Description

本発明は、３列シート車両の左右それぞれに設けられる、後席用側突エアバッグセンサの取付構造に関する。   The present invention relates to a mounting structure for a rear-seat side airbag sensor provided on each of the left and right sides of a three-row seat vehicle.

車両がポール等に側面から衝突したとき、エアバッグを展開させて後席に着座している乗員を確実に保護する必要がある。とくに３列シート車両にあっては、リヤ１席に着座している乗員とリヤ２席に着座している乗員の両方を保護する必要がある。そのため、リヤ１席とリヤ２席の乗員の真横に１個ずつ、エアバッグセンサを配置（専用配置）することが望ましい。しかし、該専用配置をすると、センサ数が多くなり（左右で計４個）高コストである。   When a vehicle collides with a pole or the like from the side, it is necessary to reliably protect an occupant seated in a rear seat by deploying an airbag. In particular, in a three-row seat vehicle, it is necessary to protect both the passenger seated in the first rear seat and the passenger seated in the second rear seat. Therefore, it is desirable to arrange one airbag sensor (exclusive arrangement) right next to the occupants of the rear 1 seat and the rear 2 seats. However, when the dedicated arrangement is used, the number of sensors increases (four on the left and right sides), and the cost is high.

特許文献１は、加速度伝達部材をリヤホイールハウスフランジにのみ固着してホイールハウスに沿って上方まで延びる片持ち梁構造とすることで、センシングエリアを拡大した側突センサの取付構造を開示している。また、特許文献２は、リヤホイールハウスへの側突センサの取付構造を開示している。しかし、特許文献１，２は、２列シート車両に適用される技術を開示しているにすぎず、特許文献１，２記載の技術を３列シート車両に適用しようとすると、リヤ１席とリヤ２席の乗員の真横に１個ずつセンサを配置することになり、依然高コストの問題が残る。   Patent Document 1 discloses a mounting structure for a side collision sensor in which a sensing area is enlarged by fixing an acceleration transmission member only to a rear wheel house flange and a cantilever structure extending upward along the wheel house. Yes. Patent Document 2 discloses a structure for attaching a side collision sensor to a rear wheel house. However, Patent Documents 1 and 2 only disclose a technique applied to a two-row seat vehicle. If the technique described in Patent Documents 1 and 2 is applied to a three-row seat vehicle, One sensor will be placed right next to the passengers in the rear two seats, and the problem of high cost still remains.

そこで、コストを削減するために、リヤ１席とリヤ２席の車両前後方向中間にセンサを１個のみ配設してリヤ１席用センサとリヤ２席用センサを１センサ化すること（左右で計２個にすること）が考えられる。   Therefore, in order to reduce the cost, only one sensor is disposed in the middle of the vehicle front-rear direction of the rear 1 seat and the rear 2 seats so that the rear 1 seat sensor and the rear 2 seat sensor are integrated into one sensor (left and right). It is conceivable that the total number is 2).

しかし、リヤ１席とリヤ２席の車両前後方向中間にセンサを単純に１個のみ配設しても、リヤ１席とリヤ２席の乗員からの距離が遠くなるため、専用配置に比べてセンサのセンシング性能が悪化してしまう。
特開２００２−９６７０６号公報 特許第３４４０９０４号公報 However, even if only one sensor is installed in the vehicle longitudinal direction between the rear 1 seat and the rear 2 seats, the distance from the occupant of the rear 1 seat and the rear 2 seats is increased, so that The sensing performance of the sensor will deteriorate.
JP 2002-96706 A Japanese Patent No. 3440904

本発明の目的は、リヤ１席用センサとリヤ２席用センサを１センサ化することに伴うセンサのセンシング性能の悪化を抑制することができる、後席用側突センサの取付構造を提供することにある。   An object of the present invention is to provide a mounting structure for a rear-seat side collision sensor that can suppress deterioration in sensing performance of the sensor due to the rear 1-seat sensor and the rear 2-seat sensor being integrated into one sensor. There is.

上記（１）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
リヤホイールハウスのフランジの車両幅方向内側面にセンサを１個配設し、車両幅方向に延びる加速度伝達部材をリヤホイールハウスのフランジの車両幅方向外側面に接触して設けたため、車両がポール等にリヤ１席の真横またはリヤ２席の真横から衝突して（センサ配置位置から車両前後方向にオフセットした位置で衝突して）車両外板が車両幅方向内側に押し込まれたとき、衝突部位の周囲の車両外板も車両幅方向内側に引き込まれ、該引き込まれた外板により加速度伝達部材およびリヤホイールハウスのフランジが車両幅方向内側に押し込まれ、センサによって該フランジの加速度を検知できる。その結果、センサ配置位置と車両前後方向にオフセットした位置で衝突しても、加速度伝達部材で素早く加速度をリヤホイールハウスのフランジ（センサ搭載部）に伝達でき、リヤ１席用センサとリヤ２席用センサを１センサ化することに伴うセンサのセンシング性能の悪化を抑制することができる。 According to the above (1) rear seat side collision sensor mounting structure, the following effects can be obtained.
Since one sensor is arranged on the inner side surface of the rear wheel house flange in the vehicle width direction and the acceleration transmission member extending in the vehicle width direction is provided in contact with the outer side surface of the rear wheel house flange in the vehicle width direction, When the vehicle outer plate is pushed inward in the vehicle width direction by colliding from the side of the rear 1 seat or the side of the rear 2 seat (such as colliding at a position offset in the vehicle longitudinal direction from the sensor arrangement position) The vehicle outer plate around the vehicle is also drawn inward in the vehicle width direction, and the acceleration transmission member and the flange of the rear wheel house are pushed inward in the vehicle width direction by the drawn outer plate, and the acceleration of the flange can be detected by the sensor. As a result, even if a collision occurs between the sensor arrangement position and the position offset in the longitudinal direction of the vehicle, the acceleration transmission member can quickly transmit the acceleration to the flange (sensor mounting portion) of the rear wheel house. It is possible to suppress deterioration of the sensing performance of the sensor that accompanies the use of a single sensor.

