The seat adjustments of general luxury car brands are all on the door. For example, Mercedes-Benz S-Class, Audi A8, BMW 7 Series and so on. In order to improve the riding experience of the occupants of these cars, the seat adjustment is designed on the door of the car.
Every car seat is equipped with a very important thing - the headrest. The headrest is one of the safety configurations of a vehicle. Most of the models currently on the market are equipped with headrests on all seat positions. The biggest function of the headrest is to protect the safety of the neck during rear-end collisions, because If there is no headrest, the head will not have any support in the event of a rear-end collision, and the head will suddenly fall back due to inertia, which may cause serious neck injuries. The headrest also plays a role in slowing down the impact on the head. In addition, the headrest also has the function of breaking the window. When the vehicle falls into the water and cannot open the door, the telescopic rod on the headrest can be used to escape through the window.
