A fastening device for releasable connection to a perforated rail of an aircraft and a method of assembly for such a fastening device. The fastening device comprises a housing having at least one locking head portion fixedly connected to the housing, at least one shear pin and an actuating pin. The locking head portion is insertable into a rail hole of the perforated rail and slidable along the longitudinal direction of the perforated rail to a locking position in which the locking head portion engages a slot portion of the perforated rail. The shear pin can be engaged with a rail hole of the perforated rail by axial displacement. The actuating pin is rotatably arranged relative to the housing and connected to the shear pin in such a way that a rotation of the actuating pin causes an axial displacement of the shear pin relative to the housing.

A vertical adjustment system for an aircraft seat is disclosed. The vertical adjustment system may include an actuation assembly. The actuation assembly may include an actuator configured to provide a vertical height adjustment for the aircraft seat. The actuation assembly may include a release mechanism configured to couple to a rotatory portion of the swivel plate. The actuation assembly may include a plurality of vertical stabilizer rods coupled to a portion of the tracking plate. The actuation assembly may include a pillow block assembly. The pillow block assembly may include a plurality of pillow blocks coupled to a portion of the swivel plate. The pillow block assembly may include a plurality of rollers coupled to a portion of the plurality of pillow blocks. The plurality of rollers may be configured to provide stability along the vertical stabilizer rods when the actuator provides the vertical height adjustment.

A floor panel connection system for attaching a floor panel to an airframe is disclosed. The connection system includes an offset flange insert comprising a base portion, a flange portion, and an interconnect portion. The base portion of the insert is configured to be received in a hole in an edge region of the floor panel and includes an opening that is sized to receive a fastener. The interconnect portion extends laterally from the base portion such that when the edge portion of the floor panel is overlapping a lateral edge portion of the airframe, the flange portion of the insert is beyond the lateral edge portion. The flange portion is also configured to be bonded to a bottom surface of the floor panel beyond the lateral edge portion of the airframe.

Described are modular leg assemblies for passenger seats. The modular leg assemblies can include a universal first leg member, a universal second leg member, a size specific member, and a universal seat frame tube receptor. The universal first leg member may be coupled to a first seat track fitting. The universal second leg member may be coupled to a second seat track fitting. The size specific member may be coupled to the universal first leg member and to the universal second leg member. At least one of the universal second leg member or the universal seat frame tube receptor can include a set of attachment points for coupling the universal seat frame tube receptor to the universal second leg member.

A component positioning system and method are configured to facilitate positioning of a component (such as a seat assembly) on a seat track within an internal cabin of a vehicle. The component positioning system and method include a component, and a position indicator coupled to a portion of the component. The position indicator emits a proper position indication when the component is in a proper position in relation to the seat track. The position indicator emits a remedial position indication when the component is not in the proper position with respect to the seat track.

A passenger seat or group of seats includes a tray table set into the armrest on either side of the associated seat, the tray table capable of translating lengthwise along the armrest and pivoting between a stowed configuration and a deployed configuration. In the stowed configuration, the tray table extends vertically above the armrest and may be stowed between (and partially behind) the associated seat and an adjacent seat, serving as a partial barrier between the two seats. In the deployed configuration, the tray table extends horizontally across the associated seat for use by the occupying passenger. The tray table is padded on its underside to provide the passenger with head and shoulder support when in the stowed configuration.

A bump strip includes first and second end caps and an intermediate part that, together, define a length of the bump strip. The end caps having an end part and a connecting part, and whereby one or more fastening holes is provided through the end cap connecting parts and the intermediate part such that a single fastener passing through the fastening hole of an end cap and the intermediate part secures the bump strip to a surface to be protected.

A passenger seat arrangement for a vehicle including first and second partition walls positioned in spaced apart relation forming an area therebetween, each of the walls including at least a portion angled relative to an aisle and each of the walls having an end position proximate the aisle such that the area formed between the walls is directly accessible from the aisle. A passenger seat positioned in the area is coupled to a guide mechanism such that the passenger seat is configured to travel within the area between a first position distal from the aisle and a second position proximate the aisle for facilitating transfer of a person of reduced mobility (PRM), and in some implementations through an intermediate position for enhancing socialization between the passenger seat and an adjacent passenger seat.

A floor structure for an aircraft includes a rail that defines a recess having an opening and a bottom and designed to receive one or more attachment elements, a covering element arranged above a segment of the recess so as to provide a complementary bearing surface above the opening, and a cellular supporting structure having a first end that rests on the bottom of the recess, and a second end supporting the covering element. Thus, the covering element can be sufficiently thin to avoid or limit the formation of steps at the surface of the floor structure.
