Description

本発明は、車両のドアに設けられ、車両の車室内に向けて突設する車両用アームレストに関する。 The present invention relates to a vehicle armrest provided on a vehicle door and projecting toward the vehicle interior of the vehicle.

従来、車両のドアに設けられる車両用アームレストが知られている（例えば特許文献１参照）。このような車両用アームレストは、車両の側面に対する衝突（以下、側突と記す）が発生したときに展開するサイドエアバッグによって押圧される。 Conventionally, a vehicle armrest provided on a vehicle door is known (see, for example, Patent Document 1). Such a vehicle armrest is pressed by a side airbag that deploys when a collision with the side surface of the vehicle (hereinafter referred to as a side collision) occurs.

特許文献１の車両用アームレストは、車両のドアの車室内側に固定されるドアトリムから車室内側に向けて突出して形成される。また、特許文献１の車両用アームレストは、上面を有し、上面の裏側に強度を低減させる３条の溝部が形成される。特許文献１の車両用アームレストは、サイドエアバッグから押圧されることによって、この溝部が潰れる。このように溝部が潰れることで、車両用アームレストが変形し、着座している乗員とアームレストの間にスペースが生まれる。 The vehicle armrest of Patent Document 1 is formed so as to project toward the vehicle interior side from a door trim fixed to the vehicle interior side of the vehicle door. Further, the vehicle armrest of Patent Document 1 has an upper surface, and three grooves for reducing strength are formed on the back side of the upper surface. The groove portion of the vehicle armrest of Patent Document 1 is crushed by being pressed from the side airbag. By crushing the groove in this way, the armrest for the vehicle is deformed, and a space is created between the seated occupant and the armrest.

特許文献１の車両用アームレストでは、３条の溝部は、サイドエアバッグが展開した場合、サイドエアバッグが押圧する部位からの距離が略均一になるように、車室外側に向けて、中央部が膨らんだ曲線状に形成される。しかし、車両が側突した場合、ドアは変形するため、サイドエアバッグが押圧する部位は必ずしも一定ではない。このため、特許文献１の車両用アームレストでは、溝部が潰れず、車両用アームレストが変形しないおそれがある。 In the vehicle armrest of Patent Document 1, the three groove portions are centrally directed toward the outside of the vehicle interior so that when the side airbag is deployed, the distance from the portion pressed by the side airbag is substantially uniform. Is formed in a bulging curved shape. However, when the vehicle collides with the side, the door is deformed, so that the portion pressed by the side airbag is not always constant. Therefore, in the vehicle armrest of Patent Document 1, the groove portion may not be crushed and the vehicle armrest may not be deformed.

また、車両用アームレストは、乗員の腕を支える機能がある。このため、車両用アームレストは、乗員の腕が置かれた場合であっても車両用アームレストの上面が撓まないように、剛性が必要となる。 In addition, the vehicle armrest has a function of supporting the occupant's arm. Therefore, the vehicle armrest needs to be rigid so that the upper surface of the vehicle armrest does not bend even when the occupant's arm is placed.

本発明の課題は、剛性の低下を抑制しながら、車両が側突した場合に変形を促進可能な車両用アームレストを提供することにある。 An object of the present invention is to provide a vehicle armrest capable of promoting deformation when a vehicle collides sideways while suppressing a decrease in rigidity.

