Title: Solutions for increasing the comfort in road vehicles based on improving the construction of the seats
Keywords: Comfort, road vehicles, vibrations, lateral acceleration, child tilting seat

Abstract: To reduce the harmful vibrations to which passengers and drivers are exposed when traveling in road vehicles, various suspension systems for the vehicle, chassis or seats may be used. Most research and development is focused on reducing vertical vibrations. When the vehicle is cornering, lateral acceleration occurs, which causes discomfort to passengers. According to a number of studies, the value of lateral acceleration can be reduced if the vehicle or seats lean towards the center of the turn. This study looks at some solutions to increase comfort in road vehicles based on improving the design of the seats. New design solutions for a child tilting seat, which were developed by the authors, are presented. Road experiments have been carried out to demonstrate that the use of these seats when the vehicle is cornering can reduce the value of lateral acceleration.
