Gel cushion

摘要

A gel cushion, such as may be incorporated in a knee pad or other body-worn pad, that avoids undue accumulation of heat within the cushion, and that provides a stable and comfortable resting surface for at least a portion of a user's body. The cushion may further provide decreasing incremental compression in response to incrementally increasing loads, whereby users of different weights may be comfortably supported thereon.

主权项

1. A cushion for a user comprising:
a planar member having a first surface and a second surface; wherein the first surface comprises an array of resilient mounds comprising mounds and channels between the mounds wherein each mound of said array contains a resilient gel material and wherein said mound array is always directed towards a cushioned body part of the user of said cushion and is in contact with the user and wherein the user is cooled by fluid flow through the channels; wherein the second surface is substantially flat and wherein said second surface does not contact the user; and wherein the array of resilient mounds is adapted to partially deform in response to a force applied thereto by the user wherein said array of mounds is integrally molded with the planar member and each mound comprises a cylindrical base portion which compresses a relatively larger distance for a first incremental value of force applied, and compresses a relatively smaller distance for additional incremental increase of the value of force applied; whereby channels defined between mounds of said array are not eliminated even when a maximum force is applied to the mounds.
