Methods and systems are provided for a transportation vehicle. One method includes enabling by a processor, a night mode for a seat device of an in-flight entertainment system (IFE) on an aircraft based on a night mode trigger; displaying by the processor, during the night mode, a wake-up user interface on the seat device for a passenger, when a seat device monitor backlight has turned on after the backlight was turned off, or a seat device backlight timer has triggered, where a brightness of the wake-up user interface is lower than a brightness of a default user interface of the seat device; and enabling by the processor a first set of functions of the seat device accessible from the wake-up user interface, the first set of functions being less than a second set of functions accessible from the default user-interface.

The invention relates to a sound-equipped headrest comprising at least one woofer associated with an open rear part, comprising a rear grid and/or open cell or semi-open cell foam with a density of between 8 and 60 kg/m.sup.3, so that said at least one woofer is two-directional; and at least one mid-range/tweeter, associated with a closed rear part comprising a solid wall and/or a closed cell foam so that at least one mid-range/tweeter is mono-directional.

An aircraft seat assembly for supporting a seat occupant, and a method for fabricating an aircraft seat assembly for supporting a seat occupant are provided. In one non-limiting example, the aircraft seat assembly includes a seat cushion supported by the seat structure. A vibration producing apparatus configured to produce vibrations conducive for inducing drowsiness. The vibration producing apparatus is disposed adjacent to or within the seat structure for transferring the vibrations to the seat occupant.

A method and apparatus include attaching a lighted cup holder to a seating arrangement. The lighted cup holder includes a cup holder body and a light-producing light source, with the cup holder body being attached to the seating arrangement and having a cup receptacle therein, the light-producing source being disposed within the cup receptacle for illuminating the receptacle. A light-sensitive element operatively connected to the light source selectively controls production of light by the light source in such a manner that illumination of the cup holder is provided only under conditions where visibility is reduced to the point that it becomes difficult to locate the cup holder. The light-sensitive element is mounted on a master lighted cup holder and controls illumination of the master lighted cup holder and one or more slave lighted cup holders operatively connected to the master lighted cup holder.

The technology described in this document can be embodied in a vehicle seat that includes a seat headrest portion for supporting the head of an occupant, and a seat backrest portion for supporting the back of the occupant in a seated position. The backrest portion includes an enclosure for receiving at least a portion of an acoustic transducer. The vehicle seat also includes an acoustic channel having a first end that is configured to be fitted around a driver of the acoustic transducer in an acoustically sealed configuration, and a second end. The second end is opposite the first end and disposed at a location closer to the seat headrest portion than the seat backrest portion. The acoustic channel is configured to radiate acoustic energy from the acoustic transducer through the second end.

A loudspeaker system for integration with a seat includes a first support arm and a second support arm. The first support arm extends from a first side of the support housing and supports a first loudspeaker driver assembly, and the second support arm extends from a second side of the support housing and supports a second loudspeaker driver assembly. The first loudspeaker driver assembly includes a central housing with a first array of drivers, and the second loudspeaker driver assembly includes a central housing with a second array of drivers. A retraction control mechanism moves the first support arm and the second support arm between the stowed orientation and the deployed orientation.
