　ところで、インストルメントパネルは、車室の前部に配置されるので、車両が衝突した際に乗員の上半身が前方へ倒れると、乗員の頭部がインストルメントパネルの上面側に衝突する可能性がある。特許文献１に記載の車両のようにインストルメントパネルは、車体側（インストレインフォース）に固定されるので、頭部の衝撃を吸収することが難しい。 By the way, since the instrument panel is arranged in the front part of the passenger compartment, if the passenger's upper body falls forward when the vehicle collides, there is a possibility that the passenger's head will collide with the upper surface side of the instrument panel. be. Since the instrument panel is fixed to the vehicle body side (instrain force) like the vehicle described in Patent Document 1, it is difficult to absorb the impact of the head.
　そこで、本開示は、インストルメントパネルの上面に乗員が衝突する際の乗員保護性能を向上させることが可能なインストルメントパネル取付構造の提供を目的とする。 Therefore, an object of the present disclosure is to provide an instrument panel mounting structure capable of improving occupant protection performance when an occupant collides with the upper surface of the instrument panel.
　上記課題を解決するため、本開示の第１の態様は、車室の前部に配置されるインストルメントパネルを車体側に取り付けるインストルメントパネル取付構造であって、車体側支持面部とインストルメントパネル支持部材とボルト及びナットとを備える。車体側支持面部は、車体側に固定的に設けられて上下方向に延びる。インストルメントパネル支持部材は、車体側支持面部に接触した状態で車体側支持面部に固定される固定板部と、インストルメントパネルを支持するパネル支持部とを有する。ボルト及びナットは、車体側支持面部とインストルメントパネル支持部材の固定板部とを締結固定する。インストルメントパネル支持部材の固定板部は、ボルトの挿通を許容するボルト挿通孔と、ボルト挿通孔から連続して上方へ延びるスリットとを有する。ボルトは、インストルメントパネル支持部材がインストルメントパネルを通常の高さ位置に支持している状態で、インストルメントパネル支持部材の固定板部のボルト挿通孔を挿通する。 In order to solve the above problems, a first aspect of the present disclosure is an instrument panel mounting structure for mounting an instrument panel disposed in the front part of a vehicle compartment on the vehicle body side, comprising: a vehicle body side support surface portion and the instrument panel; A support member and a bolt and nut are provided. The vehicle body side support surface portion is fixedly provided on the vehicle body side and extends in the vertical direction. The instrument panel support member has a fixed plate portion fixed to the vehicle body side support surface portion while being in contact with the vehicle body side support surface portion, and a panel support portion that supports the instrument panel. The bolt and nut fasten and fix the vehicle body side support surface portion and the fixing plate portion of the instrument panel support member. The fixing plate portion of the instrument panel support member has a bolt insertion hole through which the bolt is inserted, and a slit continuously extending upward from the bolt insertion hole. The bolt is inserted through the bolt insertion hole of the fixed plate portion of the instrument panel support member in a state in which the instrument panel support member supports the instrument panel at a normal height position.
　上記構成では、インストルメントパネル支持部材の固定板部は、ボルトの挿通を許容するボルト挿通孔と、ボルト挿通孔から連続して上方へ延びるスリットとを有し、ボルトは、インストルメントパネル支持部材がインストルメントパネルを通常の高さ位置に支持している状態で、インストルメントパネル支持部材の固定板部のボルト挿通孔を挿通する。このため、車両の衝突時等に、インストルメントパネルの上面に乗員が衝突し、インストルメントパネルに大きな荷重が入力した際に、ボルトをボルト挿通孔からスリット側へ相対的に移動させて、インストルメントパネルを下方へ移動させることができるので、インストルメントパネルから乗員側への衝撃を低減することができ、乗員保護性能を向上させることができる。 In the above configuration, the fixing plate portion of the instrument panel support member has a bolt insertion hole that allows the bolt to be inserted, and a slit that continuously extends upward from the bolt insertion hole, and the bolt is inserted into the instrument panel support member. supports the instrument panel at a normal height position, the bolt insertion holes of the fixing plate portion of the instrument panel support member are inserted. For this reason, when a passenger collides with the upper surface of the instrument panel in a vehicle collision, etc., and a large load is input to the instrument panel, the bolt is relatively moved from the bolt insertion hole toward the slit, Since the instrument panel can be moved downward, the impact from the instrument panel to the occupant side can be reduced, and the occupant protection performance can be improved.
