This work is devoted to testing the strength characteristics of a car seat by modeling test conditions of certificated test ECE R14. Tasks that were solved during the research: 1. Description of the model and test conditions 2. Assembling of the chair by finite element method 3. ECE R14 certification test 4. Improving the initial test-based model Calculations were performed in the LS-Dyna program, which clearly shows the ability of the car seat to withstand the applied loads. The analysis was carried out by the finite element modeling method. The result was an improved model of a car seat that meets European current standards.
