As a part of vehicle structure, the windshield is a critical to proper airbag deployment. In a crash, an improperly installed windshield may cause an airbag to deploy too early or too late. In either case, the safety of the occupants may be greatly compromised. On impact the windshield acts as a brace to support the passenger side airbag. If the windshield separates, the airbag does not have a constrained space, and it is not effective in protecting the occupants of the vehicle.Structural Integrity
The windshield is an important part of a vehicle's energy management system, which directs crash energy around the vehicle compartment. If the windshield is improperly installed, the vehicle may crumple differently than the manufacturer intended, jeopardizing its occupants.
