Shock absorbing device for use as e.g. safety element, during sporting practices, has envelope and spacer units deformed simultaneously, and side walls deformed simultaneously towards outer side according to folding line during deformation

摘要

The device (1) has an envelope (2) comprising side walls (5, 6) and opposite walls (3, 4) arranged parallel with each other, where the envelope is made of semi-rigid material. Elastic units (14) and spacer units are attached with each other to force the envelope in a non-compressed state of the device. The envelope and the spacer units are deformed simultaneously during the shock absorption of the envelope. The opposite walls are approached together and the side walls are deformed simultaneously toward an outer side according to a folding line (9) during the deformation.
