FIG. 10 is a rear view of FIG. 4 is an enlarged perspective view of a main part of the sunshade device, FIG. 5 is a side view schematically showing a state in which the curtain body is wound and the light shielding plate (molded plate) is lying down, and FIG. FIG. 7 is a side view schematically showing a state in which the curtain body is unfolded and the light-shielding plate (molded plate) is raised, and FIG. 7 is a diagram schematically showing an example of a coil spring (which constitutes a winding member). 8 is a diagram schematically showing an example of a torsion spring (which constitutes an urging member).

  As shown in FIG. 1, a package tray 3 is disposed at the rear upper part of the rear seat 2 of the vehicle 1, and a sunshade device 10 is installed at the rear of the package tray 3. As shown in FIGS. 2 and 3, the sunshade device 10 includes a curtain body (shade) 12 made of a flexible sheet-like member, and the curtain body 12 is disposed on the surface of the rear window W on the vehicle interior side. The vehicle interior side of the rear window W of the vehicle 1 can be covered by deploying along

  As the sheet-like member constituting the curtain 12, for example, a translucent sheet, an opaque sheet, a mesh sheet, a woven fabric, a non-woven fabric, or the like can be used. As a material for such a sheet-like member, for example, a synthetic resin material such as polyvinyl chloride or polypropylene can be used.

In addition, the sunshade device 10 includes a shaft 14 and a coil spring 60 (see FIG. 7) for winding up the curtain body 12, and a case 16 that accommodates the shaft 14.
The shaft 14 is constituted by a cylindrical member capable of winding the curtain body 12 around it, and is housed in the case 16 in a form of being urged in a winding direction by a coil spring 60. The curtain 12 can be wound around the shaft 14. The shaft 14 is formed of a synthetic resin material such as polypropylene or a metal material such as aluminum or iron.

  The case 16 is configured by a rectangular tube-like member that can accommodate the shaft 14 in a rotatable state. The case 16 is made of, for example, a synthetic resin material such as polypropylene, or a metal material such as aluminum or iron. On the upper side of the case 16, an opening 18 for drawing the curtain 12 upward is provided.

  A light shielding plate 32 and a frame 20 made of a long plate-like member are disposed on the upper end portion of the curtain body 12. Specifically, a light shielding plate 32 is attached to the end of the curtain body 12, and the frame 20 is connected to the light shielding plate 32.

  The frame 20 is made of, for example, a synthetic resin material such as polypropylene, or a metal material such as aluminum or iron. The frame 20 makes it possible to hold the curtain body 12 made of a flexible member in a state where the curtain body 12 is deployed in the vehicle width direction, and the curtain body 12 is deployed or wound as the frame 20 is pulled out or pulled back. It has been taken.

  A movable piece 22 made of a long plate-like member is attached to each of the left and right ends of the frame 20. The movable piece 22 is slidably inserted into sliding holes 21 formed at both left and right ends of the frame 20. A slider 24 is connected to the tip of the movable piece 22. The slider 24 is formed of a synthetic resin material having excellent sliding performance, such as POM (polyacetal), and the movable piece 22 is rotatably connected to a connecting shaft 24a erected on the upper surface thereof.

  On both sides of the rear window W, a pair of guide rails 26a and 26b made of a long member having a substantially U-shaped axial section is attached. The pair of guide rails 26a, 26b is formed of, for example, a metal material such as iron or aluminum, and is disposed along both sides of the rear window W.

  Further, the slider 24 is slidably fitted in the inside of each of the pair of guide rails 26a and 26b so as to be slidable in the vertical direction, thereby guiding the slider 24 and eventually the frame 20 in the pulling direction. It is supposed to be. The guide rails 26a and 26b are linear in the sliding direction of the slider 24, that is, the pulling direction of the frame 20, and further, the vehicle width is set so that the mutual distances approach each other along the pulling direction of the frame 20. It is arranged so as to be inclined inward in the direction.

  A light shielding plate (molded plate) 32 is connected to the frame 20 via a rotating shaft 33 and a torsion spring 40 wound around the rotating shaft 33 as shown in FIG. The light shielding plate 32 is configured to be freely inverted when the frame 20 is pulled back or pulled out. That is, the light shielding plate 32 is always urged by the torsion spring 40 in the direction in which the light shielding plate 32 is tilted, specifically, the direction substantially along the surface of the window portion W, and the torsion spring 40 is attached to the light shielding plate 32. When force is applied in the direction against the power, it stands up. The light shielding plate 32 is made of a synthetic resin material such as polypropylene, or a metal material such as aluminum or iron, and is formed in an arc shape so that the upper side portion 32a is along the vehicle interior ceiling surface R. Yes.

