Description

Technical field

[0001] This disclosure concerns a wind deflector device. State of the art

[0002] In the prior art, JP 2006-168439A discloses a wind deflector device that prevents air vibrations caused by the intake of wind into a passenger compartment when a roof opening section provided in the roof of a vehicle is open.

[0003] JP 2006-168439A describes a wind deflector device comprising a wind deflector arm that rotates to approach and detach from a sunshade rail located along a roof opening, in conjunction with the opening and closing operations of a sliding panel that opens and closes the roof opening. In an opening operation, the wind deflector device is configured to release and rotate the wind deflector arm to detach from the sunshade rail, and a wind deflector blade is deployed in conjunction with the rotation of the wind deflector arm. In a closing operation, the wind deflector arm is further configured to depress and rotate to approach the sunshade rail, and the wind deflector blade is deployed in conjunction with the rotation of the wind deflector arm.The wind deflector device of JP 2006-168439A includes a leaf spring that pre-tensions the wind deflector arm in a direction separate from the sunshade rail.

[0004] In the wind deflector device of JP 2006-168439A, one end of a leaf spring is attached to a base element that is mounted on a sunshade rail. The other end of the leaf spring is inserted from the side of the sunshade rail into a recess with an opening on the side of the sunshade rail, extending along one direction of travel of the wind deflector arm. Accordingly, the leaf spring slides in a state where it is in line contact with the bottom of the wind deflector arm recess as the arm rotates. In another state, the leaf spring slides in a state where it is in surface contact with the side wall of the wind deflector arm recess. If the sliding resistance increases as the wind deflector arm rotates, there is a risk that the sliding noise will increase.

[0005] DE 10 2005 033 431 B4 discloses a device with a (support) arm that carries a wind deflector unit at its front end. The arm is pivotally mounted at its rear end along a pivot axis running parallel to a leading edge of a roof opening, enabling the arm to tilt and pivot. The pivot axis of the arm is movable in the longitudinal direction of the vehicle by a torsion spring, which biases the arm in the tilting direction during tilting and pivoting. The torsion spring is mounted on a vehicle roof and in a central region of the arm.

[0006] DE 10 2010 048 457 B4 discloses a wind deflector for a vehicle roof, which has an air guide profile equipped with or hinged to lateral extension arms, which can be extended into an operating position by the force of a spring device and lowered into a rest position against the force of the spring device. The spring device comprises at least one U-shaped wire loop spring with two spring legs, which are connected to each other at one end and whose other ends are supported on offset bearings, and the two bearings are held fixed relative to each other.

[0007] Therefore, there is a need for a wind deflector device that can reduce sliding resistance when a wind deflector arm rotates. Summary

[0008] According to one aspect of this invention, a wind deflector device comprises: a wind deflector base attached to both side edge sections of a roof opening section provided in the roof of a vehicle; a wind deflector arm mounted on the wind deflector base to extend along both side edge sections of the roof opening section and rotatably mounted to approach and detach from the roof opening section in response to an opening and closing operation of a panel for opening and closing the roof opening section; a wind deflector unit configured to be deployed in a case where the wind deflector arm is detached from the roof opening section and to be stored in a case where the wind deflector arm is approaching the roof opening section;and a prestressing element installed in a state in which it rests against the wind deflector arm, such that its end face is mounted on the wind deflector base and its other end face is movably resting against the wind deflector arm to prestress the wind deflector arm in a direction in which the wind deflector arm is separated from the roof opening section, wherein the prestressing element is a wire material bent as a whole into a U-shape such that its two pointed ends approach each other, and is installed such that both pointed ends of the wire material become one end face and a U-shaped portion in which portions extending from each pointed end connect to each other becomes the other end face.

[0009] According to the configuration described above, part of the preload element that rests against the wind deflector arm is a U-shaped

[0010] The return / bend section is a portion of the wire material bent into a U-shape. In other words, as the wind deflector arm rotates, the preload element slides in a state where it is in point contact with the wind deflector arm at the U-shaped section. Because the wire material is used as the preload element in the configuration described above, the sections themselves, in a case where the portions extending from both tip ends each come into contact with the wind deflector arm, do not make surface contact with the wind deflector arm, but do make line contact with it. In this case, for example, the sliding area between the preload element and the wind deflector arm can be reduced compared to a case where a leaf spring is used as the preload element.Therefore, the sliding resistance can be reduced when the wind deflector arm rotates, and the sliding noise based on the rotation of the wind deflector arm can be reduced.

[0011] In the wind deflector device according to this aspect of the invention, it is preferred that the wind deflector arm is provided with a contact section which projects towards one side of the pretensioning element with respect to an end face opposite the pretensioning element, and the other end side of the pretensioning element rests against the wind deflector arm via the contact section.

[0012] According to the configuration described above, the portion of the wind deflector arm that rests against the U-shaped part of the prestressing element is limited to the contact area of ​​the wind deflector arm, that is, to the surface of the corresponding contact area. Accordingly, it is possible to maintain a condition of reduced sliding area between the prestressing element and the wind deflector arm in a suitable manner. Therefore, it is possible to appropriately reduce sliding resistance when the wind deflector arm rotates.

[0013] In the wind deflector device according to this aspect of the invention, it is preferred that the mounting section has an abutting part which rests against the pretensioning element while the wind deflector arm rotates, and a non-abutting part which does not rest against the pretensioning element, and the non-abutting part is configured such that its protrusion in the direction of the side of the pretensioning element is large compared to that of the mounting section.

