SIDE WINDOW DEFLECTOR

Abstract

A side window deflector has a body, and a flange joined to the body for fitting into a channel of a vehicle door window. At least one camming facet is formed on an inner surface of a deflector body end portion, adjacent a junction of an end portion lower edge and a flange lower edge. An advancing top edge of a window glass will encounter this camming facet before it encounters any other structure of the body end portion. Some embodiments have two camming facets. The camming facet eases the upward travel of the window glass into its channel. The main and end portions of the body have curved and recurved transitions to the flange, mitigating against bending stress.

DETAILED DESCRIPTION

[0034] A representative vehicle 100 is shown in FIG. 1. This vehicle 100 is a late-model pickup truck with an extended cab. Vehicle 100 has a left front door 102 and a left rear door 104, and, of course, corresponding right front and rear doors (not shown). The front door 102 has a front glass pane or window glass 106 that may be raised or lowered. Similarly, the rear door 104 has a rear glass pane or window glass 108 that may be raised or lowered. A front side window deflector 110 has been installed in an upper channel of a front door window frame 112, and a rear side window deflector 114 has been installed in an upper channel of the rear door window frame 116. Corresponding side window deflectors (not shown) are of course installed in the right door windows (also not shown). Vehicle 100 has a longitudinal or fore-and-aft axis 118 which is horizontal and which is used herein as a reference in describing the deflectors 110 and 114.

[0035] As representative vehicle 100 demonstrates, modern vehicle side door glass panes usually are not disposed in vertical planes, but rather are tilted upwardly and inwardly. Further, the glass panes may not be planar or move in planes. Instead, panes 106 and 108 typically are slightly concave relative to a vehicle center C (FIG. 2). The deflectors according to the invention will therefore be described using a frame of reference seen in FIG. 3. An x direction is horizontal and is substantially aligned with vehicle axis 118, although x may be slightly toed in, particularly for front window pane 106, to give the vehicle 100 better aerodynamics. A y direction is transverse or side-to-side, at ninety degrees to vehicle axis 118, and is horizontal. Herein reference is occasionally made to an inboard or outboard direction, both of which are parallel to the y direction. Inboard means towards axis 118, while outboard means away from axis 118. A z direction usually is concavely curved relative to center C, although its radius of curvature may be much larger than the distance of, e.g., pane 106 to center C; in other embodiments, z may be straight. The z direction is meant to emulate the vertical curvature and path of travel of the side window glass 106 or 108. In recent vehicles the z direction is oriented more to the vertical than it is to the horizontal, usually tilts inward as it proceeds upward, and is at a ninety degree angle with respect to direction x.

[0036] Since direction z is often not straight, surface xz may not be planar but instead may be a slightly curved sheet. Some of the structure of the invention therefore will be described and claimed in reference to an xz sheet rather than an xz plane. Any xz sheet will be parallel to direction x and will conform in its curvature to the curvature (if any) of direction z; any xz sheet will be aligned to directions x and z.

[0037] As seen in FIG. 4, the front window deflector 110 is elongate in an x direction (substantially side to side in this FIGURE). The two main components of deflector 110 are a body 400 and a flange 402. The body 400 has a main portion 404 that, except for a recurved segment described below, is concave relative to center C, and curves in a yz plane between an upper margin 406 and a lower edge 408, where any yz plane is aligned to directions y and z. The flange 402 may be planar for ease in manufacture, or may conform to an xz sheet defined by the curvature of the front window glass for a particular make and model; flange 402 may be slightly concavely curved. Because of the shape of deflector body 400, the lower edge 408 throughout main portion 404 will be outboard of the upper margin 406 and flange 402. The flange 402, with respect to main portion 404, extends upwardly and a little inwardly from upper margin 406.

[0038] Deflector 110 has a first, or rear, end portion 410. In both embodiments illustrated herein, the rear end portions are capped in that they curve around from the main portion in an xy plane to the flange. End portion 410 curves around from a margin 412 that it makes with main portion 404, to an inboard margin 414 at which it is joined to flange 402. The overall curvature of end portion 410 transitions from being curved only in a yz plane, to being curved only in an xy plane as the end of the flange 402 is approached. The curved surfaces of main portion 400 are smoothly continuous with corresponding curved surfaces of end portion 410.

[0039] Body 400 has a second, front end or portion 416 that conforms to the typically slanted front margin of the front window frame 112. The front end portion 416 is joined to main portion 404 and extends downwardly and forwardly therefrom. Front end portion 416 has an upper/forward margin 420 to which flange 402 is joined and from which flange 402 forwardly extends. Front end portion has a bottom/rear edge 422 that is located in an outboard direction from flange 402 and margin 420. Like main portion 404, front end portion 416 is concavely curved relative to vehicle center C. In this illustrated embodiment, the front end portion 416 is not capped like rear portion 410. In other embodiments, front end portion 416 could be capped.

