To provide a knee bolster which makes it possible to perform relaxation of impact stably.SOLUTION: A knee bolster 10 comprises: an accommodation apparatus 11 which releases impact shock against a knee H by compression failure of a rigid polyurethane foam 40 by taking the knee H of an occupant J at collision of a vehicle 90 and accommodates the rigid polyurethane foam 40; a first vessel constitution part 20 which constitutes a part of the accommodation apparatus 11 and is fixed to the vehicle 90; a second vessel constitution part 30 which constitutes the other part of the accommodation apparatus 11 and opposes in a compression direction of the rigid polyurethane foam 40 by interposing the rigid polyurethane foam 40 with respect to the first vessel constitution part 20; and a movement regulation part which allows movement to the compression direction of the second vessel constitution part 30 and regulates movement to a direction intersecting with the compression direction.SELECTED DRAWING: Figure 3
【課題】衝撃の緩和を安定して行うことが可能なニーボルスタの提供。【解決手段】ニーボルスタ10は、車両90の衝突時に乗員Jの膝Hを受け止めて、硬質ポリウレタンフォーム40の圧縮破壊によって膝Hへの衝撃を緩和し、硬質ポリウレタンフォーム40を収容する収容器11と、収容器11の一部を構成し、車両90に固定される第1容器構成部20と、収容器11の他の一部を構成し、第1容器構成部20に対して硬質ポリウレタンフォーム40を間に挟んで硬質ポリウレタンフォーム40の圧縮方向で対向する第2容器構成部30と、第2容器構成部30の前記圧縮方向への移動を許容しかつ前記圧縮方向と交差する方向への移動を規制する移動規制部と、を備える。【選択図】図3
