Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an armrest device used for a seat having a backrest.

[Prior Art] A seat having a seat portion and a backrest, such as a rear seat of an automobile, is known in which an armrest is provided so that a seated person can rest his elbow. It is desirable that the armrest be stored on the backrest side so as not to get in the way when not in use. For this reason, an armrest device is also known in which an opening is provided in the backrest and an armrest can be stored in the opening.

In this type of armrest device, in order to make it possible to hide the opening when using the armrest, a movable board that protrudes to the front of the opening in conjunction with the rotation operation of the armrest is provided inside the opening. The one provided is being developed.

For example, the conventional armrest device 1 shown in FIG.
Inside the opening 3 provided in the backrest 2, a movable board 5 that interlocks with the armrest 4 is provided. The upper portion of the board 5 is slidably supported in the vertical direction by the supporting portion 6, and when the armrest 4 is rotated in the direction of arrow A, the lower portion of the board 5 is projected forward. .

[Problems to be Solved by the Invention] The conventional device 1 has a simple structure, but the upper portion of the board 5 does not protrude forward, so that the opening 3 cannot be sufficiently closed.

A structure different from that of the above-mentioned conventional device 1 and capable of pushing the entire board forward by using a link mechanism or the like has been considered, but this requires a complicated link mechanism and The size of the direction is large, and it is difficult to install it in the backrest.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an armrest device which has a simple structure and which allows the entire board to be pushed out forward and has a small front-rear dimension.

[Means for Solving the Problems] The present invention developed to achieve the above object includes a backrest, an opening provided in the backrest and having at least a front side opening, and a position to be stored in the opening. First in the horizontal direction across the position where it is pulled out from this opening
An armrest attached so as to be rotatable around the axis of
A first connecting end that is provided at the rear of the armrest and rotates integrally with the armrest about the first axis, and a second axis that is provided at an upper portion inside the opening section in the front-back direction. A swinging member, which is swingably supported and has a second connecting end at a lower portion, and a swing board provided inside the opening extending over the first connecting end and the second connecting end. ing. The swingboard has the second swingboard when the armrest is in the retracted position.
Is arranged so that the connection end of is located on the front side of the line segment connecting the second shaft and the first connection end.

[Operation] The armrest of the present invention is stored in the opening of the backrest when not in use. The armrest in the retracted state functions as part of the backrest. When the armrest is rotated in the direction of being pulled out from the opening for use, the lower part of the swingboard is pushed up by the first connecting end and the upper part of the swingboard and the rotating member are pushed at the initial stage of the rotation. The connecting part bends in a V shape and moves forward. In other words, the upper part of the swingboard is ahead and the swingboard is forward. As the armrest approaches the turning end (use position), the lower side of the swingboard also moves forward, and eventually the entire swingboard protrudes forward in the opening.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The armrest device 10 shown in FIG. 1 is provided on a backrest 11 of a rear seat of an automobile. On the back surface 11a side of the backrest 11, there is a standing wall 12 which is a part of the vehicle body.

An opening 13 is provided in the widthwise intermediate portion of the backrest 11, and an armrest 15 is stored in the opening 13. The opening 13 is formed in a shape and size corresponding to the armrest 15 so that the armrest 15 can be just fitted therein. The opening 13 in the illustrated example is open on both front and rear surfaces and the lower surface side of the backrest 11, but in some cases, only the front surface side may be opened.

The backrest 11 includes a seat back frame (not shown), an elastic pad 16 that covers the seat back frame, and the like. A well-known seat portion 20 is provided below the backrest 11. The seat portion 20 includes a cushion frame (not shown), an elastic pad 21, and the like.

The armrest 15 is rotatable about a horizontal first shaft 25 provided in a lower portion inside the opening 13 from a storage position shown in FIG. 1 to a use position shown in FIG. It is provided. The turning operation angle θ ₁ is, for example, about 105 °. The first shaft 25 is provided on a bracket 26, which is fixed to the frame on the backrest 11 side. Armrest 15 is a frame
27, an elastic pad 28 and the like.

A hinge bracket 30 is provided on the base end side of the frame 27, that is, near the base of the armrest 15. The hinge bracket 30 has the armrest 15 centered around the first axis 25.
And rotate together. The hinge bracket 30 is provided with a first connecting end 31. When the armrest 15 is in the retracted position shown in FIG. 1, the first connecting end 31 is
It projects obliquely upward from the rear end of the hinge bracket 30. Therefore, the connecting end 31 also rotates integrally with the armrest 15 about the first shaft 25.

