Description
この発明は、インストルメントパネル構造およびインストルメントパネルの加工方法に関するものである。 The present invention relates to an instrument panel structure and an instrument panel processing method.
自動車などの車両には、車室内の前部にインストルメントパネルが設置されている。 In vehicles such as automobiles, an instrument panel is installed in the front part of the passenger compartment.
このインストルメントパネルの助手席側の部分には、助手席乗員用のエアバッグ装置が設けられている（例えば、特許文献１参照）。 An airbag device for a passenger on the passenger seat is provided on the passenger seat side of the instrument panel (see, for example, Patent Document 1).
このエアバッグ装置は、裏面側に、開裂溝によって開口予定部となるリッド部が形成されたインストルメントパネルと、このインストルメントパネルの下方に、上記リッド部へ向けて配設されたエアバッグモジュールと、このエアバッグモジュールと上記インストルメントパネルとの間に介在されて、上記エアバッグモジュールから膨出された袋状のエアバッグ本体を上記リッド部へ案内するガイド部材と、を備えたものとされる。 The airbag device includes an instrument panel in which a lid portion to be opened by a cleavage groove is formed on the back surface side, and an airbag module disposed below the instrument panel toward the lid portion. And a guide member that is interposed between the airbag module and the instrument panel and guides the bag-shaped airbag body inflated from the airbag module to the lid portion. Is done.
そして、上記したインストルメントパネルの裏面側には、上記開裂溝を形成するための開裂溝形成予定部と、上記ガイド部材を振動溶着によって固定するための溶着固定部と、が設けられる。更に、上記したインストルメントパネルの裏面側には、上記溶着固定部の周辺に、上記ガイド部材を位置決めするための位置規制用リブが設けられる。 Then, on the back side of the instrument panel described above, a cleavage groove formation scheduled portion for forming the cleavage groove and a welding fixing portion for fixing the guide member by vibration welding are provided. Furthermore, a position regulating rib for positioning the guide member is provided on the back side of the instrument panel in the vicinity of the welding fixing portion.
しかしながら、上記インストルメントパネル構造には、以下のような問題があった。
即ち、上記した位置規制用リブは、インストルメントパネルの製造と同時に形成されるものであるのに対し、上記したガイド部材は、インストルメントパネルに開裂溝を形成した後にインストルメントパネルに対して取付けられるものであった。そのため、位置規制用リブの位置を事前に設定する際には、インストルメントパネルに対する開裂溝の形成位置のばらつきと、開裂溝に対するガイド部材の取付位置のばらつきとを考慮しなければならず（或いは、上記ばらつきを考慮して寸法公差を大き目に設定しなければならず）、位置規制用リブは、ガイド部材に対する位置決め精度の低いものとなっていた。
However, the instrument panel structure has the following problems.
That is, the above-described position regulating rib is formed at the same time as the manufacture of the instrument panel, whereas the above-described guide member is attached to the instrument panel after forming the cleavage groove in the instrument panel. It was Therefore, when setting the position of the position regulating rib in advance, it is necessary to consider the variation in the formation position of the cleavage groove with respect to the instrument panel and the variation in the attachment position of the guide member with respect to the cleavage groove (or In view of the above variation, the dimensional tolerance must be set large), and the position regulating rib has low positioning accuracy with respect to the guide member.
しかし、インストルメントパネルに対するガイド部材の取付位置精度や、ガイド部材と開裂溝との間の位置精度などは、エアバッグ装置の展開性能に影響するため、上記した位置精度をより向上させたいという要求があった。 However, since the mounting position accuracy of the guide member with respect to the instrument panel and the positional accuracy between the guide member and the tear groove affect the deployment performance of the airbag device, there is a demand for further improving the above-described position accuracy. was there.
そこで、本発明は、上記した問題点を解決し、開裂溝に対するガイド部材の取付け位置精度を向上し得るようにすることを、主な目的としている。 Therefore, the main object of the present invention is to solve the above-described problems and to improve the accuracy of the mounting position of the guide member with respect to the cleavage groove.
