    This project presents the need to introduce an emergency disassembly system in the seats of interprovincial buses. Because, if a bus has an accident or overturns, there are no emergency stretchers that can cover all the injured passengers and take them to the medical center immediately. First, information was collected for the development of the finite element analysis and the acceptance and rejection criteria according to the NTE INEN 2708 standard, under which the analyses were carried out. Subsequently, the structure was designed, considering the design parameters according to the regulations in force. Then the simulation was carried out with a series of finite element tests of the seat structure considering the different degrees of inclination and the displacements suffered in each one were observed, in addition, to verify its resistance, to provide reliability at the time of the presentation of the prototype, the data obtained in the different tests were recorded and compared with the requirement values of the current regulations in order to support the quality and safety, and thus facilitate the construction. Finally, the technical drawings were drawn up and the seat structure was built together with the emergency disassembly system and its operation was verified. This project aimed to facilitate the rescue of passengers injured in a bus accident and to reduce the assistance time of the emergency services, which would increase the survival rate of the injured passengers.

    Análisis mediante el método de elementos finitos del ensayo estático según la norma INEN 2708 de la estructura del asiento de transporte público interprovincial para verificar su conformidad en la empresa Sistemas de Asientos American
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2016) Astudillo Bautista, Fausto Sebastian; Arroba Arroba, César Hernán
    In the seating industry passenger bus in the country the process of construction of the structure of the seats is done by hand because there are no studies on the strength of the structure is reflected, and most producers already have their model defined and shaped, that is where the implementation of the rules NTE INEN 2708 as it focuses not comply with those rules. In this study the mechanical properties of the materials were determined by uniaxial tensile test of materials constituting the structure of the two seat models which are manufactured in the company Seat System AMERICAN with the finite element method the resistance was found of the whole seat structure applying loads at different positions and heights as indicated by the standard INEN NTE 2708 in appendix 12. After simulating the seat strength it was found that the seat resists all the time of application of the load thus fulfilling the Ecuadorian NTE INEN 2708 standard.
