Description

【０００１】
【発明の属する技術分野】
本発明は、車両を補強して車両側面から入力される荷重を有効に分散させる車両用側面補強構造に関する。
【０００２】
【従来の技術】
従来から、車両の側面衝突時に車両のドア又はピラーから入力される衝突荷重を効果的に分散させることを目的として、シートバック及びシートクッションの内部にそれぞれ第１補強部材、第２補強部材を設け、第１・第２補強部材の外端を左右のドアの上下部に設けた第３・第４補強部材にそれぞれ対峙させるとともに、第１・第２補強部材の内端をセンタートンネルの内部に設けた荷重伝達部材に対峙させたものがある（例えば特許文献１）。
【０００３】
このものによれば、車両の側面衝突により一方（例えば左側）のドアに入力された荷重が一方（例えば左側）の第１・第２補強部材、センタートンネル、他方（例えば右側）の第１・第２補強部材を介して他方（例えば右側）のドアに伝達される。したがって側面衝突による入力荷重が反対側のドアに伝達されて効果的に分散されることとなる。
【０００４】
【特許文献１】
特開平１１−２２２０８８号公報
【０００５】
【発明が解決しようとする課題】
しかしながら、この従来のものにおいては、車両に対して側面の高い位置（例えば車両のドアウィンドウ近傍位置）から荷重が入力された場合に、有効に入力荷重を分散することができない。
【０００６】
例えば、図５（ａ）及び図５（ｂ）にその模式図を示すように、車両２１の側面２１ａの高い位置２１ｂから移動車両２２による荷重入力があった場合は、その移動車両２２により入力される荷重Ｆｓが主としてまず第１補強部材２３のみに伝達されてしまう。それにより第１補強部材２３にその内端２３ａを中心とする回転力が加えられて図中右方向に回転してしまい、結果的に第１補強部材２３が荷重Ｆｓを分担できず、有効に荷重Ｆｓを分散することができなくなってしまう。
【０００７】
本発明は上記の事情に鑑みて為されたもので、車両に対して側面の高い位置から荷重が入力された場合であっても、両補強部材が荷重を分担することができ、有効に荷重を分散することができる車両用側面補強構造を提供することを課題とする。
【０００８】
【課題を解決するための手段】
上記の課題を解決するために、本発明の請求項に係る車両用側面補強構造は、車両のシートのシートバックに、車両の車室側面側から車室中央側に向けて下方に傾斜するように車両の幅方向に沿って延びる上側補強部材と、車両の車室側面側から車室中央側に向けて車両の幅方向に沿って略水平に延びる下側補強部材とが設けられ、下側補強部材が上側補強部材よりも下方に配置されるとともに、両補強部材の車室中央側端部が車室中央側に設けられた荷重伝達部材に対峙され、かつ、両補強部材の車室側面側端部近傍において両補強部材が側面側連結部材によって連結されていることを特徴とする。
【０００９】
この請求項に係る発明によれば、上側補強部材及び下側補強部材の車室側面側端部近傍において両補強部材が側面側連結部材によって連結されているので、車両に対して側面の高い位置から荷重が入力された場合であっても上側補強部材が中央側端部を中心として下側補強部材から独立して回転することはない。したがって、両補強部材が入力荷重を分担することができ、有効に入力荷重を分散することができる。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態に係る車両用側面補強構造を、図面を参照しつつ説明する。
【００１１】
図１は、この車両用側面補強構造を備えた車両１の要部斜視図である。この車両１は車室Ｒを有している。その車室Ｒは乗員が乗り込むためのスペースであり、車幅方向左右が車体パネルとしての運転席側ドアパネル２ａ、助手席側ドアパネル２ｂで囲まれている。
【００１２】
その車室Ｒ内には運転席シート３、助手席シート４が備えられている。車両用側面補強構造は、運転席シート３及び助手席シート４の内部にそれぞれ設けられており、車両１の中央を通り前後に延びる鉛直面に対して対称である他は同様の構造であるので、以下、運転席側についてのみ説明することとする。
【００１３】
図２は、この車両用側面補強構造を備えた運転席シート３の内部構造を示す図である。この運転席シート３は乗員（運転者）の頭部を支えるヘッドレスト５、乗員の背中や腰等の上半身を支えるシートバック６、乗員が着座するためのシートクッション７により大略構成される。