　本開示の第２の態様は、上記第１の態様のインストルメントパネル取付構造であって、インストルメントパネル支持部材は、固定板部の上端から車体側支持面部とは反対側へ向かって延びる上板部を有する。インストルメントパネル支持部材の上板部は、固定板部のスリットから連続する開口を有する。インストルメントパネル支持部材の上板部の開口は、固定板部から車体側支持面部とは反対側に突出するボルト及びナットの突出領域がスリットに沿って上方へ相対的に移動してきた際に、突出領域の上板部よりも上方への相対的な移動を許容する大きさに形成される。 A second aspect of the present disclosure is the instrument panel mounting structure of the first aspect, wherein the instrument panel support member extends from the upper end of the fixing plate portion toward the side opposite to the vehicle body side support surface portion. It has a plate. The upper plate portion of the instrument panel support member has an opening continuous from the slit of the fixed plate portion. The opening of the upper plate portion of the instrument panel support member is such that when the protruding regions of the bolts and nuts protruding from the fixed plate portion to the side opposite to the vehicle body side support surface portion relatively move upward along the slits, It is formed in a size that allows relative movement of the protruding region above the upper plate portion.
　上記構成では、インストルメントパネル支持部材は、固定板部の上端から車体側支持面部とは反対側へ向かって延びる上板部を有し、上板部は、固定板部のスリットから連続する開口を有する。上板部の開口は、固定板部から車体側支持面部とは反対側に突出するボルト及びナットの突出領域がスリットに沿って上方へ相対的に移動してきた際に、上板部よりも上方への突出領域の相対的な移動を許容する大きさに形成される。このため、車両の衝突時等に、インストルメントパネルの上面に乗員が衝突し、インストルメントパネルに大きな荷重が入力し、ボルトがボルト挿通孔からスリットを介して上板部側へ相対的に移動してきた際に、ボルト及びナットの突出領域を上板部の開口から上方へ移動させることができるので、インストルメントパネル及びインストルメントパネル支持部材を車体側の車体側支持面部から下方へ脱落させることができる。従って、インストルメントパネルから乗員側への衝撃を低減することができるので、乗員保護性能を向上させることができる。 In the above configuration, the instrument panel support member has the upper plate portion extending from the upper end of the fixed plate portion toward the side opposite to the vehicle body side support surface portion, and the upper plate portion has an opening continuous from the slit of the fixed plate portion. have The opening of the upper plate portion is located above the upper plate portion when the protruding regions of the bolts and nuts protruding from the fixed plate portion to the side opposite to the vehicle body side support surface portion relatively move upward along the slits. It is sized to allow relative movement of the projecting region to. Therefore, in the event of a vehicle collision or the like, an occupant collides with the upper surface of the instrument panel, and a large load is input to the instrument panel, causing the bolt to move relatively from the bolt insertion hole toward the upper plate portion through the slit. When the instrument panel and the instrument panel supporting member are moved upward from the opening of the upper plate portion, the instrument panel and the instrument panel support member can be dropped downward from the vehicle body side support surface portion on the vehicle body side. can be done. Therefore, it is possible to reduce the impact from the instrument panel to the occupant side, so that the occupant protection performance can be improved.
　本開示の第３の態様は、上記第１の態様または上記第２の態様のインストルメントパネル取付構造であって、スリットの幅は、上記ボルト挿通孔の径よりも狭い幅に形成される。 A third aspect of the present disclosure is the instrument panel mounting structure of the first aspect or the second aspect, wherein the width of the slit is narrower than the diameter of the bolt insertion hole.
　上記構成では、スリットの幅は、固定板部のボルト挿通孔の径よりも狭い幅に形成されるので、ボルトがスリットを上方へ相対的に移動する際に、ボルトがスリットの縁に当接し易い。このため、ボルトがスリットを上方へ相対的に移動する際に、ボルトとスリットの縁との当接によって乗員の衝撃を吸収することができる。 In the above configuration, the width of the slit is formed to be narrower than the diameter of the bolt insertion hole of the fixed plate portion, so that when the bolt relatively moves upward in the slit, the bolt contacts the edge of the slit. easy. Therefore, when the bolt relatively moves upward in the slit, the impact of the occupant can be absorbed by the contact between the bolt and the edge of the slit.
