Japanese Patent Laid-Open No. 11-62442 JP 2005-335484 A

  As in the conventional example described above, in the electric rear sunshade, the sunshade is pulled out to the upper side of the vehicle through a slit-like opening provided in the rear package tray trim, and the retracted state is drawn by being pulled downward of the vehicle. Become. In the retracted state, the opening of the rear package tray trim is covered by the frame at the upper end of the sunshade.

  However, when the lower end side of the rear window is formed wider than the upper end side, if the area covering the rear window with the sunshade is increased, the sunshade also has a shape whose lower end side is wider than the upper end side. The length of the opening of the rear package tray trim is set so that the wide lower end of the sunshade can also pass. Therefore, since the length of the frame at the upper end of the sunshade is shorter than the length of the opening of the rear package tray trim, it is not possible to cover all the openings of the rear package tray trim with the upper end frame when the sunshade is stored. The left and right ends of the opening are exposed.

  In view of the above facts, an object of the present invention is to improve the appearance by preventing the opening of the rear package tray trim from being exposed when the sunshade is retracted.

  According to a first aspect of the present invention, there is provided a sunshade for a rear window, which is provided below the rear package tray trim and is electrically driven through an opening formed in the rear package tray trim and has a lower end wider than an upper end. A frame provided at the upper end of the sunshade and covering the opening when the sunshade is stored; and a frame provided at both ends of the frame and covering a range of the opening that is not covered by the frame when the sunshade is stored. And a cover.

  In the electric rear sunshade according to the first aspect, all the openings of the rear package tray trim are covered by the frame at the upper end of the sunshade and the covers at both ends of the frame when the sunshade is retracted. For this reason, both ends of the opening are not exposed in a slit shape, and the appearance is good.

  According to a second aspect of the present invention, in the electric rear sunshade according to the first aspect, the cover is rotatably provided with respect to the frame and is urged to rotate in a direction along a side end of the sunshade. The rear package tray trim is provided with a guide portion for guiding the cover so as to rotate and displace outside the vehicle against the biasing force when the sunshade is stored.

  In the electric rear sunshade according to the second aspect, the covers at both ends of the frame are rotated in a direction along the side end of the sunshade by the rotation bias when the sunshade is used, and are folded. Thereby, when the sunshade is used, the overhang of the cover from both ends of the frame is suppressed, so that the appearance is good.

  Further, when the sunshade is stored, the covers at both ends of the frame are guided by the guide portion provided in the rear package tray trim, and are rotationally displaced to the outside of the vehicle against the urging force against the cover. As a result, the cover projects from both ends of the frame to the outside of the vehicle, so that the range of the opening of the rear package tray trim that is not covered by the frame is covered.

  Thus, in the electric rear sunshade according to the second aspect, not only when the sunshade is stored, but also the appearance during use can be improved.

  According to a third aspect of the present invention, in the electric rear sunshade according to the second aspect, at least one of the frame and the cover is arranged such that the cover is in a state along the side edge of the sunshade when the sunshade is used. A stopper is provided for restricting the angular position of the cover.

  In the electric rear sunshade according to claim 3, the covers at both ends of the frame rotate in a direction along the side edge of the sunshade by rotation bias when the sunshade is used. Alternatively, the cover is regulated so as to be in a state along the side edge of the sunshade by a stopper provided on at least one of the covers. As a result, the cover is stably folded at a predetermined angular position along the side edge of the sunshade. For this reason, the presence of the cover is not conspicuous when the sunshade is used, and the appearance is good.

  As described above, according to the electric rear sunshade according to claim 1 of the present invention, it is possible to improve the appearance by preventing the opening of the rear package tray trim from being exposed when the sunshade is stored. An excellent effect is obtained.

  According to the electric rear sunshade described in claim 2, it is possible to obtain an excellent effect that not only the sunshade is stored but also the appearance at the time of use can be improved.

  According to the electric rear sunshade according to the third aspect of the present invention, it is possible to obtain an excellent effect that the presence of the cover when the sunshade is used is not noticeable and the appearance is good.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In FIG. 1, an electric rear sunshade 10 according to the present embodiment is a light shielding device used for the purpose of blocking outside light entering the vehicle through a rear window 14 of a vehicle 12, and includes a sunshade 16, a frame 18, And a cover 20.

