[0001] Band closure
[0002] The invention relates to a fastening belt with a first belt section, with a second belt section and with a fastening unit for connecting the first belt section to the second belt section in a relative position in the longitudinal direction_L to one another, wherein the fastening unit has at least one closing part and a first closing part which can be brought into positive or non-positive engagement with one another, wherein the closing part is fastened to the first belt section and the first closing part is fastened to the second belt section.
[0003] The invention also relates to a fastening belt with a fastening unit and to a system consisting of a head protection or a helmet with a fastening belt.
[0004] Fastening belts such as those described in DE 202016 100 296 U1 are already known, in which the two belt sections are connected with a fastening unit. A locking part is attached to one belt section and a locking part to the other belt section. The locking part and one locking part are brought into a positive fit for closing.
[0005] The invention is based on the object of designing and arranging a closure unit in such a way that flexible use is ensured.
[0006] The object is achieved according to the invention in that a second closure part is provided which is fastened to the second belt section in addition to the first closure part, wherein the second closure part a) can be brought into force-locking or form-locking with the closure part as an alternative to the first closure part or b) can be brought into force-locking or form-locking with a second closure part as an alternative to the first closure part, wherein i) in both cases the first belt section and the second belt section maintain the same relative position in the longitudinal direction_L or ii) at least in case a) the first belt section and the second belt section have different relative positions to one another in the longitudinal direction_L. This ensures that the closure belt is optionally equipped with at least two different closure parts which have different effects with regard to the holding force of the closure unit.The relative position of both belt sections or both belt ends in the longitudinal direction L, or their respective positions P1, P2 in the closed state, can be maintained. Alternatively, at least in case a), the first belt section or the first belt end and the second belt section or the second belt end can have different relative positions in the longitudinal direction L. Thus, the fastening belt can have different lengths depending on which fastening part is used.
[0007] It can also be advantageous if the locking part and the first closure part can be brought into positive engagement with one another. A positive engagement works via the "geometric contact of two active surfaces", in this case the peripheral surface of the locking part and the connecting section of the closure part, and prevents a release movement of the closure. Releasing a positive engagement requires an additional unlocking movement, in addition to and deviating from the holding direction of the locking part or longitudinal direction_L, of the fastening strap. In this case a backward movement to unclip the connecting section and a lateral movement to detach from the locking part. In other cases of a positive engagement that needs to be released, one of the form-lock partners with the active surface is usually a shoulder, a latch or a hook, which must undergo an unlocking movement to be released.An uncontrolled or unwanted release of a form fit inevitably leads to the failure of one of the form fit partners. A force fit such as a spring preload is optionally available to hinder the unlocking movement of one of the form fit partners. In the case of a form fit, the locking strap can be shorter than in the case of a force fit described below. The locking strap can be adjusted more tightly and is subject to more body tension. Accidental opening due to the increased body tension is impossible because of the form fit. Furthermore, it can be advantageous if the locking part and the second locking part can only be brought into force fit with one another. A force fit only hinders the release movement of the lock, but does not prevent it as is the case with a form fit. In this case, there is no form fit.A force-lock connection is based on "friction between two active surfaces" caused by a normal force between two active surfaces. This is achieved by a weight force or a spring force. Release is usually accompanied by an elastic deformation of one of the force-lock partners. However, this deformation only causes the aforementioned spring force. Since the release movement in a force-lock connection is only hindered by frictional forces, release is possible without failure of one of the force-lock partners. A classic force-lock connection is achieved by a spring clamp, a so-called clip. The fastening strap can be adjusted less tightly and may experience less body tension, thus preventing accidental opening due to body tension alone.
[0008] It can also be advantageous if the first locking part and the second locking part can be connected to the locking part simultaneously. This allows the second locking part to be secured when the first locking part, which ensures the positive locking, is used. However, when the second locking part is used, the first locking part cannot be secured by hooking it into the locking part. It must be secured separately to prevent wobbling or rattling.
[0009] In this case, it can advantageously be provided that the first closure part is designed as a closed structure with a holding section and a connecting section, wherein the holding section is attached to the second strap section and the connecting section can be brought into positive engagement with the closure part. The closed structure is easy to manufacture, is robust, and can be easily hooked into the closure part. The closure part can also be designed to be simple and robust.
[0010] Of particular importance for the present invention may be if the second closure part is designed as an open structure with a holding section and a connecting section, wherein the holding section is fastened to the second strap section and the connecting section can be brought into frictional engagement with the closure part. The open structure is equally easy to manufacture, is robust, and can be easily hooked into the closure part. The closure unit can also be opened by simply pulling in the direction of the strap. The closure part can also be designed to be simple and robust.
[0011] In connection with the design and arrangement according to the invention, it can be advantageous if the positive or non-positive connection between the closing part and the respective first closure part or second closure part can be produced manually or released manually.
[0012] It may also be advantageous if the first belt section has two locking parts that are offset from one another in the longitudinal direction (L) and / or in a transverse direction (Q). Depending on the application, this can be advantageous. Furthermore, the non-engaged first locking part can be easily secured.
[0013] Further advantages and details of the invention are explained in the claims and in the description and illustrated in the figures.

