“…The group of (100-150) cm vehicle seats are the last child vehicle seats. Children, instead of using the inner belts of a child seat, can already use standard seat belts placed in a passenger vehicle [20]. In addition, the seats of this group have the ability to adjust not only the backrest but also the headrest, thanks to which they grow with the child.…”

The selection of a child seat is not an easy task for future parents. Information about child seats, assembly methods, usability and prices affect the purchasing preferences of parents or legal guardians of children. The article contains information about the factors to pay attention to when buying a child seat. The main purpose of the article is to analyze and evaluate information on the selection of a vehicle seat for the right passenger vehicle and child. The article discusses information about the ADAC child seat crash test and the plus test, which are mainly performed for rear-facing child seats.The article presents information on groups of child seats and the method of their installation in a passenger vehicle. The purchasing predispositions of parents and legal guardians in terms of the selection of a child seat were also described. It should be noted that most respondents pay attention to the level of safety of child seats than to their price.

“…The issues of vibrational comfort of adults have been discussed in many normative documents [42][43][44] The standards also describe the measures of the influence of vertical vibrations on a person in a sitting position There are no such standards for children in child seats [42][43][44][45][46][47]. The development of safety seats should go hand in hand with the development of vibration comfort [48][49][50]. The study in [51] presents the results of vibration tests carried out with the use of two child seats while driving on roads with different surfaces.…”

This paper deals with the issues of the impact of vertical vibrations on a child seated in a child seat during a journey. Its purpose was to assess the impact of fastening the child seats and road conditions on the level of vibrations recorded on child seats. The paper describes the tested child seats, the methodology of the tests and the test apparatus included in the measuring track. The tests were carried out in real road conditions where the child seats were located on the rear seat of a passenger vehicle. One was attached with standard seat belts, and the other with the ISOFIX base. When driving on roads with three types of surface, the following vertical accelerations were measured: seat of the child seats, the rear seat of the vehicle and the ISOfix base. The recorded accelerations were first analyzed in the time domain and then in the frequency domain. Three indexes (r.m.s, rmq and VDV) were used to assess the vibration comfort. Research has shown that the classic method of fastening a child seat with standard seat belts is more advantageous in terms of vibration comfort. Calculated indicators confirmed the negative impact of separating the child seat from the rear seat of the vehicle using the IQ ISOFIX base.

The article presents the results of laboratory and road tests of the impact of the method of fastening child seats on the vibration comfort of children transported in them. The tested child seats were mounted facing the direction of travel on the rear seat of a passenger vehicle. Two child seats were used in the work, the first (red) was attached to the rear seat behind the driver’s seat using the ISOFIX base. The second child seat (grey) is attached to the rear seat behind the passenger seat with standard seat belts. During the measurements, the child seats were loaded with the mass of 5 kg, 10 kg and 15 kg, simulating the mass of a child fastened in a child seat. The child seats used can be mounted both forward and rearward facing. In the conducted research, they were installed in a passenger vehicle facing the direction of travel. Laboratory and road tests based on registered vertical accelerations showed a negative impact of using the ISOFIX base in terms of vibration comfort.
