Embodiment Construction

[0019] exist figure 1 A pressure control and feedback system 10 for an adjustable foam support device 12 is shown in . Various supports of this type are disclosed in US Patent Nos. 6,684,433, 6,745,420 and 6,922,863, the disclosures of which are incorporated herein by reference. In particular, adjustable support 12 comprises a sealed self-expanding foam core with incrementally adjustable levels of hardness and softness. Such supports can be used in a wide variety of products including (but not limited to) mattresses, toppers, mats, pads, seat covers, recliners, car seats, etc. . The specific application of the adjustable foam support device is not a limitation of the invention.

[0020] The density and stiffness of device 12 can be incrementally adjusted by removing a selected amount of air from the foam core through the sealing cover. In particular, the vacuum pump unit U is communicable and operatively interconnected with the foam core of the device 12 . In the form des...

Abstract

The invention provides a pressure control and feedback system used for adjustable foam support equipment. The system comprises a vacuum pump which is communicated with gas of a sealed foam core body, and air is pumped out from the core body, so that the hardness of the core body is reduced and the softness of the core body is increased. A valve is opened and closed alternatively, so as to allow the air to enter into the core body or prevent the air from leaving the core body. A controller operated remotely generates and sends out a selected control signal by a programmable CPU (central processing unit) so as to operate the pump and the valve. Each control signal represents a corresponding hardness level in multiple hardness levels of the core body. The control signal selectively starts and stops the operation of the pump and selectively opens and closes the valve, so as to provide air pressure and corresponding hardness of a selected level in the core body. A pressure sensor detects the pressure and hardness of the core body and generates a feedback signal representing the pressure and hardness. An indicator device responds the feedback signal, so as to indicate the sending hardness of the core body.

Description

technical field [0001] The present invention relates to a system for controlling and providing feedback on the pressure, firmness, contour and support of an adjustable foam support device. Background technique [0002] I have recently introduced adjustable foam mattresses and supports where a vacuum pump is used to adjust the level of vacuum pressure in the foam core in order to achieve a desired density and firmness / softness. Typically, the foam core becomes softer and more conformable when the air is removed, but allowing the core to partially or fully actively self-expand increases the stiffness of the strut. Precise custom grades of firmness, softness or conformity are not possible for the individual user as foam beds are currently sold with factory preset density and IFD values ​​which cannot be changed by the user. Individual users vary widely in size, shape and build. Thus, there would be an almost endless variety of possible proposed optimum levels of corresponding...
