摘要： A seat testing punch is provided with an upholstered pressure element that can be used as a suitable aid in comfort comparison testing of different test seats to be performed according to strict test criteria, with which seat testing punch various test seats can be loaded in a realistic and reproducible manner as often or for as long as desired. For this purpose, the shape of the pressure element is made to simulate the pelvis and thighs, including the hip joints, of a human skeleton, at least as regards the underside. The upholstery of the pressure element likewise simulates anthropomorphically the soft parts in the area of the buttocks in terms of local distribution of thickness and softness. In particular, the two sitting pressure points of human buttocks and their immediate environment are simulated as naturally as possible in terms of shape, position, hardness, and local hardness distribution.

摘要： A method and a system for quantitative determination of the seat climate of a seat cushion is provided. For this purpose, the seat surface is subjected, during realistic mechanical loading of the seat cushion to be tested, to a flow of moisture from a climate mat. Any moisture stagnation at the seat surface is measured. For this purpose, the seat cushion, covered with a flexible multilayer climate mat, is loaded realistically via an anthropomorphically shaped seat testing punch. The climate mat consists of the following layers: a plurality of flat moisture sensors; a trouser material layer with low moisture uptake; a distribution layer that is readily permeable to air and has a noncompressible structure; a fleece layer that can be moistened and replaced as the moisture storage medium; an electrically insulating vapor barrier; and an electrically heatable heating mat that can be set to a specific temperature.

摘要： A method and a device for determining the surface contour of an elastic seat cushion deformable under load are provided. Through the use of a measuring mat placed on the seat cushion, after the load is relieved, the resultant deformed state corresponding to the deformed surface of the cushion is preserved by applying a vacuum to the measuring mat. The three-dimensional surface contour of the measuring mat fixed in its deformed state is measured with a multicoordinate measuring device in known fashion. The measuring mat consists of two vacuum-tight material webs, especially plastic films, connected vacuum-tight with one another to form a pocket having a vacuum connection, with the pocket being filled with a granulate, preferably a foam granulate.

摘要： A method for determining an evaluation number which is representative of the quality of the dynamic sitting comfort of upholstered seat elements of a vehicle seat. A flexible measuring mat is applied to the upholstered seat element in a defined position and a matrix, which covers the surface, of force measuring sensors which operate without hysteresis is integrated into said measuring mat. A test person or a test body which behaves anthropomorphically in terms of oscillation is positioned on the vehicle seat. In order to carry out a measurement, this body/seat system is excited so as to oscillate, for example by traveling over a bad stretch of road. The signals supplied by the force measuring sensors are added with the same phase to form a composite signal. The frequency response of the body/seat system is determined from this composite signal.

摘要： A cushioning for a vehicle seat has a cushioning layer and a ventilation layer which covers this cushioning layer and through which air flows. A plurality of air ducts completely penetrate the cushioning layer and are open on the backside of the cushioning layer and in which one miniature fan respectively is arranged for blowing air into the ventilation layer. For ventilating cushioning areas which, because of sitting aids arranged in the cushioning layer, are not suitable for a direct ventilation, the end of the air ducts assigned to these cushioning areas which faces the ventilation layer is constructed such that a portion of the air flow penetrating the air duct enters into the open cross-sectional surface of the ventilation layer.

摘要： A vehicle seat has a cushion integrated in a seat part and/or a backrest, which cushion has a ventilation layer, through which air can flow, and an air-permeable cushion cover spanning the cushion surface. The seat also has at least one ventilator arranged below the cushion for blowing air into the ventilation layer. In order to provide a ventilated vehicle seat construction at reasonable cost for vehicles of the medium to lower price range, the ventilation layer is constructed as an air-permeable cushion support which rests on a cushion carrier only by way of intermediate placement of an air-impermeable pressure distribution layer. The pressure distribution layer has at least one inflow opening for the ventilation air on which the ventilator is arranged below the air distribution layer.

摘要： A seat test body is provided for vibration measurements. In order to be able to obtain, during vibration measurements in the whole spectral range, measuring results which can be compared at least qualitatively with corresponding test person measurements, the buttocks imitation and the back imitation of the seat test body are each formed by padded hard parts. The hard parts of the buttocks imitation and those of the back imitation imitate true to life the corresponding bone structure of a human skeleton at least with respect to the portion of the skeleton which is loaded during sitting. With respect to the layer thickness, the softness, the elasticity and the damping behavior as well as the local distribution of these parameters, the padding of the hard parts anthropomorphically imitates the soft parts in the buttocks area and the back area. For achieving the required sitting weight of the seat test body, a passive ballast in the form of several weights is placed on the interior side into the buttocks imitation and/or is placed on shelf-type consoles on the interior side of the back imitation. Relative to the buttocks imitation, the back imitation is disposed to be swivellable within a limited angular space about the hip joint point and is elastically prestressed in the sense of a stretched position of the back part and the buttocks part.

摘要： A vehicle seat having seat and backrest cushions includes a ventilation device for ventilating the cushions as well as a heating device for heating the cushions. A desirable sitting climate providing high comfort is produced by eliminating both a seat user's perspiration and overcooling. The desirable sitting climate is assured by a control unit which is connected on an input side with a temperature sensor arranged in a cushion and on an output side with the electric circuits of the ventilation unit and the heating unit. The control unit is adjusted such that, at cushion surface temperatures measured by the temperature sensor which are above an indicated value, it switches on the ventilation device or changes it to a higher power stage and/or switches off the heating device or changes it to a lower heating capacity. At cushion surface temperatures which are below the indicated value, the control unit switches off the ventilation device or changes it to a lower power stage and/or switches on the heating device or changes it to a higher power stage. The control unit may also operate based on an output from a moisture sensor.

摘要： A vehicle seat has a cushion integrated into a seat part and/or a seat back. The cushion has a ventilation layer through which air can flow and a cushion cover stretched over the cushion surface facing the seated individual. A plurality of electrically driven miniature fans which are located in air channels to blow air into the ventilation layer that terminate at the underside and rear of the cushion facing away from the cushion cover are provided. The air channels extend up to the ventilation layer. To optimize the ventilation efficiency of the seat ventilation, exhaust air channels are provided in the cushion that extend from the ventilation layer up to the underside or rear of the cushion and terminate freely there.
