摘要
不同类型座椅面套拉伸性能差异较大,会影响驾乘人员感知的座椅柔软程度。分析了市场上织物、真皮和人造革等面套拉伸性能的分布,并在此基础上,从拉伸性能角度进行了3组面套柔软性分析:(1)5种市场座椅面套;(2)打孔和未打孔面套;(3)绗缝与未绗缝面套。结果表明:多数面套的纬向断裂强度范围350~715 N,断裂伸长率范围22%~198%。(1)具有较好柔软性又满足断裂强度的面套,在伸长率5%条件下拉伸强度16.9 N,20%伸长率条件下拉伸强度58.9 N;(2)打孔面套柔软性得到改善,密集孔洞适合用在座椅非主要承载区;(3)平面绗缝面套特别是密集绗缝会降低柔软性,不适合用在座椅非主要承重区。研究结果为座椅主要和非主要承重区面套材质选择和造型装饰设计提供了参考。
There are great variations among tensile properties of automobile seat covers,which can affect the feeling of seat surface softness.This paper analysed the tensile properties of fabric,polyurethane leather and genuine leather car seat covers in the market,and on this basis,the softness of three groups of car seat covers,namely,(1)five kinds of seat covers in the market,(2)punched and un-punched seat covers and(3)quilted and un-quilted seat covers,was analysed from the point of view of tensile property.The results show that the ranges of these covers’breaking strength and elongation at break are 350-715 N and 22%-198%,respectively.The covers in group(1)had satisfying softness and breaking strengths,and exhibited 16.9 N of tensile strength under the condition of 5%elongation,and 58.9 N of tensile strength under the condition of 20%elongation.In group(2),the softness of punched covers was improved,and these covers with the dense holes are suitable for use in the non-main load area of car seat.In group(3),the 2D quilted covers,especially the ones with dense quilting,had reduced softness and are not suitable for installing in the non-main load area of car seat.These results provide some references for the material selection and decorative design of the main and non-main load area of car seat.