上記課題を解決するために、本発明は、
インストルメントパネルの裏面側に、
開口予定部となるリッド部を画成する開裂溝を形成するための開裂溝形成予定部と、
前記リッド部へ向けて袋状のエアバッグ本体を案内可能なガイド部材を振動溶着によって固定するための溶着予定部と、が設けられると共に、
該溶着予定部の周辺に、前記ガイド部材を位置決めするための位置規制用リブが設けられたインストルメントパネル構造において、
前記位置規制用リブが、前記開裂溝とガイド部材の取付位置との間に生じる位置のばらつき量よりも大きい削除可能代を有することを特徴とする。
In order to solve the above problems, the present invention provides:
On the back side of the instrument panel,
A cleavage groove formation planned portion for forming a cleavage groove that defines a lid portion to be the opening planned portion;
A welding planned portion for fixing a guide member capable of guiding the bag-shaped airbag body toward the lid portion by vibration welding; and
In the instrument panel structure provided with a position restricting rib for positioning the guide member around the welding planned portion,
The position regulating rib has a deletion allowance larger than a variation amount of a position generated between the cleavage groove and a mounting position of the guide member.
本発明によれば、上記構成によって、以下のような作用効果を得ることができる。
即ち、位置規制用リブが、削除可能代を備えるようにした。これにより、開裂溝の加工形成後に、開裂溝の実際の形成位置に合わせて、位置規制用リブの削除可能代を加工し、不要な部分を削除することにより、位置規制用リブが正確なものとなるので、位置規制用リブによってガイド部材を高精度に位置決めしてインストルメントパネルに溶着固定することが可能となる。
According to the present invention, the following effects can be obtained by the above-described configuration.
That is, the position restricting rib has a deletable allowance. As a result, after machining and forming the cleavage groove, the position restriction rib can be accurately obtained by processing the possible removal of the position restriction rib in accordance with the actual formation position of the cleavage groove and deleting unnecessary portions. Therefore, the guide member can be positioned with high accuracy by the position regulating rib and can be welded and fixed to the instrument panel.
以下、本実施の形態を、図面を用いて詳細に説明する。
図１〜図８は、この実施の形態を説明するためのものである。
Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 8 are for explaining this embodiment.
＜構成＞以下、この実施例の構成について説明する。
自動車などの車両には、車室内の前部に、図１の全体斜視図に示すような、インストルメントパネル１が設置されている。このインストルメントパネル１の助手席側の部分に、助手席乗員用のエアバッグ装置２を設ける。
<Configuration> The configuration of this embodiment will be described below.
In a vehicle such as an automobile, an instrument panel 1 as shown in the overall perspective view of FIG. An airbag device 2 for a passenger on the passenger seat is provided on the passenger seat side of the instrument panel 1.
このエアバッグ装置２は、図２の縦断面図に示すように、インストルメントパネル１の裏面側に形成された、開口予定部となるリッド部３と、このインストルメントパネル１の下方に、上記リッド部３へ向けて配設されたエアバッグモジュール５と、このエアバッグモジュール５と上記インストルメントパネル１との間に介在されて、上記エアバッグモジュール５から膨出された袋状のエアバッグ本体（図示せず）を上記リッド部３へ案内するガイド部材６と、を備えたものとされる。 As shown in the longitudinal sectional view of FIG. 2, the airbag device 2 is formed on the back side of the instrument panel 1, the lid portion 3 serving as a planned opening portion, and below the instrument panel 1, An airbag module 5 disposed toward the lid portion 3, and a bag-like airbag that is interposed between the airbag module 5 and the instrument panel 1 and bulges from the airbag module 5. A guide member 6 for guiding a main body (not shown) to the lid portion 3 is provided.
