Abstract
A crash barrier for implementing a collision with a vehicle has a front to be moved toward the vehicle when the collision is implemented. The front side has a predetermined width and a predetermined height. The front side further has a selected surface region that takes up at most a 50% part of a width of the front side. A volume region of the crash barrier behind the surface region has a greater level of rigidity than a surrounding region of the crash barrier. Therefore, in the event of an impact against the vehicle, a greater level of rigidity acts in the selected surface region than in a surrounding region.
Claims14
A crash apparatus for implementing a collision situation with a vehicle, the crash apparatus comprising:
- a trolley movable toward the vehicle when the collision situation is implemented;
- a crash barrier extending in forward and rearward directions and having a front surface facing the vehicle and a rear surface opposite the front surface, the front surface having a width dimension and a height dimension, a high rigidity portion formed in the crash barrier and having a greater level of rigidity than adjacent regions of the crash barrier, the high rigidity portion extending in the forward and backward directions between the front and rear surfaces and including a forward-facing surface forming a portion of the front surface of the barrier, wherein
- a surface area of the forward-facing surface of the high rigidity portion is not more than 50% of a total surface area of the front surface.
A crash apparatus for implementing a collision situation with a vehicle, the crash apparatus comprising:
- a trolley movable toward the vehicle when the collision situation is implemented;
- a crash barrier extending in forward and rearward directions and having a front surface facing the vehicle and a rear surface opposite the front surface, the front surface having a width dimension and a height dimension, a high rigidity portion formed in the crash barrier and having a greater level of rigidity than adjacent regions of the crash barrier, the high rigidity portion extending in the forward and backward directions between the front and rear surfaces and including a forward-facing surface forming a portion of the front surface of the barrier, wherein
- the high rigidity portion has a first honeycomb structure, and adjacent regions of the crash barrier have a second honeycomb structure, and a size of the honeycombs of the first honeycomb structure is smaller than a size of the honeycombs of the second honeycomb structure.
