Description

The present invention relates to a lumbar orthosis having a first and a second portion, each having at least one connecting element, and at least one clamping system, by means of which the first and the second portion are connectable.

Such devices are known in the art and, for example, in the document WO 99/65428 disclosed. This document discloses a device with an orthosis body having two segments. To connect the two segments of the orthosis body, a cable is provided, which is connected in each case with the two segments of the body. Each segment has a set of pulleys. The cable runs around the pulleys of one segment and the pulleys of the other segment alternately. The cable is each provided with a user-operable handle. By means of the handle, a user or wearer of the device according to the document WO 99/65428 tension the cable and thus adjust the degree of support of the spine by the device. The carrier must pull on the handle to tension the cable. Then the handle is attached in the tensioned state of the cable via a hook and loop fastener on one of the two segments.

Even if a user of the device according to WO 99/65428 For example, to wear the device on successive days with the same support of the spine, it is difficult to adjust the same support, as with each new application of the device according to WO 99/65428 the cable must be stretched over the handle again. The handle connected to the cable is fixed at each actuation or each tensioning of the cable in a different position on one of the segments of the orthosis body. The need to re-actuate the cable over the handle each time the device is applied in accordance with WO 99/65428 and the support of the spine thus changing, limits the comfort of a user or wearer.

It is an object of the present invention to provide a lumbar orthosis with which the comfort of a wearer of the device can be increased.

This object is achieved with a lumbar orthosis with the features of the protection claim 1. Advantageous embodiments will be apparent from the appended subclaims.

The lumbar orthosis according to the invention has a tensioning system with at least one tensioning element which extends through the at least one connecting element of the first portion and the at least one connecting element of the second portion. For clamping the at least one clamping element at least one clamping means is provided. The at least one tensioning means remains stationary for setting a predetermined tension force in its predetermined position on at least one of the first and second portions.

According to the invention, the at least one tensioning means is a rotating mechanism. As clamping means in addition to a rotating mechanism and other mechanisms are conceivable. For example, the invention may be practiced in conjunction with a ratchet mechanism.

The rotating mechanism is connected to the at least one tensioning element such that the at least one tensioning element can be tensioned with a predetermined tensioning force by a predetermined rotational movement of the rotating mechanism. The tensioning element can be, for example, a cable, a wire, a tear-resistant cord or the like.

The rotating mechanism is further provided according to the invention with a locking device +, in which the rotating mechanism can be latched after a predetermined rotational movement. In other words, the rotary mechanism after a predetermined rotational movement in the latching device engage, so that the predetermined clamping force or the clamping state maintained, so to speak "stored" can be. As a result, a wearer of the lumbar orthosis does not have to re-actuate the tensioning system each time the device is put on. Further, a detent mechanism having a plurality of detent positions enables an increase in the tension force in predefined steps, whereby the spinal column support effect generated by the device can be adjusted stepwise.

Unlike the prior art, in which the handle for tensioning the cable must be displaced, the tensioning means according to the invention remains stationary in its predetermined position on the first section and / or the second section when setting a predetermined tension force. A wearer of the lumbar orthosis according to the invention can therefore apply and remove the device several times in succession without having to displace at least one tensioning means for tensioning the tensioning element from its predetermined position on at least one of the first and second sections. In other words, the at least one clamping means of the at least one clamping system is designed such that a predetermined clamping force on the stationary clamping means is adjustable and the set clamping force on the at least one Maintaining or maintaining the clamping means, so it remains a default. Accordingly, a wearer of the lumbar orthosis according to the invention can also resort to the predetermined tension previously set by him when the device is re-applied, without the at least one tensioning system having to be tensioned again. The wearer can thus create the device directly and carry several times with the exact same Abstützungsgrad the spine, whereby the comfort for a wearer is significantly increased.

According to one embodiment of the invention, the lumbar orthosis may comprise at least two tensioning systems. With such a lumbar orthosis, the spinal column can be supported over a larger area with the degree of support that can be set via the at least two tensioning systems. The clamping force of the at least two clamping systems can be set individually, so that, for example, the degree of support in the region of one of the clamping systems can be set higher than the degree of support in the region of the other clamping system.

The first and second portions of the lumbar orthosis may each comprise at least one stationary tensioning means. The stationary clamping means of the first section and the stationary clamping means of the second section can be arranged such that the clamping force generated by the at least one clamping means on the first section and the clamping force generated by the at least one clamping means on the second section act in the opposite direction. By the clamping forces acting in different directions of the at least one clamping means on the first section and the at least one clamping means on the second section, the clamping force over the entire extension of the lumbar orthosis or the extension of the first and the second section can be adjusted according to the wishes of the wearer . increase. This allows the device to adjust evenly when adjusting the clamping force to the body of the wearer.

The at least one tensioning means on the first portion and the at least one tensioning means on the second portion may each be arranged at a free end of the first and the second portion. In other words, the at least one clamping means of the first section and the at least one clamping means of the second section are each arranged at the end of the first and second sections opposite to the ends of the first and second sections connected via the clamping system. The arrangement of the at least one clamping means on the first section and the at least one clamping means on the second section ensures that a support of the lumbar orthosis can operate both clamping means simultaneously with one hand, so quickly and easily set a desired clamping force in both clamping systems to be able to.

According to a development of the invention, the at least one connecting element of the first and the second section can deflect the at least one tensioning element in the direction of the respective other section. The at least one clamping element alternately passes through the at least one connecting element of the first section and a connecting element of the second section, so that the at least one clamping element extends in an S-shaped manner through successive connecting elements of the first and the second section. The at least one connecting element, together with the at least one tensioning element, contributes to enabling the first section and the second section to approach one another when the at least one tensioning device is actuated by the at least one tensioning element to produce a desired degree of support of the spinal column.

