[Field of the Invention]
The present invention relates to an armrest device for a sliding door that can be installed in a sliding door of a vehicle such as a passenger car and can be stored and deployed automatically in conjunction with an opening / closing operation of the sliding door.
[0002]
[Prior art]
Conventionally, in a vehicle such as a passenger car, an armrest for securing passenger comfort is attached to an inner portion of a door, that is, a door trim. The door of the vehicle provided with this armrest is a so-called rotary door that is pivotally supported by the vehicle body. 2. Description of the Related Art In recent years, a sliding door that is opened and closed by sliding in the front-rear direction of the vehicle body on the side surface of the vehicle body is known as a vehicle door in order to improve the ease of getting on and off in a small space. The sliding door is supported so as to slide in the front-rear direction of the vehicle in a state where it is lifted to the outside of the side surface of the vehicle.
[0003]
[Problems to be solved by the invention]
However, conventionally, an armrest is not installed on a sliding door of a vehicle.
Therefore, consider installing an armrest on the current sliding door.
FIG. 9 is a cross-sectional view when an armrest is installed on a current sliding door. In the figure, 1 is a sliding door, 2 is a door trim, 3 is an armrest, 4 is a body, a biaxial arrow H indicates an upper direction, and an arrow W indicates a width direction. The connecting member with the body 4 is not shown.
[0004]
Although the armrest 3 can be installed at a predetermined portion of the current door trim 2 inside the sliding door 1, the armrest 3 protrudes inside the sliding door 1 as shown in FIG. The sliding door 1 cannot be completely slid by colliding with the body 4. That is, the armrest 3 prevents the sliding door 1 from opening.
[0005]
Therefore, in order to avoid this obstacle, it can be considered that the shift amount of the slide door 1 is increased in the width direction W as shown in FIG. In the figure, 5a is an upper arm, 5b is a center arm, and 5c is a lower arm. The other reference numerals are the same as those in FIG. Thereby, the collision between the armrest 3 and the body 4 can be avoided, and as a result, the slide door 1 can be opened and closed. However, the rigidity of each arm 5a, 5b, 5c of the slide door 1 is lowered. That is, as shown in FIG. 10B, each arm 5a, 5b, 5c is loosened and deformed by its own weight, and it becomes difficult to slide the slide door 1 itself, and it cannot be used. It will cause another problem.
[0006]
Such a problem may be caused by using a solid material such as the arms 5a, 5b, 5c, and the body 4, or by giving a contrivance to the shapes of the arms 5a, 5b, 5c, and the arms 5a, 5b, 5c. Although this may be solved by devising the connection structure between each of the above and the body 4 or increasing the thickness of the arms 5a, 5b, 5c, it results in an increase in weight and cost.
[0007]
Furthermore, unlike the rotary door, the sliding door has an advantage that the door opening / closing space can be greatly reduced, but the sliding door opening / closing locus, that is, the shift amount to the side of the vehicle is reduced. Taking a large size causes a disadvantage that the advantages of the sliding door are impaired.
[0008]
In view of these points, the present invention provides an armrest device for a sliding door having sufficient strength, usability, and the like as compared with an armrest installed and configured on a rotary door without impairing the advantages of the sliding door. The purpose is to do.
[0009]
[Means for Solving the Problems]
The armrest device for a sliding door according to the present invention is attached to the indoor side of the sliding door, and is capable of rotating from a standing state to the sliding door from a standing state with respect to the sliding door, and an opening / closing operation of the sliding door An armrest rotation control unit that rotates the armrest in conjunction with the armrest. The armrest rotation control unit is rotatably attached to the slide door, and a drum that rotates the armrest is fixed to one end of the drum. The other end is fixed to the vehicle body side and is wound around the drum, and the opening of the slide door causes the wire wound around the drum to be pulled out of the drum. On the other hand, the wire drawn from the drum is moved by the closing operation of the slide door. Is wound in the ram, characterized in that the drum is reversed.
[0011]

[0012]
In the armrest device for a sliding door according to the present invention, it is preferable that a gear for transmitting the rotation of the drum to the support shaft of the armrest is interposed between the drum and the armrest.
