Claims8
A method for adjusting the firmness or height or sag of a body support device, comprising:
- obtaining, at a time t1, a baseline pressure or compression/decompression or sag profile of the body support device when a body is being supported by the body support device;
- and
- adjusting, at a later time t2, the firmness or height or sag of at least a portion of the body support device based on the baseline pressure or compression/decompression or sag profile obtained at the time t1.
A body support device with adjustable firmness or height or sag, comprising:
- means for obtaining, at a time t1, a baseline pressure or compression/decompression or sag profile of the body support device when a body is being supported by the body support device;
- and
- means for adjusting, at a later time t2, the firmness or height or sag of at least a portion of the body support device based on the baseline pressure or compression/decompression or sag profile obtained at the time t1.
An adjusting device for adjusting the firmness or height or sag of a body support device, comprising:
- a motor,
- a pully that is driven by the motor,
- a reduction gear that adjusts the rotation of the pully by the motor, and
- a movable piece that is semi-stiff and is driven by the motor via a string, wherein the string is attached to the movable piece and is configured to be released from or wound on the pully in order to adjust the firmness or height or sag of the body support device.
An adjusting device for compressing or decompressing one or multiple layers of a body support device, comprising:
- a top part attached to the top of the one or multiple layers, the top part comprising multiple magnets and/or electromagnets, and
- a bottom part attached to the bottom of the one or multiple layers, the bottom part comprising multiple magnets and/or electromagnets, wherein one or more magnets and/or electromagnets from the top part overlap one or more magnets and/or electromagnets from the bottom part,
- wherein when the one or multiple layers is compressed by magnetic force, a larger number of the magnets or electromagnets from the top and bottom parts overlap each other, thereby producing a greater magnetic force to compress the one or multiple layers.
