    Summary:
    Safety harness device (1) for catching a person in the event of a fall, particularly during construction work, with at least one shoulder belt (2), which has a chest section (2a), a shoulder section (2b) and a back section (2c), with a locking element (6) for the detachable attachment of a fall protection line (7), the locking element (6) between a working position in which the locking element (6) is arranged on the side of the back section (2c) of the shoulder belt (2) and a catch position in which the locking element ( 6) is arranged on the side of the chest section (2a) of the shoulder strap (2), can be transferred.
    (Fig. 1) / 18
    The invention relates to a safety belt device for catching a person in the event of a fall, in particular during construction work
    at least one shoulder strap which has a chest section, a shoulder section and a back section,
    - A locking element for detachable attachment of a fall line.
    Such a safety harness with a locking and holding device is known for example from DE 200 22 993 U1. The full body harness has a seat belt strand and a shoulder belt strand. The shoulder belt strand has two sections which are arranged crosswise on the back of a wearer. This point of intersection carries a catch eye to which a catch rope can be attached.
    Standard safety harnesses are used for construction work, in which the fall protection line is attached to a safety eye in the back area of the carrier. As a result, the wearer of the safety harness is not hindered when performing the work. However, this version has the serious disadvantage that the carrier has to be released within a very short time in the event of a fall into the fall arrest line. The back suspension can lead to life-threatening stress after a short dwell time. With an exercise time of 20 minutes, death may already occur. The reason for this is that the back suspension, due to its own body weight, puts a high pressure on the chest, the arteries and leg veins, which greatly impairs breathing and blood circulation.
    On the other hand, safety harnesses are known for other applications, in particular climbing harnesses, in which the tether is attached to the front or chest side of the carrier, which increases the non-lethal dwell time “in the rope” after a crash to at least 60 minutes. However, this design would not be useful in building construction, since a chest suspension of the tether would disturb the freedom of movement of the wearer's arms in such a way that efficient work would not be possible.
    / 18th
    Accordingly, the object of the present invention is to eliminate or at least alleviate disadvantages of the prior art. The aim of the invention is therefore in particular to provide a safety harness device for building works which improves the load on the wearer in the event of a fall.
    This object is achieved by a safety belt device as specified in claim 1. Preferred embodiments are contained in the dependent claims.
    According to the invention, the locking element can be transferred between a working position in which the locking element is arranged on the side of the back section of the shoulder belt and a catch position in which the locking element is arranged on the side of the chest section of the shoulder belt.
    In order to enable free and unimpeded working, the locking element is arranged in the working position on the back of a carrier of the harness device. This is the one connected to the locking element
    End section of the fall arrest line in the back area of the carrier when building work is carried out, for example on a metal frame. In other words, a back suspension of the fall arrest line (i.e. an arrangement of the fall arrest line on the back section of the shoulder strap) is provided in the working position. This enables free and undisturbed work, while at the same time the required fall protection is achieved. In the event of a fall, the self-relocating locking element is triggered from the working to the catching position. During the transition from the working position to the catching position, the locking element and thus also the fall protection line is guided from the back of the carrier to the chest side or front of the carrier. The fall arrest line is arranged in this position on the front or chest side of the carrier. The course of movement of the locking element or the associated end region of the fall arrest line is accordingly carried out from the back of the wearer, preferably over his shoulder to the chest area. Advantageously, the chest cage of the wearer is exposed to only a minimal load by the chest suspension in the catching position. Since the fall arrest line is transferred from an arrangement on the back to an arrangement in the chest area during or a few seconds after a fall, the wearer can remain in the fall arrest line much longer before a health-endangering load of pressure forces occurs. Advantageously, the freedom of movement when carrying out the work can therefore be combined with greater safety in the event of a fall.
    For the purposes of this disclosure, the location and direction information relate to the intended use condition of the safety harness. For example, "front", "front" etc. refer to the wearer's chest area and "back", "back" etc. refer to the wearer's back area.
