本発明を実施するための最良の形態を添付図に基づいて以下に説明する。
図1は、本発明のロールオーバ保護装置(第1の実施の形態)を説明する図である。
第1の実施の形態のロールオーバ保護装置11は、車両12に採用したもので、助手席13に配置した車体支持部材14と、車体支持部材14に配置した緩衝部材15と、車両12の中央に配置した緩衝部材作動制御部16と、運転席に同様に配置した車体支持部材14と緩衝部材15を備える。17は車両12の制御装置、18は車両状況検出センサを示す。
The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a diagram for explaining a rollover protection device (first embodiment) according to the present invention.
The rollover protection device 11 according to the first embodiment is employed in a vehicle 12, and includes a vehicle body support member 14 disposed in a passenger seat 13, a buffer member 15 disposed in the vehicle body support member 14, and a center of the vehicle 12. And a vehicle body support member 14 and a buffer member 15 which are similarly arranged in the driver's seat. Reference numeral 17 denotes a control device for the vehicle 12, and 18 denotes a vehicle state detection sensor.

車両12は、屋根を開閉することができるコンバーチブルで、屋根を閉じた状態では、屋根の下方に緩衝部材15が展開する。なお、屋根は、樹脂製でもよく、金属製でもよい。   The vehicle 12 is a convertible that can open and close the roof. When the roof is closed, the buffer member 15 is deployed below the roof. The roof may be made of resin or metal.

車両状況検出センサ18は、車両12の横転や衝突を検出する既存のもので、仕様は任意である。
車体支持部材14は、助手席13の左右の下で且つ車体21に金属製の管22,22(図2参照)を固定した。
The vehicle condition detection sensor 18 is an existing sensor that detects a rollover or collision of the vehicle 12, and its specification is arbitrary.
The vehicle body support member 14 has metal pipes 22 and 22 (see FIG. 2) fixed to the vehicle body 21 below the left and right sides of the passenger seat 13.

図2は、本発明のロールオーバ保護装置(第1の実施の形態)の斜視図で、緩衝部材15を透視した状態で示した。
緩衝部材15は、車体支持部材14の頂部24に金属製のケース25を一体的に取付け、ケース25を樹脂製の装飾パネル26で覆い、ケース25及び装飾パネル26に開口蓋部27を形成し、ケース25内にインフレータ(ガス発生装置)31及びインフレータ(ガス発生装置)31の燃焼ガスで展開するエアバッグであるところのエアバッグ本体32を配置した。
FIG. 2 is a perspective view of the rollover protection device (first embodiment) according to the present invention, with the buffer member 15 seen through.
The buffer member 15 is integrally attached with a metal case 25 on the top 24 of the vehicle body support member 14, covers the case 25 with a resin decorative panel 26, and forms an opening lid portion 27 on the case 25 and the decorative panel 26. In the case 25, an inflator (gas generating device) 31 and an airbag main body 32 that is an airbag that is deployed with combustion gas of the inflator (gas generating device) 31 are arranged.

インフレータ(ガス発生装置)31は、既存のインフレータであり、例えば、助手席用としてインストルメントパネルに配置したインフレータとほぼ同様である。   The inflator (gas generating device) 31 is an existing inflator, and is substantially the same as an inflator disposed on an instrument panel for a passenger seat, for example.

ロールオーバ保護装置11を助手席13を対象に説明したが、当然、運転席にも同様(車体中心に対し対称)に車体支持部材14と緩衝部材15を配置した。   Although the rollover protection device 11 has been described for the passenger seat 13, the vehicle body support member 14 and the buffer member 15 are naturally arranged in the driver's seat as well (symmetrical with respect to the vehicle body center).

図3は、本発明のロールオーバ保護装置(第1の実施の形態)の横転時の作動状態を示す第1作用図である。
ロールオーバ保護装置(第1の実施の形態)11では、車両12が横転を始めると、乗員Mの上方でエアバッグ本体32が矢印a2,a2のように展開するので、車体支持部材14で乗員Mと地面Gとの間に空間を確保し、さらに、展開したエアバッグ本体32は乗員Mと地面Gとの間に介在し、乗員Mを受け止め、乗員Mに加わる衝撃を緩和することができる。
FIG. 3 is a first action diagram showing the operating state of the rollover protection device (first embodiment) of the present invention during rollover.
In the rollover protection device (first embodiment) 11, when the vehicle 12 starts to roll over, the airbag main body 32 is deployed above the occupant M as indicated by arrows a2 and a2. A space is secured between the M and the ground G, and the deployed airbag main body 32 is interposed between the occupant M and the ground G so that the occupant M can be received and the impact applied to the occupant M can be reduced. .

