WO 2013 / 037 470 A1 reveals a seatbelt presenter for a vehicle's seatbelt system. From the DE 10 2009 009 906 A1 A seatbelt buckle or belt presenter with a housing is known. DE 10 2005 029 139 A1 A motor vehicle known from the above is characterized by a body and at least one side wall, which has a rigid outer side wall attached to the body and functional assemblies. Furthermore, the DE 11 2012 000 863 B4 a control unit for a seatbelt positioning device. Furthermore, the DE 41 40 237 C1 A retractable belt guide for a three-point safety belt is known to exist. DE 199 01 276 A1 reveals a device for attaching the seat belt in a motor vehicle.

The object of the present invention is to provide a belt presenter for a vehicle seat belt, a seat belt for a vehicle and a vehicle, such that a belt presenter of the seat belt can be provided particularly advantageously.

This problem is solved according to the invention by a belt presenter with the features of claim 1, by a safety belt with the features of claim 4, and by a vehicle with the features of claim 7. Advantageous embodiments of the invention are the subject of the dependent claims.

A first aspect of the invention relates to a belt presenter for a seat belt of a vehicle, the interior of which, also referred to as the passenger compartment, passenger space, or cabin, is formed by a structure designed, for example, as a self-supporting body. This means that the vehicle, preferably designed as a motor vehicle, in particular as a motor car, and most especially as a passenger car, in its fully manufactured state, has the seat belt and the belt presenter, and in particular the aforementioned structure and the interior, wherein the seat belt and the belt presenter are preferably arranged in the interior. In particular, the vehicle, in its fully manufactured state, also has a seating arrangement, in particular arranged in the interior, which has, in particular, at least or exactly, one seat for a person, also referred to as an occupant. This means that the person can sit in the interior on the seat and thus on the seating arrangement. For example, the seating arrangement is a single seat, also referred to as a vehicle seat. The seat belt is assigned to the seating arrangement so that the person sitting on the seat and thus on the seating arrangement can fasten their seat belt. Consequently, in the event of a vehicle accident, the person can be restrained by the seat belt, thus limiting any excessive forward displacement of the person in the longitudinal direction of the vehicle resulting from the accident. The seat belt is therefore a restraint system that can at least limit any forward displacement of the person seated and secured by the seat belt in the longitudinal direction of the vehicle, particularly in the longitudinal direction of the vehicle. Preferably, the seat belt is designed as a three-point seat belt. The seat belt has a particularly flexible, and therefore, when considered on its own, supple webbing, which is attached to the vehicle body at a first point. At a second point, spaced apart from the first, the webbing is redirected, for example, by means of a deflection element attached to the vehicle body, so that the webbing is also attached to the vehicle body at the second point. The safety belt, for example, also has a first locking element coupled to the webbing, which is designed, for example, as a tongue. The safety belt also has a second locking element corresponding to the first, which is, for example, a buckle. The buckle is attached to the structure at a third point, spaced apart from both the first and second points. The first locking element can be coupled to the second locking element, particularly in a non-destructive and/or positive-locking manner, especially by inserting the tongue into the buckle. By coupling the first locking element to the second, the first locking element, and via the first locking element the webbing, are attached to the structure at the third point, thus providing particularly effective restraint for the person. In particular, the first locking element is coupled to the webbing in such a way that it is displaced along the webbing and relative to it in the longitudinal direction of the webbing. This allows the webbing to be adapted particularly advantageously to the external dimensions of the person, so that the person can be restrained particularly effectively by means of the safety belt.

