The present invention generally relates to a sun visor for use in an interior of a vehicle, and more particularly relates to a hybrid visor which includes a hybrid clamshell and a body made of a foam material, such as EPP.
2. Description of Related Art
Sun visors are well known and widely used in the prior art. Many different types of visors have been successfully employed in vehicles over the years. Many of these prior art visors have been developed in a variety of ways through which visor bodies and other interior components may be constructed and mounted within the vehicle. Advances in design can often add complexities to the manufacturing processes for interior components. There has been and continues to be a premium in the automotive industry on cost savings, and improvements in the efficiency and speed in the manufacturing processes for such components therein. One area of particular focus in the automobile technology field has been reducing the number and complexity of steps required to assemble interior components, such as visors for use in vehicles. Furthermore, governmental regulations also require less dense or softer interior components to reduce the risk of head injury in vehicle crashes throughout the interior of an automotive vehicle.
Generally, in the prior art, manufacturing complexity continues to drive innovations in the automotive industry, loss of quality and performance in the manufacturing of components for the sake of facilitating production is seldom if ever acceptable. Furthermore, creating simpler versions of existing components within the automotive interior also drives the market. There is a substantial body of art relating to the specific structure of the visor to provide a strong, lightweight construction that matches or compliments the interior trim in a cost effective manner. Of particular interest has been the clamshell type construction, which involves the molding of two shell pieces or clamshell halves, which are joined to form a visor body. In one typical clamshell design, the visor halves are formed as a single piece attached along the longitudinal edge and then folded to form the visor body. The exterior surface can be molded to provide a suitable visor surface or a desired covering can be added in a variety of different ways known in the prior art.
The clamshell design allows the visor body to be constructed relatively quickly and easily, however the various components that are attached to the visor clamshell must in some cases be incorporated with several assembly steps prior to securing the clamshell halves together. For example, some of the known designs require insertion of additional mounting or journaling pieces for retention of the visor pivot rod within the visor body. The construction of the visors having such design is relatively time intensive. Moreover, the various slides, journals, retainers, etc., utilized in the construction may add significant expense and more importantly weight to the overall visor and increase the number of components necessary to build one therein and also may increase the density or hardness of the visor and not meet the governmental regulations regarding head impact standards.
Eliminating parts can reduce the expense of manufacturing and constructing a visor. The decrease in size and weight however can be accompanied by a decrease in strength. The rotatable visors are a concern where flimsy construction of the visor core and slider components may be insufficient to withstand repeated torque actions on the visor shell itself, and in some cases cause dislodging or breaking of the pieces. It is thus desirable in the art to provide a visor that is light weight, easy to manufacturing, using relatively few components and meets all federal regulations requiring head impact standards, yet utilizes a design that is simple and can be easily changed for a variety of interiors of over a wide variety of vehicle lines. Furthermore, it is desirable in the art to develop a visor that provides significant durability to withstand heavy and repeated use and to provide a solid and firm construction with tight tolerances throughout the entire system. Also, it is desirable in the art to provide a visor that is easy to recycle thus creating a visor that is more green and a simpler version of many of the visors now used in the prior art.