また、上下方向に延びるとともに車両幅方向に延びる加速度伝達部材をリヤホイールハウスのフランジの車両幅方向外側面に接触して設けたため、加速度伝達部材がフランジの車両幅方向外側面に接触して設けられていない場合に比べてフランジの剛性が向上する。その結果、乗員によるトリム叩きなどでフランジが動いてしまい、その加速度をセンサが検知してエアバッグが展開してしまうこと（エアバッグの誤展開）を抑制できる。   Further, since the acceleration transmission member extending in the vertical direction and extending in the vehicle width direction is provided in contact with the outer side surface of the flange of the rear wheel house in the vehicle width direction, the acceleration transmission member is provided in contact with the outer side surface of the flange in the vehicle width direction. The rigidity of the flange is improved as compared with the case where it is not provided. As a result, it is possible to prevent the flange from moving due to a trim hit by an occupant, and the sensor detecting the acceleration to deploy the airbag (incorrect deployment of the airbag).

上記（２）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
センサがリヤホイールハウスの頂部から上方に延びるフランジに配設されているため、リヤホイールハウスが車両外板の車両幅方向内側への変形を邪魔して衝突時に車両外板で加速度伝達部材を車両幅方向内側に押し込むことができなくなることを抑制できる。その結果、リヤ１席の乗員の真横でポール等に衝突しても、リヤ２席の真横でポール等に衝突しても、リヤホイールハウスによって邪魔されずに確実に車両外板で加速度伝達部材を車両幅方向内側に押し込むことができる。 According to the mounting structure of the rear seat side collision sensor (2), the following effects can be obtained.
Since the sensor is disposed on the flange extending upward from the top of the rear wheel house, the rear wheel house prevents the vehicle outer plate from deforming inward in the vehicle width direction, and the vehicle outer plate causes the acceleration transmission member to be It is possible to suppress the inability to push inward in the width direction. As a result, even if it collides with a pole or the like right next to the occupant in the first rear seat, or even if it collides with a pole or the like right next to the second rear seat, the acceleration transmission member can be surely received by the vehicle outer plate without being disturbed by the rear wheel house. Can be pushed inward in the vehicle width direction.

上記（３）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
加速度伝達部材の車両幅方向外側端部と車両外板との間に所定の隙間が設定されているため、（ａ）車両が比較的高速でポール等に衝突した場合には、車両外板の車両幅方向内側への変形量が大きいため、隙間がなくなり加速度伝達部材で加速度をフランジに伝達できるが、（ｂ）車両が比較的低速でポール等に衝突した場合には、車両外板の車両幅方向内側への変形量が小さいため、隙間がなくならず、車両外板により加速度伝達部材が車両幅方向内側に押し込まれることを防止できる。その結果、エアバッグが不必要に展開してしまうことを防止できる。 According to the above (3) rear seat side collision sensor mounting structure, the following effects can be obtained.
Since a predetermined gap is set between the vehicle width direction outer side end portion of the acceleration transmission member and the vehicle outer plate, (a) when the vehicle collides with a pole or the like at a relatively high speed, Since the amount of deformation inward in the vehicle width direction is large, there is no gap and the acceleration transmission member can transmit the acceleration to the flange. (B) When the vehicle collides with a pole or the like at a relatively low speed, Since the amount of deformation inward in the width direction is small, there is no gap and it is possible to prevent the acceleration transmission member from being pushed inward in the vehicle width direction by the vehicle outer plate. As a result, the airbag can be prevented from being unnecessarily deployed.

上記（４）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
加速度伝達部材が車両幅方向外側端部に車両前後方向に所定量延びる延び部を備えているため、延び部が設けられていない場合に比べて、車両が衝突して車両外板が車両幅方向内側に変形してきたときに、加速度伝達部材と車両外板との接触面積を大きくできる。そのため、加速度伝達部材が車両外板を突き抜けてしまうことを防止できる。その結果、車両が衝突して車両外板が車両幅方向内側に変形してきたときに、車両外板で確実に加速度伝達部材を車両幅方向内側に押し込むことができる。 According to the above (4) rear seat side collision sensor mounting structure, the following effects can be obtained.
Since the acceleration transmission member includes an extending portion extending a predetermined amount in the vehicle front-rear direction at the vehicle width direction outer end portion, the vehicle collides and the vehicle outer plate moves in the vehicle width direction as compared with the case where the extending portion is not provided. When it has been deformed inward, the contact area between the acceleration transmission member and the vehicle outer plate can be increased. Therefore, the acceleration transmission member can be prevented from penetrating the vehicle outer plate. As a result, when the vehicle collides and the vehicle outer plate is deformed inward in the vehicle width direction, the acceleration transmission member can be reliably pushed inward in the vehicle width direction by the vehicle outer plate.

