Vehicles sold in many countries around the globe must comply with ECE R14 or FMVSS 210 regulation in order to ensure proper function of the safety belt system when submitted to high loads. In these regulations, the procedure requests to apply high forces on the safety belts by using proper devices. All components of the system such as seats, safety belts, anchorage points and vehicle body have to resist the specified loads with no damages. The loads are applied slowly and sustained over a long period of time, characterizing a quasi-static test. The present work was developed to understand the energy distribution among all components during seat anchorage test and determine any potential failure, including cases in which components are changed. The system was optimized considering the energy dispersed by each component and their material plastic strength limit.

In vehicle design, the H point is a theoretical relative location measured in relation to specific characteristics, for example, H point to vehicle floor (H30), H point to ground (H5) and others. Based on theoretical H point automakers concept their vehicle and have to make important decisions on vehicle architectural that could result in a bad product for the future customers and during the early phase of vehicle development, one of the key design attributes to consider is in relation to the comfort of the user, so that its design and its components enable a favorable interaction with the occupant. Accessibility is one of the pillars on which this concern can be observed. Certain features such as the size of door opening and the height of the vehicle from the ground, among others, may influence the level of satisfaction of the occupants’ access.
