When you open the windows of your car, you may have noticed that the window in the back does not roll down all the way like in the front. Without necessarily finding the right explanation… Here it is!
It’s hot, and since the air conditioning in a car doesn’t only have good sides (higher consumption, risk of catching a cold, etc.), the best way to cool off is sometimes to simply open the windows. With the speed, the air will be able to circulate widely and cool the sometimes hot passenger compartment, especially if your vehicle has been parked for a long time in direct sunlight.
You have probably already noticed that the windows of a car do not all open in the same way. If the front ones ”disappear” completely in the slot provided for this purpose, the rear windows never lower completely. At the rear, five to ten centimeters of tempered glass – used to make the side windows and the rear windshield – still protrude from the door. But why ?
If you think about it for a moment, the answer seems obvious: security. As children most often occupy the rear seats in a car, leaving a piece of window protruding provides additional protection between the inside and the outside of the vehicle. Thus, for example, it is more difficult for a young boy or a young girl to let his arm protrude through the window, which can actually be dangerous. However, there is another explanation that simply answers a technical problem.
To understand, just look at a car in profile. You will find that the rear doors are almost always narrower at the bottom than the front doors. For what ? Because at the rear of the vehicle the bodywork is most often cut out so as to go around the wheels. In fact, the windows do not have enough space in the door to be able to descend completely without encroaching on the wheel arch. Some models were thus completely deprived of opening due to the design of the car. This was the case recently for the DS4 or the Citroën C4 Cactus, especially for a question of cost. If your child asks you about the next holiday route, you will now have a good answer for them!
