Abstract
An aircraft seat assembly including first and second stanchions forming interior spaces open through forward slots. A seat pan is pivotally attached to the stanchions and includes rearward extensions that extend through the forward slots and are received in the interior spaces. First and second spring mechanisms reside in the respective first and second interior spaces and are attached at opposing ends to their respective stanchion and to the seat pan. In use, rotating the seat pan toward a deployed position elongates the first and second elongation springs thereby energizing a return force of the spring mechanisms.
Claims15
An aircraft seat assembly, comprising:
- first and second stanchions forming respective first and second interior spaces accessible through respective first and second forward slots;
- a seat pan pivotally attached to the first and second stanchions, the seat pan including first and second rearward extensions that extend through the respective first and second forward slots and are received in the respective first and second interior spaces;
- a seat back attached at one end to the first and second stanchions;
- and
- first and second spring mechanisms that reside in the respective first and second interior spaces, wherein the first spring mechanism includes a first extension spring attached at one end to the first rearward extension and attached at an opposing end to the first stanchion, and the second spring mechanism includes a second extension spring attached at one end to the second rearward extension and attached at an opposing end to the second stanchion;
- wherein movement of the seat pan toward a deployed position of the seat pan elongates the first and second extension springs.
An aircraft seat assembly, comprising:
- first and second stanchions forming respective first and second interior spaces accessible through respective first and second forward slots;
- a seat pan rotationally coupled to the first and second stanchions and configured to rotate between a stowed position and a deployed position, the seat pan including first and second rearward extensions that extend through the respective first and second forward slots and are received in the respective first and second interior spaces;
- and
- first and second springs mechanisms that reside in the respective first and second interior spaces, wherein the first spring mechanism includes a first extension spring attached at one end to the first rearward extension and attached at an opposing end to the first stanchion, and the second spring mechanism includes a second extension spring attached at one end to the second rearward extension and attached at an opposing end to the second stanchion;
- wherein rotation of the seat pan toward the deployed position simultaneously elongates the first and second extension springs.
