Analysis of the impact of a child seat mounting method on vertical vibrations affecting a child in a child seat

The article presents the results of research on the impact of mounting a child seat on vertical vibration courses when driving a Vehicle by the release speed bump. The work analyzes the influence of the child’s mass and the speed of driving a Vehicle by the release speed bump on the course of vertical vibrations. The tested child seats were mounted rearward-facing on the rear seat of a passenger vehicle. The child seat A was fastened with an isofix base, while the child seat B was fastened with standard car seat belts. During the tests, the measured values were acceleration seat of child seats, vehicle rear seat and ISOfix base. As part of the research, crossings at the speed bump were carried out at different speeds and with different mass simulating the mass of the child. The test results were analyzed in order to determine the magnitude of vibrations generated during passing through the speed bump. Based on the results obtained, an assessment of the intensity of vibration transfer was made.
