A ventilated seat system for a vehicle includes a seating assembly including a seatback operably coupled to a seat base. A blower is coupled to the seating assembly. The blower generates a sound transmission when activated. The blower includes a housing defining an inlet and an outlet. A first metamaterial silencer is coupled to an interior surface of the housing proximate to the inlet, and a second metamaterial silencer is coupled to the interior surface of the housing proximate to the outlet. Each of the first metamaterial silencer and the second metamaterial silencer reduces the sound transmission generated by the blower.

A system and method for entrainment of a user based on bio rhythm of the user. The system includes an analyzing unit and an entraining rhythm generation unit. The analyzing unit receives bio rhythm information of a user, analyzes the bio rhythm information, and sets an entraining target based on an analysis of the bio rhythm information. The entraining rhythm generation unit generates an entraining rhythm based on the entraining target for providing an entrainment experience to the user, and control one or more human sensory inputs to the user based on the entraining rhythm. The bio-rhythm information may be information related to a breathing rate, a heart rate, brain waves, circadian rhythm, body rhythm, emotion, etc. The entrainment experience may be provided either inside or outside a vehicle.

Provided are a seat temperature control system and a control method thereof comprising a sensor unit collecting integrated information including vehicle information on vehicle environment, seat information on a state of a seat, and occupant information on a state of an occupant; an air conditioning device regulating airflow volume and temperature of an indoor space or a seat of the vehicle; and a control unit having a prioritizing criterion on the priority among a plurality of pieces of integrated information, prioritizing the plurality of pieces of integrated information according to the prioritizing criterion, setting target temperature of the output from the seat or the air conditioning device according to the plurality of prioritized pieces of integrated information, and controlling the air conditioning device in order for the temperature of the output from the seat or the air conditioning device to reach the target temperature.

A duct attachment molded within a cellular foam pad is disposed between an air duct and an internal air flow channel of an automotive seat assembly for increasing the air flow between the air duct and the seat assembly. The duct attachment is insert molded within the foam pad which provides a mechanical connection and a seal between the duct attachment and the foam pad and reduces the potential for air leaks between the duct attachment and the foam pad.

The invention relates to a housing (1) for a fluid machine, in particular for a radial fan (2), comprising at least one housing part (3), wherein the housing part (3) has at least one inlet opening (7), wherein the housing part (3) can at least partially delimit a fluid chamber (8) for receiving at least one fan wheel (9), and wherein the inlet opening (7), at least in part, has a curved inlet surface (11). To produce a housing (1) for a fluid machine, in particular a housing (1) for a radial fan, preferably for use in a car seat and offering reduced noise emission together with good performance, the curved inlet surface (11) has at least in part the form of a logarithmic spiral in cross-section, and/or at least one guide element (21) extends from the inlet surface (11) towards a central axis of the inlet opening (7), and/or on the inside (17) of the housing part (3) there is provided a circumferential recess (25) which at least partially circumferentially surrounds the inlet opening (7) and/or a circumferential projection (6) which at least partially surrounds the inlet opening.

A ventilation and massage device for a seat, may include a seat foam pad including a plurality of air discharge holes formed in the seat foam; an air distribution duct mounted in a space in a rear surface of the seat foam pad and fluidically-connected to the plurality of air discharge holes, the air distribution duct being configured to distribute air to the air discharge holes; massage units mounted on a bottom surface of the air distribution duct, the massage units being configured to move forwards and backwards to open or close the air discharge holes or penetrate the air discharge holes; and a controller electrically connected to the massage units and configured to control an amount of movement of the massage units based on information related to a body pressure of an occupant accommodated in the seat and information related to a temperature and humidity at a contact portion between the occupant and the seat.

A thermal system for a vehicle seat. The thermal system includes a seat insert; a connector having a first portion at least partially located within the seat insert; and an air mover connected to the seat insert via the connector. The air mover is adapted to generate an air flow within the insert. The first portion of the connector includes one or more air directors within the insert that are configured to change a direction of the air flow within the insert.

It is an object to provide a seat of which a seating comfort can be improved. The seat includes a seat cushion pad having an air passage formed inside and an air vent formed at an upper surface thereof, and is configured to allow air in the air passage to blow out through the air vent, wherein the seat cushion pad includes a pad body and a cover member which is disposed over the pad body to form the air passage between the pad body and the cover member and in which the air vent is formed, and a front end portion of the cover member extends downward over a front end portion of the pad body.

A vehicle seat includes a pad having an air passage, a skin material, and a skin locking clip embedded in the pad and configured to tuck in a prescribed linear portion of the skin material The pad includes a main body member in which the skin locking clip is embedded, an intermediate layer member arranged on the main body member, and a surface layer member arranged on the intermediate layer member. The main body member includes a linear bulging portion extending along the linear portion and bulging so as to define a plane substantially identical to a surface of the surface layer member, and the skin material is tucked in by the skin locking clip at a portion extending further from the surface layer member than the linear bulging portion.

A method for fabricating custom seat bolsters includes receiving a first image of a user in a first pose and a second image of the user in a second pose. The method further includes generating a 3D body scan model based on at least the first image of the user and the second image of the user. The method further includes determining a design for a set of seat bolsters for the user based on the 3D body scan model. The method further includes providing the set of seat bolsters for the user based on the determined design.
