摘要： Disclosed are a method and a device for determining the sitting comfort of a seat cushion, which is perceived by a person during sitting, especially the perceived softness of a seat in a motor vehicle. According to the invention, the pressure distribution of the seating surface is measured during sitting via a pressure-sensing mechanism, the actual deformation of the seating surface during sitting is measured by means of a distance-sensing or deformation-sensing mechanism, and a value of the sitting comfort during sitting is calculated from the measured, actual deformation and the measured pressure distribution of the seat cushion.

摘要： The invention relates to a method for determining an evaluation figure which is representative of the quality of the dynamic seating comfort of the seat padding of a vehicle seat. To this end, a flexible measuring mat is placed on the seat padding in such a way that it is defined in position, a surface-covering matrix of force measuring sensors operating without hysteresis being integrated into the same. A test person or a test body behaving in an anthropomorphous manner in terms of oscillations is positioned on the thus prepared vehicle seat in a position-defined manner, and is loaded in a manner which is close to reality. For the measurement, said body/seat system is preferably stimulated for the oscillation, preferably in the assembled state in the corresponding vehicles, e.g. by travelling over a bad stretch of road, whereby the signals delivered from the force measuring sensors are added in phase to form a global signal. The frequency characteristic of the body/seat system is determined on the basis of said global signal, and the surface integral of said frequency characteristic is determined up to a certain end frequency. The value of said surface integral is used as an evaluation figure of the dynamic seating comfort of the seat padding of the vehicle seat.

摘要： The invention relates to an air supply mechanism for a vehicle seat (12) and a method for operating the same. Said air supply mechanism comprises a control device (24) for triggering a fan (38) and a heating element (39) that is mounted downstream of said fan (38). The control device (24) switches on a heating element (39) while controlling the start of a fan (38) when the air supply mechanism is turned on such that the fan (38) is started and is operated at the minimum ventilator speed during a predetermined period of time before the ventilator speed is increased to a predetermined operating point and the ventilator speed is then regulated according to the speed of travel, thus providing a seat occupant with a pleasant sense of warmth immediately after the air supply mechanism is turned on rather than an initial feeling of a draft as a result of relatively cold air that is discharged.

摘要： The invention relates to an air supplying device for a seat (12) of an open-top vehicle. Said device comprises at least one air outflow opening (18) provided in the upper region of the vehicle seat, by which means the head, shoulder and neck area of the occupant of the seat can be exposed to an air flow (L) in order to reduce undesired draughts. Said air flow can be regulated by means of a control device (24). The aim of the invention is to improve the comfort of the occupant of the seat during open-top driving. To this end, when the air supplying device is switched on, the air flow is regulated to an allocated basic value (G1-G3) by means of the control device (24), according to an automatically detected external parameter or a set value which can be selected by the occupant of the seat. The air flow (L) is then readjusted according to another automatically detected parameter value.

摘要： The invention relates to a cushion with a cushion core, particularly made of a foam material, and with an air- and moisture-permeable covering layer that encloses said core. The aim of the invention is to improve the climate comfort by effecting a good removal of moisture from the intermediate area between the covering layer and the cushion core. To this end, interspaced longitudinal and transversal grooves are shaped into the surface of the cushion core that is covered by the covering layer. These grooves are open up to the covering layer and intersect one another. In addition, the cushion core is provided with channels that pass through the entire thickness of the core. Said channels lead to the points of intersection of the longitudinal and transversal grooves as well as to the exterior of the cushion core.

摘要： The invention relates to a heating device for heating an airflow, in particular, for a motor vehicle, comprising at least one heating layer (14), preferably made from an electrically-heated material and at least one air-permeable layer (10, 12), through which the airflow can pass. According to the invention, a heating device with improved efficiency can be achieved whereby the air-permeable layer (10, 12) comprises a structure by means of which the airflow may be transformed into a turbulent or diffuse flow. The structure of the air-permeable layer (10, 12) hence preferably comprises a number of spacer threads, spacer webs and spacer wires, or similar.

摘要： The invention relates to an air supply mechanism for a vehicle seat (12) and a method for operating the same. Said air supply mechanism comprises a control device (24) for triggering a fan (38) and a heating element (39) that is mounted downstream of said fan (38). The control device (24) causes a heating element (39) to be preconditioned when the vehicle is unlocked, a vehicle door is opened, and/or a soft top switch for opening the soft top is/are actuated. The control device (24) ends the preconditioning process while turning on the heating element (39) and the fan (38) when a switching-on signal for the air supply mechanism is provided. The heating element (39) and the fan (38) are then regulated by the control device (24) according to the speed and the outside temperature, thus providing a seat occupant with a pleasant sense of warmth immediately after the air supply mechanism is turned on rather than an initial draft or a delayed switching-on reaction.

摘要： The invention relates to an air supply device for a motor vehicle seat, in addition to a method for the operation thereof. The air supply device for a motor vehicle seat (12) comprises an air outlet opening (18) which is provided in the upper area of the motor vehicle seat (12), by which means the head, the shoulder and the neck area of the occupant of the seat can be exposed to an air flow (L) in order to reduce undesired draughts. The air flow (L) can be controlled by means of a control device (24) by controlling the rotational frequency of the air (n) of a fan (38) and can be warmed by a heating element (39). The heating element (39) is characterised by three heating steps which can be selected by manually adjusting a control device (26) by the occupant of the seat by selecting a heating step and/or by the control device (24) corresponding to an external parameter value. The control device (24) can control the rotational frequency of the air (n) of the fan (38) corresponding to an additional external parameter value. Due to the construction of the inventive air supply device, the heat sensitivity of the occupant of the seat can be taken into account during the removal of areas sensitive to draught.

摘要： The invention relates to a motor vehicle seat having an air supply device (42) by means of which a ventilation layer (24) of the cushion (18) of the seat can be flown through by an airflow in order to ventilate the seat and/or to heat the seat. The motor vehicle seat also comprises an air outflow opening (16) of the air supply device (42), which is located in the upper area of the seat and via which the head area, shoulder area and the back of the neck area of the seat occupant can be exposed to an airflow. To this end, a fan (40) is assigned to the air supply device (42). In order to create a motor vehicle seat with a universally installable air supply device, the fan can be supplied with air from the ventilation layer (24) of the cushion (18) of the seat in order to produce the airflow for the head area, shoulder area and the back of the neck area of the seat occupant.
