Description

Technical Field

[0001] This utility model relates to the field of automotive seat headrest technology, and in particular to an automotive seat headrest structure that is easy to manually adjust. Background Technology

[0002] Car seats are core interior components of automobiles, installed in the driver's cabin and passenger compartment, providing support and seating space for drivers and passengers. They are based on a core structure of seat cushion, backrest, and headrest, and are equipped with adjustment mechanisms to achieve multi-directional adjustments such as fore-aft, height, and backrest angle, adapting to the needs of people of different body types.

[0003] Car seat headrests are a core component of car seats, installed at the top of the seat back. Their design conforms to the curves of the neck and head, providing support for the head of passengers. Their function is twofold: firstly, to alleviate neck fatigue during long journeys and improve comfort; and secondly, to act as a crucial safety device, limiting excessive backward head movement in collisions such as rear-end collisions to prevent whiplash injuries to the neck. Together with the seat and seatbelt, they form complete protection. Materials typically include foam-covered fabric or leather, and some models offer height and fore-aft angle adjustments to suit the needs of people of different heights.

[0004] Most existing manual headrests are single-dimensionally adjustable, which is cumbersome and the adjustment range is too large, making it difficult to accurately adapt to the cervical spine curve of drivers and passengers of different heights, and causing fatigue with long-term use.

[0005] Therefore, it is necessary to provide a car seat headrest structure that is easy to manually adjust to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a car seat headrest structure that is easy to manually adjust, solving the problem that existing manual headrests are mostly single-dimensional and have large gaps between the adjustment positions, making it difficult to accurately adapt to the neck fatigue of drivers and passengers of different heights after long-term use.
