Self-adapting car seat

Abstract

The invention relates to a self-adapting car seat. The self-adapting car seat is characterized in that airbags are arranged below skins of a seat cushion, a backrest and a side wing; airbag outer pressure sensors are located between the airbags and the surface skins of the seat; airbag inner pressure sensors are mounted inside the airbags; and each airbag is provided with two electromagnetic valves, wherein one of the electromagnetic valves communicates with atmosphere and serves as an air outlet valve of the airbag and the air pressure in the airbag is reduced when the electromagnetic valve is opened, the other electromagnetic valve is connected with an air cylinder and services as an air inlet valve of the airbag and the air pressure in the airbag is increased when the other electromagnetic valve is opened. According to the self-adapting car seat, the pressure states of various positions such as the seat cushion, the backrest and the side wing of the seat can be detected in real time, and complete fit of the seat and a human body is guaranteed by adjusting the pressure values of the airbags on the seat, so that the pressure of the human body to the seat is distributed uniformly.

Description

technical field [0001] The invention relates to an adaptive car seat, which belongs to a car seat system. Background technique [0002] With the rapid development of automobile automation, the adjustment dimensions of car seats continue to increase, such as seat front and rear adjustment, leg adjustment, back adjustment, lumbar support adjustment, etc. These series of measures improve driving and riding comfort, but People still feel tired when driving or riding in a car for a long time. The fundamental reason is that the surface of the seat cannot fully fit the human body. [0003] The car seat is designed based on the aesthetic appearance and the normal sitting posture of some human bodies. Usually, when the car seat leaves the factory, the seat manufacturer will do a pressure distribution test to ensure the 5th percentile, 50th percentile, and 95th percentile standards The pressure distribution of the human body on the seat cushion and the backrest is even, but for each ...

[0002] With the rapid development of automobile automation, the adjustment dimensions of car seats continue to increase, such as seat front and rear adjustment, leg adjustment, back adjustment, lumbar support adjustment, etc. These series of measures improve driving and riding comfort, but People still feel tired when driving or riding in a car for a long time. The root cause is that the surface of the seat cannot fully fit the human body.

[0003] The car seat is designed based on the aesthetic appearance and the normal sitting posture of some human bodies. Usually, when the car seat leaves the factory, the seat manufacturer will do a pressure distribution test to ensure the 5th percentile, 50th percentile, and 95th percentile standards The pressure distribution of the human body on the seat cushion and the backrest is even, but for each individual, the body proportion, fat and thin degree are not the same, so the seat cannot provide reasonable support for various parts of different human bodies, driving or riding for a long time This discomfort will be evident when
