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: 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.
