Abstract
An emergency evacuation slide has an internal energy dissipation characteristic so that the slide is especially suitable for evacuation of persons from a relatively great height. By dissipating the energy internally in the slide rather than by frictional heating of the clothing and skin of the evacuating persons, the danger of skin burns and other injuries to the persons is reduced or avoided. The slide surface of the slide is made up of a plurality of slide modules that each include an elastically elongatable segment, an interconnecting segment, and an anti-slip segment, which are respectively connected together one after another. The anti-slip segment has an upper anti-slip surface with a high coefficient of friction so that the anti-slip segment remains in static frictional contact and moves along with the evacuating person. The bottom surface of the anti-slip segment has a predefined coefficient of friction. The upstream end of the elongatable segment and the downstream end of the anti-slip segment are connected mechanically to a slide support body. As a person slides down the slide, the anti-slip segment moves downward along with the person and the downstream end thereof curls or rolls under itself, while the elongatable segment stretches elastically. Energy is dissipated by internal friction within the elastic elongatable segment and by friction of the bottom surface of the anti-slip segment curling or rolling under itself.
