JP 2003-118381 A

  By the way, according to Patent Document 1, as shown in FIG. 7, when the movable panel 90 is in the fully closed state, the rear edge 91 is taken over substantially the entire length of the vehicle in the width direction (direction orthogonal to the paper in FIG. 7). The attached sealing member 92 is in pressure contact with the rear edge 97 of the opening 96 formed in the roof 95. For this reason, when the movable panel 90 is tilted (in this case, tilt down) from the fully closed state, the friction between the seal member 92 and the rear edge 97 causes the roof 95 to be elastically deformed so as to be dragged. Then, when the seal member 92 and the rear edge 97 are released by the further tilt operation of the movable panel 90, a repelling noise (noise) may be generated along with the elastic return of the roof 95. Alternatively, a rattling noise (noise) may be generated as the tilt operation of the movable panel 90 released from the roof 95 progresses rapidly.

  An object of the present invention is to provide a sunroof device capable of suppressing the generation of abnormal noise when the movable panel tilts from the fully closed state.

  The sunroof device which solves the above-mentioned subject is a pair of guide rails provided so that it may extend in the direction of a cross of the width direction edge of a vehicle of the opening formed in the roof of vehicles, and both guide rails A vehicle comprising: a pair of slide members slidably supported; and a movable panel having a front end portion rotatably connected to the two guide rails and engaged with the two slide members to open and close the opening. It is attached to a pair of support brackets for supporting both widthwise edges, and a first rear edge which is a rear edge of either the opening or the movable panel, and the other one of the other in the fully closed state of the movable panel And a seal member in pressure contact with the second rear edge, which is the rear edge, and the two support members move with the front end portion as a fulcrum by the two slide members moving in the longitudinal direction of the vehicle with respect to the two support brackets. Rotate to move up and down Serial and the movable panel is configured to tilt operation, the tilt operation from the fully closed state of the movable panel is set to proceed asymmetrically in the width direction of the vehicle.

  According to this configuration, the tilt operation from the fully closed state of the movable panel proceeds asymmetrically in the width direction of the vehicle. Therefore, even when the movable panel is elastically deformed so as to be dragged by the frictional force between the seal member and the second rear edge when the movable panel is tilted from the fully closed state, the seal member and the second rear are The edge does not come off simultaneously over substantially the entire length of the vehicle in the width direction. For this reason, repulsion noise may be generated with elastic return of the roof, or striking noise may be generated due to rattling accompanying rapid progress of the tilt operation of the movable panel released from the roof. It can be suppressed.

  In the above-mentioned sunroof device, in the transition in which the movable panel tilts from the fully closed state, rotations at least one of raising and lowering with the front end portions of the support brackets as fulcrums are set to have different timings. Is preferred.

  According to this configuration, in the transition in which the movable panel tilts from the fully closed state, the pivoting at least one of raising and lowering with the front end portions of the two support brackets as fulcrums becomes different timings from each other. The tilt operation from the fully closed state of the movable panel proceeds asymmetrically in the width direction of the vehicle. Therefore, for example, the movable panel is tilted as compared to the case where the movable panel is shifted in the front-rear direction on both sides in the width direction of the vehicle to advance the tilt operation from the fully closed state of the movable panel asymmetrically in the width direction of the vehicle. Operation can be stabilized more.

  In the above-mentioned sunroof device, a first engaging portion which is either one of an engaging convex portion formed on each of the two sliding members and an engaging concave portion in which the engaging convex portion is engaged, and the both supporting brackets A second engaging portion which is the other of the engaging convex portion and the engaging concave portion formed on each of the plurality of engaging recesses, and at least one of raising and lowering with the front end portions of the two support brackets as a fulcrum The movement is made to make the displacements of the two second engagement parts guided by the two first engagement parts different from each other in accordance with the longitudinal movement of the two slide members with respect to the two support brackets. Preferably, the timings are set to be different from each other.

  According to this configuration, the front end portions of both the support brackets are made by the extremely simple engagement structure by the two first engagement parts and the two second engagement parts (both engagement convex parts and both engagement concave parts). It is possible to set the pivots that perform at least one of raising and lowering on the fulcrum so as to be at different timings.

  The present invention has the effect of being able to suppress the generation of abnormal noise when the movable panel tilts from the fully closed state.

  Hereinafter, one embodiment of a sunroof device will be described. Hereinafter, the longitudinal direction of the vehicle will be referred to as "longitudinal direction", and the upper side and lower side of the vehicle in the height direction will be referred to as "upper side" and "lower side", respectively. Further, the inside in the width direction of the vehicle heading toward the inside of the vehicle is referred to as "the inside of the vehicle", and the outside in the width direction of the vehicle facing toward the outside of the vehicle is referred to as the "outside of the vehicle".