上記（５）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
加速度伝達部材が鉛直方向と平行または略平行に上下方向に延びている場合であっても、加速度伝達部材で車両外板の加速度をリヤホイールハウスのフランジ（センサ搭載部）に伝達できる。 According to the above (5) rear seat side collision sensor mounting structure, the following effects can be obtained.
Even when the acceleration transmission member extends in the vertical direction parallel to or substantially parallel to the vertical direction, the acceleration of the vehicle outer plate can be transmitted to the flange (sensor mounting portion) of the rear wheel house by the acceleration transmission member.

上記（６）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
加速度伝達部材が上方かつ車両前方または車両後方に傾斜して上下方向に延びている場合であっても、加速度伝達部材で車両外板の加速度をリヤホイールハウスのフランジ（センサ搭載部）に伝達できる。 According to the above (6) rear seat side collision sensor mounting structure, the following effects can be obtained.
Even when the acceleration transmission member is inclined upward and extending in the vertical direction in front of or behind the vehicle, the acceleration transmission member can transmit the acceleration of the vehicle outer plate to the flange (sensor mounting portion) of the rear wheel house. .

上記（７）の後席用側突センサの取付構造によれば、以下の効果を得ることができる。
加速度伝達部材が車両のＣピラーを構成するＣピラー構成部材に一体に形成されているため、加速度伝達部材がＣピラー構成部材と別体に形成されている場合に比べて、部品点数を削減できる。 According to the above (7) rear seat side collision sensor mounting structure, the following effects can be obtained.
Since the acceleration transmission member is integrally formed with the C pillar component member constituting the C pillar of the vehicle, the number of parts can be reduced as compared with the case where the acceleration transmission member is formed separately from the C pillar component member. .

以下に、本発明実施例の後席用側突センサの取付構造を、図１から図９を参照して、説明する。なお、図において、ＵＰは上方向を、ＦＲは車両前方向を、ＩＮは車両幅方向内側を、ＯＵＴは車両幅方向外側を示している。   Below, the mounting structure of the rear seat side collision sensor according to the embodiment of the present invention will be described with reference to FIGS.

However, FIGS. 1, 3, 5, and 6 are also applicable to the second embodiment of the present invention. Portions common to the first and second embodiments of the present invention are denoted by the same reference numerals throughout the first and second embodiments of the present invention.

〔実施例１〕
まず、本発明実施例１の構成を、図１から図６を参照して、説明する。
本発明実施例１の後席用側突センサの取付構造は、図１に示すように、３列シート車両の左右それぞれに設けられる後席用側突センサの取付構造である。 [Example 1]
First, the configuration of the first embodiment of the present invention will be described with reference to FIGS.
The rear seat side collision sensor mounting structure according to the first embodiment of the present invention is a rear seat side collision sensor mounting structure provided on each of the left and right sides of the three-row seat vehicle as shown in FIG.

センサ１０は、後席用側突エアバッグセンサである。センサ１０が側突を検知したとき、リヤ１席Ｒｒ１とリヤ２席Ｒｒ２の乗員を保護する図示略のエアバッグが膨張展開される。なお、エアバッグは、シートバックやサイドドアに設けたサイドエアバッグであってもよく、ルーフサイドに設けたカーテンエアバッグであってもよい。   The sensor 10 is a rear seat side airbag sensor. When the sensor 10 detects a side collision, an unillustrated airbag that protects the occupants of the first rear seat Rr1 and the second rear seat Rr2 is inflated and deployed. The airbag may be a side airbag provided on a seat back or a side door, or may be a curtain airbag provided on a roof side.

センサ１０は、通常使用時にリヤ１席Ｒｒ１のシートバックとリヤ２席Ｒｒ２のシートバックの車両前後方向の中間に頂部が位置するリヤホイールハウス３０に１個のみ（左右で２個のみ）配設される。リヤホイールハウス３０は、頂部よりも車両前方側の部分で、上下方向に延びるＣピラー６１（Ｃピラー６１のリンフォース）と溶接等することで固定されている。なお、Ｃピラー６１のリンフォースは、Ｃピラー６１のインナーパネルとアウターパネルの間に設けられる。   Only one sensor 10 is disposed in the rear wheel house 30 whose top is located in the middle of the vehicle front-rear direction between the seat back of the rear 1 seat Rr1 and the seat back of the rear 2 seat Rr2 during normal use (only 2 on the left and right). Is done. The rear wheel house 30 is fixed by welding or the like to a C pillar 61 (reinforce of the C pillar 61) extending in the vertical direction at a portion on the vehicle front side from the top. The reinforcement of the C pillar 61 is provided between the inner panel and the outer panel of the C pillar 61.

