Is the force of a car window closing on a head strong?

The force of a car window closing on a head is very strong and can cause injury. Here are specific details about the automatic window roll-up feature: High-end models: When purchasing a car, you may notice that some high-end models come with an automatic window roll-up option. According to feedback, this feature is very convenient in daily use, saving effort and making it easier to close and open windows. However, because it is automatic, there may be concerns about safety. Anti-pinch function: Car windows are equipped with an anti-pinch function. According to the European EEC standard, the window will activate this function when encountering a resistance of 100 newtons in the anti-pinch zone. Caution with children: Whether it's a sedan or an SUV, if there are children in the car, extra caution is needed. SUV owners, in particular, should not leave children alone in the back seat and should ensure the child lock is engaged to prevent accidental activation of the window switch.
I've driven various car models and found that modern electric windows are usually equipped with anti-pinch features, which automatically stop or reverse when resistance is detected, without exerting excessive force. This relies on torque sensors monitoring current changes, reacting when encountering objects like heads to prevent serious injuries. National standards mandate this mechanism in new vehicles to prevent accidental pinching of children or pets. However, older models lack this feature, and when the motor operates at full speed, the force can indeed be significant, theoretically capable of causing fractures or contusions. For daily use, I recommend testing the anti-pinch function by placing a soft object to ensure a safe and proper response. If malfunctions occur, such as sensor failure or unstable voltage, it's best to seek repairs promptly rather than risk inspection.