　また、スリットの幅は、ボルト挿通孔の径よりも狭い幅に形成されるので、スリットの幅を適切に設定（例えば、ボルトの軸の径よりも狭く設定）することによって、小さな荷重の入力時等に、インストルメントパネルが簡単に下方へ移動してしまうことを防止することができる。 In addition, since the width of the slit is narrower than the diameter of the bolt insertion hole, setting the width of the slit appropriately (for example, setting it narrower than the diameter of the shaft of the bolt) allows the input of a small load. Sometimes, it is possible to prevent the instrument panel from easily moving downward.
　本開示によれば、インストルメントパネルの上面に乗員が衝突する際の乗員保護性能を向上させることができる。 According to the present disclosure, it is possible to improve the occupant protection performance when the occupant collides with the upper surface of the instrument panel.

It is screwed into the nut 7 on the side and tightened. When the panel support member 10 is fixed to the bracket 6 on the vehicle body side by tightening the bolt 8, the bolt shaft 8a of the bolt 8 is inserted through the bolt insertion hole 21 of the recessed bottom plate portion 19, and the head portion (protruding area) of the bolt 8 ) 8b projects rearward from the recess bottom plate portion 19 (on the side opposite to the vehicle body side support surface portion 6a of the bracket 6). The head portion 8b of the bolt 8 is arranged in the inner space 17 of the recess 14 and contacts the bottom plate portion 19 of the recess from behind. The width of the slit 22 (the length in the vehicle width direction) is such that when a load of a predetermined magnitude or more is input to the instrument panel 3 from above, the bolts will pass upward through the bolt insertion holes 21 of the recessed bottom plate portion 19 . 8 is set to a width that allows relative movement of the bolt shaft 8a. In this embodiment, the width of the slit 22 is set to be slightly narrower than the diameter of the bolt shaft 8a of the bolt 8. As shown in FIG. That is, the width of the slit 22 is set to be narrower than the diameter of the bolt insertion hole 21 of the bottom plate portion 19 of the recess.
　凹部上板部１８は、その前端縁から後方へ切り欠き状に形成される上部開口（開口）２３を有する。上部開口２３の前方は、凹部底板部１９のスリット２２の上端に連通する。上部開口２３の大きさは、パネル支持部材１０を車体側のブラケット６に固定した状態のボルト８が凹部底板部１９に対してスリット２２内を上方へ相対移動した際に、ボルト８のヘッド部８ｂが上部開口２３から凹部上板部１８よりも上方へ相対移動可能に、ボルト８のヘッド部８ｂよりも大きく形成される（図６参照）。たとえば、上部開口２３の幅（車幅方向の長さ）は、ボルト８のヘッド部８ｂの幅よりも大きい幅に形成される。上部開口２３の前後方向の長さは、ボルト８のヘッド部８ｂの前後方向の長さよりも、長く形成される。 The recessed upper plate portion 18 has an upper opening (opening) 23 that is formed in a cutout shape rearward from the front edge thereof. The front of the upper opening 23 communicates with the upper end of the slit 22 of the recess bottom plate portion 19 . The size of the upper opening 23 is determined by the head portion of the bolt 8 when the bolt 8 with the panel support member 10 fixed to the bracket 6 on the vehicle body side moves upward in the slit 22 relative to the bottom plate portion 19 of the recessed portion. 8b is formed to be larger than the head portion 8b of the bolt 8 so as to be relatively movable upward from the upper opening 23 relative to the recessed upper plate portion 18 (see FIG. 6). For example, the width (length in the vehicle width direction) of the upper opening 23 is formed to be larger than the width of the head portion 8b of the bolt 8 . The length of the upper opening 23 in the front-rear direction is longer than the length of the head portion 8b of the bolt 8 in the front-rear direction.

