Real stress arising in the backrest frame of a car seat

Original language description

At present lot of people spend still more of their life on the road. Vehicles have been becoming ever more sophisticated and the main direction of their development is placed primarily into the areas of environment, design, safety and comfort. The main current trend with regard to the environment, reducing emissions, fuel economy etc. is reduction of vehicle weight. A large amount of manufacturers and research works is concerned on a reduction of the weight of individual vehicle components primarily by application of unconventional materials. We've been finding highly sophisticated composite material which by targeted influencing of their properties can replace conventional steel materials with considerable weight reduction. As a long-time neglected part in this area we can generally mark the steel frames of car seats, especially their big mass which reduction can be a good challenge in future optimizations. In this work based on experiments with the normalized loading and numerical simulations we found how big stress and strain arise in the frame and especially their distribution. The experiment was based on loading of the back rest with a controlled torque relative to the R point of the seat. The overall deformation was monitored with using a laser and local deformation using strain gages. For a more detailed description of the emerging stresses, primarily about their distributions and directions a quasi static numerical model has been created. The found results will be applied mainly for the future construction of a composite backrest.