リヤホイールハウス３０は、図４に示すように、リヤホイールハウスインナ３１とリヤホイールハウスアウタ３２とで構成されており、車輪収容部を形成している。リヤホイールハウスインナ３１とリヤホイールハウスアウタ３２は、リヤホイールハウスインナ３１の車両幅方向外側端部に設けられ車輪収容部の半径方向外側に延びるインナフランジ３１ａと、リヤホイールハウスアウタ３２の車両幅方向内側端部に設けられ車輪収容部の半径方向外側に延びるアウタフランジ３２ａとを溶接等することで、互いに固定されている。インナフランジ３１ａとアウタフランジ３２ａとで、リヤホイールハウス３０のフランジ３３が構成される。フランジ３３の延び方向先端は自由端である。リヤホイールハウス３０の車両前側端部は、図２に示すように、車両前後方向に延びるロッカ４０の車両後側端部に溶接等することで固定されている。   As shown in FIG. 4, the rear wheel house 30 includes a rear wheel house inner 31 and a rear wheel house outer 32, and forms a wheel housing portion. The rear wheel house inner 31 and the rear wheel house outer 32 are provided at the outer end in the vehicle width direction of the rear wheel house inner 31 and extend radially outward of the wheel housing portion, and the vehicle width of the rear wheel house outer 32. They are fixed to each other by welding or the like to the outer flange 32a provided at the inner end in the direction and extending outward in the radial direction of the wheel accommodating portion. The inner flange 31a and the outer flange 32a constitute the flange 33 of the rear wheel house 30. The front end in the extending direction of the flange 33 is a free end. As shown in FIG. 2, the vehicle front side end portion of the rear wheel house 30 is fixed by welding or the like to the vehicle rear side end portion of the rocker 40 extending in the vehicle front-rear direction.

センサ１０は、フランジ３３の車両幅方向内側面に配設されている。センサ１０は、フランジ３３に、たとえば図示略のボルト等を用いて固定されている。センサ１０は、フランジ３３のうち、リヤホイールハウス３０の頂部（上端部とその近傍）から上方に延びるフランジに配設されている。なお、フランジ３３にセンサ１０を取付けるスペースがない場合には、フランジ３３の一部をその他の部分に比べて大きくすることでセンサ１０の取付けスペースが確保される。   The sensor 10 is disposed on the inner surface of the flange 33 in the vehicle width direction. The sensor 10 is fixed to the flange 33 using, for example, a bolt (not shown). The sensor 10 is disposed on a flange of the flange 33 that extends upward from the top portion (the upper end portion and the vicinity thereof) of the rear wheel house 30. In addition, when there is no space for mounting the sensor 10 on the flange 33, the mounting space for the sensor 10 is secured by making a part of the flange 33 larger than the other parts.

図５、図６に示すように、センサ１０に対応するフランジ３３車外側に加速度伝達部材２０が車両幅方向に延びて設けられている。上下方向と直交する方向の断面視で、加速度伝達部材２０の車両幅方向に延びる部分は、図５に示すように２本であってもよく、図６に示すように１本であってもよい。加速度伝達部材２０は、１部品構成であってもよく、複数部品構成であってもよい。   As shown in FIGS. 5 and 6, the acceleration transmission member 20 is provided on the outer side of the flange 33 corresponding to the sensor 10 so as to extend in the vehicle width direction. In a cross-sectional view perpendicular to the vertical direction, the acceleration transmitting member 20 may have two portions extending in the vehicle width direction as shown in FIG. 5 or one portion as shown in FIG. Good. The acceleration transmission member 20 may have a one-component configuration or a multi-component configuration.

加速度伝達部材２０は、フランジ３３の車両幅方向外側面の、センサ１０とフランジ３３を挟んで反対側の位置および／またはその近傍に、接触して設けられている。加速度伝達部材２０は、フランジ３３に、たとえば図示略のボルト等を用いて固定されている。センサ１０と加速度伝達部材２０が両方ともフランジ３３に図示略のボルトを用いて固定される場合、部品点数削減のためにセンサ１０と加速度伝達部材２０は１本のボルトでフランジ３３に固定されることが望ましい。   The acceleration transmission member 20 is provided in contact with a position on the outer side of the flange 33 in the vehicle width direction on the opposite side of the sensor 10 and the flange 33 and / or in the vicinity thereof. The acceleration transmission member 20 is fixed to the flange 33 using, for example, a bolt (not shown). When both the sensor 10 and the acceleration transmission member 20 are fixed to the flange 33 using bolts (not shown), the sensor 10 and the acceleration transmission member 20 are fixed to the flange 33 with one bolt to reduce the number of parts. It is desirable.

加速度伝達部材２０は、側突時に、車両外板５０によって押されて車両幅方向に移動することでフランジ３３に（センサ１０の取付け部に）加速度を伝達する部材である。加速度伝達部材２０は、たとえば金属製であり、側突時に車両外板５０によって車両幅方向内側に押されたときに、自身がほとんど変形せず確実にフランジ３３に（センサ１０の取付け部に）加速度を伝達できる程度の高剛性材料からなる。   The acceleration transmission member 20 is a member that transmits the acceleration to the flange 33 (to the mounting portion of the sensor 10) by being pushed by the vehicle outer plate 50 and moving in the vehicle width direction at the time of a side collision. The acceleration transmission member 20 is made of, for example, metal, and when it is pushed inward in the vehicle width direction by the vehicle outer plate 50 at the time of a side collision, the acceleration transmission member 20 is hardly deformed and surely becomes the flange 33 (to the mounting portion of the sensor 10) It is made of a highly rigid material that can transmit acceleration.

