2-point seat belt? 3-point seat belt? What are those??! Why is it important for me to know?
Some might still not know what are the differences between these type of vehicle safety belt or seat belt. A 2-point belt attaches at its two end-points (as per picture). It is also commonly known as a lap belt, fitted mainly at the lower hip. This type of seat belt is most common in the middle rear passenger seat of older cars.
A 3-point seat belt is in a Y-shaped arrangement, containing a lap belt and a sash belt or diagonal belt together in one piece and is connected at 3 points. In a collision, the 3-point seat belt spreads out the energy of the moving body over the chest, pelvis, and shoulders. With wider area of coverage, risk of injuries can be reduced compared to if the impact force is only concentrated at a smaller portion of the body.
Volvo was the one who introduced the first production of three-point seat belt in 1959. In Malaysia, starting from 2015, all newly approved model of passenger vehicles should be fitted with 3-point seat belts in all its seats including the middle rear passenger seat.
It is important to understand the type of vehicle seat belt in your car as all UNECE approved child restraints will need to use a 3-point seat belt (for belt attachment). Always refer back to your vehicle owner’s manual and child restraint system manual for instructions on installation.