本発明に係る車両用アームレストは、車両のドアに設けられ、車両の車室内に向けて突設される車両用アームレストである。車両用アームレストは、ベース部と、第１貫通孔と、凹部と、を備える。ベース部は、車両の乗員の腕を支持可能な第１面と、第１面と反対側に形成される第２面と、を有し、車両用アームレストの基材となる。第１貫通孔は、ベース部に複数設けられ、車両の前後方向に延び、第１面から第２面まで貫通する。凹部は、第１貫通孔と車両の前後方向で隣り合った位置に設けられ、第１面または第２面の少なくともいずれか一方の面から他方の面に向けて切り欠いてなる。 The vehicle armrest according to the present invention is a vehicle armrest provided on a vehicle door and projected toward the vehicle interior of the vehicle. The vehicle armrest includes a base portion, a first through hole, and a recess. The base portion has a first surface capable of supporting the arm of the occupant of the vehicle and a second surface formed on the side opposite to the first surface, and serves as a base material for the armrest for the vehicle. A plurality of first through holes are provided in the base portion, extend in the front-rear direction of the vehicle, and penetrate from the first surface to the second surface. The recess is provided at a position adjacent to the first through hole in the front-rear direction of the vehicle, and is cut out from at least one surface of the first surface or the second surface toward the other surface.

この車両用アームレストによれば、例えば、車両が側突したときに展開するサイドエアバッグによって車両用アームレストが車幅方向に押圧された場合、第１貫通孔によって車両用アームレストが車幅方向に狭まる変形が促進される。第１貫通孔によって車両用アームレストの変形が促進されると、第１貫通孔と隣り合った凹部に圧力が作用し、作用した圧力によって凹部付近が剪断される。この結果、車両用アームレストの変形が促進される。一方、凹部は第１貫通孔よりも剛性が高く、第１貫通孔に隣り合って凹部を設けることで、車両用アームレストの剛性の低下が抑制できる。これによって、第１面で乗員の腕を支持する場合、第１面が撓むことを防止できる。すなわち、この構成によれば、剛性の低下を抑制しながら、車両が側突した場合に変形を促進可能な車両用アームレストを提供できる。 According to this vehicle armrest, for example, when the vehicle armrest is pressed in the vehicle width direction by a side airbag deployed when the vehicle collides sideways, the vehicle armrest is narrowed in the vehicle width direction by the first through hole. Deformation is promoted. When the deformation of the vehicle armrest is promoted by the first through hole, pressure acts on the recess adjacent to the first through hole, and the pressure applied causes the vicinity of the recess to be sheared. As a result, the deformation of the vehicle armrest is promoted. On the other hand, the recess has a higher rigidity than the first through hole, and by providing the recess adjacent to the first through hole, it is possible to suppress a decrease in the rigidity of the vehicle armrest. This makes it possible to prevent the first surface from bending when the occupant's arm is supported by the first surface. That is, according to this configuration, it is possible to provide a vehicle armrest capable of promoting deformation when the vehicle collides sideways while suppressing a decrease in rigidity.

凹部は、傾斜部を有してもよい。傾斜部は、凹部の最深部から凹部が設けられた面の切り欠きが形成された起点に向けて傾斜してもよい。 The recess may have an inclined portion. The inclined portion may be inclined from the deepest portion of the recess toward the starting point where the notch of the surface provided with the recess is formed.

この構成によれば、車両用アームレストの変形が促進されると、作用した圧力によって凹部付近が剪断される。凹部付近が剪断されると、剪断された部分の一端が、傾斜部に乗り上げる。一端が傾斜部に乗り上げると、凹部が設けられた面に向かって誘導される。この結果、車両用アームレストが車幅方向に狭まる変形がさらに円滑に行われる。 According to this configuration, when the deformation of the vehicle armrest is promoted, the vicinity of the recess is sheared by the applied pressure. When the vicinity of the recess is sheared, one end of the sheared portion rides on the inclined portion. When one end rides on the inclined portion, it is guided toward the surface provided with the recess. As a result, the vehicle armrest is deformed to be narrowed in the vehicle width direction more smoothly.