ここで、インストルメントパネル１およびガイド部材６は、樹脂製のものとされる。上記したリッド部３は、開裂溝４によって画成される。ガイド部材６は、エアバッグモジュール５の上部を取り囲んだ状態で、リッド部３の周縁部まで延びる取付脚部１１を有するものとされる。この取付脚部１１には、エアバッグモジュール５の上部に形成されたフック部５ａを係止可能な係止孔１１ａが設けられる。ガイド部材６は、この取付脚部１１の上端外周部分に一体に設けられて、インストルメントパネル１裏面におけるリッド部３よりも外側の部分に固定可能な取付基部１４と、リッド部３の裏面側に固定可能な補強ドア部１５と、この補強ドア部１５と取付脚部１１の上端内周部分との間を連結する下方迂回形状をしたヒンジ部１６と、を備えている。また、取付基部１４および補強ドア部１５の上面には、インストルメントパネル１の裏面側に溶着固定可能な溶着リブ１７が多数形成されている。 Here, the instrument panel 1 and the guide member 6 are made of resin. The lid portion 3 described above is defined by the cleavage groove 4. The guide member 6 includes mounting legs 11 that extend to the peripheral edge of the lid portion 3 in a state of surrounding the upper portion of the airbag module 5. The mounting leg portion 11 is provided with a locking hole 11a that can lock the hook portion 5a formed on the upper portion of the airbag module 5. The guide member 6 is integrally provided on the outer periphery of the upper end of the mounting leg 11, and can be fixed to a portion outside the lid portion 3 on the back surface of the instrument panel 1, and the back surface side of the lid portion 3. And a hinge portion 16 having a downward detour shape connecting the reinforcement door portion 15 and the inner peripheral portion of the upper end of the mounting leg portion 11. A large number of welding ribs 17 that can be welded and fixed to the back side of the instrument panel 1 are formed on the top surfaces of the mounting base portion 14 and the reinforcing door portion 15.
そして、図３に示すようなインストルメントパネル１の裏面側には、図４に示すように、上記開裂溝４を形成するための部位となる開裂溝形成予定部２１と、上記ガイド部材６を振動溶着によって固定するための部位となる溶着予定部２２と、が設けられる。更に、上記したインストルメントパネル１の裏面側には、上記溶着予定部２２の周辺に、上記ガイド部材６を位置決めするための位置規制用リブ２３が設けられる。 Then, on the back side of the instrument panel 1 as shown in FIG. 3, as shown in FIG. 4, a cleavage groove formation scheduled portion 21 that becomes a part for forming the cleavage groove 4 and the guide member 6 are provided. A planned welding portion 22 is provided as a part for fixing by vibration welding. Further, on the back surface side of the instrument panel 1 described above, a position regulating rib 23 for positioning the guide member 6 is provided around the planned welding portion 22.
なお、例えば、図５には、インストルメントパネル１の開裂溝形成予定部２１に対する開裂溝４の形成位置のばらつき量２５が、おおまかに示されている。そして、インストルメントパネル１に対する上記した位置規制用リブ２３の設置位置２６は、この開裂溝４の形成位置のばらつき量２５などによって影響を受けることとなる。 For example, FIG. 5 roughly shows the variation amount 25 of the formation position of the cleavage groove 4 with respect to the cleavage groove formation scheduled portion 21 of the instrument panel 1. The installation position 26 of the above-described position regulating rib 23 with respect to the instrument panel 1 is influenced by the variation amount 25 of the formation position of the cleavage groove 4 and the like.
そして、以上のような基本的な構成に対し、この実施例では、以下のような構成を備えるようにしている。 In this embodiment, the following configuration is provided for the basic configuration described above.
（１）図６（または図７）に示すように、上記位置規制用リブ２３が、上記開裂溝４とガイド部材６の取付位置との間に生じる位置のばらつき量（図示せず）よりも大きい削除可能代３１を有するものとされる。 (1) As shown in FIG. 6 (or FIG. 7), the position regulating rib 23 is more than the amount of variation in position (not shown) between the cleavage groove 4 and the mounting position of the guide member 6. It is assumed that it has a large deletable allowance 31.
