Various implementations include seats and related loudspeaker assemblies. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly associated with the backrest portion. The loudspeaker assembly can have an acoustic directivity angled upward above a nominal ear position of an occupant.

Described is an adjustable friction slider assembly having a rail member and a carriage assembly moveably coupled to the rail member, the carriage assembly having a bracket member and a plurality of roller elements moveably coupled to the rail member and coupled to the bracket member using a plurality of attachment members, the plurality of roller elements comprising at least one adjustable roller element coupled to the bracket member using a moveable attachment member, wherein moving the moveable attachment member adjusts a friction between the plurality of roller elements and the rail member.

A device for automatically adjusting an angle of a monitor on a vehicle seat back includes: a fixation bracket on a front seat back upper-frame; a first rotation bracket on an upper portion of the fixation bracket; a second rotation bracket on a lower portion of the fixation bracket; a monitor on a front surface of the first rotation bracket; a motor on a bottom surface of the second rotation bracket; an angle adjustment bar integrally combined with a rear surface of the first rotation bracket; a lead screw, whose lower portion is connected to an output shaft of the motor, and whose upper portion passes through the second rotation bracket; and an ascending and descending member having a threaded hole such that the ascending and descending member fastened to the lead screw while being fastened to an end portion of the angle adjustment bar.

Various implementations include seats and related loudspeakers. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly. The loudspeaker assembly includes at least one driver for generating an acoustic output; and an acoustic exit fixed in the seat backrest portion and angled to provide the acoustic output to a location below a nominal ear position of an occupant of the seat, wherein a firing angle of the at least one driver provides the acoustic output to achieve a consistent frequency response across a range of positions deviating from the nominal ear position.

The invention provides an electrically driven stowable and deployable table mounted on a support structure, wherein the table comprises a switch mechanism operable by a user to select between a first, automatic, operation for stowing and deployment of the table, and a second, user adjustable operation for user adjustment of the deployed position of the table.

Described are tray table assemblies for a passenger seat, such as an aircraft passenger seat. The tray table assembly includes a tray table with a top surface and a holder assembly. The holder assembly includes a first holder pivotably attached to the tray table and a second holder pivotably attached to the first holder.

An entertainment system including a removable seat-back display unit and a docking station. The seat-back display unit can include a rotating latch butterfly release mechanism that prevents unauthorized release of the display unit from the docking station. The system can include a three-point attachment system that provides additional protection against accidental detachment of the display unit, and provide safety in the event of partial dislodging. The system can include a current control pin system that ensures that current is not provided from the docking station to the display unit until the respective connectors have been properly engaged. The system can further include a floating pin connector dock that can allow for installation of the display unit even when the connectors of the display unit and docking station become misaligned. The system can also include a heat dissipation system that employs the docking station to share the heat dissipation load with the display unit.

A display screen mount mounts a display screen (6) to the rear of a seat (1). The mount includes a guide which defines a guide path to guide the display screen support (7) from a stowed position to a deployed position. The guide path also allows for adjustment of the viewing angle in the deployed position. The guide path has a linear portion (105) along which the display screen support (7) is guided into a deployed position in which the screen is visible to the user and a non-linear portion (106) which allows different viewing angles of the display screen (6) to be adopted in the deployed position.

The present invention provides an object holding device used in a vehicle seat. The object holding device comprises an object holder coupled to an extendable device via a deployment rod and is extended and retracted in and out a map pocket of the vehicle seat. An extendable rod of the extendable device is pivotably connected with the deployment rod and lockable with the deployment rod. At a first position where the deployment rod forms a first angle with the extendable rod, the object holder is changeable at a slanted position and a leveled position to hold an object.

A video display system for a passenger seat of a vehicle. The video display system is configured to be mounted to a seatback of each passenger seat or to other structure such that the system may be utilized by the passenger. The display system includes a video display assembly having a display housing configured to be mounted to structure in the vehicle. A video monitor is housed within the display housing. The video display assembly includes a depending tab portion disposed below the area of the video monitor. The depending tab portion includes a tab display capable of displaying a computer generated graphic and/or information. The display system may also have one or more indicator lights provided adjacent the external edge of the display housing.