凹部は、第１凹部と、第２凹部と、を含んでもよい。第１凹部は、第１傾斜部を有してもよい。第２凹部は、第２傾斜部を有してもよい。第１傾斜部は、第１凹部の最も深い位置である第１最深部から一方の第１面の切り欠きが形成される起点に向かって傾斜してもよい。第２傾斜部は、第２凹部の最も深い位置である第２最深部から他方の第２面の切り欠きが形成される起点に向かって傾斜してもよい。 The recess may include a first recess and a second recess. The first recess may have a first inclined portion. The second recess may have a second inclined portion. The first inclined portion may be inclined from the first deepest portion, which is the deepest position of the first recess, toward the starting point where the notch of one first surface is formed. The second inclined portion may be inclined from the second deepest portion, which is the deepest position of the second recess, toward the starting point where the notch of the other second surface is formed.

この構成によれば、凹部付近の剪断された部分の一端が第１傾斜部または第２傾斜部に乗り上げる。また、凹部付近の剪断された部分の他端は、第１傾斜部または第２傾斜部のうち一端が乗り上げた傾斜部と異なる傾斜部に接する。これによって、凹部付近の剪断された部分の一端および他端の双方が第１傾斜部および第２傾斜部によって誘導される。また、第１傾斜部と第２傾斜部は、一方向に向けて形成される。これにより、第１傾斜部および第２傾斜部の双方が引っ掛かることなく、円滑に凹部付近の剪断された部分の一端および他端を誘導できる。この結果、車両用アームレストが車幅方向に狭まる変形がさらに円滑に行われる。 According to this configuration, one end of the sheared portion near the recess rides on the first inclined portion or the second inclined portion. Further, the other end of the sheared portion near the recess is in contact with an inclined portion of the first inclined portion or the second inclined portion, which is different from the inclined portion on which one end rides. As a result, both one end and the other end of the sheared portion near the recess are guided by the first inclined portion and the second inclined portion. Further, the first inclined portion and the second inclined portion are formed in one direction. As a result, one end and the other end of the sheared portion in the vicinity of the recess can be smoothly guided without both the first inclined portion and the second inclined portion being caught. As a result, the vehicle armrest is deformed to be narrowed in the vehicle width direction more smoothly.

第１凹部は、第１壁部を有してもよい。第２凹部は、第２壁部を有してもよい。第１壁部は、第１最深部から第１傾斜部と異なる方向に延びてもよい。第２壁部は、第２最深部から第２傾斜部と異なる方向に延びてもよい。第１壁部と第２壁部は、車幅方向の断面視で一直線上に設けられてもよい。第１最深部は、第２最深部よりも第１面側に設けられてもよい。第２最深部は、第１最深部よりも第２面側に設けられてもよい。 The first recess may have a first wall portion. The second recess may have a second wall portion. The first wall portion may extend from the first deepest portion in a direction different from that of the first inclined portion. The second wall portion may extend from the second deepest portion in a direction different from that of the second inclined portion. The first wall portion and the second wall portion may be provided in a straight line in a cross-sectional view in the vehicle width direction. The first deepest portion may be provided on the first surface side with respect to the second deepest portion. The second deepest portion may be provided on the second surface side of the first deepest portion.

