Description

Technical Field

[0001] The present invention relates to a vehicle side glass device.

Background Art

[0002] Generally, when a passenger gets into a vehicle while holding luggage, the passenger places the luggage in the passenger seat, rear seat, trunk, etc. of the vehicle.

[0003] When the rear door of the vehicle is not a sliding type, it may be difficult to open the door in a parking lot when other vehicles are parked adjacent to it. Also, there may be cases where the passenger cannot arrange to place the luggage in the rear seat. Therefore, for example, there is a demand that it would be convenient if the passenger's luggage such as hand luggage, shopping bags, umbrellas, coats, etc. could be placed inside the vehicle through an open window without opening the door.

[0004] As a technology corresponding to the above requirements, a slider slidably fitted to a main rail arranged at the upper and lower edges of a side window is attached to a window glass via a flip-out link, and a guide of the flip-out link is slidably fitted to a sub-rail arranged outside the main rail. The sub-rail is provided with a bent portion for flipping out the window glass, and the slider is slid by a motor via a wire, thereby further opening the window glass of the side window of a vehicle such as an automobile (see, for example, Patent Document 1).

In this embodiment, it will be described that an upper rail part 210 is provided at the upper end part of the side glass part 100 and a lower rail part 220 is provided at the lower end part of the side glass part 100. The upper rail part 210 and the lower rail part 220 are formed of a member such as metal or resin and form a substantially straight line in the vehicle longitudinal direction.

[0020] The upper rail portion 210 extends in the vehicle front-rear direction at the rear side of the vehicle of the upper end portion of the side glass portion 100, and is fixed to the vehicle body BD at the rear side of the vehicle in the vehicle V. As shown in FIG. 2(a), the upper rail portion 210 forms a C shape having an opening portion on the lower side of the vehicle when viewed from the front side of the vehicle. Inside the upper rail portion 210, a C-shaped groove for sliding the side glass portion 100 in the vehicle front-rear direction is formed.

[0021] The lower rail portion 220 extends in the vehicle front-rear direction at the rear side of the vehicle of the lower end portion of the side glass portion 100, and is fixed to the vehicle body BD. As shown in FIG. 2(b), the lower rail portion 220 has an opening portion on the outer side in the vehicle width direction when viewed from the front side of the vehicle. Inside the lower rail portion 220, an elliptical groove portion OG is formed.

[0022] The upper rail portion 210 and the lower rail portion 220 are provided with a taper such that the width in the vehicle vertical direction or the width in the vehicle width direction inside the upper rail portion 210 and the lower rail portion 220 gradually becomes narrower from the front side of the vehicle toward the rear side of the vehicle. Specifically, for example, the opening portion at the front side of the vehicle of the upper rail portion 210 is provided wide with the width in the vehicle width direction between the upper rail portion 210 and the side glass portion 100 as the width LW1. As going from the front side of the vehicle toward the rear side of the vehicle, the width in the vehicle width direction of the upper rail portion 210 gradually becomes narrower than the width LW1. The opening portion at the front side of the vehicle of the lower rail portion 220 is provided wide with the width in the vehicle vertical direction between the lower rail portion 220 and the adjustment mechanism portion 400 as the width LW2. As going from the front side of the vehicle toward the rear side of the vehicle, the width in the vehicle width direction of the lower rail portion 220 gradually becomes narrower than the width LW2.

[0023] (Regarding the side glass moving portion 300) The side glass moving part 300 is provided on the vehicle lower side of the side glass part 100 and slides the side glass part 100 in the vehicle longitudinal direction. The side glass moving part 300 is rotatably fitted to the side glass fitting part 130. As shown in FIG. 3, the side glass moving part 300 includes a pivot fitting part 310, a sliding part 320, a slider base part 330, and a slide shaft 340. As shown in FIG. 4(a), a sliding pedestal 350 is provided at the vehicle rear side part of the slider base part 330.

[0024] The pivot fitting part 310 has a substantially spherical shape formed of a member such as metal, hard resin, or glass. As shown in FIG. 3, a cylindrical bar PL is coupled to the vehicle lower side of the pivot fitting part 310, and the pivot fitting part 310 and the sliding part 320 are coupled via the cylindrical bar PL. The pivot fitting part 310 is rotatably fitted to a recess FH provided in the side glass fitting part 130.

