[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a window regulator that guides the lifting and lowering of the windshield with an arm. When a load is applied during the raising process of the windshield, the power transmission from the arm to the windshield is interrupted and the rise of the windshield is stopped. Regarding the structure.

[0002]

[Prior art]

 As a window regulator, for example, as described in “Automotive Engineering Complete Book 13: Car Body of Passenger Car” published on October 15, 1980 by Sankaido Co., Ltd., pages 134 to 137, the rotation of the driving shaft can be changed. There is known a so-called arm-type window regulator in which the window glass is moved up and down with respect to the door main body by swinging the arm in the up-down direction via a pinion gear and a sector gear by driving.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, during the process of raising the arm, the occupant may be caught between the window glass and the upper edge of the sash in the door with sash, or between the window glass and the upper edge of the vehicle body side in the sashless door. Part of the body such as the hand or head of the person may be caught. In such a case, with a manual method of manually rotating the driving shaft, the rotation of the driving shaft is stopped with the operator's consciousness, and it is comparatively less important, but the driving shaft is rotated by a motor. In the formula, since it is necessary to maintain the sealability of the windshield with the weather strip at the upper limit position where the windshield is fully closed, the motor in the fully closed position is set to the motor during the process of raising the windshield. Even if a load smaller than the load is applied, the power of the motor is turned off or the motor is rotated in reverse to reduce the burden on the occupant who has a part of his body caught. I want to.

In view of this, in the present invention, in the arm type window regulator, a load is applied to the windshield, such as the occupant's hand or head being caught in a part of the body during the process of raising the windshield. In this case, the issue is to improve the safety of the occupant by blocking the power transmission from the arm to the windshield.

[0005]

[Means for Solving the Problems]

 A first invention is that a driving shaft for outputting an opening / closing force of a window glass and a base end portion of an arm whose tip portion is connected to the window glass are rotatably attached to a base plate assembled to a door body. A pinion gear is mounted on the driving shaft, a sector gear meshing with the pinion gear is coupled to the arm, and the driving shaft is rotationally driven to swing the arm up and down through the pinion gear and the sector gear. In a window regulator that raises and lowers the glass with respect to the door body, divides the arm into a sector gear side arm and a window glass side arm, and divides the sector gear side arm and the window glass side arm with the same axis. While these are rotatably connected, Normally, the window side arm and the sector gear side arm are engaged so that the rotation of the window glass side arm can be regulated, and if a load is applied during the ascending process of the window glass, the window glass side arm is centered on the same axis. An engaging / disengaging mechanism for disengaging the downward bending is provided.

According to a second aspect of the invention, in the engagement / disengagement mechanism of the first aspect, an elongated hole formed in the window glass side arm, a pin movably mounted in the elongated hole, and the pin formed into the elongated hole. When the spring for biasing the same axis and the sector gear side arm are normally engaged with the pin to restrict the rotation of the window glass side arm and a load is applied in the ascending process of the window glass. A detachment groove that allows the pin to be moved along the elongated hole to be detached so that the windshield side arm can be bent downward about the same axis, and a rising limit of the windshield formed on the base plate. And a retaining groove for restricting the removal of the pin from the detachment groove in the immediately preceding position.

[0007]

[Action]

 According to the first invention, when a load is applied to the window glass during the ascending process of the window glass, the operation of the engagement / disengagement mechanism causes the window glass side arm to move the same shaft connecting with the sector gear side arm. It is bent downward as the center. Also, in the normal process of reaching the upper limit position of the windshield without inadvertently loading the windshield during the process of raising the windshield, the engagement / disengagement mechanism does not operate and the windshield side arm is not activated. The rotation of the arm and the sector gear side arm remains restricted, and the window glass is fully closed.

In the second device, in addition to the first device, the engagement / disengagement mechanism operates by mechanical power transmission due to the load applied to the windshield. In other words, when a load greater than the elastic force of the spring is applied to the wind glass, the wind glass side arm pushes the pin and moves along the elongated hole against the bias of the spring to separate from the separation groove. This releases the unification of the sector gear side arm and the window glass side arm that were engaged by the pin, and the window glass side arm bends downward with respect to the sector gear side arm about the same axis.

