For the evaluation of seats under comfort and health aspects by means of a Finite-Element (FE) simulation a detailed static and dynamic occupant model is required. The occupant model CASIMIR, which is presented here, in combination with seat model was used in different comfort simulation projects where a good correlation to measurements - seat pressure distribution and transfer function - was found.In order to increase the accuracy of results for internal quantities e.g. the load on the intervertebral disks, CASIMIR was enhanced to improve the force transmission from the seat to the human body. Due to the consideration of the different tissues by corresponding material parameters and the modelling of the filamentary force transmission via springs and dampers for muscles, the human anatomy is modelled more realistically.