【００１４】
シートバック６の内部には、シートバック６の構造体としてのシートバックフレーム８が設けられている。このシートバックフレーム８はシートバック６の強度を確保するために鉄・アルミニウム等の金属で構成されたフレームであり、正面から見て略長方形とされている。
【００１５】
シートバックフレーム８には、図に示すように上側補強部材９と下側補強部材１０とが固定されている。これらの両補強部材９，１０は、この車両１に側面から移動車両１１（図３参照）による荷重入力があった場合に、その荷重Ｆを負担して分散させるためのものであり、シートバック６の内部に設けられている。
【００１６】
上側補強部材９は、車室Ｒの側面側すなわち運転席側ドアパネル２ａ側から車室Ｒの中央側に向けて下方に傾斜して車両１の幅方向に沿って延びるように設けられている。下側補強部材１０は、上側補強部材９よりも下方に配置され、かつ、運転席側ドアパネル２ａ側から車室Ｓの中央側に向けて車両１の幅方向に沿って略水平に延びるように設けられている。
【００１７】
車室Ｓの中央側には、荷重伝達部材としてのセンタートンネル１２が形成されており、この上側補強部材９の車室中央側端部（以下、内側端部という）９ａ及び下側補強部材１０の車室中央側端部（以下、内側端部という）１０ａがこのセンタートンネル１２に対峙している。
【００１８】
下側補強部材１０の車室側面側端部（以下、外側端部という）１０ｂは、上側補強部材９の車室側面側端部（以下、外側端部という）９ｂよりも、運転席側ドアパネル２ａ側に向けて突出している。それにより、下側補強部材１０の外側端部１０ｂと運転席側ドアパネル２ａとの間隔（図２中Ｌ１）が、上側補強部材９の外側端部９ｂと運転席側ドアパネル２ａとの間隔（図２中Ｌ２）よりも小さくされている。
【００１９】
下側補強部材１０の外側端部１０ｂを、上側補強部材９の外側端部９ｂよりも運転席側ドアパネル２ａ側に向けて突出させることにより、簡単な構造で下側補強部材１０の外側端部１０ｂと運転席側ドアパネル２ａとの間隔Ｌ１を、上側補強部材９の外側端部９ｂと運転席側ドアパネル２ａとの間隔Ｌ２よりも小さいものとすることができる。
【００２０】
上側補強部材９の内側端部９ａ近傍及び下側補強部材１０の内側端部１０ａ近傍において、両補強部材９，１０が中央側連結部材としての内側ブラケット１３によって連結されている。また、上側補強部材９の外側端部９ｂ近傍及び下側補強部材１０の外側端部１０ｂ近傍において、両補強部材９，１０が側面側連結部材としての外側ブラケット１４によって連結されている。
【００２１】
この両補強部材９，１０と内側ブラケット１３との連結及び両補強部材９，１０と外側ブラケット１４との連結は、例えばボルトによるものであっても、溶接によるものであってもよい。また、上側補強部材９、下側補強部材１０、内側ブラケット１３、外側ブラケット１４が一体に形成されていてもよい。
【００２２】
次に、この車両用側面補強構造を備えた車両１の側面に入力された荷重Ｆが分散される様子を説明する。
【００２３】
図３は、この車両１の側面（この図では運転席側ドア１５）に移動車両１１が接触し、車両１に荷重Ｆが加えられた様子を示す図である。移動車両１１が車両１へと近づいて運転席側ドア１５に接触し車両１に荷重Ｆが入力されると、運転席側ドア１５が変形しつつ運転席シート３に近づく。
【００２４】
下側補強部材１０の外側端部１０ｂと運転席側ドアパネル２ａとの間隔が上側補強部材９の外側端部９ｂと運転席側ドアパネル２ａとの間隔よりも小さくされているので、移動車両１１による荷重Ｆが高い位置１５ａに入力された場合であっても運転席側ドアパネル２ａは上側補強部材９の外側端部９ｂよりも先に下側補強部材１０の外側端部１０ｂに接触する。
【００２５】
その後さらに移動車両１１が車両１へと近づくと運転席側ドア１５の変形が進行し、運転席側ドアパネル２ａが上側補強部材９の外側端部９ｂに接触する。運転席側ドアパネル２ａが接触することにより、上側補強部材９には内側端部９ａを中心として図３中右方向の回転力が加えられる。
【００２６】
