Title:
車両を減速させるためのケーブル・シリンダ構造体を備えた衝突減衰装置
Document Type and Number:
Japanese Patent JP2007502390
Kind Code:
A
Abstract:
An improved crash attenuator that uses a cable and shock arresting cylinder arrangement to control the rate at which a vehicle impacting the crash attenuator is decelerated to a safe stop is disclosed. The crash attenuator is comprised of a front section and a plurality of mobile sections with overlapping angular corrugated side panels. When the crash attenuator is impacted by a vehicle, the front section and mobile sections telescope down in response, and thus, are effectively longitudinally collapsed. For this purpose, the sections are slidably mounted on at least one guiderail that is attached to the ground. Positioned preferably between two guiderails is the cable and cylinder arrangement that exerts a force on the front section to resist the backward movement of the front section when struck by an impacting vehicle using a varying restraining force to control the rate at which an impacting vehicle is decelerated to safely stop the vehicle. The side panels can also be used in a guardrail configuration. A variety of transition arrangements to provide a smooth continuation from the crash attenuator to a fixed obstacle protected by the crash attenuator.
