摘要： An automotive seat assembly is provided with an integrated side impact airbag. The seat assembly comprises a seat cushion and a seat back mounted to the seat cushion. A seat cushion trim cover material covers the seat cushion and a seat back trim a cover material covers the seat back. The seat assembly is characterized by a tear seam integrally formed within a bolster section of the seat back trim cover material. The tear seam defines a frangible line of weakness within the trim cover material wherein the airbag will tear through the tear seam when the airbag is deployed and inflated to a position outside of the seat assembly. The subject invention also includes a manufacturing apparatus for forming the tear seam in the trim cover material. The apparatus comprises a template (48) supporting the trim cover material (28). A C-shaped raised ridge (50) extends upwardly from the template to abut the inside surface of the trim cover material (28). A welder (52) is disposed adjacent the outside surface of the trim cover material (28) such that the trim cover material is wedged between the template (48) and the welder (52). The welder is aligned with the raised ridge to form the tear seam within the trim cover material.
摘要翻译：汽车座椅组件设有集成的侧面碰撞气囊。座椅组件包括安装在座垫上的座垫和座椅靠背。座垫装饰罩材料覆盖座垫，座椅靠背装饰覆盖座椅靠背。座椅组件的特征在于一体地形成在座椅靠背装饰罩材料的摇枕部分内的撕裂缝。撕裂接缝限定了装饰罩材料内的脆弱的线条，其中当气囊展开并充气到座椅组件外侧的位置时，气囊将撕裂穿过撕裂接缝。本发明还包括一种用于在装饰罩材料中形成撕裂缝的制造装置。该装置包括支撑装饰罩材料（28）的模板（48）。 C形凸脊（50）从模板向上延伸以邻接装饰材料（28）的内表面。焊接器（52）邻近装饰罩材料（28）的外表面设置，使得装饰罩材料楔入模板（48）和焊工（52）之间。焊机与凸脊对齐，以在装饰罩材料内形成撕裂缝。
