Apparatus for selecting mattress
First Claim
1. An apparatus for selecting a mattress which will be suitable for the anatomy of a user, comprising:
- a measuring mattress having a predetermined hardness, on which the user lies;
detecting means for detecting a load on each of a plurality of points of the measuring mattress when the user lies on the measuring mattress;
said detecting means including means for generating a detection signal indicating the load at each of the plurality of points, the load at each of the plurality of points deforming the measuring mattress by an amount determined by the actual load at each respective point;
control means for receiving the detection signal generated by said detecting means and for calculating a first average value that represents a plurality of deformations in the measuring mattress at a head portion and a leg portion of the user, said control means further calculating a second average value that represents a plurality of deformations in the measuring mattress at a plurality of other portions of the user excluding the head portion and the leg portion of the user; and
display means for displaying the first average value and the second average value calculated by said control means as a first straight line and a second straight line, respectively, said display means further displaying a mark which designates a hardness of a mattress suitable for the user, said hardness being determined on the basis of a comparison in the amounts of deformation represented by the first and second straight lines.

Abstract
Disclosed is an apparatus for selecting a mattress. The amounts of elastic deformation in a plurality of points of a measuring mattress having a predetermined hardness are electrically detected by pressure sensors. Based on the electric signals generated from the pressure sensors, a first average value in the amounts of deformation in the head portion and the leg portion of the user and a second average value in the amounts of deformation in the other portions of the user are calculated in a control device. First and second straight lines denoting these first and second average values, respectively, are displayed on a display device together with a mark designating the hardness of a mattress adapted to the user. The optimum hardness of the mattress is determined on the basis of the difference in the amount of deformation between the first and second straight lines, so as to enable the user to select a mattress of a hardness adapted to the user.

9. An apparatus for selecting a mattress which will be suitable for the anatomy of a user, comprising:
-
a measuring mattress having a predetermined hardness, on which the user lies; detecting means for detecting a load on each of a plurality of points of the measuring mattress when the user lies on the measuring mattress; said detecting means generating a detection signal indicating the load at each of the plurality of points; control means for receiving the detection signal generated by said detecting means and for calculating a first curve representing an actual load distribution on the measuring mattress when the user lies on the mattress, said control means further including means for storing a second curve representing a predetermined ideal load distribution on the measuring mattress and means for comparing the first and second curves; and display means for displaying said first and second curves and for indicating a hardness of a mattress adapted to the specific anatomy of the user based upon the comparison of said first and second curves.