According to one embodiment, the lumbar orthosis has at least one belt element. The belt member may be applied to a human body and connected to the first and second sections. The two ends of the at least one belt element can, for example, be connected to one another via a hook-and-loop fastener and fixed to the body of the wearer in this way.

The first and second sections may each comprise a connection means. The connecting means of the first portion and the connecting means of the second portion are formed corresponding to each other. The at least one connecting means of the first section and the at least one connecting means of the second section are accordingly complementary parts which can be engaged with each other to make a connection. Conceivable here are various connection closures, such as snaps or the like. The at least one connection means of the first section and the at least one connection means of the second section may each be arranged at a free end of the first section and the second section. The connecting means can be formed, for example, by a belt section and in each case a closure element of a closure system.

In addition, the clamping systems 16 . 18 and accordingly also the turning mechanisms 20 . 24 in the y direction of the lumbar orthosis 10 arranged offset to each other, wherein the rotating mechanism 20 at the section 12 in the y-direction above the rotation mechanism 24 at the section 14 is provided. In the 1 The y-axis represented corresponds in its direction to the y-axis of the human body, that is to say the longitudinal axis of the human body.

Due to the staggered arrangement of the clamping systems 16 and 18 or the rotary mechanisms 20 . 24 can the rotation mechanisms 20 . 24 from a wearer of the lumbar orthosis 10 be operated simultaneously with one hand, to a uniform and rapid as possible setting the clamping force and the Abstützgrades both clamping systems 16 . 18 to enable at the same time.

The sections 12 and 14 each have projecting arms in the direction of the x-axis 12a . 12b and 14a and 14b on, with the rotation mechanism 20 on the arm 12a and the rotating mechanism 24 on the arm 14b is provided. The poor 12a . 12b and 14a . 14b the sections 12 and 14 Each also differs by their position in the y-direction and have soft, curved outer contours.

At each of the arms 12a . 12b and 14a . 14b is in each case a connecting means 32 . 34 . 36 and 38 intended. In this case, the connecting means 32 on the arm 12a and the connecting means 36 on the arm 14a formed corresponding to each other. Likewise, the connecting means 34 on the arm 12b and the connecting means 38 on the arm 14b formed corresponding to each other.

Each of the connecting means 32 to 38 is each of a belt section 32a . 34a . 36a . 38a and a closure element 32b . 34b . 36b . 38b educated. Because the closure elements 32b and 36b such as 34b and 38b are each formed complementary to each other, form these closure elements 32b . 34b . 36b . 38b each a closure system, so that on the connecting means 32 . 36 and 34 . 38 a connection between the poor 12a . 14a and 12b . 14b will be produced. The closure elements 32b . 34b . 36b . 38b can be designed such that on the closure elements 32b . 34b . 36b . 38b the length of the belt sections 32a . 34a . 36a . 38a in accordance with a body circumference of a user or wearer of the lumbar orthosis 10 can be adjusted.

In 1 is also the belt element 40 shown to be a wearer of the lumbar orthosis 10 can invest in his body. The end sections 40a and 40b of the belt element 40 can be connected to each other, for example via a Velcro. In 1 is suggestively the Velcro element 42 at the end area 40b of the belt element 40 shown with a Velcro element (not shown) on the invisible side of the end portion 40a a Velcro connection between the two end areas 40a and 40b can produce. The belt element 40 also has tab webs 44 . 46 on, over which the sections 12 and 14 with the chord member 40 are connected. The flap webs 44 . 46 include individual tabs 44a . 44b and 46a and 46b into which the arms 12a . 12b and 14a . 14b can be inserted.

Would a user like the lumbar orthosis 10 create, he first puts the belt element 40 to his body and connects the end areas 40a and 40b of the belt element 40 via the Velcro fastener (Velcro element 42 ) in front of his body. Following this, the corresponding connection means 32 . 36 and 34 . 38 or the closure elements 32b . 34b . 36b . 38b connected in front of the body of the user or wearer, so that a connection between the arms 12a . 14a and 12b . 14b and the body of the wearer is annular from the lumbar orthosis 10 is enclosed. To adjust the tension or the desired support of the spine through the lumbar orthosis 10 the user now actuates the turning mechanisms 20 and 24 , whereby the clamping elements 22 . 26 be curious and look at the two sections 12 and 14 approach each other. As already mentioned, the turning mechanisms 20 . 24 each with one hand, ie the rotating mechanism 20 with the left hand of the user and the turning mechanism 24 with the right hand of the wearer, be operated. The turning mechanisms 20 . 24 each have a handle disc 68 . 70 ( 2 ) on which the carrier operates. Has the user by a rotational movement of the rotating mechanisms 20 . 24 set the desired support of the spine, he leaves the turning mechanisms 20 . 24 Come on. The turning mechanisms 20 . 24 maintain the state of tension or the attitude of the carrier, via a locking device (not shown), so to speak, store the user's attitude. Has a wearer once adapted to his body default setting of the clamping systems 16 . 18 made, and would like to slightly increase the support effect, just a short operation of the rotary mechanisms 20 . 24 out.

To release the latching, they can be pressed in or pulled out in the axial direction.

Would a wearer want the lumbar orthosis 10 Now wear several times with the same support attitude, he only has the belt element 40 close in front of his body and the fasteners 32 . 36 and 34 . 38 connect with each other. He has the clamping systems 16 . 18 do not press again as the rotation mechanisms 20 . 24 the respective state of tension of the clamping systems 16 . 18 have maintained. This may cause the application of the lumbar orthosis 10 be significantly simplified for wearing with the same support setting.

2 shows a schematic, partially broken away view of the sections 12 and 14 as well as the clamping systems 16 and 18 ,