[0014] For example, on an end face of the wind deflector arm opposite the pretensioning element, it is sufficient that at least the system section is provided on a part that rests against the pretensioning element when the wind deflector arm rotates, and the above effect can even be achieved if the system section is not provided on the part that does not rest against the pretensioning element.

[0015] In contrast, according to the configuration, the system section is also provided on a part that does not bear against the prestressing element when the wind deflector arm rotates, and for the non-bearing part of the system section, which corresponds to this, the system section is added as a reinforcing section, functioning as a so-called rib. Accordingly, the stiffness of the wind deflector arm can be increased.

[0016] In the wind deflector device according to this aspect of the invention, it is preferred that the wind deflector base has a pair of side walls opposite each other in a direction perpendicular to the direction in which the wind deflector arm extends, in which a pivot section extending forward of the opposite side wall and having an oval cross-sectional shape with a pair of opposing linear sections and a pair of opposing circular arc sections to connect the ends of the linear sections is provided in each side wall, wherein the wind deflector arm has a pivot section arranged between the side walls to be inserted into the pivot section of each side wall, wherein pivot holes, each having a depth of openings on sides of the opposite side walls in a direction,in which the side walls are opposite each other, in the rotating section are provided, and each of the axle journal holes has a tubular shape having an inner circumferential surface which is lubricated with a sliding surface, which is a surface of the pair of circular arc segments of the axle journal section, in an area larger than the area in which the wind deflector arm rotates, and has an insertion opening provided to allow the pair of linear segments of the axle journal section to pass through the inner circumferential surface in a radial direction in an area in which the wind deflector arm does not slide with the sliding surface when the wind deflector arm rotates to pass through the pair of linear segments of the axle journal section when it is inserted into the axle journal section, in the middle of the inner circumferential surface, and has a bottom wall provided toto block the openings between the sides of the side walls that are opposite each other, so that no one can pass through there.

[0017] According to the configuration, once the wind deflector device is mounted, the wind deflector arm can be attached to the wind deflector base by inserting a pair of linear sections of the stub section through the insertion opening of the stub hole. When the stub hole is inserted into the stub section, deformation of the pair of circular arc segments of the stub section and the insertion opening of the stub hole is prevented. Because the insertion opening of the stub hole is located in a region central to the inner circumferential surface that does not slide with the sliding surface of the stub section when the wind deflector arm rotates, the wind deflector arm is prevented from falling off the wind deflector base, even when the wind deflector arm is rotating.

[0018] Since the axle journal hole is additionally provided with the bottom wall in the configuration described above, the stiffness of the rotating section is increased compared to a case where the bottom wall is not provided. Accordingly, it is preferred that, even if the wind deflector arm rotates repeatedly, a widening of the insertion opening of the axle journal hole, a so-called entry opening, can be prevented, and a condition preventing the wind deflector arm from falling off the wind deflector base can be maintained. Therefore, the service life of the wind deflector device 20 can be increased, and its reliability can be improved.

[0019] In the wind deflector device according to this aspect of the invention, it is preferred that the wind deflector arm is mounted in a state in which the pivot section of each side wall of the wind deflector base is inserted into the pivot hole of the rotating section in such a way as to insert the preload element between the rotating section and the wind deflector base, and a part of the rotating section opposite the preload element is thin compared to other parts in order to bypass the preload element.

[0020] According to the configuration described above, the mounting space of the rotating section and the preload element can be enclosed by an amount corresponding to the reduced thickness of the rotating section. Consequently, the space required to mount the rotating section and the preload element can be reduced. This effectively miniaturizes the wind deflector base and, therefore, the wind deflector device itself.

[0021] In the wind deflector device according to this aspect of the invention, it is preferred that the axle pin section of each side wall has a pair of projection sections that project outwards in the radial direction with respect to a position on the diagonal of the sliding surface.

[0022] According to the configuration described above, when the wind deflector arm is mounted to the wind deflector base, the inner circumferential surface of the rotating section and the sliding surface of the pivot section are in contact via the protruding section provided on the sliding surface. In other words, any gap resulting from manufacturing and dimensional tolerances between the inner circumferential surface of the rotating section in the wind deflector arm and the pair of circular arc segments of the pivot section on each side of the wind deflector base can be eliminated. Consequently, when the wind deflector arm rotates, the generation of rattles is prevented, and smooth movement is achieved.

[0023] In the wind deflector device according to this aspect of the invention, it is preferred that when one end of the preload element is mounted, the wind deflector base has a first locking section and a second locking section, each of which locks both tip ends of the preload element and parts of both different tip ends separately.

[0024] According to the configuration, once the wind deflector device is mounted, the pretensioning element can be attached to the wind deflector base using the first and second locking sections. Since, in this case, not only can both ends of the pretensioning element be locked, but different parts of each end can be locked independently of the wind deflector arm, the pretensioning element can be attached to the wind deflector base independently. In this way, the function of independently attaching the pretensioning element to the wind deflector base itself is added to the existing attachment of the wind deflector base using the first and second locking sections. Therefore, it is not necessary to provide additional components for attaching the pretensioning element, thus reducing the number of components.In other words, the wind deflector device itself can be miniaturized.

[0025] Additionally, the wind deflector arm can be mounted flush with the wind deflector base in a state where the preload element is already attached, without having to worry about positional deviation of the preload element. In this case, it effectively improves the ease of installation of the wind deflector device.

[0026] According to the aspects of this invention, the sliding resistance can be reduced when the wind deflector arm rotates. Brief description of the characters

[0028] An embodiment of the wind deflector device is described below. Hereinafter, a forward and reverse direction of a vehicle is referred to as "forward and reverse direction", a lateral direction of a vehicle is referred to as "lateral direction", and an upward and downward direction of a vehicle is referred to as "upward and downward direction".