しかしながら、下側補強部材１０は、その外側端部１０ｂが上側補強部材９の外側端部９ｂよりも先に運転席側ドアパネル２ａに接触し、かつ、その内側端部１０ａもセンタートンネル１２に接触して運転席側ドアパネル２ａとセンタートンネル１２とに挟まれた状態となっている。さらに外側端部９ｂ，１０ｂ近傍において両補強部材９，１０が外側ブラケット１４によって連結されているので、上側補強部材９に回転力が加えられても、運転席側ドアパネル２ａとセンタートンネル１２とに挟まれた下側補強部材１０によって上側補強部材９の回転が防止されることとなる。
【００２７】
それにより、上側補強部材９は回転してしまうことなくその外側端部９ｂが運転席側ドアパネル２ａに当接し、さらにその内側端部９ａがセンタートンネル１２に当接して上側補強部材９は荷重Ｆを有効に分担することとなる。上側補強部材９により分担された荷重Ｆは、下側補強部材１０により分担された荷重Ｆとともにセンタートンネル１２に伝達され、図示しない助手席側の上側補強部材及び下側補強部材を介して助手席側ドアパネルに向けて有効に分散されることとなる。
【００２８】
なお、本実施の形態においては、上側補強部材９の内側端部９ａ近傍及び下側補強部材１０の内側端部１０ａ近傍においても両補強部材９，１０が内側ブラケット１３によって連結されているので、上側補強部材９の回転はより一層効果的に防止されることとなる。
【００２９】
さらに、本実施の形態においては、運転席側ドア１５の高い位置１５ａから荷重Ｆが入力された場合を説明したが、もちろんそのような場合に限られるものでなく、運転席側ドア１５の低い位置から荷重が入力された場合であっても、本発明は同様の効果を得ることができる。
【００３０】
本実施の形態に係る車両用側面補強構造によれば、下側補強部材１０の外側端部１０ｂと運転席側ドアパネル２ａとの間隔が上側補強部材９の外側端部９ｂと運転席側ドアパネル２ａとの間隔よりも小さくされているので、荷重の入力位置や入力方向に応じて、例え下側補強部材１０の外側端部１０ｂよりも上側補強部材９の外側端部９ｂの方が先に運転席側ドアパネル２ａに接触した場合であっても、その直後に下側補強部材１０の外側端部１０ｂが運転席側ドアパネル２ａに接触することとなる。したがって、下側補強部材９は運転席側ドアパネル２ａとセンタートンネル１２とに挟まれた状態となって、やはり有効に上側補強部材９の回転を防止することがき、入力荷重を両補強部材９，１０で有効に分担することができて、有効に荷重分散することができる。
【００３１】
［変形例］
上記実施の形態においては、上側補強部材９と下側補強部材１０とをそれらの内側端部９ａ，１０ａ近傍及び外側端部９ｂ，１０ｂ近傍において、それぞれ内側ブラケット１３及び外側ブラケット１４により連結したが、図４に示すように、内側ブラケット及び外側ブラケットがシートバックフレーム８であってもよい。
【００３２】
すなわち、シートバックフレーム８自体を両補強部材９，１０を連結する内側ブラケット及び外側ブラケットとして利用し、両補強部材９，１０をその内側端部９ａ，１０ａ近傍及び外側端部９ｂ，１０ｂ近傍においてシートバック８に直接取り付ける。それにより、別途連結部材としての内側ブラケット、外側ブラケットを用意する必要がなく、車両１の部品点数・製造コスト・重量の低減に寄与することができる。
【００３３】
さらに、上側補強部材９と下側補強部材１０とシートバックフレーム８とが一体に形成されていてもよい。それによりさらなる部品点数の削減を行うことができる。
【００３４】
【発明の効果】
以上説明したように、本願の請求項に係る発明によれば、上側補強部材及び下側補強部材の車室側面側端部近傍において両補強部材が側面側連結部材によって連結されているので、車両に対して側面の高い位置から荷重が入力された場合であっても上側補強部材が中央側端部を中心として下側補強部材から独立して回転することはない。したがって、両補強部材が入力荷重を分担することができ、有効に入力荷重を分散することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle side reinforcing structure that reinforces a vehicle and effectively distributes a load input from the vehicle side.