The belt presenter has a presentation arm, also referred to as a presentation arm or simply as an arm, which is translationally movable relative to a base element of the belt presenter along a movement axis for presenting the seat belt webbing from a stowed position to at least one presentation position, also referred to as a presentation position. Most preferably, the movement axis is straight. In particular, the presentation arm is translationally movable along the movement axis relative to the base element between the stowed position and the presentation position. By moving the presentation arm from the stowed position to the presentation position, at least a portion of the webbing can be moved, for example, into such an advantageous position relative to the base element and, in particular, relative to the seat assembly, that the person, while seated, can easily, comfortably, and ergonomically grasp at least the portion of the webbing located in the aforementioned position. As a result, the person can, for example, easily, comfortably, and ergonomically move the webbing and thereby, for example, couple the first locking element with the second locking element, allowing the person to fasten their seatbelt easily, comfortably, or ergonomically. After, for example, the reach arm has been moved translationally from the stowed position to the reach position relative to the base element along the axis of movement, in order to move at least that part of the webbing into the aforementioned position and thus advantageously reach the person in the seat, i.e., present the webbing, the reach arm is, for example, moved translationally along the axis of movement relative to the base element, specifically again, from the reach position to the stowed position, specifically back again. For example, if the person unbuckles their seatbelt after a ride, i.e., releases the first and second locking elements and then simply lets go of the strap, the strap is moved, in particular pulled back, by means of a return element, such as a roller, so that the strap returns to a starting position, from which, for example, at least the aforementioned part of the strap can then be particularly advantageously handed to the person again, i.e., presented, by moving the handing arm, in particular, from the stowed position back into the handing position.

In order to make it particularly advantageous to hand over at least part of the seatbelt to the person using the belt presenter, so that the person can fasten their seatbelt easily, comfortably, and ergonomically after, for example, entering the interior and sitting down, the invention provides that the presenting arm is fork-shaped at its end, particularly its free end, for handing over the seatbelt. This means that the presenting arm has a fork head with, in particular, at least or exactly, two fork tines at its free end for handing over the seatbelt: a first fork tine and a second fork tine. The fork tines are pivotally coupled to each other about a pivot axis perpendicular to the axis of movement. This means that the fork tines can be pivoted relative to each other about the pivot axis perpendicular to the axis of movement while they are pivotally coupled to each other. The characteristic that the pivot axis is perpendicular to the axis of motion means, in particular, that the pivot axis is perpendicular to a first plane and the axis of motion is perpendicular to a second plane, the planes being perpendicular to each other. Specifically, the pivot axis intersects the axis of motion.

Because the fork tines are coupled together around the pivot axis so that they can pivot relative to each other, they can be pivoted away from each other around the pivot axis when the reach arm moves from the stowed position to the reach position, thus opening them and moving them from a closed to an open position. In the open position, the webbing can be supported against the fork tines to reach the reach arm, or at least to move part of it into the aforementioned position, and can therefore move along the axis of movement with the reach arm. In other words, when the reach arm is moved translationally from the stowed position to the reach position along the axis of movement relative to the base element, the fork tines, initially in the closed position, are pivoted away from each other around the pivot axis and thus moved from the closed position to the open position. With the fork tines in the open position, the webbing is then attached to the reach arm as it continues to move into the reach position. The fork tines, which are in the open position, are supported, causing the webbing to move along the axis of movement with the reach arm as it is moved further into the reach position. This moves at least the portion of the webbing into the position where the person seated can easily, ergonomically, and comfortably grasp it.

Because the fork tines are coupled together around the pivot axis so that they can pivot relative to each other, they can be pivoted towards each other around the pivot axis when the reach arm is moved from the stowed position to the reach position, thus moving from the open to the closed position. In other words, after at least part of the webbing has been moved into the aforementioned position by means of the reach arm, and especially after the person has grasped the webbing and, for example, coupled it to the second locking element, the reach arm is moved from the reach position back to the stowed position. During this movement, the fork tines, which were initially in the open position, pivot towards each other, thus moving from the open to the closed position, allowing the reach arm to be stowed in a space-saving manner. In other words, the reach arm occupies very little space in the stowed position, since the fork tines are in the closed position.

The hand-operated seatbelt aid is a belt-operated element that allows the seatbelt to be conveniently presented to the person seated, enabling them to fasten their seatbelt easily, comfortably, and ergonomically. Furthermore, in its stowed position, with the fork tines closed, the hand-operated seatbelt aid is particularly space-saving and can therefore be stored efficiently. Specifically, the open position is designed to coincide with the hand-operated position, so that the fork tines are preferably in the open position when the hand-operated seatbelt aid is in the hand-operated position. It is also preferably designed that the closed position is designed to coincide with the stowed position, so that the fork tines are preferably in the closed position when the hand-operated seatbelt aid is in the stowed position.

