The present invention relates to an aircraft seat comprising: a guide rail (26); a rack (34); an actuator (30) provided with a gear (31); at least one connection portion (35) providing a mechanical connection between the guide rail (26) and the rack (34),
characterized in that the connection portion (35) included a zone (36) of mechanical weakness and in that a first bearing element (37) and a second bearing element (38) are disposed on either side of the rack (34), such that, if the deformation of the seat generates a movement of the gear (31), said gear (31) or the corresponding shaft (32) comes into abutment against one of the bearing elements (37, 38) and in this way deforms the connection portion (35) along the zone (36) of mechanical weakness.

A system for restraining a cargo container in a cabin of an aircraft is disclosed. The system may include a guide rail, a rail and a plurality of rollers. The guide rail spans a length of a seat track and is releasably coupled to the seat track at one or more locations on a bottom surface of the guide rail. The rail is attached to a surface of the cargo container. The rail engages with the guide rail. The plurality of roller are coupled to the guide rail. The rollers engage a surface of the rail. The rail has two side surfaces that partially enclose two side surfaces of the rollers. When the cargo container deviates from a path defined by the guide rail, one of the side surfaces of the rollers abuts one of the side surfaces of the rail.

A seat unit for an aircraft that can be directly fixed at three points to a seat track provided on the floor of the aircraft. One representative seat unit and attachment method thereof relates to a seat unit comprising a lower structure of the seat unit and three fixtures configured to attach the lower structure directly to a pair of seat tracks of a mobile body, wherein the three fixtures include a lateral position adjustment member configured to laterally adjust a fitting position with the pair of seat tracks, a first fixture is fixed to one of the pair of seat tracks, a second fixture is fixed to one of the pair of seat tracks at a point separated from the first fixture, and a third fixture is fixed to another one of the pair of seat tracks at a corresponding portion between the first fixture and the second fixture.

A swinging seatpan assembly for a passenger seat includes a fixed seatpan frame attached to the seat structure and a mobile seatpan frame pivotably attached to the fixed seatpan frame by rollers configured for translation through slots in the fixed seatpan frame. Passengers occupying middle and aisle seats of a multiple-seat block or assembly may engage their respective swinging seatpan assemblies to allow an occupant of a window seat to enter/egress their seat without the middle-seat and aisle-seat passengers leaving their seats for the aisle. For example, the passenger may engage a release to unlock and push the mobile seatpan frame so that the mobile seatpan frame pivots rearward/downward, temporarily increasing the seat pitch distance and allowing the window-seat passenger increased egress space.

A passenger seat having a frame is proposed, wherein the frame is intended for securing to a floor of a passenger cabin, wherein the frame comprises a seat divider and beams that run transverse to the seat direction, wherein the seat divider is held by the beams, wherein a housing is disposed on the seat divider, wherein the housing at least partly surrounds a backrest. According to the invention, a structure component is disposed on the seat divider, with an attachment unit for a safety belt for a passenger disposed on the structure component.

A rail for the fastening of equipment elements, such as, in particular, seats, in aircraft, includes a holding region for connection to an equipment element of an aircraft, and a support region to fasten the rail to a carrier element of the aircraft. The rail has a metallic shell which is, for example, made of titanium and which is filled with a fiber-reinforced thermoplastic filler material which is reinforced by short fibers. To produce the rail, a metallic molded part is used as a casting mold and is filled, for example by injection, with the filler material and, after the rail has been produced, forms the metallic shell for the filler material.

A holding system for a wheelchair in an aircraft is proposed, including a plate-shaped base unit having first fastening elements at an underside configured to be connected to complementarily shaped second fastening elements in the form of seat rails on a floor or surrounding structure in the aircraft for fastening the base unit, a front holding unit and a rear holding unit arranged on an upper side of the base unit at a distance from each other and defining therebetween a placement area for a wheelchair. The front holding unit and the rear holding unit are configured to form a releasable form-fit connection with the wheelchair disposed on the placement area so that the wheelchair is braced between the front holding unit and the rear holding unit. The holding system is configured to fix the wheelchair stationarily to the floor during operation of the aircraft.

A passenger seat assembly includes a riser attached to an upper surface of a floor of the vehicle, a seat attached to an upper surface of the riser, and at least one shell portion attached to the upper surface of the riser. The riser includes at least one door for accessing an interior volume of the riser. At least a portion of the interior volume of the riser is a luggage storage volume.

A seat system for a passenger aircraft. The seat system includes a passenger seat frame (i) a plurality of spreader bars and (ii) a plurality of laterally extending spar tubes connecting the plurality of spreader bars to one another and at least one canted leg assembly connected to the seat frame for attachment to fixed, spaced apart attachment points on a supporting surface of the passenger aircraft. The canted leg assembly includes: (i) a front leg portion including a front joint clamp for receiving one of the plurality of laterally extending spar tubes in a non-perpendicular attachment point; and (ii) an aft leg portion including an aft joint clamp for receiving another one of the plurality of laterally extending spar tubes in a non-perpendicular attachment point, whereby the seat system is adapted to be laterally positioned and attached to provide different spaced apart passenger seating configurations. A seat back tray table may be attached to the back of the passenger seat frame.

A rack is made from a plurality of laminated layers. Each layer defines an alignment feature that allows all of the layers to be affixed to a base plate of an aircraft seat assembly and align the teeth of the rack to within five ten-thousandths of an inch. The rack includes a straight portion and a curved portion such that a pinion gear on the aircraft seat assembly can move the aircraft seat assembly along tracks with straight and curved portions.