  1 and 2, the sunshade 16 is, for example, a curtain-like body for the rear window 14 and is provided below the rear package tray trim 22 and is electrically driven through an opening 24 formed in the rear package tray trim 22. It is configured to be put in and out. The sunshade 16 is a cloth curtain having a visible light transmittance of, for example, about 30%, and is formed in a trapezoidal shape, for example, in a front view corresponding to the substantially trapezoidal rear window 14. Accordingly, the lower end 16L of the sunshade 16 is wider than the upper end 16U. The side end 16B of the sunshade 16 is formed, for example, in a straight line so as to connect the ends of the upper end 16U and the lower end 16L. Note that the shape of the side end 16B of the sunshade 16 is not limited to a linear shape, and a part or all of the shape may be a curved shape.

  The frame 18 is a member that is provided at the upper end 16U of the sunshade 16 and holds the upper end 16U. The frame 18 covers, for example, most of the opening 24 of the rear package tray trim 22 when the sunshade 16 is stored. A range of the opening 24 that is not covered with the frame 18 is covered with a cover 20 described later.

  As shown in FIGS. 1 and 2, a pair of arms 26 are connected to the vehicle lower side of both end portions 18 </ b> A of the frame 18. Each arm 26 has a folded structure, and the upper arm 26A and the lower arm 26B are connected to each other by, for example, pins 30 so as to be relatively rotatable. As shown in FIG. 4, the upper end 26 </ b> U of the upper arm 26 </ b> A is pivotally supported by, for example, a pin 28 on the vehicle lower side of both end portions 18 </ b> A of the frame 18. Thereby, the upper arm 26 </ b> A is rotatable with respect to the frame 18.

  The lower end of the lower arm 26 </ b> B is pivotally supported by a portion (not shown) below the rear package tray trim 22. The arm 26 extends, for example, in a straight line when the sunshade 16 is used, and when the sunshade 16 is retracted, the left and right lower arms 26B are respectively tilted inward in the vehicle width direction, so It is folded in a convex manner toward the center, and is stored entirely through the opening 24 below the rear package tray trim 22. In order to drive the arm 26 in this way, a drive device (not shown) that swings the lower arm 26B is provided below the rear package tray trim 22. This driving device is controlled so that the lower arm 26 </ b> B is raised when the sunshade 16 is used and is tilted when the sunshade 16 is retracted.

  Note that the arm 26 is not limited to the one having a bent structure, and may be a structure in which the upper end 26U is slidably connected to the frame 18 in the longitudinal direction of the frame 18, for example. In the case of this structure, as the arm 26 swings, the upper end 26U slides in the longitudinal direction of the frame 18 so that the frame 18 moves up and down.

  A roller (not shown) capable of winding the sunshade 16 is provided below the rear package tray trim 22. The roller is biased in the winding direction of the sunshade 16 by, for example, a coil spring (torsion spring), and applies an appropriate tension to the sunshade 16 when the sunshade 16 is pulled out and stored. Yes. By applying tension to the sunshade 16, fluttering of the sunshade 16 can be suppressed.

  The opening 24 of the rear package tray trim 22 is formed linearly, for example, along the vehicle width direction. The frame 18 is also formed in a straight line corresponding to the opening 24. The width of the opening 24 is set so that the sunshade 16 and the arm 26 can pass through. The length of the opening 24 is set to be longer than the length of the frame 18 that holds the upper end 16U so that the lower end 16L of the sunshade 16 can pass through.

  Next, in FIGS. 1 to 4, the cover 20 is a member that is provided at both ends 18 </ b> A of the frame 18 and covers a range of the opening 24 that is not covered by the frame 18 when the sunshade 16 is stored. As shown in FIG. 4, the cover 20 is folded along the side end 16 </ b> B of the sunshade 16 when the sunshade 16 is in use. The cover 20 is made of, for example, synthetic resin, and is formed in a substantially U-shaped cross section, for example, by a pair of front and rear vertical wall portions 20A and a side wall portion 20B connecting the pair of vertical wall portions 20A in the vehicle front-rear direction. Yes. As shown in FIG. 4, when the sunshade 16 is in use (the cover 20 is in a folded state), the side wall portion 20B is located at the outer edge in the vehicle width direction of the pair of vertical wall portions 20A.

  Further, as shown in FIG. 6B, in the retracted state of the sunshade 16, the side wall portion 20B is located at the vehicle upper edge of the pair of vertical wall portions 20A, and is flush with the upper surface 18B of the frame 18, for example. It is set to be. The separation distance between the pair of front and rear vertical wall portions 20A is set to be slightly larger than the front and rear width of both end portions 18A of the frame 18, and the both end portions 18A are located between the pair of vertical wall portions 20A. The cover 20 is provided so as to be rotatable with respect to the frame 18 by a pin 32 penetrating the pair of vertical wall portions 20A and both end portions 18A.

