Abstract: A wheelchair sit-system with a three dimensional anatomical shape, which can accomplish an equal as well as an unequal pressure/load distribution, stabilize the pelvic base and trunk, compensate sit pathology, and be individually adapted on the basis of treatment of specific sit complaints/impairments. The wheelchair sit system (i.e., a sit cushion and a backrest) is developed methodically via inventory of the three dimensional pelvis/trunk measures; design a three dimensional drawing of basic sit cushions and backrest models in three sizes (S, M and L); specification of the sit pathology of the pelvis and trunk; and modification of the designed three dimensional basic sit cushion and backrest models on the basis of sit pathology. A product development trajectory results in nine sit cushion models in three sizes (S, M and L); six backrest models in three sizes (S, M and L); one generic sit cushion, with inserts, in three sizes (S, M and L); and one generic backrest, with inserts, in three sizes (S, M and L).

Abstract: The present invention is directed to a gelastic cushion. The gelastic cushion is made from a conventional gelastic composition. The gelastic cushion has a structure having a first wall that defines an opening area and buckles when a force is applied to the first wall. When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient (a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable.
