AI Technical Summary
Existing pads for orthoses or bandages with integrated wire ropes apply force linearly to the patella, leading to deformation and inadequate cushioning, and the force application point is too horizontal, causing instability and potential dislocation during knee movements.
A pad with a curved rein element, featuring a rotating section and offset design, applies force in a scissor-like manner, allowing for precise repositioning and minimizing rotational movement, thereby enhancing positional stability and cushioning.
The curved rein element design improves force application on the patella, providing better stability and preventing outward drift during knee flexion and movement, ensuring the patella is securely enclosed and aligned.

Description
[0001] DESCRIPTION
[0002] Pelotte with associated curved rein element
[0003] The present invention relates to a pad for an orthosis or bandage, in particular with an annular to semi-annular base, in particular for encompassing the patella, wherein a rein element is assigned to the pad, characterized in that the rein element is curved, and to an orthosis or bandage comprising a pad according to the invention.
[0004] The present invention therefore relates to a combination of a curved rein element and an associated pad for an orthosis or bandage, in particular with an annular to semi-annular base, in particular for encircling the patella.
[0005] Pads, especially pads for the kneecap, also called patella, with an integrated wire rope are known, for example, from EP 0 396 702 B1. In DE 90 17 540.9 U1, DE 295 19 979 U1, DE 295 19 978 U1, and DE 20 2004 001 936 U1, the ends of the pads are directly connected to reins.
[0006] The disadvantage of these pads is the linear application of force from the reins to the pad. This leads to deformation of the pad, which in turn moves in a linear motion to the desired position. Another problem with these reins is the lack of cushioning and absorption of tensions that occur in the reins and pad during everyday movements. The force applied to pads with state-of-the-art reins is too strongly horizontal, with the force applied approximately in the middle of the kneecap.
[0007] The present invention is based on the technical problem of providing an improved pad, in particular a pad with modified and improved force introduction, in particular force introduction onto the patella.
[0008] The present invention solves the underlying technical problem by a pad according to claim 1.
[0009] The present invention solves the technical problem underlying it in particular by means of a pad for an orthosis or bandage with an annular to semi-annular base for gripping the patella, wherein the pad is assigned a rein element, wherein the rein element is curved.
[0010] The present invention therefore relates to a combination of a curved rein element and an associated pad for an orthosis or bandage, in particular with an annular to semi-annular base, in particular for encircling the patella.
[0011] In a preferred embodiment, the curved rein element has a rotating section.
[0012] The curved rein element, especially the one with a pivoting section, surprisingly allows for a beneficial change in the force application point of the pad. Among other things, such a modified force application point is advantageous because, in certain cases, the loosely fitting kneecap tends not only to slide toward the outer edge of the knee joint but also to rotate.
[0013] The curved rein element still has the basic task of ensuring a certain degree of positional stability of the kneecap during knee flexion and related knee movements (preventing dislocation). The particular difficulty here lies in the fact that a force applied to the rein element, which is preferably inserted into the pad in certain areas, for example, by foaming, should not lead to a linear stretching of this pad area, but rather to a minimal rotational movement of the part of the pad equipped with the rein element. The area of the pad equipped with the rein element can, in a sense, prevent the kneecap from drifting outward and counteract this movement depending on the tensile force acting on the rein element, so that the kneecap is, in a sense, more tightly enclosed in certain areas.This is not done by stretching the pad area provided with the rein element, but by “twisting” or tilting this pad area towards the kneecap.
[0014] The inventive design of the rein element results in the force being applied from the bending point in a more scissor-like manner, rather than in a semicircular manner as in the prior art. The force application vector thus realized allows the pad to be repositioned more precisely. The design of the pivot section also directly affects the pivot point of the pad. It is assumed, without being bound by theory, that the patella naturally performs a rotational and tilting movement. This dual movement can be ideally replicated by the inventive pad with its curved rein element.
[0015] The invention also relates to a pad, in particular a pad as described above, wherein the curved rein element has an offset section, in particular as a rotary section, wherein in particular the rein element has a first curved section on the first side of the offset section and a second curved section on the second side of the offset section, wherein in particular the curvature of the first curved section runs on a different curved path, in particular a circular path, than the curvature of the second curved section.
