To ensure that passengers sleep in a good quality, comfortable and healthy sleep during their bus, airplane and train journeys and to prevent the eclipses occurring in the neck after the journey, a passenger seat sleeping pillow has an angled working principle in accordance with head and neck anatomy. The passenger seat with angle mechanism that can be produced in the system is related to the sleeping pillow and angle mechanism provides two types of assembly (FIG. 1) or (FIG. 2), optionally manual or motorized (FIG. 19), thanks to the variable apparatus enabling the assembly of the passenger seat during or after manufacturing.

A vehicle-based mobile content delivery system comprises a projector configured to receive and project visual content, a projection surface for receiving and displaying the projected visual content, and a projector mounting system for securely mounting the projector and integrating the projector into a vehicle. The projector mounting system comprises a headrest projector mount compatible with an original headrest of the vehicle for enclosing and supporting the projector, a headrest coupling mechanism for coupling the projector to the headrest projector mount for support, and mounting channels that accommodate a range of headrest mounting rails of vehicles for connecting the projector mounting system to the vehicle.

A vehicle seat with a speaker-equipped headrest is provided, which is of a relatively simple structure to enable the speaker-equipped headrest to be easily mounted to/dismounted from a seat body after vehicle installation, and also provide increased versatility for installation in vehicles of various vehicle size classes. The vehicle seat with the speaker-equipped headrest includes: a male coupler that is connected to a speaker harness and fitted to a distal end of a headrest stay; and a female coupler that is connected to a main harness on a seat body side, and fitted to a headrest guide bracket supporting a headrest guide. Insertion of the headrest stay into the headrest guide allows the speaker-equipped headrest to be mounted to the seat body, and allows the male coupler and the female coupler to be fitted together to provide a connection between the speaker harness and the main harness.

There is provided a seat partition capable of reducing deterioration of comfort with respect to rear seats. One aspect of the present disclosure is a seat partition that includes a plate-shaped panel configured to be mounted to a seat having a headrest. The panel includes: a main portion configured to cover at least a part of the headrest from a rear thereof; a side portion configured to cover at least a part of the headrest from a side thereof; a curved portion coupling the main portion and the side portion; and at least one ridge portion extending from the main portion through the curved portion to the side portion and projecting outward of the panel.

A headrest for a vehicle with improved collision performance includes: a headrest stay provided integrally with a seat back and exposed at an upper end of the seat back; a blower connected to the headrest stay; and a rotation direction change member installed between the headrest stay and the blower, connecting the headrest stay and the blower, and configured to allow a rotation direction of the headrest stay and a rotation direction of the blower to be opposite to each other in an event of a rear collision.

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.

A device for ventilating the occupant of a vehicle seat, comprising an air inlet receiving air from a ventilation member, and comprising a first duct integrated at least in part into the backrest of the seat, a second duct integrated into a headrest mounted on the seat and supplying at least one air outlet integrated into the headrest and expelling air coming from the ventilation member, the second duct and first duct being connected by a leak tight sliding connection.

A speaker apparatus includes a pair of left and right speaker blocks that respectively have acoustic output sections and that are arranged inside a backrest. The pair of speaker blocks are arranged horizontally side by side relative to a headrest located on a front surface side of the backrest, and at least part of the headrest is located within a range of a nominal directivity angle of acoustics output from the acoustic output sections. This ensures that, of the acoustics output from the acoustic output section of the speaker block on the left side, at least some acoustics that head for the right ear are blocked by the headrest and that, of the acoustics output from the acoustic output section of the speaker block on the right side, at least some acoustics that head for the left ear are blocked by the headrest.