[0013]
In the armrest device for a sliding door according to the present invention, preferably, a reaction force spring is wound around the support shaft, and one end of the reaction force spring is fixed to the second bracket so that the armrest is deployed. It is energized as follows.
[0014]
In the armrest device for a sliding door according to the present invention, it is preferable that the gear is a reduction gear that transmits the rotational force of the drum by reducing the rotational force to the support shaft.
[0015]
In the armrest device for a sliding door of the present invention, the drum preferably has an outer diameter on one side in the axial direction larger than an outer diameter on the other side .
[0016]
In the armrest device for a sliding door according to the present invention, preferably, a guide serving as a winding path for the wire is formed on the peripheral surface of the drum.
[0017]
According to the present invention, the armrest is movable so that its opening degree can be changed in conjunction with the opening / closing operation of the slide door, so that the armrest does not collide with the body due to the installation of the armrest. Thereby, there is no need to make the shift amount of the sliding door larger in the width direction W than the conventional sliding door, and the advantage as the sliding door is not impaired, so the merchantability of the sliding door is not impaired. . Further, by automatically interlocking the opening / closing operation of the slide door and the rotation of the armrest, a new burden of rotating the armrest by the user is not imposed. Furthermore, by automatically interlocking with the opening and closing of the sliding door, it becomes possible to prevent the armrest and the body from colliding with each other when the user forgets to rotate the armrest. It can also be prevented.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an armrest device for a sliding door according to the invention will be described with reference to the drawings.
FIG. 1 is a view showing a mode in which an armrest device 6 for a sliding door is attached to the sliding door 1, FIG. 2 is an enlarged view of a main part thereof, and FIG. 3 is a lower part of the sliding door 1 and a rocker portion 4a of a vehicle body. It is a partial expanded sectional view of the periphery.
The slide door 1 includes a door outer panel 7b, a door inner panel 7a, and a door trim 7c as a lining from the outdoor side toward the indoor side. As will be described later, a predetermined region of the door trim 7c is recessed to form an armrest storage portion S1 on the inner side of the slide door 1, and an obliquely lower front region of the armrest storage portion S1 is similarly recessed. Thus, a mechanism storage S2 is formed.
[0019]
The armrest device 6 for a sliding door includes an armrest 6a on which a user's elbow, arm, and the like are placed. The armrest 6a is attached to a predetermined portion inside the slide door 1, that is, the armrest storage portion S1. For example, between the arm fixing bracket 8 as the first bracket and the mounting bracket 9 as the second bracket, which are fixed to the inner panel 7a of the slide door 1 in the same horizontal position. It is pivotally mounted. Note that, when this shaft is attached, a single support shaft 10 may be passed through and supported by shaft holes 6b drilled on both front and rear sides of the armrest 6a. Alternatively, the shaft holes 6b drilled in the front and rear side surfaces may be supported by individual support shafts. The armrest 6a penetrates the support shaft 10, and when the support shaft 10 rotates, the armrest 6a also rotates in conjunction with it.
[0020]
Then, for example, the armrest rotation control unit 7 that drives the armrest 6a to rotate is disposed in the mechanism storage unit S2, which is a position obliquely below and forward of the armrest 6a. The drum 11 in the armrest rotation control unit 7 is interposed between a drum fixing bracket 12 as a third bracket fixed to the door inner panel 7a and a mounting bracket 9 which is also used as a shaft attachment of the armrest 6a. It is rotatably mounted on the shaft. The drum fixing bracket 12 is provided at a position facing the arm fixing bracket 8 with the mounting bracket 9 interposed therebetween.
[0021]
One end of the wire 13 wound around the drum 11 is fixed at the rear end of the drum 11, and the other end is fixed by a wire fixture 14 provided at a position described later. At that time, the wire 13 is guided to a position near the lower arm 16 through a wire path tube 15 having a through hole in the vertical direction below the contact point between the drum 11 and the wire 13. Then, the wire 13 is positioned in front of the wire path tube 15 in the fully closed state of the slide door 1 at the rocker portion 4a over the vicinity of the rotational movement path 18 of the roller 17 connected to the lower arm 16. It is fixed by a fixing tool 14 or the like. The wire fixture 14 includes a compression spring 19 as shown in FIG. 3, and the compression spring 19 is configured to absorb the slack of the wire 13.