この構成によれば、例えば、車両が側突したときに展開するサイドエアバッグによって車両用アームレストが車幅方向に押圧された場合、圧力が第１壁部および第１傾斜部を伝わって第１最深部に集中する。同様に、圧力は第２壁部および第２傾斜部を伝わって第２最深部に集中する。また、第１最深部は、第２最深部よりも第１面側にあり、第２最深部は、第１最深部よりも第２面側にあるため、第１最深部と第２最深部との間が他の部分に比べて薄肉となる。第１最深部および第２最深部に集中した圧力は、この薄肉の凹部付近を剪断する方向に作用する。このとき、第１壁部と、第２壁部は、車幅方向の断面視で一直線上に設けられるため、剪断する距離が短い。これによって、凹部付近は剪断されやすい。一方、車両用アームレストが車幅方向に押圧されていない場合、第１最深部と第２最深部との間の他の部分に比べて薄肉となる部分によって、車両用アームレストの剛性の低下がさらに抑制できる。 According to this configuration, for example, when the vehicle armrest is pressed in the vehicle width direction by a side airbag that is deployed when the vehicle collides sideways, the pressure is transmitted through the first wall portion and the first inclined portion to be the first. Focus on the deepest part. Similarly, the pressure is transmitted through the second wall portion and the second inclined portion and concentrated in the second deepest portion. Further, since the first deepest portion is on the first surface side of the second deepest portion and the second deepest portion is on the second surface side of the first deepest portion, the first deepest portion and the second deepest portion are located. The space between and is thinner than the other parts. The pressure concentrated on the first deepest part and the second deepest part acts in the direction of shearing the vicinity of the thin-walled recess. At this time, since the first wall portion and the second wall portion are provided in a straight line in the cross-sectional view in the vehicle width direction, the shearing distance is short. As a result, the vicinity of the recess is easily sheared. On the other hand, when the vehicle armrest is not pressed in the vehicle width direction, the rigidity of the vehicle armrest is further reduced due to the portion thinner than the other portion between the first deepest portion and the second deepest portion. Can be suppressed.

ドアの車室内側には、ドアトリムが設けられてもよい。車両用アームレストは、ベース部に設けられ、ベース部をドアトリムに取り付けるボス部をさらに備えてもよい。ボス部は、第１面の上面視で第１貫通孔と車幅方向に見て重なる位置に設けられてもよい。 A door trim may be provided on the vehicle interior side of the door. The vehicle armrest may be further provided with a boss portion that is provided on the base portion and attaches the base portion to the door trim. The boss portion may be provided at a position where it overlaps with the first through hole when viewed from above on the first surface in the vehicle width direction.

この構成によれば、ボス部からの入力が第１貫通孔に伝わりやすい。これによって、車幅方向の変形がさらに促進されやすい。 According to this configuration, the input from the boss portion is easily transmitted to the first through hole. As a result, deformation in the vehicle width direction is more likely to be promoted.

第１貫通孔および凹部のいずれか一つは、上面の車幅方向の中央線を通ってもよい。 Any one of the first through hole and the recess may pass through the center line in the vehicle width direction of the upper surface.

この構成によれば、第１貫通孔および凹部のいずれか一つは、上面の車幅方向の中央線を通る。中央線は、サイドエアバッグから受ける圧力がかかる位置と、ドアトリムから受ける圧力がかかる位置の略中央である。このため、第１貫通孔および凹部のいずれか一つは車室内側からの圧力と、車室外側からの圧力を同時に受ける。これによって、アームレストの変形がさらに促進されやすい。 According to this configuration, any one of the first through hole and the recess passes through the center line in the vehicle width direction of the upper surface. The center line is approximately the center of the position where the pressure received from the side airbag is applied and the position where the pressure received from the door trim is applied. Therefore, any one of the first through hole and the recess receives the pressure from the passenger compartment side and the pressure from the passenger compartment outside at the same time. As a result, the deformation of the armrest is more likely to be promoted.

車両用アームレストは、第２貫通孔をさら備えてもよい。第２貫通孔は、ベース部に設けられ、車両の車幅方向に延び、第１面から第２面までを貫通してもよい。第２貫通孔は、第１貫通孔と、凹部との間に設けられてもよい。 The vehicle armrest may be further provided with a second through hole. The second through hole may be provided in the base portion, extend in the vehicle width direction of the vehicle, and penetrate from the first surface to the second surface. The second through hole may be provided between the first through hole and the recess.

この構成によれば、第２貫通孔が車幅方向に潰れることで、第１貫通孔および凹部に圧力が伝達しやすい。 According to this configuration, the pressure is easily transmitted to the first through hole and the recess by crushing the second through hole in the vehicle width direction.

本発明によれば、剛性の低下を抑制しながら、車両が側突した場合に変形を促進可能な車両用アームレストを提供できる。 According to the present invention, it is possible to provide a vehicle armrest capable of promoting deformation when a vehicle collides sideways while suppressing a decrease in rigidity.

