17, wherein the actuator strap is arranged to be moved relative to the seat bottom to apply a pulling force to the first and second side-belt position changers to cause the first and second side-belt position changers to cooperate and move the shoulder-gripping portions of the first and second side belts to lowered positions contacting the shoulders of a child seated in the child-seating space in response to upward movement of a free end of the crotch belt away from the seat bottom toward mating engagement with each of the first and second side belts.
19. The child restraint of claim 18, wherein the side-belt mover means further includes a base coupled to the juvenile seat and the first side-belt position changer includes a first elastic strip coupled to the base and associated with the first side belt of the child-restraint harness and the first elastic strip is arranged normally to hold the first side belt in the raised position.
20. The child restraint of claim 19, wherein the first side-belt position changer further includes a first webbing arranged to extend along the underside of the first elastic strip and coupled to a tip of the first elastic strip to cause a downward force to be applied by the first webbing to the tip of the first elastic strip in response to upward movement of the free end of the crotch belt toward mating engagement with each of the first and second side belts, so that the first side belt is curled to assume a curved shape and wrapped over a shoulder of a child seated in the child-seating space to assume the lowered position.
21. The child restraint of claim 20, wherein the first side-belt position changer further includes several first webbing retainer clips for coupling the first webbing to the topside of the first elastic strip to allow for relative movement between the first webbing and the first elastic strip during raising and lowering of the first side belt.
22. The child restraint of claim 21, wherein the second side-belt position changer includes a second elastic strip coupled to the base and associated with the second side belt, a second webbing extending the underside of the second elastic strip to pass through a second upper slot formed in the base to locate a lower end of the second webbing under the base, and several second webbing retainer clips for coupling the second webbing to the second elastic strip to allow for relative movement between the second webbing and the second elastic strip during raising and lowering of the second side belt.
23. The child restraint of claim 18, wherein the actuator strap is located below the base, the base is formed to include a lower slot and a first upper slot, the crotch belt extends through the lower slot to locate the free end of the crotch belt above the base and a proximal end of the crotch belt below the base, the first webbing extends through the first upper slot to locate an upper end above the base to mate with the tip of the first elastic strip and a lower end below the base to mate with a free rearward end of the actuator strap, and the proximal end of the crotch belt is mated with a forward end of the actuator strap.
