Description

Technical Field

[0001] The invention relates to a car seat, in particular to an adjustment method for a flat-lying car seat. Background Art

[0002] With the improvement of people's living standards, cars have become an important means of transportation for people to travel. Intelligence, safety, comfort and environmental protection are the future development direction of cars. As an object that comes into direct contact with the human body, the comfort of car seats is particularly important. At the same time, people's demand for the functionality and personalization of car seats is also increasing.

[0003] The angle of traditional car seats can only be adjusted by flipping them backwards, and they cannot be flipped to a horizontal state. At the same time, traditional car seats will take up a lot of rear space when flipping backwards. If a new type of car seat is designed that can use the front space of the seat and reduce the space occupied by the rear side during the flipping process, the functionality of the car seat will be greatly improved. At the same time, if the car seat can be completely flat, passengers can lie on the seat to rest, and the comfort of the car seat will also be greatly improved. Summary of the invention