[0040] As seen in FIG. 5, a camming facet 424 is formed on an inner surface 426 of end portion 410. The main portion 404 has a center 499 which is used as a reference to describe certain directions of curvature.

[0041] As seen in more detail in FIG. 6, a lower edge 428 of rear end portion 410 forms a junction 500 with a rear lower edge 502 of flange 402. Lower edge 428 is in this embodiment coplanar with main portion lower edge 408. The camming facet 424 is disposed to be adjacent junction 500. In this front-window embodiment, flange edge 502 makes a corner at junction 500 with lower edge 428, and extends away from junction 500 and upwardly relative to direction x. As will be further described below, this makes sure that the camming facet 424 is the first structure of end portion 410 that an advancing top edge of glass 106 will encounter. Flange edge 502 may make an angle of about 15 degrees relative to lower edges 428 and 408.

[0042] The rear window deflector 114 is seen in more detail in FIGS. 7 and 8. Deflector 114 has a body 600 that is elongate in the x direction. A main portion 602 of body 600 has an upper margin 604 and a lower edge 606. Flange 616 is joined to main portion 602 at upper margin 604, is joined to end portion 608 at margin 614, and is joined to end portion 610 at margin 620. Except for a recurved upper segment described below, main portion 602 is concavely curved in a yz plane relative to vehicle center C. Unlike front window deflector body 400, rear window deflector body 600 has two capped ends: a first, rearward end portion 608, and a second, forward end portion 610. At its margin 612 with main portion 602, end portion 610 is curved only in a yz plane, but then smoothly and continuously transitions to being curved only in an xy plane as flange margin 614 is approached. Most, but not all, of this xy curvature will be concave with respect to main portion center 630 (FIG. 8). Similarly, end portion 610 is curved only in a yz plane at margin 618, but then smoothly and continuously transitions to being only curved in an xy plane as margin 620 is approached. Most, but not all, of this xy curvature will be concave with respect to a main portion center 630.

[0043] As seen in FIG. 8, a first camming facet 700 is formed on an inner surface 702 of rear end portion 608. Similarly, a second camming facet 706 is formed on an inner surface 708 of end portion 610.

[0044] FIGS. 9-11 show camming facet 700 in more detail. Camming facets 424 and 706 are correspondingly similar in shape, position and function relative to the capped end portions with which they are associated. In the illustrated embodiment, facet 700 is roughly triangular in shape, with an apex 900 upwardly displaced from end portion lower edge 704. Facet 700 could take other shapes and/or have curved sides. Facet 700 is positioned to be adjacent a junction 904 between flange lower edge 902 and end portion lower edge 704. Facet 700 extends for most of end portion edge 704. Lower edge 902 may make an upward angle from lower edge 606, such as about 15 degrees. As seen in FIG. 10, a thickness 1000 of flange 616 stays fairly constant and is thinner than a thickness 1002 of body main portion 602 and of the nonfaceted region 1006 bounding facet 700 of the end portion 608. A thickness of region 1006 may be about 3 mm, while a thickness of 1000 of flange 616 may be about 1 mm. This relatively thin flange thickness is achievable if a particularly tough plastic is used to mold the deflector, such as polycarbonate. A thickness 1004 of the facet 700 varies monotonically between flange thickness 1000 and a thickness 1002 of region 1006. Thickness 1004 increases as a function of the distance away from the flange/end portion margin 614, and also increases as a function of the distance away from end portion edge 704 (FIG. 9).

[0045] As seen in FIGS. 11 and 12, the facet 700 has a surface 1100 that is at an angle to end portion edge 704 and to a surrounding portion 1200 of inner surface 702 that bounds facet 700. This angle permits the facet 700 to perform its camming function when a top edge of the window glass 108 impacts it. While in the illustrated embodiment the camming facet surface 1100 is substantially flat, in other embodiments it may be curved and may be more smoothly continuous with surrounding inner surface portion 1200.

[0046] FIG. 13 is a yz sectional view of main deflector portion 602, with the section taken well away from end portions 608 or 610. The deflector body 600 has a substantially uniform thickness. An outboard surface 1300 of main portion 602 has a lower segment 1302 that is concavely curved relative to vehicle center C. Segment 1302 extends from lower edge 606 to a margin 1304 with an upper segment 1306 thereof. Segment 1306 in turn extends from junction 1304 to body upper margin 604, and is convexly recurved relative to center C. The radius of curvature of upper segment 1306 can be about 1.5 to about 6 mm and in one embodiment is about 1.65 mm. An outboard surface 1309 of flange 616 begins at main portion upper margin 604 and continues to an upper flange edge 1311.

