Abstract

PURPOSE:To prevent an outward appearance from being detracted even if a large load is applied to an arm-rest, and to eliminate a fear that a cover is damaged when a load is applied to the cover, by a method wherein the rubber end of the cover which hides a recess for storing the arm-rest is connected to the upper part of bottom of the recess, and the lower end of the cover is connected to the lower part of the arm-rest, and as the arm-rest is inclined forward from the stored position thereof, the title device is formed so that the arm-rest pushes a plate member forward. CONSTITUTION:When an arm-rest 4 is inclined forward, an arm 18 is turned counterclockwise and stood, and as the arm-rest is inclined forward, the arm 18 pushes a plate member 15 forward. Since a link plate 23 turns an arm 20 counterclockwise as a bracket 7 rotates counterclockwise, a lever 22 fixed to an upper arm part 20a on the arm 20 pushes forward a plate member 14 at the intermediate plate of a cover 10, and a plate member 13 rotates clockwise around a pin 17. In the state in which the arm-rest 4 is inclined on a seat- cushion 1, the plate member 14 at the intermediate place of the cover 10 is extended so as to be almost parallel to the front of the seat-back 2, and hides a recess 5 formed when the arm-rest 4 is used.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an armrest device provided in a seat hack of a vehicle seat.

(Prior Art) Conventionally, an armrest device is known that is stored in the seat back of a rear seat of an automobile when not in use, and is tilted forward when in use (see Japanese Utility Model Publication No. 62102449).

FIG. 4 shows a rear seat for an automobile equipped with such an armrest device, and is composed of a seat cushion 1 and a seat back 2. A vertically long rectangular armrest storage recess 5 is formed in the seat back 2, and an armrest 4 rotatably supported in the lower part of the recess 5 is stored in this recess 5. When in use, this armrest 4 is is tilted forward and laid down on the seat cushion 1.

By the way, in a car seat equipped with such an armrest 4, the armrest storage recess 5 remains open at the front of the seat back 2 during use, spoiling the appearance of the seat. It has been proposed that a cover made of a single plate member is connected to the base of the armrest 4 to cover the opening of the recess 5 as the armrest 4 is tilted forward from the storage position.

However, in a configuration in which such a cover is connected to the base of the armrest 4, a large load is applied downward to the front end of the armrest 4 that is tilted on the seat cushion 1 during use. If the front end of the armrest 4 sinks, the armrest storage recess 5
There was a risk that the cover covering the seat would protrude further forward than the front of the seat back 2 as the armrest 4 moved. As a result, the aesthetic appearance of the seat back is significantly impaired, and there is also the problem that small objects may fall into the four parts 5 through the gap created between the cover and the seat back 2. Furthermore, when a large load is applied to the cover itself, there is a problem in that the connecting portion between the armrest 4 and the cover is damaged.

(Purpose of the Invention) Therefore, the present invention aims to prevent damage to the cover even when a large load is applied to the armrest when the armrest is tilted to the use position, and to prevent the cover from being damaged even when a load is applied to the cover. The aim is to provide an armrest device that does not require any armrest.

(Structure of the Invention) In the armrest device of the present invention, a cover is provided on the bottom side of the armrest storage recess formed in the seat back, and is made up of a plurality of plate members connected vertically in order so as to be bendable at the connecting portion. The upper end of the cover is connected to the upper bottom of the armrest storage recess, and the lower end is connected to the base of the armrest, and as the armrest is tilted forward from the storage position, the cover is pushed forward and the opening of the armrest storage recess is connected. It was meant to be covered.

In the armrest device of the present invention, in order to ensure that the cover is pushed forward as the armrest is tilted forward from the storage position of the armrest, Means is provided for pressing the plate member forward when the plate member is tilted.

Further, in the invention described in claim 2, when the armrest is in the storage position, the position of the connecting portion of the predetermined two plate members of the cover is changed as the armrest is tilted forward from the storage position. It is set in a position where it receives a force that causes the part to be pushed forward.

(Effects of the Invention) According to the present invention, the cover that covers the armrest storage recess when the armrest is used is composed of a plurality of bendably connected plate members, and the upper end of the cover is attached to the upper part of the bottom of the recess. Since the lower end is connected to the lower part of the armrest, the cover can be automatically deployed into the opening of the recess when the armrest is tilted forward from the storage position, and the lower end is connected to the lower part of the armrest. Even if a load of

Further, according to the present invention, since the plate member is configured to be pushed forward as the armrest is tilted forward from the storage position, the plate member is pushed forward as the armrest is tilted forward. The upward force prevents a tension phenomenon between this plate member and the plate member above it, or prevents the upper plate member from pivoting backwards, allowing smooth deployment of the cover. operation becomes possible.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

1 and 2 are vertical cross-sectional views showing a first embodiment of the armrest device according to the present invention.・Shows the state in which the device is tilted on the position 1. In FIG. 1, a seat cushion 1 is fixed on the floor of a vehicle body, and a seat back 2 is fixed to a rear panel 3 of the vehicle body. A vertically long rectangular armrest storage recess 5 is open in the seat back 3, and the armrest 4 is stored in the recess 5.

The armrest 4 includes a frame 6 therein, and brackets 7 are fixed to the left and right lower ends of the frame 6, respectively. A pair of left and right support brackets 8 are provided on the vehicle body rear panel 3 to protrude forward, and a bracket 7 is rotatably supported at the front ends of these support brackets 8 by a shaft 9 whose axis direction is in the vehicle width direction. By rotating together with the armrest 4, the armrest 4 can take a position where it is stored in the recess 5 of the seat back 2 and a position where it is tilted on the seat cushion 1 (usage position). It is composed of

The bottom of the armrest storage recess 5 is attached to the vehicle body panel 3.
When the armrest 4 is housed in the recess 5, a predetermined gap 5a is formed between the back surface of the armrest 4 and the front surface 3a of the vehicle body rear panel 3. A cover 10 for covering the front surface of the four armrest storage parts 5 when the armrest 4 is tilted onto the seat cushion 1 is stored in the gap 5a along the front surface of the vehicle body rear panel 3.