[0024] According to Figs. 1a - 2b, a closure unit 1 is formed from a first closure part 1.1, a second closure part 1.2, and a closing part 1.3. The first closure part 1.1 has a closed structure with a holding section 1.1a and a connecting section 1.1b. The second closure part 1.2, in contrast, has an open structure with a holding section 1.2a and an open connecting section 1.2b. The closing part 1.3 is formed from a central holding part 1.3d and three holding cheeks 1.3a, 1.3b, 1.3c.
[0025] According to the embodiment shown in Fig. 3a, the first closure part 1.1 is sewn via the holding section 1, 1a into a loop 2.2a of a closure belt 2 or its second belt section 2.2. The closing part 1.3 is connected to the closure belt 2 or its first belt section 2.1. The first belt section 2.1 is in a position P1 and the second belt section 2.2 is in a position P2. The closure unit 1 is closed by hooking or clipping the connecting section 1.1b into the closing part 1.3. For this purpose, as can be seen in Fig. 4a, the connecting section 1.1b is clipped onto the holding part 1.3d between the holding cheeks 1.3a, 1.3b. The clipping effect is achieved by the taper 1.1c of the connecting section 1.1b. Both belt sections 2.1 and 2.2 are thus positively secured against separation due to upward or downward tension. Separation would only occur if the locking part 1.3, the closure part 1.1, or the loop 2 failed.2a or the first belt section 2.1. According to the embodiment shown in Fig. 3b, the second closure part 1.2 is also sewn via the holding section 1.2a into the same loop 2.2a of the closure belt 2 or its second belt section 2.2. The closing part 1.3 is connected to the closure belt 2 or its second belt section 2.2. The closure unit 1 is closed by hooking or clipping the connecting section 1.2b into the closing part 1.3. For this purpose, as can be seen in Fig. 4b, the connecting section 1.2b is clipped onto the holding part 1.3d between the holding cheeks 1.3a, 1.3b. The clipping effect is achieved by the taper 1.2c of the connecting section 1.1b. In contrast to the connecting section 1.1b, the connecting section 1.2b has an opening or recess 1.2d, thus forming an open structure. Both belt sections 2.1 and 2.2 are thus secured against separation by a limited upward or downward tensile force.If a maximum tensile force is exceeded, separation occurs by spreading the connecting section 1.1 b so that it slides in the radial direction, here upwards from the holding part 1.3d.
[0026] In both embodiments according to Fig. 3a, 3b, the relative position of the two belt sections 2.1, 2.2 in a longitudinal direction L remains virtually unchanged despite the change of the closure part 1.1, 1.2. Both the position P2 of the second belt section 2.2 and the position P1 of the first belt section 2.1 remain the same for both closure variants despite the change of the closure part 1.1, 1.2.
[0027] In the exemplary embodiment shown in Fig. 4a, 4b, it can be seen that both closure parts 1.1, 1.2 with the respective holding section 1.1a are sewn into the same loop 2.2a of the closure strap 2. According to Fig. 4a, only the second closure part 1.2 with the connecting section 1.2b is clipped onto the holding part 1.3d of the closure part 1.3. If a maximum tensile force is exceeded, the strap sections 2.1, 2.2 or the strap ends separate. The first closure part 1.1 hangs ineffectively in front of the closure part 1.3 or its holding cheek 1.3a.
[0028] According to Fig. 4b, both closure parts 1.1, 1.2 are clipped onto the retaining part 1.3d with the connecting section 1.1b, 1.2b. Separation of the strap sections 2.1, 2.2 or the strap ends is only possible if the first closure part 1.1 or the locking part 1.3 or the loop 2.2a or the first strap section 2.1 fails or breaks. The second closure part 1.2 has no effect in this respect. However, it can be clipped in and is thus secured.
[0029] According to the embodiment shown in Fig. 5a, the second belt section 2.2 has two locking parts 1.3, 1.4 arranged offset in the longitudinal direction L. The locking part 1.1 is hooked into the locking part 1.3, and the locking part 1.2 is clipped into the locking part 1.4. The second locking part 1.2 has no effect in this respect. However, it can be clipped in and is thus secured.
[0030] According to the embodiment shown in Fig. 5b, only the closure part 1.2 is clipped into the locking part 1.4. Thus, both strap sections 2.1 and 2.2 are only connected by force. When a maximum force is reached, the locking unit 1 opens. However, the closure part 1.1 only rests against the locking part 1.3 from the outside (here on the left) and is ineffectively secured by the strap section 2.2.
[0031] The fastening belt 2 can also be a holding belt, a fastening band or a holding rope or the like, whereby not only a belt section 2.1, 2.2, but also a belt end or a band end or a rope end can be connected.
[0032] According to the embodiment shown in Fig. 6, the first belt section 2.1 has two locking parts 1.3, 1.4, which are offset from one another in a transverse direction_Q transverse to the longitudinal direction_L. An additional offset of the locking part 1.4' in the longitudinal direction_L would also be conceivable, as shown in dashed lines. In order for the relative position in the longitudinal direction_L between the two belt sections 2.1, 2.2 or their positions P1, P2 to be the same for both closure variants, the first locking part 1.1' would also have to be additionally offset in the longitudinal direction_L, as shown in dashed lines. However, if the first locking part 1.1 is used without extension together with the locking part 1.4', the locking belt can be adjusted more tightly due to the existing form fit and experience more body tension.