図4(a),(b)は、本発明のロールオーバ保護装置(第1の実施の形態)の第2作用図である。図1及び図2を併用して説明する。
具体的には、車両12が横転を始めると、車両状況検出センサ18の情報に基づいて、制御装置17は横転が起き始めたと判断し、制御装置17の横転情報に基づいて緩衝部材作動制御部16はインフレータ(ガス発生装置)31を作動させる。インフレータ(ガス発生装置)31は作動することで、燃焼ガスをエアバッグ本体32に吹込み、膨脹(広げる)させる。膨脹するエアバッグ本体32はケース25及び装飾パネル26に設定した開口蓋部27のティアラインを破断し、開口蓋部27を矢印a1のように開き、乗員Mの頭部H近傍であるところの上方の空間へ矢印a2,a2のように展開する。
4 (a) and 4 (b) are second operational views of the rollover protection device (first embodiment) of the present invention. This will be described with reference to FIGS.
Specifically, when the vehicle 12 starts to roll over, the control device 17 determines that rollover has started based on the information of the vehicle state detection sensor 18, and the buffer member operation control unit based on the rollover information of the control device 17. 16 operates an inflator (gas generator) 31. The inflator (gas generating device) 31 operates to inject combustion gas into the airbag main body 32 to inflate (expand). The inflating airbag body 32 breaks the tear line of the opening lid portion 27 set in the case 25 and the decorative panel 26, opens the opening lid portion 27 as indicated by an arrow a1, and is in the vicinity of the head H of the occupant M. Expands into the upper space as indicated by arrows a2 and a2.

このように、ロールオーバ保護装置11では、座席(助手席)13近傍の車体21に車体支持部材14を車両12の横転時(図3参照)に車体21を支持するように取付け、車体支持部材14に一体的に配置して乗員Mへの緩衝を図る緩衝部材15と、緩衝部材15の作動を車両12に配置した車両状況検出センサ18の情報に基づいて制御する緩衝部材作動制御部16と、を備えたので、車両12が横転を始めると、乗員Mの上方で緩衝部材15(エアバッグ本体32)が作動(展開)し、作動した緩衝部材15(エアバッグ本体32)は乗員Mと地面Gとの間に介在し、乗員Mを受け止め、乗員Mに加わる衝撃を緩和することができる。   Thus, in the rollover protection device 11, the vehicle body support member 14 is attached to the vehicle body 21 near the seat (passenger seat) 13 so as to support the vehicle body 21 when the vehicle 12 rolls over (see FIG. 3). 14 and a buffer member 15 for buffering the occupant M, and a buffer member operation control unit 16 for controlling the operation of the buffer member 15 based on information from a vehicle state detection sensor 18 disposed on the vehicle 12. When the vehicle 12 starts to roll over, the cushioning member 15 (airbag body 32) is activated (deployed) above the occupant M, and the actuated cushioning member 15 (airbag body 32) is connected to the occupant M. It is interposed between the ground G, the occupant M can be received, and the impact applied to the occupant M can be reduced.

また、ロールオーバ保護装置11では、乗員Mに対するシートベルトの拘束が十分でない場合にも、車外放出等による衝撃を低減することができる。   Further, the rollover protection device 11 can reduce the impact due to the release from the vehicle or the like even when the restraint of the seat belt on the occupant M is not sufficient.

さらに、ロールオーバ保護装置11では、緩衝部材15は、エアバッグ(エアバッグ本体)32であるから、緩衝部材15を速やかに展開することができる。   Furthermore, in the rollover protection device 11, since the buffer member 15 is an airbag (airbag body) 32, the buffer member 15 can be quickly deployed.

緩衝部材15は、車体支持部材14の頂部24に配置され、座席(助手席)13に座る乗員Mの頭部H近傍の空間へ展開するので、車体支持部材14で乗員Mの頭部Hと地面Gとの間に空間を確保し、さらに、展開した緩衝部材15(エアバッグ本体32)は乗員Mの頭部Hと地面Gとの間に介在し、乗員Mの頭部Hを受け止め、乗員Mの頭部Hに加わる衝撃を緩和することができる。   The buffer member 15 is disposed on the top 24 of the vehicle body support member 14 and expands into a space near the head H of the occupant M sitting on the seat (passenger seat) 13. A space is ensured between the ground G and the deployed cushioning member 15 (airbag body 32) is interposed between the head H of the occupant M and the ground G to receive the head H of the occupant M. The impact applied to the head H of the occupant M can be reduced.

次に本発明のロールオーバ保護装置の「別の実施の形態」を説明する。
