Design And Research Of Car Siamese Vest Based On Child Safety In The Car

The number of private cars is rapidly growing along with social progress and improving of people's living standards. However, the traffic safety problems are also increasingly. It threats to people's lives seriously especially to the children who are vulnerable groups, therefore increasing the safety of children is drown more and more attention. In recent years, functional clothing design has become the focus of social concern. It is product of the combination among the garment industry and aerospace, electronic, medical. Now it has made significant gains. Functional clothing design will be a safety and effective way to solve the traffic safety problem of children.The subject improves a new device to protect children in the car that combine clothing knowledge with automotive expertise from the point of functional clothing. the children's car Siamese vest was designed from child vest and car seat according to safety, comfort, functionality, aesthetics and other design elements .Children vest, Leg fixed band, adjustable of circumference, and shoulder were designed according to shape characteristics of children and children's ( ) clothing design requirements. It includes the picture of style and structure and the choice of fabric. Car seat and seat belt straps sewn were designed according to child psychological and physiological characteristics including fabric selection, style design and functional structure. Then children's car Siamese vest overall aesthetics was designed from shape, color combinations, patterns selection. It not only meets children's clothing requirements from the view of beauty, comfort and safety, but also has economic and functional. Therefore it effectively protects the lives of children, get s better application.It also needs to design the chart of process analysis and the chart of technology flow. Sewing techniques was determined should from the sewing order, sewing methods, trace requirements, seam type requirements, forms and ironing and other aspects of technical standards. At last the final production was finished. At last it made analysis of simulation experiments use the multi-body dynamics simulation software MADYMO6.2.1 to make simulate the collision of car with child dummy dressed in it and Simulate frontal impact and side impact. Then child dummy's simulation injury parameters are obtained and compared with the regulation values, and have the conclusion finally that the design play an important protective role to protect children in the can when it happens automotive collision.The design fully draws on other strong point of car child safety device. It is easy to install, use a wide range, safety, comfort, and environment protection and so on. It is not only has a certain academic value for the safety of children in the car, but also meets with policy development of the auto industry and textile industry. Further it can expand the application areas of clothing, enhance the application of clothing f knowledge and upgrade application value of clothing subject and promote the clothing industry.
