    • A cover for an air bag unit having a patterned tear seam therein defined by an integrally bonded, thermoplastic filler strip as the cover material and including a material having properties different than that of the cover material. Apparatus for forming the cover includes a thin shell mold having an inner surface that is heated to melt thermoplastic material cast thereon. A powder box adapted to contain thermoplastic material therein for distribution onto the thin shell mold carries a gasket having a shape corresponding to the tear seam shape. The powder box and gasket are adapted to be connected to the thin shell mold for forming a sealed footprint on the inner surface during distribution of the cast material against heated surface portions of the thin shell mold to form a thermoplastic cover with an opening therein that has the tear seam pattern. The opening is later filled with the lesser strength thermoplastic material to form an integrally bonded thermoplastic filler strip.
    • 一种用于气囊单元的盖,其具有图案化的撕裂缝,其由作为覆盖材料的整体结合的热塑性填料条限定,并且包括具有与覆盖材料不同的性质的材料。 用于形成盖的装置包括具有内表面的薄壳模,其被加热以熔化在其上浇铸的热塑性材料。 适于在其中容纳热塑性材料以分配到薄壳模具上的粉盒载有具有对应于撕裂缝形状的形状的垫圈。 粉盒和垫圈适于连接到薄壳模具,用于在将铸造材料分配到薄壳模具的加热表面部分的同时在内表面上形成密封的足迹,以形成其中具有开口的热塑性盖, 撕裂图案。 开口稍后用较小强度的热塑性材料填充以形成整体结合的热塑性填料条。