加速度伝達部材２０の車両幅方向外側端部と、該端部に車両幅方向外側から対向する車両外板５０との間には、所定の幅方向隙間Ｓが設定されている。加速度伝達部材２０は、車両幅方向外側端部に、車両前後方向に所定量延びる延び部２１を備える。延び部２１の車両幅方向外側面の面内方向は、延び部２１に車両幅方向外側から対向する車両外板５０の車両幅方向内側面の面内方向と、平行であってもよく、側突時に車両外板５０が延び部２１に面接触できるのであれば非平行であってもよい。   A predetermined width-direction gap S is set between the vehicle width direction outer side end portion of the acceleration transmission member 20 and the vehicle outer plate 50 facing the end portion from the vehicle width direction outer side. The acceleration transmission member 20 includes an extending portion 21 that extends a predetermined amount in the vehicle front-rear direction at an outer end portion in the vehicle width direction. The in-plane direction of the vehicle width direction outer side surface of the extending portion 21 may be parallel to the in-plane direction of the vehicle width direction inner side surface of the vehicle outer plate 50 facing the extending portion 21 from the vehicle width direction outer side. If the vehicle outer plate 50 extends and can come into surface contact with the portion 21 at the time of a collision, it may be non-parallel.

加速度伝達部材２０は、上下方向の広範囲にわたる側突時の加速度をフランジ３３（センサ１０の取付け部）に伝達できるように、図４に示すように、上下方向に延びている。加速度伝達部材２０は、直線状に上下方向に延びていてもよく、少なくとも１箇所車両前後方向に湾曲する図示略の湾曲部を有して上下方向に延びていてもよい。加速度伝達部材２０の上端は、フランジ３３の上端よりも上方に位置している。加速度伝達部材２０の下端は、フランジ３３の下端と同じかまたは略同じ上下方向位置にあってもよく、フランジ３３の下端よりも下方に位置していてもよい。加速度伝達部材２０の下端がフランジ３３の下端よりも下方に位置する場合、加速度伝達部材２０の、フランジ３３よりも下方に位置する部分の車両幅方向内側面は、加速度伝達部材２０が通常走行時等にがたつくことを防止するために、リヤホイールハウスアウタ３２の車両幅方向外側面に溶接等により固定されていることが望ましい。
以上の構成は、本発明実施例１だけでなく、本発明の他の実施例にも適用される。 As shown in FIG. 4, the acceleration transmission member 20 extends in the vertical direction so that the acceleration at the time of side collision over a wide range in the vertical direction can be transmitted to the flange 33 (attachment portion of the sensor 10).

The upper end of the acceleration transmission member 20 is located above the upper end of the flange 33. The lower end of the acceleration transmission member 20 may be at the same or substantially the same vertical position as the lower end of the flange 33, and may be positioned below the lower end of the flange 33. When the lower end of the acceleration transmission member 20 is located below the lower end of the flange 33, the inner side surface in the vehicle width direction of the portion of the acceleration transmission member 20 located below the flange 33 is when the acceleration transmission member 20 is running normally. In order to prevent rattling, it is desirable that the rear wheel house outer 32 is fixed to the outer surface in the vehicle width direction by welding or the like.
The above configuration is applied not only to the first embodiment of the present invention but also to other embodiments of the present invention.

ここで、本発明実施例１の作用を説明する。
本発明実施例１では、リヤホイールハウス３０のフランジ３３の車両幅方向内側面にセンサ１０を１個配設し、車両幅方向に延びる加速度伝達部材２０をフランジ３３の車両幅方向外側面に接触して設けたため、車両がポール等にリヤ１席Ｒｒ１の真横またはリヤ２席Ｒｒ２の真横から衝突して（センサ配置位置から車両前後方向にオフセットした位置で衝突して）車両外板５０が車両幅方向内側に押し込まれたとき、図３の点線にて示すように衝突部位の周囲の車両外板５０も車両幅方向内側に引き込まれ、該引き込まれた外板５０により加速度伝達部材２０およびリヤホイールハウス３０のフランジ３３が車両幅方向内側に押し込まれ、センサ１０によってフランジ３３の加速度を検知できる。その結果、センサ１０の配置位置と車両前後方向にオフセットした位置で衝突しても、加速度伝達部材２０で素早く加速度をリヤホイールハウス３０のフランジ３３（センサ搭載部）に伝達でき、リヤ１席用センサとリヤ２席用センサを１センサ化することに伴うセンサのセンシング性能の悪化を抑制することができる。 Here, the operation of the first embodiment of the present invention will be described.
In the first embodiment of the present invention, one sensor 10 is arranged on the inner surface of the flange 33 of the rear wheel house 30 in the vehicle width direction, and the acceleration transmission member 20 extending in the vehicle width direction contacts the outer surface of the flange 33 in the vehicle width direction. Therefore, the vehicle collides with the pole or the like from the side of the rear 1 seat Rr1 or the side of the rear 2 seat Rr2 (the vehicle collides at a position offset in the vehicle front-rear direction from the sensor arrangement position). When pushed inward in the width direction, the vehicle outer plate 50 around the collision part is also drawn inward in the vehicle width direction as shown by the dotted line in FIG. The flange 33 of the wheel house 30 is pushed inward in the vehicle width direction, and the acceleration of the flange 33 can be detected by the sensor 10. As a result, even if a collision occurs at the position where the sensor 10 is disposed and the position offset in the longitudinal direction of the vehicle, the acceleration transmission member 20 can quickly transmit the acceleration to the flange 33 (sensor mounting portion) of the rear wheel house 30 for one rear seat. Deterioration of the sensing performance of the sensor due to the integration of the sensor and the rear two-seat sensor into one sensor can be suppressed.

