Abstract: A ball and toggle assembly for a prismatic interior rearview mirror of a vehicle comprises a ball and body member and a toggle member. The ball and body member and the toggle member are separately formed from separate polymeric materials and joined together. The flexural moduli of the separate materials are selected such that the ball and body member is substantially rigid while the toggle member is flexible. The toggle member is preferably molded over the body member and secured thereto via a mechanical interconnection of the toggle member material to the body member material. Preferably, the ball and body member comprises an engineering polymer, such as a glass-filled thermoplastic material, while the toggle member comprises a polyolefin, such as a homopolymer or co-polymer polypropylene material.

Abstract translation: 用于车辆的棱镜内部后视镜的球和肘节组件包括球和主体构件以及肘节构件。 球和本体构件和肘节构件由单独的聚合物材料单独形成并连接在一起。 选择分开的材料的弯曲模量使得球和本体构件在肘节构件是柔性的时基本上是刚性的。 肘节构件优选地模制在主体构件上并且通过肘节构件材料与主体构件材料的机械互连而固定到其上。 优选地，球和本体构件包括工程聚合物，例如玻璃填充的热塑性材料，而肘节构件包括聚烯烃，例如均聚物或共聚聚丙烯材料。
