Abstract

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.