  Further, the cover 20 is urged to rotate in the direction along the side end 16B of the sunshade 16 (in the direction of arrow A) by, for example, a torsion coil spring 34. The torsion coil spring 34 is provided on the same axis as the pin 32. One end 34 A of the torsion coil spring 34 is fixed to the frame 18, and the other end 34 B is fixed to the cover 20.

  Of the vertical wall portion 20A of the cover 20, a curved portion 20C is formed at an end portion located on the vehicle lower side when the sunshade 16 shown in FIG. 4 is used (the cover 20 is folded). In the vertical wall portion 20A, the curved portion 20C is formed in, for example, an arc shape from the end edge 20E on the side wall portion 20B side to the end edge 20D on the opposite side to the side wall portion 20B. The center of curvature (not shown) of the curved portion 20C is located on the side wall portion 20B side. At the boundary between the edge 20D and the curved portion 20C, the edge 20D is tangent to the curved portion 20C.

  As shown in FIG. 6 (A), the rear package tray trim 22 is guided so that the cover 20 is rotationally displaced to the outside of the vehicle against the biasing force of the torsion coil spring 34 when the sunshade 16 is stored. A guide portion 36 is provided. The guide portion 36 is formed in a concave shape corresponding to the shape of the curved portion 20C, and the portion with which the curved portion 20C of the cover 20 first contacts when the sunshade 16 is retracted is directed outward in the vehicle width direction. The slope 36A is directed obliquely downward. The slope 36B connected to the outside of the slope 36A is directed obliquely upward toward the outside in the vehicle width direction. Further, as shown in FIG. 6 (B), the slope 36C connected to the outside in the vehicle width direction of the slope 36B is such that the side wall portion 20B of the cover 20 is along the longitudinal direction of the frame 18 in the retracted state of the sunshade 16 18B). The contours of the slope 36C and the curved portion 20C may coincide.

  Next, as shown in FIGS. 3A and 4, at least one of the frame 18 and the cover 20 is arranged so that the cover 20 is in a state along the side end 16 </ b> B of the sunshade 16 when the sunshade 16 is used. A stopper 38 for restricting the angular position of the cover 20 is provided. In the present embodiment, the stopper 38 is provided as a local protrusion on the end surfaces of both end portions 18 </ b> A of the frame 18.

  The shape of the stopper 38 is not limited to this. For example, as shown in FIG. 5, the end surfaces of both end portions 18 </ b> A of the frame 18 may be inclined surfaces that project outward in the vehicle width direction toward the vehicle lower side, and the maximum projecting position may be used as the stopper 38. Further, a stopper may be provided on the cover 20 side, and a stopper may be provided on both the frame 18 and the cover 20 (none of which is shown). Further, the angular position of the cover 20 may be regulated by the cover 20 coming into contact with the upper arm 26 </ b> A of the arm 26. In this case, the arm 26 also serves as a stopper, and the cost can be reduced compared to the case where the frame 18 and the cover 20 are provided with a stopper.

(Function)
This embodiment is configured as described above, and the operation thereof will be described below. First, the operation of the sunshade 16 in the electric rear sunshade 10 will be described. 1 and 2, when the sunshade 16 is used, a driving device (not shown) swings the lower arms 26B of the pair of arms 26 in the direction of arrow U (FIG. 2). As a result, the upper arm 26A and the lower arm 26B rotate relative to each other about the pin 30, and the arm 26 extends, whereby the frame 18 rises and the sunshade 16 held by the frame 18 moves to the rear. It is pulled out through the opening 24 of the package tray trim 22 and developed along the rear window 14. At this time, the sunshade 16 is fed out while maintaining an appropriate tension from a roller (not shown). The sunshade 16 drawn out in this manner can appropriately block outside light entering the vehicle through the rear window 14.

  As shown in FIG. 4, the cover 20 at both ends of the frame 18 is urged to rotate in the direction of arrow A by the torsion coil spring 34. It rotates in the direction (arrow A direction), and it will be in the folded state. The angular position of the cover 20 at this time is determined by the stopper 38 provided on the end face of the both ends 18A of the frame 18 in this embodiment. To be in a state along the line. The same applies to the example shown in FIG.

  Thereby, the cover 20 is stably folded at a predetermined angular position along the side end 16B of the sunshade 16, and the side wall 16B of the sunshade 16 and a part of the upper arm 26A are formed by the vertical wall portion 20A of the cover 20. Will be covered. For this reason, when the sunshade 16 is used, the overhanging of the cover 20 from both end portions 18A of the frame 18 is suppressed, so that the presence of the cover 20 is not noticeable and the appearance is good. Furthermore, the rear view from a passenger (not shown) is also improved.

