초록 ▼

A cushion that includes a cushioning element. The cushioning element has a number of substantially parallel elongate columns formed in a gelatinous cushioning media. The columns are configured so that when a force is applied to the cushioning element in a direction that is generally parallel to the longitudinal axes of the columns, the cushioning element will yield by a combination of compressability of the cushioning media and bucklability of the walls of the columns. In particular, the walls of columns which are located beneath a protruberance on an object being cushioned tend to buckle, permitting the cushioning element to conform to the shape of the cushioned object while evenly distributing a supporting force across the contact area of the cushioned object and avoiding pressure peaks. The preferred cushioning media is a gelatinous elastomer or gelatinous viscoelastomer. Various configurations of cushioning elements, including sidewall supports, are disclosed.

대표청구항 ▼

[ I claim:] [1.] A yieldable cushioning element that includes a flexible, resilient, gel cushioning media having shape memory and being substantially solid and non-flowable at temperatures below 130 degrees Fahrenheit, the cushioning element comprising:a quantity of gel cushioning media formed to have a top, a bottom, and an outer periphery, the cushioning media being compressible so that it will deform under the compressive force of a cushioned object, anda plurality of hollow columns situated in said cushioning media, each of said columns having a longitudinal axis along its length, each of said columns having a column wall which defines a column interior, and each of said columns having a column top and a column bottom;wherein the cushioning element is adapted to have a cushioned object placed in contact with said cushioning element top; wherein the column top and the column bottom of one of said columns are located at two different points on said longitudinal axis of said column;wherein said column's longitudinal axis is located generally parallel to the direction of a compressive force exerted on the cushioning element by a cushioned object in contact with said column top;wherein at least one of said column walls is capable of buckling beneath a protuberance that is located on a cushioned object; andwherein the cushioning element is yieldable as a result of compressibility of said cushioning media and bucklability of said column.
