1. A child restraint comprising: a tiltable juvenile vehicle seat including a lock-pin receiving slot therein,a seat support adapted to be supported by a vehicle seat underlying the seat support and coupled to the tiltable juvenile vehicle seat for pivotable movement relative to the juvenile vehicle seat about a pivot axis between one of an upright arrangement and at least one tilt arrangement, anda seat lock coupled to the tiltable juvenile vehicle seat and to the seat support to selectively block movement of the tiltable juvenile vehicle seat between the upright arrangement and the tilt arrangement,wherein the seat lock includes a seat-motion blocker arranged to move between a retracted position in which the seat lock blocks relative movement between the tiltable juvenile vehicle seat and the seat support and an extended position in which the tiltable juvenile vehicle seat is free to move relative to the seat support, a pivot pin defining the pivot axis, arranged to extend through the seat support, the seat-motion blocker, and the tiltable vehicle seat, and a lock pin arranged to extend through the lock-pin receiving slot of the tiltable juvenile vehicle seat to interconnect the tiltable juvenile vehicle seat and the seat support to cause the seat support to deform in response to application of an external force to the juvenile restraint to cause the tiltable juvenile vehicle seat to rotate about the pivot axis toward the seat support through an angle β to minimize a gap formed between an upper surface of a seat bottom of a passenger vehicle seat and a front bottom edge of the seat lock so that g-forces exerted on a chest of a child restrained by the juvenile restraint are minimized. 2. The child restraint of claim 1, wherein the pivot pin is arranged to extend through a pivot-pin receiving aperture formed in the tiltable juvenile vehicle seat to interconnect the tiltable juvenile vehicle seat and the seat support. 3. The child restraint of claim 2, wherein the pivot pin is located between the front bottom edge of the seat lock and the lock pin. 4. The child restraint of claim 3, wherein the angle β is in a range of about 15 degrees to 20 degrees. 5. The child restraint of claim 4, wherein the angle β about 19 degrees. 6. The child restraint of claim 1, wherein the angle β about 19 degrees. 7. The child restraint of claim 1, wherein the g-forces exerted on the chest of the child are less than about 55 g's when a Federal Motor Vehicle Safety Standard sled pulse of 25 g's is applied to the child restraint. 8. The child restraint of claim 7, wherein the g-forces exerted on the chest of the child are less than about 45 g's when a Federal Motor Vehicle Safety Standard sled pulse of 25 g's is applied to the child restraint. 9. The child restraint of claim 8, wherein the g-forces exerted on the chest of the child are about 45 g's when a Federal Motor Vehicle Safety Standard sled pulse of 25 g's is applied to the child restraint. 10. The child restraint of claim 1, wherein the seat support includes a support foundation, a pivot mount coupled to the support foundation, and a lock mount coupled to the support foundation and spaced apart from the pivot mount toward a seat back of the tiltable juvenile vehicle seat. 11. The child restraint of claim 10, wherein the pivot pin extends through, the pivot mount included in the seat support, and the seat-motion blocker to couple the tiltable juvenile vehicle seat for pivotable movement relative to the seat support. 12. The child restraint of claim 11, wherein the lock pin is coupled to the seat-motion blocker toward the seat back and arranged to be received in the lock mount included in the seat support to block the tiltable juvenile vehicle seat from pivoting about the pivot axis relative to the seat support when the seat-motion blocker is in the retracted position to retain the child restraint in one of the upright arrangement and the at least one tilt arrangement. 13. A child restraint comprising: a tiltable juvenile vehicle seat including a lock-pin receiving slot therein,a seat support adapted to be supported by a vehicle seat underlying the seat support and coupled to the tiltable juvenile vehicle seat for pivotable movement relative to the juvenile vehicle seat about a pivot axis between one of an upright arrangement and at least one tilt arrangement, anda seat lock coupled to the tiltable juvenile vehicle seat and to the seat support to selectively block movement of the tiltable juvenile vehicle seat between the upright arrangement and the tilt arrangement,wherein the seat lock includes a seat-motion blocker arranged to move between a retracted position in which the seat lock blocks relative movement between the tiltable juvenile vehicle seat and the seat support and an extended position in which the tiltable juvenile vehicle seat is free to move relative to the seat support, a pivot pin defining the pivot axis, and a lock pin arranged to extend through the lock-pin receiving slot of the tiltable juvenile vehicle seat to interconnect the tiltable juvenile vehicle seat and the seat support to cause the seat support to deform in response to application of an external force to the juvenile restraint to cause the tiltable juvenile vehicle seat to rotate about the pivot axis toward the seat support through an angle β to minimize a gap formed between an upper surface of a seat bottom of a passenger vehicle seat and a front bottom edge of the seat lock so that g-forces exerted on a chest of a child restrained by the juvenile restraint are minimized,wherein the seat support includes a support foundation, a pivot mount coupled to the support foundation, and a lock mount coupled to the support foundation and spaced apart from the pivot mount towarda seat back of the tiltable juvenile vehicle seat,wherein the pivot pin extends through the tiltable juvenile vehicle seat, the pivot mount included in the seat support, and the seat-motion blocker to couple the tiltable juvenile vehicle seat for pivotable movement relative to the seat support,wherein the lock pin is coupled to the seat-motion blocker toward the seat back and arranged to be received in the lock mount included in the seat support to block the tiltable juvenile vehicle seat from pivoting about the pivot axis relative to the seat support when the seat-motion blocker is in the retracted position to retain the child restraint in one of the upright arrangement and the at least one tilt arrangement,wherein the lock mount of the seat support includes a lock-pin post formed to include a lock-pin channel having a first channel section, a second channel section, and a transfer channel section interconnecting the first and second channel sections, the lock pin is received in one of the first and second channel sections to block relative movement between the tiltable juvenile vehicle seat and the seat support when the seat-motion blocker is in the retracted position, and the lock pin is received in the transfer channel section to allow relative movement between the tiltable juvenile vehicle seat and the seat support when the seat-motion blocker is in the extended position. 14. The child restraint of claim 13, wherein the seat-motion blocker includes a blocker body formed to include a lost-motion pivot pin slot having a first end and a second end spaced apart from the first end, the pivot pin is arranged to extend through the lost-motion pivot pin slot, the pivot pin is located toward the first end of the lost-motion pivot pin slot when the seat-motion blocker is in the retracted position, and the pivot pin is located toward the second end of the lost-motion pivot pin slot when the seat-motion blocker is in the extended position.
