  • Patent number: 11118986
    Abstract: The present invention relates to a shear force measuring device for measuring a shear force of a human body relative to a seat, such as a chair, wheelchair, aircraft seat, the device including: a frame for providing a mechanical, substantially slide-free connection to the seat, a force sensor arranged on the frame, shear force receiving means for receiving the shear force which are coupled to the sensor. The shear force receiving means are arranged and configured such that shear force exerted on the shear force receiving means is transferable to the sensor so that the shear force is detectable by the sensor.

  • Patent number: 6393642
    Abstract: A supporting device (1) such as, for instance, a cushion, comprising a space (3) formed by a flexible envelope (2) and filled with a plurality of elements (4). The elements (4) in the space (3) are movable relative to each other and each consist of a gas-filled, flexible and thin-walled covering of gastight design, so that the elements are deformable for distributing a load over the supporting device. The covering of a number of elements is manufactured from at least substantially nonelastic material. These elements are each filled with the gas for 50-98 percent of their maximum volume and have a volume of from 10 cm3 to 100 cm3.
