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.

An actuating pillow includes a pillow body and a plurality of artificial muscles arranged within the pillow body. Each of the artificial muscles includes a housing having an electrode region and an adjacent expandable fluid region, an electrode pair positioned in the electrode region of the housing, and a dielectric fluid housed within the housing. The plurality of artificial muscles are configured to actuate from a non-actuated state to an actuated state, actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region and increases a height of the pillow body.

A vehicle seat is provided with a seat pad formed of a foam material defining a seating surface for supporting an occupant and a rear surface opposite the seating surface. A speaker cavity for receiving a speaker assembly is formed in the pad and extends from the rear surface toward the seating surface. At least one speaker retention bracket is disposed in the speaker cavity. The retention bracket is co-molded with the pad so at least a portion of the retention bracket is encapsulated in foam material to retain the bracket in the cavity, the retention bracket having at least one retention feature extending within the cavity to cooperate with the speaker assembly and retain the speaker assembly in the pad. The speaker retention bracket is configured to mount a speaker assembly within the cavity to allow acoustic radiation to be transmitted through the foam material to a seated occupant.

A system for sterilizing an interior of a vehicle includes: a sterilizer disposed on a driver's seat of the vehicle and configured to sterilize the interior of the vehicle; a driver detection sensor configured to detect a presence of a driver inside the vehicle; a seat movement adjustment mechanism configured to move the seat; and a controller configured to, in response to receiving a non-detection signal from the driver detection sensor, send driving signals to the seat movement adjustment mechanism and then apply a sterilizer operation signal for operating the sterilizer for a certain period of time upon movement of the driver's seat.

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.

A noise-canceling headrest for a vehicle seat, comprising a central part and two side parts, at least one loudspeaker, a microphone, an audio source playback module capable of transmitting an audio signal to the loudspeaker, a noise sensor, and a signal processing circuit configured for: receiving a noise signal and determining a noise correction function, receiving an error signal from the microphone, and updating the noise correction function, generating a noise correction signal by applying the noise correction function to the noise signal, generating a control signal intended for the loudspeaker, by adding together the noise correction signal and the audio signal.

A speaker system includes a cushion body with which a person comes into contact when sitting therein, and a speaker, a front of which is covered by the cushion body. The cushion body includes: a three-dimensional mesh-like elastic part that is formed by a three-dimensionally entangled fiber and bears a load of the person; and a cover member that covers surroundings of the three-dimensional mesh-like elastic part. The cover member includes a first cover member that covers the part of the surroundings of the three-dimensional mesh-like elastic part located at the front of the speaker, and a second cover member that is a remainder of the cover member excluding the first cover member. The first cover member has a higher acoustic transmissivity than the second cover member.