Generally, the present invention broadly provides a hybrid visor 20 having a hybrid clamshell 22 with a pivot rod 24 mounted within the clamshell 22 and a foam like body 26 arranged within the clamshell 22 and is captured during assembly with a single step of attaching the hybrid visor shell portions together. The visor 20 as shown in
In the embodiment shown in
The hybrid clamshell 22 may include a pivot rod assembly that comprises a pivot rod 24 and a pivot rod slider 28 arranged on an end thereon. It should be noted that in the embodiment shown a slider 28 is used in conjunction with the pivot rod 24, however it is also contemplated to have embodiments where a pivot rod 24 is arranged within the hybrid shells 32, 34 on its own. The hybrid clamshell 22 may have a channel 46 in which the pivot rod 24 may be arranged and/or other channels 46 molded therein through which the slider 28 may be slidingly arranged within the longer length portion 36 of the hybrid clam shell 22. There may also be molded within the hybrid clamshell 22 a plurality of journals or other channels 48 in which a support arm 50 may be arranged therein. Arcuate retaining surfaces 52 may also be molded therein to allow for rotation of the pivot rod 24 with relation to the hybrid clamshell 22 and for retaining the support arm 50 within the hybrid clamshell 22. It should be noted that any known configuration of channels, arcuate surfaces, or other support surfaces may be molded within the longitudinal portion 36 of the hybrid clamshell 22 to allow for the pivot rod 24 and any associated slider mechanism 28 and slider assembly features to be securely arranged therein. The hybrid clamshell 22 also may include at least one connecting member 40 molded therein for receiving a fastener 54 that will secure the two hybrid shells 32, 34 to one another to form the overall hybrid clamshell 22 as described in the present invention. The first hybrid shell 32 and the second hybrid shell 34 preferably have three connecting members 40 through which fasteners are placed to allow for complete closure of the first shell 32 to the second shell 34 to form the hybrid clamshell 22 for the hybrid visor 20. It should be noted that fastener 54 may be a screw, however any other type of fastener such as a rivet, pin, dowel, or any other known mechanical or chemical fastener may also be used to secure the two hybrid shells 32, 34 to one another to form the hybrid clamshell 22. It should also be noted that in another contemplated embodiment the two hybrid shells 32, 34 may be secured to one another via any known snap fit arrangement and not with traditional fasteners as described above. Such snap fit arrangements may include a predetermined retention cavity 56 having a predetermined shape locking pin or rib 58 inserted therein to create the necessary closing forces and holding forces to secure the first hybrid shell 32 to the second hybrid shell 34 in the present invention. The outer surface of the hybrid clamshell 22 also may have a predetermined shaped surface with a generally curved surface near the outer edges thereof to form the outer visor body as shown in the figures. The hybrid shells 32, 34 also may include the necessary connecting features molded in each shell to receive a D-ring or center pin 30 to allow for the sun visor 20 to be connected and pivoted to and about a mount member on the interior of the vehicle roof.
The hybrid shells 32, 34 also may include as shown in the Figures on the shorter transverse length 38 of the L-shaped hybrid clamshell 22 a molded snap fit system to secure the transverse portion 38 of the hybrid clamshell 22 to one another after assembly of the overall hybrid visor 20. The hybrid shell snap fit system as shown in the Figures generally includes an elongate locking channel 56 that includes a plurality of orifices through the surfaces thereof, yet works in conjunction with an elongate rib that mates with the channel 56 with the rib 58 having locking members that are arranged in an complimentary manner to the orifices in the locking channel 56 of the transverse portion of the clamshell 22. The locking members interact with the orifices of the locking channel 56 thus allowing a locking surface of the locking member to engage a locking shoulder of the locking channel 56 thus ensuring that the transverse portion 58 of the hybrid clamshell 22 is secured to one another after having the outer covering or material 60 of the hybrid visor 20 is tucked therein and held therein. It should further be noted that in another contemplated embodiment the transverse portion 38 of the hybrid clamshell 22 may include a plurality of teeth that would help to hold and secure the cover material 60 to the hybrid visor 20 during the final assembly steps. These teeth generally extend in an inward direction from the outer peripheral edge of the hybrid shells 32, 34 transverse portion. The transverse portion 38 or longitudinal position 36 of the clamshell 22 may have any known shape not just those shown in the Figures. It should further be noted that the longitudinal portion 36 of the hybrid clamshell 22 may also include the necessary electrical connections to allow for electricity to pass through the pivot rod 24 to an optional vanity mirror assembly 62 or other lights in order to allow for lights to illuminate a mirror and the person looking in the vanity mirror or other objects on or near the hybrid visor 20.
