Abstract
A safety system for aircraft passenger seats is described. A pallet that can be removably coupled to seats can also be removably coupled to the aircraft floor and one or more brackets, tension fittings, or machined straps that can be coupled to structural beams or components in an aircraft. A keel tension fitting can be attached to a keel beam and then be coupled to the pallet and thereby the seats. By attaching to the keel beam the safety system allows the seating arrangement (pallet and seats) to withstand greater stresses and forces, resulting in increased safety.

-16. (canceled)
A method of securing passenger seats to an aircraft, comprising:
- coupling a pallet to an aircraft floor, the pallet comprising a plurality of receptacles configured to receive one or more passenger seats and further comprising a first attachment means;
- coupling a structural element tension fitting to a first structural element of the aircraft and to an underside of the aircraft floor, the structural element tension fitting configured to extend along an edge where the structural element tension fitting meets the underside of the aircraft floor;
- coupling the structural element tension fitting to the pallet using the first attachment means such that the aircraft floor is sandwiched between the pallet and the structural element tension fitting;
- and
- coupling the one or more passenger seats to the pallet.
2 more elements
A seating system for an aircraft comprising:
- a pallet configured to cover at least a portion of an aircraft floor and comprising;
- one or more attachment mechanisms configured to be coupled to a seat;
- and
- a first one or more holes configured for a first one or more coupling mechanisms;
- a structural element tension fitting comprising;
- one or more horizontal flanges comprising a second one or more holes and configured to be coupled to a bottom side of the aircraft floor by a second one or more coupling mechanisms;
- and
- one or more vertical flanges comprising a third one or more holes and configured to be coupled to a first structural element of the aircraft by a third one or more coupling mechanisms;
- and
- a machine strap comprising;
- at least one horizontal flange comprising a fourth one or more holes and configured to be coupled to at least one of the aircraft floor, the pallet, and the structural element tension fitting by at least one of the first, second, and third one or more coupling mechanisms;
- and
- at least one vertical flange comprising a fifth one or more holes and configured to be coupled to a second structural element of the aircraft by a fourth one or more coupling mechanisms.
