ABSTRACT
The article presents the results of research on the assessment of vibrational comfort of children carried in child seats. The work analyzes the impact of the child's mass and the speed of the car passing through the speed bump on the level of vibration to which the passenger (child) transported in the child seat mounted on the rear seat of the car is exposed. The tested car seats were installed in a passenger car using the ISOfix base. During the tests, the measured values were the acceleration of the seat child seat, the backrest of the child seat, the rear seat of the car and the child seat ISOfix base. As part of the research, car drive through the speed bump were carried out at different car speeds and with different mass simulating the mass of a child. The test results were analyzed in order to determine the magnitude of vibrations generated during car drive through the speed bump. Based on the results obtained, the level of vibrational comfort of a child trip in a child seat was assessed.