[0029] As in Fig. As shown in Figure 1, the roof 10 of a vehicle, such as an automobile, has a rectangular roof opening section 11. The roof 10 is equipped with a sunroof device 1, which has a panel 12 capable of opening and closing the roof opening section 11. The panel 12 is rectangular with a long side and a short side and is, for example, a glass panel. The panel 12 opens and closes the roof opening section 11 by actuation (opening and closing action) in the forward and reverse directions relative to the roof opening section 11. A sealing strip 13 is provided at a front edge section 11a and a rear edge section 11c, which are the circumferential edges of the roof opening section 11 and are opposite each other in the forward and reverse directions, and both side edge sections 11b are opposite each other in the width direction.The sealing strip 13 has the function of blocking a gap between the roof opening section 11 and the plate 12 in a state in which the roof opening section 11 is closed by the plate 12.

[0030] As in Fig. As shown in Figure 2, both side edge sections 11b of the roof opening section 11 are provided with guide rails 14, each having a pair of rail sections 14a extending along both side edge sections 11b in the forward and reverse directions. The leading edge section 11a is provided with a front housing 15 extending along the leading edge section 11a and connecting the front ends of the pair of guide rails 14 together in the lateral direction. A drive mechanism (not shown) for performing the opening and closing operation of the panel 12 is slidably mounted on the rail section 14a of each guide rail 14. The pair of guide rails 14 and the front housing 15 are provided with a wind deflector 20 such that they overlap in their upward direction.

[0031] Next, the configuration of the wind deflector device 20 will be described in detail. As in the Fig. 2 and Fig. As shown in Figure 3, the wind deflector device 20 has the front housing 15, that is, a lower frame 21 which is provided along the leading edge section 11a of the roof opening section 11. The lower frame 21 has a rod-like outer shell and is made of a resin material, such as polyethylene resin.

[0032] The lower frame 21 has a rod-like lower main body 22 that extends laterally along the leading edge section 11a. Strip-like mounting sections 23 are provided at both ends of the lower main body 22, extending rearward from both ends. A hub-shaped retaining projection 24, projecting outwards laterally, is provided at the tip of the mounting section 23. The retaining projections 24 are inserted through mounting holes (not shown) provided in the front housing 15. Thus, the lower frame 21 is attached to the front housing 15, i.e., the vehicle, by means of retaining projections 24 provided at both ends of the lower main body 22.

[0033] Additionally, the wind deflector device 20 is provided with a wind deflector frame 25, which can rotate (move vertically) to approach and separate itself from the roof opening section 11. The wind deflector frame 25 has an essentially C-shaped outer shell and is made, for example, of a resin material such as polyethylene resin.

[0034] The wind deflector frame 25 has a rod-like wind deflector main body 26, which extends laterally along the leading edge section 11a. The wind deflector main body 26 is opposite the lower main body 22 of the lower frame 21 in the upward and downward directions. At both ends of the wind deflector main body 26, a pair of wind deflector arms 27 is provided, each extending rearward from both ends along both side edge sections 11b.

[0035] Additionally, the wind deflector device 20 has a pair of prestressing elements 28 that individually prestress the pair of wind deflector arms 27 in such a way as to prestress the wind deflector frame 25 in a direction in which it separates from the roof opening section 11. The prestressing element 28 is a wire material having a circular cross-sectional area, such as copper, which is bent into a U-shape so that both pointed ends 28a approach each other.

[0036] The prestressing element 28 is in a state in which it is deflected completely from a central part in the direction of extension towards the roof opening section 11. A bending section 28c (or “R-section” with “R” for “return”), which is a U-shaped part, is provided on the opposite side of the two tip ends 28a of the prestressing element 28. Both tip ends 28a of the prestressing element 28 are bent like a key to extend in a direction opposite to the direction in which the pair of extension sections 28b bends.

[0037] Additionally, the wind deflector device 20 has a pair of wind deflector bases 29, to which a pair of wind deflector arms 27 and a pair of pretensioning elements 28 are individually mounted. The wind deflector base 29 is attached to the outside in the width direction of the rail section 14a on the side of the front housing 15 of the guide rail 14. The wind deflector base 29 has a rectangular parallelepiped shape with a long side and a short side extending along the guide rail 14 and is made, for example, of a resin material such as polyethylene resin.

[0038] As in Fig. As shown in Figure 4, the wind deflector base 29 is provided with a rectangular parallelepiped bearing section 30 having a long side and a short side, which is open to the front side, which is the side of the front housing 15, and to the upper side, which is opposite the side of the roof opening section 11 ( Fig. 2) A wind deflector arm 27 and a prestressing element 28 are each mounted on the bearing section 30.

[0039] In particular, the wind deflector arm 27 is mounted on the bearing section 30 such that it extends along both side edge sections 11b of the roof opening section 11. A pivot section 40, provided at the tip of the wind deflector arm 27, is rotatably installed in the wind deflector arm 27 with respect to the wind deflector base 29. Accordingly, the wind deflector arm 27 is rotatably mounted to approach and separate from the guide rail 14, which is provided along both side edge sections 11b, i.e., with respect to the roof opening section 11 via the pivot section 40.

