Abstract
Se proporciona un sistema de carcasa con volumen para sujeción expandible e híbrido, que incorpora por lo menos una superficie de reacción con el cuerpo humano semirrígida y desplegable. Una o más paredes del volumen expandible son sustancialmente plegables y se fijan a un extremo de una base de montaje que puede fijarse a una pieza estructural de un vehículo y otro extremo se fija a una superficie de reacción desplegable y semirrígida. La pieza de expansión con absorción de energía puede ser de paredes delgadas o similar a una membrana y constituirse de goma plegable, plástico o una tela tejida. Los métodos para fijar una pieza de expansión flexible a una superficie de contacto semirrígida o una pared de expansión semirrígida de la carcasa incluyen proporcionar una fijación mecánica al atrapar el borde de la pieza de expansión entre un bastidor y una pieza semirrígida. El material de una pieza semirrígida moldeada puede fluir sobre o en las geometrías proporcionadas en una pieza de expansión flexible para unirse. Un contacto puede definirse mediante moldeado por mezcla para convertir diferente rigidez del material.