That is, the first inclined portion 28a and the second inclined portion 28b are formed in the same direction to form planes parallel to each other.

第１凹部１６ａは、第１壁部３２ａを有する。第２凹部１６ｂは、第２壁部３２ｂを有する。第１壁部３２ａは、第１最深部３０ａから第１傾斜部２８ａと異なる方向に延びる。本実施形態では、第１壁部３２ａは、上面２４と垂直となるように第１最深部３０ａから延びる。すなわち第１凹部１６ａは、第１壁部３２ａと上面２４となす角度が直角である直角三角形の形状である。 The first recess 16a has a first wall portion 32a. The second recess 16b has a second wall portion 32b. The first wall portion 32a extends from the first deepest portion 30a in a direction different from that of the first inclined portion 28a.

That is, the shape of the second recess 16b coincides with the point-symmetrical shape of the first recess 16a with respect to the midpoint between the upper surface 24 and the lower surface 26 on the vertical line X2.

ボス部１８は、図３に示すように、ベース部１０をドアトリム２に取り付けるために設けられる。より具体的には、ドアトリム２には、ボス部１８を挿通可能な挿通穴（図示せず）が設けられ、この挿通穴にボス部１８を挿通させて固定することで、ドアトリム２にベース部１０が固定され取り付けられる。ボス部１８は、図３の拡大図に示すように、上面２４の上面視で第１貫通孔１２と車幅方向Ｐに重なる位置に設けられる。 As shown in FIG. 3, the boss portion 18 is provided for attaching the base portion 10 to the door trim 2. More specifically, the door trim 2 is provided with an insertion hole (not shown) through which the boss portion 18 can be inserted, and by inserting and fixing the boss portion 18 through the insertion hole, the base portion is inserted into the door trim 2. 10 is fixed and attached. As shown in the enlarged view of FIG. 3, the boss portion 18 is provided at a position overlapping the first through hole 12 in the vehicle width direction P in the top view of the upper surface 24.

薄肉部２０は、図４に示すように、上面２４または下面２６のうち凹部１６の設けられた面と反対側の面との間に形成される。本実施形態では、薄肉部２０は、第１凹部１６ａと下面２６の間、および、第２凹部１６ｂと上面２４の間に形成される。薄肉部２０は、上面２４と下面２６との間に挟まれた支持部１０ａを形成する肉部３４の厚さよりも、厚さが薄い領域であり、凹部１６の、ドアトリム２側の端部１６ｃから車室内側の端部１６ｃまでの間の領域である。また、本実施形態では、第１壁部３２ａと、第２壁部３２ｂは、上面２４および下面２６の鉛直線Ｘ２（一直線の一例）上に設けられるため、第１最深部３０ａと、第２最深部３０ｂと、の間の薄肉部２０の厚みが最も薄い。 As shown in FIG. 4, the thin-walled portion 20 is formed between the surface of the upper surface 24 or the lower surface 26 where the recess 16 is provided and the surface on the opposite side. In the present embodiment, the thin portion 20 is formed between the first recess 16a and the lower surface 26, and between the second recess 16b and the upper surface 24. The thin portion 20 is a region thinner than the thickness of the meat portion 34 forming the support portion 10a sandwiched between the upper surface 24 and the lower surface 26, and is the end portion 16c of the recess 16 on the door trim 2 side. It is a region from to the end portion 16c on the vehicle interior side. Further, in the present embodiment, since the first wall portion 32a and the second wall portion 32b are provided on the vertical straight line X2 (an example of a straight line) of the upper surface 24 and the lower surface 26, the first deepest portion 30a and the second The thickness of the thin portion 20 between the deepest portion 30b and that of the thin portion 20 is the thinnest.