[0002]
[Prior art]
Conventionally, a first reinforcing member and a second reinforcing member are provided inside a seat back and a seat cushion, respectively, for the purpose of effectively dispersing a collision load input from a vehicle door or a pillar at the time of a side collision of a vehicle. The outer ends of the first and second reinforcing members are respectively opposed to third and fourth reinforcing members provided at the upper and lower portions of the left and right doors, and the inner ends of the first and second reinforcing members are located inside the center tunnel. There is one that faces the provided load transmitting member (for example, Patent Document 1).
[0003]
According to this, the load input to one (for example, left) door due to a side collision of the vehicle is one (for example, left) of the first and second reinforcing members, the center tunnel, and the other (for example, right) of first (for example, right). The power is transmitted to the other (eg, right) door via the second reinforcing member. Therefore, the input load due to the side collision is transmitted to the door on the opposite side and is effectively dispersed.
[0004]
[Patent Document 1]
JP-A-11-222088 [0005]
[Problems to be solved by the invention]
However, according to this conventional device, when a load is input from a high position on the side of the vehicle (for example, near the door window of the vehicle), the input load cannot be effectively dispersed.
[0006]
For example, as shown in FIGS. 5A and 5B, when a load is input by the moving vehicle 22 from a high position 21b on the side surface 21a of the vehicle 21, the load is input by the moving vehicle 22. The applied load Fs is primarily transmitted only to the first reinforcing member 23. As a result, a rotational force is applied to the first reinforcing member 23 about its inner end 23a, and the first reinforcing member 23 rotates rightward in the drawing. As a result, the first reinforcing member 23 cannot share the load Fs, and is effectively used. The load Fs cannot be dispersed.
[0007]
The present invention has been made in view of the above circumstances, and even when a load is input from a high position on a side surface of a vehicle, both reinforcing members can share the load, and the load can be effectively reduced. It is an object of the present invention to provide a vehicle side reinforcing structure capable of dispersing the above.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a vehicle side reinforcing structure according to the present invention is provided such that a seat back of a vehicle seat is inclined downward from a vehicle side surface side toward a vehicle center side toward a vehicle center side. An upper reinforcing member extending along the width direction of the vehicle, and a lower reinforcing member extending substantially horizontally along the width direction of the vehicle from the side of the cabin toward the center of the cabin of the vehicle. The reinforcing member is disposed below the upper reinforcing member, and the ends of both reinforcing members on the vehicle center side face the load transmitting member provided on the vehicle center side, and the side surfaces of both reinforcing members are provided. The two reinforcing members are connected by a side connecting member near the side end.
[0009]
According to the invention according to this claim, since the two reinforcing members are connected by the side connecting members near the vehicle side surface side end portions of the upper reinforcing member and the lower reinforcing member, the side surface is positioned higher than the vehicle. Even when a load is input from the upper side, the upper reinforcing member does not rotate about the center side end independently of the lower reinforcing member. Therefore, both reinforcement members can share the input load, and the input load can be effectively dispersed.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a vehicle side reinforcing structure according to an embodiment of the present invention will be described with reference to the drawings.
[0011]
FIG. 1 is a perspective view of a main part of a vehicle 1 provided with the vehicle side reinforcing structure. This vehicle 1 has a cabin R. The passenger compartment R is a space for an occupant to get in, and the left and right sides in the vehicle width direction are surrounded by a driver side door panel 2a and a passenger side door panel 2b as body panels.
[0012]
In the cabin R, a driver seat 3 and a passenger seat 4 are provided. The vehicle side reinforcement structure is provided inside the driver's seat 3 and the passenger's seat 4, respectively, and has the same structure except that it is symmetrical with respect to a vertical plane extending back and forth through the center of the vehicle 1. Hereinafter, only the driver's seat side will be described.
[0013]
FIG. 2 is a view showing the internal structure of the driver's seat 3 provided with the vehicle side reinforcing structure. The driver's seat 3 generally includes a headrest 5 for supporting the head of the occupant (driver), a seatback 6 for supporting the upper body of the occupant such as the back and waist, and a seat cushion 7 for the occupant to sit on.