【Example】

 First Embodiment FIG. 1 shows a side surface of a passenger car using an X-arm type window regulator as a first embodiment. In FIG. 1, the vehicle body side portion 1 is formed with an opening portion 2 for passenger occupancy. A door body 4 of a door 3 is attached to the opening 2 via a hinge 5 so as to be opened and closed laterally of the vehicle body. A window glass 6 is attached to the door body 4 so that the window glass 6 can be lifted (opened and closed) by a window regulator 7 stored in the door body 4. The base plate 8 assembled to the door body 4 of the window regulator 7 has a driving shaft 9 for outputting the opening / closing force of the window glass 6 and a base end portion of a main arm 10 as an arm whose tip is connected to the window glass 6. And are rotatably attached. The driving shaft 9 is connected to an output shaft of a motor 11 attached to the base plate 8 through a worm wheel mechanism (not shown), and a pinion gear 12 that rotates in a reverse rotation preventing mechanism (not shown) is attached to the driving shaft 9. is there. The sector gear 13 meshing with the pinion gear 12 is coupled to the main arm 10. The main arm 10 is divided into a sector gear side arm 14 provided with the sector gear 13 and a window glass side arm 15 to which the window glass 6 is connected. The split ends of the sector gear side arm 14 and the window glass side arm and 15 are rotatably connected by a support shaft 16 which is the same axis. The support shaft 16 is attached to the base plate 8. A roller 17 is attached to the tip of the window glass side arm 15. The roller 17 is slidably engaged with a glass bottom channel 18 fixedly attached to the lower edge of the window glass 6. A sub-arm 19 for assisting the window glass 6 to move up and down while keeping horizontal is provided at an intermediate portion between the roller 17 of the window glass side arm 15 and the support shaft 16 so as to be rotatable in an X shape by a pin 20. It is connected. The sub-arm 19 is actually composed of two arm members, but these two arm members are joined together by a pin 20 so as to be non-rotatable with the window glass side arm 15 interposed therebetween. The rollers 21 and 22 are individually attached to the upper end and the lower end of the sub-arm 19. The roller 21 at the upper end is slidably engaged with the glass bottom channel 18. The roller 22 at the lower end is slidably engaged with the arm guide channel 23. The arm guide channel 23 is attached to the door body 4 at substantially the same height as the base plate 8. An engagement / disengagement mechanism 30 is provided on the window glass side arm 15 and the sector gear side arm 14.

FIG. 2 shows the engagement / disengagement mechanism 30. In FIG. 2, the engagement / disengagement mechanism 30 normally engages so as to regulate the rotation of the window glass side arm 15, and when a load is applied during the process of raising the window glass 6, the engagement / disengagement mechanism 30 supports the window glass side arm 15. It is designed so that it can be bent downward around 16 as a center. Specifically, the engagement / disengagement mechanism 30 includes a long hole 31 formed in the window glass side arm 15, a pin 32 movably mounted in the long hole 31, and a pin 32 from the support shaft 16 to the support shaft 16. The spring 33 is provided so as to extend over it, the disengagement groove 34 formed in the arm 14 on the sector gear side, and the retaining groove 35 formed in the base plate 8. The spring 33 biases the pin 32 toward the support shaft 16 side of the elongated hole 31. The disengagement groove 34 is V-shaped, and normally engages with the pin 32 biased by the spring 33, and is centered on the support shaft 16 of the window glass side arm 15 with respect to the sector gear side arm 14. The rotation of the window glass side arm 15 and the sector gear side arm 14 are integrally connected like a single arm member. Then, when a load is applied to the release groove 34 during the ascending process of the windshield 6, the windshield side arm 15 pushes the pin 32, so that the pin 32 resists the bias of the spring 33 and follows the elongated hole 31. The window glass side arm 15 with respect to the sector gear side arm 14 can be bent downward around the same shaft 16 as the center. An arc-shaped guide 36 centered on the support shaft 16 is formed at the end edge of the sector gear side arm 14 located below the detachment groove 34. The retaining groove 35 restricts the pin 32 from coming out of the removal groove 34 at the upper limit position (fully closed position) of the window glass 6.

According to the first embodiment, normally, as shown in FIG. 3, the pin 32 is biased by the spring 33 toward the support shaft 16 side of the elongated hole 31 and positioned in the detachment groove 34. The rotation of the window glass side arm 15 with respect to the sector gear side arm 14 is restricted, and the sector gear side arm 14 and the window glass side arm 15 are integrated into one main arm 10. In this state, when the driving shaft 9 is rotationally driven by the motor 11, the main arm 10 swings up and down around the support shaft 16 via the pinion gear 12 and the sector gear 13 to swing the main arm 10. In accordance with the movement, the sub arm 19 also swings vertically along the arm guide channel 23 around the pin 20, and the roller 17 of the window glass side arm 15 and the roller 21 of the sub arm 19 move in the glass bottom channel 18. While sliding, the glass bottom channel 18 is moved up and down to move the window glass 6 up and down with respect to the door body 4.

