Whether it's a short trip or a medium or long distance trip
I believe for many people
Just drive or take a little longer
It's all exhausting
So some people "open their minds"
Flatten the passenger seat in the car
Sleep directly while the vehicle is on the move
caution! caution! caution!
If this is done while the vehicle is on the move
Personal safety can be said to be unsecured

Fastening the seat belt like this = no protection
The common "three-point seat belt" on the car should keep the shoulder strap across the chest cavity, the belt close to the hip bone, and at the same time be able to withstand normal force to ensure the safety of passengers.
If the seat is flattened, because the lower half of the seat belt is basically parallel to the body, it will not be able to receive normal force, and the upper half of the seat belt that was originally diagonally worn on the chest has also been suspended, and the two stress points of the seat belt have been changed.
From a safety perspective
Passengers in the passenger seat do so while driving
It can be said that it is full of dangers
Sit in one position
Recline the seat with your feet resting on the centre console
Such a riding posture, once the vehicle encounters an emergency or a frontal collision, under the action of inertia, the body will lean forward, and the legs will be squeezed in the direction of the body due to the placement too high, the whole person's body is like a V-shape, the waist will withstand a huge impact, such as an accident, may cause the waist to break.
Sitting posture two
Lay flat on the seat and lie down completely
If the angle between the seat back and the chassis is too large, or even directly flat, once a collision or rear-end collision occurs, the whole person will slide forward, the protective effect of the seat belt will no longer exist, at this time the passenger's knee will bear the brunt, it is difficult to imagine how much impact the leg will be affected.
In addition, take the bus in the back seat
If you choose to lie flat, there is no security protection
The human body may collide with the front seat
It can even get stuck in the voids of the front and rear seats
The role of seat belts is
When the car encounters an unexpected situation emergency braking
Ability to tie passengers to their seats
So as not to suffer secondary injuries in the forward charge
Therefore, the fastening method of seat belts must be mastered
The shoulder straps are tied under the armpits, and it is not possible to install the buckle at will
In general, whether it is the driver or the passenger
Regardless of whether you sit in the front row or the back row, you must fasten your seat belt
Minors under the age of 12
Passenger seats are not permitted
A child-only seat belt is required
