Airplane seat device
An airplane seat device having at least one backrest, at least one seat component coupled to the backrest and a backrest impact safety device which, by partially decoupling the backrest from the seat component, is provided to at least partly reduce impact forces on the backrest at least in the event of crash. The backrest impact safety device is provided to decouple the backrest from the seat component before the impact forces takes effect.
1. An airplane seat device having at least one backrest, at least one seat component that is coupled to the backrest, and a backrest impact safety device which by way of partial decoupling of the backrest from the seat component is provided for at least partially reducing impact forces on the backrest at least in an event of a crash, wherein
the backrest impact safety device is provided for decoupling the backrest from the seat component prior to the impact forces taking effect,
the backrest impact safety device has at least one inertia module, which is provided for decoupling the backrest impact safety device at least in the event of a crash, and
the backrest impact safety device comprises at least one knuckle joint, which, in a normal operating state, is provided for being coupled to the inertia module.
2. An airplane seat having at least one airplane seat device as claimed in claim 1 .
3. The airplane seat device as claimed in claim 1 , wherein the inertia module is provided for locking the backrest impact safety device at least in the normal operating state.
4. The airplane seat device as claimed in claim 1 , wherein the inertia module is provided for being deflected from a locked position for unlocking the backrest impact safety device in the event of a crash.
5. The airplane seat device as claimed in claim 1 , wherein the inertia module, in the event of a crash, is provided for being deflected from a locked position prior to the impact forces taking effect.
6. The airplane seat device as claimed in claim 1 , wherein at least one additional force element which immediately upon partial decoupling is provided at least for at least temporarily accelerating the backrest.
7. The airplane seat device as claimed in claim 1 , wherein the backrest impact safety device comprises a housing element in which the inertia module is mounted to be axially displaceable.
8. The airplane seat device as claimed in claim 1 , wherein the knuckle joint has at least one form-fitting element, which, in a locked position, is provided for being connected to the inertia module in a form-fitting manner.
9. The airplane seat device as claimed in claim 1 , wherein a housing element has at least one guide element by way of which the inertia module is disposed in the housing element to be axially displaceable.
10. The airplane seat device as claimed in claim 1 , wherein the backrest impact safety device comprises at least one linkage element, which is provided for coupling to the seat component.
11. The airplane seat device as claimed in claim 10 , wherein a housing element has at least one guide element in which the linkage element by way of a first end is fastened to be axially displaceable.
12. The airplane seat device as claimed in claim 10 , wherein the knuckle joint is connected to a housing element and to the linkage element in an articulated manner.
13. The airplane seat device as claimed in claim 10 , wherein the backrest impact safety device has at least one deceleration element, which is provided for absorbing inertia energy of the backrest following a triggering of the backrest impact safety device.
14. An airplane seat device having at least one backrest, at least one seat component that is coupled to the backrest, and a backrest impact safety device, which, by way of partial decoupling of the backrest from the seat component, is provided for at least partially reducing impact forces on the backrest at least in an event of a crash, wherein
the backrest impact safety device is provided for decoupling the backrest from the seat component prior to the impact forces taking effect,
the backrest impact safety device has at least one inertia module, which is provided for decoupling the backrest impact safety device at least in the event of a crash, and
the backrest impact safety device comprises at least one knuckle joint that has at least one form-fitting element which, in a locked position, is provided for being connected to the inertia module in a form-fitting manner.
15. An airplane seat device comprising:
at least one backrest; and
at least one mounting unit, wherein
the at least one backrest is disposed to be pivotable in relation to the mounting unit,
the mounting unit is adapted to mount an aircraft seat, of which the backrest is a part, to a cabin floor,
the airplane seat device has at least one seat component, which is coupled to the backrest, and a backrest impact safety device, which, by way of partial decoupling of the backrest from the seat component, is provided for at least partially reducing impact forces on the backrest at least in an event of a crash,
the backrest impact safety device is provided for decoupling the backrest from the seat component prior to the impact forces taking effect, and
by way of the partial decoupling of the backrest from the seat component, the backrest may rotate about a bearing point, by which the backrest is pivotally mounted.