[0014]
Inside the seat back 6, a seat back frame 8 as a structure of the seat back 6 is provided. The seat back frame 8 is a frame made of a metal such as iron or aluminum to secure the strength of the seat back 6, and has a substantially rectangular shape when viewed from the front.
[0015]
An upper reinforcing member 9 and a lower reinforcing member 10 are fixed to the seat back frame 8 as shown in the figure. These two reinforcing members 9 and 10 are for supporting and distributing the load F when the vehicle 1 receives a load input from the side by the moving vehicle 11 (see FIG. 3). 6 is provided inside.
[0016]
The upper reinforcing member 9 is provided so as to be inclined downward from the side surface side of the vehicle compartment R, that is, from the driver's seat side door panel 2a side toward the center side of the vehicle compartment R, and to extend along the width direction of the vehicle 1. The lower reinforcing member 10 is disposed below the upper reinforcing member 9, and extends substantially horizontally along the width direction of the vehicle 1 from the driver's seat side door panel 2 a toward the center of the passenger compartment S. Is provided.
[0017]
A center tunnel 12 as a load transmitting member is formed at the center side of the passenger compartment S. A central end (hereinafter, referred to as an inner end) 9a of the upper reinforcing member 9 and a lower reinforcing member 10 are provided. The center end (hereinafter, referred to as an inner end) 10 a of the vehicle room faces the center tunnel 12.
[0018]
The side end (hereinafter, referred to as an outer end) 10b of the lower reinforcing member 10 is closer to the driver's seat side than the inner side end (hereinafter, referred to as an outer end) 9b of the upper reinforcing member 9. It protrudes toward the 2a side. Thereby, the distance between the outer end portion 10b of the lower reinforcing member 10 and the driver's seat side door panel 2a (L1 in FIG. 2) is larger than the distance between the outer end portion 9b of the upper reinforcing member 9 and the driver's seat side door panel 2a (see FIG. 2 is smaller than L2).
[0019]
The outer end 10b of the lower reinforcing member 10 is projected toward the driver's seat side door panel 2a side from the outer end 9b of the upper reinforcing member 9 so that the outer end of the lower reinforcing member 10 has a simple structure. The distance L1 between the driver's seat side door panel 2a and 10b can be made smaller than the distance L2 between the outer end 9b of the upper reinforcing member 9 and the driver's seat side door panel 2a.
[0020]
Near the inner end 9a of the upper reinforcing member 9 and near the inner end 10a of the lower reinforcing member 10, the two reinforcing members 9, 10 are connected by an inner bracket 13 as a center side connecting member. Further, near the outer end 9b of the upper reinforcing member 9 and near the outer end 10b of the lower reinforcing member 10, the two reinforcing members 9, 10 are connected by an outer bracket 14 as a side connecting member.
[0021]
The connection between the reinforcing members 9 and 10 and the inner bracket 13 and the connection between the reinforcing members 9 and 10 and the outer bracket 14 may be by, for example, bolts or welding. Further, the upper reinforcing member 9, the lower reinforcing member 10, the inner bracket 13, and the outer bracket 14 may be integrally formed.
[0022]
Next, how the load F input to the side surface of the vehicle 1 provided with the vehicle side reinforcing structure is dispersed will be described.
[0023]
FIG. 3 is a diagram showing a state in which the moving vehicle 11 comes into contact with a side surface (the driver's seat side door 15 in this figure) of the vehicle 1 and a load F is applied to the vehicle 1. When the moving vehicle 11 approaches the vehicle 1 and contacts the driver's seat side door 15 and the load F is input to the vehicle 1, the driver's seat side door 15 is deformed and approaches the driver's seat 3.
[0024]
The distance between the outer end 10b of the lower reinforcing member 10 and the driver's seat side door panel 2a is smaller than the distance between the outer end 9b of the upper reinforcing member 9 and the driver's seat side door panel 2a. Even when the load F is input to the high position 15a, the driver's seat side door panel 2a contacts the outer end 10b of the lower reinforcing member 10 before the outer end 9b of the upper reinforcing member 9.
