Measuring apparatus for shearing force for seating

The present invention by providing a shear force sensor or the like seat portion, and measuring the shear force on the main portion which contacts with the seating when the seat portion, to provide a seat occupant when the shear force measuring device, increase the accuracy of the measurement it is an object. Seat occupant upon the shear force measuring instrument according to the present invention to achieve the above object is installed in the seat portion of a shear force sensor detecting a shear force generated when a seat occupant; A signal processor for filtering and amplifying signals from the shear force sensors, and converts the digital signal to an amplified analog signal; And a monitor unit for display and analysis of the converted signal from the signal processing unit; characterized in that the to be able to measure the shear force in any direction that occurs when a seat occupant, including.
