3、旋转一个角度，当测量气体发生器中心线和座椅SGRP距离时，模块储气罐开口中心线的目标点可以击中上面确定的区域。2．IPSHELFANGLE-STORAGEOFOBJECTS仪表板支架角度——物体的存储Instrumentpanelsurfacerearwardoftheairbagmoduleandintheairbagdeploymentzoneshallslopedownwardwithaminimumangleof10degreesbelowhorizontal.仪表板表面气囊模块后面和气囊展开区域应该向水平面以下倾斜最小10°。Thisalso

5、ployment.四周的仪表板环境不应有助于物体的摆放，这些物体可能阻止展开盖开启或者被充气袋或者气囊上面的充气装置推动。Whenthisrequirementappliestotheairbagdeploymentdoor,onlytheactiveportionofthedelpoymentdoorneedstobeconsideredintheanglemeasurement(i.e.theportionofthedoorthatmovesopenduringdeploymentandthereforehasthepotentialofthrow

6、ingobjects).当这项要求应用于气囊展开盖时，只有展开盖起作用的部分需要在测量角度中考虑（换言之，移动的展开盖在展开过程中会开启，因此可能会扔出物体）。3．PACKAGELOCATION-CANISTERTODOOR布置位置——储气罐相对展开盖Thedistancebetweenthemouthoftheairbagmodulereactioncanassemblyandtheoutersurfaceofthedeploymentdoormayrangefromaminimumof10mmupto45mmmaximum(therangeisto

8、这项要求的目的是促进早期的展开口开启，这样可以减少展开口开启压力和展开口碰撞压力。4.PACK
