An adjustable chair having a back rest and a contour adjusting mechanism for adjusting the contour of the occupant engaging surface of the back rest. The contour adjustment mechanism comprises a series of longitudinally spaced adjustment linkages which also form part of the back rest. The contour adjustment includes adjustments for at least spinal curvature of an individual. For this purpose a gauge may be provided for pre-calculating the individual's back curvature, and this pre-calculation used in conjunction with the adjustment mechanisms to effect the desired adjustment of the occupant engaging surface.

An electronic system for adjusting a load bearing surface such as a chair or bed to provide a desired level of comfort comprises an array of pressure sensors located within the load bearing surface. The pressure sensors generate data indicating the actual distribution of pressure exerted by a user on the load bearing surface. An electronic processor processes the data generated by the array of pressure sensors. The processor compares the fraction of total load exerted on each of a plurality of regions of the load bearing surface with a desired range for each region. If the fraction of total load for any region is not within the desired range, a servo-mechanism is activated to change the shape of the load bearing surface so that the fraction of total load on each region is within the desired range, so as to provide a desired level of comfort to the user.

A mail bag is fabricated from canvas sewn together to form a bag body with a closed bottom and open top adapted to be closed by a draw string. Three sets of handles, each also formed of pieces of canvas, are sewn to the outer surface of the bag. A first set of four handles are sewn to the bag spaced around the bag in a line proximate the top of the bag; while a second set of four handles are sewn to the bag spaced around the bag in a line proximate the bottom of the bag and so as to be parallel to and aligned with the first set of handles. A third set of four handles are sewn to the bag spaced around the bag aligned with the handles of the first and second sets but so that the handles of the third set midway between handles of the first and second sets and so that the disposition of the hanldes of said third set is either perpendicular to the disposition of the handles of said first and second sets; or parallel thereto.

A device for supporting a human being comprises a superstructure defining a support surface in contact with a body part of a person and measurement componentry on the superstructure for periodically measuring a predetermined biomechanical parameter of the person's body part to determine a load distribution on the body part. The measurement componentry includes a fluid filled reservoir at the support surface and a pressure detector in operative engagement with fluid in the reservoir for monitoring changes in the pressure of the fluid, due, for example, to varying loads caused by physical activity. Circuitry is operatively coupled to the pressure detector for monitoring and characterizing changes in pressure of the fluid over time. Form control componentry is disposed on the superstructure and is operatively connected to the measurement componentry for automatically subjecting the support surface, in response to the determined load distribution, to forces tending to modify a contour of the support surface. The form control circuitry may include a pressurization source for modifying a base pressure of the reservoir fluid.

A seat housing a multiplicity of adjustable horizontal planes connected to a processor in turn connected to an input device responding to a prerecorded spinal profile information of an individual's spinal configuration submitted to the input device. A seat pan, inclinable and pivotally mounted, on rails that permit horizontal movement relative to the back rest is also supported by a viscoelastic layer. Horizontally adjustable headrest is mechanically linked to vertically adjustable arm supports to allow vertical movement of the assembly, matching that of the vertical displacement of the seat pan when the seat is in use.

A scissors which may be utilized by persons having weakened hand muscles is disclosed. The scissors comprises first and second blade elements. Each of the blade elements includes a front portion having a sharp cutting edge, a middle portion and a rear portion. The blade elements are pivotally mounted at the rear portions thereof and biased by a spring member towards the open position of the scissors. First and second handles are attached to the middle portions of the first and second blade elements, respectively. The handles increase the effective widths of the middle portions of the blade elements thereby increasing the mechanical advantage of the scissors. This permits a user of the scissors to close the scissors with a smaller force.

A method and apparatus are described for evaluating a load bearing surface such as a seat. Preferred apparatus for the practice of the invention comprises a plurality of sensors which are distributed across a load bearing surface such as a seat pan, apparatus for measuring the pressures exerted on the sensors when a weight is placed on the load bearing surface, and signal processing apparatus for evaluating the pressures that are measured. Advantageously, the signal processing apparatus can be utilized to store data which represents a comfort level for the load bearing surface and to evaluate the measured pressures in light of that data. For example, the data stored can be pressure measurements for a series of seats correlated with subjective appraisals of seat comfort and the evaluation can be performed by statistical analysis and comparison of the pressure measurements for a seat under test with the stored pressure measurements. Alternatively, the data stored can be a mathematical formula which relates pressure as measured at different areas of the seat pan to an index of comfort; and the evaluation can be performed simply by inserting the measured pressures into the formula and calculating the resulting index.
