A passenger seat system for a transportation system includes at least one support structure and at least one seat, which includes a seat frame, which is movable and arrestable on the support structure and has an underside that rests on the support structure and an upper side that receives a seating surface. The seat frame has an arresting device on the underside and an operating unit on the upper side coupled with the arresting device. This is movable into an arresting position and a release position and is blockable at least in the arresting position through a lockable blocking device. The arresting device is adapted for arresting the seat frame on the support structure with the operating unit being in the arresting position and to release it with the operating unit being in the release position.

A blocking mechanism which is integrated with a threaded fastener is proposed for improving the reusability and handling of locking devices for threaded fasteners, such as threaded bolts or nuts. The blocking mechanism can be switched to and from between a blocked state, in which the threaded fastener is gripped in a positively locking manner, and an unblocked state, in which the threaded fastener can be rotated. The blocking mechanism can have a blocking element which can engage into a blocking groove of the threaded fastener in a positively locking manner in the blocked state, and thus prevents rotation. For example, a nut which is provided with the blocking mechanism can be used to pivotably fasten a fastening rod to a fastening rail.

A rotorcraft seating assembly includes a seat base supporting a seat bucket, the seat base having left- and right-side panel portions. Each side panel portion has a linear bucket guide channel set into its inside face (including an upper portion for adjusting the seat bucket relative to the seat base for pilots of varying heights, and a lower portion for energy attenuation (EA) stroking in response to a crash event) and a bucket guide slot set into its outside face (including a linear upper portion corresponding to the range of adjustment of the seat bucket and a curved lower portion allowing the seat bucket to translate forward and away from the seat base during EA stroking). The curved outer bucket guide slot allows for the required EA stroking distance within a minimal vertical space between the seat bucket and the flight deck floor.

The invention provides an in-flight emergency evacuation system in an aircraft which has a seating area comprising of plurality of rows of passenger seats which are positioned on plurality of rails. The passenger seats are slidably movable on the rails. The system further discloses at least one emergency room which is configured to accommodate the passenger seats inside it during an emergency condition for safely ejecting the passengers outside of the emergency rooms. During an emergency condition, the crew members of the aircraft can hit the evacuation button which automatically starts the evacuation process. Once the evacuation button is pressed, the slidably movable motorized passenger seats which are positioned on the rails starts moving in a sequential manner into the emergency room which is capable of accommodating one row of passenger seats at a time and ejecting it outside the aircraft.

A method for joining skin portions of a closed fuselage, in particular for an aircraft or spacecraft, has the following method steps: providing at least a first skin portion and a second skin portion, at least one of the skin portions being fitted with components to remain in the fuselage; positioning at least the first skin portion and the second skin portion relative to one another in a first joint such that the skin portions form a circumferentially closed fuselage arrangement; guiding a first joining head along the first joint on an outer surface of the fuselage arrangement; and guiding a second joining head along the first joint on an inner surface of the fuselage arrangement, the second joining head being guided along longitudinal guide means which are arranged inside the circumferentially closed fuselage arrangement and are formed at least in part by the components to remain in the fuselage.

An aircraft seating module (20) includes a seating mount (26) having a horizontal mounting rail (28) integrally joined to a vertical mounting post (30) at an adjoining elbow (32). The rail (28) includes a mounting boss (34) longitudinally spaced from the post (30) for attachment to an aircraft cabin seat track (18). Both the rail (28) and post (30) include mounting holes (38) for attaching a passenger seat (22) and appended furniture (24) directly to the seating mount (26) and in turn indirectly to the seat track (18) in the cabin floor (12).

Systems for restraining palleted cargo within an aircraft are provided. A first system operates to provide vertical and outboard lateral support to cargo at a location where the opposite ends of the system are connected to surfaces that are aligned at different orientations, for example, one end connected to a horizontal floor and the second end connected to a sidewall of the fuselage of the aircraft. A second system operates to provide aft, vertical, and outboard lateral support to cargo upon a pallet proximate to its corner, and at a location where a portion of cargo extends above a stay out zone of the aircraft.

A vehicle cabin seat rail system includes a seat rail having a top side having a plurality of raster openings and mechanically couplable with a cabin floor, a plurality of holding devices positionable on the top side, each being selectively engageable with at least one first raster opening or at least one second raster opening for arresting the holding device and configured for holding an object on the seat rail, and a plurality of marking devices couplable with the seat rail, and configured for optically or mechanically indicating approaching of a first position on the seat rail corresponding to the first raster opening of a respective holding device and of a second position of the same holding device corresponding to the second raster opening, in relation to another object arrested on the seat rail, to prevent an arresting of the holding device on the seat rail on other positions.

A vehicle cabin seat arrangement includes a seat rail having a first and a second side faces; a group of passenger seats held on the seat rail by holding devices resting on a top side of the seat rail; pluralities of first and second holding blocks arranged on the first and second side faces, respectively; and a plurality of stop blocks arranged on a bottom side of a holding device To every passenger seat two first or second holding blocks are assigned, between which a holding device coupled with the passenger seat is displaceable. The respective holding device, includes one of the stop blocks arranged on the bottom side of the holding device such that the stop block is bringable into contact with the two assigned holding blocks on moving the holding device on the seat rail. Passenger seats are alternatingly assigned with first and second holding blocks.

A seat system for a cabin of a transportation system includes a first seat unit, a second seat unit, and a rail system attachable to a floor of the cabin, having two rails that run parallel to each other, for receiving the seat units on selective positions. A line-up of a plurality of first seat units and at least one second seat unit on the rail system constitutes a seat arrangement. The first seat unit includes a seat frame having a seat cushion and a back cushion. The second seat unit includes a seat frame having a foldable seat cushion and a back cushion. The second seat frame includes two forward seat legs supported on two auxiliary rail segments that are arranged between the rails in a region. The forward seat legs are guidable underneath the seat cushion of a first seat unit arranged in front of it.