このように構成された車両用アームレスト１は、図３に示すように、車両Ｃに側突が発生した場合、ドア４が車室内側へ変形することで発生する車室内側への押圧を受ける。また、車両用アームレスト１は、サイドエアバッグ８が展開することで発生するドアトリム２側への押圧を受ける。すなわち、車両用アームレスト１は、車幅方向Ｐにドアトリム２側および車室内側の双方から押圧される。このとき、ボス部１８はドアトリム２から押圧を受け、上面２４の上面視で車幅方向Ｐに重なる位置に設けられた第１貫通孔１２を押圧する。また、第１貫通孔１２は、サイドエアバッグ８からも押圧を受ける。第１貫通孔１２は中央線Ｘ１を通り、中央線Ｘ１は、サイドエアバッグ８から受ける圧力がかかる位置と、ドアトリム２から受ける圧力が作用する位置の略中央である。このため、第１貫通孔１２は、車室内側からの圧力とドアトリム２側（車室外側）からの圧力を同時に受け、車幅方向Ｐに狭まる変形が発生する。第２貫通孔１４も同様に、車幅方向Ｐに狭まる変形が発生する。 As shown in FIG. 3, the vehicle armrest 1 configured in this way receives pressure on the vehicle interior side generated by the door 4 being deformed toward the vehicle interior side when a side collision occurs in the vehicle C. .. Further, the vehicle armrest 1 receives the pressure on the door trim 2 side generated by the deployment of the side airbag 8. That is, the vehicle armrest 1 is pressed from both the door trim 2 side and the vehicle interior side in the vehicle width direction P. At this time, the boss portion 18 receives pressure from the door trim 2 and presses the first through hole 12 provided at a position overlapping in the vehicle width direction P in the upper surface view of the upper surface 24. The first through hole 12 is also pressed by the side airbag 8. The first through hole 12 passes through the center line X1, and the center line X1 is substantially the center of the position where the pressure received from the side airbag 8 is applied and the position where the pressure received from the door trim 2 acts. Therefore, the first through hole 12 receives the pressure from the vehicle interior side and the pressure from the door trim 2 side (outside the vehicle interior) at the same time, and the first through hole 12 is deformed to narrow in the vehicle width direction P. Similarly, the second through hole 14 also undergoes deformation that narrows in the vehicle width direction P.

第１貫通孔１２および第２貫通孔１４が車幅方向Ｐに狭まる変形が発生すると、凹部１６に圧力が作用する。すなわち、図４の上段（ａ）に示すように、圧力が第１壁部３２ａおよび第１傾斜部２８ａを伝わって第１最深部３０ａに集中する。同様に、圧力は第２壁部３２ｂおよび第２傾斜部２８ｂを伝わって第２最深部３０ｂに集中する。第１最深部３０ａおよび第２最深部３０ｂに集中した圧力は、薄肉部２０のうち最も薄くなる、第１最深部３０ａおよび第２最深部３０ｂの間を剪断する方向に作用する。第１壁部３２ａと、第２壁部３２ｂは、車幅方向Ｐの断面視で鉛直線Ｘ２上に設けられるため、剪断する距離が短く、薄肉部２０は剪断されやすい。 When the first through hole 12 and the second through hole 14 are deformed to narrow in the vehicle width direction P, pressure acts on the recess 16. That is, as shown in the upper part (a) of FIG. 4, the pressure is transmitted through the first wall portion 32a and the first inclined portion 28a and concentrated on the first deepest portion 30a. Similarly, the pressure is transmitted through the second wall portion 32b and the second inclined portion 28b and concentrated on the second deepest portion 30b. The pressure concentrated on the first deepest portion 30a and the second deepest portion 30b acts in the direction of shearing between the first deepest portion 30a and the second deepest portion 30b, which is the thinnest of the thin-walled portions 20. Since the first wall portion 32a and the second wall portion 32b are provided on the vertical line X2 in the cross-sectional view in the vehicle width direction P, the shearing distance is short and the thin wall portion 20 is easily sheared.

