A seat, in particular an aircraft seat, having a seat support structure having at least one seat surface with a seat surface frame and a backrest with a backrest frame being pivotable relative to the seat surface, a base support element supporting the seat support structure, and a seat adjustment arrangement, which includes at least one coupling unit movable relative to the base support element, the coupling unit is configured to connect the seat surface frame and the backrest frame to one another and which is provided with at least one bearing element, and which includes at least one guide element in which the bearing element is movably guided. The seat adjustment arrangement being adapted to transfer the seat support structure into a sitting position, a comfort position or lying position by displacing the bearing element along the guide element.

The present invention essentially relates to a method for assembling a beam and a structural element of an aircraft seat, characterised in that it comprises: a step of producing at least one recess in an inner face of a beam passage area of the structural element, a step of inserting the beam into the beam passage area, and a step of deforming the beam such that a deformed portion of the beam penetrates into the recess of the beam passage area.

An aircraft seat includes infinitely adjustable, lateral tilt control within a specified range. The aircraft seat includes a stationary support, a tilting frame rotatably or translatably attached to the stationary base, and a tilt control mechanism to adjust the tilt within the defined range and positively lock the frame without back-driving. The tilt control mechanism may include a plurality of linkages connected to the stationary support and the tilting frame, and to each other via a threaded block; a threaded shaft adjusts the linkages and thereby adjust the tilt. Alternatively, the tilt control mechanism comprises a curved rack and a pinion. The threaded block and threaded shaft, or the rack and pinion define ACME threads to prevent back-driving.

The present disclosure provides a swivel stop comprising a rotating member, a first boss coupled to the rotating member and a second boss coupled to the rotating member, and a second plate having a first interference surface and a second interference surface. An interference between the first boss and the first interference surface and the second boss and the second interference surface tends to limit the rotation of the rotating member with respect to the second plate. The swivel stop may further comprise a rail wherein the second plate is configured to translate along the rail.

An aircraft seat device has a multi-part backrest frame unit comprising at least one first side frame element, at least one second side frame element, which is arranged on a side of the backrest frame unit that is opposite from the first side frame element, and at least one transverse frame element which is realized separately from the side frame elements and connects the side frame elements, wherein the transverse frame element is realized at least substantially plate-shaped.

Described are crossbeam assemblies for installing a furnishing to a passenger compartment. The crossbeam assemblies can include a first structural member configured to span two floor-mounted channels in a passenger compartment, and at least two attachment elements that are slidingly connected with the first structural member. The attachment elements are repositionable along the first structural member to mate with the floor-mounted channels, and lockable to retain the first structural member with respect to the two floor-mounted channels when the first structural member is attached.

An adjustable swiveling passenger seat assembly is disclosed. The adjustable swiveling passenger seat assembly includes a set of base rails coupled to a floor. The adjustable swiveling passenger seat assembly further includes a plurality of pitch clevises coupled on a top surface of each of the set of base rails. The adjustable swiveling passenger seat assembly includes a swivel outer plate aligned in parallel relative to the floor. The swivel outer plate of the adjustable swiveling passenger seat assembly further includes a plurality of slots located on corners of the swivel outer plate and a plurality of spacers disposed within the plurality of slots.

A plinth attachment system for attachment to at least one track includes: a first plate having a first side configured for mounting to a longitudinally extending track, and a first mounting feature for mounting a first structure; and a second plate having a first side configured for mounting to the track, and a second mounting feature for mounting a second structure. When mounted on the track, at least one interlinking feature of the first side of the first plate and at least one interlinking feature of the first side of the second plate interlock at the track, and, the first mounting feature and second mounting feature are aligned at essentially equivalent longitudinal positions.

Described are passenger seats having a seat frame and a seat bottom slidingly and pivotally attached to the seat frame that, when the passenger seats are reclined, are configured to articulate forward from an upright configuration of the passenger seat to a second seat position corresponding to a reclined configuration of the passenger seat. The seat bottom can include an aft articulating mechanism that defines a declining first path in an aft-to-forward direction to cause the aft end of the seat bottom to drop when the seat bottom articulates forward; and a forward articulating mechanism connected with the seat bottom near a forward end of the seat bottom that defines a second path shaped to cause the forward end of the seat bottom to move upward when the seat bottom articulates forward, such that the seat bottom tilts aft in response to articulating forward when the passenger seat is reclined.

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.
