Application And Research Of Family Car Seats Comfort

Along with the continuous improvement of people's living standard,automobile gradually became main tool for riding instead of walk in nowadays.When People choose to buy a car,they have not only considered the appearance,fuel consumption,and safety,comfort has gradually become an important measurement indicator for their car selection.Automobile seat is directly related to comfort performance,their support for human body directly affects the static comfort;their vibration absorption performance and resonance frequency are closely related to dynamic comfort;the body posture which affected by seat profile and foam hardness is the basis of operating comfort design,seat-self related operation function design also need to consider the comfort requirements.Thus,seat comfort is one of the most important parts of the vehicle comfort.seat comfort research has become the domestic and foreign automobile enterprises and professional car seat manufacturers concern.In this thesis,combined with the status quo of comfort in actual work,makes a deep analysis on static comfort and operating comfort,and proposed optimization solution for comfort improvement.This paper includes the following main research contents:Firstly,do Comprehensive Analysis for all factors which affects automobile seat static comfort,find out the key factor,then establish the key factor curve model based on the test data,proposed comfort benchmark design.Secondly,do H point tolerance achievement control analysis for some OEM's higher requirement.At last,define seat comfort area based on Chinese human body dimensions,and analysis the physical case in work--“seat remote operating structure comfort improvement”.Based on the research results,apply the comfort benchmark design rules into the physical seat program development to improve the effectiveness of comfort development;Provide strong data analysis support between current situation of China foam manufacturing process and H point tolerance achievement;Use the seat comfort area definition which is suitable for Chinese human dimensions to guide and check seat operating structure layout design in physical program development;Summarize the key point of seat remote operating structure comfort design.