[0040] Additionally, a prestressing element 28 is mounted in the bearing section 30 such that it is inserted between the wind deflector base 29 and the wind deflector arm 27. The prestressing element 28 is installed such that both pointed ends 28a, which are parts at one end, are locked to the wind deflector base 29. Furthermore, the prestressing element 28 is installed such that the bending section 28c, which is a part at the other end, rests against the wind deflector arm 27 on the side of the wind deflector base 29. Accordingly, the prestressing element 28 exerts a prestressing force on the wind deflector arm 27, thus prestressing the wind deflector arm 27 in a direction away from the roof opening section 11. The configurations described above can be applied equally to the wind deflector arm 27, the pretensioning element 28 and the wind deflector base 29 on the other side, as well as to the wind deflector arm 27, the pretensioning element 28 and the wind deflector base 29 on the side of area A, which is located in Fig. Apply as shown in section 3.

[0041] Additionally, as in the Fig. 2 and Fig. As shown in Figure 3, the wind deflector device 20 includes a wind deflector unit 50 for suppressing air vibrations caused by wind entering the passenger compartment. This unit is deployed when the roof opening section 11 is open. The wind deflector unit 50 is bridged between the lower frame 21 and the wind deflector frame 25 to connect them. The wind deflector unit 50 is belt-shaped and is a braided element woven in a mesh pattern, for example, with nylon or the like.

[0042] As in Fig. 5 shown, which depicts the end surface structure from Fig. As shown in Figure 2, a lower side connection section 50a, which forms one side of the wind deflector unit 50 in the width direction over its entire length in the longitudinal direction, is embedded on the lower main body 22 of the lower frame 21. A top connection section 50b, which forms the other side of the wind deflector unit 50 in the width direction over its entire length in the longitudinal direction, is embedded on the wind deflector main body 26 of the wind deflector frame 25. The connection sections 50a and 50b of the wind deflector unit 50 are formed integrally with the lower main body 22 and the wind deflector main body 26, for example by injection molding (insert molding).

[0043] As seen through the solid line in Fig. As shown in Figure 5, when the wind deflector frame 25 is released from the side of the plate 12 according to the opening process of the plate 12, the wind deflector arm 27 rotates due to the preload force of the preload element 28 (hereinafter referred to as the "upward movement") in order to be separated from the roof opening section 11 via the rotation section 40. In this case, the wind deflector main body 26 operates in such a way as to separate in the upward and downward directions with respect to the lower main body 22. Accordingly, the wind deflector device 20 operates to extend the wind deflector unit 50 in the lateral direction, which is the side direction, and to position the wind deflector device 50 to project from an upper surface 10a of the roof 10 (deployment process).

[0044] If, on the other hand, the wind deflector frame 25 is pressed downwards from the side of the plate 12 according to the closing process of the plate 12, as in Fig. As shown in Figure 5 by a two-dot single-dashed line, the wind deflector arm 27 rotates against the preload force of the preload element 28 (hereinafter referred to as the "downward movement") to approach the roof opening section 11 via the rotation section 40. In this case, the wind deflector main body 26 operates to approach the lower main body 22 in the upward and downward directions. Accordingly, the wind deflector device 20 operates to shorten the wind deflector device 50 in the lateral direction and to mount the wind deflector unit 50 so that it is received in the lower side (for example, the front housing 15) of the upper surface 10a of the roof 10 (mounting operation).

[0045] Next, the configuration regarding the mounting of the wind deflector arm 27, the preload element 28, and the wind deflector base 29 will be described in detail. First, the configuration of the wind deflector base 29 will be described.

[0046] As in Fig. 6 and Fig. 7, which form a cross-sectional structure Fig. As shown in Figure 6, the wind deflector base 29 has a box-shaped base body 31 with a long side and a short side and is provided with the bearing section 30. The base body 31 has a bottom section 32 extending along the longitudinal direction of the base body 31, a pair of side walls 33 rising from the bottom section 32, and a main body section 34 connecting the side walls 33 at an end section on one side of the bearing section 30 in such a way as to define the bearing section 30 in the longitudinal direction.

[0047] A plurality of (five in the present embodiment) claw sections 35, which fasten the main base body 31, i.e., the wind deflector base 29, to the guide rail 14 by locking it to the guide rail 14, are provided in the base section 32. Each claw section 35 projects from the side opposite the side where each side wall 33 rises with respect to the base section 32. In the bearing section 30, the base section 32 is provided with a base surface 32a on which a pair of extension sections 28b (in Fig. 6 and Fig. 7 (indicated by two-point single-dash lines) of the prestressing element 28 are installed.

[0048] A first locking section 36 (hereinafter referred to as the "locking piece") is provided on the base surface 32a for locking the pair of extension sections 28b. The locking pieces 36 extend towards the interior of the bearing section 30 with respect to the base surface 32a. Additionally, the locking piece 36 is located approximately in the middle of the area in which the bearing section 30 extends and substantially midway between the side walls 33 in the center of the base surface 32a. The locking piece 36 is provided with a pair of engagement claws 36a that project towards the opposite side walls 33.

[0049] Additionally, a through-hole 37, which penetrates the base surface 32a in the thickness direction, is provided in the base surface 32a. The through-hole 37 is located adjacent to the main body section 34. A second locking section 38 (hereinafter referred to as the "locking recess"), which locks both tip ends 28a of the prestressing element 28, is provided in the main body section 34. The locking recess 38 opens towards the base section 32 and has a depth in the direction in which each side wall 33 rises. The locking recess 38 is located on a side opposite the side of the bearing section 30 in the center of the main body section 34. The locking recess 38 communicates with the bearing section 30 through a through-hole 37 provided in the base surface 32a.