  As shown in FIG. 1, while the substantially square shaped opening 10a is formed in the roof 10 of vehicles, such as a motor vehicle, the sunroof apparatus 11 is mounted. The sunroof device 11 includes a substantially rectangular movable panel 12 made of, for example, a glass plate, which moves in the front-rear direction to open and close the opening 10a.

  The movable panel 12 has a tilt-up operation in which the rear portion moves upward by rotating in one direction around its front portion, and a tilt-down operation in which the rear portion moves downward by rotating in the other direction around the front portion, And it is attached so that slide operation in the direction of order is possible. In the opening and closing operation of the movable panel 12, a so-called inner sliding type in which the sliding operation is performed in the tilt down state is adopted.

  As shown in FIG. 2, a pair of guide rails 13 is provided to extend in the front-rear direction at both side edges of the opening 10 a in the vehicle width direction. Each guide rail 13 is made of, for example, an extruded material of aluminum alloy, and has a constant cross section in the longitudinal direction. A rear shoe 21 as a pair of sliding members is slidably guided and supported by the two guide rails 13 in the front-rear direction.

  Further, on both guide rails 13, front end portions 23 of a pair of substantially elongated support brackets 22 which extend in the front-rear direction and support both widthwise edges of the movable panel 12 in the width direction are supported. The front end portion 23 of each support bracket 22 is supported by the guide rail 13 so as to be rotatable about an axis extending in the width direction of the vehicle ahead of the rear shoe 21 and in the width direction of the vehicle. Each support bracket 22 is engaged with and supported by the rear shoe 21. Both rear shoes 21 tilt up, tilt down or slide the movable panel 12 supported by the support brackets 22 in accordance with the movement in the front-rear direction.

  Further, an electric motor 16 having an output gear, for example, is installed in front of the vehicle of both guide rails 13. The electric motor 16 is connected to each rear shoe 21 via a pair of belt-like belts 17, and simultaneously moves the two rear shoes 21 in the front-rear direction along the guide rails 13.

  As shown in FIG. 3, each rear shoe 21 is configured to include a resin-made shoe portion 31 attached to the guide rail 13 slidably in the front-rear direction, and a main body portion 32 made of a metal plate. The main body portion 32 has a support wall 32a which rises upward inside the support bracket 22 at the vehicle inner side, and is connected to the upper end of the support wall 32a and has a substantially corrugated plate-like engagement piece 32b which protrudes outward. It further has a substantially bottomed cylindrical engagement pin 32c which protrudes from the support wall 32a to the outside of the vehicle below the engagement piece 32b. The main body portion 32 forms an engagement recess 33 as a first engagement portion which is relatively recessed inward in the vehicle between the engagement piece 32b and the engagement pin 32c.

  On the other hand, the support bracket 22 is supported by the guide rail 13 so as to be rotatable about an axis extending in the width direction of the vehicle and slidably in the front and rear direction by the front shoe 24 provided at the front end portion 23 . Further, the support bracket 22 has a substantially flange-like engagement convex portion 25 as a second engagement portion that protrudes rearward from the lower end toward the vehicle inner side more rearward than the front shoe 24 than the vehicle. In the support bracket 22, the engagement convex portion 25 is engaged between the engagement piece 32 b and the engagement pin 32 c provided on the rear shoe 21 (the main body portion 32) (the engagement concave portion 33), whereby the support bracket 22 is vertically moved. Is restricted, and is engaged with the rear shoe 21 so that relative movement along the longitudinal direction (generally in the front-rear direction) of the engagement convex portion 25 is permitted.

  As shown by a solid line in FIG. 4, the engagement projection 25 is connected to a flat portion 25a extending substantially horizontally in the front-rear direction when the movable panel 12 is in the fully closed state, and the front end of the flat portion 25a. And a rear inclined portion 25c connected to the rear end of the flat portion 25a and extending obliquely rearward and upward of the vehicle. Then, at the rear end of the rear side inclined portion 25c, there is connected a regulating portion 25d which is folded back below the rear side inclined portion 25c. When the movable panel 12 is in the fully closed state, the rear shoe 21 (the engagement piece 32b or the like) is disposed at the flat portion 25a in the front-rear direction.

