Problems and design of a powered mechanism-based car child restraint system

Vehicle collisions can cause serious injury or even death to passengers, especially children aged 1–12 years. Hence, child restraint systems are now subject to legislative requirements for the development of better solutions. This paper presents an innovative design for a car seat mechanism, which fills the gap in existing solutions referring specifically to protecting children from the impact of accidents. The proposed mechanism deploys in 5 s in the design for children from 75 to 150 cm and up to 36 kg, approximately from 1 to 12 years of age. The mechanism lifts and rotates at a time of 0.1 s for unexpected situations, such as a vehicle crash. The design of the seat mechanism for a child restraint system has been developed in terms of kinematic analysis to corroborate the correct displacement and force analysis to find the forces applied to the mechanism by an actuator to move the mechanism by simulation. In accordance with the requirements of the European Commission. This article suggests that folding seat mechanisms are innovative and practical. The potential awaits further research to better protect children in crashes.
