A method for the manufacture, by the moulding of plastics material, of a motor-vehicle steering wheel which looks like a steering wheel covered with natural leather
摘要：
A motor-vehicle steering wheel is produced by the moulding of plastics material in two steps. In a first step, a polyurethane foam body (6) is moulded around a metal core (5), the body corresponding in shape to the final shape desired but being thinner than the final thickness desired. In a second step, a covering (12) of plastics material is moulded on the polyurethane foam body (6) so as to bring the part to the final thickness desired. The foam used in the first step is produced without the use of chlorofluorocarbons as expanding agents.
摘要（中）：

一种机动车辆方向盘由塑料材料制成的在两个步骤中模制生产的。 在第一步骤中，聚氨酯泡沫体（6）绕金属核成型（5），所述主体在形状上所需的最终形状CORRESPONDING但比要求的最终厚度薄。 在第二步骤中，塑料材料制成的覆盖物（12）被模制在聚氨酯泡沫体（6），以便使该部分到所需的最终厚度。 在第一步骤中所使用的泡沫在不使用含氯氟烃作为发泡剂的生产。