  The light shielding plate 32 is connected to the shaft 14 as a winding member. Specifically, the light shielding plate 32 and the shaft 14 are connected via the curtain body 12, and the connection between the light shielding plate 32 and the shaft 4 in this case is an urging force (that is, applied to the light shielding plate 32). The urging force of the torsion spring 40 and the winding force of the shaft 14 by the coil spring 60 act in opposite directions through the curtain body 12.

  On the other hand, the coil spring 60 constituting the winding member has a winding force that increases as the curtain body 12 is expanded, that is, as the slider 24 (frame 20) is pulled out along the guide rails 26a and 26b. Specifically, the winding force is maximized when the curtain body 12 is unfolded (FIGS. 3 and 6), and the winding force is maximized when the curtain body 12 is wound (FIGS. 2 and 5). Be minimized.

  As described above, the urging force of the torsion spring 40 and the winding force of the coil spring 60 are forces acting in opposite directions. In particular, the urging force of the torsion spring 40 is the winding force in the winding state of the curtain body 12 (the retracted state of the frame 20 (FIGS. 2 and 5)) where the winding force of the coil spring 60 is minimum. As a result, the light-shielding plate 32 is in a lying state because the biasing force is greater than the winding force. On the other hand, in the deployed state of the curtain body 12 where the winding force of the coil spring 60 is maximum (the frame 20 being pulled out (FIGS. 3 and 6)), the winding force is superior to the urging force (the urging force). Thus, the light shielding plate 32 stands up against the urging force of the torsion spring 40. In this standing state, the light shielding plate 32 can realize sufficient light shielding with respect to the vehicle interior.

In the following, a mechanism for performing the drawing (developing) and winding operation of the curtain body 12 by moving the frame 20 in the vertical direction will be described with reference to FIG.
As shown in FIG. 2, a motor M is disposed below the rear window W, and a pinion gear 28 is attached to a drive shaft of the motor M. The pinion gear 28 meshes with a geared wire 30 that is driven in the vertical direction along the inside of the pair of guide rails 26a and 26b as the pinion gear 28 rotates. The slider 24 is attached to the tip of the geared wire 30.

  Therefore, when the pinion gear 28 rotates forward or backward by the driving force of the motor M, the slider 24 attached to the tip of the geared wire 30 is driven upward or downward along the inside of the pair of guide rails 26a and 26b. Thereby, it is possible to move the frame 20 attached to the slider 24 through the movable piece 22 in the vertical direction.

  As described above, the upper ends of the pair of guide rails 26a and 26b are inclined toward the inner side in the vehicle width direction. Therefore, when the frame 20 is moved in the vertical direction, the distance between both ends of the frame 20 and the pair of guide rails 26a and 26b changes. Since the movable piece 22 is attached, the movable piece 22 can absorb such a change in distance by sliding in the vehicle width direction.

  By the mechanism as described above, the curtain body 12 is unfolded or wound as the frame 20 is pulled out or pulled back. The inverted state of the light shielding plate 32 changes as the frame 20 is pulled out (deployment of the curtain body 12) or pulled back (winding up the curtain body 12).

  That is, when the frame 20 is pulled back (the curtain body 12 is wound), the winding force of the coil spring 60 is weakened, and the urging force of the torsion spring 40 becomes the winding force as shown in FIG. The light shielding plate 32 is laid down by the biasing force. On the other hand, in a state where the frame 20 is pulled out (a state in which the curtain body 12 is deployed), the winding force of the coil spring 60 becomes strong, and the winding force becomes the urging force of the torsion spring 40 as shown in FIG. As a result, the light shielding plate 32 is erected by the urging force applied to the light shielding plate 32 being weakened, thereby realizing a light shielding function for the vehicle interior.

  Thus, in this embodiment, since the light shielding plate 32 stands up as the frame 20 is pulled out, and the light shielding plate 32 falls down when the frame 20 is pulled back, the smooth shielding of the light shielding plate 32 is realized. Therefore, the light shielding plate 32 can be rotated (inverted) regardless of the shape of the guide rails 26a and 26b (the shape along the drawing direction of the light shielding plate 32), and the linear guide rail as in the present embodiment. Even if it is 26a, 26b, the light-shielding plate 32 can be rotated (inverted). Therefore, it is possible to save space compared to curved guide rails, and it is difficult to generate or deteriorate operating noise due to sliding or sliding resistance in curved guide rails, and there is no need for bending and other costs. Reduction is realized.