A bolt shaft 8a of a bolt 8 for fixing the panel support member 10 to the vehicle body side bracket 6 is inserted through the bolt insertion hole 21 of the recessed bottom plate portion 19 of the panel support member 10. As shown in FIG. By attaching the instrument panel 3 to the panel support member 10, the instrument panel 3 is arranged at a normal height position. When the instrument panel 3 is attached to the panel support member 10, the clip of the upper member 11 of the panel upright surface portion 3a is inserted into the upper clip insertion hole 15 of the lateral plate portion 13b of the panel support member 10 from above. Then, the clip of the lower member 12 of the panel upright surface portion 3a is inserted into the lower clip insertion hole 16 of the vertical plate portion 13a of the panel support member 10 from behind and locked. In a state in which the instrument panel 3 is attached to the panel support member 10, the horizontal plate portion 13b of the panel support member 10 supports the upper member 11 of the panel upright surface portion 3a of the instrument panel 3 from below, and the panel support member The vertical plate portion 13 a of the instrument panel 3 supports the lower member 12 of the panel rising surface portion 3 a of the instrument panel 3 . As a result, the instrument panel 3 is attached to the bracket 6 on the vehicle body side via the panel support member 10 in a state of being arranged at a normal height position.
　次に、インストルメントパネル３に対して上方から所定の大きさ以上の荷重が入力した際のインストルメントパネル３及びパネル支持部材１０の動きについて説明する。車両１の衝突時等に乗員の頭部がインストルメントパネル３のパネル上面部３ｂに（例えば、図７に示す白抜き矢印の方向へ）衝突すると、インストルメントパネル３に対して上方から下方への荷重が入力するとともに、インストルメントパネル３を介してパネル支持部材１０にも上方から下方への荷重が入力する。インストルメントパネル３に対して上方から上記所定の大きさ以上の荷重が入力すると、インストルメントパネル３が、パネル支持部材１０と共に、車体側のブラケット６の車体側支持面部６ａ及びボルト８・ナット７に対して上記通常の高さ位置から下方へ移動する。このとき、ボルト８のボルト軸８ａは、パネル支持部材１０の凹部底板部１９のボルト挿通孔２１からスリット２２内を上方へ相対的に移動する。そして、インストルメントパネル３及びパネル支持部材１０の下方への移動に伴って、ボルト８のボルト軸８ａが凹部底板部１９のスリット２２の上端から上方へ相対的に移動し、ボルト８のヘッド部８ｂが凹部上板部１８の上部開口２３から凹部上板部１８よりも上方へ相対的に移動すると、パネル支持部材１０がブラケット６（車体側支持面部６ａ）から下方へ脱落する。 Next, the movement of the instrument panel 3 and the panel support member 10 when a load of a predetermined size or more is input to the instrument panel 3 from above will be described. When the occupant's head collides with the panel upper surface portion 3b of the instrument panel 3 (for example, in the direction of the white arrow shown in FIG. 7) in the collision of the vehicle 1, etc., the instrument panel 3 is pushed downward from above. is input to the panel support member 10 through the instrument panel 3, and a load from above to below is also input to the panel support member 10. As shown in FIG. When a load equal to or larger than the predetermined magnitude is input to the instrument panel 3 from above, the instrument panel 3, together with the panel support member 10, is moved by the vehicle body side support surface portion 6a of the vehicle body side bracket 6 and the bolts 8 and nuts 7. relative to the normal height position. At this time, the bolt shaft 8 a of the bolt 8 relatively moves upward in the slit 22 from the bolt insertion hole 21 of the recess bottom plate portion 19 of the panel support member 10 . As the instrument panel 3 and the panel support member 10 move downward, the bolt shaft 8a of the bolt 8 relatively moves upward from the upper end of the slit 22 of the recessed bottom plate portion 19, and the head portion of the bolt 8 moves upward. When the panel support member 8b moves upward relative to the recessed upper plate portion 18 from the upper opening 23 of the recessed upper plate portion 18, the panel support member 10 drops downward from the bracket 6 (the vehicle body side support surface portion 6a).
