Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a window regulator suitable for an automobile.

[0002]

[Prior art]

 Generally, a window panel of an automobile can be moved up and down by a lifting device such as a window regulator, and FIG. 8 shows the lifting movement of the window panel 101.

The window panel 101 is curved corresponding to the body shape of the vehicle body, and is adapted to move up and down along an ascending / descending trajectory along a curved panel surface.

[0004]

[Problems to be solved by the device]

 As described above, since the window panel 101 is curved along the body shape of the vehicle body, the window regulator 101 moves largely in the vehicle width direction from the ascending / descending locus during the ascending / descending process, as indicated by the chain line. The 103 can be deformed in the vehicle width (arrow) direction as shown by a chain line and a solid line so that it can follow the movement of the window panel 103 to some extent while ensuring support rigidity.

However, in recent years, since the body shape of the vehicle body has a rounded shape, the bending rate of the window panel 101 also increases, and the movement away from the ascending / descending trajectory tends to increase.

Therefore, in the arm type window regulator 103 having a high support rigidity, it is currently difficult to follow the movement of the window panel 101 that largely moves in the vehicle width direction when moving up and down.

Therefore, for example, when connecting the main channel 105 that supports the window panel 101 and the main arm 107 that raises and lowers the main channel 105, the mounting position of the arm 107 is set in the vehicle width (arrow) direction. It is necessary to set it so that it is almost in the middle of the range of motion that moves to, and accurate mounting management is required. If the user neglects to manage the attachment, displaces from the neutral position, and attaches it to the inner side (left side in the drawing) or the outer side (right side in the drawing), the amount of movement of the main arm 107 on the side of the deviation increases. This amount of movement in the vehicle width direction exceeds the allowable deformation amount of the main arm 107 in some cases, resulting in damage or unfavorable durability such as accelerated fatigue of the material.

Therefore, an object of the present invention is to provide a vehicle window regulator that can be moved up and down without being affected by the movement amount of the window panel in the vehicle width direction.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a main channel in which a window panel is supported, a sub-channel arranged substantially parallel to the main channel and attached to a door side, one end being a main channel and the other end being The sub-arms are respectively supported by the sub-channels through the connecting means, the front end side is supported by the main channel through the connecting means, and the base end side is rotatably supported by the base plate attached to the door side. In a window regulator including a main arm pivotally attached to the sub-arm in an X shape, and a drive motor that gives rotational power to a pinion that meshes with a sector gear provided on the base end side of the main arm, the connecting means is provided for each channel. A roller movably provided inside, one end of which is coupled to and supported by the roller and the other end of which Respect, are constituted by a slidably fitted supported shaft Kurumahaba direction.

[0010]

[Action]

 According to such a window regulator, the rotary power from the drive motor is transmitted to the main arm, so that the roller moves along the main channel and the sub-channel, and the standing angle between the main arm and the sub-arm coupled in an X-shape. Changes and the window panel can be moved up and down. When the window panel moves in the vehicle width direction during this elevating operation, the shaft slides in the vehicle width direction relative to the main arm and the sub arms in response to the amount of movement, and as a result, no deformation of each arm occurs. . Therefore, a stable lifting operation can be obtained over a long period of time without difficulty.