[0025] The sliding part 320 is slidably fitted to the slider base part 330 and placed on the vehicle upper side of the slider base part 330. The sliding part 320 has a substantially rectangular parallelepiped shape formed of a member such as metal, hard resin, or glass. A cylindrical through-hole SH extending in the vehicle longitudinal direction is provided in the sliding part 320. A screw groove is formed inside the through-hole SH in the sliding part 320 and engages with the screw thread of the slide shaft 340 passing through the inside of the through-hole SH. An interval d1 is secured between the vehicle upper side of the sliding part 320 and the vehicle lower side of the side glass part 100. The interval d1 is set to a distance at which the side glass part 100 and the pivot fitting part 310 do not come into contact when the side glass part 100 rotates and moves in the vehicle vertical direction and vehicle width direction with the pivot fitting part 310 as the rotation axis.

[0026] The slider base portion 330 has a substantially U-shaped form with an opening on the upper side of the vehicle, made of a member such as metal or hard resin. The slider base portion 330 is fixed to the upper side of the vehicle of the rear seat door DR. On the upper side of the vehicle of the slider base portion 330, the sliding portion 320 is fitted and placed thereon, and slides in the longitudinal direction of the vehicle.

[0027] The slide shaft 340 is a cylindrical bar formed of a member such as metal or hard resin. A spiral thread is formed on the slide shaft 340. The slide shaft 340 penetrates through the inside of the through hole SH in the sliding portion 320. The thread provided on the slide shaft 340 engages with the thread groove provided in the through hole SH. For example, a drive portion DM for rotating the slide shaft 340 is provided at the front end of the vehicle of the slide shaft 340.

[0028] As shown in Fig. 4(a), the sliding pedestal 350 is provided on the rear side of the vehicle of the slider base portion 330. The sliding pedestal 350 has a substantially rectangular parallelepiped shape made of a member such as metal or hard resin, and is fixed inside the slider base portion 330. On both sides in the vehicle width direction of the sliding pedestal 350, ribs RT for correcting the position of the side glass portion 100 are provided. The side glass portion 100 is placed on the upper side of the vehicle of the sliding pedestal 350, and the side glass portion 100 slides on the upper side of the vehicle of the sliding pedestal 350. The sliding pedestal 350 may be integrally formed with the slider base portion 330.

[0029] (Regarding the adjustment mechanism portion 400) The adjustment mechanism portion 400 is provided on the rear side of the vehicle of the side glass portion 100, and guides and fits the side glass portion 100 to the slide rail portion 200 when opening and closing the side glass portion 100. As shown in Fig. 4(a) and Fig. 4(b), the adjustment mechanism portion 400 includes an adjustment mechanism fitting portion 410 fixed to the side glass portion 100 and a fixed bar 420.

[0030] The adjustment mechanism fitting portion 410 is provided on the side glass portion 100 so as to be angle-changeable in the vehicle vertical direction and the vehicle width direction. When the side glass portion 100 moves toward the rear side of the vehicle, the adjustment mechanism fitting portion 410 fits into the slide rail portion 200 and slides. The adjustment mechanism fitting portion 410 has an elliptical shape formed by a member such as metal or hard resin. The adjustment mechanism fitting portion 410 has a major axis LA in the longitudinal direction forming an axis facing the vehicle front-rear direction, and a minor axis SA in the short direction forming an axis facing the vehicle width direction, and is provided on the door glass frame 120 in the side glass portion 100. The major axis apex portion MV on the rear side of the vehicle in the adjustment mechanism fitting portion 410 is located on the rear side of the vehicle.

[0031] A through hole TH penetrating the adjustment mechanism fitting portion 410 in the vehicle width direction is provided at the longitudinal center portion and the vehicle vertical center portion of the adjustment mechanism fitting portion 410. The through hole TH faces the same direction as the minor axis SA. In the through hole TH, triangular pyramid-shaped recesses having vertices at the vehicle width center portion of the adjustment mechanism fitting portion 410 are formed symmetrically in the vehicle width direction. A fixing bar 420 penetrates through the through hole TH in the vehicle width direction.

