The invention discloses an airbag testing apparatus. The apparatus includes a pedestal, a testing case with a top open, a timer, a pressing assembly, a plurality of pressure sensors, a single chip microcomputer and a starting button. The testing case with the top open is mounted at the pedestal. The timer is mounted at the testing case with the top open and is intended for performing timing. The pressing assembly includes a pressing rod which conducts telescopic movement under the driving of a first motor and a pressing block which is disposed at the bottom end of the pressing rod. The plurality of pressure sensors are separately mounted at the bottom surface of the pressing block and the bottom surface of the testing case with the top open. The starting button is connected to a control end of the single chip microcomputer. An input end of the single chip microcomputer is connected to the pressure sensors. A data transmission end of the timer is connected to a data transmission end of the singe chip microcomputer. According to the invention, the apparatus can test the sealing properties of an airbag and the rigidity of the air bag, has high testing precision, and is easy to operate.
