    • It is an object of the present invention to provide an improved technique of joining a first body part and a second body part of a sun visor body to manufacture a sun visor for vehicles. The representative A sun visor for vehicles comprises a sun visor body, a first and a second body parts to from the sun visor body, a first weld region, a second weld region. The first weld region includes a first weld formed on the first body part and a first weld formed on the second body part. The second weld region includes a second weld formed on the first body part and a second weld formed on the second body part. The first welds formed respectively on the first and second body parts contact each other and are joined together by vibration before the second welds formed respectively on the first and second body parts contact each other. After that, the second welds contact each other and are welded together by vibration as the first welds are welded together by vibration and at this time, the first welds receive a welding pressure that acts between the first and second body parts, thereby controlling a welding pressure that acts upon the second welds during vibration welding.
    • 本发明的目的是提供一种连接遮阳板的第一主体部分和第二主体部分以制造车辆遮阳板的改进技术。 代表性的用于车辆的遮阳板包括遮阳板体,来自遮阳板体的第一和第二主体部分,第一焊接区域,第二焊接区域。 第一焊接区域包括形成在第一主体部分上的第一焊缝和形成在第二主体部分上的第一焊接部。 第二焊接区域包括形成在第一主体部分上的第二焊缝和形成在第二主体部分上的第二焊接部。 分别在第一和第二主体部分上形成的第一焊缝彼此接触并且在分别形成在第一和第二主体部件上的第二焊接部彼此接触之前通过振动接合在一起。 之后,第二焊缝彼此接触并通过振动焊接在一起,因为第一焊缝通过振动焊接在一起,此时第一焊缝接受作用在第一和第二主体部分之间的焊接压力,从而控制焊接 在振动焊接期间作用于第二焊缝的压力。