    In order to enable the displacement of the locking element from the back to the front of the person to be secured, a catch element on the side of the chest portion of the shoulder strap and a connecting element, preferably a connecting cable, are preferably provided for connecting the locking element to the catching element. The collecting element is on the front, i.e. on the side of the chest section of the shoulder strap. For example, an eyelet can be provided as a catch element, which is connected in particular to the chest section of the shoulder strap. The connecting element is connected on the one hand to the catch element on the front of the carrier and on the other hand to the locking element which is in the working position on the back of the carrier. A connecting cable is preferably provided as the connecting element, which for the purposes of this disclosure also includes a belt, a band or another longitudinal element that can be deformed transversely to the longitudinal direction. In the event of a fall, the locking element is displaced from the back to the front of the carrier by the longitudinal force via the fall arrest line, so that the weight of the carrier is absorbed by the catch element on the front.
    / 18th
    For this purpose, one end of the connecting element is preferably connected to the locking element and the other end of the connecting element to the collecting element. In the working position, the connecting element is in a state that is not loaded by the weight of the carrier of the safety harness, the weight of the carrier being absorbed by the locking element on the rear. In the secured position, the connecting element is in the loaded state, the weight of the carrier being absorbed by the catch element on the front or chest side.
    In order to offer the wearer maximum freedom of movement, to achieve high safety standards and to make it easier to put on the shoulder belt, it is favorable if the connecting element is guided along the shoulder belt in the working position at least in sections, preferably essentially over the entire longitudinal extent of the connecting element.
    For the reasons mentioned above, it is also advantageous if the connecting element is accommodated in the working position between the shoulder belt and a cover part, in particular a cover fabric.
    According to a preferred embodiment, the cover part is connected to the shoulder belt via a joint connection, in particular via a seam. This can delay the movement of the suspension from the back to the front in the event of a crash. Advantageously, the weight of the wearer is transferred relatively gently from the back to the chest in the event of a fall. At the end of the fall process, the wearer is suspended from the fall protection line in a stable position that does not significantly impair breathing and blood supply.
    According to a further preferred embodiment, a holding element for connecting the locking element to the shoulder strap and a release device for releasing the
    Locking element provided by the holding element. The holding element is fixedly connected to the shoulder strap, in particular to its back section, on the back of the carrier. The triggering device causes the locking element to be released from the holding element in the event of a fall by the catching forces. As a result, the weight of the carrier is transferred to the collecting element on the front.
    In a preferred embodiment variant, the release device has a bolt and a bolt receptacle, the bolt being connected to the bolt receptacle in the working position and the bolt being able to be transferred into a release position released from the bolt receptacle by applying a predetermined longitudinal force to the locking element. In the normal case, the fall protection line is therefore arranged on the locking element on the back of the carrier, so as not to disturb the carrier when performing its work. Only in the event of a crash is the triggering device activated, with which the locking element is released from the holding element, in order to enable the locking element to be displaced onto the front side.
    From a constructional point of view, it is advantageous if the bolt is in particular pivotally mounted on the holding element, the locking element having the bolt receptacle. However, the bolt can also be provided on the locking element and the bolt receptacle on the holding element.
    In order to determine a certain triggering force, it is advantageous if the triggering device has a spring element, against the spring force of which the locking element can be released from the holding element.
    The triggering device particularly preferably has a damping element for braking a triggering movement of the locking element relative to the holding element. The damping element causes a time delay in the triggering process.
    The invention is explained in more detail below on the basis of a preferred exemplary embodiment, to which, however, it should not be restricted. The drawing shows:
    Figure 1 shows the back of a wearer of a safety harness device according to the invention with a shoulder strap and leg loops in / 18 of the working position, a fall protection line for the unimpeded execution of building work is suspended on a locking element on the back of the wearer.
    2 shows the front of a wearer of the safety harness device in the working position, a catch element in the chest area of the wearer being connected to the locking element via a connecting cable;
    Fig. 3a shows a detailed view of the back suspension of the fall line in the working position, wherein the locking element with a holding element on the back portion of the
    Shoulder strap is locked; and
    3b shows a detailed view of the locking element during the triggering process in the event of a fall into the safety belt.
