Normative Requirements for Automotive Restraint Systems
Kučera, Jonáš ; Dadák, Leo (referee) ; Rochla, Tomáš (advisor)
This diploma thesis deals with the normative requirements on the activities of restraint systems. It includes biomechanical limits of the human body, restraint systems, description of the principle of their action and legislation. Legislation, particularly regulations of ECE and EC directives defines the normative requirements on the activity of restraint systems in the context of the approval process. There are described two types of restraint systems: seat belts and airbags in details. There are created simulations of crashtests and reviewed influence of using restraint systems on elimination of negative phenomenon of car accidents.

Vehicle Passive Safety Systems
Jelínek, Adam ; Rozsíval, Jan (referee) ; Blaťák, Ondřej (advisor)
This bachelor’s thesis of research nature deals with detailed description of passive safety features in modern cars and with characterization of these features in relation to electric and autonomous cars. Detailed structural and material description of car’s crumple zones and safety cage with description of car’s restraint systems is supplemented with historic background on development of these features. Final part of thesis gives reader an idea of application and necessary changes of these features when used on electric or autonomous cars.

Design of strain gauge devices for safety belts load measuring
Lontras, Martin ; Jebáček, Ivo (referee) ; Mališ, Michal (advisor)
The aim of this thesis is to design, produce and experimentally verified measuring device for measuring force in seatbelt, by using strain gages. First are discussed possibilities of measuring force by using device placed in between two parts of seat belt or in anchor point. These suggestions were not accepted for various reasons. Therefore is further described girder, which belt slightly deflected so that part of the load is transferred to the strain gauge measuring element. As default concept is choosen aluminum U-profile, in which is placed measuring mechanism. There are performed calculations of basic geometry and stress control. Then is described manufacturing and calibration on universal testing machine. In conclusion is realized measuring of the force in seat belt, which is loaded by shock force, occasioned by dropping weights from a certain height, which simulates the behavior of the belt and gauge during a crash test.

Comfort and Safety
Ševčík, Pavel ; Mikulčík, Aleš (referee) ; Hájek, Vítězslav (advisor)
This bachelor’s thesis considers by safety and comfort systems in motor vehicles. Is concentrate to safety systems for example seat belts and tighteners, airbags and their separations and about direct units for activation safety systems. Next about system of active head rest and about safety transport of children in cars. Deal with comfort systems and shortly discuss about trend of safety systems. The last part of bachelor’s thesis considers of analyse and experimental measurement of dump sensor. Function of accelerometer ADXL150 is described and the practical measurement is made with including evaluation of measured results.

Vývoj aktivních a pasivních bezpečnostních prvků osobních automobilů
Kubín, Tomáš
In my bachelor thesis I deal with issues of active and passive safety of cars. In the introductory part I deal with the historical development of the safety of motor vehicles and the basic division of security elements. In the second part I present requirements for compliance with homologation regulations in the field of vehicle safety. In the next part the bachelor thesis focuses on the current elements of active and passive security. In the last part of my work, I describe the trends in passive safety of cars.
