Abstract
Abstract The body of a sun visor is reinforced with a generally rectangular wire frame. At one corner of the frame is an injection-molded plastic mounting housing molded on the reinforcing frame and that housing receives the mounting shaft for supporting the visor in a vehicle. The wire frame has separated ends which extend past each other and this region of the frame is disposed in an injection molding cavity in which the mounting housing is to be molded. A U-shaped spring is also placed in the injection molding cavity and its side arms extend past the wire frame. A peg in the mounting housing extending through the spring defines the opening in the molded housing past the spring in which the mounting shaft for the visor is received. With the region of the frame and the spring in place in the injection mold for the mounting housing, moldable plastic is injected into the cavity of the mold and the mounting housing is directly molded to the reinforcing frame and the spring.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
A method of fabricating a sun visor reinforcing frame and mounting housing combination, the method comprising: forming an elongate length of reinforcing material of thin width into a reinforcing frame; disposing a region of the frame in an injection molding cavity, wherein the frame is that region is free of contact with the walls defining the mold cavity; disposing a U-shaped spring in the cavity with the arms of the U of the spring straddling around at least part of the region of the frame in the cavity; injecting a moldable plastic into the mold cavity for injection molding a mounting housing around the region of the frame and the spring in the cavity for defining an injection molded mounting housing.
Claim 2
Independent Claim
121 words
A method of fabricating a sun visor reinforcing frame and mounting housing combination, the method comprising: forming an elongate length of reinforcing material of thin width into a reinforcing frame; disposing a region of the frame in an injection molding cavity, wherein the frame is that region is free of contact with the walls defining the mold cavity; disposing a U-shaped spring in the cavity with the arms of the U of the spring straddling around at least part of the region of the frame in the cavity; injecting a moldable plastic into the mold cavity for injection molding a mounting housing around the region of the frame and the spring in the cavity for defining an injection molded mounting housing.
Claim 3
Dependent Claim
55 words
The method of claim 1, further comprising, before the injecting of plastic into the mold, disposing a peg in the mold between the sides of the U-shaped spring toward the web of the spring for centering the spring in the mold cavity and for defining a hole through the mounting housing when it is molded.
Claim 4
Dependent Claim
14 words
The method of claim 2, further comprising removing the peg after the injection molding.
Claim 5
Dependent Claim
15 words
The method of claim 1, wherein the frame is formed into an approximately rectangular shape.
Claim 6
Dependent Claim
46 words
The method of claim 1, wherein the frame has separated end regions and is formed to a frame with end regions which extend past each other and it is those regions of the frame which extend past each other that are disposed in the mold cavity.
Claim 7
Dependent Claim
105 words
The method of claim 1, further comprising bending the sides of the spring down from the web of the U-shaped spring, so that end regions of the arms of the spring are out of contact with the walls of the mold cavity, while upper regions of the arms of the spring nearer the web are generally against the walls of the mold cavity, whereby the end regions of the arms of the spring are fully embedded in the plastic of the mounting housing while the outsides of the upper regions of the of the spring are not covered in the plastic of the mounting housing.
Claim 8
Dependent Claim
16 words
The method of claim 1, wherein the frame is in the form of a metal wire.
Claim 9
Dependent Claim
38 words
A method for fabricating a sun visor, comprising: fabricating a reinforcing frame and mounting housing combination according to the method of claim 1 and thereafter forming a sun visor body over the frame and over the mounting housing.
