Embodiment Construction

[0038] The present invention will be further described in detail below through exemplary embodiments with reference to the accompanying drawings.

[0039] Reference attached figure 1 , which shows a safety device comprising a vehicle impact absorber according to the invention. The impact absorbing device is covered with a cover assembly 70 including a front cover 72 , a middle cover 71 and a rear cover 73 . Covers 71 , 72 and 73 are adapted to nest one over the other when (the impact absorber) is axially collapsed. The detailed design of the cover assembly 70 will be referred to hereinafter Figure 8 Be explained.

[0040] Figure 2 and Figure 4As shown in , the vehicle impact absorbing device includes a plurality of buffer units 30 arranged in an array. The buffer unit 30 absorbs vehicle impacts in a more efficient manner. Each buffer unit 30 has a slider 20 movably installed on a guide rail 10 fixed on the ground. The rail 10 has a set of bumper pins 40 fixed across t...

Abstract

A vehicular impact absorbing apparatus is disclosed. The apparatus includes a pair of tubular guide rails having a guide slit longitudinally formed at the upper part of each guide rail fixed to the ground. A plurality of sliders are movably mounted in the guide rail at a predetermined intervals, the upper part of each slider is laid on the upper part of the guide rail through the guide slit. A plurality of cushion units are mounted on the upper part of each slider. Each cushion unit is elastically deformed by vehicular impacts with retracting alongside the guide rail. A group of cushion pins are mounted across the guide rails at predetermined intervals between the sliders. The cushion pins also absorb the kinetic energy of an impact by being broken in turn by the slider that is retracting rearward. A stopper is installed around the rear end of the guide rail for stopping the retracting cushion units. A side fence is retractably mounted alongside the cushion units; the one end of the side fence is fixed to the stopper and the other to the front cushion unit. A successive cushion and deceleration of the impacts is possible in this arrangement.

Description

technical field [0001] The present invention relates to a safety device installed on a road where a vehicle impact may occur, and more particularly, to a vehicle impact absorbing device having a cushion pin which ensures effective absorption of the vehicle impact. Background technique [0002] Usually, various road safety features are installed (on the road), such as guardrails to prevent vehicles from leaving the road, and middle dividers to prevent vehicles from breaking into the opposite lane. In addition, there are safety devices or bumpers along the road in front of obstacles such as concrete walls, divider ends, toll booths, etc., to protect the obstacles from being hit by vehicles and to protect the safety of passengers in car accidents. [0003] Since it is set along the road, the guardrail and the middle divider rarely collide with the head-on of the vehicle. However, since the safety equipment is arranged in front of the direction of travel, it is easy to collide ...
