    l/IETHOD OF ATTACHING AN ARTIFICIAL TENDON AND A PRODUCT Technical field The present invention concerns a method of attaching an artificial tendon, a resulting product and a device having the resulting product.
    Background art Artificial tendons are used both for flexing and extending joints of human bodies, especial-ly the joints of fingers. For example strengthening gloves are known, using differentoperating principles, using wires or cables, such as artificial tendons, in order to applypushing and/or pulling forces onto particular points on each finger to be strengthened. Forinstance, electric or pneumatic driving mechanisms may be employed in order to pull the artificial tendons.
    The artificial tendons are for example provided in sewn channels made of flexible materialsuch as textile material or encapsulated in Bowden cables, which are attached in support positions.
    Summary ofthe invention The present invention aims to provide a solution of attaching artificial tendons that is cost effective yet functional with a resulting product which is comfortable for the user.
    According to a first aspect a method of attaching an artificial tendon at a support devicehaving a supporting material wall is provided. The artificial tendon is provided for flexing or extending a joint of a body by means of pulling the artificial tendon along its lengthwise Application text 2015-04-29 C:UsersyvjoDesktop150429 Application text zig zag 150025SE.docx direction when it is applied at the joint of the body. The method comprises at least thesteps of - stitching across the artificial tendon with a low friction thread, and - forming a tunnel for the artificial tendon between the supporting material and the stitching, in which tunnel the artificial tendon may travel.
    By means of the stitching across the artificial tendon the thread will be at least on bothsides ofthe artificial tendon or even surrounding it and thus form a tunnel-like attachment to the supporting material wall.
    This is an effective method of attaching an artificial tendon compared to sewing channels.Also, a flat appearance is provided, which is not affecting the comfort for the user. Anoth-er advantage is that the artificial tendon will easily slide against the thread of low frictionmaterial. Even better results will be achieved if also the artificial tendon has a low friction surface.
    According to an embodiment of the method, it also comprises the step of providing a gapbetween neighbouring threads during stitching. Preferably the method also comprises thestep stitching along a path of travel of the artificial tendon of the support device. Duringflexing, especially, of a joint material will crinkle up and become bulky but when threadsare arranged with a gap they will instead just come closer or into contact but without bulging. Thus, it is a comfortable solution.
    According to an embodiment of the method, the support device is an arm support or asupporting glove, such as a strengthening glove, for supporting flexing or extending of the joint with the artificial tendon.
    According to another embodiment the method, the tunnel is provided on the inside of thesupporting device. Preferably, the tunnel is covered with a thin textile material or mesh material on the stitch side, opposite the supporting material wall.
    Application text 2015-04-29 C:UsersyvjoDesktop150429 Application text zig zag 150025SE.docx According to a second aspect of the present invention a tunnel for an artificial tendon tobe able to travel in is provided. The tunnel is positioned at a surface of a supportingmaterial of a supporting device and is formed by the supporting material and a stitchingacross the artificial tendon, the stitching comprising a low friction thread. Preferably, the stitching shows a gap between neighbouring threads.
    According to a third aspect of the present invention a strengthening glove having artificialtendons for flexing or extending at least one finger is provided. ln the strengthening glove,the tendons run in a tunnel which is positioned at a surface of a supporting material of thestrengthening glove and is formed by the supporting material and a stitching across the artificial tendon, the stitching comprising a low friction thread.
    According to an embodiment the strengthening glove is provided with a thin textile material or mesh material covering the tunnel as a lining inside the glove.
    According to another embodiment of the strengthening glove, the artificial tendon runsbetween an actuator and a fixed point through the tunnel. Preferably the tunnel is provid-ed along one side of a finger, over the top of the finger and along the other side of the finger.
    Short description of drawings Embodiments of the present invention will know be described in more detail under referral to the attached drawings, in which: Fig. 1a-c shows a flexing support for at least one joint of a finger using an artificial tendon,where different stitching methods have been used.
    Fig. 2 shows a flexing support for an arm.

    Fig. 4 shows a cross sectional view of an extending support for a finger.
    Application text 2015-04-29 C:UsersyvjoDesktop150429 Application text zig zag 150025SE.docx Detailed description of embodiments The present invention concerns a method of attaching an artificial tendon. ln Fig. 1a anartificial tendon 1 is shown running along a supporting material 2. ln use the supportmaterial 2, preferably being a part of a support device, is applied at, at least, one joint 3 of a body 4. This is preferably a human body although it is conceivable to be an animal, too.