ここで、開裂溝４とガイド部材６の取付位置との間に生じる位置のばらつき量には、上記したインストルメントパネル１に対する開裂溝４の形成位置のばらつき量２５や、インストルメントパネル１に対する位置規制用リブ２３の設置位置２６のばらつき量などが考慮される。 Here, the variation amount of the position generated between the cleavage groove 4 and the mounting position of the guide member 6 includes the variation amount 25 of the formation position of the cleavage groove 4 with respect to the instrument panel 1 and the position with respect to the instrument panel 1. A variation amount of the installation position 26 of the restriction rib 23 is taken into consideration.
（２）そして、上記位置規制用リブ２３が、前後規制リブ３５と左右規制リブ３６とを有するものとされる。そして、前後規制リブ３５が、車両前後方向の両側に設けられるようにする。 (2) The position regulating rib 23 includes a front / rear regulating rib 35 and a left / right regulating rib 36. The front / rear restricting ribs 35 are provided on both sides in the vehicle front-rear direction.
ここで、前後規制リブ３５は、通常の場合、型抜きの関係で、片側（例えば、車両後方側）にしか設けることができないものである。これは、車両前方側では、型抜き勾配を付けることによって、不必要に長いものになってしまうため、位置規制に使用できない形状にしかならないことによる。しかし、この実施例では、上記した型抜き勾配の部分を削除可能代３１として削除することによって、車両前後方向の両側（即ち、前後両方）に対して前後規制リブ３５を設けることが可能となる。なお、前後規制リブ３５は、車両前後方向へ延びるものとされ、この前後規制リブ３５に対し、削除可能代３１は、溶着予定部２２の内側に向いた端部に、長手方向の延長部として形成される。 Here, the front and rear restricting ribs 35 can be provided only on one side (for example, the rear side of the vehicle) because of die cutting in a normal case. This is because the front side of the vehicle is unnecessarily long due to the die-cutting slope, and thus has a shape that cannot be used for position regulation. However, in this embodiment, by deleting the above-described die-cutting slope portion as the erasable allowance 31, it becomes possible to provide the front and rear regulating ribs 35 on both sides in the vehicle longitudinal direction (that is, both front and rear). . The front / rear restricting rib 35 extends in the vehicle front / rear direction, and with respect to the front / rear restricting rib 35, the erasable allowance 31 is provided as an extension in the longitudinal direction at the end facing the inside of the planned welding portion 22. It is formed.
一方、左右規制リブ３６については、車幅方向に沿った左右の位置に設けることができる。左右規制リブ３６は、車両前後方向へ延びるものとされ、この左右規制リブ３６に対し、削除可能代３１は、溶着予定部２２の内側に向いた面に増肉部として形成される。 On the other hand, the left and right regulating ribs 36 can be provided at left and right positions along the vehicle width direction. The left and right restricting ribs 36 extend in the vehicle front-rear direction, and with respect to the left and right restricting ribs 36, the erasable allowance 31 is formed as a thickened portion on the surface facing the inside of the planned welding portion 22.
（３）上記したインストルメントパネル１は、以下のようにして、加工形成される。
図８に示すように、先ず、裏面側に、開口予定部となるリッド部３を画成する開裂溝４を形成するための開裂溝形成予定部２１と、上記リッド部３へ向けて袋状のエアバッグ本体を案内可能なガイド部材６を振動溶着によって固定するための溶着予定部２２と、この溶着予定部２２の周辺に、上記ガイド部材６を位置決めするための位置規制用リブ２３と、を有するインストルメントパネル１を成形する成形工程５１を行う。
次に、上記インストルメントパネル１の上記開裂溝形成予定部２１に上記開裂溝４を加工形成する開裂溝形成工程５２を行う。
そして、上記開裂溝４が形成された上記インストルメントパネル１裏面の上記溶着予定部２２に、上記位置規制用リブ２３をガイドにして上記ガイド部材６を位置決めし振動溶着する振動溶着工程５３を行う。
上記インストルメントパネル１の加工方法において、この実施例では、更に、上記開裂溝４の加工形成後（即ち、開裂溝形成工程５２と振動溶着工程５３との間）に、開裂溝４の形成位置に合わせて、上記位置規制用リブ２３の削除可能代３１のうち、不要な部分を削除する削除工程５４を行うようにする。
(3) The above-described instrument panel 1 is processed and formed as follows.
