Abstract
A cushion member includes a resilient material body having multiple different diameters defining a body bell-shape. The body includes a solid first portion having a first diameter. An aperture extends through the first portion transverse to a body longitudinal axis. A hollow second portion defines a hollow chamber in communication with the aperture. The second portion has a second diameter larger than the first portion first diameter. A third portion has a third diameter smaller than the second diameter. An end flange is connected to the third portion. The differing first, second, and third diameters induce the body to elastically compress when a force is applied to the end flange and to return to an uncompressed state after force dissipation. A flow rate of air forced out of the hollow chamber during second and third portion compression and out the aperture is restricted by an aperture diameter.