[0047] In a similar fashion, an inboard surface 1308 of main portion 602 has a lower segment 1310 that extends from lower edge 606 to a margin 1312. Lower segment 1310 is concavely curved relative to vehicle center C. An upper segment 1314 of inboard surface 1308 extends from margin 1312 to body upper margin 604, and is convexly recurved relative to vehicle center C. A radius of curvature of upper segment 1314 can be about 5 mm. An inboard surface 1316 of flange 616 upwardly continues from main portion upper margin 604 to flange edge 1311. The curving and recurving of body main portion 602 provides a smooth transition to flange 616. This makes the joint 604 between the flange 616 and the body 602 more capable of withstanding a tangential force or bending stress tending to separate body 600 from flange 616. Replacing an otherwise abrupt junction with one having smooth curved transitions also improves aesthetics.

[0048] These smooth, curved and recurved transitions also appear in each capped end portion of the deflectors. FIG. 14 is a longitudinal sectional view through forward end portion 610 and flange 616. End portions 410 and 608 are similar and mirror-imaged in section. The end portion 610 has an inner surface 1400 with a first outboard segment 1402 that extends from a margin 1404 with main portion inboard surface 1308 to a margin 1405 with a second, inboard segment 1406. The first surface segment 1402 is concavely curved in an xy plane with respect to main portion center 630 (FIG. 8). The second surface segment 1406 extends from its margin 1404 with first surface segment 1402 to an end portion margin 1408 that it makes with inboard flange surface 1316. The second surface segment 1406 is convexly recurved in a direction opposite that taken by segment 1402.

[0049] Similarly, an outer surface 1410 of end portion 610 has a first, outboard segment 1412 that extends from its margin 1414 with outer surface 1416 of main portion 602 to a margin 1418 with a second, inboard surface segment 1420. First segment 1412 is concavely curved relative to main portion center 630 and in an xy plane. Second, inboard surface segment 1420 extends from its margin 1418 with first surface segment 1410 to a margin 1422 with the outboard flange surface 1309. Inboard surface segment 1420 is convexly recurved in a direction of curvature opposite that taken by outboard surface segment 1412 and in an xy plane. A radius of curvature of inboard surface segment 1420 may be in the range of about 2 mm to about 25 mm, and in one embodiment is about 19 mm. The curved and recurved smooth transition of the end portion 610 to flange 616, and the corresponding curved and recurved smooth transitions of end portions 410 and 608 to their respective flanges, makes the deflectors more capable of withstanding bending stress between their end portions and their flanges. It also improves the aesthetics of the deflectors.

[0050] In one embodiment, the radius of curvature of the inboard surface segment 1420 of end portion 610 is significantly greater than the radius of curvature of the main portion outboard upper surface segment 1306 (FIG. 13). As one transitions from main portion surface segment 1306 to end portion surface segment 1420, the radius of curvature will smoothly increase. A similar smooth variance in radii of curvature will also occur at the transitions between main portion 602 and end portion 608 of the rear deflector 114, and between main portion 404 and end portion 410 of front deflector 112.

[0051] FIGS. 15A and 15B are details showing the interaction of an advancing top edge 1500 of the rear glass pane 108 with the rear end portion camming facet 700 and the front end portion camming facet 706 of rear window deflector 114. In these views, the deflector has been installed in a channel in the door frame, an outer panel of which is schematically shown at 1502. The outboard surface 1309 of flange 616 may be attached to the window channel 1502 with adhesive or the like. As glass edge 1500 advances upward, the first structures of deflector 114 which it will encounter will be camming facets 700 and 706. Once edge 1500 contacts facets 700 and 706, edge 1500 will cam or slide along their surfaces, easing the upward progression of window pane 108 until window pane 108 is in the fully raised position seen in FIG. 16. The advancing top edge of front window glass 106 will have a similar interaction with front deflector camming facet 424.

[0052] In summary, side window deflectors have been shown and described which have curved and recurved transitions between the outer surfaces of their flanges and their bodies. Each deflector body further has at least one camming facet on its inboard surface that eases the upward progress of the edge of the window glass so that the window glass may be easily seated in its respective frame channel.

[0053] While illustrated embodiments of the present invention have been described and illustrated in the appended drawings, the present invention is not limited thereto but only by the scope and spirit of the appended claims.
