Referring to this, the arm type window regulator 10 includes a mounting plate 12 fixed to a predetermined position on the inner surface of the door, a driving motor 14 installed on the mounting plate 12, and the driving motor 14. A drive gear 16 that is rotated in a forward or reverse direction according to a driving direction of the main gear 18, the main arm 18 pivotally coupled over a predetermined angle range at one end of the mounting plate 12, and the main arm 18 Fixedly coupled to the lower end, and coupled to the drive gear 16 and rotated to intersect the center gear of the sector gear 20 and the main arm 18 which impart rotational force to the main arm 18. And a sub-arm 22 which is rotated in a direction opposite to the main arm 18, a slider 24 coupled to an upper end of the main arm 18 and the sub-arm 22 and a lower end of the sub-arm, and a window glass ( 26) is fixed to the lower end and standing with the main arm (18) Slider 24 coupled to the upper end of the arm 22 is inserted and coupled to move horizontally, the upper guide rail 28 for opening and closing the window glass 26 while being elevated in accordance with the horizontal movement of the slider, and the sub The slider coupled to the lower end of the arm 22 is composed of a lower guide rail 30 is fitted so as to move horizontally.

In such a general window regulator 10, the drive motor 14 is configured to be driven in the forward or reverse direction in accordance with the switching operation of the occupant in the state connected to the power supply inside the vehicle.

In addition, the drive gear 16 is installed to be rotated in accordance with the drive direction of the drive motor in the state of being mechanically engaged with the shaft of the drive motor 14, the sector gear 20 is at the lifting height of the window glass 26. It is formed at the corresponding angle.

The operation state of the arm type window regulator made as described above is as follows.

When the occupant wants to open or close the window glass 26, and if the operation switch (not shown) is operated in the desired direction, the driving motor 14 is driven in the predetermined direction by the switching operation and at the same time, The mechanically coupled drive gear 16 is rotated in the same direction.

Referring to this, in the conventional arm type window regulator 10, the slider 24 coupled to both ends of the main arm 18 and the sub arm 22 is formed of a simple rectangle, an ellipse, or a simple cylindrical shape. In the state where 24 is fitted to the guide rails 28 and 30, the upper and lower surfaces and the entire rear surface are in close contact with each corresponding surface on the guide rail.

Therefore, since the friction area between the slider 24 and the inner surface of the guide rail is increased, friction noise is generated during the sliding movement, and the operation feeling thereof becomes very poor.

In addition, when the outer surface of the slider that is in contact with the inner surface of the guide rail wears out due to use for a certain period of time, as the gap is worn out, the bearing capacity is weakened and the slider needs to be replaced with a new one. There is.

If the support force of the slider is weakened and it is not replaced with a new one, it may cause vibration noise due to vibration.

The purpose of the present invention is to improve the structure of the slider that is horizontally moved along the guide rail by being mounted at the tip of the main arm and the sub arm in the arm type window regulator so that friction noise on the inner surface of the guide rail is not generated. In addition, it is possible to provide a slider of a window regulator that can significantly improve the operating feeling at the time of sliding movement, and to automatically compensate for the worn size even if it is worn down for a certain period of time.

In order to achieve the above object, the present invention is hinged to the main arm and the sub-arm cross each other, the driving of the drive motor in the state in which the slider is inserted into the upper and lower guide rails and slides are coupled to the front end of each arm; In the arm type window regulator configured to move the window glass by the movement of the slider on the guide rail at the same time toward the center or spread outward on the guide rail, the slider is the upper and lower height and the front and rear thickness of the inner surface of the guide rail It is made of a hexahedral shape having a size that is in contact with, the central portion of the left and right sides and the upper and lower surfaces of the back is formed integrally with a plurality of cushioning pieces projecting outwards, respectively, with the incision hole therebetween, the incision has its own elasticity The cushioning material is filled.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

3 is an enlarged perspective view illustrating the slider of the window regulator according to the present invention.

Referring to this, the slider 24 coupled to the tip ends of the main arm 18 and the sub arm 22 has a cube shape in which the upper and lower heights and the front and rear thicknesses are in contact with the inner surfaces of the guide rails 28 and 30. It is made of, and has a structure in which a plurality of cushion pieces 40 protruding outwards are integrally formed in both the left and right sides and the upper and lower centers of the back surface.

In addition, a cutting hole 50 having a predetermined size is formed between each of the cushion pieces 40 and the slider body formed on the rear surface and the upper and lower surfaces of the slider 24, and the cutting hole 50 has a material itself such as rubber. The cushion material 60 having elasticity is filled.

In the center of the slider 24, a coupling hole 70 for coupling with the main arm 18 or the sub arm 22 is formed.

Figure 4 is a side cross-sectional view showing a coupling state and an operating state of Figure 3, Figure 5 is a front view showing a coupling state and the operating state of FIG.

Referring to this, when the slider 24 is fitted to the inside of the guide rails 28 and 30 in a state in which the slider 24 is mounted at the tip end of the main arm 18 or the sub arm 22, the upper and lower surfaces of the slider 24 are located. And each cushion piece 40 formed in the bowel movement is in contact with the corresponding inner surface on the guide rail in point contact method.

In order to raise and lower the window glass 26 in such a coupled state, when the operation switch (not shown) is operated in a predetermined direction, the driving motor 14 shown in FIG. 1 is rotated in the predetermined direction by the switching operation. At the same time, the drive gear 16 is rotated in the same direction, and the sector gear 20 meshed with the drive gear 16 is rotated in the predetermined direction.

When the sector gear 20 is rotated as described above, the sliders 24 fixed to the ends of the main arm 18 and the sub arm 22 are collected toward the center at the same time along the upper and lower guide rails 28 and 30 or the edges thereof. And the window glass 26 fixed to the upper guide rail 28 is opened and closed as the height of the main arm 18 and the sub arm 22 are changed.

In the lifting and lowering operation of the window glass 26, the inner surface of each of the guide rails 28 and 30 and the cushion piece 40 on the slider 24 are in contact with the minimum area, and the cushion piece 40 and The friction noise is not generated by the elasticity of the cushioning material 60 filled in the cutting hole 50, and the operation feeling is remarkably improved.

In addition, if the cushion piece 40 is assembled in a slightly compressed state when assembling the slider 24, the cushion piece 40 formed on the outer surface of the slider is formed between the slider body and the cushion piece even when the slider piece is worn. It protrudes outward as much as the worn size by the elastic force of the cushioning material 60 filled in the incision hole (50).

When the present invention is applied, a plurality of cushion pieces protrude from the back and top and bottom of the slider which slides along the guide rail in the arm type window regulator, and the inside of the incision hole providing elastic force to the cushion pieces has its own elasticity. As the cushioning material is filled, friction noise is not generated as the sliding contact is made while contacting each inner surface of the guide rail in a point contact manner.

In addition, when the sliding movement is significantly improved by minimizing the friction area, and the cushion piece is first assembled to be slightly compressed, even if the cushion piece is worn after being used for a period of time, as much as the elasticity of the cushion material filled in the incision is worn out, As the dimensions are automatically corrected, the life of the slider is extended.
