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.

A vehicle seat includes right and left side frames 10, and an elastic member (cushion spring 20) run between the right and left side frames 10. The right and left side frames 10 include side walls 11 disposed opposite to each other in a lateral direction, and flange portions (upper flange portions 12) respectively extending laterally inward from the side walls 11, and the elastic member is attached to the flange portions.

Seat assemblies (200) including structural components (212, 222, 232) made of foam are described. A seat sub-assembly (210, 220, 230) can include a frame (214, 224, 234) and a foam support (212, 222, 232). The foam support (212, 222, 232) can be coupled to the frame (214, 224, 234) for receiving a load on the seat sub-assembly (210, 220, 230), dissipating at least half of the load, and dispersing the load through the frame (214, 224, 234).

A cushioning element for use in a vehicle, for example in an aircraft, includes at least one tuned absorber embedded within the cushioning element. The tuned absorber is tuned to absorb noise at a predetermined frequency of at least 20 Hz. A method of providing noise absorption within a cabin of a vehicle includes determining a predetermined frequency of at least 20 Hz of an undesirable noise within the cabin, and configuring an internal structure of a cushioning element to define a tuned absorber tuned to absorb noise at the predetermined frequency, the cushioning element in use being located in the cabin.

The invention relates to a seat for a vehicle, preferably for a land craft, a watercraft, and/or an aircraft, comprising at least one multilayer structural component (1) with at least one first (6) and at least one second ply (5) of a composite material, in each case containing fibers which are integrated into a thermoplastic, and with a layer (7) which is arranged between said plies and is made of at least one foamed thermoplastic; to a method for producing same, said method having at least the following steps (A): providing at least one first and at least one second ply of a composite material, in each case containing fibers which are integrated into a thermoplastic, (B) thermoforming the first ply of composite material into a lower seat shell, (C) thermoforming the second ply of composite material into an upper seat shell, (D) arranging the lower seat shell and the upper seat shell in a tool, such that a gap is formed between the two seat shells, (E) introducing foamed particles made of a thermoplastic into the gap, and (F) pressing the two seats shells and the foamed particles in order to obtain the seat; and to the use of the seat in a vehicle, preferably in a land craft, a watercraft, and/or an aircraft.

A seat pan for a vehicle seat. The seat pan includes a rear portion and a front portion. The seat pan includes a flexible area arranged between the rear portion and the front portion, said flexible area enabling the front portion to be arranged in a tilted state relative to the rear portion and wherein the seat pan is formed in a single piece.

An assembly for a vehicle seat that includes: a support element defining a through opening, a padding element attached at least in part to the support element, and a ventilation system assembled to the support element in fluidic communication with the through opening. An inner surface of the support element and/or an inner surface of the padding element define at least one groove. An inner surface of the groove, the inner surface of the support element, and an inner surface of the padding element define an internal volume there between in fluidic communication with the through opening.

A seat includes a seating portion, a backrest, two pairs of vibrators and a vibration absorbing member, and constitutes a driver's seat of a vehicle. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the seating portion, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the backrest, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region.

An arrangement structure for a biological sensor includes a biological sensor of a non-contact type provided in a seat on which a human is seated. The biological sensor detecting biological information of the human with electromagnetic waves. The biological sensor is arranged at a position in the seat avoiding a member that constitutes the seat and interferes with passage of the electromagnetic waves.
