Provide are a device for adjusting softness of a vehicle seat, a device for adjusting comfort of a seat, and a vehicle seat. The device for adjusting softness of a vehicle seat has at least one soft inflatable bag that can be integrated in the seat. The soft inflatable bag is connected with at least one air path. The soft inflatable bag is filled with a flexible filler. Gas is charged into or discharged from the soft inflatable bag through the air path to adjust the softness of the surface of the seat. The soft inflatable bag is provided therein with a height limiting structure configured to limit the partial expansion height of the soft inflatable bag when inflated.

A vehicle seat is provided with a temperature-control system which is connectable or connected to a temperature-control circuit that conveys a temperature-control medium. Thermal energy from the temperature-control medium conveyed in or to at least one temperature-control heat exchanger of the temperature-control system is deliverable to and/or absorbable from the surroundings. The vehicle seat has at least one flow generation system, in particular a fan system, which generates a gas flow. The at least one flow generation system is controllable by a controller, with the temperature of the gas flow being controllable via at least one temperature-control heat exchanger and/or via an electrically operated temperature-control element.

A seat cushion S1 of a vehicle seat S includes: a pad member 10 including a base pad 11 and an intermediate pad 12 overlapped on the base pad 11; a fan 31 provided so that air passes through the pad member 10; air passage holes 11h and 12h respectively formed in the base pad 11 and the intermediate pad 12; and a pull-in hole provided at a position different from the air passage hole 12h in the intermediate pad 12 and a position of the intermediate pad 12 with respect to the base pad 11 is held in such a manner that a skin pull-in trim cord enters the pull-in hole while the intermediate pad 12 is overlapped on the base pad 11 so that the air passage holes 11h and 12h communicate with each other.

A ventilated molded seat trim cover for a vehicle seat and a ventilated vehicle seat having a ventilated molded seat trim cover, comprising a stacked assembly of an upper textile layer, a first adhesive layer, an air permeable polyurethane cellular foam interlayer thermo-moldable at temperatures between about 104° C. and about 127° C., a second adhesive layer, a thermoplastic polyurethane (TPU) film, a third adhesive layer, and a scrim backing layer. The stacked assembly is compression molded in a 3-dimensional mold while at least a portion of the foam interlayer is heated to a temperature between about 104° C. and about 127° C. to form the ventilated molded seat trim cover. The TPU film prevents airflow passing through a bottom surface of the seat trim cover. Airflow in the foam interlayer can pass through the upper textile layer.

Disclosed are a system and method for controlling an air ventilation volume of a vehicle seat in which sweat generation rates, relative humidities, etc. of respective body parts of a passenger sitting on the vehicle seat are predicted in advance and an air ventilation volume is concentratedly distributed to a passenger's body part predicted to have a high sweat generation rate and a high relative humidity among the passenger's body parts in advance so that ventilation of the seat is carried out before the passenger feels inconvenience due to the locally over-wet state of the passenger's body, thereby allowing the passenger to feel comfort in a sense of sitting on the vehicle seat all the time.

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.

Provided is vehicle seat with a seat cushion and a seat back, the vehicle seat comprising: a duct disposed astride the seat cushion and the seat back, and configured to connect an air passage and a blower, the air passage being formed in the seat cushion and the seat back; and a side frame cover configured to cover part of the duct. The duct includes a first duct member and a second duct member connected to the first duct member. The side frame cover is configured to cover at least part of a first connected section that is a section at which the first duct member and the second duct member are connected.

An insert comprising: (a) a cover layer; (b) a spacer layer located below the cover layer; (c) a connection material that is adapted to extend between and connect the cover layer to a trim layer so that the insert is fixed to the trim layer.
