ABSTRACT:
A safety edge element made of flexible material includes a flat electric conductor, a rounded electric conductor as well as a first portion and a second portion. The first portion includes a base for the connection to a door or gate, a top with a seat to receive the flat electric conductor and two lateral sides to flexibly connect the base with the top. The base, top and lateral sides define a chamber. The second portion has a top and two lateral sides for the engagement with the top of the first portion and a seat arranged in the top of the second portion to receive the rounded electric conductor so that the rounded electric conductor is spaced from the flat electric conductor when the safety edge element is at rest and so that the rounded electric conductor is brought into contact with the flat conductor when the safety edge element experiences forces in orthogonal and inclined directions with respect to the base of the first portion.
