Claim 9:
10. An impact absorbing mat adapted to be placed on a surface for decelerating and absorbing an impact of a user falling thereon, the mat comprising:
a top surface having a generally planar configuration, said top surface being supported to receive the impact of the user falling at a velocity thereon, and to deform downwardly from the generally planar configuration by one or more baffles each configured to undergo compression and to change from a respective original uncompressed shape in which the top surface supported thereon has the generally planar configuration to a respective compressed shape in response to the impact of the user in which the top surface is deformed downwardly, and to return to the original uncompressed shape when the compression from the impact or weight of the user is no longer present, so that the top surface returns to the generally planar configuration, wherein the impact absorbing device can receive and decelerate and absorb subsequent further impacts;
wherein the one or more baffles each includes
one or more air outlet/inlets each having an aperture that is open and allows air to flow out of the baffle at all times, said aperture being configured to restrict air displacement flowing out of each baffle when the baffle is compressed by the impact, and
content material in each baffle that absorbs energy of the impact;
wherein, upon compression of the one or more baffles, air flows out thereof through the aperture with pressure in the one or more baffles being increased as a result of restriction of air displacement from the air outlet/inlets and the content material in the one or more baffles upon the compression of the one or more baffles; and
wherein air flows out of the one or more baffles through the aperture until pressure in the one or more baffles reaches ambient pressure around the mat;
wherein increased pressure in the one or more baffles causes compression resistance of the one or more baffles to the deformation downward of the top layer by causing the one or more baffles to exert a force that decelerates the user; and
wherein the one or more baffles includes one or more cells formed of the content material and wherein the content material is configured to compress in response to compression of the impact of the user and to expand the one or more baffles after termination of said compression.