[0032] The fixing bar 420 is a bar formed by a member such as metal or hard resin, and the fixing bar axis FA of the fixing bar 420 is provided facing the vehicle width direction. The fixing bar 420 has a diameter smaller than the inner diameter of the through hole TH inside the through hole TH. The fixing bar 420 penetrates through the through hole TH and the adjustment mechanism fitting portion 410 is provided so as to be operable. The outer end portion of the fixing bar 420 on the vehicle outside has a substantially cylindrical shape with a diameter larger than that of the through hole TH and is fixed to the door glass frame 120. The inner end portion of the fixing bar 420 on the vehicle inside has a disk shape with a diameter larger than that of the through hole TH.

[0033] <Function and Effect> In the vehicle side glass device 10 according to the present embodiment configured as described above, the case where the side glass part 100 is opened and closed will be described with reference to FIGS. 5 to 7.

[0034] (When opening the side glass part 100) When the user opens the side glass part 100, for example, an operation to open the side glass part 100 is performed by a remote control key or a switch provided in the vehicle V. At this time, the side glass part 100 is in the state shown in FIG. 5(a).

[0035] When an operation to open the side glass part 100 is performed by the user, the slide shaft 340 rotates by the drive part DM in the side glass moving part 300, and the sliding part 320 moves toward the rear side of the vehicle along the slider base part 330. Since the pivot fitting part 310 coupled to the sliding part 320 is fitted into the concave part FH provided in the side glass fitting part 130, the sliding part 320 slides the side glass part 100 toward the rear side of the vehicle.

[0036] When the side glass part 100 is pushed toward the rear side of the vehicle, the adjustment mechanism fitting part 410 provided on the rear side of the vehicle of the side glass part 100 slides toward the rear side of the vehicle. The long axis apex part MV on the rear side of the vehicle in the adjustment mechanism fitting part 410 having an elliptical shape moves toward the elliptical groove part OG opened in the lower end rail part 220 of the slide rail part 200. As shown in FIGS. 6(a) to 6(c), the long axis apex part MV is provided so as to be rotatable around the fixed bar 420 in the range of the triangular pyramid shape of the through hole TH in the directions indicated by the arrows AR1 to AR3. At this time, if a distortion occurs between the vehicle body BD and the rear seat door RD, a displacement occurs between the long-axis apex MV in the adjustment mechanism fitting portion 410 and the groove OG in the lower end rail portion 220. When the long-axis apex MV is within the range of the groove OG, the adjustment mechanism fitting portion 410 rotates and moves in the directions indicated by the arrows AR1 to AR3. Then, by fitting the long-axis apex MV with the groove OG, the adjustment mechanism fitting portion 410 is guided in the direction of fitting with the lower end rail portion 220.

[0037] Furthermore, the groove OG provided in the slide rail portion 200 has a taper inside the groove OG, so that the opening of the groove OG is opened wider than the diameter of the adjustment mechanism fitting portion 410. Therefore, the displacement between the vehicle body BD and the rear seat door RD is corrected by the adjustment mechanism fitting portion 410 and the groove OG.

[0038] On the other hand, when a distortion occurs between the vehicle body BD and the rear seat door RD and the adjustment mechanism fitting portion 410 fits into the slide rail portion 200 while correcting the position of the side glass portion 100 on the rear side of the vehicle toward the groove OG, the rear side of the vehicle of the side glass portion 100 moves in the vehicle vertical direction or the vehicle width direction from the state of FIG. 7(a) or FIG. 7(c). In other words, as shown in FIG. 7(b) or FIG. 7(d), an inclination α1 or α2 occurs in the vehicle vertical direction or the vehicle width direction with the pivot fitting portion 310 as a fulcrum between the side glass portion 100 and the slider base portion 330.

[0039] Here, the side glass fitting portion 130 in the side glass portion 100 is rotatably fitted to the pivot fitting portion 310. Therefore, when a displacement in the vehicle vertical direction occurs between the vehicle body BD and the rear seat door RD, as shown in FIG. 7(b), the side glass portion 100 rotates in the direction indicated by the arrow AR4 around the pivot fitting portion 310. When a displacement in the vehicle width direction occurs between the vehicle body BD and the rear seat door RD, as shown in FIG. 7(d), the side glass portion 100 rotates in the direction indicated by the arrow AR5 about the pivot fitting portion 310. Furthermore, as shown in FIG. 7(a), a gap d1 is ensured between the side glass portion 100 and the sliding portion 320. Therefore, even when the side glass portion 100 rotates about the pivot fitting portion 310, the side glass portion 100 does not interfere with the sliding portion 320. Therefore, the displacement between the vehicle body BD and the rear seat door RD is absorbed by the side glass fitting portion 130 and the pivot fitting portion 310.

