| Description
| - Trend and effort of the current car seat development is a weight reduction of the individual parts. The development is also focused on the low energy usage, especially recycled materials. The emphasis is placed mainly on the compensation of the comfort layers. which are usually made of polyurethane foam (PUF). The PUF is mostly produced from the oil. Therefore its replacement with suitable material can secure not only weight and energy reduction. but it can also bring an improvement of some mechanical parameters and passenger security. Systematic research led to the testing and comparison of the selected samples from non polyurethane material (NPU) and PU foam for determination of the dissipated mechanical energy which is equal to the area between loading and unloading strain-stress curves. From the measurement results the suitable material for the construction of comfort layer was chosen. This material was textile with horizontally laid fibers. For a comparison of dynamic characteristics, especially transmissibility, an experimental device for testing of complete car seats was developed. Also the virtual models of car seats in finite element method were assembled for achieving of non-measureable properties. The cushion made of the NPU has improved damping and significantly lowered the dependence of the damping factor on the frequency change and the strain rate, when compared to PUP. It is very important for the safety during the car crash, because then the stiffness does not increase significantly.
