  • Patent number: 7338108
    Abstract: 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.

  • Patent number: 7118156
    Abstract: A sun visor for a vehicle may include a sun visor body (10) and a mirror unit (20) attached to the sun visor body (10). The mirror unit (20) may have a rotatable attachment (35) that can rotate along the attached face of the sun visor body (10). Further, the mirror unit (20) may have a mirror holder (22) with a mirror. The mirror holder (22) is rotatably connected around a rotatable axis to the rotatable attachment (35). The rotatable axis may extend along the rotatable face of the rotatable attachment (35). The mirror holder (22) may be displaceable between a stored position along the sun visor body (10), and a used position protruding from the sun visor body (10) at some angle. The mirror of this sun visor is angle-adjusted in two independent directions. The directions are perpendicular to each other. Therefore, it is easy to set a preferable reflecting angle to the mirror and the construction may be simple.
