Seat headrest with self-adaptive adjusting function and control method thereof

Abstract

The invention discloses a seat headrest with a self-adaptive adjusting function and a control method of the seat headrest; the seat headrest comprises an air cushion adjusting assembly, a distance measuring monitoring system, a pressure monitoring system, a pressure adjusting device and a control system, and the air cushion adjusting assembly comprises a plurality of foaming air cushions embeddedin the headrest; the distance measuring monitoring system is used for monitoring the distance between the head of a passenger and a headrest, the pressure monitoring system is used for monitoring thepressure distribution condition on the headrest, and the control system is used for monitoring data feedback of the pressure monitoring system and the distance measurement monitoring system in real time and controlling the pressure adjusting device to inflate or deflate the foaming air cushion. Under the condition that certain rigidity and strength are guaranteed, the light weight of the seat headrest assembly is achieved, intelligent adjustment of the wrapping performance of the headrest height, the headrest inclination angle, the head back gap and the like can be achieved according to passengers with different sitting postures, different head shapes and different body weight heights, the safety of the passengers can be guaranteed to a greater extent, and the requirement of people for riding comfort can be met.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a seat headrest with an adaptive adjustment function and a control method thereof. Background technique [0002] As one of the key parts of the car, car seats require not only reasonable layout and high safety performance, but also people's requirements for lightweight, intelligent, sporty and comfortable car seats are getting higher and higher. These high requirements It has become an important direction for the future development of car seats. [0003] As a representative of lightweight and intelligent development in the future, the integrated seat has attracted more and more attention from automotive design researchers. However, although the existing one-piece seat integrates the seat back and the headrest into a whole, the headrest part is generally supported by a headrest frame made of metal material. Compared with the split-type seat, the one-piece The adjustment flexib...

However, although the existing one-piece seat integrates the seat back and the headrest into a whole, the headrest part is generally supported by a headrest frame made of metal material. Compared with the split-type seat, the one-piece The adjustment flexibility of the headrest part of the seat is poor, and the ride comfort is relatively poor
