The invention discloses an automobile seat headrest case with a lifesaving function and relates to an automobile occupant lifesaving apparatus. The automobile seat headrest case with the lifesaving function is mainly structurally characterized in that a headrest case sleeves an automobile seat headrest, a left
air chamber and a right
air chamber are respectively fixed at the two sides of the headrest case, a gas tank is fixed at the side portion of the headrest case, a gas outlet of the gas tank is provided with an air valve, an air outlet of the air valve is connected with a gas distribution head, the gas distribution head is provided with three air outlets, two of the air outlets are respectively sealed and connected with one end of a left
pneumatic tube and one end of a right
pneumatic tube, the other ends of the left
pneumatic tube and the right pneumatic tube are respectively sealed and connected with air inlets of the left
air chamber and the right air chamber, and the other air outlet of the gas distribution head communicates with an
oxygen face shield through a
face shield pneumatic tube. The gas tank stores high-pressure medical
oxygen, when there is a water penetration accident, a user wears the apparatus, a switch is switched on to aerate the left air chamber and the right air chamber, at the same time, the user breathe in the water by use of the
breathing face shield, and thus the purpose of lifesaving is realized.