[0050] As seen through the two-point single-dash lines in the Fig. 6 and Fig. As shown in Figure 7, the pretensioning element 28 is mounted in the wind deflector base 29 in a state in which both pointed ends 28a are inserted into and locked in the locking recesses 38 and also extend through the through holes 37 to the bearing section 30, and the pair of extension sections 28b are hooked and locked by the pair of engagement claws 36a of the locking part 36. In other words, both the pointed ends 28a of the pretensioning element 28 and a pair of extension sections 28b are each individually locked in the pretensioning element 28. In this case, the locking pieces 36 are arranged between the lines of the pair of extension sections 28b.

[0051] In the bearing section 30, each side wall 33 is provided with a pair of pivot sections 39 into which the pivot section 40 of the wind deflector arm 27 is inserted. The pair of pivot sections 39 extends in a column-like shape from opposing inner wall surfaces 33a of the side walls 33 towards the opposite inner wall surface 33a. The pointed ends 39a of the pair of pivot sections 39 are positioned opposite each other, with a gap between them. The pivot section 39 is located on the side of the main body section 34 of the inner wall surface 33a.

[0052] With respect to the axle journal section 39, the cross-sectional shape in the foregoing direction is oval, with a pair of opposing linear sections 39b and a pair of opposing circular arc sections 39c, thus connecting the ends of the linear sections 39b. In the present embodiment, the oval cross-sectional shape has two symmetrical axes (not shown) that are perpendicular to each other. The pair of linear sections 39b extends in the direction in which each side wall 33 rises. In other words, the pair of circular arc sections 39c are oriented opposite each other in the direction in which each side wall 33 rises. A projection section 39d is provided individually on the surface of the pair of circular arc sections 39c, projecting outwards in the radial direction with respect to its position on the diagonal.The projecting section 39d is designed to extend along the same direction as the axle journal section 39. With respect to the surface of the projecting section 39d, the cross-sectional shape in the direction in which the axle journal section 39 projects has a circular arc with a curvature that is specified to be large compared to other parts.

[0053] As seen through the two-point single-dash lines in the Fig. 6 and Fig. As shown in Figure 7, the pivot section 40 is inserted into the axle pin section 39 between the opposite side walls 33 in the wind deflector base 29, so that the wind deflector arm 27 is mounted.

[0054] This section describes the configuration of the wind deflector arm 27. As in Fig. As shown in Figure 4, the pivot section 40 of the wind deflector arm 27 is provided with a pivot hole 41 for insertion into the pair of pivot sections 39. The pivot hole 41 has openings 42 on both sides of the wind deflector arm 27 in the lateral direction and has a depth in the lateral direction. The pivot hole 41 is tubular and surrounded by a circumferential wall 43, which has an inner circumferential surface 43a that is lubricated by a sliding surface 39e, which is the surface of a pair of circular arc segments 39c of the pivot section 39, and is subdivided into a pair of pivot holes 41a and 41b in the lateral direction of the wind deflector arm 27 by the bottom wall 44, which blocks the openings 42 from passing between them.

[0055] The circumferential wall 43 is provided with an insertion opening 45 through which the pair of linear sections 39b of the axle journal section 39 passes when the axle journal hole 41 is inserted into the axle journal section 39. The insertion opening 45 is provided for each pair of axle journal holes 41a and 41b. The insertion opening 45 penetrates the circumferential wall 43 in a radial direction to penetrate the inner circumferential surface 43a and the outer circumferential surface 43b of the circumferential wall 43. The insertion opening 45 is located on the side of the circumferential wall 43 opposite the side on which the wind deflector arm 27 extends. An opening length D2, which is the size of the opening through which the pair of linear sections 39b of the axle journal section 39 passes at the insertion opening 45, is set to be slightly larger than an intermediate surface length D1 (shown in Fig. 7) to be a quantity between the surfaces of the pair of linear sections 39b of the axle journal section 39.

[0056] In the present embodiment, the side of the circumferential wall 43 opposite the side on which the wind deflector arm 27 extends is a portion that does not slide with the sliding surface 39e of the axle journal section 39 when the wind deflector arm 27 moves up and down. In other words, each insertion opening 45 is provided within a region that does not slide with the sliding surface 39e of the axle journal section 39 when the wind deflector arm 27 moves up and down. In contrast to the insertion opening 45, the inner circumferential surface 43a of the circumferential wall 43 is designed to slide with the sliding surface 39e of the axle journal section 39. In this case, the inner circumferential surface 43a has at least one area for sliding with the sliding surface 39e of the axle journal section 39 when the wind deflector arm 27 moves up and down, and is provided in an area that is larger than the area disclosed previously.

[0057] Additionally, a thin section 46 is provided on a portion of the outer circumferential surface 43b of the circumferential wall 43, positioned opposite the pair of extension sections 28b of the prestressing element 28 in such a way as to prevent contact with the pair of extension sections 28b. The thin section 46 extends along the outer circumferential surface 43b on the side where the prestressing element 28 is mounted circumferentially from both ends of the circumferential wall 43 of the insertion opening 45 towards the side on which the wind deflector arm 27 extends. The thin section 46 is provided in a region that is greater than the rotational force when the wind deflector arm 27 moves up and down.

[0058] As in Fig. 5 and Fig. Figure 8, which depicts the end-surface structure, shows the pivot section 40 in a state where the wind deflector arm 27 is mounted with the wind deflector base 29, configured to bear against the sliding surface 39e, which is provided by the projecting section 39d of the axle journal section 39 over the inner circumferential surface 43a of the axle journal hole 41. In this case, the wind deflector arm 27 is configured to partially enclose a space for mounting with the pair of extension sections 28b of the preload element 28 in the thin section 46 of the pivot section 40.

