20080203781 | Air Nozzle Arranged In The Head Rest Of A Vehicle Seat - A motor vehicle seat has a headrest which is supported by a backrest. At a front side of the headrest, which faces toward the seat occupant, the air nozzle opens out of an air supply device for supplying the head, shoulder, and neck region of the seat occupant with an air flow. The air nozzle is provided with guide elements for directing the emerging airflow. Each component of the air nozzle is arranged so as to be recessed with respect to the front side of the headrest by a comfort dimension. | 08-28-2008 |
20080300749 | Air Supply Mechanism for a Vehicle Seat, and Method for the Operation Thereof - An air supply mechanism for a vehicle seat comprises a control device for driving a fan and a heating element connected downstream of the fan. When the vehicle is unlocked, a vehicle door is opened and/or a folding-top switch is actuated in order to open the folding-top, the control device causes a heating element to be preconditioned. When there is a switching-on signal for the air supply mechanism, the control device ends the preconditioning and switches on the heating element and the fan. The heating element and fan are subsequently regulated by the control device as a function of vehicle speed and external temperature. In this manner, a seat occupant does not experience an initial draft or a delayed switching-on reaction but rather experiences a pleasant warmth even immediately after the air supply mechanism is switched on. | 12-04-2008 |
20080315634 | Motor Vehicle Seat Provided with an Air Supply Device - A motor vehicle seat, in particular for an open motorcar, having an air supply device for supplying an air flow from an air output opening to the head, neck and shoulder area of a passenger. The air supply device includes a heating or cooling system for heating or cooling the air flow. This air supply device is a more efficient heating or cooling system for a motor vehicle seat. For this purpose, the air supply device comprises a sandwich that includes at least one heating or cooling layer and at least one air penetrable layer and a structure which makes it possible to convert the air flow into turbulent or diffused steam. | 12-25-2008 |
20090008970 | Backrest For A Motor Vehicle Seat With An Air Supply Device - A backrest for a motor vehicle seat is described. The rear side of the seat is covered by a planar lining part within which an air supply device for supplying the head, shoulder and neck region of a seat occupant with an airflow is integrated. The air supply device comprises a housing. Fitted together from at least two housing parts, with one of these housing parts being directly supported by the lining part of the backrest. | 01-08-2009 |
20090028534 | Device for Heating an Air Stream in a Motor Vehicle - A heating device for heating an air stream in a motor vehicle has at least one heating layer, preferably consisting of electrically heatable material, and at least one air-throughflow layer through which the air stream can pass. The air-throughflow layer has a structure by which the air stream can be converted into a turbulent or diffuse flow. For this purpose, the structure of the air-throughflow layer preferably has a multiplicity of spacer threads, webs and wires, or the like. | 01-29-2009 |
20090066122 | Vehicle seat - A vehicle seat, in particular a rear seat, has a backrest with a backrest cushion having a ventilation layer through which air can flood, and with at least one ventilator for ventilating the cushion. The ventilator sucks up air from the rear space of the backrest cushion and blows it into the ventilation layer. The ventilation layer is divided into a lower and upper section by an air barrier running in the transverse direction of the seat. At least one ventilator is assigned to the lower section of the ventilation layer and at least one further ventilator with an air-conveying direction the other way around with respect to the air-conveying direction of the first ventilator is assigned to the upper section of the ventilation layer. | 03-12-2009 |
20090134677 | Motor Vehicle Seat with an Air Supply Device - In a motor vehicle seat for a closed motor vehicle, an air supply device is provided for supplying the head, neck and shoulder region of the seat occupant with warm air that can emerge via an air discharge opening on that side of the backrest which faces the seat occupant. In order to surround the head, neck and shoulder region of the seat occupant with a draft-free and inconspicuous air cushion or air space, an air discharge opening that extends at least over approximately one third of the width of the backrest of the vehicle seat is provided. | 05-28-2009 |
20090302646 | Cushion for a Vehicle Seat - A cushion for a vehicle seat has a cushion layer arrangement that is covered by a cushion cover. The cushion layer arrangement includes an air-conducting cushion layer into which air can enter via at least one air inlet and from which the air, after flowing through it, can exit via at least one air outlet which is assigned at least one air outlet opening. At least one air outlet opening is arranged within the cushion cover. | 12-10-2009 |
20110115263 | Motor vehicle comprising a vehicle seat - A motor vehicle has a roof which can be opened and a vehicle seat which has an associated air supply device with at least one air outflow opening arranged in the upper region of the seat and via which an airstream can be blown onto the head, shoulder and nape areas of the seat occupant when the roof is open. A heater system for the interior of the motor vehicle being provided. In order to use the air supply device in a universal manner, it is used to heat up the interior during a heating phase. | 05-19-2011 |