上下方向に延びるとともに車両幅方向に延びる加速度伝達部材２０をリヤホイールハウス３０のフランジ３３の車両幅方向外側面に接触して設けたため、加速度伝達部材２０がフランジ３３の車両幅方向外側面に接触して設けられていない場合に比べてフランジ３３の剛性が向上する。その結果、乗員によるトリム叩きなどでフランジ３３が動いてしまい、その加速度をセンサ１０が検知してエアバッグが展開（誤展開）してしまうことを抑制できる。   Since the acceleration transmission member 20 extending in the vertical direction and extending in the vehicle width direction is provided in contact with the outer surface in the vehicle width direction of the flange 33 of the rear wheel house 30, the acceleration transmission member 20 contacts the outer surface in the vehicle width direction of the flange 33. Therefore, the rigidity of the flange 33 is improved as compared with the case where the flange 33 is not provided. As a result, it is possible to suppress the flange 33 from moving due to a trim hit by an occupant and the sensor 10 detecting the acceleration to deploy (erroneously deploy) the airbag.

センサ１０がリヤホイールハウス３０の頂部から上方に延びるフランジ３３に配設されているため、リヤホイールハウス３０が車両外板５０の車両幅方向内側への変形を邪魔して衝突時に車両外板５０で加速度伝達部材２０を車両幅方向内側に押し込むことができなくなることを抑制できる。その結果、リヤ１席Ｒｒ１の乗員の真横でポール等に衝突しても、リヤ２席Ｒｒ２の真横でポール等に衝突しても、リヤホイールハウス３０によって邪魔されずに確実に車両外板５０で加速度伝達部材２０を車両幅方向内側に押し込むことができる。   Since the sensor 10 is disposed on the flange 33 extending upward from the top of the rear wheel house 30, the rear wheel house 30 interferes with the deformation of the vehicle outer plate 50 inward in the vehicle width direction, and the vehicle outer plate 50 at the time of collision. Thus, it is possible to prevent the acceleration transmission member 20 from being pushed inward in the vehicle width direction. As a result, even if it collides with a pole or the like right next to the occupant of the first rear seat Rr1, or even collides with a pole or the like right next to the second rear seat Rr2, the vehicle outer plate 50 is surely not obstructed by the rear wheel house 30. Thus, the acceleration transmission member 20 can be pushed inward in the vehicle width direction.

加速度伝達部材２０の車両幅方向外側端部と車両外板５０との間に所定の隙間Ｓが設定されているため、（ａ）車両が比較的高速でポール等に衝突した場合には、車両外板５０の車両幅方向内側への変形量が大きいため、隙間Ｓがなくなり加速度伝達部材２０で加速度がフランジ３３に伝達されるが、（ｂ）車両が比較的低速でポール等に衝突した場合には、車両外板５０の車両幅方向内側への変形量が小さいため隙間Ｓがなくならず、車両外板５０により加速度伝達部材２０が車両幅方向内側に押し込まれず、加速度伝達部材２０で加速度がフランジ３３に伝達されることを抑制できる。したがって、車両が比較的低速でポール等に衝突した場合等、エアバッグを展開させる必要がない場合、加速度の時間積分値が所定の閾値を越えず、エアバッグが不必要に展開（誤展開）してしまうことを防止できる。
また、隙間Ｓの量（車両幅方向長さ）を調節することで、どの程度で衝突したときにセンサ１０をＯＮさせるかを容易に調節できる。 Since a predetermined gap S is set between the vehicle width direction outer side end portion of the acceleration transmission member 20 and the vehicle outer plate 50, (a) when the vehicle collides with a pole or the like at a relatively high speed, the vehicle Since the amount of deformation of the outer plate 50 inward in the vehicle width direction is large, the clearance S is eliminated and the acceleration is transmitted to the flange 33 by the acceleration transmission member 20, but (b) the vehicle collides with a pole or the like at a relatively low speed. In this case, since the deformation amount of the vehicle outer plate 50 toward the inner side in the vehicle width is small, the gap S is not eliminated, and the acceleration transmission member 20 is not pushed inward in the vehicle width direction by the vehicle outer plate 50. Can be prevented from being transmitted to the flange 33. Therefore, when the airbag does not need to be deployed, such as when the vehicle collides with a pole or the like at a relatively low speed, the time integral value of acceleration does not exceed a predetermined threshold value, and the airbag is unnecessarily deployed (false deployment). Can be prevented.
In addition, by adjusting the amount of the gap S (the length in the vehicle width direction), it is possible to easily adjust how much the sensor 10 is turned on when a collision occurs.

