pääntuki

Pääntuki, a Finnish term, translates to "headrest" in English. It refers to a component of a seat designed to support the occupant's head. Headrests are commonly found in vehicles, such as cars, buses, and trains, as well as in furniture like chairs and sofas. Their primary function is to enhance comfort by providing a place to rest the head, which can reduce strain on the neck and shoulders during prolonged sitting.

In automotive applications, headrests also play a crucial safety role. They are designed to help prevent or reduce the severity of whiplash injuries in the event of a rear-end collision. By limiting the backward motion of the head, headrests absorb some of the impact force. Modern vehicle headrests are often adjustable, allowing users to position them for optimal comfort and safety. Some are also integrated into the seat design, while others are separate attachments. The design and effectiveness of headrests are subject to various safety regulations and testing standards in different countries. The termääntuki, therefore, encompasses both comfort and safety features depending on its context of use.