[0040] The adjustment mechanism fitting portion 410 fitted in the groove portion OG moves the side glass portion 100 along the groove portion OG toward the rear side of the vehicle.

[0041] At the upper end rail portion 210, when a distortion occurs between the vehicle body BD and the rear seat door RD, a displacement also occurs between the upper end rail portion 210 and the side glass portion 100. When the displacement occurring between the upper end rail portion 210 and the side glass portion 100 is within the range of the opening at the upper end rail portion 210, the side glass portion 100 fits into the upper end rail portion 210 and slides on the upper end rail portion 210. Therefore, the displacement between the upper end rail portion 210 and the side glass portion 100 is adjusted by the side glass portion 100 being fitted into and guided by the wide opening of the upper end rail portion 210.

[0042] As described above, when an operation to open the side glass portion 100 is performed by the user, the adjustment mechanism fitting portion 410 having the substantially triangular pyramid-shaped through-hole TH is rotatably provided on the side glass portion 100 through the through-hole TH, so that the adjustment mechanism fitting portion 410 guides the side glass portion 100 in the direction of fitting it into the groove portion OG without a sense of incongruity. Furthermore, since the upper end rail portion 210 and the lower end rail portion 220 are provided with a taper, the slide rail portion 200 slides the side glass portion 100 toward the rear side of the vehicle without a sense of incongruity. When there is a displacement in the vehicle width direction between the vehicle body BD and the rear seat door RD, and when the long-axis apex MV in the adjustment mechanism fitting portion 410 is within the range of the groove portion OG, the adjustment mechanism fitting portion 410 rotates and moves in the vehicle vertical direction and the vehicle width direction, whereby the adjustment mechanism fitting portion 410 guides the side glass portion 100 in a direction to fit it into the groove portion OG. Furthermore, on the vehicle front side of the side glass portion 100, since the side glass fitting portion 130 and the pivot fitting portion 310 are rotatably fitted, the inclination generated between the side glass portion 100 and the slider base portion 330 is absorbed by the side glass fitting portion 130 and the pivot fitting portion 310. Then, the side glass portion 100 stops in a state where the side glass portion 100 shown in FIG. 5(a) is closed and changes to the state where the side glass portion 100 shown in FIG. 5(b) is opened. Since the side glass portion 100 moves to the vehicle rear side along the slide rail portion 200 fixed to the vehicle body BD and stops at a position in the opened state, the window frame portion in the rear seat door RD is in the opened state. When the window frame portion in the rear seat door RD is in the opened state, the occupant places luggage in the vehicle through the window frame portion having a sufficient opening range not restricted by the side glass portion 100.

[0043] (When closing the side glass portion 100) When the user closes the side glass portion 100, for example, an operation to close the side glass portion 100 is performed by a remote control key or a switch provided in the vehicle V. At this time, the side glass portion 100 is in the state shown in FIG. 5(b).

[0044] When an operation to close the side glass portion 100 is performed by the user, the drive portion DM in the side glass moving portion 300 rotates the slide shaft 340, and the sliding portion 320 moves toward the vehicle front side along the slider base portion 330. When the pivot fitting portion 310 coupled to the sliding portion 320 fits into the recess FH provided in the side glass fitting portion 130, the sliding portion 320 slides the side glass portion 100 toward the front side of the vehicle.

[0045] When the adjustment mechanism fitting portion 410 comes out of the groove portion OG in the slide rail portion 200, the side glass portion 100 is placed on the sliding pedestal 350. The position of the side glass portion 100 is corrected by the rib RT provided on the sliding pedestal 350, and the side glass portion 100 is placed substantially at the center in the vehicle width direction of the slider base portion 330. Then, the side glass portion 100 stops in the closed state shown in Fig. 5(b) from the open state shown in Fig. 5(a).

