Abstract

A child restraint includes a juvenile seat and a child-restraint harness coupled to the juvenile seat. A harness mover is coupled to the seat and harness.

First claim

The invention claimed is:

1. A child restraint comprising
a juvenile seat having a seat bottom and a seat back, the seat back including a backrest arranged to extend upwardly from the seat bottom and a headrest mounted for up-and-down movement on the backrest,
a child-restraint harness including a first side belt adapted to wrap over a first shoulder of a child seated on the seat bottom and a second side belt adapted to wrap over a second shoulder of a child seated on the seat bottom, and
a hands-free harness mover coupled to the headrest to move up and down therewith relative to the backrest and to the seat bottom and linked to the first and second side belts, the hands-free harness mover being configured to provide means for automatically holding shoulder-gripping portions of the first and second side belts in a raised position above the seat bottom so that a caregiver can place a child easily on the seat bottom in the juvenile seat under the shoulder-gripping portions without having to use a hand to raise the shoulder-gripping side portions manually upwardly to allow the child to be placed in the juvenile seat and for automatically lowering the shoulder-gripping portions of the first and second side belts toward the seat bottom to lowered positions in response to movement of a child onto the seat bottom so that the shoulder-gripping portions of the first and second side belts are moved relative to the headrest to wrap over the shoulders of the child now seated on the seat bottom and anchor portions of the first and second side belts are arranged to lie between the shoulder-gripping portions and the seat bottom to be mated with a buckle coupled to a free end of the crotch belt.

2. The child restraint of claim 1 , wherein the hands-free harness mover includes a base coupled to the headrest to move up and down therewith relative to the backrest and the seat bottom, a movable actuator flap mounted to the base for movement between a normal forwardly extended position extending away from the headrest and a temporary rearwardly retracted position lying alongside a forward-facing surface of the headrest, and a belt-motion controller configured to provide means for moving the shoulder-gripping portions of the first and second side belts automatically from the raised positions to the lowered positions in response to placement of a child on the seat bottom in the juvenile seat so as to contact the movable actuator flap and cause the movable actuator flap to move from the normal forwardly extended position toward the seat back to the temporary rearwardly retracted position.

3. The child restraint of claim 2 , wherein the belt-motion controller is also configured to provide means for returning the shoulder-gripping portions of the first and second side belts automatically from the lowered positions to the raised positions to separate the shoulder-gripping portions of the first and second side belts from a child seated on the seat bottom so that removal of the child from the seat bottom by a caregiver is possible without first requiring the caregiver first to grasp both side belts and move the shoulder-gripping portions of the side belts upwardly from the lowered positions to the raised positions prior to or during removal of the child from the juvenile seat.

4. The child restraint of claim 1 , wherein the hands-free harness mover includes a base coupled to the headrest to move up and down therewith relative to the backrest and the seat bottom, a movable actuator flap mounted to the base for movement between a normal forwardly extended position and a temporary rearwardly retracted position, a first side-belt position changer coupled at an upper end thereof to the shoulder-gripping portion of the first side belt and at a lower end thereof to the movable actuator flap and a second side-belt position changer coupled at an upper end thereof to the shoulder-gripping portion of the second side belt and at a lower end thereof to the movable actuator flap.

5. The child restraint of claim 4 , wherein the first side-belt position changer is configured to yieldably retain the movable actuator flap in the normal forwardly extended position until a rearwardly directed external child-seating force is applied to the movable actuator flap to cause the movable actuator flap to move to assume the temporary rearwardly retracted position and thereby cause the shoulder-gripping portions of the first and second side belts to move from the raised positions to the lowered positions.

6. The child restraint of claim 4 , wherein the movable actuator flap is mounted on a lower edge of the base for pivotable movement relative to the base about a horizontal actuator-flap pivot axis.

7. The child restraint of claim 6 , wherein the first side-belt position changer includes a first elastic strip associated with and linked to the shoulder-gripping portion of the first side belt, a first webbing having a lower end coupled to a free end of the movable actuator flap and an upper end coupled to an upper tip of the first elastic strip, and several first-webbing retainer clips to couple the first webbing to the first elastic strip to allow for relative movement between the first webbing and the first elastic strip during raising and lowering of the shoulder-gripping portion of the first side belt.

8. The child restraint of claim 7 , wherein the movable actuator flap is mounted on the base to pivot downwardly toward the seat bottom from the normal forwardly extended position to the temporary rearwardly retracted position in response to application of a downward force to the lower end of the first webbing which was transferred by the first webbing to the tip of the first elastic strip so as to cause an upper portion of the first elastic strip that is coupled to the shoulder-gripping portion of the first side belt to curl in a forward and downward direction so that the shoulder-gripping portion of the first side belt is moved from the raised position to the lowered position.

9. The child restraint of claim 4 , wherein the first side-belt position changer includes a first elastic strip associated with and linked to the shoulder-gripping portion of the first side belt, a first webbing having a lower end coupled to a free end of the movable actuator flap and an upper end coupled to an upper tip of the first elastic strip to cause the movable actuator flap normally to move to the raised position, and at least one first webbing retainer clip coupled to the first elastic strip and the first webbing to allow for relative movement of the movable actuator flap and resulting raising and lowering of the shoulder-gripping portion of the first side belt.

10. The child restraint of claim 9 , wherein the movable actuator flap is mounted on a lower edge of the base for pivotable movement relative to the base about a horizontal actuator-flap pivot axis.

11. A child restraint comprising
a juvenile seat having a seat bottom and a seat back arranged to extend upwardly from the seat bottom,
a child-restraint harness including a first side belt adapted to wrap over a first shoulder of a child seated on the seat bottom and a second side belt adapted to wrap over a second shoulder of a child seated on the seat bottom, and
a hands-free harness mover linked to the first and second side belts, the hands-free harness mover being configured to provide means for automatically holding shoulder-gripping portions of the first and second side belts in a raised position above the seat bottom so that a caregiver can place a child easily on the seat bottom in the juvenile seat under the shoulder-gripping portions without having to use a hand to raise the shoulder-gripping side portions manually upwardly to