The advantageous design of the feed arm allows for a particularly advantageous dimensional chain, especially in the transverse direction of the vehicle and/or with a closed cover, compared to conventional solutions. The invention avoids undesirable, unfavorable gaps in the field of vision. Furthermore, a particularly cost-effective and space-saving design of the seatbelt presenter can be achieved. Another advantage of the invention is that the seatbelt presenter can be positioned outside the passenger's field of vision, thus creating a favorable visual impression of the interior. Additionally, the seatbelt presenter exhibits advantageous noise characteristics, as excessive noise that might be audibly perceptible to occupants can be avoided.

For example, the belt dispenser has a drive motor, preferably an electric motor, by means of which the dispensing arm can be driven and thus moved from the stowed position to the dispensing position and from the dispensing position to the stowed position. The dispensing arm is, for example, coupled to the drive motor via a rack and pinion, so that the dispensing arm can be driven by the drive motor via the rack and pinion.

To enable particularly easy and quiet movement of the fork tines from the open to the closed position, and thus achieve a particularly cost-effective design and especially advantageous noise characteristics of the belt feeder, the invention provides that the base element has two surfaces, also referred to as actuation surfaces, which are positioned opposite each other along an arrangement direction perpendicular to the direction of movement and are, in particular, spaced apart from each other and, in particular, facing each other. The actuation surfaces define a receptacle along the arrangement direction, in particular directly, with the fork tines being at least partially received in the receptacle in the stowed position. The actuation surfaces converge in a direction coinciding with the axis of movement in which the feeder arm can be moved or is moved from the feeder position to the stowed position, so that the receptacle tapers in this direction. The receptacle is thus, for example, wedge-shaped or funnel-shaped. It is conceivable that the respective actuation surface extends in a plane, with the planes converging in the aforementioned direction. Furthermore, it is conceivable that the respective actuation surface is curved or arc-shaped, with, for example, a first tangent plane tangential to the first actuation surface and a second tangent plane tangential to the second actuation surface converging in the aforementioned direction. Because the actuation Since the actuating surfaces converge in the aforementioned direction, causing the receptacle to taper in that direction, the fork tines slide directly off the actuating surfaces during any movement of the reach arm from the reach position to the stow position relative to the base element and thus relative to the actuating surfaces. This movement of the fork tines from the open to the closed position is achieved by the actuating surfaces. In other words, the fork tines are moved, or can be moved, from the open to the closed position by means of the actuating surfaces. The fork tines can therefore be easily moved from the open to the closed position by moving the reach arm, particularly by means of the drive motor, from the reach position to the stow position. An additional, separate motor for moving the fork tines from the open position to the closed position, or any other separate, additional drive for moving the fork tines from the open position to the closed position, can thus be avoided, enabling a particularly cost-effective, space-saving and weight-efficient design of the belt feeder.

To achieve a particularly cost-effective design and especially good noise characteristics of the belt feeder, one embodiment of the invention provides that the belt feeder has a spring element, preferably designed separately from the feed arm and thus separately from the fork tines, and preferably as a solid body. The spring element is tensioned by a movement of the fork tines from the open to the closed position, whereby the spring element provides a spring force, at least indirectly, and in particular directly, acting on the fork tines, at least in the closed position, by means of which the fork tines can be moved from the closed to the open position.

It has proven particularly advantageous to connect the spring element directly to the fork tines. This allows for a particularly space-saving design of the belt feeder. Furthermore, excessive dimensional tolerances and unwanted noise can be avoided.

A second aspect of the invention relates to a safety belt for a vehicle, in particular for a motor vehicle, with a belt presenter according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa.