　上記構成では、パネル支持部材１０の凹部底板部１９は、ボルト挿通孔２１と、ボルト挿通孔２１から連続して上方へ延びるスリット２２とを有する。パネル支持部材１０がインストルメントパネル３を通常の高さ位置に支持している状態で、ボルト８のボルト軸８ａは、パネル支持部材１０の凹部底板部１９のボルト挿通孔２１を挿通している。このため、車両１の衝突時等に、インストルメントパネル３の上面に乗員が衝突し、インストルメントパネル３に下方への大きな荷重が入力した際に、ボルト８を凹部底板部１９のボルト挿通孔２１から上方のスリット２２側へ相対的に移動可能であるので、インストルメントパネル３を、パネル支持部材１０と共に、車体側のブラケット６の車体側支持面部６ａ及びボルト８・ナット７に対して上記通常の高さ位置から下方へ移動させることができる。 In the above configuration, the recess bottom plate portion 19 of the panel support member 10 has the bolt insertion hole 21 and the slit 22 continuously extending upward from the bolt insertion hole 21 . With the panel support member 10 supporting the instrument panel 3 at a normal height, the bolt shaft 8a of the bolt 8 is inserted through the bolt insertion hole 21 of the recessed bottom plate portion 19 of the panel support member 10. . Therefore, when the vehicle 1 collides with the upper surface of the instrument panel 3 and a large downward load is applied to the instrument panel 3 by an occupant, the bolt 8 is inserted into the bolt insertion hole of the recessed bottom plate portion 19 . 21 relative to the upper slit 22 side, the instrument panel 3 can be moved together with the panel support member 10 with respect to the vehicle body side support surface portion 6a of the vehicle body side bracket 6 and the bolts 8 and nuts 7 as described above. It can be moved downward from the normal height position.
　また、パネル支持部材１０は、凹部底板部１９の上端から後方へ向かって延びる凹部上板部１８を有し、凹部上板部１８は、凹部底板部１９のスリット２２から連続する上部開口２３を有する。凹部上板部１８の上部開口２３は、凹部底板部１９から後方へ突出するボルト８のヘッド部８ｂがスリット２２に沿って上方へ相対的に移動してきた際に、凹部上板部１８よりも上方へのボルト８のヘッド部８ｂの相対的な移動を許容する大きさに形成される。このため、車両１の衝突時等に、インストルメントパネル３の上面に乗員が衝突し、インストルメントパネル３に大きな荷重が入力し、ボルト８が凹部底板部１９のボルト挿通孔２１からスリット２２を介して凹部上板部１８側へ相対的に移動してきた際に、ボルト８のヘッド部８ｂを凹部上板部１８の上部開口２３から上方へ移動させることができるので、インストルメントパネル３及びパネル支持部材１０を車体側のブラケット６（車体側支持面部６ａ）から下方へ脱落させることができる。 Further, the panel support member 10 has a recessed top plate portion 18 extending rearward from the upper end of the recessed bottom plate portion 19 , and the recessed top plate portion 18 has an upper opening 23 that continues from the slit 22 of the recessed bottom plate portion 19 . have. When the head portion 8b of the bolt 8 protruding rearward from the recessed bottom plate portion 19 moves relatively upward along the slit 22, the upper opening 23 of the recessed upper plate portion 18 is positioned higher than the recessed upper plate portion 18. It is sized to allow relative movement of the head portion 8b of the bolt 8 upward. Therefore, when the vehicle 1 collides or the like, an occupant collides with the upper surface of the instrument panel 3, a large load is input to the instrument panel 3, and the bolt 8 passes through the slit 22 from the bolt insertion hole 21 of the recessed bottom plate portion 19. When the head portion 8b of the bolt 8 can be moved upward from the upper opening 23 of the recessed upper plate portion 18 when the head portion 8b of the bolt 8 is relatively moved toward the recessed upper plate portion 18 side through the instrument panel 3 and the panel The support member 10 can be dropped downward from the vehicle body side bracket 6 (vehicle body side support surface portion 6a).
　また、凹部底板部１９のスリット２２の幅は、ボルト８のボルト軸８ａの径よりも狭い幅に設定されるので、ボルト８がスリット２２を上方へ相対的に移動する際に、ボルト８のボルト軸８ａがスリット２２の左右の縁に当接する。このため、ボルト８が凹部底板部１９のスリット２２を上方へ相対的に移動する際に、ボルト８とスリット２２の縁との当接によって乗員の衝撃を吸収することができる。 Further, since the width of the slit 22 of the recessed bottom plate portion 19 is set to be narrower than the diameter of the bolt shaft 8a of the bolt 8, when the bolt 8 relatively moves upward in the slit 22, the bolt 8 is The bolt shaft 8 a abuts on the left and right edges of the slit 22 . Therefore, when the bolt 8 relatively moves upward in the slit 22 of the recessed bottom plate portion 19 , the impact of the occupant can be absorbed by the contact between the bolt 8 and the edge of the slit 22 .