[0059] Additionally, as in Fig. 5 and Fig. As shown in Figure 9, which depicts the end-surface structure, the wind deflector arm 27 is provided with an installation recess 60 in which the prestressing element 28 is installed. The installation recess 60 opens towards the prestressing element 28, which is mounted on the wind deflector base 29, and has a depth in a direction opposite to the prestressing element 28. A recess bottom 61, which is the bottom of the installation recess 60 and is an end face opposite the prestressing element 28 mounted on the wind deflector base 29, is provided with a pair of mounting sections 62 that project towards the opening side with respect to the recess bottom 61. The pair of mounting sections 62 are designed to extend parallel to each other along the direction in which the recess bottom 61 extends.The system section 62 has a low section 62a and a high section 62b, which have different projection amounts. The projection amount of the high section 62b is set to be large compared to that of the low section 62a. In the present embodiment, the system section 62 is a reinforcing section, that is, a so-called rib for increasing the stiffness of the wind deflector arm 27.

[0060] In a state where the wind deflector arm 27 is mounted on the wind deflector base 29, the bending section 28c of the pretensioning element 28 rests against the low section 62a of the pair of installation sections 62 in a state where they are in point contact with each other in the installation recess 60. In other words, when the wind deflector device 20 performs the deployment or storage operation in a state where the bending section 28c of the pretensioning element 28 comes into point contact with the low section 62a of the pair of installation sections 62 in the installation recess 60, its bending sections 28c each slide between a region Ra1 of the installation section 62. In the present embodiment, the low section 62a is an adjacent part of the installation section 62.

[0061] In the system section 62, the low section 62a, which extends along the direction of extension of the recess base 61, has the region Ra1 in which the bending section 28c of the prestressing element 28 slides when the wind deflector arm 27 moves up and down, and is provided in a region Ra2 that is larger than the region Ra1. In contrast, in system section 62, the high section 62b is provided in a region that extends along the direction of extension of the recess base 61 outside of the low section 62a. In this case, the high section 62b is provided in a region in which the bending section 28c of the prestressing element 28 does not slide when the wind deflector arm 27 moves up and down. In the present embodiment, the high section 62b is a non-adherent part of system section 62.

[0062] The following describes a method for mounting the wind deflector device 20. This mounting method comprises two main processes: a first process of mounting the preload element 28 to the wind deflector base 29, and a second process of mounting the wind deflector arm 27 to the wind deflector base 29.

[0063] As in Fig. As shown in Figure 10A, in the first process the prestressing element 28 is inserted from both tip ends 28a into the bearing section 30 of the wind deflector base 29. Here, the prestressing element 28 can be inserted from the bending section 28c through the through hole 37 into the bearing section 30 of the wind deflector base 29.

[0064] In particular, as in Fig. 10B shown, both tip ends 28a arranged in the through hole 37 provided in the bottom surface 32a of the bottom section 32 in the bearing section 30, and the prestressing element 28 is inserted such that the pair of extension sections 28b is in a state in which it extends in a direction in which each side wall 33 rises.

[0065] In the first process, the preload element 28 is then rotated so that both tip ends 28a, which pass through the through-hole 37, are inserted into the locking recess 38 of the main body section 34 and locked. In this case, the pair of extension sections 28b in the bearing section 30 is in a state in which the locking parts 36 are arranged between the lines.

[0066] Additionally, in the first process, the pretensioning element 28 is further rotated so that the pair of extension sections 28b, which insert the locking parts 36 between the lines, are hooked and locked onto the pair of engagement claws 36a of the locking parts 36. This secures the pretensioning element 28 to the wind deflector base 29, and the assembly of the pretensioning element 28 on the wind deflector base 29 is complete.

[0067] Then, as in Fig. As shown in Figure 10C, in the second process, the wind deflector arm 27 with the pivot section 40 is inserted into the bearing section 30 of the wind deflector base 29. Specifically, in the bearing section 30, the insertion opening 45 of the pivot hole 41 (41a and 41b) of the pivot section 40 is arranged to be opposite the pivot section 39 in the direction in which the pair of linear sections 39b extend, and the wind deflector arm 27 is inserted such that the pivot section 39 passes through the insertion opening 45. In this case, in the pivot section 40, the pivot hole 41 is inserted into the pivot section 39 successively from one side of the pair of circular arc sections 39c.

[0068] After the axle journal hole 41 is inserted into the axle journal section 39, the wind deflector arm 27 is rotated (moved downwards) over the axle journal section 39 in the second process. Accordingly, in the installation recess 60 of the wind deflector arm 27, the low section 62a of the pair of installation sections 62 rests against the bending section 28c of the already mounted pretensioning element 28, and the assembly of the wind deflector arm 27 on the wind deflector base 29 is complete. Additionally, the assembly of the wind deflector device 20 is completed by a process of mounting the wind deflector arm 27 to the wind deflector main body 26 and a process of attaching the wind deflector base 29 to the guide rail 14.

[0069] The operation and effects of the present exemplary embodiments are described below.

[0070] (1) As in Fig. As shown in Figure 5, part of the pretensioning element 28, which rests against the wind deflector arm 27, is a bent section 28c located within the U-shaped bent wire material. In other words, when the wind deflector arm 27 moves up and down, the pretensioning element 28 slides along the wind deflector arm 27 in a point contact state at the bent section 28c. Since the wire material is used as the preload element 28 in the present embodiment, even if the pair of extension sections 28b comes into contact with the wind deflector arm 27, the pair of extension sections 28b does not come into surface contact with the wind deflector arm 27, but does come into line contact with the wind deflector arm 27. In this case, for example, the sliding area between the preload element 28 and the wind deflector arm 27 can be reduced compared to a case in which a leaf spring is used as the preload element 28.Therefore, the sliding resistance can be reduced when the wind deflector arm 27 moves up and down, and the sliding noise based on the rotation of the wind deflector arm 27 can be reduced.