[0025]
Thereafter, when the moving vehicle 11 further approaches the vehicle 1, the deformation of the driver's seat side door 15 progresses, and the driver's seat side door panel 2a comes into contact with the outer end portion 9b of the upper reinforcing member 9. When the driver's seat side door panel 2a comes into contact, a rotational force in the right direction in FIG. 3 is applied to the upper reinforcing member 9 about the inner end 9a.
[0026]
However, the lower reinforcing member 10 has its outer end 10b contacting the driver's seat side door panel 2a before the outer end 9b of the upper reinforcing member 9 and its inner end 10a also contacts the center tunnel 12. As a result, the vehicle is sandwiched between the driver's seat side door panel 2a and the center tunnel 12. Further, since the reinforcing members 9 and 10 are connected by the outer brackets 14 in the vicinity of the outer end portions 9b and 10b, even if a rotational force is applied to the upper reinforcing member 9, the driver's seat side door panel 2a and the center tunnel 12 are connected. The lower reinforcing member 10 sandwiched therebetween prevents the upper reinforcing member 9 from rotating.
[0027]
As a result, the outer end portion 9b of the upper reinforcing member 9 abuts on the driver's seat side door panel 2a without rotating, and the inner end portion 9a of the upper reinforcing member 9 abuts on the center tunnel 12. Will be effectively shared. The load F shared by the upper reinforcing member 9 is transmitted to the center tunnel 12 together with the load F shared by the lower reinforcing member 10, and passes through the upper reinforcing member and the lower reinforcing member (not shown) of the passenger seat. It will be effectively dispersed toward the side door panel.
[0028]
In the present embodiment, since the two reinforcing members 9 and 10 are connected by the inner bracket 13 also near the inner end 9a of the upper reinforcing member 9 and near the inner end 10a of the lower reinforcing member 10, The rotation of the upper reinforcing member 9 is more effectively prevented.
[0029]
Further, in the present embodiment, the case where the load F is input from the high position 15a of the driver's seat side door 15 has been described. However, the present invention is not limited to such a case. The present invention can achieve the same effect even when a load is input from a position.
[0030]
According to the vehicle side reinforcing structure according to the present embodiment, the distance between the outer end 10b of the lower reinforcing member 10 and the driver's seat side door panel 2a is equal to the outer end 9b of the upper reinforcing member 9 and the driver's seat side door panel 2a. According to the input position and the input direction of the load, the outer end portion 9b of the upper reinforcing member 9 operates earlier than the outer end portion 10b of the lower reinforcing member 10, for example. Even in the case of contact with the seat side door panel 2a, the outer end 10b of the lower reinforcing member 10 comes into contact with the driver's seat side door panel 2a immediately thereafter. Therefore, the lower reinforcing member 9 is sandwiched between the driver's seat side door panel 2a and the center tunnel 12, so that the rotation of the upper reinforcing member 9 can also be effectively prevented, and the input load can be reduced. 10 can effectively share the load and effectively distribute the load.
[0031]
[Modification]
In the above embodiment, the upper reinforcing member 9 and the lower reinforcing member 10 are connected by the inner bracket 13 and the outer bracket 14 near their inner ends 9a, 10a and near their outer ends 9b, 10b. As shown in FIG. 4, the inner bracket and the outer bracket may be the seat back frames 8.
[0032]
That is, the seat back frame 8 itself is used as an inner bracket and an outer bracket for connecting the reinforcing members 9, 10, and the reinforcing members 9, 10 are provided near the inner ends 9a, 10a and near the outer ends 9b, 10b. It is directly attached to the seat back 8. Accordingly, it is not necessary to separately prepare an inner bracket and an outer bracket as connecting members, which can contribute to reduction in the number of parts, manufacturing cost, and weight of the vehicle 1.
[0033]
Further, the upper reinforcing member 9, the lower reinforcing member 10, and the seat back frame 8 may be integrally formed. Thereby, the number of parts can be further reduced.
[0034]
【The invention's effect】
As described above, according to the invention according to the claims of the present application, since the two reinforcing members are connected by the side connecting members near the side end portions of the upper reinforcing member and the lower reinforcing member on the side of the passenger compartment, the vehicle However, even when a load is input from a high position on the side surface, the upper reinforcing member does not rotate around the center end independently of the lower reinforcing member. Therefore, both reinforcement members can share the input load, and the input load can be effectively dispersed.
