Product Details
A car headrest is a comfort and safety device for drivers.
In a rear-end collision, the human body will be thrown backward due to inertia. At this time, the pressure of vehicle acceleration or deceleration is concentrated on the vulnerable neck and head, while the headrest plays a buffering role to protect the human head.
They are mainly divided into two categories: non-adjustable and adjustable. Adjustable car headrests are further divided into manual and automatic adjustable types. Manual adjustable headrests can only be adjusted in height, while automatic adjustable headrests can be automatically adjusted in two dimensions. Car headrests are one of the items in the national mandatory certification and inspection project for complete vehicles. There are strict regulations on materials, strength, energy absorption, position and size. The national standard only stipulates the configuration of car headrests for the front seats of passenger cars, but there is no mandatory regulation on whether the rear seats should be equipped with car headrests. Foreign countries, such as the EU, also do not have mandatory standards for rear seat headrests.
Even at a speed of only 10 km/h, in the event of a collision, the force of acceleration and deceleration of the vehicle is concentrated on the vulnerable neck. Without the protection of a car headrest, the necks of the occupants are easily injured. According to relevant departments, neck injuries are one of the most common injuries in car accidents. Data show that in 26% of rear-end collisions, the occupants' heads or necks are injured. Under the same conditions, the probability of neck pain is reduced by 40% for occupants who use headrests correctly compared to those who do not, and the probability of neck injury is reduced by 24% for occupants who use high-quality headrests compared to those who use inferior headrests. In a traffic accident, the huge impact force of the collision is concentrated on the vulnerable neck, which may cause injury to the spine of the occupants, and in severe cases, it may even lead to neurological problems, paralysis, or even death. With a car headrest, the huge instantaneous impact force during an accident can be effectively buffered, protecting the vulnerable cervical vertebrae and reducing the chance of neck injury.
