- Sunshades are generally known in the art for blocking or filtering light passing through an opening in a roof of a vehicle.
- the sunshade is generally disposed within a pair of guides and is movable between an open position where the opening is exposed and light is allowed to pass through, and a closed position in which the sunshade covers the opening for blocking or filtering the light coming through.
- Controlling frictional forces between the sunshade and the guides is needed to maintain consistent and smooth movement of the sunshade between the open and closed positions. In other words, when the frictional forces are inconsistent, an applied force required to move the sunshade between the open and closed positions is also inconsistent. It is desired that the applied force be relatively consistent for a user.
- the sunshade It is desirable for the sunshade to operate smoothly when moving between the open position and the closed position. It is also desirable to provide a process for making sunshades that allows quick and easy adjustment of the frictional force acting between the sunshade and the guides to maintain a consistent frictional force and required applied force during the manufacturing process.

Abstract
A sunshade for a vehicle having a first guide and a second guide spaced from the first guide. The sunshade has a pair of edges and includes a substrate layer and an aesthetic layer fixed to the substrate layer to present a show surface. Slide portions are disposed along each of the edges and are adapted to move within the first and second guides as the sunshade moves between an open position and a closed position. The slide portions define a generally corrugated configuration to provide a force that must be overcome to move the sunshade between the open position and the closed position.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 61/084,835, filed on Jul. 30, 2008, which is hereby incorporated by reference in its entirety.
- The subject invention generally relates to a sunshade for a vehicle. More specifically, the subject invention relates to a slide portion for the sunshade that allows movement of the sunshade between open and closed positions.
- Sunshades are generally known in the art for blocking or filtering light passing through an opening in a roof of a vehicle. The sunshade is generally disposed within a pair of guides and is movable between an open position where the opening is exposed and light is allowed to pass through, and a closed position in which the sunshade covers the opening for blocking or filtering the light coming through. Controlling frictional forces between the sunshade and the guides is needed to maintain consistent and smooth movement of the sunshade between the open and closed positions. In other words, when the frictional forces are inconsistent, an applied force required to move the sunshade between the open and closed positions is also inconsistent. It is desired that the applied force be relatively consistent for a user.
- Various methods are taught by the prior art to control the frictional forces including the use of sliding shoes clipped along the edges of the sunshade. Other sunshades employ a curved panel portion to limit contact between the sunshade and the guides, see, e.g., U.S. Pat. No. 6,729,074. Relying on the curve or crown of the panel portion requires that the panel portion have sufficient strength and consistent physical properties that will maintain consistent frictional forces. In other words, variations in the curve or crown or in the physical properties of the sunshade could alter the frictional forces, and consequently, alter the applied force required to move the sunshade between the open and closed positions.
- It is desirable for the sunshade to operate smoothly when moving between the open position and the closed position. It is also desirable to provide a process for making sunshades that allows quick and easy adjustment of the frictional force acting between the sunshade and the guides to maintain a consistent frictional force and required applied force during the manufacturing process. Several variables can contribute to varying the frictional force including the nature of the material (coefficient of friction), the weight, shape, and rigidity of the material, as well as many other factors.
- The invention provides a sunshade for a vehicle. The sunshade is configured to move between open and closed positions within a first guide and a second guide spaced from the first guide. The sunshade includes a panel portion having a pair of edges. The panel portion includes a substrate layer and an aesthetic layer fixed to the substrate layer. At least one slide portion is disposed along each of the edges and is adapted to move within the first and second guides as the sunshade moves between the open position and the closed position. The slide portions define a generally corrugated configuration for providing a force that must be overcome to move the sunshade between the open position and the closed position.
- The invention also provides a tooling assembly for forming the slide portions. The assembly includes a first forming portion having a first fixture. A first insert is movable relative to the first fixture. Additionally, the assembly includes a second forming portion having a second fixture. The second forming portion is adapted to move relative to the first forming portion. A second insert is movable relative to the second fixture and complementarily to the first insert. When the forming portions are moved toward one another, they cooperate to form the slide portion in a corrugated configuration. The first insert and the second insert are adjustable during manufacturing to adjust a height of the corrugated configuration and account for variations of the materials forming the sunshade.
- The invention still further provides a sunshade module for a vehicle. The module comprises the first guide and the second guide. The module includes a sunshade comprising a panel portion having a pair of edges spaced from one another. At least one slide portion is disposed on each of the edges within the first and second guides. Each of the slide portions presents a generally corrugated configuration that provides a force that must be overcome to move the sunshade between the open position and the closed position.
- The slide portions of the subject invention provide several advantages over the prior art designs. By utilizing a generally corrugated configuration, the manufacturer can control forces acting between the sunshade and the guides within which the sunshade moves between the open and closed positions. For instance, by controlling the height of at least part of the corrugations, a larger or smaller normal force results between the slide portions and the guides. As the normal force increases or decreases, so does the frictional force between the slide portions and the guides. Accordingly, the applied force required to move the sunshade between the open and closed positions also changes. As a result, the slide portions can be tuned to achieve a desired applied force. This tuning allows the manufacturer to account for variations in material densities, rigidity, coefficients of friction, shapes, and so on, which may be different for different materials, or even for different lots of the same material.
- Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 7 , a process for manufacturing thesunshade 20 is illustrated. Each of thelayers conveyor 68 having afirst end 70 and asecond end 72. Thelayers oven 74 and are typically heated at a temperature of from about 335 to about 580 degrees F. to achieve a part with a core temperature of approximately 360 degrees F. Of course, this example of processing temperature is not intended to limit the invention. - The stacked layers 34, 36, 42, 44 are removed from the
conveyor 68 at thesecond end 72 and placed in aform station 76, which includes atooling assembly 78 for forming thesunshade 20 and eachslide portion 50 thereupon. Theform station 76 will be described in greater detail below. - The stacked layers 34, 36, 42, 44 are then placed in a trim fixture at a
trim station 64, and held in place to trim the perimeter to a final shape, including cutting out eachslide portion 50 as well as trimming away any flashing disposed about the perimeter. Typically a water jet is used to trim thesunshade 20, however any other appropriate trim system may be employed. A handle opening is also cut through thestacked layers handle insert 80. Thehandle insert 80 is installed into the handle opening on thepanel portion 45 at a handle installstation 82. - The applied force FA required to move the
sunshade 20 in theguides 28, between the open and closed positions is measured at a slideforce test station 92 to ensure that the applied force FA falls within a desired range. In some embodiments the desired applied force FA is 15N to 30N. The manufacturing process described above is merely illustrative and should not in any way be construed as limiting. Other processing steps may be employed in addition to or alternative to those described above. For example, thetooling assembly 78 may be heated in addition to or alternative to heating thestacked layers oven 74 depending on processing requirements of the materials used to form thesunshade 20. - Referring now to
FIGS. 8-11 , thetooling assembly 78 at theform station 76 for forming eachslide portion 50 is described in greater detail. Thetooling assembly 78 includes a first formingportion 98 comprising afirst block 87. A plurality offirst fixtures 84 having a first plurality of fixed formingsurfaces first block 87.

tooling assembly 78 further includes a second formingportion 99 comprising asecond block 91. A plurality ofsecond fixtures 88 having a second plurality of fixed formingsurfaces second block 91. A plurality ofsecond inserts 90, each having a second adjustable formingsurface 89, are operationally coupled to thesecond block 91 and are adapted to move relative to thesecond fixtures 88. The second formingportion 99 is disposed adjacent to the first formingportion 98 and is adapted to complementarily mate with the first formingportion 98 to form thesunshade 20 and eachslide portion 50. Preferably, there are four sets of thefirst fixtures 84 andfirst inserts 86 on the first formingportion 98 that are aligned with and mate with four sets of thesecond fixtures 88 andsecond inserts 90 on the second formingportion 99. - The first inserts 86 and the
second inserts 90 are aligned to mate and cooperatively form thesecond ridge 60 of theslide portion 50. Theinserts second ridge 60. The second height H2 of eachslide portion 50 controls the amount of force between theslide portions 50 and theguides surface 81 and the second adjustable formingsurface 89 are complimentary configured to each other, in a concave-convex relationship, for forming thesecond ridge 60. When thefirst inserts 86 are adjusted to change the second height H2, thesecond inserts 90 are also adjusted substantially the same amount and in the same direction as thefirst inserts 86 so as to maintain a relatively constant distance between the first and second adjustable formingsurfaces panel portion 45, i.e., theslide portions 50 may be further compressed than thepanel portion 45. - In one example, the
sunshade 20 is formed from a first lot of material with theinserts sunshade 20 is within the desired range. When a second lot of material is introduced the applied force FA required to move thesunshade 20 falls outside of the desired range. Theinserts sunshade 20 back within the desired range very quickly or on the fly. Referring toFIG. 11 , theinserts inserts blocks portions inserts inserts inserts - As best shown in
FIG. 12 , theslide force test 92 is performed on thesunshade 20 after it is formed to ensure that the applied force FA required to move thesunshade 20 along theguides sunshade 20 is placed in a pair oftest rails 94 and aforce gauge 96 is attached to thesunshade 20. Thesunshade 20 is pulled through the test rails 94 and theforce gauge 96 measures the amount of force required to move thesunshade 20. The applied force FA is generally measured in Newtons. However, any other appropriate units may also be used without deviating from the subject invention. When the measured applied force FA falls outside of a desired range, the second height H2 of theslide portions 50 can be tuned such that subsequently formedsunshades 20 fall within the desired range. - As shown in
FIG. 13 , in an alternative embodiment aslide portion 150 is a separate structure from thepanel portion 45. A plurality ofclips 161 may be used to couple theslide portion 150 to each of theedges panel portion 45.
