Why Are Car Headrests Uncomfortable?
1 Answers
Because the headrests in cars are not designed for comfort but as a safety feature. Here is a detailed introduction to car headrests: 1. Function: In the event of a rear-end collision, the human body tends to jerk backward due to inertia. At this moment, the pressure from acceleration or deceleration is concentrated on the vulnerable neck and head. The headrest serves as a buffer, protecting the head. 2. Classification: They are mainly divided into two categories: non-adjustable and adjustable. Adjustable car headrests are further classified into manually adjustable and automatically adjustable types. The manually adjustable type can only be adjusted in height unidirectionally, while the automatically adjustable type can adjust in two dimensions automatically.