[0046] As described above, the vehicle side glass device 10 according to the present embodiment includes a side glass portion 100 that is provided on the upper side of the vehicle of the rear seat door RD in the vehicle V so as to be openable and closable, and is fixed to the vehicle body BD on the rear side of the vehicle at at least one of the upper end portion or the lower end portion of the side glass portion 100. A slide rail portion 200 that slides the upper end portion or the lower end portion of the side glass portion 100, a side glass moving portion 300 that is provided on the lower side of the vehicle of the side glass portion 100 and slides the side glass portion 100 in the vehicle front-rear direction, and a side glass portion 100 that is provided on the rear side of the vehicle of the side glass portion 100 and guides and fits the side glass portion 100 to the slide rail portion 200 when the side glass portion 100 is opened and closed. An adjustment mechanism portion 400, and the side glass moving portion 300 has a pivot fitting portion 310 that fits with the side glass portion 100 so that the angle can be changed in the vehicle vertical direction and the vehicle width direction. The adjustment mechanism portion 400 is provided on the side glass portion 100 so that the angle can be changed in the vehicle vertical direction and the vehicle width direction, and has an adjustment mechanism fitting portion 410 that fits and slides on the slide rail portion 200 when the side glass portion 100 moves toward the rear side of the vehicle. That is, when opening and closing the side glass part 100, the side glass moving part 300 rotatably fitted to the side glass fitting part 130 moves in the vehicle longitudinal direction via the sliding part 320. Then, the adjustment mechanism fitting part 410 provided in the adjustment mechanism part 400 fixed to the vehicle rear side of the side glass part 100 fits and slides on the slide rail part 200, whereby the side glass part 100 is opened and closed. When distortion occurs between the vehicle body BD and the rear seat door RD, a displacement occurs between the long axis apex part MV in the adjustment mechanism fitting part 410 and the groove part OG in the lower end rail part 220. When the long axis apex part MV is within the range of the groove part OG, the adjustment mechanism fitting part 410 rotates and moves toward the groove part OG, whereby the adjustment mechanism fitting part 410 is guided in the direction of fitting into the groove part OG. Furthermore, on the vehicle front side of the side glass part 100, since the side glass fitting part 130 and the pivot fitting part 310 are rotatably fitted, the inclination generated between the side glass part 100 and the slider base part 330 is absorbed by the side glass fitting part 130 and the pivot fitting part 310. Therefore, by moving the side glass part 100 along the slide rail part 200 fixed to the vehicle body BD without a sense of incongruity in the vehicle longitudinal direction, the vehicle side glass device 10 can easily bring the side glass part 100 in the rear seat door RD into an open state. Therefore, in a state where the rear seat door is closed, the side glass part can be easily brought into an open state.

[0047] Also, in the vehicle side glass device 10 according to the present embodiment, the adjustment mechanism fitting part 410 has an elliptical shape having a long axis in the vehicle longitudinal direction. That is, when the adjustment mechanism fitting portion 410 and the slide rail portion 200 are fitted, even when a distortion occurs between the vehicle body BD and the rear seat door RD, when the long axis apex portion MV on the rear side of the vehicle having an elliptical shape is within the range of the groove portion OG in the slide rail portion 200, the long axis apex portion MV is smoothly guided by the groove portion OG, whereby the positions of the adjustment mechanism fitting portion 410 and the slide rail portion 200 are adjusted. Therefore, the vehicle side glass device 10 can adjust the displacement between the side glass portion 100 and the slide rail portion 200 by the adjustment mechanism fitting portion 410 and the groove portion OG. And even when a distortion occurs between the vehicle body BD and the rear seat door RD, the vehicle side glass device 10 can open the side glass portion 100 without a sense of incongruity. Therefore, in a state where the rear seat door is closed, the side glass portion can be easily opened.

[0048] <Second Embodiment> The configuration of the vehicle side glass device 10A according to the present embodiment will be described with reference to FIGS. 8 to 13.

[0049] (Regarding the configuration of the vehicle side glass device 10A) As shown in FIG. 8, the vehicle side glass device 10A according to the present embodiment includes a side glass portion 100, a slide rail portion 200, a side glass moving portion 300, an adjustment mechanism portion 400, an angle adjustment portion 500, a position detection portion 600, and a control portion 700.

