Impact absorbing device of the type made up of pneumatic chambers designed to protect fragile elements such as calculators, electronic plates (circuits), measuring instruments, remote controls and a the similar ones. It consists of a first impact absorbing chamber at the bottom and a top flexible cover that rests on the mentioned first chamber. The chambers can be inflated through an entrance valve for exterior air, carbon dioxide gas, or gases generated through a chemical reaction produced by reacting elements contained inside the first chamber. The top flexible cover can have a Velcro(R) type clasp or similar. It gets a perfect filling and therefore the pressure of the mentioned chambers on the protected element due to the fact that the hole or perforation for the gas to go into the second chamber is placed on the opposite side to the ingoing perforation of the first chamber or, correspondingly, from the place where the gases are generated; which will fill the impact absorbing chambers.