[0071] Furthermore, in the present embodiment, where a wire material is used as the prestressing element 28, even if there is an exposed part in an installed state of the prestressing element 28, a sharp corner or the like is not exposed. In this case, it is effective in improving user safety.

[0072] Additionally, as in Fig. As shown in Figure 6, in this embodiment where a wire material is used as the preloading element 28, a space can be provided between the lines of the pair of extension sections 28b of the preloading element 28. The locking elements 36 are arranged in this space as the structure for mounting the preloading element 28 to the wind deflector base 29. If, for example, a hole is formed in the leaf spring to provide this space when a leaf spring is used as the preloading element 28, the width must be increased to ensure the strength of the leaf spring. However, this increase in width is not necessary in this embodiment. Therefore, in the present embodiment, the wind deflector base 29 and the wind deflector device 20 itself can be miniaturized compared to a case where a leaf spring is used as the preloading element 28.

[0073] (2) As in Fig. 5 and Fig. As shown in Figure 9, the portion of the wind deflector arm 27 that abuts the bending section 28c of the prestressing element 28 is limited by the surfaces of the pair of mounting sections 62 of the wind deflector arm 27. This allows the reduced sliding area between the prestressing element 28 and the wind deflector arm 27 to be maintained appropriately. Therefore, it is possible to appropriately reduce the sliding resistance when the wind deflector arm 27 rotates.

[0074] (3) For example, at the recessed base 61 of the wind deflector arm 27, it is sufficient that at least the installation section 62 is provided on a part which bears against the prestressing element 28 when the wind deflector arm 27 moves up and down, and the effect in (2) can be achieved even if the installation section 62 is not provided on a part which does not bear against the prestressing element 28.

[0075] In contrast, in the present embodiment, the system section 62 is also provided on the part that does not bear against the prestressing element 28 when the wind deflector arm 27 moves up and down, and with respect to the high section 62b of the system section 62, a corresponding function as a reinforcing section, so-called rib, has been added. Accordingly, the stiffness of the wind deflector arm 27 can be increased.

[0076] (4) As in Fig. As shown in Figure 10C, when the wind deflector device 20 is mounted, the wind deflector arm 27 can be mounted on the wind deflector base 29 by passing the pair of linear sections 39b of the axle journal section 39 through the insertion opening 45 of the axle journal hole 41. Thus, when the axle journal hole 41 is inserted into the axle journal section 39, deformation of the pair of circular arc sections 39c of the axle journal section 39 and the insertion opening 45 of the axle journal hole 41 can be prevented. In addition, since the insertion opening 45 of the axle pin hole 41 is provided in an area that does not slide with the sliding surface 39e of the axle pin section 39 when the wind deflector arm 27 rotates in the middle of the inner circumferential surface 43a, even if the wind deflector arm 27 rotates, a falling off of the wind deflector arm 27 from the wind deflector base 29 can be prevented.

[0077] Additionally, as in Fig. As shown in Figure 5, the stiffness of the rotating section 40 in the axle journal hole 41 of the present embodiment is increased by providing the bottom wall 44, compared to a case where the bottom wall 44 is not provided. Even if the wind deflector arm 27 repeatedly moves up and down, this prevents the insertion opening 45 of the axle journal hole 41 (distance D2 in the present embodiment), i.e., the so-called entry opening, from widening, and a condition preventing the wind deflector arm 27 from falling off the wind deflector base 29 can be appropriately maintained. Therefore, the service life of the wind deflector device 20 can be increased, and its reliability can be improved.

[0078] (5) As in Fig. As shown in Figure 8, in the present embodiment, the mounting space of the rotating section 40 and the preloading element 28 can be wrapped together by the amount corresponding to the provision of the thin section 46 in the rotating section 40. Accordingly, the mounting space of the rotating section 40 and the preloading element 28 can be reduced. In this case, it is effective to miniaturize the wind deflector base 29 and the wind deflector device 20 itself.

[0079] (6) As in Fig.As shown in Figure 8, in a state where the wind deflector arm 27 is mounted on the wind deflector base 29, the inner circumferential surface 43a of the rotating section 40 and the sliding surface 39e of the pivot section 39 are in contact via a projecting section 39d provided on the sliding surface 39e. In other words, a gap resulting from the manufacturing and dimensional tolerances of the element can be eliminated between the inner circumferential surface 43a of the rotating section 40 and the pair of circular arc sections 39c of the pivot section 39. Consequently, when the wind deflector arm 27 moves up and down, the generation of rattling can be prevented, and smooth movement can be achieved.

[0080] (7) In the present embodiment, when the wind deflector device 20 is mounted, the pretensioning element 28 can be mounted on the wind deflector base 29 by means of the locking part 36 and the locking recess 38. Since it is possible in this case to lock both pointed ends 28a of the pretensioning element 28 and to lock the pair of extension sections 28b separately, irrespective of the wind deflector arm 27, the pretensioning element 28 can be attached to the wind deflector base 29 on its own. As described above, the function of attaching the pretensioning element 28 to the wind deflector base 29 on its own can be added to the function of the wind deflector base 29 by means of the locking part 36, which forms the wind deflector base 29 and the locking recess 38. Therefore, it is not necessary to provide other components for fastening the prestressing element 28, and the number of components can be reduced.In other words, the wind deflector device 20 itself can be miniaturized.