[0050] (Regarding the angle adjustment portion 500) The angle adjustment portion 500 is provided at at least one location in contact with the adjustment mechanism fitting portion 410 to adjust the angle of the adjustment mechanism fitting portion 410. The angle adjustment portion 500 is fixed to the rear seat door RD. As shown in Fig. 9, the angle adjustment unit 500 includes a bladder part 510 (bladder part 510U, bladder part 510L) that can expand or contract by internal pressure, a pressure adjustment unit 520 that adjusts the internal pressure of the bladder part 510, and a pressure transmission pipe CP that connects the bladder part 510 and the pressure adjustment unit 520 and sends internal pressure to the bladder part 510.

[0051] The bladder part 510 is a diaphragm formed in a bag shape by a member such as rubber that can contract, and expands or contracts by internal pressure. When the internal pressure rises, the bladder part 510 expands and the diameter of the bladder part 510 increases. When the internal pressure drops, the bladder part 510 contracts and the diameter of the bladder part 510 decreases. The bladder part 510 is provided, for example, on the outer side in the vehicle width direction on the upper side of the rear part of the vehicle and on the inner side in the vehicle width direction on the lower side of the front part of the vehicle at the adjustment mechanism fitting part 410. In a state where the bladder part 510 is contracted, the bladder part 510 is provided at a position where it does not contact the adjustment mechanism fitting part 410. In a state where the bladder part 510 is expanded, the bladder part 510 abuts against the adjustment mechanism fitting part 410. A pressure transmission pipe CP that connects the bladder part 510 and the pressure adjustment unit 520 is connected to the bladder part 510. The pressure transmission pipe CP is a hollow pipe-shaped tube formed of a member such as metal, resin, or silicon, and transmits the pressure adjusted by the pressure adjustment unit 520 to the bladder part 510.

[0052] The pressure adjustment unit 520 adjusts the internal pressure of the bladder part 510 based on information transmitted from the control unit 700. The pressure adjustment unit 520 is connected to the bladder part 510 via the pressure transmission pipe CP. The pressure adjustment unit 520 has, for example, a piston part and a cylinder part, and changes the pressure of the gas or hydraulic oil enclosed inside the cylinder by operating the piston part. The bladder part 510, the pressure adjustment unit 520, and the pressure transmission pipe CP are connected in a sealed state. Inside the connected bladder part 510, pressure adjustment unit 520, and pressure transmission pipe CP, a gas such as nitrogen or a hydraulic oil such as silicon oil is enclosed. The pressure adjustment unit 520 is fixed to the rear seat door RD.

[0053] A sliding pedestal 350, which will be described later, is provided at the vehicle rear side of the slider base portion 330. The vehicle rear end of the side glass portion 100 is placed on the upper side of the vehicle of the sliding pedestal 350. When the side glass portion 100 is opened, the side glass portion 100 slides on the upper side of the vehicle of the sliding pedestal 350.

[0054] (Regarding the position detection unit 600) The position detection unit 600 is provided on the rear seat door RD and acquires the position deviation information between the rear seat door RD and the vehicle body BD on the rear side of the vehicle. As shown in FIG. 10, the position detection unit 600 includes a position marker 610 provided on the rear side of the vehicle of the rear seat door RD and a marker detection unit 620 provided on the vehicle body BD on the rear side of the vehicle. The position marker 610 and the marker detection unit 620 are provided facing each other. When a distortion occurs between the vehicle body BD and the rear seat door RD, a position deviation occurs between the position marker 610 and the marker detection unit 620. The position detection unit 600 acquires the position deviation information generated between the position marker 610 and the marker detection unit 620.

[0055] The position marker 610 is provided at a position facing the vehicle body BD on the rear side of the vehicle of the rear seat door RD. The position marker 610 is, for example, an engraving or a label such as a trim mark or a dot mark, and is provided on the rear seat door RD.

[0056] The marker detection unit 620 detects information regarding the position deviation occurring between the rear seat door RD and the vehicle body BD in a state where the rear seat door RD is closed, and transmits the information regarding the position deviation to the control unit 700. The marker detection unit 620 detects information regarding the position deviation between the rear seat door RD and the vehicle body BD on the rear side of the vehicle by irradiating, for example, infrared rays or visible light toward the position marker 610 and acquiring information regarding the position of the position marker 610. The marker detection unit 620 transmits the detected information regarding the position deviation to the control unit 700.

