METHOD FOR THE QUANTITATIVE DETERMINATION OF THE DYNAMIC SEATING COMFORT OF A SEAT PADDING |
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. |
