Abstract: Research of the correlation of the biomechanical characteristic of a sitting human and car seat is based on measurements of several basic parameters, such as value of the area contact pressure, map of contact temperature, contact humidity, etc. So obtained map of surface each parameter which we can compare at a same time and so we can identify correlations between these parameters and biomechanical properties of human, e.g. human anatomy, the body forms, age, sex physique etc. Based on these analyzes is possible to optimize the levels of this parameters for obtaining the ideal seating comfort. The correlation between fatigue for the driver and sitting comfort is described in many publications dealing with this theme. However, a repeatability real experiment in a car is questionable [1]. It is therefore preferable to perform these measurements in the laboratory and simulate the same conditions as in moving car at a constant ambient temperature and humidity, with the same test persons. The most suitable is the use in the measurement of different types of car seats and various human.

Abstract: Characteristics cushions from PU foam together with coat determine comfort automobile seats. Frame of car seat with cushion from PU foam and cover serve like body rest. Also perform safety rules, that are demanded on car seat. Cushion in car seat is basically manufactured from PU foam. Experimental testing their property investigate correlation between their characteristic and comfort. One type of experiment is combination static and dynamic loading in medium term time interval . Subject research and content hereof article is recognition transmission characteristics and contact pressures cushions from PU foams in time interval two o'clock in turns static and dynamically weight constant loading.

Abstract: Seats are one of the most important components of vehicles and they are the place where professional driver spend most of their time. Since the beginning of the automotive industry, providing a comfortable, economical and safe ride to the customer, has been the prime objective of all the manufacturers regardless the brand. Present review is done in order to mainly focus on various parameters which lead to seating discomfort in cars. Human experienced seating discomfort has been discussed briefly and ergonomic approach to overcome discomfort has also been analyzed.

Abstract: Drivers posture is one of the critical factors that should be investigated closely and thoroughly in the design and development of car drivers seat. A car driver controls the vehicle movements; therefore, his/her safety and comfort is important to avoid any road injury or unfortunate accident. The two main objectives of this study are to develop2D software for capturingimages of drivers postural angles and to collect comfortable drivers postural angles from the participants involved in the study, while they are driving the cars. To achieve this, an experiment was conducted by using this software for collectingcar drivers postural angles. Forty five Malaysian citizens took part in the data collection process. From the study, a 2D image capture method software for capturing driver postural angles were developed. Finally, a range of comfortable postural angles for Malaysian car drivers were proposed based on the participants perception with respect to safety and comfort.

Abstract: The purpose of this paper is to observe the ergonomic advantages of different car seats and how the driver is constrained to them during the drive. The study was conducted by taking in to consideration the dynamical characteristics of a standard vehicle and subjecting the human body model provided by the AnyBody Modelling System, to inertia and centrifugal forces, in three different driving posture cases. The model proved to be viable and offered an image of different car seats advantages from ergonomic point of view.

Abstract: The safety detection is one of the key procedures in production of car seats and it is also the quality guarantee of car seats. Safety detection items of QBC car seats include the supplemental inflatable restraint system resistance, passenger presence and safety belt power detection. The detection device adopts the passenger presence detection sensor, digital source meter, data acquisition card detect and collection information. The industrial control computer is applied to process information, judge the results. Finally the detection results are saved into the production database in the enterprise server by internet. The application shows that the detection device has high reliability, high automation level and secured data storage mode.

Abstract: According to the requirement of car seat performances, an automatic inspection system of car seat performances based on virtual instruments is developed and put into real production. The paper introduces the hardware configuration, module functions, implementation and application of the system. The system has high accuracy, reliability and stability with multi functions.

Abstract: An automatic detection device was developed to measure the frictional resistance force between the tracks on the brackets of car seats. The device adopted the force sensor to measure the action force of the tracks on line. The industrial computer was responsible for processing the data, dynamically drawing the value curve of the meter, collecting the order from the SCM and sending the controlling signal to the SCM. The applications show that the measuring system has the good dynamic performance, high measuring accuracy and reliability.

Abstract: According to the characteristics of car seat structure and the distribution of car seat load, the finite element static strength model of the car seat is constructed in this paper. The model contains shell elements and beam elements. Some seat structure elements such as welding connection, screw connection, pin connection are simplified in the model. Simulation analysis of the static characteristics of car seat backrest frame model is carried out. At the same time, the experimental research on the static strength characteristics of the back seat is made by the measurements of non-electric physical quantities. By comparing and analyzing the results of experiment and computer simulation of seat static strength, the practicability and credibility of the seat static finite element analysis model and simplified model constructed in this paper are verified. It also proves that the simulation of various connecting forms of the seat structure is effective and is a reliable method in the structural design of the car seat. The model and simulation of the car seat can reduce the cost and shorten the design period.

Abstract: Nowadays advanced high strength steel sheets and related forming technologies play an important role in lightweight construction in the transportation sector. Since especially car seat components are subject to very strict safety demands, the application of these modern steel grades, which provide enhanced strength levels, seems to be a promising strategy to meet the challenge of reducing the sheet metal thickness while maintaining the crash energy absorption capacity. Concerning the high required level of part complexity and accuracy both the reduced formability and the increased springback tendency of advanced high strength steels are challenges for forming technologies compared to conventional steel grades. Against this background the forming potentials of advanced high strength steels are investigated and are made accessible for an application in structural car seat components. The analysis is to be done both experimentally and numerically, focusing on the finite element method (FEM) regarding a reliable process design.
