Abstract: More and more attention has been paid to the safety of automobiles, and regulations and various automobile safety evaluation institutions have also put forward higher and higher requirements for vehicle safety. For occupant protection, the current general evaluation indicators in the industry focus on measuring the first and second row passenger protection. In order to highlight the all-round occupant protection, some automobile companies have developed rear window airbags for the three-row occupants unique to the 6-seat and 7-seat models. Based on the development of the rear windshield airbag subsystem of a certain vehicle, this paper formulates the evaluation benchmark of the subsystem, sorts out the problems in the rear windshield airbag layout, matching with interior trim (hatchback door trim panel, ceiling, seat), and the airbag point explosion process, as well as the solutions, so as to provide certain references for the subsequent large-scale development and application of the rear windshield air curtain.