薄肉部２０が剪断されると、図４の下段（ｂ）に示すように、剪断された部分の一端４０が、第１傾斜部２８ａに乗り上げる。一方、剪断された部分の他端４２は、第２傾斜部２８ｂに接した状態となる。このような状態で、一端４０および他端４２の双方が第１傾斜部２８ａおよび第２傾斜部２８ｂによって端部１６ｃに向けて誘導される。また、本実施形態では、第１傾斜部２８ａと、第２傾斜部２８ｂは、同一方向に形成されるため、第１傾斜部２８ａおよび第２傾斜部２８ｂの双方が引っ掛かることなく、円滑に一端４０および他端４２を端部１６ｃに向けて誘導できる。この結果、車両用アームレスト１は、車両Ｃが側突した場合に車両用アームレスト１が車幅方向Ｐに狭まる変形を促進できる。 When the thin portion 20 is sheared, one end 40 of the sheared portion rides on the first inclined portion 28a as shown in the lower part (b) of FIG. On the other hand, the other end 42 of the sheared portion is in contact with the second inclined portion 28b. In such a state, both one end 40 and the other end 42 are guided toward the end portion 16c by the first inclined portion 28a and the second inclined portion 28b. Further, in the present embodiment, since the first inclined portion 28a and the second inclined portion 28b are formed in the same direction, both the first inclined portion 28a and the second inclined portion 28b are smoothly formed at one end without being caught. The 40 and the other end 42 can be guided toward the end 16c. As a result, the vehicle armrest 1 can promote deformation in which the vehicle armrest 1 narrows in the vehicle width direction P when the vehicle C collides sideways.

一方、車両用アームレスト１が車幅方向Ｐに押圧されていない場合、第１最深部３０ａと第２最深部３０ｂとの間の薄肉部２０によって、車両用アームレスト１の剛性の低下が抑制できる。これによって、車両用アームレスト１は、上面２４の撓みを抑制できる。 On the other hand, when the vehicle armrest 1 is not pressed in the vehicle width direction P, the thin portion 20 between the first deepest portion 30a and the second deepest portion 30b can suppress a decrease in the rigidity of the vehicle armrest 1. As a result, the vehicle armrest 1 can suppress the bending of the upper surface 24.

以上説明した通り、本発明の第１実施形態によれば、剛性の低下を抑制しながら、車両Ｃが側突した場合に変形を促進可能な車両用アームレスト１を提供できる As described above, according to the first embodiment of the present invention, it is possible to provide a vehicle armrest 1 capable of promoting deformation when the vehicle C collides sideways while suppressing a decrease in rigidity.

＜第２実施形態＞
次に、本発明の第２実施形態について、図５を用いて説明する。なお、以下の説明においては、第１実施形態の車両用アームレスト１と異なる点のみ説明する。 <Second Embodiment>
Next, the second embodiment of the present invention will be described with reference to FIG. In the following description, only the differences from the vehicle armrest 1 of the first embodiment will be described.