[0057] (Regarding the control unit 700) The control unit 700 controls the angle adjustment unit 500 based on the information regarding the displacement transmitted from the position detection unit 600. As shown by the thick solid line arrows in FIG. 10, the control unit 700 is connected to the lock unit LK in the rear seat door RD, the angle adjustment unit 500, the position detection unit 600, the drive unit DM in the side glass movement unit 300, and the control CPU of the vehicle V (not shown).

[0058] (Processing of the control unit 700) The processing of the control unit 700 in the vehicle side glass device 10A according to the present embodiment will be described with reference to FIGS. 11 to 13.

[0059] (When opening the side glass unit 100) As shown in FIG. 11, the control unit 700, for example, acquires information from the control CPU of the vehicle V (not shown), and determines whether an operation to open the side glass unit 100 has been performed by the user. (Step S110).

[0060] When the control unit 700 determines that an operation to open the side glass unit 100 has not been performed by the user (''NO'' in step S110), the control unit 700 causes the process to transition to step S110.

[0061] On the other hand, when the control unit 700 determines that an operation to open the side glass unit 100 has been performed by the user (''YES'' in step S110), the control unit 700 releases the lock unit LK in the side glass unit 100 (step S120), and causes the process to transition to step S130.

[0062] The control unit 700 acquires information regarding the displacement between the rear seat door RD and the vehicle body BD on the rear side of the vehicle from the position detection unit 600, and determines whether there is a displacement (step S130).

[0063] When the control unit 700 determines that there is no misalignment (``NO'' in step S130), the control unit 700 causes the process to transition to step S150.

[0064] On the other hand, when the control unit 700 determines that there is misalignment (``YES'' in step S110), the control unit 700 controls the pressure adjustment unit 520 in the angle adjustment unit 500 based on the information regarding the obtained misalignment. Then, the control unit 700 adjusts the angle of the adjustment mechanism fitting part 410 by expanding or contracting the bladder part 510 via the pressure adjustment unit 520 (step S140).

[0065] As shown in FIG. 12, for example, when the position detection unit 600 acquires information indicating that a misalignment has occurred on the outer side of the lower part of the vehicle between the rear seat door RD and the vehicle body BD, the control unit 700 performs control to direct the long-axis apex part MV of the adjustment mechanism fitting part 410 toward the inner side of the upper part of the vehicle. Specifically, the control unit 700 performs control to expand the bladder part 510L provided on the inner side of the front part of the vehicle, and also performs control to expand the bladder part 510U provided on the outer side of the rear part of the vehicle so that its diameter becomes smaller than that of the bladder part 510L. The adjustment mechanism fitting part 410 rotates in the directions indicated by the arrow AR6 and the arrow AR7 around the fixed bar 420 by being pushed by the bladder part 510L and the bladder part 510U, thereby directing the long-axis apex part MV toward the inner side of the upper part of the vehicle. Then, the adjustment mechanism fitting part 410 accurately fits into the slide rail part 200.

[0066] Then, as shown in FIG. 11, the control unit 700 moves the side glass part 100 toward the rear side of the vehicle by rotating the drive unit DM in the side glass moving unit 300 (step S150). The adjustment mechanism fitting part 410 adjusted by the control unit 700 fits into the groove part OG provided inside the lower end rail part 220, and the adjustment mechanism fitting part 410 slides the lower end rail part 220 toward the rear side of the vehicle.

[0067] The control unit 700 determines whether or not the side glass unit 100 is in an open state (step S160). When the control unit 700 determines that the side glass unit 100 is not in an open state ( "NO" in step S160), the control unit 700 causes the process to transition to step S160.

[0068] On the other hand, when the control unit 700 determines that the side glass unit 100 is in an open state ( "YES" in step S160), the control unit 700 stops the side glass unit 100 by stopping the drive unit DM (step S170), and ends the process.

[0069] (When closing the side glass unit 100) As shown in FIG. 13, the control unit 700 acquires information from, for example, a control CPU of a vehicle V (not shown), and determines whether or not an operation to close the side glass unit 100 has been performed by the user. (Step S210).

[0070] When the control unit 700 determines that the user has not performed an operation to close the side glass unit 100 ( "NO" in step S210), the control unit 700 causes the process to transition to step S210.

[0071] On the other hand, when the control unit 700 determines that the user has performed an operation to close the side glass unit 100 ( "YES" in step S210), the control unit 700 moves the side glass unit 100 toward the front side of the vehicle by rotating the drive unit DM (step S220), and causes the process to transition to step S230.