As shown in FIG. 8, first, on the back surface side, a cleavage groove formation scheduled portion 21 for forming a cleavage groove 4 that defines a lid portion 3 that is a planned opening portion, and a bag shape toward the lid portion 3. A welding planned portion 22 for fixing the guide member 6 capable of guiding the airbag body by vibration welding, a position regulating rib 23 for positioning the guide member 6 around the welding planned portion 22, and A molding step 51 for molding the instrument panel 1 having
Next, a cleavage groove forming step 52 is performed in which the cleavage groove 4 is processed and formed in the cleavage groove formation scheduled portion 21 of the instrument panel 1.
Then, a vibration welding process 53 is performed in which the guide member 6 is positioned and vibration welded to the planned welding portion 22 on the back surface of the instrument panel 1 in which the cleavage groove 4 is formed, using the position regulating rib 23 as a guide. .
In the processing method of the instrument panel 1, in this embodiment, the position where the cleavage groove 4 is formed after the formation of the cleavage groove 4 (that is, between the cleavage groove forming step 52 and the vibration welding step 53). At the same time, a deletion step 54 for deleting an unnecessary portion of the deleteable allowance 31 of the position regulating rib 23 is performed.
＜作用効果＞この実施例によれば、以下のような作用効果を得ることができる。
エアバッグ装置２は、緊急時に、エアバッグモジュール５内に折り畳んで収納されたエアバッグ本体が展開・膨張し、エアバッグモジュール５から出ると共に、ガイド部材６に案内されてインストルメントパネル１の裏面側に形成されたリッド部３を押圧してリッド部３を開き、インストルメントパネル１に開口部を形成することにより、車室内乗員側へ膨出する。これにより、膨出したエアバッグ本体によって、座席の所定位置に着座している乗員の身体を拘束し、乗員を保護することができる。
<Effect> According to this embodiment, the following effects can be obtained.
In the case of an emergency, the airbag device 2 is expanded and inflated by the airbag body folded and accommodated in the airbag module 5, exits from the airbag module 5, and is guided by the guide member 6 so that the back surface of the instrument panel 1. The lid portion 3 formed on the side is pressed to open the lid portion 3, and an opening is formed in the instrument panel 1 to bulge toward the passenger in the vehicle interior. Thereby, the body of the occupant seated at a predetermined position of the seat can be restrained and the occupant can be protected by the inflated airbag body.
そして、上記したインストルメントパネル１の作用効果は、以下の通りである。 And the effect of the above-mentioned instrument panel 1 is as follows.
（１）位置規制用リブ２３が、削除可能代３１を備えるようにした。これにより、開裂溝４の加工形成後に、開裂溝４の実際の形成位置に合わせて、位置規制用リブ２３の削除可能代３１を加工し、不要な部分を削除することにより、位置規制用リブ２３が正確なものとなる（即ち、開裂溝４の形成と位置規制用リブ２３の削除加工とが、同一基準位置に基いて行われることになるため、互いの位置精度が向上する）ので、位置規制用リブ２３によってガイド部材６を高精度に位置決めしてインストルメントパネル１に溶着固定することが可能となる。よって、開裂溝４に対するガイド部材６の取付け位置精度などが向上されるため、エアバッグ装置２の展開性能を向上することができる。 (1) The position regulating rib 23 is provided with a deletable allowance 31. Thereby, after the formation of the cleaving groove 4, the position restricting rib 31 is processed in accordance with the actual formation position of the cleaving groove 4, and unnecessary portions are deleted, thereby removing the position restricting rib. 23 is accurate (that is, the formation of the cleavage groove 4 and the deletion processing of the position regulating rib 23 are performed based on the same reference position, so that the positional accuracy of each other is improved) The position regulating rib 23 enables the guide member 6 to be positioned with high accuracy and fixed to the instrument panel 1 by welding. Therefore, since the mounting position accuracy of the guide member 6 with respect to the cleavage groove 4 is improved, the deployment performance of the airbag device 2 can be improved.