In the embodiment shown the slider 28 of the hybrid visor 20 may be secured over an end of the pivot rod 24. The rod 24 is slidably supported within the channel 46 of the hybrid clamshell 22. The slider 28 may have locating projections 64 extending from both sides thereof and in one contemplated embodiment the slider projections 64 generally have a cylindrical shape, but any other known shape may also be used for the locating projections 64. In the embodiment shown two locating projections 64 extend from both sides thereof. The plurality of locating projections 64 assist in providing relative support between the visor 20 and pivot rod 24 via an interaction between the channel 46 and the supporting projections 64 sliding therein. The slider 28 may be attached to the pivot rod 24 that via journals which rotatably retain the pivot rod 24 therein. The slider 28 further may have a plurality of supporting extensions 66 which slidably engage with the support arm 50 wherein the support extension 66 is preferably an arcuate member that is positioned over the support arm 50. The slider 28 may also include an end projection at one end of the slider 28 opposite of the pivot rod 24. The projection may be received in a substantially mating stop position at the opposite end of the channel of the visor 20. Thus, the slider 28 slides back and forth relative to the hybrid clamshell 22, a stop limits the travel of the slider 28. It should further be noted that the visor 20 may also include a cover member 68 arranged over a predetermined portion of the slider 28. The slider 28 also may include a detent mechanism to allow for the visor to be placed in various positions relative to the windshield and interior roof of the automotive vehicle. The support arm 50 may be arranged within journaled surfaces or any other known holding surface molded into the hybrid shells 32, 34 thus being retained therein when the hybrid shells 32, 34 are secured to one another in its final assembly position.
The hybrid clamshell 22 may also include a retaining rib 70 generally located along the inner peripheral edge of the hybrid clamshell 22. The retention rib 70 may extend from both the first hybrid shell 32 and the second hybrid shell 34. Generally, when viewed from the side the retention rib 70 has a generally L-shape. This retention rib 70 may extend a predetermined distance from the inner surface of the hybrid shells 32, 34. The retention rib 70 may be used in conjunction with a retention channel 72 on a visor body 26 to properly align and secure the visor body 26 with respect to the hybrid clamshell 22. The retention rib 70 may have any known shape and cross section.
The hybrid clamshell 22 in the embodiment shown may also include a vanity mirror support member 74. The vanity mirror support member 74 generally extends from a bottom portion of the longitudinal length 36 of one of the hybrid shells. In the embodiment shown the vanity mirror support member 74 generally has a rectangular shape. However, the shape will mimic that of the outer portion of the visor vanity mirror assembly that is to be attached and secured to the hybrid visor 20 according to the present invention. The visor mirror support member 74 may include a plurality of locking and aligning members 76 extending therefrom wherein these members 76 hold and align the vanity mirror assembly in a predetermined position with respect to the hybrid clamshell 22 and visor body 26. These locking and aligning members 76 may be arranged anywhere on the visor mirror support member 74. Orifices 78 may also be arranged through the visor mirror support member 74 to allow for electronics and other connecting members of the vanity mirror assembly to interact therewith to create a secure connection between the visor mirror support member 74 and the vanity mirror assembly. The vanity mirror support member 74 generally may have a retention rib 70 arranged around the outer periphery thereof and extending in the same direction as the retention rib 70 extending around the inner periphery of the hybrid clamshell 22. Generally, in cross section the retention rib 70 may have a generally rectangular or square shape, however any other known shape may also be used for the retention rib 70 of the hybrid clamshell 22.
The hybrid clamshell 22 is generally molded from a hard plastic or thermoplastic material and in one preferred embodiment an ABS material is used. However, any other plastic material or composite material capable of being molded into predetermined shapes, such as that needed for the hybrid clamshell 22 may also be used according to the present invention. It should also be noted that other forming techniques may also be used to create the hybrid clamshell 22 such as but not limited to heat forming, machining, powder systems, etc. Hence, the hybrid shells 32, 34 of the present invention generally may have a plurality of complimentary structures that will secure the first and second shell 32, 34 to one another wherein the structures may include features that use fasteners or snap fit systems to create the securement between the first and second hybrid shell 32, 34. It should also be noted that the pivot rod 24 is capable of rotating with respect to the clamshell 22 and slide in a longitudinal direction with respect to the longitudinal length 36 of the clamshell 22.