加速度伝達部材２０が車両幅方向外側端部に車両前後方向に所定量延びる延び部２１を備えているため、延び部２１が設けられていない場合に比べて、車両が衝突して車両外板５０が車両幅方向内側に変形してきたときに、加速度伝達部材２０と車両外板５０との接触面積を大きくできる。そのため、加速度伝達部材２０が車両外板５０を突き抜けてしまうことを防止できる。その結果、車両が衝突して車両外板５０が車両幅方向内側に変形してきたときに、車両外板５０で確実に加速度伝達部材２０を車両幅方向内側に押し込むことができる。
以上の作用は本発明実施例１だけでなく、本発明の他の実施例にも適用される。 Since the acceleration transmission member 20 includes the extending portion 21 that extends a predetermined amount in the vehicle front-rear direction at the outer end portion in the vehicle width direction, the vehicle collides with the vehicle outer plate 50 as compared with the case where the extending portion 21 is not provided. , The contact area between the acceleration transmission member 20 and the vehicle outer plate 50 can be increased. Therefore, the acceleration transmission member 20 can be prevented from penetrating the vehicle outer plate 50. As a result, when the vehicle collides and the vehicle outer plate 50 is deformed inward in the vehicle width direction, the acceleration transmission member 20 can be reliably pushed inward in the vehicle width direction by the vehicle outer plate 50.
The above operation is applied not only to the first embodiment of the present invention but also to other embodiments of the present invention.

加速度伝達部材２０が鉛直方向と平行または略平行に上下方向に延びているため、加速度伝達部材２０が鉛直方向と平行または略平行に上下方向に延びている場合であっても、加速度伝達部材２０で車両外板５０の加速度をリヤホイールハウス３０のフランジ３３（センサ搭載部）に伝達できる。   Since the acceleration transmission member 20 extends in the vertical direction parallel to or substantially parallel to the vertical direction, even if the acceleration transmission member 20 extends in the vertical direction parallel to or substantially parallel to the vertical direction, the acceleration transmission member 20 Thus, the acceleration of the vehicle outer plate 50 can be transmitted to the flange 33 (sensor mounting portion) of the rear wheel house 30.

加速度伝達部材２０が、フランジ３３に固定されるだけでなく、上端部でパネル５１に固定されているため、通常走行時等に加速度伝達部材２０が車両に対してがたつくことを抑制できる。加速度伝達部材２０が、フランジ３３よりも下方部分でリヤホイールハウスアウタ３２に固定されている場合には、さらに加速度伝達部材２０が車両に対してがたつくことを抑制できる。   Since the acceleration transmission member 20 is not only fixed to the flange 33 but also fixed to the panel 51 at the upper end, it is possible to suppress the acceleration transmission member 20 from rattling against the vehicle during normal traveling or the like. When the acceleration transmission member 20 is fixed to the rear wheel house outer 32 at a portion below the flange 33, it is possible to further suppress the acceleration transmission member 20 from rattling against the vehicle.

〔実施例２〕
つぎに、本発明実施例２の、主に本発明実施例１と異なる部分を図７を参照して説明する。 [Example 2]
Next, portions of the second embodiment of the present invention which are different from the first embodiment of the present invention will be described with reference to FIG.

本発明実施例２では、加速度伝達部材２０は、上方かつ車両前方または車両後方に傾斜して上下方向に延びている（図７では、加速度伝達部材２０が上方かつ車両前方に傾斜して上下方向に延びている場合を示している）。
加速度伝達部材２０が上方かつ車両前方に傾斜して上下方向に延びている場合、加速度伝達部材２０は、部品点数削減のために車両のＣピラー６１を構成するＣピラー構成部材６０に一体に形成されていることが望ましい（図７では、加速度伝達部材２０がピラー構成部材６０に一体に形成されている場合を示している）。なお、Ｃピラー構成部材６０は、Ｃピラー６１のリンフォース、Ｃピラー６１のインナーパネルなどである。
加速度伝達部材２０がＣピラー構成部材６０に一体に形成される場合、加速度伝達部材２０は、Ｃピラー構成部材６０の下端部とその近傍の車両後方側壁を車両後方に変位させること（延ばすこと）により、形成される。 In the second embodiment of the present invention, the acceleration transmission member 20 is inclined upward and forward or backward in the vehicle (in FIG. 7, the acceleration transmission member 20 is inclined upward and forward of the vehicle in the vertical direction). Shows the case of
When the acceleration transmission member 20 is inclined upward and in the vertical direction and extends in the vertical direction, the acceleration transmission member 20 is formed integrally with the C pillar component member 60 constituting the C pillar 61 of the vehicle in order to reduce the number of parts. It is desirable that the acceleration transmission member 20 is integrally formed with the pillar component member 60 in FIG. The C pillar component 60 is a reinforcement of the C pillar 61, an inner panel of the C pillar 61, or the like.
When the acceleration transmission member 20 is formed integrally with the C pillar component member 60, the acceleration transmission member 20 displaces (extends) the lower end portion of the C pillar component member 60 and the vehicle rear side wall in the vicinity thereof toward the vehicle rear. Is formed.

次に、本発明実施例２の特有な作用を説明する。   Next, the specific operation of the second embodiment of the present invention will be described.

