Abstract: The system is based on the combination of two parts (1 and 1?) of differing densities with complementary tilted protuberances (2 and 2?), coupled to form a single unit. These protuberances vary in shape, length and thickness so that systems of differing rigidity can be obtained, thus achieving cushioning in virtue of the said protuberances (2 and 2?), enabling the path of the force applied to be defined, thus achieving optimum cushioning force. The system is applicable to both pressure cushioning systems (mattresses, pillows, seats, etc.) and impact cushioning systems (footwear, wheels, helmets, etc.).

Abstract: This is a body (1) that may become, for example, a mattress with one density or another, thickness and size, which has various housings or hollows (2) in an inclined arrangement, this same body (1) being able to present hollows or housings (2) with a different inclination, a different arrangement and different size and have inward protrusions (3) or side branches (4) to provide, in the first case, greater hardness to the area where the hollows (2) are located and in the second case, to provide greater softness to the area of the body (1) where the respective hollows or housings (2) are located, all of them, some or those corresponding to these areas or others, being able to incorporate a filling that may range from air under pressure to a filling of any kind of material, including reinforcements (11 and 11?) with more or less rigidity to provide the corresponding area greater or less strength.

Abstract: A system for protecting persons from impacts against road crash barriers in which the barrier rail has a curved upper part and has protuberances to absorb and decelerate the velocity of the vehicle or accident victim, and the posts supporting the barrier rail are provided with cladding formed of a number of concentric rings of variable thickness and made of material which deforms flexibly and recovers immediately which incorporates a housing designed to fit the post through pressure and a clamping effect in addition to any bar system.

Abstract: System for protecting persons from impacts against road crash barriers in which the barrier rail has a curved upper part to prevent cuts in the event of someone falling onto it and has protuberances to absorb and decelerate the velocity of the vehicle or accident victim, and the post (2) supporting the barrier rail is provided with cladding (5) formed of a number of concentric rings (6, 6?, 6?) of variable thickness and made of material which deforms flexibly and recovers immediately which incorporates a housing (7) designed to fit the post (2) through pressure and a clamping effect in addition to any bar system. The invention is useful for preventing injury and/or mutilation to motorists and cyclists.

Abstract: Improved system for absorbing impacts in motor vehicles consisting in coupling solidly to the vehicle body front beams which are intended to receive the impacts and deformable devices which are secured to the rear part of the body structure and which are intended to absorb strains. The front beams and the rear deformable devices are connected and hinged by a cable which is guided by a pulley provided at the front of the car; the pulley is characterized in that its support shaft is designed with a structure which can be progressively deformed longitudinally by the cable tension upon an impact with the aim to determine an appropriate displacement of the pulley towards the rear part of the vehicle, in accordance with its specific function.