The drawings also show a hybrid visor 20 having a visor body 26 made of a foam like material. In one contemplated embodiment the foam like material is an expanded polypropylene (EPP) material. The EPP visor body 26 is capable of being molded into any known shape with any known curve arranged therein. The EPP visor body 26 also is capable of being molded with any known density to allow for the hardness or softness of the EPP visor body 26 to be adjusted depending on the environment in which the hybrid visor 20 will be used. The EPP body 26 generally will be formed and molded into a generally rectangular shape. However, extensions, cutouts and other shapes may be molded into the EPP body 26 and those shown in the Figures are Just one contemplated embodiment any other known shape may be used for the EPP body 26 depending on the environment in which the hybrid visor 20 will be used. The EPP body 26 generally may be molded using EPP beads and the necessary molding equipment to form the visor body 26 into the desired shape, such as but not limited to those shown in the Figures. The EPP visor body 26 generally may include a retention channel 72 arranged along a longitudinal portion thereof and a transverse portion thereof which generally is complimentary to and mirrors the retention rib 70 of the hybrid clamshell 22. The retention channel 72 may have a predetermined depth but generally is the same as the height of the retention rib 70 of the hybrid clamshell 22. The retention channel 72 of the EPP body 26 generally is molded into both sides of the body 26 such that both shells 32, 34 of the hybrid clamshell 22 will be arranged within a retention channel 72 when the hybrid shells 32, 34 are secured around the EPP visor body 26. The EPP visor body 26 also may include a plurality of orifices 80 therethrough in one embodiment contemplated for receiving a visor vanity mirror assembly or other accessories that may be attached to the visor 20. In one embodiment shown in
In one embodiment shown in
In another embodiment shown in
During operation, the hybrid visor 20 can be used on both the passenger and driver side of the automotive vehicle. Each of the visors 20 may have the EPP body 26 and the hybrid clamshell 22 arranged therein, wherein the outer surface of both portions will create a nice smooth surface such that the user of the vehicle will not know that a hybrid visor 20 is being used. The hybrid visor 20 may also include a thin layer of padding or other material between the cover material 60 and the visor body 26 and clamshell 22. The use of the hybrid visor 20 may greatly reduce the weight of the visor while keeping the rigidity and stiffness of the visor 20 that the user of the vehicle has become accustomed to. The hybrid visor 20 with the generally hard plastic hybrid clamshell 22 ensures that the EPP visor body 26 will not bend or flex where it is not designed to. The hybrid visor 20 design generally has a simple basic version and is easily optioned into a sliding visor having a vanity mirror therein depending on the parts molded into the hybrid clamshell 22 and visor body 26. The addition of all of these parts generally only increases the weight a nominal amount and does not affect the durability and stiffness of the hybrid visor 20. Furthermore, the hybrid visor 20 has a visor body 26 that does not need reinforcements, such as metals, or plastic frames therein to create the durability and stiffness as that of the more expensive visors to make as seen in the prior art. Therefore, the hybrid visor 20 can be used for any known visor because the design of the visor body 26 can be changed by a simple molding procedure. Furthermore, the hybrid visor 20 also is easy to recycle at the end life of the automotive vehicle, thus creating a greener interior component for the manufacturers to tout in the ever increasing green vehicle market. To manufacture the hybrid visor 20 of the present invention a manufacturer would mold the hybrid clamshell 22 either as one piece with a hinge along the top peripheral edge thereof or as two separate pieces depending on the manufacturer's environment and needs. The first and second hybrid shell 32, 34 would be molded with the necessary channels and connecting members therein to allow for insertion of any options that may be required in the hybrid visor 20 such as but not limited to a sliding visor, clips, rotational mechanisms, electronics, transmitters, a vanity mirror assembly, and/or a D-ring or center clip. Generally, the preferred material for molding of the clamshell 22 is an ABS or thermoplastic material. The hybrid shell 32, 34 would also have the retention rib 90 molded therein to allow for interaction and securing of the visor body 26 between the hybrid shells 32, 34. The manufacturer also would mold the visor body 26 out of an expanded polypropylene material. It should be noted that any other foam like material may also be used. The mold of the visor body 26 may include