第２実施形態の車両用アームレスト２０１では、図５の上段（ａ）に示すように、第１傾斜部２２８ａは、第１凹部２１６ａの最も深い位置である第１最深部２３０ａから、第１凹部２１６ａが設けられた上面２２４に向かって車幅方向Ｐのドアトリム２側にある端部２１６ｃ（第２実施形態における起点の一例）まで傾斜する。すなわち、第１凹部２１６ａは、上面２２４から下面２２６に向けて切り欠いてなる。凹部２１６の車幅方向Ｐのドアトリム２側にある端部２１６ｃは、上面２２４の切り欠きである第１凹部２１６ａが形成される起点である。また、図５の上段（ａ）に拡大して示すように、第２傾斜部２２８ｂは、第２凹部２１６ｂの最も深い位置である第２最深部２３０ｂから第２凹部２１６ｂが設けられた下面２２６に向かって車室内側にある端部２１６ｃ（第２実施形態における起点の一例）まで傾斜する。すなわち、第２凹部２１６ｂは、下面２２６から上面２２４に向けて切り欠いてなる。凹部２１６の車幅方向Ｐの車室内側にある端部２１６ｃは、下面２２６の切り欠きである第２凹部２１６ｂが形成される起点である。 In the vehicle armrest 201 of the second embodiment, as shown in the upper part (a) of FIG. 5, the first inclined portion 228a is from the first deepest portion 230a, which is the deepest position of the first concave portion 216a, to the first concave portion. It is inclined toward the upper surface 224 provided with 216a to the end portion 216c (an example of the starting point in the second embodiment) on the door trim 2 side in the vehicle width direction P. That is, the first recess 216a is cut out from the upper surface 224 to the lower surface 226. The end portion 216c of the recess 216 on the door trim 2 side in the vehicle width direction P is a starting point at which the first recess 216a, which is a notch on the upper surface 224, is formed. Further, as shown in an enlarged manner in the upper part (a) of FIG. 5, the second inclined portion 228b is a lower surface 226 provided with the second deepest portion 230b to the second concave portion 216b, which is the deepest position of the second concave portion 216b. It inclines toward the end 216c (an example of the starting point in the second embodiment) on the vehicle interior side. That is, the second recess 216b is cut out from the lower surface 226 toward the upper surface 224. The end 216c of the recess 216 on the vehicle interior side in the vehicle width direction P is a starting point at which the second recess 216b, which is a notch on the lower surface 226, is formed.

すなわち、第１凹部２１６ａには、車幅方向Ｐの車室内側へ向かうほど深くなる斜面が形成され、第２凹部２１６ｂには、車幅方向Ｐのドアトリム２側へ向かうほど深くなる斜面が形成される。 That is, the first recess 216a is formed with a slope that becomes deeper toward the vehicle interior side in the vehicle width direction P, and the second recess 216b is formed with a slope that becomes deeper toward the door trim 2 side in the vehicle width direction P. Will be done.

このように構成された車両用アームレスト２０１では、車両Ｃに側突が発生した場合、薄肉部２２０が剪断されると、図５の下段（ｂ）に示すように、剪断された部分の一端２４０が、第２傾斜部２２８ｂに接する。一方、剪断された部分の他端２４２は、第１傾斜部２２８ａに乗り上げる。これによって、車両用アームレスト２０１が変形した場合、他端２４２がドアトリム２側に向けて移動する。このため、車室内にいる乗員に向けて他端２４２が突出することがない。この結果、車両Ｃが側突した場合に変形を促進可能でありながらも、車両用アームレスト２０１の変形によって突出物が発生することも抑制できる。 In the vehicle armrest 201 configured in this way, when a side collision occurs in the vehicle C, when the thin-walled portion 220 is sheared, one end 240 of the sheared portion is as shown in the lower part (b) of FIG. Is in contact with the second inclined portion 228b. On the other hand, the other end 242 of the sheared portion rides on the first inclined portion 228a. As a result, when the vehicle armrest 201 is deformed, the other end 242 moves toward the door trim 2 side. Therefore, the other end 242 does not protrude toward the occupant in the vehicle interior. As a result, while the deformation can be promoted when the vehicle C collides with the side, it is possible to suppress the generation of protrusions due to the deformation of the vehicle armrest 201.

以上説明した通り、本発明の第２実施形態によれば、剛性の低下を抑制しながら、車両Ｃが側突した場合に変形を促進可能でありながらも、変形による突出物の発生も抑制できる車両用アームレスト２０１を提供できる。 As described above, according to the second embodiment of the present invention, it is possible to promote deformation when the vehicle C collides sideways while suppressing a decrease in rigidity, and it is also possible to suppress the generation of protrusions due to deformation. A vehicle armrest 201 can be provided.
