- cushion member 458 of forehead pad 450 includes a housing portion 460 (shown in hidden line in FIG. 9 and generally in FIG. 10) within cushion member 458.
- Cushion member 458, and, thus, housing portion 460 is formed from a slightly curved first wall 468 structured to contact the patient, and a second wall 470, generally curved a greater amount than first wall 468.
- Second wall 470 is coupled to main body portion 452 thus coupling cushion member 458 and main body portion 452 together.
- main body portion 452 and cushion member 458 are formed as a unitary member, however it is to be appreciated that main body portion 452 and cushion member 458 could be formed separately without varying from the scope of the present invention.
- an opening 462 providing access to housing portion 460 is formed in main body portion 452. Housing portion 460 allows for a support element, such as one of those depicted in FIGS. 11-13, to be inserted into cushion member 458.
- FIG. 11 and 12 show an exemplary support element 480 according to an embodiment of the invention in which support element 480 is custom formed from a "closed" cell skinned foam material, such as a silicone-foam material, formed to cooperatively fit within housing portion 460 of cushion member 458.
- the flexible nature of cushion member 458 and support element 480 allow for the insertion of support element 480 into cushion member 458 via opening 462. Once installed, cushion member 458 substantially surrounds support element 480.
- a silicone-foam material having a density (pcf) of about 14.5, a softness (Shore ⁇ ') of about 20-25, and an average cell size (mm in diameter) of about 0.5 (fairly uniform ranging from about 0.2 to 0.8) in open cell structure, has been employed.
- a polyurethane foam either Ester or Ether having a density (pcf) of about 8.5, a softness (Shore ⁇ ') of about 20-25, and an average cell size (mm in diameter) of about 0.5 (fairly uniform ranging from about 0.2 to 0.8) in open cell structure, has been employed.
- support element 480 may also be formed from an "open" cell soft foam material such as, for example without limitation, any non structural foam with compression and expansion capability, typical materials are Polystyrene and Polyurethane.
- Such "open” cell foam material may be die cut, such as shown by support element 480' of FIG. 13.
- Such "open” cell material may be suitably formed to have a desired shape, such as, for example without limitation, the shape of support element 480 of FIGS. 1 1 and 12. In either case, the rather soft nature of support element 480' will generally result in support element 480' contouring to the shape of housing portion 460.
- support element 480 may also be formed from any suitable resilient cushioning material, and may include, for example and without limitation, more than one element and/or different sizes or variations of elements formed from alternative materials, such as gel, foam, silicone, or viscoelastic foam or memory foam. Additionally, the selection of the particular material employed as support element 480 or, at minimum, particular attributes of the material, may be left up to the end user (patient) to allow for custom tailoring of forehead pad 450 by the patient. In such instances, a number of different types of interchangeable support elements 480 would be supplied from which the patient could pick and choose as desired to customize the feel of forehead pad 450 as desired.
