Abstract
A stowable cabin attendant seat assembly includes a frame assembly mountable within a wall recess, a backrest mounted for reciprocating vertical translation within the frame assembly, a seat pan mounted for pivoting motion relative to the frame assembly, and at least one link connecting the seat pan to the backrest. The at least one link coordinates the seat pan and backrest motions such that upward lifting motion on the seat pan pushes the backrest vertically up for compact stowing and downward pivoting motion on the seat pan pulls the backrest vertically down.
Claims18
A cabin attendant seat assembly, comprising:
- a frame assembly including spaced frame members disposed in a vertical plane;
- a backrest mounted between the spaced frame members and positioned in the vertical plane for reciprocating vertical translation between the spaced frame members;
- a seat pan mounted between the spaced frame members for pivoting motion, in and out of the vertical plane, relative to the frame assembly;
- first and second links connecting the seat pan to the backrest, each of the first and second links pivotally attached at a first end to the backrest and pivotally attached at a second end to the seat pan such that upward pivoting motion of the seat pan moves the backrest vertically upward within the vertical plane and downward pivoting motion of the seat pan moves the backrest vertically downward within the vertically plane;
- and
- guide tracks formed in the spaced frame members and the backrest carrying guides that travel along the guide tracks, wherein the first end of each of the first and second links is pivotally attached to a respective one of the guides and the guides engage a lower end of the guide tracks to stop pivoting motion of the seat pan in a direction of a deployed position of the seat pan;
- wherein:
- in a stowed position of the cabin attendant seat assembly each of the spaced frame members, the backrest, the seat pan, and the first and second links reside in the vertical plane;
- in the deployed position of the cabin attendant seat assembly the spaced frame members and the backrest reside in the vertical plane, the seat pan resides in a substantially horizontal plane, and the first and second links reside in a plane at an angle to each of the vertical plane and the substantially horizontal plane;
- and
- the seat pan is supported only by the first and second links and pivotal attachment to the spaced frame members.
An assembly adapted to be installed in an aircraft cabin, comprising:
- a wall having a recess defining a vertical plane;
- and
- a cabin attendant seat assembly mounted in the recess, comprising:
- a frame assembly including spaced frame members disposed in the vertical plane;
- a backrest mounted between the spaced frame members and positioned in the vertical plane for reciprocating vertical translation between the spaced frame members;
- a seat pan mounted between the spaced frame members for pivoting motion, in and out of the vertical plane, relative to the frame assembly;
- first and second links connecting the seat pan to the backrest, each of the first and second links pivotally attached at a first end to the backrest and pivotally attached at a second end to the seat pan such that upward pivoting motion of the seat pan moves the backrest vertically upward within the vertical plane and downward pivoting motion of the seat pan moves the backrest vertically downward within the vertically plane;
- and
- guide tracks formed in the spaced frame members and the backrest carrying guides that travel along the guide tracks, wherein the first end of each of the first and second links is pivotally attached to a respective one of the guides and the guides engage a lower end of the guide tracks to stop pivoting motion of the seat pan in a direction of a deployed position of the seat pan;
- wherein:
- in a stowed position of the cabin attendant seat assembly each of the spaced frame members, the backrest, the seat pan, and the first and second links reside in the vertical plane;
- in the deployed position of the cabin attendant seat assembly the spaced frame members and the backrest reside in the vertical plane, the seat pan resides in a substantially horizontal plane, and the first and second links reside in a plane at an angle to each of the vertical plane and the substantially horizontal plane;
- and
- the seat pan is supported only by the first and second links and pivotal attachment to the spaced frame members.
