  • Patent number: 4815194
    Abstract: A method of manufacturing a rectangular frame for a vehicle sunroof in which first and second straight metal profiles (38, 40) are assembled to form a frame stock assembly which is bent at intervals along its length to form the frame. The profiles are arranged as radially outer and inner components, respectively, in the plane of the bend and are coupled by means of a web (42) of the inner component (40) engaging in a slot (44) in the outer component (38). The profiles are assembled together by sliding the web longitudinally along the slot, and interengaging surfaces (43, 45) remain free to slide against one another during bending of the assembly. The profiles are assembled prior to shaping the frame. During bending the profiles can slide relative to one another reducing deformation occurring at the bend and allowing the frames to be formed with tighter bends at the corners than has previously been possible.

  • Patent number: 4585269
    Abstract: A frame for a vehicle sun roof intended for a vehicle having a hard head liner comprises an outer upper frame section adapted to fit into an aperture in a vehicle roof and to engage said roof around the edge of said aperture, an inner frame section adapted to be located below the vehicle roof and to be secured to the outer frame section and a support member adapted to be fitted to the inner frame section and to engage the underside of the vehicle roof around the edge of the aperture. The support member is made of resilient material and is provided with a lip which is adapted to engage a hard head liner of the vehicle roof around the edge of an aperture formed therein to accommodate the frame in order to conceal the aperture in the head liner from view and to provide a support for the head liner.
