Abstract
Abstract A tubular base body (1), made from an elastic textile material, has, in its central zone (II), a greater elastic stretchability than in the two adjacent rim zones (I and III). A stabilization zone (4) inclined by 15° to 45° relative to the main axis (A) is fitted on each flank, so that, in a front view, the two stabilization zones coverge in the shape of a V below the knee. The upper section (I) of the base body preferably has a considerably greater length (H) than the lower section (h), and this results in excellent resistance to sliding, in interaction with the holding strips (2,3) provided in the rim zone and with the different stretchability of the three zones mentioned. The knee bandage which can be used both for an injured knee and for a healthy knee is deliberately designed to fulfil the three functions of stabilization, guiding and warming of the knee region.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
221 words
Knee bandage having a tubular base body which consists at least partially of an elastic textile material and comprises a central region which is to be laid against a knee joint, as well as two edge sections which adjoin this central region on both sides and the stretch properties of which differ from those of the central region, characterised in that, when the central region (II) and edge sections (I, III) are equally loaded, the central region (II) has an elastic stretch in the longitudinal and transverse directions which is at least 100% greater than that of the edge sections (I, III), that two zones (4) for stabilising the joint flanks are provided on the base body (1), which zones are each inclined relative to the longitudinal centre line (A) of the base body by an angle of 15°-45° and are arranged, on the one hand, to converge towards one another up to a region on the base body located below the position to be envisaged for the knee joint and, on the other hand, to extend beyond the knee region, and that at least that edge section (I) which adjoins the central region above the knee region is provided on the inside of its upper edge part with a holding strip (2) made of material which is resistant to sliding.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
37 words
Knee bandage according to claim 1, characterised in that a holding strip (3) preferably consisting of a silicone rubber is arranged on the inside of the upper edge part and on that of the lower edge part.
Claim 4
Dependent Claim
34 words
Knee bandage according to claim 1, characterised in that the region of the hollow of the knee has a slot-shaped recess (6) which extends at most over the height of the central region (II).
Claim 5
Dependent Claim
22 words
Knee bandage according to claim 3, characterised in that the slot-shaped recess extends over a height of between 15 and 50 mm.
Claim 6
Dependent Claim
39 words
Knee bandage according to one of claim 4, characterised in that the said stabilising zones (4) extend in a straight line and, in a front view of the knee bandage, at least approximately in the form of a V.
Claim 7
Dependent Claim
26 words
Knee bandage according to one of claim 5, characterised in that the stabilising zones (4) are formed by bands which are sewn on or glued on.
Claim 8
Dependent Claim
19 words
Knee bandage according to claim 6, characterised in that the bands are reinforced by an impregnation with silicone rubber.
Claim 9
Dependent Claim
38 words
Knee bandage according to one of claim 1, characterised in that the stabilising zones (4) are formed by a multiplicity of stabilising filaments which are interwoven, in the particular stabilising region, with the fabric of the knee bandage.
Claim 10
Dependent Claim
29 words
Knee bandage according to one of claim 1, characterised in that its material in the region of the stabilising zones (4) is impregnated with a natural or synthetic rubber.
Claim 11
Dependent Claim

Dependent Claim
33 words
Knee bandage according to one of claim 10, characterised in that its upper section (I) lying against the thigh is at least 50% longer than the lower section (III) facing the lower leg.
Claim 13
Dependent Claim
