<p>The invention relates to a movable barrier element (1), comprising a beam-shaped body provided on at least one outer end with connecting means (14,15) which are adapted to absorb kinetic energy, for instance when the body is rotated on at least one of its axes. For this purpose the connecting means comprise at least one deforming member manufactured from an elastic material (14,15), the stiffness of which is less than that of the beam-shaped body. The body further has a sloping end face (9,10) on its outer end and the deforming member is arranged on the sloping end face. The invention also relates to a movable barrier formed from a plurality of such barrier elements, which are mutually connected. Finally, the invention relates to a method for forming a movable barrier by placing a plurality of movable barrier elements one after another in lengthwise direction and mutually joining the elements by means of connecting means placed therebetween, wherein the connecting means are placed under bias. <IMAGE></p> |