  Therefore, as shown by a broken line in FIG. 4, when the rear shoe 21 moves along the guide rail 13 to the front of the vehicle and enters the front inclined portion 25 b in the fully closed state of the movable panel 12, the support bracket 22 By being pushed up to the engaging pin 32 c at the engaging convex portion 25, the engaging convex portion 25 pivots around the front end 23 in the counterclockwise direction in the drawing. At this time, the movable panel 12 performs a tilt up operation (tilt operation) in which the rear portion is moved upward with respect to the front portion. Then, when the rear shoe 21 reaches the end (front end) of the front side inclined portion 25b, the movable panel 12 stops the tilt-up operation and is in the tilt-up state.

  On the contrary, as shown by a two-dot chain line in FIG. 4, when the rear shoe 21 moves to the rear of the vehicle along the guide rail 13 and enters the rear side inclined portion 25 c in the fully closed state of the movable panel 12, The bracket 22 is pivoted in the clockwise direction in the drawing about the front end 23 by being pushed down to the engagement piece 32 b at the engagement convex portion 25. At this time, the movable panel 12 performs a tilt down operation (tilt operation) in which the rear portion is moved downward with respect to the front portion. Then, when the rear shoe 21 reaches the end (rear end) of the rear side inclined portion 25c, the restricting portion 25d restricts the rearward movement of the vehicle with respect to the engagement convex portion 25 (support bracket 22). At this time, the movable panel 12 ends the tilt down operation and enters the tilt down state.

  Then, when the rear shoe 21 further moves to the rear of the vehicle along the guide rail 13, the support bracket 22 integrally moves to the rear of the vehicle, and the movable panel 12 is opened with the tilt down state. Thereby, the movable panel 12 is fully opened, and the opening 10 a is opened.

  At the rear edge 12a of the movable panel 12 as the first rear edge, a seal member 40 made of an extruded material such as synthetic rubber such as EPDM or thermoplastic elastomer is provided over substantially the entire length of the vehicle in the width direction. It is attached. On the other hand, the trailing edge 10b as the second trailing edge of the opening 10a has a flange shape that hangs downward. The seal member 40 presses the rear edge 10b against the rear edge 10b when the movable panel 12 is in the fully closed state, thereby suppressing water immersion in the vehicle compartment. The sealing member 40 is in contact with the rear edge 10b at a predetermined pressure or more in order to satisfy the waterproof performance in the required specification.

  As shown in FIG. 5, the rear side inclined portion 25c of the engagement convex portion 25 formed on one support bracket 22 disposed on the right side toward the front of the vehicle (hereinafter also referred to as "rear side inclined portion 25cR" Is formed into a substantially arc shape, and when the movable panel 12 is in a fully closed state, it is convex toward the rear and downward of the vehicle. Similarly, as shown by a two-dot chain line in FIG. 5, a rear inclined portion 25 c of the engagement convex portion 25 formed on the other support bracket 22 disposed on the left side toward the front of the vehicle (hereinafter referred to as “ The rear inclined portion 25cL ′ ′) is also formed in a substantially arc shape, and when the movable panel 12 is in a fully closed state, it is convex toward the rear lower side of the vehicle.

  However, the rear side inclined portions 25cR and 25cL are formed asymmetrically in the width direction of the vehicle. Specifically, the radius of curvature of the rear inclined portion 25cL is set smaller than the radius of curvature of the rear inclined portion 25cR. Thereby, the rising from the flat portion 25a of the rear side inclined portion 25cL is slower at a position closer to the flat portion 25a and steeper at a position away from the flat portion 25a than that of the rear side inclined portion 25cR. It has become. Accordingly, when both rear shoes 21 move to the rear of the vehicle along both guide rails 13, the rear inclined portion 25cR is pushed down more rapidly than the rear inclined portion 25cL by the engagement pieces 32b in the first half, The rear inclined portion 25cL is pushed down more rapidly than the rear inclined portion 25cR by the joint piece 32b. Then, when both rear shoes 21 reach the end of both rear side inclined portions 25cR, 25cL, the push-down of both rear side inclined portions 25cR, 25cL by both engagement pieces 32b is completed. Thus, the tilt down operation from the fully closed state of the movable panel 12 proceeds asymmetrically in the width direction of the vehicle.

  As described above, as shown in FIG. 6, the seal member 40 in pressure contact with the rear edge 10b in the fully closed state of the movable panel 12 has one side (right side) in the width direction of the vehicle. The other side (left side) descends and falls out of the trailing edge 10b, and the other side (left side) falls behind and falls off the trailing edge 10b in advance. As described above, the seal member 40 is inclined from the rear edge 10b in the width direction of the vehicle and the contact area with the rear edge 10b is gradually reduced.