Then, in the process of raising the windshield 6, a part of the body such as a hand or a head of an occupant is provided between the windshield 6 and the upper edge of the sash or between the windshield 6 and the side portion of the vehicle body. When the windshield 6 is subjected to a load equal to or greater than the elastic force of the spring 33 such as when the windshield 6 is pinched, the windshield side arm 15 bends downward around the supporting shaft 16 as shown in FIG. In other words, when the wind glass 6 is loaded with a force equal to or greater than the elastic force of the spring 33, the wind glass side arm 15 pushes the pin 32 and moves along the long hole 31 against the bias of the spring 33, and the release groove 3 is moved. It is disengaged from No. 4 and moved to the guide 36 of the sector gear side arm 14. As a result, the integration of the sector gear side arm 14 and the window glass side arm 15 of the main arm 10 which has been engaged by the pin 32 is released, and the window glass side arm 15 and the sector gear side arm 14 have the same axis 16 Bend downwards around. Therefore, it is possible to eliminate the inconvenience that the occupant is injured or the like without exerting an unreasonable force on the occupant whose part of the body such as the hand or the head is sandwiched.

In addition, in parallel with the bending of the window glass side arm 15, the ascending driving force of the motor 11 is transmitted to the sector gear side arm 14 via the pinion gear 12 and the sector gear 13, but the pin 32 is used. Since the sector gear side arm 14 and the windshield side arm 15 are released from the unification, the sector gear side arm 14 swings upward with the support shaft 16 as the center. Therefore, it is possible to prevent the motor 11 from being overloaded, and the life of the motor 11 is extended.

On the other hand, in the process of raising the windshield 6, the windshield 6 is not subjected to a load equal to or greater than the elastic force of the spring 33, and the windshield 6 may or may not contact the weather strip (not shown) in a normal operation. When reaching the position just before the barrel rising limit, as shown in FIG. 5, the pin 32 is engaged with the elongated hole 31 and the detachment groove 34 by the spring 33, and the sector gear side arm 14 and the windshield side arm 15 are integrated. As it is, the pin 32 is positioned in the retaining groove 35 of the base plate 8. Then, at the upper limit position of the windshield 6, a load larger than the elastic force of the spring 33 acts on the windshield 6 to secure the sealing property with the weather strip (not shown), but at this time, the pin 32 comes off. It is located inside the stop groove 35 and cannot escape from the separation groove 34, so that the sector gear side arm 14 and the window glass side arm 15 are secured together. As a result, the window glass 6 is fully closed in a normal state.

In the first embodiment, the pin 32 is disengaged from the disengagement groove 34 due to the load acting on the window glass 6 during the ascending process of the window glass 6, and the window glass side arm 15 moves the support shaft 16 onto the support shaft 16. When it bends downward as the center, as shown in FIG. 6, the windshield side arm 15 is located at the lowermost end due to the weight of the windshield 6, but in this case, the motor 11 is placed in the windshield. It can be automatically repaired by driving in the downward direction of 6 with electric power. That is, when the sector gear side arm 14 swings to the lower limit position about the support shaft 16 by the electric power driving of the motor 11 in the descending direction, the disengagement groove 34 is aligned with the elongated hole 31, and the pin 32 is aligned. Is moved to the support shaft 16 side of the elongated hole 31 by the spring 33 and is positioned in the disengagement groove 34, so that the sector gear side arm 14 and the window glass side arm 15 are automatically integrated by the pin 32 into a normal state. .

Second Embodiment In this second embodiment, a spring as a means for urging the pin 32 of the disengagement mechanism 30 toward the support shaft 16 side of the elongated hole 31 is balanced with respect to its own weight of the windshield 6. The feature is that the spring 40 is used. Therefore, in this second embodiment, the main part shown in FIG. 7 will be described. In the description of the second embodiment, the same parts as those in the first embodiment are designated by the same reference numerals.

In FIG. 7, the balancing spring 40 is formed as a spiral spring, and the inner end thereof is formed at one end of a support shaft 16 that rotatably connects the sector gear side arm 14 and the window glass side arm 15. It is connected in the slit 41. A semicircular receiving portion 42 is formed on the outer end of the balancing spring 40. A pin 32 movably inserted into the long hole 31 of the window glass side arm 15 is engaged with the receiving portion 42.

