Abstract

A vehicle seating assembly includes a seat base, a seatback, and a recliner heart. The recliner heart is rotatably coupled to the seat base and the seatback and the recliner heart is operable between locked and unlocked states. The vehicle seating assembly additionally includes an actuator having a housing defining a housing tab, a motor, a gear operably coupled to the motor where the gear defines a gear tab and a spring tab. The actuator includes an actuator return spring defining a first and second hook where the first hook is coupled to the spring tab. The actuator additionally includes a lever coupled to the gear, a pulley coupled to the gear, a lifting cable coupled between the pulley and the seatback, and a release cable coupled between the lever and the recliner heart. The release cable is configured to transition the recliner heart between the locked and unlocked states.

First claim

What is claimed is:

1. A vehicle seating assembly, comprising:
a seat base;
a seatback;
a recliner heart rotatably coupling the seat base and the seatback, wherein the recliner heart is operable between locked and unlocked states; and
an actuator comprising:
a housing defining a housing tab;
a motor;
a gear operably coupled to the motor, the gear defining a gear tab and a spring tab;
an actuator return spring defining a first hook and a second hook, the first hook coupled to the spring tab;
a lever coupled to the gear;
a pulley coupled to the gear;
a lifting cable coupled between the pulley and the seatback; and
a release cable coupled between the lever and the recliner heart, wherein the release cable is configured to transition the recliner heart between the locked and unlocked states,
wherein the motor is configured to rotate the pulley such that the lifting cable winds around the pulley and moves the seatback from a folded to an unfolded position.

2. The vehicle seating assembly of claim 1 , wherein the motor is a back-drivable motor.

3. The vehicle seating assembly of claim 1 , wherein the actuator return spring is pretensioned.

4. The vehicle seating assembly of claim 1 , wherein the gear is a spur gear.

5. The vehicle seating assembly of claim 1 , wherein the seatback is operable between folded and non-folded configurations.

6. The vehicle seating assembly of claim 5 , wherein the lifting cable is configured to transition the seatback from the folded to the non-folded configuration.

7. The vehicle seating assembly of claim 5 , wherein the motor is configured to drive the gear in at least two directions.

8. A vehicle seating assembly, comprising:
a seat base;
a seatback;
a recliner heart rotatably coupling the seat base and the seatback; and
an actuator comprising:
a motor;
a pulley operably coupled to the motor; and
a lifting cable coupled between the pulley and the seatback,
wherein the motor is configured to rotate the pulley such that the lifting cable winds around the pulley and moves the seatback from a folded to an unfolded position.

9. The vehicle seating assembly of claim 8 , wherein the actuator further comprises:
a gear coupled between the motor and the pulley.

10. The vehicle seating assembly of claim 9 , wherein the actuator further comprises:
an actuator return spring coupled to the gear.

11. The vehicle seating assembly of claim 8 , wherein the motor is a back-drivable motor.

12. The vehicle seating assembly of claim 8 , wherein the actuator further comprises:
a lever operably coupled with the motor; and
a release cable coupled between the lever and the recliner heart, wherein the release cable is configured to transition the recliner heart between locked and unlocked states.

13. A vehicle seating assembly, comprising:
a seat base;
a seatback;

a recliner heart rotatably coupling the seat base and the seatback; and
an actuator comprising:
a motor having an axle extending through a gear wherein the axle is coupled to a reaction pin and the gear is coupled to a lever; and
a release cable coupled between the lever and the recliner heart,

wherein the motor rotates the reaction pin to press against the lever to pull the release cable and transition the recliner heart from a locked to an unlocked state.

14. The vehicle seating assembly of claim 13 , wherein the gear is a spur gear.

15. The vehicle seating assembly of claim 14 , wherein the actuator further comprises:
a pulley coupled to the gear.

16. The vehicle seating assembly of claim 15 , wherein a cable is coupled between the pulley and the seatback.

17. The vehicle seating assembly of claim 16 , wherein the cable is configured to move the seatback from a folded position to an unfolded position.

18. The vehicle seating assembly of claim 17 , wherein the motor is configured to drive the gear in at least two directions.

19. The vehicle seating assembly of claim 18 , wherein the actuator further comprises:
an actuator return spring coupled between the gear and a housing of the actuator.