図８、図９は、加速度伝達部材２０が上方かつ車両前方に傾斜して上下方向に延びており、Ｃピラー構成部材６０に一体に形成されている場合を示している。
とくに、図８は、リヤホイールハウス３０の頂部から上方に延びるフランジ３３にセンサ１０を配設するだけでなく、さらにリヤ１席の真横にもセンサを配設した場合に、リヤ１席Ｒｒ１の真横からポール等に衝突した際の、加速度―時間のグラフである。なお、図８において、実線がリヤホイールハウス３０の頂部から上方に延びるフランジ３３に配設したセンサ１０で検知した場合を示しており、点線がリヤ１席の真横に配設したセンサで検知した場合を示している。この図から、リヤ１席の真横のセンサで検知した加速度が閾値を超えると略同時（越えた直後）に、センサ１０で検知した加速度が閾値を超えていることがわかる。
また、図９は、リヤホイールハウス３０の頂部から上方に延びるフランジ３３にセンサ１０を配設するだけでなく、さらにリヤ２席の真横にもセンサを配設した場合に、リヤ２席Ｒｒ２の真横からポール等に衝突した際の、加速度―時間のグラフである。なお、図９において、実線がリヤホイールハウス３０の頂部から上方に延びるフランジ３３に配設したセンサ１０で検知した場合を示しており、点線がリヤ２席の真横に配設したセンサで検知した場合を示している。この図から、リヤ２席の真横のセンサで検知した加速度が閾値を超えると略同時に、センサ１０で検知した加速度が閾値を超えていることがわかる。
したがって、リヤ１席用センサとリヤ２席用センサを１センサ化することに伴うセンサのセンシング性能の悪化を抑制できることがわかる。 8 and 9 show a case where the acceleration transmission member 20 is inclined upward and forward in the vehicle and extends in the vertical direction, and is integrally formed with the C pillar component member 60. FIG.
In particular, FIG. 8 shows that not only the sensor 10 is disposed on the flange 33 extending upward from the top of the rear wheel house 30, but also when the sensor is disposed directly beside the rear one seat, It is a graph of acceleration-time when it collides with a pole etc. from the side. In addition, in FIG. 8, the case where it detected with the sensor 10 arrange | positioned in the flange 33 extended upwards from the top part of the rear wheel house 30 is shown, and a dotted line is detected with the sensor arrange | positioned beside the rear 1 seat. Shows the case. From this figure, it can be seen that the acceleration detected by the sensor 10 exceeds the threshold almost simultaneously (immediately after the acceleration) detected by the sensor directly beside the rear seat exceeds the threshold.
Further, FIG. 9 shows that not only the sensor 10 is disposed on the flange 33 extending upward from the top of the rear wheel house 30, but also when the sensor is disposed directly next to the rear two seats, It is a graph of acceleration-time when it collides with a pole etc. from the side. In FIG. 9, the solid line shows the case detected by the sensor 10 disposed on the flange 33 extending upward from the top of the rear wheel house 30, and the dotted line is detected by the sensor disposed right next to the rear two seats. Shows the case. From this figure, it can be seen that the acceleration detected by the sensor 10 exceeds the threshold almost simultaneously when the acceleration detected by the sensor directly beside the two rear seats exceeds the threshold.
Therefore, it can be understood that the deterioration of the sensing performance of the sensor due to the rear 1 seat sensor and the rear 2 seat sensor being made into one sensor can be suppressed.

加速度伝達部材２０が上方かつ車両前方または車両後方に傾斜して上下方向に延びているため、加速度伝達部材２０が上方かつ車両前方または車両後方に傾斜して上下方向に延びている場合であっても、加速度伝達部材２０で車両外板５０の加速度をリヤホイールハウス３０のフランジ３３（センサ搭載部）に伝達できる。   Since the acceleration transmission member 20 is inclined upward and up and down in the vehicle front or rear direction, the acceleration transmission member 20 is inclined in the upper direction and front or rear of the vehicle and extends in the vertical direction. However, the acceleration transmitting member 20 can transmit the acceleration of the vehicle outer plate 50 to the flange 33 (sensor mounting portion) of the rear wheel house 30.

加速度伝達部材２０が車両のＣピラー６１を構成するＣピラー構成部材６０に一体に形成されている場合、加速度伝達部材２０がＣピラー構成部材６０と別体に形成されている場合に比べて、部品点数を削減できる。   When the acceleration transmission member 20 is integrally formed with the C pillar component member 60 constituting the C pillar 61 of the vehicle, compared to the case where the acceleration transmission member 20 is formed separately from the C pillar component member 60, The number of parts can be reduced.

加速度伝達部材２０がＣピラー構成部材６０に一体に形成されている場合、加速度伝達部材２０が、フランジ３３に固定されるだけでなく上端部でＣピラー構成部材６０に固定されることになるため、通常走行時等に加速度伝達部材２０が車両に対してがたつくことを抑制できる。加速度伝達部材２０が、フランジ３３よりも下方部分でリヤホイールハウスアウタ３２に固定されている場合には、さらに加速度伝達部材２０が車両に対してがたつくことを抑制できる。   When the acceleration transmission member 20 is formed integrally with the C pillar component member 60, the acceleration transmission member 20 is not only fixed to the flange 33 but also fixed to the C pillar component member 60 at the upper end. The acceleration transmission member 20 can be prevented from rattling with respect to the vehicle during normal traveling or the like. When the acceleration transmission member 20 is fixed to the rear wheel house outer 32 at a portion below the flange 33, it is possible to further suppress the acceleration transmission member 20 from rattling against the vehicle.
