Preferably a seat mounting rail for a passenger aircraft includes a base connected to a crown by a web The crown includes two support flanges protruding laterally in opposite directions from a reinforcement zone that connects to the web and that has a seat-securing groove extending longitudinally therealong Floor panel elements can be supported on the support flanges The reinforcement zone top surface preferably does not protrude above the support flange top surfaces but rather is at least substantially flush and planar therewith The single horizontal base flange forming the base, the single vertical web and the support flanges preferably form a generally I-shaped sectional profile The reinforcement zone may include a triangular sectional hollow lower reinforcement structure tapering to the top of the web Large-area floor panels can span continuously laterally over the rail and can be arranged independently of the spacing between the rails

Flush-top seat mounting rail for passenger aircraft

The present invention provides a stiffening element for stiffening a step-like substructure, in particular in an aircraft or spacecraft, having a foot section which is composed of a fiber composite material and is shaped in the form of a step such that it essentially fills the substructure. A method is also provided for production of a stiffening element for stiffening of a step-like substructure in an aircraft or spacecraft, according to which a profile part with a foot section which is composed of a carbon-fiber-reinforced plastic is provided, at least one layer of a glass-fiber-reinforced plastic is laminated onto the foot section, and the glass-fiber-reinforced plastic is milled corresponding to a step-like shape which essentially fills the substructure.

Stiffening element for an aircraft or spacecraft, and method for its production

A handicapped accessible seat that classifies functionally as an aircraft seat is configured for maneuvering within an aircraft and docking to an aircraft floor using a typical track member having a longitudinal flange like extension and counterbores for mating with a shear plug of an aircraft seat. A bracket or track above the typical track member and containing inwardly-extending longitudinal flanges allows mating association with a plug or plunger on the wheel/caster or bottom seat structure of the handicapped accessible seat ( 94 ). A flange-like extension along the bottom portion of the track, having a planar portion along the floor of the aircraft and an outer, upward portion, could run the entire length of an aircraft or in only specific portions thereof and may also be used to guide the wheels into a locking position.

System and method for integrating handicapped accessible seats into aircraft interior configurations

A seat mounting rail suitable for mounting passenger seats to a floor, for example an aircraft cabin floor, is divided into an upper section for securing a seat and a lower section for mounting the rail to the floor. The upper section is preferably made of a titanium alloy. The lower section is preferably made of an aluminum alloy. Both sections are connected to each other by an interconnection preferably in the form of a metallurgical bond formed under heat and pressure. A bonding metal foil compatible with the metals of which the rail sections are made is used for enhancing the bonding strength of the interconnection.

Seat mounting rail, particularly for a commercial aircraft

The invention relates to devices associated with an interface that is advantageous for the customised attachment of pieces of furniture to the floor of an aircraft. The interface includes rails extending longitudinally in the aircraft cabin, and capable of receiving anchoring devices for connecting the furniture members to said rails. The anchoring devices include axial and radial claw clamping devices which are associated by pairs and manoeuvred by pairs using a same and single lever (58, 95).

Device for attaching a piece of furniture to the floor of an aircraft

A seat mounting rail for securing seats to a floor of a passenger aircraft is made of a seat securing upper section and a rail mounting lower section. Both sections are made of different metals. The upper section is made of a titanium alloy for corrosion protection. The lower rail section is made of an aluminum alloy for weight reduction. The interconnection between the two sections is made as a thermal joint for example formed as a laser weld, which is preferably a butt weld to save welding material.
