A seat air-conditioning device includes a seat pad, a back lid and a blower. The back lid covers an opening side of a ventilation groove of the seat pad. The blower generates an airflow in a ventilation passage which is defined by the ventilation groove and the back lid. The back lid has a communication port that is formed at an opposing region of the back lid, which is opposed to the blower. The communication port is configured to conduct the airflow generated by the blower. The seat pad has a plurality of support portions that contact the back lid and are formed at an overlapping region of the seat pad which overlaps with the opposing region in a thickness direction of the seat pad. The support portions are circumferentially arranged one after another around the communication port.

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 ventilated seating assembly comprises a first rigid component, a foam layer, and a second rigid component. The first rigid component comprises formed cloth and has a bonding surface, a ventilation surface opposite the bonding surface, and a 3-dimensional profile. The foam layer has an A-surface and a B-surface opposite the A-surface with the first rigid component bonded to the B-surface of the foam layer such that a portion of the B-surface includes the 3-dimensional profile. The second rigid component comprises a polymeric material affixed to a portion of the ventilation surface of the first rigid component. The first and second rigid components define a cavity including a plurality of air passageways defined by the 3-dimensional profile of the first rigid component.

A headrest ventilation assembly is configured to secure to a headrest of a seat assembly, and includes an air conduit including one or more air inlets and one or more air outlets, and an air filter disposed within the air conduit between the one or more air inlets and the one or more air outlets. The air filter is configured to remove contaminants from the air that is drawn into the air conduit before being delivered out of the one or more air outlets. The assembly can also include a fan disposed on or within the air conduit. The fan is configured to draw the air into the one or more air inlets and provide airflow to deliver the air out of the one or more air outlets. The assembly can also include one or more ultraviolet (UV) light emitters disposed on or within the air conduit. The UV light emitter(s) are configured to emit UV light into the air to sanitize the air before the air is delivered out of the one or more air outlets.

A seat assembly for a vehicle having a longitudinal axis has a seat pan, a cover support adjacent to the seat pan and a seat cover comprising an upper surface and a first longitudinally extending side surface and a second longitudinally extending side surface. A heating and cooling module is disposed at least partially within the cover support. An air inlet is in communication with the heating and cooling module. The air inlet communicates air from a port in the seat cover to the heating and cooling module. An ambient condition sensor generates an ambient condition signal. A user interface generates a user setting corresponding to a comfort condition. A controller is coupled to the ambient condition sensor and the heating and cooling module. The controller controls the heating and cooling module in response to the user setting and the ambient condition signal.

A method for controlling the air-conditioning function of a transportation vehicle seat wherein a value of an air-conditioning parameter is set by an operating element which is moved from a null position in two opposite directions. The air-conditioning parameter controls the distribution of an air-conditioning function in different regions along a first direction indicated by the geometry of the transportation vehicle seat. The separate regions include at least one first and second region. A uniform distribution of the air-conditioning function is produced in the regions in the null position of the operating element. When the operating element is moved in one direction of the two opposite directions, the value of the air-conditioning parameter for at least one of the first and second regions remains constant and is changed for at least the other of the first and second regions. Also disclosed is a device for carrying out the method.

The present teachings relate to an air conditioner device with at least one ventilation device, which has at least one fluid transport device and at least two fluid exchange devices, wherein the fluid transport device has at least two attachment openings, of which one is a fluid inlet and one additional a fluid outlet. Provision is made that in at least one operational state at least a first fluid exchange device is attached to a fluid inlet of a fluid transporting device and a second fluid exchange device is attached to a fluid outlet of a fluid transporting device.

The invention relates to a fan unit, having an air guide tube and a fan grate, wherein an air channel is formed by the air guide tube and the fan grate is arranged over a first end opening of the air guide tube in order to protect a fan wheel that can be arranged within the air guide tube. In order to improve such a fan unit in such a way that vibrations can be reduced in a simple and effective manner, at least three damping elements are arranged between the air guide tube and the fan grate in order to reduce vibrations.

A seat and cooling system for the seat include a porous seat surface, an air spacer disposed on a side of the seat surface that defines an air channel, a substantially air impermeable barrier having an opening therein in communication with the air channel and a blower configured to draw air through the seat surface and from the air channel. Air drawn from around an occupant on the seat surface draws moisture from the occupant, causing moisture to evaporate, to provide a cooling sensation

A vehicle seat air-conditioning device includes: a blower that is included in a seat; at least one of an inlet duct or an outlet duct, the inlet duct being a duct through which air is led to be drawn in from a surface of the seat by the blower, and the outlet duct being a duct through which the air led by the blower is discharged from a surface of the seat; and a controller that is electrically connected to the blower. The blower includes a current detection circuit that detects a current consumption of the blower. The controller determines whether an occupant is sitting on the seat, based on the current consumption detected by the current detection circuit.