    The artificial tendon 1 is attached at the support material 2 by means of a stitching 5crossing the tendon 1 in such a way as it is present at least on both sides of the artificialtendon 1. ln the shown embodiment a zigzag stitching 5 has been performed across theartificial tendon 1 forming a tunnel 12 for the artificial tendon 1 to run in. The tunnel 12 is made up of the support material 2 and the stitching 5, see for example Fig. 4. ln the embodiment shown in Fig. 1a a fingertip cap 6 is arranged at the fingertip and isconnected to the artificial tendon 1. The stitching 5 and thus tunnel 12 is made along thedesired path of travel for the artificial tendon 1. The artificial tendon 1 may travel alongone side of the finger up to the tip of the finger, to the cap 6 in the shown embodiment,and similarly on the opposite side of the finger. lt is also conceivable that the artificial tendon 1 runs all the way around the tip ofthe finger, without any cap.
    When a pulling force is applied to the artificial tendon 1 along its lengthwise direction ittravels through the tunnel 12 and a flexing of the finger 4 is performed. The artificialtendon 1 is connected to an actuator (not shown), which applies the pulling force. Two artificial tendons 1 are provided in this embodiment, one on each side of the finger 4. ln Fig. 1b and 1c the artificial tendon 1 runs along an edge 7 of the support material 2. lnFig.1b the thread goes from a first side of the support material 2 over the edge 7 and theartificial tendon 1 to the second, opposite side ofthe support material 2. Thus the artificialtendon 1 is more or less surrounded by the stitching 5.
    Application text 2015-04-29 C:UsersyvjoDesktop150429 Application text zig zag 150025SE.docx ln Fig. 1c the artificial tendon 1 is surrounded, more or less, at a distance of a stitch, atevery stitch. This can be accomplished by using a straight stitching where the artificialtendon 1 is one of the two threads of the straight stitching. lf the artificial tendon 1 is tootight and the other thread too loose, the thread will be forced up on the same side of thesupport material 2 as the artificial tendon 1 instead of meeting at the middle, inside of thematerial, forming a loop 8 around the artificial tendon 1. ln such a way the artificial tendon 1 may run in tunnel 12 of loops 8 along the stitching. lf the threads in the stitching 5 is provided with a gap between neighbouring threads thestitching 5 will not become bulky when the artificial tendon 1 is pulled and the stitchingwill flex since the neighbouring threads will move towards and possibly against each other but do not have to bundle up.
    Of course it is conceivable to use different kinds of stitching, such as overlock stitching, as long as the stitching 5 forms a tunnel 12.
    The present invention may be used at a lot of different joints of a body, such as an arm, ashoulder, an ankle, a wrist, a knee. ln Fig. 2 it is shown an embodiment ofthe invention foruse with an arm joint 8. Also in this embodiment the artificial tendons 1 impart a flexing,of an arm 9 in this case. A support material 2 is provided along the outside of the arm 9and the artificial tendons 1 are fixed in a collar 10 at the wrist 11. The stitching 5 may beof any type discussed above and form a tunnel for the artificial tendon 1 to travel in when pulled. Two artificial tendons 1 are provided, one on each side of the arm 9.
    The support material 2 shown in Fig. 1-2 may suitably be arranged within a larger gar-ment, if desired. For example a jacket or a glove. I/lost of the time the stitching, formingthe tunnel, is provided on the inside of the garment. One reason is to protect the stitchingand the artificial tendon from wear and another reason is not to interrupt the design ofthe garment. When the stitching and artificial tendon is provided on the inside of thegarment it is preferred to arrange a lining made of a mesh material or a thin textile mate- Application text 2015-04-29 C:UsersyvjoDesktop150429 Application text zig zag 150025SE.docx rial, thus enhancing comfort and minimizing the risk of catching the stitching with, for example, a nail. ln Fig. 3 a case of extending a joint of a body is shown. The stitching 5 is of course ar-ranged inside a glove or the like but for reason of clarity the glove is left out of the figure.The artificial tendon 1 runs in the tunnel formed by the stitching 5 and the glove (notshown) and when a pulling force is applied to the tendon 1 the finger will extend. Theartificial tendon 1 runs along the dorsal side of the finger around the tip of the finger and back along the dorsal side of the finger, through the tunnel. ln Fig. 4 a cross sectional view of a support material 2 or a glove finger and the stitching 5, which forms a tunnel 12 for the artificial tendons 1 to run through.
    The invention is described by means of embodiments but can be altered in many ways within the scope ofthe appended claims.
