An actuation system for concurrently actuating a first mechanism and a second mechanism from a first state to a second state includes an actuator and a sliding member operatively engaged with the actuator and movable from a first position to a second position in response to actuation of the actuator

An actuation system for concurrently actuating a first mechanism and a second mechanism from a first state to a second state includes an actuator and a sliding member operatively engaged with the actuator and movable from a first position to a second position in response to actuation of the actuator. A connecting member has a relaxed state and a taut state. The connecting member includes a first end coupled to the first mechanism, a second end coupled to the second mechanism, and a medial portion cooperative with the sliding member. Movement of the sliding member from the first position to the second position changes the connecting member from the relaxed state to the taut state, whereby the tension is increased in the connecting member.

1. An actuation system for a folding seat, the seat including a seat frame having a first back support member, a second back support member, a first bottom support member, a second bottom support member, a first seat latch pivotally coupling the first back support member to the first bottom support member about a pivot axis, the first seat latch having a locked position and an unlocked position, and a second seat latch pivotally coupling the second back support member to the second bottom support member about the pivot axis, the second seat latch having a locked position and an unlocked position, the actuation system comprising: an actuator configured for coupling to the seat frame;a housing;a sliding member coupled to the actuator and movable from a first position to a second position within the housing in response to actuation of the actuator; anda connecting member having a first end configured for coupling to the first seat latch, a second end configured for coupling to the second seat latch, and a medial portion cooperative with the sliding member, wherein the connecting member extends without interruption through the sliding member and movement of the sliding member from the first position to the second position increases a path length of the connecting member within the housing and concurrently moves the first seat latch to the unlocked position and the second seat latch to the unlocked position. 2. The actuation system of claim 1, wherein the sliding member is movable to a third position between the first position and the second position, wherein the connecting member is taut with uniform tension at the third position. 3. The actuation system of claim 2, wherein the uniform tension is insufficient to unlock the first latch and the second latch. 4. The actuation system of claim 1, wherein the sliding member is coupled to the actuator by a flexible cable. 5. The actuation system of claim 1, wherein the sliding member includes a surface on which the medial portion of the connecting member is disposed. 6. The actuation system of claim 5, wherein the surface includes a contour at least partially surrounding the medial portion. 7. The actuation system of claim 1, further including a sliding member housing within which the sliding member moves from the first position to the second position. 8. The actuation system of claim 7, wherein the sliding member housing includes a rail, and wherein the sliding member includes a corresponding depression, wherein the rail and depression cooperate during movement from the first position to the second position. 9. The actuation system of claim 1, wherein the actuator is electrically actuated. 10. The actuation system of claim 1, wherein the connecting member is a flexible cable. 11. An actuation system for use with a folding seat, the seat including a seat frame having a first back support member, a second back support member, a first bottom support member, a second bottom support member, a first seat latch pivotally coupling the first back support member to the first bottom support member about a pivot axis, the first seat latch having a locked and unlocked position, and a second seat latch pivotally coupling the second back support member to the second bottom support member about the pivot axis, the second seat latch having a locked and unlocked position, the actuation system comprising: a motor configured for coupling to the seat frame;a single flexible cable having a first end configured for coupling to the first seat latch, a second end configured for coupling to the second seat latch, and a medial portion; anda housing;a sliding member coupled to the motor and configured to interact with the medial portion, the sliding member movable in the housing from a first position to a second position in response to actuation of the motor, wherein movement of the sliding member from the first position to the second position increases the cable length within the housing and concurrently moves the first seat latch to the unlocked position and the second seat latch to the unlocked position. 12. The actuation system of claim 11, wherein the sliding member is movable to a third position between the first position and the second position, wherein the connecting member is taut with uniform tension at the third position. 13. The actuation system of claim 12, wherein the uniform tension is insufficient to unlock the first latch and the second latch.