[0016] According to the invention, the rein element associated with the pad preferably has an offset section which lies, for example, between a first curved section and a second curved section.
[0017] The advantageous movement of the rein element can be achieved in particular by guiding the curved rein element along two paths by means of a pivoting section, for example, an offset section. The offset section, for example, in the form of a hook connecting both curved sections, becomes the pivot point, as it interrupts the flow of tensile force in the offset area.
[0018] Advantageously, the offset section can also act as an additional anchor.
[0019] In a preferred embodiment, the rein element is a one-piece, curved rein whose radius of curvature is redirected in a “Z-shape”.
[0020] Preferably, the first curved section has the same radius as the second curved section or the first curved section has a different radius than the second curved section.
[0021] It is therefore preferred that the “circular path” of the rein element, which is formed by the first curved section and the second curved section, is shown with an offset.
[0022] The offset section—or web—between the two curved sections can, for example, have a length of at least about 1 / 3 of the width of the rein element to at most about 2x the width of the rein element. Preferably, the offset section has a length of at least about 1 / 3 of the width of the rein element.
[0023] The offset section can preferably extend from the first curved section of the rein element in an angular range of at least 30 degrees and can preferably extend from the first curved section of the rein element up to a maximum of 178 degrees.
[0024] In an alternative embodiment, the rein element, particularly as a pivoting section, has a section with increased flexibility, in particular a tapered section, a section with incisions, a section with zigzag-shaped recesses, or a meandering section. The section can also be designed as a film hinge.
[0025] The rein element is preferably one-piece. The rein element is preferably formed from a single material. The rein element is preferably substantially inelastic. The rein element is preferably formed from a harder material than the material of the base.
[0026] However, variants of the rein element are also conceivable in which the rein material combines elastic with inelastic sections or in which the rein element is made entirely elastic.
[0027] The rein element preferably has at least two, in particular three end sections.
[0028] Preferably, one end section of the at least two, in particular three end sections is formed by an anchor element which is positioned on one of the two curved sections or the offset section.
[0029] Preferably, in the area of the offset section, an additional bar, preferably approximately 0.5 to approximately 2 cm long, is provided from the rein element, which can advantageously function as an additional anchor in the pad. This additional anchor reinforces the special positional stability of the offset section.
[0030] The rein element is assigned to the pad, thus acting on the pad assigned to it. The rein element can be firmly connected to the pad or be located on or near the pad. According to the invention, an assigned positioning of the rein element is achieved if the rein element can act on the pad. The invention thus relates to a combination of pad, in particular the pad base, and the assigned rein element.
[0031] In a preferred embodiment, the rein element is firmly connected to the pad. Preferably, the rein element is cast into the material of the pad base or is positively connected to the material of the base.
[0032] Alternatively, the rein element can be positioned on, on, or next to the pad. The rein element can be firmly attached to the pad, for example, glued, or can be positioned directly on or directly against the pad. It can also be positioned in a guide, such as a groove in the pad, or it can be positioned on or above intervening elements, such as linings.
[0033] The rein element preferably has at least two, in particular three, end sections that protrude from the base of the pad. These can advantageously be connected to the base body, for example, the base fabric, an orthosis, or a bandage.
[0034] Suitable shapes and materials for the base of the pad are known to those skilled in the art. The pad preferably has a ring-shaped to semi-ring-shaped base. The base is preferably ring-shaped or nearly ring-shaped.
[0035] Preferably, the ring-shaped to semi-ring-shaped base serves to encompass the patella and has a corresponding dimension known to the person skilled in the art.
[0036] In a preferred embodiment, projections pointing distally to the joint are formed at the base of the pad, which, when the pad is in place, are located in the area of the infrapatellar fat bodies and can exert pressure on them.
[0037] In a preferred embodiment, the pad according to the invention is for a knee joint orthosis or knee joint support, an elbow orthosis or elbow support, a hand orthosis or hand support, a back orthosis or back support, or a hip orthosis or hip support. In a particularly preferred embodiment, the pad according to the invention is for a knee joint orthosis or knee joint support.