  In addition, when the extended arm 26 is configured along the side end 16 </ b> B of the sunshade 16, the folded cover 20 is also in the state along the arm 26. Since the longitudinal direction of the cover 20 and the longitudinal direction of the arm 26 are aligned in parallel, the cover 20 becomes less conspicuous and the appearance is further improved. Further, from the viewpoint of appearance, it is desirable that the step between the side wall portion 20B of the cover 20 and the arm 26 in the front view be as small as possible.

  Next, the operation of the electric rear sunshade 10 when the sunshade 16 is stored will be described. When storing the used sunshade 16 shown in FIGS. 1 and 2, a driving device (not shown) swings the lower arms 26B of the pair of arms 26 in the direction of arrow D (FIG. 2). As a result, the arm 26 is folded about the pin 30 so that the frame 18 is lowered. At this time, the sunshade 16 held by the frame 18 is wound down below the rear package tray trim 22 through the opening 24 of the rear package tray trim 22 while being given an appropriate tension by a roller (not shown). Go.

  Subsequently, as shown in FIG. 6A, when the frame 18 approaches the opening 24 of the rear package tray trim 22, the curved portion 20C of the cover 20 is provided in the rear package tray trim 22. It abuts on the slope 36A of the guide portion 36. Since this slope 36A has a shape that goes obliquely downward toward the outer side in the vehicle width direction, the cover 20 slides on the slope 36A as the frame 18 further descends. By going, the rotational displacement of the torsion coil spring 34 (FIGS. 4 and 5) is carried out to the vehicle outer side (vehicle width direction outer side) with the pin 32 as the center.

  The curved portion 20C of the cover 20 slides on the slopes 36B and 36C following the slope 36A, and further rotationally displaces to the outside of the vehicle and protrudes outward in the vehicle width direction. As shown in FIG. 6B, when the frame 18 is completely lowered and the sunshade 16 is stored, the side wall portion 20B of the cover 20 extends along the longitudinal direction of the frame 18 and, for example, a rear package tray. It is flush with the surface of the trim 22 and the upper surface 18B of the frame 18.

  As shown in FIG. 2, the sunshade 16 is formed in a substantially trapezoidal shape, and since the upper end 16U is shorter than the lower end 16L, all the openings 24 of the rear package tray trim 22 are opened by the frame 18 provided at the upper end 16U. Although it cannot be covered (see FIG. 8A), most of the opening 24 is still covered with the frame 18. As shown in FIGS. 7 and 8B, the range of the opening 24 that is not covered by the frame 18 is covered by the cover 20 that protrudes from the both ends 18A of the frame 18 to the outside of the vehicle.

  As described above, in the present embodiment, in the retracted state of the sunshade 16, the frame 18 and the cover 20 at both ends 18 </ b> A of the frame 18 cover all the openings 24 of the rear package tray trim 22. For this reason, both ends of the opening 24 are not exposed in a slit shape, and the appearance is good. Since the cover 20 is folded along the side edge 16B of the sunshade 16 when the sunshade 16 is used, not only the sunshade 16 but also the appearance during use can be improved.

  6A and 6B, in this embodiment, when the sunshade 16 is stored, the curved portion 20C of the vertical wall portion 20A of the cover 20 contacts the guide portion 36. The end edge 20D is configured not to contact the guide portion 36, but may be configured to contact the guide portion 36 from the curved portion 20C to the end edge 20D. As shown in FIGS. 4 and 5, at the boundary between the edge 20D of the vertical wall portion 20A and the curved portion 20C in the cover 20, the edge 20D forms a tangent to the curved portion 20C. Even when the guide 20 is in contact with the edge 20D from the portion 20C, the cover 20 can be smoothly rotated and displaced along the guide 36. Accordingly, when the cover 20 is guided by the guide portion 36 when the sunshade 16 is raised or lowered, abnormal noise or the like hardly occurs.

  Moreover, it is good also as a structure which does not provide the guide part 36. FIG. If the cover 20 is along the side end 16B of the trapezoidal sunshade 16, the cover 20 protrudes outside the vehicle in the vertical direction, and the curved portion 20C of the vertical wall portion 20A is the surface of the rear package tray trim 22. This is because the cover 20 can be rotationally displaced to the outside of the vehicle as the sunshade 16 is retracted by sliding on the top.