（２）位置規制用リブ２３としての前後規制リブ３５を車両前後方向の両側に設けるようにした。これにより、車両前後方向の位置決めを容易に行うことができるようになる。即ち、これまでは、前後規制リブ３５は、型抜き上、車両前後方向の片側にしか設けることができなかったので、車両前後方向の片側のみを前後規制リブ３５で位置規制して、反対側についてはセンサで監視してずれないように制御するなどしていたが、これだと、位置決め操作が難しく、正確な位置決めを行わせるのも難しかった。これに対し、車両前後方向の両側を前後規制リブ３５で位置規制させるようにした場合には、上記したように、容易に正確な位置決めが可能となる。 (2) The front and rear restricting ribs 35 as the position restricting ribs 23 are provided on both sides in the vehicle front and rear direction. Thereby, positioning in the vehicle front-rear direction can be easily performed. That is, until now, the front / rear restricting ribs 35 could only be provided on one side in the vehicle front-rear direction on the mold release, so that only one side in the vehicle front-rear direction is restricted by the front / rear restricting ribs 35 and However, it was difficult to perform accurate positioning because it was monitored by a sensor and controlled so as not to deviate. On the other hand, when the positions of both sides in the vehicle front-rear direction are restricted by the front-rear restricting ribs 35, accurate positioning can be easily performed as described above.
なお、前後規制リブ３５を車両前後方向の両側に設けることは、上記したように、型抜き上不可能となっていたが、上記したように、前後規制リブ３５の不要部分を後加工で削除する構成を採用すれば、型抜き可能な形状に作ってから不要部分をカットすることにより、前後規制リブ３５を車両前後方向の両側に設けること、しかも、精度の高い前後規制リブ３５を得ることが可能となる。 Note that providing the front and rear regulating ribs 35 on both sides in the vehicle longitudinal direction has been impossible to remove the die as described above, but as described above, unnecessary portions of the front and rear regulating ribs 35 are deleted by post-processing. By adopting such a configuration, the front / rear regulating ribs 35 are provided on both sides in the vehicle front-rear direction by cutting the unnecessary portion after making it into a moldable shape, and obtaining the front / rear regulating rib 35 with high accuracy. Is possible.
ここで、前後規制リブ３５については、車両前後方向の端部に設けられた削除可能代３１を削除することによって、長さを調整することになる。また、左右規制リブ３６については、肉厚を増加させるように設けられた削除可能代３１を削除して、厚みを調整することになる。 Here, the length of the front / rear regulating rib 35 is adjusted by deleting the deleteable allowance 31 provided at the end in the vehicle front-rear direction. Moreover, about the right-and-left control rib 36, the deletion allowance 31 provided so that thickness may be increased is deleted, and thickness is adjusted.
（３）そして、上記したインストルメントパネル１の加工方法によれば、開裂溝４の加工形成後（即ち、開裂溝形成工程５２と振動溶着工程５３との間）に、開裂溝４の形成位置に合わせて、上記位置規制用リブ２３の削除可能代３１のうち、不要な部分を削除する削除工程５４を行うことにより、上記と同様の作用効果を得ることができる。 (3) According to the processing method for the instrument panel 1 described above, the position where the cleavage groove 4 is formed after the formation of the cleavage groove 4 (that is, between the cleavage groove forming step 52 and the vibration welding step 53). In accordance with the above, by performing the deleting step 54 for deleting the unnecessary portion of the deleteable allowance 31 of the position regulating rib 23, the same effect as above can be obtained.