The operation and effects of the present embodiment will be described.
(1) In the present embodiment, the tilt down operation from the fully closed state of the movable panel 12 proceeds asymmetrically in the width direction of the vehicle. Therefore, even if the roof 10 is elastically deformed so as to be dragged by the frictional force between the seal member 40 and the rear edge 10 b when the movable panel 12 is tilted down from the fully closed state, the seal member 40 and the rear edge 10 b It does not come off simultaneously over substantially the entire length in the width direction. For this reason, a repulsion noise is generated with elastic return of the roof 10, or a hammering noise is generated due to rattling with the rapid progress of the tilt-down operation of the movable panel 12 released from the roof 10 Can be suppressed.

  (2) In the present embodiment, in the transition of the movable panel 12 from the fully closed state to the tilt-down operation, the movable panel 12 has different timings of pivoting downward with the front end portions 23 of the support brackets 22 as a fulcrum. Tilt-down operation from the fully closed state of the vehicle travels asymmetrically in the width direction of the vehicle. Therefore, for example, the movable panel 12 is shifted in the longitudinal direction on both sides in the width direction of the vehicle, and the tilt down operation from the fully closed state of the movable panel 12 proceeds asymmetrically in the width direction of the vehicle. The tilt down operation can be stabilized more.

  (3) In the present embodiment, the downward movement of the support brackets 22 with the front end portion 23 as the fulcrum is guided to the both engagement recesses 33 as the rear shoes 21 move in the front-rear direction with respect to the support brackets 22. The displacements of the engagement projections 25 are set to be different from each other so as to be different from each other. As described above, due to the extremely simple engagement structure formed by the both engaging convex portions 25 and both engaging concave portions 33, it is possible to set the pivoting movement of the two supporting brackets 22 with the front end 23 as a fulcrum at different timings. .

  (4) In the present embodiment, when both rear shoes 21 (engagement recess 33) simultaneously reach the end of both rear inclined portions 25cR and 25cL, the opening operation of the movable panel 12 in the tilt down state is performed as the width of the vehicle. It can be performed in a symmetrical posture in the direction.

The present embodiment can be modified as follows. The present embodiment and the following modifications can be implemented in combination with one another as long as there is no technical contradiction.
In the embodiment, the seal member 40 is attached to the rear edge 10b as the first rear edge of the opening 10a and is pressed against the rear edge 12a as the second rear edge of the movable panel 12 Good.

  In the embodiment, the tilt-up operation from the fully closed state of the movable panel 12 may be set to proceed asymmetrically in the width direction of the vehicle. Specifically, the trajectories of the front side inclined portions 25b of the both engagement convex portions 25 may be made different from each other.

  In the above embodiment, the rear shoe 21 is provided with an engagement convex portion of a locus obtained by reversing the locus of the engagement convex portion 25 back and forth, and the support bracket 22 is formed with an engagement concave portion in which the engagement convex portion can be engaged. You may

  In the embodiment described above, the engagement between the rear shoe 21 and the support bracket 22 is an engagement recess formed in the support bracket 22 in the width direction of the vehicle, with the engagement convex portion protruding toward the vehicle outer side from the support wall 32a. It may be done by engaging in The engagement recess draws a locus according to the engagement protrusion 25.

  In the embodiment, for example, the movable panel 12 may be shifted in the front-rear direction on both sides in the width direction of the vehicle to advance the tilt operation from the fully closed state of the movable panel 12 asymmetrically in the width direction of the vehicle.

  In the embodiment, in the opening and closing operation of the opening 10 a by the movable panel 12, a so-called outer sliding type may be adopted in which the sliding operation is performed in the tilt up state.

The technical idea which can be grasped from the above-mentioned embodiment and modification is described.
(A) In the above-mentioned sunroof device,
The sunroof apparatus set so that the rotation which descend | falls with the front end part of both said support brackets as a fulcrum becomes a mutually different timing in transition in which the said movable panel tilts from a fully closed state.

(B) In the above-mentioned sunroof device,
By moving the two slide members to the rear of the vehicle with respect to the two support brackets, the movable panel in the fully closed state is configured to shift to the tilt down state and perform an opening operation.
The sunroof apparatus set so that the rotation which descend | falls with the front end part of both said support brackets as a fulcrum will be completed simultaneously in the transition which the said movable panel tilts from a fully closed state.

  According to this configuration, in the transition of the movable panel from the fully closed state to the tilt operation, the pivoting to lower the front ends of the support brackets as a fulcrum, that is, the transition to the tilt down state of the movable panel is simultaneously completed. Thus, the opening operation in the subsequent tilt down state can be performed in a symmetrical posture in the width direction of the vehicle.
