Abstract

A device may include a support strip disposed adjacent to a lower position of a seatback frame of a passenger seat. A device may include a first cable coupled on a first end to a first strip end of the support strip. A device may include a first cable adjustor coupled to a second end of the first cable, wherein an actuation of the first cable causes a movement of the support strip from a back position to a forward position.

Claims (44)

1 . A system for a passenger seat, comprising:

a support strip configured to be disposed adjacent to a lower position of a seatback frame of the passenger seat;

a first cable coupled on a first end to a first strip end of the support strip, wherein the first cable comprises a Bowden cable, the Bowden cable comprising:

an inner cable coupled to the first cable adjustor and the first end of the support strip; and

an outer cable; and

a first cable adjustor comprising a first knob and coupled to a second end of the first cable via the first knob, wherein the first knob comprises an axle coupled to the inner cable, wherein a rotation of the first knob causes the inner cable to wind onto the axle and causes a movement of the support strip from a back position to a forward position.

2 . The system of claim 1 , wherein the first cable adjustor is integrated into a first armrest of the passenger seat.

3 . The system of claim 2 , further including a first armrest and the seatback frame.

4 . The system of claim 3 , wherein the first cable adjustor is integrated into the first armrest of the passenger seat.

5 . The system of claim 2 , further including the passenger seat.

6 . The system of claim 1 , wherein the first cable adjustor comprises at least one of a lever or pull handle.

7 . The system of claim 1 , further comprising:

a second cable comprising a first end, the first end of the second cable coupled to a second end of the support strip; and

a second cable adjustor coupled to a second end of the second cable, wherein an actuation of the second cable causes a movement of the support strip from a back position to a forward position.

8 . The system of claim 7 , wherein the first cable comprises,

wherein the second cable comprises a second Bowden cable, the second Bowden cable comprising:

an inner cable coupled to the second cable adjustor and the second end of the support strip; and

an outer cable.

9 . A passenger seat comprising:

a seat pan;

a seat back frame;

a first armrest;

a support strip disposed adjacent to a lower position of a seatback frame of the passenger seat;

a first cable coupled on a first end to the support strip, wherein the first cable comprises a Bowden cable, the Bowden cable comprising:

an inner cable coupled to the first cable adjustor and the first end of the support strip; and

an outer cable; and

a first cable adjustor comprising a first knob with axle and integrated into the first armrest, wherein the first knob is coupled to a second end of the first cable, wherein a rotation of the first knob causes the inner cable to wind onto the axle and causes a movement of the support strip from a back position to a forward position.

10 . The passenger seat of claim 9 , further comprising:

a second cable comprising a first end, the first end of the second cable coupled on a first end to a second end of the support strip; and

a second cable adjustor coupled to a second end of the second cable, wherein an actuation of the second cable causes a movement of the support strip from a back position to a forward position.

11 . The passenger seat of claim 10 , wherein the first cable comprises,

wherein the second cable comprises a second Bowden cable, the second Bowden cable comprising:

an inner cable coupled to the second cable adjustor and the second end of the support strip; and

an outer cable.

12 . The passenger seat of claim 11 , wherein the second cable adjustor comprises a second knob, wherein the second knob comprises an axle coupled to the inner cable, wherein the rotation of the second knob causes the inner cable to wind onto the axle and causes a movement of the support strip from a back position to a forward position.

13 . A method comprising:

sitting in a passenger seat wherein the passenger seat comprises:

a support strip disposed adjacent to a lower position of a seatback frame of the passenger seat;

a first cable coupled on a first end to a first strip end of the support strip, wherein the first cable comprises a Bowden cable, the Bowden cable comprising:

an inner cable coupled to the first cable adjustor and the first end of the support strip; and

an outer cable; and

a first cable adjustor comprising a first knob and coupled to a second end of the first cable via the first knob, wherein the first knob comprises an axle coupled to the inner cable, wherein a rotation of the first knob causes the inner cable to wind onto the axle and causes a movement of the support strip from a back position to a forward position;

rotating the knob; and

moving the support strip of the passenger seat from a back position to a forward position.
