PROBLEM TO BE SOLVED: To provide a vehicle door reinforcement device capable of expanding a door opening while achieving both improvement of rigidity against a collision load and suppression of enlargement and mass increase of a load transmission member.SOLUTION: A vehicle door reinforcement device 10 comprises a front side door 20 having a load transmission member 20D, a first reinforcement member 24, a second reinforcement member 26, an actuator 32, a collision detection part, and a control part. The first reinforcement member 24 is provided at a vehicle front side of one end part 20D1 of the load transmission member 20D in a longitudinal direction so as to be apart from the load transmission member 20D on a vehicle width direction inner side, and reinforces a vehicle body. The second reinforcement member 26 can take either a first state of projecting outward in the vehicle width direction from the first reinforcement member 24 and a second state of inclining to the vehicle rear side with respect to the first reinforcement member 24. In the second state, a projection-direction tip part of the second reinforcement member 26 supports the one end part 20D1 of the load transmission member 20D.SELECTED DRAWING: Figure 1
【課題】衝突荷重に対する剛性の向上と荷重伝達部材の大型化及び質量増加の抑制とを両立させて、ドア開口を拡げることができる車両用ドア補強装置を提供する。【解決手段】車両用ドア補強装置10は、荷重伝達部材20Dを有するフロントサイドドア20と、第1補強部材24と、第2補強部材26と、アクチュエータ32と、衝突検知部と、制御部とを備えている。第1補強部材24は、荷重伝達部材20Dの長手方向一端部20D1よりも車両前方側において、荷重伝達部材20Dよりも車両幅方向内側に離間して設けられ、車体を補強する。第2補強部材26は、第1補強部材24から車両幅方向外側に突出された第1状態と、第1補強部材24に対して車両後方側へ傾斜する第2状態のいずれの状態になり得る。第2状態において、第2補強部材26の突出方向先端部は荷重伝達部材20Dの一端部20D1を支持する構成とされている。【選択図】図1