    Fig. 1 shows the back, Fig. 2 shows the front of a building worker who is secured with a harness 1 for catching a fall. The harness device 1 has two shoulder straps 2, each with a breast section 2a, a shoulder section 2b and a back section 2c. The breast section 2a, shoulder section 2b and back section 2c are designed in one piece in this exemplary embodiment. The back sections 2c and the chest sections 2a of the shoulder straps 2 are each arranged crosswise. For better stabilization, the back sections 2c are connected via a cross section 3. The safety harness device 1 also has two leg straps 4, which are designed as loops for the left and the right leg. The leg straps 4 are firmly connected to the shoulder strap 2 at connection points 5. Alternatively, leg straps 4 and shoulder straps 2 can also be designed in one piece. The safety harness device 1 has a locking element 6 for the detachable attachment of a fall line 7. The locking element 6 is detachably connected to one end of the fall arrest line 7, the other end being fastened to a scaffold support 8. The attachment to the scaffold support 8 takes place via a fastening ring 9, which in the embodiment shown can be pushed along the longitudinal extension of the scaffold support 8 ver7 / 18.
    As far as the harness device 1 is fundamentally known in the state of the art, it is not necessary to provide further details. The known elements of the safety belt device 1 are shown only schematically in the drawings.
    It is essential for the illustrated embodiment of the safety harness device 1 that the locking element 6 for the fall protection line 7 between a working position in which the locking element 6 is arranged on the side of the back section 2c of the shoulder belt 2 (FIG. 1) and a safety position in which the locking element 6 is arranged on the side of the breast section 2a of the shoulder belt 2, can be transferred.
    For this purpose, the shoulder strap 2 has a catch element 22 on the side of the breast section 2a. The collecting element 22 is designed, for example, as a collecting eye according to the standard DIN EN361: 2002. The collecting element 22 is connected to the locking element 6 via a connecting element 11. In this exemplary embodiment, the connecting element 11 is a connecting cable 11 a, which is guided along the shoulder belt 2 in the working position. The connecting cable 11a is received between the shoulder belt 2 and a cover part 12, in this case a cover fabric. The cover part 12 is connected to the shoulder belt 2 via a joint connection, in particular via a seam 13. When the safety belt device 1 changes from the working position to the safety position due to a fall, the locking element 6 is guided along the shoulder belt 2 from its back section 2c to its chest section 2a. During this transition, the seam 13 tears successively, starting at the back section 2c, as a result of which the connecting cable 11a is released and moves together with the locking element 6 in the direction of the chest section 2a. In the catch position, the connecting cable 11a is completely released and is no longer accommodated between the shoulder belt 2 and the cover part 12. In the catching position, the fall protection line 7 is connected to the locking element 6 and the connecting cable 11a
    Catch element 22 connected to the chest section 2a of the shoulder strap 2. The fall arrest line 7 is accordingly arranged in the catching position on the chest side of the carrier. The wearer hangs with his back down and his chest up in the rope.
    As can be seen from FIGS. 3a and 3b, a holding element 10 connects the locking element 6 to the shoulder belt 2. The holding element 10 is firmly connected to the back section 2c of the shoulder belt 2 via a holding opening 10a.
    A release device 14 is provided for releasing the locking element 6 from the holding element 10. The trigger device 14 has at least one rotatably mounted bolt 15; in the embodiment shown, two corresponding bolts 15 are provided. The locking element 6 has a (in the embodiment shown two) matching bolt receptacle (s) 16, each bolt 15 being accommodated in the associated bolt receptacle 16 in the working position (cf. FIG. 3a). The bolt 15 can be transferred by applying a predetermined longitudinal force to the locking element 6 in the event of a fall into a release position released from the bolt receptacle 16 (see arrow 20 in FIG. 3b). In the embodiment shown, the bolts 15 are pivotally mounted on the holding element 10. Due to the effect of the longitudinal force in the direction of arrow 20 on the locking element 6, the bolts 15 are pivoted. The triggering device 14 also has a spring element 21, against the spring force of which the locking element 6 can be detached from the holding element 10. The spring force defines the force that must be applied in order to release the locking element 6 from the holding element 10. In the embodiment shown, the holding element 10 has a first part 19a with the holding opening 10a which is fixedly connected to the belt element 2 and a second part 19b which is displaceably mounted in relation to the first part 19a. The spring element 21 is arranged between the first part 19a and the second part 19b in such a way that the spring element 21 is compressed when the locking element 6 is pulled as a result of the impact, until the bolts 15 are released from the bolt receptacles 16.
    After removing the locking element 6 from the holding element 10, the spring element 21 returns to its relaxed starting position.
