The following statement is a full description of this invention, including the best method of performing it known to me/us:

CUSHION BACKGROUND OF THE INVENTION

[00011 1. Technical Field

[00021 The present disclosure relates to buttock supporting equipment and, more

particularly, to a cushion with multiple levels of softness.

[00031 A cushion is a soft thing which a user sits on comfortably as it supports the

user's buttocks sufficiently. However, the cushion does not give sufficient support to the

buttocks of users who lead a sedentary lifestyle or have paralyzed lower limbs, and in

consequence hipbones are under prolonged pressure to the detriment of blood circulations,

leading to bedsores. Therefore, it is imperative to provide a solution.

BRIEF SUMMARY OF THE INVENTION

[00041 It is an objective of the present disclosure to provide a cushion structured

to give multiple degrees of support.

[00051 In order to achieve the above and other objectives, the present disclosure

provides a cushion comprising a pad, an envelope, and a support pad set. The pad has a

sunken portion. The envelope is disposed on the pad. The envelope has a pocket-shaped

body. A plurality of coupling portions is disposed at edges of the body. The support pad

set includes an upper foam pad, a lower foam pad, and a soft gel pad. The support pad set

is disposed in the body of the envelope.

DETAILED DESCRIPTION OF THE INVENTION

[00121 Referring to FIG. 1 through FIG. 6, a cushion of the present disclosure

comprises a pad 10, an envelope 20, and a support pad set 30.

[00131 The pad 10 is integrally made of foam and has a top side 11, a bottom side

12, and a lateral side 13 disposed between the top side 11 and the bottom side 12 and

surrounding the pad 10. The pad 10 sinks in the direction pointing from the top side 11 to

the bottom side 12 to form a sunken portion 14. The sunken portion 14 has a bottom

portion 141 such that a height difference is formed between the bottom portion 141 of the

sunken portion 14 and the top side 11 of the pad 10. The upper edge of the sunken

portion 14 sinks and tapers in the direction pointing from the top side 11 of the pad 10 to

the bottom side 12 of the pad 10; hence, the upper edge of the sunken portion 14 is wider

than the bottom portion 141 of the sunken portion 14. A plurality of through holes 15 is

disposed on the bottom portion 141 of the sunken portion 14 and penetrates from the

bottom portion 141 of the sunken portion 14 to the bottom side 12 of the pad 10. In this

embodiment, the pad 10 is made of high-density (3.5Lb/ft -5Lb/ft 3) foam polyurethane.

The bottom portion 141 of the sunken portion 14 has four through holes 15. The pad 10 is

of such a shape that it is ergonomic for a sitting person and conducive to good posture and optimal pressure distribution.

[00141 The envelope 20 has a pocket-shaped body 21. The body 21 has an outer

lateral side 22 and an inner lateral side 23. A plurality of coupling portions 24 is disposed

at the edges of the body 21. In this embodiment, the body 21 is a rectangular cuboid, and

a coupling portion 24 is disposed at each of its four edges. The coupling portions 24 each

comprise a fabric 241 and a velcro strap 242. The fabric 241 is connected to the body 21,

whereas the velcro strap 242 is disposed on the fabric 241, but the present disclosure is

not limited thereto. In a variant embodiment, the coupling portions each include a fabric

and a button, include a fabric and a zipper, or include a velcro strap. A plurality of

coupling bands 25 is disposed on the inner lateral side 23 of the body 21. The coupling

bands 25 are each provided with a fastening portion and are paired. The fastening

portions are fastened to each other or to the bottom side 12 of the pad 10. The envelope

20 corresponds in shape to the pad 10 substantially and is disposed on the top side 11 of

the pad 10. The inner lateral side 23 of the envelope 20 faces the top side 11 of the pad 10.

The coupling portions 24 bend downward to therefore cover the lateral side 13 of the pad

10, then extend to therefore cover the bottom side 12 of the pad 10, and finally the velcro

straps 242 of the coupling portions are coupled to the bottom side 12 of the pad 10. The

coupling bands 25 penetrate the through holes 15 of the sunken portion 14 of the pad 10,

respectively, and then are paired before being coupled together or fastened to the bottom

side 12 of the pad 10 by the fastening portions.

[00151 The support pad set 30 comprises an upper foam pad 31, a lower foam pad

32, and a soft gel pad 33. The upper foam pad 31 and the lower foam pad 32 correspond

in shape to the pad 10 substantially. The lower foam pad 32 has a receiving hole 34. The

soft gel pad 33 is disposed in the receiving hole 34. The support pad set 30 is disposed in

the body 21 of the envelope 20. The upper foam pad 31 is made of gel infused

viscoelastic foam polyurethane (4Lb/ft¾~6Lb/ft). The upper foam pad 31 provides comfort and promotes blood circulation. The soft gel pad 33 is made of high-viscosity silica gel to not only relieve the pressure otherwise imposed on ischium and coccyx but also prevent shear force. The two advantages are conducive to prevention of bedsores.

The lower foam pad 32 is made of high-density, high-elasticity foam polyurethane (54Lb

IFD~58Lb IFD) and covers the edges of the soft gel pad 33 to exert an upward,

supportive force on the greater trochanter of femur from below and thus sink further into

the soft gel pad 33 so as to reduce the pressure otherwise imposed on ischial tuberosity

and coccyx. The IFD means Indentation Force Deflection. The soft gel pad 33 of the

support pad set 30 is a good pressure-relieving zone for eliminating the pressure

otherwise imposed on the coccyx and sacrum to provide comfort and prevent bedsores.

[00161 The cushion of the present disclosure is advantageous in that the envelope

can be coupled to or separated from the pad easily and quickly so as to be changed or

cleaned by users easily.

[00171 The pad operates in conjunction with the support pad set which has

multiple levels of softness. While a user is sitting on the pad, the pad gives different

degrees of support to different parts of the user's buttocks, for example, supporting the

ischium with the soft gel pad of the support pad set.

[00181 Depending on the material or softness of the support pad set disposed in

the envelope, the user can vary or adjust the cushion's degree of softness and supportive

strength as needed, thereby the user's need for customization. Furthermore, both the pad

and the support pad set can be independently changed to enable different combinations.