The cover 10 has two pins 11 and 12 extending in the vehicle width direction.
It is composed of three plate members 13, 14, and 15 that are sequentially connected by the pins 11, 12, and bendable at the positions of the pins 11, 12, and the upper end of the uppermost plate member 13 is provided on the front surface 3a of the vehicle rear panel 3. It is rotatably supported by a pair of left and right brackets 16 via a shaft 17. The axial directions of the shaft 17 and pins 11 and 12 are both in the vehicle width direction. Further, the lower end of the lowest plate member 15 is fixed to the tip of an arm 18 that rotates together with the armrest 4 by having its base fixed to a bracket 7 provided at the base (rotation shaft) of the frame 6 of the armrest 4. .

Furthermore, a bracket 19 is provided on the front surface of the vehicle body rear panel 3 in a protruding manner above the mounting position of one of the support brackets 8 of the armrest 4, and at the tip of this bracket 19,
Two arm parts 20a.

An arm 20 having an arm 20b is rotatably attached to a shaft 21 having an axial direction in the vehicle width direction. At the tip of the upper arm part 20a, a plate member extending from the arm part 20a, extending rearward and upward, and then passing through the gap 3a along the back surface of the intermediate plate member 4 (front side of the vehicle rear panel 3) of the cover 10 is provided. Cover extrusion bar 22 extending in the width direction
is fixed. The tip of the lower arm portion 20b,
Elongated link plates 23 are connected between the armrest 4 and the bracket 7 provided at the base of the frame 6 via shafts 24, 25, respectively.

In the above configuration, when the armrest 4 is tilted forward about the axis 9 from the state shown in FIG. 1, the arm 18 whose base is fixed to the bracket 7, which rotates together with the armrest 4, rotates counterclockwise. and stand up. Along with this,
This arm 18 pulls out the lowermost plate member 15 of the cover 10 attached to its tip forward and upward.

Further, as the bracket 7 rotates counterclockwise, the link plate 23 whose one end is pivotally supported by the bracket 7 rotates the arm 2o counterclockwise, so that the upper arm portion of the arm 20 Bar 2 fixed to 20a
2 pushes the intermediate plate member 14 of the cover 10 forward, and accordingly, the uppermost plate member 13 of the cover 10 rotates clockwise around the shaft 17, and the armrest 4 moves onto the seat cushion 1. In the tilted state, as shown in FIG. 2, the middle plate member 1 of the cover 10
At a position where the armrest 4 slightly enters the recess 5 from the front surface of the seat back 2, it is unfolded so as to be substantially parallel to the front surface of the seat back 2, and covers the recess 5 when the armrest 4 is in use.

The above explanation has clarified the configuration and operation of the armrest device according to the present invention, but in this example,
The upper end of the uppermost plate member 13 of the cover 10 is the shaft 17
The lowermost plate member 15 of the cover 10 is connected to the base of the armrest 4, and the intermediate plate member 14 between the two plate members 13.15 is supported by a pin 11.12 on the upper part of the bottom surface of the recess 5. Since the armrest 4 is connected in a bendable manner at the 11 and 12 positions,
Even if an unnecessary load is applied, there is no fear that the cover 10 will change its position significantly, and even if a load is applied to the cover 10, there is no fear that the cover 10 will be damaged.

Furthermore, this embodiment includes a bar 22 that operates to push the back surface of the plate member 14 of the cover 10 forward in accordance with the tilting movement of the armrest 4 when the armrest 4 is tilted onto the seat cushion 1. Therefore, there is no fear that a dead point will occur at the position of the plate member 13.14 or the pin 11 and a tension phenomenon will occur due to the upward force applied to the plate member 14 when the armrest 4 is tilted. This also prevents the cover 10 from rotating counterclockwise from the dead point, allowing the cover 10 to unfold smoothly.

Next, FIG. 3 is a longitudinal sectional view showing a second embodiment of the present invention.

This embodiment has a configuration similar to that of the first embodiment of the present invention described above, so common members are given the same reference numerals and redundant explanations are omitted.
The cover 1 is not equipped with the arm 20, the bar 22, the link plate 23, etc. that were included in the embodiment, and instead the armrest 4 is housed in the recess 5.
0 top plate member 13 and this plate member 1
By setting the position of the connecting portion with the intermediate plate member 14 which is bendably connected to the lower part of the armrest 4 by the pin 11, when the armrest 4 is tilted forward from its storage position, the force applied to the intermediate plate member 14 is set. The plate members 13, 14 are prevented from being stretched by an upward force, or the uppermost plate member 13 is prevented from rotating in the opposite direction (counterclockwise). It is.

That is, the shaft 17 that pivotally supports the uppermost plate member 13 of the cover 10 is provided in contact with the vehicle body rear panel 3,
The tip of a bracket 30 protruding rearward and downward from the upper end of the plate member 13 is pivotally supported by a shaft 17. As a result, the position of the pin 11 that connects the plate members 13, 14 when the armrest is stored is located forward of a plane P that includes the shaft 17 and the pin 12 and is perpendicular to the plane of the drawing. Therefore, when the plate member 14 receives an upward force as the armrest 4 is tilted forward from its storage position, the force causes the plate member 13 to rotate forward (clockwise) about the shaft 17. Since it acts to move the cover 10, it is possible to smoothly unfold the cover 10 without using the aforementioned operation bar 22 or the like.