[0022]
Here, as a gear for transmitting the rotational force of the drum 11 to the armrest 6a, as shown in FIG. 2, for example, a shaft is attached between the mounting bracket 9 and the drum 11, and the drum 11 and the rotation shaft are made the same. And a reduction gear constituted by a small gear 20 that engages with the small gear 20, and a large gear 21 that is coaxial with the armrest 6 a and is attached to the drum 11 side of the mounting bracket 9. The small gear 20 may be disposed at a position facing the drum 11 with the mounting bracket 9 interposed therebetween, and the large gear 21 may be disposed at a position interposed between the mounting bracket 9 and the armrest 6a. .
[0023]
A reaction force spring 22 is wound around the spindle 10. The number of turns may be one or more. One end of the reaction spring 22 is inserted between the armrest 6 a and the mounting bracket 9 and fixed to the mounting bracket 9. Thus, the armrest 6a is biased so as to be always deployed. Further, the urging force by the reaction force spring 22 is transmitted to the drum 11 through the reduction gear, and rotates the drum 11. Here, the drum 11 is set to take up the wire 13 by this rotation.
[0024]
Here, as an example of the state of attachment of the armrest device for slide door to the slide door 1, FIGS. 4 (a) and 4 (b) are cross-sectional views taken along the line XX of FIG. FIG.
As shown in FIG. 4 (a), the door inner panel 7a in the region serving as the armrest storage portion S1 is opened, and the door trim 7c is stretched through the opening from the vehicle interior side. That is, the armrest storage portion S1 is formed in the slide door 1 by the opening of the door inner panel 7a and the recess of the door trim 7c. Moreover, as shown in FIG.4 (b), the attachment bracket 9 is attached to the door inner panel 7a. A door trim 7c is formed so that the arm fixing bracket 8, the mounting bracket 9 and the drum fixing bracket 12 can be attached to the door inner panel 7a. For example, in order not to obstruct each attachment, for example, a hole for the attachment is opened.
[0025]
FIG. 5 is a side view of a preferred drum. The drum 11 is formed by changing the outer diameter in the axial direction. That is, in the case where the drum 11 is disposed via the reduction gear on the front F side of the armrest 6a, the drum 11 is formed to have a small outer diameter on the front F side and a large outer diameter on the rear R side. Further, a guide 23 serving as a winding path for the wire 13 is spirally formed on the peripheral surface of the drum 11 from the front end to the rear end of the drum 11.
[0026]
With the above configuration, as shown in FIGS. 6A and 6B, when the slide door 1 is in the fully closed state, the armrest 6a is in the unfolded state. That is, the armrest 6 a is in a state of standing with respect to the slide door 1. At this time, the wire 13 is wound around the drum 11. The opening angle of the armrest 6a is determined by the degree of contact with a door trim (not shown in FIG. 6) provided on the inner side of the door inner panel 7a, but is about 90 degrees.
[0027]
When the wire path pipe 15 starts moving from the front F to the rear R with respect to the vehicle by the opening operation of the slide door 1 by the user from the fully closed state, the wire 13 is moved from the drum 11 accordingly. When unwinding begins, the drum 11 begins to rotate forward in the direction of the arrow in FIG. The small gear 20 is rotated forward by the normal rotation of the drum 11, and the large gear 21 is rotated in the reverse direction by the reduction gear. The rotation of the large gear 21 causes the armrest 6a to start to be folded by starting to rotate in the direction of the arrow in FIG. In addition, since the diameter of the drum 11 is changed in the axial direction, the rotational speed of the armrest 6a is larger than that at the time when the folding is finished.
[0028]
Then, when the sliding door 1 is in the half open state, as shown in FIGS. 7A and 7B, the angle is larger than about 45 degrees (for example, about 60 degrees), and the opening degree of the armrest 6a is as follows. Even if it is large, the angle is less than 45 degrees (for example, around 30 degrees). This value is preferably as small as possible, but is determined according to the setting of the diameter of the drum 11 in the axial direction.
