What is the term for the area of impact when a person strikes a windshield with their body?

• A. Area of impact
• B. Point of impact
• C. Contact area
• D. Impact zone

Answer: (A)

In crash analysis, the area of impact refers to the region of the windshield that receives contact and energy transfer when a person strikes it. When the body–often the head or face–presses against the windshield, the force isn’t confined to a single pinpoint location. The curved surface and the body's shape cause the contact to spread over a patch, whose size and shape depend on posture, part of the body involved, and deformation of the windshield. This patch is the area of impact, and it matters because it relates to how the load is distributed and what injuries might occur. The other terms describe either a single point of contact, a broader patch not specifically tied to the windshield, or a general region of influence, which isn’t as precise for this scenario.
