How many seat belts are there in the back seat of a sedan?

There are 3 seat belts in the back seat of a sedan. When wearing the seat belt, the shoulder strap should cross the chest cavity, and the waist belt should fit snugly against the hip bone. The purpose of this is to ensure that the impact force in the event of an emergency acts on the bones rather than the soft internal organs. After buckling the seat belt, the buckle will make a clicking sound. However, to ensure that the seat belt is properly fastened and not damaged, passengers should still pull on the seat belt to confirm. A seat belt is a vehicle safety device designed to protect vehicle occupants from harmful movements that may occur during a collision or sudden stop. The function of the seat belt is to reduce the possibility of death or serious injury in a traffic collision by minimizing the secondary impact force that poses an internal collision risk. It also ensures that occupants are properly positioned to maximize the effectiveness of airbags (if equipped) and prevents occupants from being ejected from the vehicle or experiencing vehicle rollover during a collision.
Last time my daughter insisted on sitting in the middle of the back seat, and I had to check the manual to realize that most modern sedans now come with three seat belts in the rear. The left and right sides feature standard three-point designs, with shoulder and lap belts securely fastened. The middle one is usually a two-point belt—just a single strap across the waist. Don’t underestimate these three belts—they prevent rear passengers from hitting the front seats during sudden braking. Once, a friend complained that the seat belt was uncomfortable, so I turned off the engine and lectured him: no matter how short the trip, always buckle up. Also, a reminder: the middle seat belt buckle in the back tends to slip into the seat gap, so pull it out regularly to check if it retracts smoothly, especially in older cars where the springs can get stuck.
Last month, I accompanied a friend to the used car market. While he was test-driving and only focusing on the front-row features, I went straight to the back seat and checked it thoroughly. I noticed that ordinary sedans indeed have three seatbelt anchor points in the rear—left, middle, and right. The three-point seatbelts on the left and right sides are easy to use, while the middle one might feel a bit awkward. Pay special attention to cars that frequently carry children, as the rear seatbelt buckle slots can get clogged with snack crumbs, making them hard to fasten. Also, if you plan to install a child seat in the middle of the rear row, remember to check if the two-point seatbelt is long enough to secure the base. Honestly, many people don’t use rear seatbelts at all, but a traffic police officer friend of mine told me that nearly half of the rear-seat fatalities in accidents they handle are caused by not wearing seatbelts.
Last week, I specifically brought a spring scale to help my cousin inspect the car, testing the locking function of the rear seat belts. Mainstream five-seater cars come standard with seat belt devices for all three rear positions, but the middle one often has lower locking sensitivity. Here’s a tip: if you pull the seat belt faster than 25 km/h, it will automatically lock. If it slips, it means the retractor is worn out. Another detail is the rear seat belt height adjuster—some cars allow the shoulder strap buckle to be moved up or down, ensuring people of different sizes aren’t easily choked. By the way, if you notice the seat belt retracting slowly during the hottest summer days, don’t rush to replace it—it might just be the rubber parts getting sticky from the heat. Turn on the AC for a while, and it should work fine again.
