Vehicle seat assemblies including support structures having at least two supports parts coupled at an articulating joint and a pneumatic actuator system including at least one pneumatic chamber inflated and deflated to articulate the articulating joint to move one support part relative to the other or to synchronize movement of two support parts. Support structures can include a backrest coupled to a seat bottom or leg rest coupled to a seat bottom, wherein articulation of the joint causes movement of the backrest or leg rest along a non-hinged trajectory to change a sitting position of the support structure, change seat orientation, and generally improve seat comfort.

Provided is a cushion for an aircraft seat including at least one antimicrobially active pad made of at least one plastic material, the pad having at least two antimicrobially active substances contained therein. The antimicrobially active substances do not contain silver or silver ions, and at least one antimicrobially active flame retardant fabric covering side at least one pad.

In a first aspect, provided is a cushion for an aircraft seat including at least one cushion having an upper side and a lower side of at least one plastic foam; at least one sensor system, where at least one sensor system is arranged in a region of the cushion adjacent the bottom surface of the cushion; and at least one flame retardant fabric covering at least one side of the at least one cushion. In a second aspect, provided is a cushion for an aircraft seat including at least one pad made of at least one plastic; at least one stabilizing means embedded in the at least one plastic; and at least one sensor system arranged on the at least one stabilizing means.

A vehicle seat having at least one seat shell, the seat shell having a frame with two spaced-apart frame units and a shell surface arrangement extending from one of the frame units to the other frame unit. The shell surface arrangement has a net-like structure having a first fiber-reinforced plastic, and the seat shell has at least one holding element connected to a corresponding receiving element for fastening the seat shell.

A spring-based seat diaphragm may include at least one support diaphragm component. The at least one support diaphragm component may be transversely coupled to the first structural beam and the second structural beam. The spring-based seat diaphragm may include at least one spring. The at least one spring may be proximate to the at least one support diaphragm component. The at least one spring may be parallel to or positioned transverse to the at least one support diaphragm component between the first primary spreader and the second primary spreader. The at least one spring may include a plurality of bends configured to distribute user weight applied to a cushion installed on the aircraft seat over the spring-based seat diaphragm. The spring-based seat diaphragm may be configured to support an aft portion of the cushion. The first structural beam may be configured to support a forward portion of the cushion.

The present disclosure provides cover systems for covering components of a cabin interior of a vehicle, such as an automobile, a train car, a bus, a boat, or an aircraft, among others. For instance, the cover systems may cover one or more of a seat and a floor, among others, of the cabin interior. The fabric cover systems may absorb or partially absorb one or more of low-frequency sounds, such as low-frequency noise emitted by an engine, and high-frequency sounds, among others. The fabric cover systems may absorb or partially absorb odor molecules. The fabric covering systems may include multiple layers. For instance, one of the layers may include activated carbon fibers. The activated carbon fibers may absorb or partially absorb one or more of sounds, liquids, and odors, among others.

Improved seating arrangements for a vehicle cabin of a passenger transport system, in particular of an aircraft are disclosed. Examples herein provide improved seating arrangements providing a high density of seats and increased PAX numbers while ensuring privacy, comfort and a direct aisle access to each passenger. For example, the seating arrangements provided herein are applicable to narrow body aircrafts and wide body aircrafts, in particular in view of business class solutions.

Described are passenger seat assemblies that include a passenger seat frame (212), a first passenger seat element (224) connected with the passenger seat frame, and a second passenger seat element (226) configured to removably connect with the first passenger seat element. Each of the first and second passenger seat elements includes a respective conductive touch fastener (228, 232) that, together, complete a circuit when the second passenger seat element is connected with the first passenger seat element. The circuit can be used as a sensor to determine whether the first and second passenger seat elements are connected.

Described are passenger seat bottom assemblies that include a layered seat bottom assembly formed of a first face sheet, a lightweight core layer, and a second face sheet bonded together, preferably in a flat or substantially flat arrangement. The core layer can be a honeycomb structure, e.g. a metal or aluminum honeycomb, or a foam, that confers a high strength and stiffness to the seat bottom assembly with minimal forming and minimal weight.

A compressible cushion may include a base structure and a plurality of foam layers positioned on a seat pan of the aircraft seat. The plurality of foam layers may include a first foam layer stacked on the base structure, and at least a second foam layer stacked on the first foam layer. A density of the at least a second foam layer may be less than a density of the first foam layer. The first foam layer and the at least a second foam layer may be cut at a length corresponding to a length of the seat pan when in an extended position. The first foam layer and the at least a second foam layer each may include a plurality of cuts, which may be configured to compress when the seat pan actuates between the extended position and a retracted position.
