Seat central control arm with tensioning

An aircraft seat comprising:

• a lateral tracking system comprising:
• a pawl;
• and
• a lever connected the pawl;
• and
• a control system comprising:
• a central control arm body, wherein the central control arm body has an attachment point and a cable interface feature, wherein the central control arm body has a first portion that is substantially cylindrical and has a cylindrical hole extending along a centerline axis of rotation of the central control arm body and further has an end portion tapered to a collar portion, and wherein the cable interface feature extends outward from the centerline axis of rotation of the central control arm body and has a cable attachment portion;
• a paddle arm hingedly connected, at a first end, to the central control arm body at the attachment point, wherein the paddle arm has a cable attachment point at a second end opposite the first end;
• and
• an adjustment mechanism attached to the central control arm body and extending outward from the centerline axis of rotation of the central control arm body, wherein the adjustment mechanism is aligned longitudinally along the central control arm body with the attachment point, wherein the adjustment mechanism has a set screw extending through the adjustment mechanism substantially perpendicular to the centerline axis of rotation of the central control arm body, wherein the adjustment mechanism further has a threaded end of the set screw closest to the attachment point, and wherein the set screw impinges on a face of the paddle arm;
• a first operating cable attached to the cable interface feature, wherein the first operating cable is operable to apply a rotational force to the central control arm body;
• and
• a second operating cable, wherein the second operating cable is attached on a first end to the paddle arm, and wherein the second operating cable is attached on a second end to the lever of the lateral tracking mechanism;
• and
• wherein the lever is operable move, based on a rotation of the central control arm body, and disengage the pawl and allow the aircraft seat to track in an inboard and outboard direction while the pawl is disengaged.

A control system comprising:

• a central control arm body operable to rotate around a central axis of rotation and to translate a force applied through an attached first operating cable into rotational force about the central axis of rotation;
• a cable interface feature, wherein the cable interface feature is attached to a side of the central control arm body and extends outward from the center of the central control arm body, and wherein the cable interface feature comprises a cable attachment point at an end furthest from the central control arm body, and wherein the first operating cable is attached to the cable attachment point;
• one or more paddle arms, wherein each of the one or more paddle arms are hingedly connected to the central control arm body through an attachment point that allows each of the one or more paddle arms to swing in an arc substantially perpendicular to an axis of rotation of the central control arm body, and wherein each of the one or more paddle arms has a cable attachment point on an end opposite the attachment point to the central control arm body;
• and
• one or more adjustment mechanisms in a one-to-one correspondence with the one or more paddle arms, wherein each of the one or more adjustment mechanisms are aligned longitudinally along the central control arm body with each of the one or more paddle arm attachment points, and wherein each of the one or more adjustment mechanisms features a set screw threaded through the adjustment mechanism substantially perpendicular to the axis of rotation of the central control arm body, wherein a threaded end of the set screw impinges on a curved face of a paddle arm of the one or more paddle arms and is operable to limit a hinged range of motion of the respective paddle are of the one or more paddle arms.