[0072] The control unit 700 determines whether or not the side glass unit 100 has been housed in the rear seat door RD (step S230). When the control unit 700 determines that the side glass unit 100 has not been housed in the rear seat door RD ( "NO" in step S230), the control unit 700 causes the process to transition to step S230.

[0073] On the other hand, when the control unit 700 determines that the side glass unit 100 has been stored in the rear seat door RD ( "YES" in step S230), the control unit 700 stops the side glass unit 100 by stopping the drive unit DM (step S240) and ends the process.

[0074] <Function and Effect> As described above, the vehicle side glass device 10A according to the present embodiment is fixed to the rear seat door DR, provided at least at one location in contact with the adjustment mechanism fitting portion 410, and includes an angle adjustment portion 500 that adjusts the angle of the adjustment mechanism fitting portion 410, and a control unit 700 that controls the angle adjustment portion 500. The angle adjustment portion 500 is provided with a bladder portion 510 that is in contact with the adjustment mechanism fitting portion 410 and can expand or contract by internal pressure, and a pressure adjustment portion 520 that adjusts the internal pressure of the bladder portion 510 based on information transmitted from the control unit 700. That is, when the side glass unit 100 is opened, based on the information transmitted from the control unit 700, the pressure adjustment portion 520 adjusts the bladder portion 510. Then, the control unit 700 controls the direction of the major axis apex portion MV in the adjustment mechanism fitting portion 410 that is in contact with the bladder portion 510 by expanding or contracting the bladder portion 510 via the pressure adjustment portion 520. The adjustment mechanism fitting portion 410 controlled by the control unit 700 accurately fits into the groove portion OG provided inside the lower end rail portion 220, and the adjustment mechanism fitting portion 410 slides smoothly toward the rear side of the vehicle along the lower end rail portion 220. Therefore, even when a distortion occurs between the vehicle body BD and the rear seat door RD, the control unit 700 can accurately fit the adjustment mechanism fitting portion 410 into the slide rail portion 200, and the vehicle side glass device 10A can further open the side glass unit 100 without any discomfort. Therefore, in a state where the rear seat door is closed, the side glass unit can be easily opened.

[0075] The side glass device 10A for a vehicle according to this embodiment further includes a position detection unit 600 that acquires the positional deviation information between the rear seat door RD and the vehicle body BD on the rear side of the vehicle in the rear seat door DR, and the control unit 700 controls the angle adjustment unit 500 based on the positional deviation information of the rear seat door RD transmitted from the position detection unit 600. That is, when the side glass part 100 is opened, the control unit 700 controls the expansion or contraction of the bladder part 510 in the angle adjustment unit 500 based on the information regarding the positional deviation between the rear seat door RD and the vehicle body BD on the rear side of the vehicle transmitted from the position detection unit 600. The control unit 700 controls the direction of the long axis apex part MV in the adjustment mechanism fitting part 410 based on the more accurate and detailed information regarding the positional deviation transmitted from the position detection unit 600. Therefore, even when a distortion occurs between the vehicle body BD and the rear seat door RD, the control unit 700 can further accurately fit the adjustment mechanism fitting part 410 to the slide rail part 200, so that the vehicle side glass device 10A can open the side glass part 100 in a more natural state without a sense of incongruity. Therefore, when the rear seat door is closed, the side glass part can be easily opened.

[0076] When the side glass part 100 is not closed, the control unit 700 may prohibit the opening and closing of the rear seat door RD.

[0077] <Modification Example> In this embodiment, the bladder part 510 in the angle adjustment unit 500 is illustrated as being provided on the front and rear sides of the vehicle of the adjustment mechanism fitting part 410. However, for example, as shown in FIG. 14, the bladder part 510 may be provided at one location on the front side of the vehicle of the adjustment mechanism fitting part 410, and the rear side of the adjustment mechanism fitting part 410 may be biased by a spring SP. The outer side in the vehicle width direction of the spring SP is fixed to the door glass frame 120 or the angle adjustment unit 500, and the inner side in the vehicle width direction of the spring SP abuts against the adjustment mechanism fitting part 410.

[0078] As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and designs and the like within the scope not departing from the gist of the present invention are also included.