Thereafter, when the slide door 1 is fully opened, the armrest 6a is in a state of being laid down on the slide door 1 as shown in FIGS. That is, the opening angle of the armrest 6a is approximately zero degrees. This opening angle is also determined by the degree of contact with a door trim (not shown in FIG. 8) provided on the inner side of the door inner panel 7a.
[0029]
On the other hand, as shown in FIGS. 8A and 8B, the wire path pipe 15 moves from the rear R to the front F with respect to the vehicle by the closing operation of the slide door 1 by the user from the fully open state. When starting, the wire 13 starts to be wound around the drum 11 under the bias of the reaction force spring 22, and the drum 11 starts to reverse in the direction of the arrow in FIG. In response to the reverse rotation of the drum 11, the small gear 20 rotates reversely, causing the large gear 21 to rotate in the direction of the arrow in FIG. 8 via the reduction gear, whereby the armrest 6 a starts to be deployed. At this time, since the outer periphery of the drum 11 is changed in the axial direction, the rotation speed of the armrest 1 is lower than that at the end of the closing operation of the slide door 1. Then, after the half-open state (FIGS. 7A and 7B), when the rotational speed of the armrest 6a is increased and the slide door 1 is fully closed, the armrest 6a is in a state of being expanded to about 90 degrees. .
[0030]
As described above, the wire 13 is unwound or wound up from the drum 11 by the opening / closing operation of the slide door 1. As a result, the drum 11 rotates forward in the direction of the arrow in FIG. 6 or reverses in the direction of the arrow in FIG. By the forward / reverse rotation of the drum 11, the support shaft 10 of the armrest 6a is driven through the speed reduction gear, and the opening degree of the armless 6a is controlled. Therefore, the armrest 6a is folded by the opening operation of the sliding door 1, and the sliding door 1 can be completely opened without the armrest 6a colliding with the vehicle body.
[0031]
Since the drum 11 has a shape in which the diameter thereof is changed in the axial direction, for example, a shape that is large at the rear of the drum 11 and small at the front, the rotation speed of the armrest 6a is changed according to the open / close state of the slide door 1. As a result, the opening angle can be controlled. That is, immediately after the sliding door 1 starts to open from the fully closed state or immediately before closing, the rotation speed of the armrest 6a is increased, and conversely, immediately after the sliding door 1 starts to close from the fully open state or before fully opening. In this case, it is possible to prevent the armrest 6a and the body 4 from colliding as much as possible by reducing the rotation speed of the armrest 6a.
[0032]
The specification of the drum 11 is determined in accordance with the shape and size of the armrest 6a as well as the illustrated one, and in accordance with the change in the rotational speed of the armrest 6a.
[0033]
As mentioned above, although embodiment of this invention was described based on drawing, this invention is not limited only to this embodiment, In the range of this invention, it can change suitably.
For example, the shape of the armrest, the manner of attachment to the slide door, and the form of rotational drive from the drum to the armrest are not limited to those described above, and can be variously employed and obtain the same effects as the above-described embodiment. Can do.
In addition, by interposing a reduction gear, the shape of the drum can be reduced.
Furthermore, even when the armrest storage unit or mechanism storage unit is not on the slide door, the armrest and the armrest rotation control unit are provided on the inner surface of the slide door so that the drum rotates as the slide door opens. Since the rotation is transmitted to the support shaft of the armrest and the armrest falls on the slide door, the armrest can be rotated in conjunction with the opening and closing of the slide door.
[0034]
【The invention's effect】
As described above, according to the present invention, the armrest is automatically rotated in conjunction with the opening / closing operation of the slide door so that the opening angle can be controlled. Thereby, a collision with an armrest and a body can be prevented beforehand, and an armrest can be set to a slide door as a result. In addition, since the advantage of the sliding door that the sliding door can be opened and closed in a small space can be sufficiently maintained, the commercial value of the sliding door can be increased. In addition, the wire winding system using a drum is used as an interlocking mode with the sliding door opening and closing operation. By adjusting the shape of the drum in the axial direction, the rotation speed of the armrest can be freely changed, and the specification can be easily changed. It has excellent advantages such as being.
