BACKGROUND
The present disclosure relates to a child restraint, and particularly to a child restraint coupled to a vehicle passenger seat of a vehicle. More particularly, the present disclosure relates to a child restraint coupled to a vehicle passenger seat by a lap belt included in the vehicle passenger seat.
SUMMARY
According to the present disclosure, a juvenile vehicle seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom and arranged to extend upwardly away from the seat bottom.
In illustrative embodiments, the juvenile vehicle seat further includes a belt-guide clip coupled to the seat bottom and arranged to lie in a fixed position relative to the seat bottom. The belt-guide clip is configured to provide means for locating minimizing rotation of the juvenile vehicle seat about an axis of rotation when the juvenile vehicle seat is in a rear-facing position relative to a vehicle passenger seat underlying the juvenile vehicle seat in response to application of an external force to the vehicle passenger seat so that transfer of a resultant force to an occupant of the seat is minimized during and after application of the external force the juvenile vehicle seat.
In illustrative embodiments, the belt-guide clip is coupled to the seat bottom and configured to receive a portion of a vehicle lap belt therein to anchor the seat bottom in an installed position. Placement of the belt-guide clip midway between a front and rear portions of the seat bottom functions to establish a modified axis of rotation of the seat bottom during rebound movement of the seat bottom toward a seat back of a vehicle passenger seat following exposure of the vehicle passenger seat to an external impact.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION
A child restraint 10 in accordance with the present disclosure includes a juvenile seat 12 and belt-guide clip 14A, 14B as shown in FIGS. 1-4. Belt-guide clip 114A is coupled to juvenile seat 12 to engage a lap belt 16 and is configured provide means for establishing a modified axis of rotation 20 about which child restraint 10 rotates about toward a vehicle passenger seat 18 during a rebound portion of an impact event as shown in FIGS. 5-7. A second embodiment of a belt-guide clip 114 in accordance with the present disclosure is shown in FIGS. 8-11. A third embodiment of a belt-guide clip 214 in accordance with the present disclosure is shown in FIGS. 12-15.
Child restraint 10 is support by vehicle passenger seat 18 in a rear-facing orientation as shown in FIG. 1. A child (not shown) restrained by child restraint 10 faces toward a seat back 18A included in vehicle passenger seat 18 when child restraint 10 is in the rear-facing orientation. Lap belt 16 included in vehicle passenger seat 18 interconnects child restraint 10 to a seat bottom 18B included in vehicle passenger seat 18 as shown in FIG. 1. During an impact event (e.g., a front impact to the vehicle), child restraint 10 in the rear-facing orientation first moves away from seat back 18A and shown in FIGS. 5 and 6 and then rebounds and moves in a direction back toward seat back 18B as shown in FIG. 7. Belt-guide clips 14A, 14B of child restraint 10 cooperate with lap belt 16 to limit rebounding movement of child restraint 10 back toward seat back 18B.
Child restraint 10 includes juvenile seat 12 and first and second belt-guide clips 14A, 14B as shown in FIG. 4. One belt-guide clip 14A is coupled to a first side of a seat bottom 22 included in juvenile seat 12 and the other belt-guide clip 14B is coupled to an opposite second side of seat bottom 22 as suggested in FIG. 4. Lap belt 16 is routed upwardly from vehicle passenger seat 18, through first belt-guide clip 14A, through seat bottom 22, through second belt-guide clip 14B, and back to vehicle passenger seat 18. While only lap belt 16 is shown, any other suitable passenger belt or belts may be used.
During the impact event, an external force F1 is applied to the vehicle and transferred to child restraint 10 as suggested in FIG. 5. Belt-guide clips 14A, 14B engage lap belt 16 and cooperate with lap belt 16 to modify movement of child restraint 10 in response to application of external force F1. Movement is modified as a result of belt-guide clips 14A, 14B engaging lap belt 16 to cause rotation of child restraint 10 about modified axis of rotation 20 to be minimized during a rear-facing rebound portion of the impact.
Second belt-guide clip 14B is substantially the same as first belt-guide clip 14A and the description of first belt-guide clip 14A applicable to second belt-guide clip 14B. First belt-guide clip 14A includes first and second retainer tabs 23, 24, fasteners 25, 26, first and second support rails 27, 28, and a cantilevered belt-retainer arm 30 as shown in FIG. 3. First and second retainer tabs 23, 24 are arranged to receive associated fasteners 25, 26 therein to couple belt-guide clip 14A to seat bottom 22 of juvenile vehicle seat 12. First and second support rails 27, 28 are arranged to extend between first and second retainer tabs 23, 24 to form a guide slot 32 therebetween as shown in FIG. 3. Cantilevered belt-retainer arm 30 is arranged to extend from first retainer tab 23 toward second retainer tab 24. Belt-guide clip 14A is configured to receive lap belt 16 between belt-retainer arm 30 and first and second support rails 27, 28 to retain lap belt 16 relative to juvenile vehicle seat 12 so that modified axis of rotation 20 is established during the impact event.
Juvenile seat 12 includes seat bottom 22, a seat back 34, a seat support 36, and a seat lock 38 as shown in FIG. 4. Seat back 34 is arranged to extend upwardly from seat bottom 22. First and second belt-guide clips 14A, 14B are coupled to opposite sides of seat bottom 22. Seat support 36 is arranged to underlie seat bottom 22. Seat lock 38 is configured to vary a tilt angle of juvenile seat 12 relative to seat support 36.
Child restraint 10 moves as suggested in FIGS. 5-7 in response to application of external force F1 from an impact event. Belt-clip guides 14A, 14B are configured to minimize rebounding movement of the child restraint 10 as shown in FIG. 7.
Child restraint 10 is installed on vehicle passenger seat 18 in the rear-facing position in which a child (not shown) seated in child restraint 10 faces toward seat back 18B of vehicle passenger seat 18. Application of external force F1 to vehicle passenger seat 18 and child restraint 10 causes child restraint 10 to first pivot in a first direction 40 (double phantom arrow) away from seat back 18B of vehicle passenger seat 18 as shown in FIG. 5. After child restraint 10 has rotated in first direction 40 away from seat back 18B of vehicle passenger seat 18 in response to application of external force F1, child restraint 10 rebounds by rotating about modified axis of rotation 20 in a second direction 42 (double phantom arrow) toward seat back 18B as shown in FIGS. 6 and 7. Rotation of child restraint 10 in second direction 42 is limited by belt-guide clips 14A, 14B establishing modified axis of rotation 20.
A child restraint 110 in accordance with another embodiment of the present disclosure includes juvenile seat 12 and first and second belt-guide clips 114A, 114B as shown in FIG. 8. One belt-guide clip 114A is coupled to a first side of a seat bottom 22 included in juvenile seat 12 and the other belt-guide clip 114B is coupled to an opposite second side of seat bottom 22 as suggested in FIG. 8.

During the impact event, an external force F1 is applied to the vehicle and transferred to child restraint 110. Belt-guide clips 114A, 114B engage lap belt 16 and cooperate with lap belt 16 to modify movement of child restraint 110 in response to application of external force F1. Movement is modified as a result of belt-guide clips 114A, 114B engaging lap belt 16 to cause rotation of child restraint 110 about modified axis of rotation 20 to be minimized during a rear-facing rebound portion of the impact.
