Abstract

A translating rudder pedal system which includes a rudder pedal assembly and a reclinable, translationally movable, seat operably connected to the pedal assembly, with both the pedal assembly and the seat mounted in a vehicle, such as an aircraft. The system ensures that, irrespective of the movement and positioning of the seat, the feet of the user seated in the seat always remain in contact with the control pedals of the rudder pedal assembly.

Claims

1. A translating rudder pedal system mounted in, and operably associated with, an aircraft, comprising:

a. a rudder pedal assembly which includes a pair of rudder control pedals for use by a pilot of said aircraft;

b. means, operably associated with said rudder pedal assembly, for permitting forward and rearward translational movement of said assembly, wherein this means includes a plurality of rails; and

c. means, operably connected to said rudder pedal assembly, for imparting forward and rearward translational motion to said assembly, whereby said assembly is driven forwardly and rearwardly on said plurality of rails by this means, and wherein this means includes;

(1) means, operably connected to said rudder pedal assembly, for converting imparted rotary motion to linear motion, wherein this means includes;

a rotatable jackscrew member to which motion is imparted and which rotates in response to said imparted motion;

a nut member threadedly connected to said jackscrew member, and through which rotates said jackscrew member;

whereby the rotary motion of said jackscrew member is converted by said nut member into linear motion, resulting in linear movement of said nut member, forwardly and rearwardly, in response to the direction of rotational motion of said jackscrew member;

(2) a translational motion imparting source which is operably connected to said means for converting imparted rotary motion to linear motion, and which includes a reclinable, translationally movable, pilot'"'"'s seat;

(3) actuation means operably interconnecting said means for converting imparted rotary motion to linear motion and said translational motion imparting source, wherein said actuation means includes a flexible shaft member and an actuator member, with said shaft member operably connected at one end to said rotatable jackscrew member and operably connected at another end to said actuator member, and with said actuator member attached to said translational motion imparting source; and

(4) a movable bracket member attached to, and interconnecting, said nut member and said rudder pedal assembly, whereby motion imparted to said nut member by said rotating jackscrew member is transmitted by said linearly moving nut member to said movable bracket member, thereby causing said bracket member, and said rudder pedal assembly attached thereto, to move linearly in the same direction as said moving nut member;

whereby when translational motion is imparted to said rudder pedal assembly, said assembly translationally moves in response thereto; and

whereby when said pilot of said aircraft is seated in said seat, said pilot is able to maintain constant feet contact with said pair of rudder control pedals when said seat is still or is translationally moved forwardly or rearwardly, and when said seat is upright, is reclined, or is in transit from, or to, an upright or a reclined position.
