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.