any necessary cavities, curves or the like therein to allow for the visor body 26 to fit in the interior of the vehicle in which the hybrid visor 20 will be used. The visor body 26 may include any necessary cavities for any accessories, such as vanity mirror assemblies, lights, clips, transmitters or any other known accessories for use on the hybrid visor 20. After the molding of the EPP body 26 the assembler will position a pivot rod 24 between the molded surfaces of the hybrid shells 32, 34 along with, if it is required as an option, a slider 28 and a support arm 30. Next, the visor body 26 will be positioned along the inner periphery of the hybrid clamshell 22 such that the retention channel 72 along the visor body 26 will have arranged therein the retention rib 70 generally along the inner periphery of the visor clamshell 22. Next the first shell 32 will be secured to the second shell 34 thereby aligning and holding the visor body 26 between the shells 32, 34 along a generally L-shaped path defined by the visor body retention channel 72 and hybrid clamshell retention rib 70. Securing the first shell 32 and second shell 34 in one embodiment contemplated will occur via fasteners opened along the longitudinal portion 36 thereof and via a snap fit system along the transverse portion 38 of the hybrid clamshell 22. Generally, the fasteners will be arranged therein first and then a cover material 60 will be positioned over and secured over the hybrid clamshell 22 and visor body 26 in any known connecting methodology. It should be noted that any type of material 60 may cover the outer portion of the hybrid visor 20 and any methodology may be used for the attachment and securing of that covering material 60 over the outside of the visor 20.
In one contemplated embodiment the cover material 60 will generally be in the form of a sock with an orifice on one end thereof. The orifice will be arranged over the visor body 26, the end of the pivot rod, and the hybrid clamshell 22 and then either folded or tucked within the open end of the transverse outer edge of the hybrid clamshell 22. Then the transverse portion 38 of the hybrid clamshell 22 will be secured into secure engagement with one another thus pinching and holding the sock like cover material 60 in a tight relationship to the outer surfaces of the hybrid clamshell 22 and EPP visor body 26. Next, any exterior accessories will be connected to the visor 20, such as a D-ring 30 or vanity mirror assembly 62. These will be snap fit or engaged in any other known method into engagement with a molded portion of the hybrid clamshell 22. It should be noted another contemplated embodiment will involve a plurality of teeth extending from an inner peripheral edge of the transverse portion of the hybrid clamshell 22 which will further hold and secure the open end of the sock like cover material 60 between the two visor clamshell portions 32, 34. Another contemplated embodiment will have the open end of the sock 60, after the sock 60 is arranged over the visor body 26 and hybrid clamshell 22 closed with a stitch line arranged along the open end and then such stitched end tucked into the gap between the edges of the transverse outer edge of the first and second shell 32, 34 and the first and second shells 32, 34 secured to each other via a snap fit system as described above. Any other technique for tucking and folding the cover material/sock 60 into the transverse outer edge of the hybrid clamshell 22 may also be used to ensure the cover is tight and gives an aesthetically pleasing outer cover surface to the hybrid visor 20.
Therefore, the hybrid visor 20 as described in the present invention provides a simple version of a visor 20 that is capable of being used with any number of options or as a basic visor with no accessories. This visor 20 is easy to manufacturer, is lighter in weight and will reduce the overall cost to the manufacturer of the visors. It also provides a visor 20 that meets or exceeds all head impact requirements through the use of the EPP visor body 26 and the plastic hybrid clamshell 22. The visor 20 also provides for easy recyclability thus allowing a manufacturer to tout of the greenness of such visor 20 in the ever increasing green conscious consumers of modern day vehicle buyers. The visor 20 also is capable of being molded into a variety of shapes to allow for low cost alternatives to manufacturers. Furthermore, it provides a visor 20 that is just as stiff as all plastic visors or just as stiff as visors using EPP with multiple inserts of metal and plastic therein to provide the necessary stiffness and robustness that users of automotive vehicles require in their visors while also providing the necessary head impact requirements.
The present invention has been described in an illustrative manner. It is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than that of limitation.
Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described.
