Headrests minimize the effects of forces on the cervical spine caused by a sudden change in the vehicle's movement, such as a hard stop or a crash. They are connected to the seat via supports or bars. The Headrest Supports are therefore safety-related parts that must meet the demands for a high degree of function. In addition, since they are a visible part of the vehicle's interior, they must meet the highest expectations visually. By using thin-walled tubes instead of standard tube measurements, the weight of headrest supports can be reduced by up to 30%.

To increase passenger safety even further, the new trend is toward "active headrests". They reduce the distance between the head and headrest caused by the vehicle's own crash sensors or caused mechanically by the inertial forces of the vehicle occupants in the event of a rear-end impact.  By reducing the distance, they counteract overstretching of the cervical spine (whiplash).
