Abstract

A seat system of a vehicle includes a cushion portion configured to support an occupant sitting on the cushion portion, and a back portion configured to support the back of the occupant sitting on the cushion portion. A lower portion includes: a first side; a second side that is opposite the first side; and an infant car seat base located on the first side. An actuator is configured to selectively actuate the lower portion to: a first position where the infant car seat base is located entirely under the cushion portion; and a second position where at least a portion of the second side of the lower portion contacts the cushion portion and the infant car seat base is located entirely above the cushion portion.

2. The seat system of claim 1 wherein the actuator is further configured to an actuator configured to selectively actuate the lower portion to:

a third position where the first side of the lower portion faces upward and the second side of the lower portion faces downward.

3. The seat system of claim 1 further comprising a plurality of anchors,

wherein the lower portion further includes a plurality of latching mechanisms configured to latch to the plurality of anchors.

4. The seat system of claim 3 wherein the plurality of anchors are located between an end of the cushion portion and an end of the back portion.

5. The seat system of claim 1 wherein the actuator includes a plurality of C-shaped brackets that are fixed at first ends to a rotating shaft and are connected at second ends to the lower portion.

6. The seat system of claim 5 wherein the lower portion is configured to rotate about an axis between the second ends between:

when the second side of the lower portion begins to contact the cushion portion; and

when the lower portion reaches the second position.

7. The seat system of claim 6 wherein the actuator further comprises an electric motor that rotates the rotating shaft based on power applied to the electric motor.

8. The seat system of claim 7 further comprising a seat control module configured to selectively apply power to the electric motor based on signals from a user input device of the vehicle.

9. The seat system of claim 8 wherein the seat control module is further configured to selectively apply power to the electric motor based on signals from a mobile device that is separate from the vehicle.

10. The seat system of claim 1 further comprising:

a frame that supports the cushion portion and the back portion; and

a plurality of side members and a back member that, with the lower portion when the lower portion is in the first position, form an empty space under the cushion portion.

11. The seat system of claim 1 further comprising:

a rotatable plate; and

a frame that supports the cushion portion and the back portion and that is held to the rotatable plate.

12. The seat system of claim 11 further comprising a seat control module configured to selectively rotate the rotatable plate based on signals from a user input device of the vehicle.

13. The seat system of claim 12 wherein the seat control module is further configured to selectively rotate the rotatable plate based on signals from a mobile device that is separate from the vehicle.

14. The seat system of claim 11 further comprising:

a first rail that is fixed to the rotatable plate; and

a second rail that is mounted to the frame and that is configured to move along the first rail.

15. The seat system of claim 14 further comprising a seat control module configured to selectively move the second rail based on signals from a user input device of the vehicle.

16. The seat system of claim 15 wherein the seat control module is further configured to selectively move the second rail based on signals from a mobile device that is separate from the vehicle.

17. The seat system of claim 1 wherein the infant car seat base includes a plurality of connection devices that are configured and arranged to connect to a plurality of different types of infant carriers manufactured by different manufacturers.

18. A seat system of a vehicle, comprising:

a cushion portion configured to support an occupant sitting on the cushion portion;

a back portion configured to support the back of the occupant sitting on the cushion portion;
