they will hit the windshield and hurt their head
In a 15 mph crash without a seatbelt, the crash test dummy would experience the full force of the impact which could result in injuries such as head trauma, whiplash, or broken bones. Without the seatbelt to restrain the dummy's movement, it may also be thrown forward or out of the vehicle, increasing the risk of serious harm or death.
Yes, but the impact would have to be so hard that you would definitely be killed without it anyway.
Yes, unless you are "T" Boned (hit hard in the drivers door).

No, when the body stops moving in a crash, the organs inside the body may still be subjected to forces that can cause injury. The sudden deceleration can lead to damage to organs due to their inertia and movement within the body. This is why wearing a seatbelt is important to minimize these forces during a crash.
During a car crash, the crash dummy experiences several forces including inertia, impact force, and compression forces. Inertia causes the dummy to resist changes in motion, the impact force from the collision can cause acceleration or deceleration, while compression forces can result from the dummy hitting the seatbelt or airbag.
In a 30 mph crash without a seatbelt, the force experienced by a person can be substantial, as the body continues moving forward at that speed until it collides with an object, like the steering wheel or dashboard. The force of impact can be estimated using Newton's second law (F=ma), where the acceleration is determined by the deceleration over a very short distance. This can result in forces multiple times the person's body weight, leading to severe injuries or fatalities. The absence of a seatbelt significantly increases the risk of such outcomes.

I was actually in a rollover car accident in 2009. It was a suburban and there were 6 kids in it, including me and I was the only not wearing a seatbelt. Everyone survived and my mom got the worst, her arm was ripped to shreds. But I got out with only a couple scratches on my arm. I think my case was just lucky. I don't think it is likely for someone to survive a car crash without a seatbelt in general.
true In A crash test using real live people, Where A bridge collapsed , Everyone who had their seatbelt on drowned.
It keeps them from being ejected from the vehicle.
small explosive device inside seatbelt receiver. when crash sensor ges off it fires the explosive inside receiver and pulls or "pretensions" the seatbelt.
