Abstract

An apparatus is provided which includes a support device secured to a structure. The apparatus comprises first and second chambers containing first and second fluids wherein the resiliency of one of the chambers is lower than the resiliency of the other chamber. The chamber having the lower resiliency is positioned so as to be closer to the body of a user than the other chamber. The support device in the apparatus is secured to a structure which can include but is not limited to, back supports, automobile seats, helmets, casts, cervical collars, automobile air bags, and wrist supports for keyboards and mouse pads. The fluid media used in the support device includes air, liquids, and gels. An additional chamber may be employed between the first and second chambers in the support device to provide stability to the support device. A method for using the support device to support various user body portions is also disclosed.

Claims

1. An apparatus comprising a support device secured to a structure, said support device comprising:

a first chamber containing a first fluid; and

,

a second chamber, disposed generally adjacent to said first chamber, containing a second fluid, wherein the fluid in one of said chambers provides a first resiliency, the fluid in the other of said chambers provides a second resiliency different from said first resiliency, and said support device secured to said structure so that in normal use said chamber having the lower resiliency is positioned closer to the body of a user than the other of said chambers.

2. The apparatus of claim 1, wherein at least one of said fluids is a gel.

3. The apparatus of claim 2, wherein said gel is a low density, deformable gel composition.

4. The apparatus of claim 1, wherein said fluid is selected from the group consisting of pseudo-liquid, thermoplastic liquid, water, oil, glycerine, liquid-plastic microspheres, emulsions, plasticizers, and colloidal suspensions.

5. The apparatus of claim 1, wherein said fluid in said higher resiliency chamber is air.

6. The apparatus of claim 5, wherein said air is under a pressure of no more than about 6 pounds per square inch.

7. The apparatus of claim 1, wherein one of said chambers is contained within the other of said chambers.

8. The apparatus of claim 7, wherein said contained chamber contains air and the other of said chambers contains a liquid.

9. The apparatus of claim 7, wherein said contained chamber contains a fluid and the other of said chambers contains a gel.

10. The apparatus of claim 9, wherein said fluid is a gel providing a resiliency different than the resiliency provided by said contained gel.

11. The apparatus of claim 1, wherein each of said chambers has substantially the same volume.

12. The apparatus of claim 1, wherein one of said chambers has a greater volume than the other of said chambers.

13. The apparatus of claim 1, wherein said chambers are substantially continuous, and said support device has a first surface secured to said structure and a second surface in contact with a body part of the user being supported.

14. The apparatus of claim 1, wherein said structure is selected from the group consisting of a back support, an automobile seat, a helmet, a cast, a cervical collar, an automobile air bag, and a wrist support.

15. The apparatus of claim 1, further comprising an additional chamber positioned between said first and second chambers.

16. The apparatus of claim 15, further comprising a layer of fully reticulated foam disposed in said additional chamber.

17. The apparatus of claim 16, further comprising a valve means in communication with said additional chamber for pressurizing and depressurizing said additional chamber with a gas or fluid, thereby expanding and contracting said reticulated foam in response to actuation of said valve means.

18. A method of using a support device with a structure to support a body part comprising:

providing a support device comprising a first chamber containing a first fluid, and a second chamber, disposed generally adjacent to said first chamber, containing a second fluid, wherein the fluid in one of said chambers provides a first resiliency and the fluid in the other of said chambers provides a second resiliency different from said first resiliency;

securing said support device to said structure; and

,

positioning a body part in contact with said support device so that said chamber having the lower resiliency is closer to the body of a user than the other of said chambers.

19. The method of claim 18, including employing a helmet having an interior as said structure, securing said support device to said interior, and positioning the head of a user in contact with said support device.

20. The method of claim 18, including employing an automobile seat as said structure.

21. The method of claim 18, including providing said chambers as substantially continuous, and employing a support device having a structure engaging surface and a back support surface to support at least a portion of the back of a user.

22. The method of claim 18, including employing a cast as said structure.

23. The method of claim 18, further including employing a valve means positioned on said chamber having air as said fluid to make said air chamber inflatable or deflatable.