[0081] Additionally, in a state where the preload element 28 is mounted on the wind deflector base 29, the wind deflector arm 27 can be mounted continuously with the wind deflector base 29 without having to worry about a positional deviation of the preload element 28. In this case, it is effective in improving the feasibility of mounting the wind deflector device 20.

[0082] The previously described embodiment can also be implemented in the following aspects, which have been modified appropriately.

[0083] The wind deflector base 29 can be configured to fasten the prestressing element 28, and the fastening method can be modified accordingly. For example, both pointed ends 28a of the prestressing element 28 can be locked with the same structure as the locking parts 36. Furthermore, the pair of engagement claws 36a can be designed to project towards the inner wall surface 33a opposite the inner wall surface 33a of each side wall 33.

[0084] Additionally, in a case where the fastening of the pretensioning elements 28 is sufficiently ensured by locking both tip ends 28a, the locking pieces 36 may be omitted. The omission of the locking piece applies equally to the locking recess 38. Furthermore, in the embodiment described above, instead of fastening the pretensioning element 28 solely to the wind deflector base 29, the pretensioning element 28 may be fastened to the wind deflector base 29 in relation to the wind deflector arm 27.

[0085] In the previously described embodiment, the projecting section 39d can be designed to project radially inwards from the inner circumferential surface 43a of the axle journal bore 41, instead of being located on the axle journal section 39. In a case where the manufacturing tolerance and the dimensional tolerance of the element are small, the projecting section 39d may be omitted.

[0086] The projecting section 39d can eliminate the gap, based on the manufacturing and dimensional tolerances of the element, between the inner circumferential surface 43a of the rotary section 40 and the pair of circular arc sections 39c of the axle journal section 39. This can be achieved, for example, by providing the projecting section intermittently along the direction in which the axle journal section 39 extends, or only in a portion of the direction in which the axle journal section 39 extends. Additionally, the surface of the projecting section 39d can have a cross-sectional shape, such as a cone or a projection.

[0087] In a state in which the wind deflector arm 27 is mounted on the wind deflector base 29, in a configuration in which the mounting space of the pivot section 40 and the pair of extension sections 28b of the preloading element 28 do not overlap, the thin section 46 may not be preferably provided to reinforce the pivot section 40, i.e. the wind deflector base 29.

[0088] In the axle journal section 39, a pair of curved sections can be provided as a cross-sectional shape instead of the pair of linear sections 39b. The curved section can have a small curvature, similar to that of the pair of circular arc sections 39c. In this case, it is sufficient in the insertion opening 45 if the opening length D2 is slightly larger than the maximum size between the surfaces of the pair of curved sections of the axle journal section 39.

[0089] The axle journal section 39 can have a circular cross-sectional shape. If, in this case, the wind deflector arm 27 is mounted on the wind deflector base 29, the insertion opening 45 can be elastically deformed so that the axle journal hole 41 can be inserted into the axle journal section 39.

[0090] The bottom wall 44 may not be provided in the axle journal hole 41, and a through-hole may be open to allow passage between the openings 42. In this case, the axle journal section 39 may be an axle journal that extends to connect between opposing side walls 33.

[0091] The axle pin hole 41 can be configured to be inserted into the axle pin section 39 from the width direction of the wind deflector arm 27 without providing the insertion opening 45.

[0092] In the installation recess 60, the area in which the low section 62a and the high section 62b are provided can be modified appropriately according to the stiffness of the wind deflector arm 27. For example, the overall projection of the installation section 62 can be the same. Additionally, the installation section 62 can be one rib or three or more ribs extending along the direction in which the recess floor 61 extends, or a grid-like rib extending also in the width direction of the installation recess 60. Furthermore, in the installation recess 60, it is sufficient if at least the installation section 62 (low section 62a) is provided in the area Ra1 in which the bending section 28c of the prestressing element 28 slides when the wind deflector arm 27 moves up and down.Additionally, in the installation recess 60, in a case where the stiffness of the wind deflector arm 27 is sufficiently ensured, the system section 62 may not be provided.

[0093] The wind deflector unit 50 can be one that does not have a mesh if it can prevent air vibrations caused by the intake of wind into a passenger compartment, but which has a slot instead of a mesh or can be made of metal.

[0094] The wind deflector device 20 can be configured to omit the lower frame 21. In this case, the connection section 50a of the wind deflector unit 50 can be attached to the lower side (for example, the front housing 15) of the upper surface 10a of the roof 10.

[0095] The wind deflector frame 25 may include at least the wind deflector arm 27 and may not include the wind deflector main body 26. In this case, the connecting section 50b of the wind deflector unit 50 may be attached to the tips of the pair of wind deflector arms 27.

[0096] Each of the modification examples can be applied in combination with each other, for example the configuration that does not have the lower frame 21 and the wind deflector main body 26, and the configuration of the other modification examples can be applied in combination with each other.

[0097] The principles, preferred embodiment, and mode of operation of the present invention have been described in the preceding description. However, the invention to be protected is not to be interpreted as being limited to the specific disclosed embodiments. Furthermore, the embodiments described herein are to be considered illustrative and not limiting. Variations and modifications may be made by others, and equivalents may be used, without departing from the purpose of the present invention. Accordingly, it is expressly intended that all such variations, modifications, and equivalents falling within the scope of protection of the present invention, as defined in the claims, are included therein.