A second horizontal shaft 35 is provided on the upper inner side of the opening 13. The second shaft 35 is located in the vicinity of the back surface 11a of the backrest 11 and is provided on the frame on the backrest 11 side. A rotating member 37 is pivotally attached to the second shaft 35 so as to be swingable in the front-rear direction. The rotating member 37 has an arm portion 38 that protrudes forward of the second shaft 35 when the armrest 15 is in the storage position shown in FIG. A second connecting end 39 is provided at the lower end of the rotating member 37.

A swing board 41 is provided across the first connection end 31 and the second connection end 39. The lower end of the swing board 41 is rotatably connected to the first connection end 31 about a horizontal axis, and the upper end of the swing board 41 is rotated about the horizontal axis to the second connection end 39. It is movably connected.

As the material of the swing board 41, for example, a relatively hard synthetic resin panel is adopted so that it can exhibit a certain degree of rigidity against a compressive load applied in the longitudinal direction. The swing board 41 is made wide and shaped so as to close the opening 13. If necessary, a surface material such as cloth or leather may be attached to the surface side of the swing board 41 so as to be unified with the material of the backrest 11. Instead of the resin panel, the swing board 41 may be a rigid frame member to which a screen body such as cloth or leather is stretched.

As shown in FIG. 1, the second connecting end 39 is located ahead of the line segment M connecting the second width 35 and the first connecting end 31 when the armrest 15 is in the retracted position. There is. That is, the swing board 41 or the rotating member 37 is supported from the back side by an appropriate means so that the second connecting end 39 does not descend rearward from the above position. The rotating member 37 and the swing board 41 form a link system.

Next, the operation of the armrest device 10 having the above structure will be described.

When the armrest 15 is not used, the armrest 15 is stored in the opening 13 as shown in FIG. In this retracted state, the swing board 41 is located on the back side of the armrest 15 so as to substantially overlap in the thickness direction. Further, the rotating member 37 extends above the swing board 41 and generally on an extension line. Therefore, the armrest 15, the swing board 41, and the rotating member 37 in the retracted position are compact without being bulky in the thickness direction of the backrest 11.

When using the armrest 15, use the armrest 15 with your hand.
Through the opening 13. By doing so, the armrest 15 rotates counterclockwise in the drawing around the first shaft 25,
The intermediate state shown in FIG. 2 leads to the use state shown in FIG.

When the armrest 15 rotates in the above direction, the hinge bracket 30 and the first connecting end 31 also rotate counterclockwise about the first shaft 25.

As described above, when the armrest 15 is pulled out from the retracted position to the front, in the initial stage of rotation of the armrest 15, the first
Since the connection end 31 of is mainly moved upward, this movement is transmitted in the direction of pushing up the swing board 41, and
37 starts to move clockwise around the second axis 35 as shown. The second connecting end 39 mainly moves forward in the initial stage of rotation of the armrest 15.

When the armrest 15 is in the retracted position, the second connecting end 39 is located in front of the line segment M connecting the second shaft 35 and the first connecting end 31, so that the armrest 15 is in the retracted position. When the first connecting end 31 is pushed upward when being pulled out in the use direction, the behavior is such that the upper end side of the swing board 41 always moves forward. Ie swing board 41
The connecting portion between the rotating member 37 and the swing board 41 can move forward while bending in a dogleg shape without causing an erroneous operation such as falling backward.

As shown in FIG. 3, when the armrest 15 is rotated to a position where it comes into contact with the seat surface, the first connecting end 31 moves to almost the frontmost portion, and the second connecting end 39 is also roughly. It moves to the front. Therefore, the entire swing board 41 protrudes to the vicinity of the front surface of the opening 13 and closes the opening 13.

As shown in FIG. 4, when the armrest 15 is lowered from its normal position due to the downward load P applied, the swing board 41 and the rotating member 37 are slightly displaced in the direction of the arrow F in the drawing, There is no fear that an excessive load will occur on the link system such as the member 37 and the swing board 41.

When the armrest 15 is stored, the armrest 15 is pushed clockwise into the opening 13 to push the armrest 15 into the opening 13. In this case, the swing board 41 and the rotating member 37 move in the direction opposite to that in the above-described withdrawal state, so that the retracted state of FIG. 1 is restored.

[Advantage of Invention] According to the present invention, when the armrest is used, the entire swingboard can be pushed up to the vicinity of the front of the opening, and the opening is closed to improve the appearance. The link system composed of a swing board, a rotating member, etc., which has been used, can be constructed thinly, has a simple structure, and is free from malfunction.
