Aircraft seat control input transfer and disconnect mechanism

Abstract

An aircraft seat includes a seat bottom frame, a seat translation and rotation mechanism attached to the seat bottom frame allowing translation and rotational movement of the seat bottom frame. An armrest is removably attached to the side of the seat bottom frame, and can be set to different positions relative to the seat bottom. The armrest has a seat control mounted to an outside of the armrest, and an input transfer mechanism disposed inside the armrest. The input transfer mechanism has an end engaged to the seat control, and a receiver end. The input transfer mechanism is cable-less. A couple shaft is engaged with the receiver end and engaged with the seat translation and rotation mechanism. When the seat control is actuated, the input transfer mechanism causes the seat translation and rotation mechanism to allow the seat bottom frame to at least one of translate and rotate.

What is claimed is: 
     
         1 . An aircraft seat comprising:
 a seat bottom frame having a side;   a seat translation and rotation mechanism attached to the seat bottom frame allowing at least one of translation and rotational movement of the seat bottom frame;   at least one armrest removably attached to the side of the seat bottom frame, the armrest comprising;
 a seat control mounted to an outside of the armrest; and 
 an input transfer mechanism disposed inside the armrest and having seat control attachment end engaged to the seat control, and a receiver end, wherein the input transfer mechanism is cable-less; and 
   a couple shaft engaged on a first end with the receiver end of the input transfer mechanism and engaged on a second end with the seat translation and rotation mechanism,   wherein when the seat control is actuated, the input transfer mechanism causes the receiver end to rotate, the couple shaft transmits the rotation to the seat translation and rotation mechanism which allows the seat bottom frame to at least one of translate and rotate.   
     
     
         2 . The aircraft seat of  claim 1 , wherein the input transfer mechanism comprises:
 a first control arm having the seat control attachment end and a second end;   a second control arm having a third end and an opposing fourth end, wherein the third end is pivotally engaged with the second end of the first control arm; and   a third control arm having the receiver end and a fifth end pivotally engaged with the fourth end of the second control arm, wherein the fifth end is opposite the receiver end,   wherein when the seat control is actuated, the first, second, and third control arms are at least one of moved or pivoted to rotate the received end.   
     
     
         3 . The aircraft seat of  claim 1 , further comprising:
 at least one armrest bracket disposed on the armrest, wherein the armrest bracket has a plurality of bracket holes;   a seat frame slot in the seat bottom frame configured to receive the armrest bracket, wherein the seat frame slot has a seat frame hole; and   a fastener engaging the armrest bracket and the seat bottom frame by passing consecutively through the seat frame hole and one of the plurality of bracket holes to attach the armrest to the seat bottom frame.   
     
     
         4 . The aircraft seat of  claim 1 , wherein the seat control further comprises:
 a first position allowing only the translational movement; and   a second position allowing only the rotational movement.   
     
     
         5 . The aircraft seat of  claim 1 , further comprising:
 a seat back frame pivotally connected to a back of the seat bottom frame; and   a seat back mechanism disposed in the seat bottom frame;   wherein when the seat control is actuated, the input transfer mechanism causes the receiver end to rotate, the couple shaft transmits the rotation to the seat back mechanism which allows the seat back frame to pivot.   
     
     
         6 . The aircraft seat of  claim 5 , wherein the seat control further comprises a position allowing only the pivoting of the seat back frame. 
     
     
         7 . An aircraft seat armrest comprising:
 at least one armrest bracket disposed on a bottom of the armrest;   a seat control mounted to an outside of the armrest; and   an input transfer mechanism disposed inside the armrest and having seat control attachment end engaged to the seat control, and a receiver end, wherein the input transfer mechanism is cable-less; and   a couple shaft engaged on a first end with the receiver end of the input transfer mechanism and engaged on a second end with a seat translation and rotation mechanism,   wherein when the seat control is actuated, the input transfer mechanism causes the receiver end to rotate, the couple shaft transmits the rotation to the seat back mechanism and the seat translation and rotation mechanism allows the seat bottom frame to at least one of translate and rotate.   
     
     
         8 . An aircraft seat comprising:
 a seat bottom frame having a back and a side;   a seat back frame pivotally connected to the back of the seat bottom frame;   a seat translation and rotation mechanism attached to the bottom frame allowing at least one of translation and rotational movement of the seat bottom frame;   at least one armrest removably attached to the side of the seat bottom frame, the armrest comprising;
 a seat control mounted to an outside of the armrest; and 
 an input transfer mechanism disposed inside the armrest and having seat control attachment end engaged to the seat control, and a receiver end, wherein the input transfer mechanism is cable-less; and 
   a couple shaft engaged on a first end with the receiver end of the input transfer mechanism and engaged on a second end with a seat movement mechanism,   wherein when the seat control is actuated, the input transfer mechanism causes the receiver end to rotate, the couple shaft transmits the rotation to the seat movement mechanism which allows at least one of the seat bottom frame to at least one of translate and rotate and the seat back frame to pivot.
