At What Height Should Seat Belts Be Worn?

140cm. Car seat belts are suitable for individuals weighing 36KG and with a height of 140CM or more. More information about seat belts is as follows: 1. Introduction: Car seat belts are safety devices designed to restrain occupants during a collision and prevent secondary collisions with the steering wheel, dashboard, etc., or to avoid injuries caused by being ejected from the vehicle during a crash. 2. Working Principle: The retractor contains a ratchet mechanism. Under normal circumstances, occupants can freely and smoothly pull the webbing from the retractor. However, when the webbing stops being pulled out continuously or when the vehicle encounters an emergency, the ratchet mechanism will lock, automatically preventing the webbing from being pulled out further.
Regarding the issue of seat belt height, I always pay attention to adjusting the position of the shoulder strap while driving. It's best to position it right in the center of the shoulder—not too high to avoid choking the neck, nor too low to prevent slipping and losing protective effectiveness. Once on the highway, I had to brake hard, and fortunately, the belt was properly positioned on my shoulder, preventing me from hitting the steering wheel. Even with the car shaking, my shoulders remained stable. Usually, there's an adjustable button or buckle for the seat belt in the car. When sitting down, just pull the belt across your chest, making sure it crosses over the collarbone. I remember some newer car models even have height adjustment for the rear seats, which is especially convenient for family members. The seat belt mainly protects the chest and hips; if the height is off, internal organs are more vulnerable during a collision. So, the first thing I do when getting in the car is to adjust the belt position.
As a parent, I pay great attention to the height when fastening the seat belt for my child. When a child sits in a car seat, the shoulder strap must be positioned at the middle-upper part of the shoulder—not too low to prevent slipping, nor too high to avoid discomfort near the neck. I frequently check the adjustable straps of the seat, making slight adjustments based on the child's height, and use a booster seat to ensure the belt lies flat against the body. For adults, the safest position is when the shoulder belt crosses the middle of the shoulder, providing optimal protection in the event of a collision. Incorrect seat belt positioning can also affect airbag coordination. For example, when I switched to a new car model last year, I made sure to adjust the height properly during the test drive for peace of mind.
I'm used to adjusting the seatbelt to the middle of my shoulder to avoid neck injuries in a collision. The principle is that the shoulder strap fixes the body's inertia, and the correct position can cushion the impact, protecting the sternum. Vehicle designs include height adjustment features; just pull the strap to fit when getting in the car. Incorrect positioning reduces protection.
