Abstract: An anatomically shaped seat shell includes a first lateral profile and a second lateral profile with a longitudinal axis located between the first lateral profile and the second lateral profile, a median support located edgeways to the longitudinal axis of the scat shell and having an upper edge portion and a lower edge portion and seat bands located transverse to the median support and connected to the upper edge portion of the median support, the first lateral profile and the second lateral profile. A method of construction is also disclosed. By automatically adjusting the seat bands to the individual profile of the buttocks or posterior of a user, a high sitting stability and a high evenness of the distribution of sitting pressure are achieved. The distance of the seat bands from one another, in combination with an open-pore cellular material pad cut to the same thickness, provides a very good microclimate.

Abstract: A method of measuring a body region of a human body includes recording at least two images of the body region from different camera positions, from which the contour lines are ascertained, for example, as a contrast. Used for scaling the images is a reference object with a reference zone, to which the camera is set in a perpendicular or near perpendicular viewing direction by means fan angle-determining device. The reference zone can be defined, for example, by perpendicularly protruding fins. From the projected images of the contour line and the reference zone, an individual model of the outside surface of the body region is subsequently ascertained by means of the reference model. From this individual model a prosthesis or orthesis can be fabricated.

Abstract: A process for the production of moldings from a polymer alloy of multiphase morphology, in which the polymer alloy is prepared with the injection molding in one process step. For this, thermoplastically processable polymers which are incompatible or not very compatible with one another are introduced as granules, preferably having a particle size of greater than or equal to 3 mm, into the hopper of an injection molding machine and are subsequently plasticized, mixed thoroughly, and shaped in the injection molding machine; where at least one of the polymers employed is capable chemically, under the injection molding conditions, of association and/or copolymerization with at least one other of the participating polymers. The resulting polymer alloys are not inferior in their properties to corresponding conventionally produced alloys. The moldings are useful in orthopedics.

Abstract: The invention relates to a linear sliding connection (1; 14; 18; 21; 29; 33) between two structural parts (2, 3, 9, 10; 3, 38, 39, 40, 2, 3, 10, 25). Said structural parts can slide back and forth in relation to each other with a damping effect in at least one of the two directions of movement. The invention is characterised by a mechanical friction damping element with a wire basket (4) which acts as a friction or clamping element. Said wire basket (4) encompasses the first (2, 3; 3, 38) of the two moveable structural parts concentrically on a longitudinal section in such a way that it rests on the outer surface of said first structural part, with one axial end (first basket end 4a) fixed on the second structural part (9, 10; 39, 40; 25, 10) and the other axial end (second basket end 4b) positioned on said second structural part in such a way that it is axially slideable in a longitudinal direction.

Abstract: The invention relates to a wheelchair having side frames including tube sections having a tube-bend at the front bottom end of each in an area proximate to where a bearing housing is mounted. The bearing housing has an approximately vertical bearing bore for accommodating an upwardly directed axle pin of a steering fork for holding a caster. The bearing housing also has an adjustment device, which is integrated in the screw mounting, for adjusting the bearing housing with respect to the side frame in order to align the bearing bore perpendicular to the ground. The bearing housing is mounted to the tube-bend via a guide passage of a clamping shell, which is correspondingly curved and is open on one side. The clamping shell is fitted laterally to the tube-bend and, is displaceably guided and is fixable in the desired position by tightening at least one clamping screw.

Abstract: The invention relates to a brake joint for a prosthesis, in particular, to a brake-action knee joint for a leg prosthesis. There is an upper joint part, a lower joint part, and a joint shaft for pivotally connecting the upper and lower joint parts. The joint shaft is connected to the lower joint part in a rotatably fixed manner and is designed as a brake shaft. The joint shaft is surrounded by a brake arrangement, which bears upon the joint shaft it and is arranged in a cylindrical recess, which, together with the joint shaft, forms an annular chamber in a clamping part forming a central joint part. The upper joint part is mounted to the clamping part in an articulated manner via a pivot pin in such a way that the upper joint part, when loaded, impacts on the clamping part and thus the brake arrangement and thereby exerts a braking action on the joint shaft.
