| 摘要 |
The present invention relates to a collapsible support ( 1 ) for absorbing energy during an impact, particularly to a support for an automobile knee bolster ( 50 ). The collapsible support ( 1 ) has the form of a tubular body with closed ends. The body extends along a longitudinal axis ( 3 ) along which it will collapse during an impact. The support ( 1 ) has two opposing end walls ( 4,10 ) substantially perpendicular to the axis ( 3 ). The two end walls ( 4,10 ) are connected by four similar stepped side walls ( 8 ) of rectangular plan form that substantially enclose the longitudinal axis ( 3 ) such that the side and end walls ( 8,4,10 ) of the collapsible support ( 1 ) substantially enclose an internal volume. The tubular body is adapted to deform so that sections ( 31-35 ) of side walls 8 collapse with one section moving inside another adjacent section upon the application of a compressive force applied to said body along said axis 3.