[0038] The present invention also relates to an orthosis or bandage comprising the reins element according to the invention, an associated pad, and a base element. The base element is preferably formed from or comprises a knitted or warp-knitted fabric. Suitable base elements are known to those skilled in the art.
[0039] Preferably, at least one end section of the rein element can be reversibly fastened to the base element.
[0040] Preferably, at least two end sections of the rein element are attached to the base element. Preferably, all end sections of the rein element are attached to the base element.

[0064] Figure 1 shows a pad (100) according to the invention for a knee brace or knee orthosis, comprising an annular base (10) for gripping the patella, wherein the pad (100) is associated with a curved rein element (22). The rein element (22) is formed in one piece and made of a single material that is inelastic and harder than the material of the base (10).
[0065] The shape of the rein element (22) is shown in Figures 2 and 3b. It is a rein element (22) with three end sections (26, 27, 28) that protrude from the base (10) of the pad (100), while the main portion of the rein element (22) is embedded in the base (10).
[0066] The front side of the pad (100) can be seen, i.e. the side facing the patient's knee and on which projections (11, 12) pointing distal to the joint are formed. When the pad (100) is in place, these projections are located in the area of the infrapatellar fat pads and can exert pressure on them. Figure 2 shows the back side of the pad (100) from Figure 1, i.e. the side facing away from the patient's knee and can rest on a base body of a bandage or orthosis. The base (10) of the pad (100) and the rein element (22) embedded in the base can be seen again, the course of which is indicated in the pad (100). The rein element (22) has, after the first end section (26) located outside the base (10), a first curved section (24) and a second curved section (25) which ends at the second end section (27) also located outside the base (10).Between the first curved section (24) and the second curved section (25) lies an offset section (23) acting as a rotary section (23). Attached to this offset section is a third end section (28) acting as an anchor, which also lies outside the base (10).
[0067] The force input vector realized by the rein element (22) according to the invention allows the pad to be repositioned more precisely. The design of the offset section (23) also directly affects the pivot point of the pad (100).
[0068] Figure 3 shows two embodiments of a rein element (21, 22) according to the invention. Figure 3a shows a rein element (21) with two end sections (26, 27), and Figure 3b shows a rein element (22) with three end sections (26, 27, 28), as embedded in the pad from Figures 1 and 2. Both rein elements (21, 22) have, after the first end section (26), a first curved section (24) and a second curved section (25), which ends at the second end section (27). Between the first curved section (24) and the second curved section (25) there is an offset section (23) acting as a rotary section. The curvature of the first curved section (24) has a first radius (rl) and the curvature of the second curved section (25) has a second radius (r2). The two radii (rl, r2) can be the same or different.For example, the first radius (rl) may be about 43 mm and the second radius (r2) about 85 mm, or the first radius (rl) may be about 50 mm and the second radius (r2) about 117 mm, or the first radius (rl) may be about 53 mm and the second radius (r2) about 84 mm.
[0069] The curvature of the first curved section (24) runs through the offset section (23) on a different curved path, in particular a circular path, than the curvature of the second curved section (25). In the rein element (22) of Figure 3b, the third end section (28) is positioned at the offset section (23), which can function as an additional anchor, i.e., can be connected to the base element of an orthosis or bandage, i.e., anchored.
[0070] The rein element does not necessarily have to run inside the pad, but can alternatively be positioned on, above, or next to the pad. The rein element can be firmly attached to the pad, for example, glued, or can be positioned directly on or directly against the pad. It can also run in a guide, such as a groove in the pad, or it can be positioned on or above intervening elements, such as linings.
[0071] Figure 4 shows the inside of a knee bandage (200) with a base element (300) made of a knitted fabric (301) and the pad (100) from Figures 1 and 2. The end sections (26, 27, 28) of the
[0072] Rein elements of the pad (100) can be permanently or reversibly connected to the knitted fabric (301) of the bandage base element (300).
