1. A child seat configured to be secured to a seat of a vehicle comprising: a seat base secured to the seat of the vehicle;a child receiving portion supported by the seat base;a belt tensioning system incorporated into the seat base for receiving at least one belt that couples the seat base to the seat of the vehicle; anda controller operatively connected to the belt tensioning system and configured to automatically actuate the belt tensioning system,wherein the belt tensioning system is operable in a non-backdriveable state in which belt pay-out is prevented and in a backdriveable state in which belt pay-out is premitted. 2. The child seat of claim 1, wherein the belt tensioning system is configured to drive the belt in a pay-in direction to apply tension to the at least one belt. 3. The child seat of claim 1, wherein the belt tensioning system further comprises at least one drive system, a spindle connected to the belt and rotatable in the pay-in direction or in a payout direction, and a clutch configured to transfer torque generated by the drive system to the spindle to drive the spindle in the pay-in direction. 4. The child seat of claim 3, wherein the at least one drive system comprises one or more electric motors, one or more hydraulic motors, or combinations thereof. 5. The child seat of claim 3, wherein the clutch is configured to transition between an engaged position, in which the clutch is engaged to the spindle allowing the drive system to drive the spindle in the pay-in direction, and a disengaged position, in which the clutch disengages from the spindle, thereby allowing the spindle to rotate free from the drive system in either the pay-in direction or the payout direction. 6. The child seat of claim 5, wherein the belt tensioning system further comprises a clutch motor, the clutch motor being configured to transition the clutch between the engaged position and the disengaged position. 7. The child seat of claim 3, wherein the belt tensioning system further comprises a ratchet and pawl mechanism comprising a pawl configured to selectively engage the spindle to prevent rotation of the spindle in the payout direction. 8. The child seat of claim 7 wherein the belt tensioning system further comprises a manual override mechanism selectively coupled to the pawl that allows a user to manually disengage the pawl from the spindle. 9. The child seat of claim 8, wherein the manual override mechanism comprises an override clutch configured to automatically disengage from the pawl when the child receiving portion is connected to the seat base, thereby preventing the user from manually disengaging the pawl from the spindle with the manual override mechanism when the child receiving portion is connected to the base. 10. The child seat of claim 1, wherein the belt tensioning system comprises a belt retractor configured to apply a preload to the at least one belt prior to application of a full torque of the belt tensioning system. 11. The child seat of claim 1, wherein the child receiving portion comprises a rear-facing infant carrier, a forward facing infant carrier, a forward facing convertible child seat, a rear facing convertible child seat, a combination seat, or a booster seat. 12. The child seat of claim 1, further comprising at least one sensor connected to or associated with the child seat and operatively connected to the controller, wherein the controller is configured to process data from the at least one sensor to determine tension of the belt. 13. The child seat of claim 1, wherein the controller is configured to actuate the belt tensioning system to increase tension of the at least one belt if the tension of the at least one belt is determined to be below a threshold value. 14. The child seat of claim 1, wherein the controller is configured to stop the belt tensioning system if the tension of the at least one belt exceeds a threshold value. 15. The child seat of claim 1, further comprising: a battery for supplying power to the belt tensioning system and controller; anda battery monitor for determining a power level of the battery,wherein the battery monitor is configured to prevent the controller from installing the seat base to the seat of the vehicle when the power level is below a predetermined level. 16. The child seat of claim 1, further comprising at least one user interface device. 17. The child seat of claim 16, wherein the controller is configured to provide installation instructions via the user interface device, and wherein the controller selects a specific installation instruction based on feedback from at least one sensor or a user. 18. The child seat of claim 1, further comprising a leveling system comprising an automated drive system incorporated into the child seat for automatically leveling the child receiving portion relative to the seat of the vehicle. 19. The child seat of claim 18, wherein the leveling system further comprises a manual adjustment mechanism separate from the automated drive system, the manual adjustment mechanism being configured to allow a user to level the child receiving portion without actuating the automated drive system. 20. The child seat of claim 18, wherein the leveling system further comprises a telescoping foot extending from the seat base, and wherein the automated drive system is coupled to the telescoping foot and is configured to retract or extend the telescoping foot to adjust the height of the seat base. 21. The child seat of claim 1, wherein the child receiving portion is releasably connected to the seat base. 22. A method for securing a child to a vehicle seat, the method comprising: providing a child seat comprising: a seat base secured to the seat of the vehicle,a child receiving portion supported by the seat base,at least one sensor,a belt tensioning system incorporated into the seat base for receiving at least one belt that couples the seat base to the seat of the vehicle, anda controller operatively connected to the belt tensioning system and configured to automatically actuate the belt tensioning system; andactuating the belt tensioning system in backdriveable state in which belt pay-out is permitted. 23. The method of claim 22 further comprising providing at least one of installation instructions and installation status via at least one user interface device connected to the child seat.
