A seat assembly (100) configured to be employed in vehicle seats such as aircraft passenger seats. The seat assembly includes a seat frame (102) having first and second spaced frame members (108a, 108b) and first and second spaced transverse beams. A plurality of springs (112) positioned proximate an aft end of the seat frame generally above the second transverse beam span between the first and second frame members. A support member (116a, 116b) is attached to the plurality of springs and to a seat back (106) attachable to the seat frame. A cushion assembly (104) mounts on the seat frame such that the aft end rests on the plurality of springs while the forward end rests on the front transverse beam. In use, as the aft end of the cushion assembly deflects downward toward the second transverse beam the forward end simultaneously rotates around the first transverse beam.

A drain valve assembly comprising: a valve housing having an upper section (420) and a lower section (410), the lower section (410) comprising an inlet port (500) and an outlet port (600) and a water collection chamber between the inlet port (500) and the outlet port (600), the upper section (420) including a pressure diaphragm (160) across the upper section (600), the drain valve assembly further including a poppet valve (800) positioned in the housing and extending between the lower section (410) and the upper section (420), the poppet valve (800) arranged to fluidly seal the lower section from the upper section (410), the poppet valve in the water collection chamber being arranged to be normally sealingly positioned across the outlet port (600) to prevent water exiting the water collection chamber to the outlet port (600), the poppet valve (800) attached to the pressure diaphragm (160) in the upper section (420), the drain valve assembly further comprising a pressure line for providing a pressure signal to the upper section (420) such that when the pressure from the pressure line in the upper section (420) exceeds a predetermined opening pressure it causes the pressure diaphragm (160) to lift and to thus lift the poppet out of sealing engagement across the outlet port (600) such that water can drain to the outlet port from the water collection chamber; wherein the poppet valve (800) has a hollow body defining a channel (850) from a first end of the poppet valve (800), adjacent the outlet (600), and a second end of the poppet valve (800) adjacent the pressure diaphragm (160), and wherein the housing defines a vacuum cavity (810) across the second end of the channel, such that a negative pressure acting on one end of the poppet valve is balanced by a negative pressure acting in the opposite direction at the other end.

There is provided herein a door for an aircraft galley oven including: a frame; an external panel fixed to the frame; an internal panel selectively moveable proximally and distally with respect to the frame between a retracted position and an extended position; and a reversibly compressible insulation layer between the external panel and the internal panel and fixed to the external panel and the internal panel, wherein the compressible insulation layer is compressed when the internal panel is in the retracted position and expanded when the internal panel is in the extended position. There is also provided an aircraft galley oven including such a door.

An aircraft insert can include a body (101) and a wireless network module (103) configured to create an insert host network for one or more devices to connect to the wireless network module in a host mode, and to connect to an aircraft network in a client mode. The insert can include a LED mounted on or within the body, the LED readable by a Personal Electronic Device (PED) (107) and having insert host network information to allow the PED to connect to the insert wireless network when the wireless network module is in the host mode. The wireless network module can be configured to receive aircraft network information from the PED in the host mode to connect to the aircraft network when in the client mode.