　従って、本実施形態によれば、インストルメントパネル３から乗員側への衝撃を低減することができるので、インストルメントパネル３の上面に乗員が衝突する際の乗員保護性能を向上させることができる。 Therefore, according to this embodiment, the impact from the instrument panel 3 to the occupant side can be reduced, so the occupant protection performance when the occupant collides with the upper surface of the instrument panel 3 can be improved.
　また、凹部底板部１９のスリット２２の幅は、ボルト８のボルト軸８ａの径よりも狭い幅に設定されるので、小さな荷重の入力時等に、インストルメントパネル３が簡単に下方へ移動してしまうことを防止することができる。 Further, since the width of the slit 22 of the recess bottom plate portion 19 is set to be narrower than the diameter of the bolt shaft 8a of the bolt 8, the instrument panel 3 can easily move downward when a small load is applied. You can prevent it from being lost.
　なお、本実施形態では、凹部底板部１９のスリット２２の幅を、ボルト８のボルト軸８ａの径よりも狭い幅に設定したが、これに限定されるものではなく、ボルト８のボルト軸８ａの径よりも広くしてもよい。例えば、凹部底板部１９のスリット２２の幅が、ボルト８のボルト軸８ａの径よりも広くても、凹部底板部１９のボルト挿通孔２１の径よりも狭ければ、ボルト８がスリット２２を上方へ相対的に移動する際に、ボルト８のボルト軸８ａがスリット２２の左右の縁に当接し易いので、ボルト８とスリット２２の縁との当接によって乗員の衝撃を吸収することができる。或いは、凹部底板部１９のスリット２２の幅を、凹部底板部１９のボルト挿通孔２１の径と略同じ幅にしてもよい。この場合であっても、ボルト８を凹部底板部１９のボルト挿通孔２１から上方のスリット２２側へ相対的に移動可能であるので、インストルメントパネル３に上方から上記所定の大きさ以上の荷重が入力した際にインストルメントパネル３を上記通常の高さ位置から下方へ移動させることができ、インストルメントパネル３から乗員側への衝撃を低減することができる。 In the present embodiment, the width of the slit 22 of the bottom plate portion 19 of the recess is set to be narrower than the diameter of the bolt shaft 8a of the bolt 8, but it is not limited to this. may be wider than the diameter of For example, even if the width of the slit 22 of the recessed bottom plate portion 19 is wider than the diameter of the bolt shaft 8a of the bolt 8, if it is narrower than the diameter of the bolt insertion hole 21 of the recessed bottom plate portion 19, the bolt 8 will pass through the slit 22. Since the bolt shaft 8a of the bolt 8 easily abuts against the left and right edges of the slit 22 when it moves relatively upward, the impact of the occupant can be absorbed by the abutment between the bolt 8 and the edges of the slit 22. . Alternatively, the width of the slit 22 of the recessed bottom plate portion 19 may be substantially the same as the diameter of the bolt insertion hole 21 of the recessed bottom plate portion 19 . Even in this case, the bolt 8 can be relatively moved from the bolt insertion hole 21 of the recessed bottom plate portion 19 toward the upper slit 22 side. is input, the instrument panel 3 can be moved downward from the normal height position, and the impact from the instrument panel 3 to the occupant side can be reduced.
　また、本実施形態では、パネル支持部材１０に凹部１４を設け、凹部底板部（固定板部）１９を車体側のブラケット６の車体側支持面部６ａへ固定したが、これに限定されるものではない。例えば、パネル支持部材１０に凹部１４を設けることなく、本体部１３にボルト挿通孔２１及びスリット２２を設け、本体部１３を車体側支持面部６ａへ固定する固定板部として機能させてもよい。この場合、スリット２２を本体部１３の上端まで延ばして上方ヘ開放してもよい。 Further, in the present embodiment, the panel support member 10 is provided with the recess 14, and the recess bottom plate portion (fixing plate portion) 19 is fixed to the vehicle body side support surface portion 6a of the vehicle body side bracket 6, but it is not limited to this. do not have.
