Abstract: A guardrail defined by a number of vertical supporting posts fixed successively to the ground along the edge of a road, and by one or more longitudinal members fixed successively and substantially horizontally to the vertical posts to form a longitudinal transverse retaining member extending along the edge of the road, at a predetermined height off the ground; each of the longitudinal members being defined by a rigid, controlled-deformation strip of composite material, which is bent back on itself to form a substantially S-shaped first longitudinal portion and a substantially C-shaped second longitudinal portion adjoining and covering the first longitudinal portion, so as to form a tubular, complex-section body extending from one vertical post to another and substantially parallel to and a predetermined height off the ground.

Abstract: A guardrail terminal having a number of vertical supporting members fix into the ground one after the other along the edge of the road. The guardrail terminal, in certain embodiments, has a curved or straight first transverse horizontal retaining member fixed to the vertical supporting members at a given height off the ground, and curves in the horizontal plane so as to extend gradually away from the edge of the road. The guardrail terminal further may include a curled second transverse horizontal retaining member, which projects from the terminal end of the first transverse horizontal retaining member, curves back in the horizontal plane towards the first transverse horizontal retaining member, and is fixed by its own terminal end to the start end or to an intermediate portion of the first transverse horizontal retaining member, so as to form, together with the first transverse horizontal retaining member, a substantially tear-shaped collapsible annular member.

Abstract: A front impact damper having a vertical supporting member secured firmly to the ground, and a number of deformable tubular members fitted vertically inside one another and fixed to the vertical supporting member at a given height off the ground; the deformable tubular members each being defined by a portion of W- or triple-groove-section corrugated sheet metal bent appropriately to form a cylindrical tubular body with a corrugated lateral wall.

Abstract: A metallic guardrail barrier of the type comprising a sustaining post (1), a spacing member (2) extending parallel to the ground, secured at one side to the said sustaining post and carrying at the other side the rail (N), said spacing member being in the form of a substantially flat vertical plate (102) presenting a front portion (502) and a rear portion, in which the said spacing member (2) is connected to said sustaining post (1) by its rear portion so as to be swingable about a fulcrum (7) under the control of a shock absorbing means including a weakened region (9) on said rear portion of the spacing member at a location above and spaced from said fulcrum (7) and a pin (8) which connects said spacing member (2) and said sustaining post (1), and passes through said weakened portion (9), such that said pin (8) causes a tearing of said weakened region (9) when said rail (N) is impacted by a vehicle and said spacing member ( 2) moves about said fulcrum (7).

Abstract: A pre-skiing exercise device which permits body and leg movements similar to those performed when turning (Christiania-like) to the right and to the left during a downhill run. The device comprises two support bars (2) in parallel, side-by-side relation and arranged for attachment of ski-boots, either directly or through the respective ski (4). The rear sections of the support bars (2) slidably bear on an inverted V-shaped supporting cross member (6), and at an intermediate position on an articulated bar-supporting device (7), in which each of the bars (2) can rock independently of the other about an associated horizontal axis of inclination (X) transversal thereto, and both bars (2) can simultaneously perform concordant equal angular movements around associated upstanding axes of rotation (Y), which are vertical or preferably inclined rearwardly toward the inverted V rear supporting cross member (6).
