Abstract

A modular backrest control includes a mounting bracket, a pivot bracket attached to the mounting bracket, a pivot rod rotatably mounted on the pivot bracket, a lever arm mounted on the pivot rod, and a user actuated lever handle rigidly mounted on the pivot rod. The lever arm is rotatable from a first position to a second position. The lever arm has a connector for attachment to a backrest actuation cable. The user actuated lever handle is rotatable between a lock position and a release position such that rotation of the lever handle from the lock position to the release position causes rotation of the lever arm from a first position to a second position. Characteristically, rotation from the first position to the second position actuates the backrest actuation cable.

First claim

What is claimed is:

1. A modular backrest remote control comprising:
a mounting bracket assembly that includes a mounting bracket, a first side bracket attached to the mounting bracket and a second side bracket attached to the mounting bracket;
a pivot bracket attached to the mounting bracket assembly, the pivot bracket being positioned on the mounting bracket such that the pivot bracket is positioned between the first side bracket and the second side bracket;
a pivot rod rotatably mounted on the pivot bracket;
a lever arm mounted on the pivot rod, the lever arm rotatable from a first position to a second position, the lever arm having a connector for attachment to a backrest actuation cable; and
a user actuated lever handle rigidly mounted on the pivot rod, the user actuated lever handle being rotatable between a lock position and a release position such that rotation of the user actuated lever handle from the lock position to the release position causes rotation of the lever arm from a first position to a second position, wherein rotation from the first position to the second position actuates the backrest actuation cable, the modular backrest remote control being mountable in a vehicle, wherein the first side bracket and the second side bracket each independently defining a first cutout region to allow positioning of the pivot rod and wherein the pivot bracket includes a first lever stop and a second lever stop that limit a range of motion for the lever arm.

2. The modular backrest remote control of claim 1 wherein the pivot bracket is a U-shaped bracket having a first side wall opposing a second side wall, the first side wall and the second side wall connected by a third side wall.

3. The modular backrest remote control of claim 1 further comprising a cover attached to the mounting bracket assembly.

4. The modular backrest remote control of claim 1 further including a biasing spring that biases the user actuated lever handle to the lock position, the biasing spring having a first section attached to the pivot rod and a second section attached to the mounting bracket assembly.

5. The modular backrest remote control of claim 1 wherein the backrest actuation cable includes an inner cable and an outer sheath such that mechanical force is transferred by movement of the inner cable relative to the outer sheath.

6. A modular backrest remote control comprising:
a mounting bracket assembly including a mounting bracket, a first side bracket and a second side bracket, the first side bracket and the second side bracket being attached to the mounting bracket to define a central cavity;
a pivot bracket attached to the mounting bracket and positioned in the central cavity;
a pivot rod rotatably mounted on the pivot bracket;
a lever arm mounted on the pivot rod, the lever arm rotatable from a first position to a second position, the lever arm having a connector for attachment to a backrest actuation cable;
a user actuated lever handle rigidly mounted on the pivot rod, the user actuated lever handle being rotatable between a lock position and a release position; and
a biasing spring that biases the user actuated lever handle to the lock position with a biasing force such that rotation of the user actuated lever handle from the lock position to the release position against the biasing force of the biasing spring causes rotation of the lever arm from a first position to a second position, wherein rotation from the first position to the second position actuates the backrest actuation cable, the modular backrest remote control being mountable in a vehicle wherein the biasing spring has a section attached to the pivot rod and a section attached to the mounting bracket assembly.

7. The modular backrest remote control of claim 6 wherein the pivot bracket is a U-shaped bracket having a first side wall opposing a second side wall, the first side wall and the second side wall connected by a third side wall.

8. The modular backrest remote control of claim 6 further comprising a cover attached to the mounting bracket assembly.

9. The modular backrest remote control of claim 6 wherein the backrest actuation cable includes an inner cable and an outer sheath such that mechanical force is transferred by movement of the inner cable relative to the outer sheath.

10. A method of assembling a vehicle rear seat, the method comprising:
attaching a modular backrest remote control to a seat back;
positioning the seat back with the modular backrest remote control in a vehicle at a vehicle's rear seat location; and
attaching a seat bottom to the vehicle such that a seat bottom support frame is positioned adjacent the modular backrest remote control and below the seat back, wherein the modular backrest remote control includes:
a mounting bracket assembly;
a pivot bracket attached to the mounting bracket assembly;
a pivot rod rotatably mounted on the pivot bracket;
a lever arm mounted on the pivot rod, the lever arm rotatable from a first position to a second position, the lever arm having a connector for attachment to a backrest actuation cable;
a user actuated lever handle rigidly mounted on the pivot rod, the user actuated lever handle being rotatable between a lock position and a release position such that rotation of the user actuated lever handle from the lock position to the release position causes rotation of the lever arm from a first position to a second position, wherein rotation from the first position to the second position actuates the backrest actuation cable; and
a biasing spring that biases the user actuated lever handle to the lock position, the biasing spring having a first section attached to the pivot rod and a second section attached to the mounting bracket assembly.

11. The method of claim 10 wherein the pivot bracket is a U-shaped bracket having a first side wall opposing a second side wall, the first side wall and the second side wall connected by a third side wall.

12. The method of claim 10 wherein the mounting bracket assembly includes a mounting bracket, the pivot bracket being positioned on the mounting bracket.

13. The method of claim 12 wherein the mounting bracket assembly further includes a first side bracket and a second side bracket attached to the mounting bracket wherein the pivot bracket is positioned between the first side bracket and the second side bracket, the first side bracket and the second side bracket each independently defining a first cutout region to allow positioning of the pivot rod.

14. The method of claim 10 wherein the modular backrest remote control further includes a cover attached to the mounting bracket assembly.
