    • A method for forming a headliner assembly (10) includes forming a main body (12) having a periphery, and a shape corresponding to a desired shape of the headliner assembly (10); positioning the main body (12) in a mold (58) having a recess (68, 70, 72); closing the mold (58); and injecting foam into the recess (68, 70, 72) to simultaneously form an energy absorbing member (13, 14, 15) and join the energy absorbing member (13, 14, 15) to the main body (12) proximate the periphery of the main body (12). Apparatus (28) for carrying out the method includes a mold (58) having a recess (68, 70, 72) and injection means (74) for injecting foam into the recess (68, 70, 72). A headliner assembly (10) produced by the method includes a main body (12) having energy absorbing members (13, 14, 15) produced by injection molding foam onto the main body (12).
    • 一种用于形成顶篷组件(10)的方法包括:形成具有周边的主体(12)和与顶篷组件(10)的期望形状对应的形状; 将主体(12)定位在具有凹部(68,70,72)的模具(58)中; 关闭模具(58); 以及将泡沫注入到所述凹部(68,70,72)中以同时形成能量吸收构件(13,14,15),并且将所述能量吸收构件(13,14,15)连接到邻近所述外围的主体(12) 的主体(12)。 用于执行该方法的装置(28)包括具有凹部(68,70,72)的模具(58)和用于将泡沫注入到凹部(68,70,72)中的注射装置。 通过该方法制造的顶篷组件(10)包括:主体(12),其具有通过将泡沫注射到主体(12)上而产生的能量吸收构件(13,14,15)。
