Abstract
Abstract An orthesis for the human knee, having two joints which are disposed at the sides of the knee and from which there project arms which embrace the knee-cap and meet in pairs above and below the knee-cap in a centrally disposed tongue in each case, by each of which tongues at least one thigh strap and one leg strap respectively are carried above and below the knee. Each tongue is connected to its associated strap by an interchangeable longitudinal rail, placed in position from the outside, via adjustment means which, substantially in the region of the torque, determine the strap axis in rotation to the joints, and in the region of the strap, determine its distance from the joints.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
An orthesis brace for the human knee comprising two rotatable joints defining a rotational axis and which are disposed at the medial and lateral sides of the knee, said joints having proximal and distal arms extending therefrom, said arms being configured to embrace the kneecap and including a centrally disposed tongue extending outwardly proximally and distally from said proximal and distal arms, respectively, along the front of the leg; each of said tongues carrying at least one thigh strap and one leg strap above and below the knee; and an adjustment means connecting said tongue to said at least one thigh and leg straps, respectively by an interchangeable longitudinal rail, said adjustment means providing for angular adjustment of the longitudinal rail and the respective strap in relation to the rotational axis of the joints, said longitudinal rail further including means for adjusting the distance of the strap from the joints.
Claim 2
Dependent Claim
150 words
An orthesis brace for the human knee comprising two rotatable joints defining a rotational axis and which are disposed at the medial and lateral sides of the knee, said joints having proximal and distal arms extending therefrom, said arms being configured to embrace the kneecap and including a centrally disposed tongue extending outwardly proximally and distally from said proximal and distal arms, respectively, along the front of the leg; each of said tongues carrying at least one thigh strap and one leg strap above and below the knee; and an adjustment means connecting said tongue to said at least one thigh and leg straps, respectively by an interchangeable longitudinal rail, said adjustment means providing for angular adjustment of the longitudinal rail and the respective strap in relation to the rotational axis of the joints, said longitudinal rail further including means for adjusting the distance of the strap from the joints.
Claim 3
Dependent Claim
53 words
An orthesis according to claim 1 further characterized in that the tongues end in extensions each overlapping an arm and which are connected to a respective arm by other adjustment means for determining the length of the overlap in the longitudinal direction of the arms to thereby provide for adjustment in size thereof.
Claim 4
Dependent Claim
36 words
An orthesis according to claims 1 or 2 further characterized in that the longitudinal rails are of different length and each is provided with a plurality of adjustment means for fitting a plurality of straps thereto.
Claim 5
Dependent Claim
27 words
An orthesis to claims 1 or 2 further characterized in that the straps adjacent to the joints are tapered to thereby follow the anatomy of a user.
Claim 6
Dependent Claim
43 words
An orthesis according to claims 1 or 2 further characterized in that the straps are provided at their ends with slots receiving bands therein, the slots being disposed in a direction such that the bands lie flat against the leg of a user.
Claim 7
Dependent Claim
37 words
An orthesis according to claim 5 characterized in that the bands are symmetrically constructed with a self-gripping fastener support at each end thereof for simultaneously tightening the bands at both sides of the leg of the user.
Claim 8
Dependent Claim
32 words
An orthesis according to claims 1 or 2 characterized in that the straps are provided with holding elements for attachment of pads of different thickness which may be attached to the straps.
Claim 9
Dependent Claim
36 words
An orthesis according to claims 1 or 15 characterized in that pivotal slot eyes are provided on both the joints for receiving bands extending in the region of the hollow of the knee of the user.
Claim 10
Dependent Claim
75 words
An orthesis according to claim 8 characterized in that the pivotal slot eyes are provided on each arm or on each extension for receiving bands extending around the hollow of the knee in such a manner that starting from the slot eyes on the arms or extensions, a crossing of the band results above and below the hollow of the knee in each case, with the band extending through the slot eyes on the joints.
Claim 11
Dependent Claim
31 words
An orthesis according to claims 1 or 15 characterized in that the joints are provided at their inside with a self-gripping fastener for attachment of pads or different thicknesses and shapes.
