Embodiment Construction

[0049] figure 1 Two layers 2 of gasket material 4 are schematically shown. Each layer 2 has a plurality of fibers 6 which are arranged parallel to one another in the corresponding layer 2 . Between the individual layers 2, however, the fibers 6 are offset by 90 degrees relative to each other. In this case, the entirety of the fibers 6 in the upper layer 2 forms the first fiber layer 8 , while the entirety of the fibers 6 in the lower layer 2 forms the second fiber layer 10 . This arrangement of the fibers 6 in the first fiber layer 8 and the second fiber layer 10 in the abutted state of the pad with the two layers 2 results in an elastic deformation of the pad in one direction causing Elastic deformation in a second direction extending from the direction.

[0050] figure 2 A first fiber layer 8 and a second fiber layer 10 in a pad 16 according to an embodiment of the invention are shown. It is immaterial here whether the first fiber layer 8 and the second fiber layer 10 ...

Abstract

The invention relates to a liner (16) for a prosthesis, which liner (16) has a proximal opening, for receiving an amputation stump, and a distal end lying opposite the proximal opening, and it is produced from a liner material (4), wherein a longitudinal direction of the liner (16) extends from the proximal opening to the distal end, and a circumferential direction runs perpendicular to the longitudinal direction, wherein the liner (16) has a plurality of fibres (6), which are made from an inelastic material and are arranged in such a way that a lengthening of the liner (16) in the longitudinal direction results in a shortening of the liner (16) in the circumferential direction, and vice versa, wherein the liner (16) has non-slip means (26) which, when the liner (16) is fitted in place, prevent the liner (16) from slipping on the amputation stump.

Description

technical field [0001] The invention relates to a liner for a prosthesis, which has a mesial opening for receiving an amputation stump and a distal end and is made of a liner material, wherein the longitudinal direction of the liner extends from the proximal The central opening extends toward the distal end and the circumferential direction extends perpendicular to the longitudinal direction. The invention also relates to a prosthesis with such a pad and a prosthesis cartridge for such a prosthesis. Background technique [0002] Generic pads and prostheses equipped with such pads are already known in the prior art. The prosthesis has a prosthesis sleeve, which is conventionally produced from a hard material, for example from fiber-reinforced plastic. This material is easy to process, is strong and nevertheless has a low dead weight and is therefore very suitable as a component of a prosthesis. In order to avoid contact between the skin of the patient's amputation stump an...