Therefore, according to the second embodiment, normally, the pin 32 is urged in the swinging direction of the main arm 10 of the balancing spring 40 above the supporting shaft 16 side of the elongated hole 31. The arm 14 is biased to the position where it is positioned in the disengagement groove 34 of the sector gear side arm 14, and the sector gear side arm 14 and the window glass side arm 15 are integrated. Then, when the wind glass 6 is loaded with a force equal to or greater than the elastic force of the balancing spring 40 in the process of raising the wind glass 6, the wind glass side arm 15 pushes the pin 32. Then, the receiving portion 42 of the balancing spring 40 moves in the outer diameter direction of the balancing spring 40, the balancing spring 40 performs a diameter reducing operation, and the pin 32 moves along the long hole 31 against the bias of the balancing spring 40. At the same time, it separates from the separation groove 34 and moves to the guide 36 of the sector gear side arm 14. As a result, the sector gear side arm 14 and the window glass side arm 15 of the main arm 10 which are engaged with each other by the pin 32 are released from integration, and the window glass side arm 15 is coaxial with the sector gear side arm 14. Bend downwards around 16. In addition, when the windshield 6 does not receive a load equal to or greater than the elastic force of the spring 33 during the process of raising the windshield 6, and the windshield 6 reaches the position immediately before the upper limit of the rise in normal operation, the pin 32 causes the sector gear side gear to move. The pin 32 is located in the retaining groove 35 of the base plate 8 and cannot be removed from the detaching groove 34 while the frame 14 and the window glass side arm 15 are integrated. Integration with 15 is secured.

In short, according to the second embodiment, when a part of the body such as the hand or the head of the occupant is caught in the process of raising the windshield 6, the windshield side arm 15 bends. No undue force is applied to the occupant, upward swing of the sector gear side arm 14 is not restricted, and the motor 11 is not overloaded. When the upper limit position of the windshield 6 is reached, the sector gear side arm 14 and the windshield side arm 15 are kept united to ensure the sealing property of the windshield 6 with the weather strip. Of course. In addition, when the windshield side arm 15 is bent due to a part of the body such as the occupant's hand or head being pinched during the process of raising the windshield 6, the elastic force of the balancing spring 40 is applied to the windshield side arm 15. Because of the action, the window glass side arm 15 can be prevented from swinging about the support shaft 16 to the lowermost end by the weight of the wind glass 6.

Third Embodiment This third embodiment is characterized in that the pin 50 of the disengagement mechanism 30 is engaged and disengaged by an electromagnetic actuator. Therefore, the third embodiment will explain the main part shown in FIG. In the description of the third embodiment, the same parts as those in the first embodiment are designated by the same reference numerals.

In FIG. 8, the sector gear side arm 14 and the window glass side arm 15 are integrally engaged by a pin 50, and the electromagnetic actuator 51 is attached to one of the sector gear side arm 14 or the window glass side arm 15. When a load smaller than the load in the fully closed position is applied to the window glass 6, the electromagnetic actuator 51 is driven by electric power, and the pin 50 is driven by the electromagnetic actuator 51 to drive the pin 50 to the sector gear side arm 14 or the window glass side arm 15. The armature 14 on the sector gear side and the arm 15 on the window glass side are uncoupled from each other.

According to the third embodiment, by using the electromagnetic actuator 51, it is possible to omit the elongated hole 31, the release groove 34, and the retaining groove 35 as shown in FIG.

The present invention can be applied to a window regulator such as a one-arm type or a parallel-arm type other than the X-arm type.

[0024]

As described above, according to the first invention, when a load is applied to the window glass during the ascending process of the window glass, the operation of the engagement / disengagement mechanism causes the window glass side arm to move toward the sector gear side. Even if the arm on the sector gear side oscillates upward when it is bent downward around the same axis that is connected to the arm, the oscillating upward of the window glass side arm is stopped and the rise of the window glass stops. Therefore, when a part of the body such as the occupant's hands or head is caught in the process of climbing the windshield and a load is applied to the windshield, the power transmission from the arm to the windshield is blocked, The safety of passengers can be improved. Also, in the normal process of reaching the ascending limit position of the window glass without inadvertently applying a load to the window glass during the ascending process of the window glass, the engagement / disengagement mechanism does not operate and the window glass side Since the rotation of the arm and the arm on the sector gear side remains restricted, it is possible to ensure that the windshield is fully closed.

In the second device, in addition to the first device, the engagement / disengagement mechanism operates by mechanical power transmission due to the load applied to the windshield. In other words, when a load greater than the elastic force of the spring is applied to the wind glass, the windshield side arm pushes the pin and moves along the long hole against the biasing force of the spring, and separates from the release groove. This releases the unification of the sector gear side arm and the window glass side arm that were engaged by the pin, and the window glass side arm bends downward with respect to the sector gear side arm about the same axis. Therefore, when bending the windshield side arm, a drive source dedicated to bending other than the drive force for raising and lowering the windshield can be omitted, and the structure is simplified.