To enable the seat belt webbing to be presented particularly advantageously by means of the belt presenter, one embodiment of the second aspect of the invention provides that the seat belt webbing has two opposing broad sides, between which two opposing narrow sides of the webbing are arranged. It is preferably provided that, in the presenting position in which the fork tines are in the open position, one of the broad sides is directly supported against the fork tines and faces them, particularly along the axis of movement, while the other broad side points away from the fork tines, particularly along the axis of movement. This allows the presenting arm to move the webbing into the aforementioned position particularly advantageously, so that the webbing can be presented particularly advantageously. Consequently, the person can fasten their seat belt easily, comfortably, and ergonomically.

In order to be able to supply the webbing particularly advantageously by means of the webbing feeder, in a further embodiment of the second aspect of the invention it is provided that in the supply position at least a respective partial area of the respective broad side runs in a respective plane, also referred to as the side plane, which extends perpendicular to the axis of movement.

A third aspect of the invention relates to a vehicle, preferably designed as a motor vehicle, in particular as a motor car and most especially as a passenger car, which has at least one safety belt according to the second aspect of the invention. Advantages and advantageous embodiments of the first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the third aspect of the invention and vice versa.

1 shows in a schematic perspective view a belt presenter 1, also referred to as a belt presenter, for a safety belt 2 ( 4 ) of a vehicle, whose interior space 3, also referred to as passenger compartment, passenger space or cabin, is formed by a vehicle structure designed, for example, as a self-supporting body. The interior space contains the seat belt presenter 1, the seat belt 2 and at least one seat assembly, wherein the seat assembly, in particular at least or exactly, has a seat for a person, also referred to as an occupant. The seat belt 2 is arranged in relation to the seat assembly and the seat, so that the person sitting in the seat and thus on the seat assembly can fasten their seat belt 2. Consequently, the person can be restrained by means of the seat belt 2, for example, in the event of an accident involving the vehicle.

The belt presenter 1 has a hand-delivery arm 4, which is used for handing over, that is, for handing over a belt 5 ( 4 ) of the seat belt 2 from a in 1 shown storage position V in at least one in 5 The presented delivery position A is translationally movable relative to a base element 6 of the belt presenter 1 along a movement axis 7. The movement axis 7 is straight and thus runs along an imaginary straight line. The safety belt 2 is designed as a three-point safety belt. The delivery arm 4 can be translationally moved, i.e., moved back and forth, along the movement axis 7 relative to the base element 6 between the stow position V and the delivery position A. 1 An arrow 8 illustrates a first direction of movement, also referred to as the first direction of movement, which coincides with the axis of movement 7, whereby the reaching arm 4 can be moved in the first direction of movement from the stowed position V to the reaching position A. In other words, the reaching arm 4 is moved in the first direction of movement relative to the base element 6 in order to move the reaching arm 4 from the stowed position V to the reaching position A. The first direction of movement coincides with the axis of movement 7. An arrow 9 illustrates a second direction of movement, also referred to as the second direction of movement, which coincides with the axis of movement 7 and is opposite to the first direction, in which the reaching arm 4 can be moved relative to the base element 6 from the reaching position A to the stowed position V. In other words, in order to move the reaching arm 4 from the reaching position A to the stowed position V along the axis of movement 7 relative to the base element 6, the reaching arm 4 is moved in the second direction of movement.

The basic element 6 is or comprises, for example, a trim element that has, for instance, an outer skin 10, which is perceptible both haptically and visually to the person sitting in the seat and thus in the interior 3, meaning it can be directly touched and seen. For example, the trim element is a side panel.

In order to make the belt 5 particularly advantageous to hand over by means of the belt presenter 1, i.e., to make it possible for the person in the seat to fasten their seatbelt 2 particularly easily, comfortably and ergonomically, the presenting arm 4 has a fork head 11, in particular exactly two fork tines, namely a first fork tine 12 and a second fork tine 13, at its end E, which is free. The fork tines 12 and 13 are pivotably coupled to each other about a pivot axis S extending perpendicular to the axis of movement 7. The presenting arm 4 has a base body, in this case designed as a rod 14, wherein, for example, the fork tines 12 and 13 are designed separately from each other and each separately from the base body (rod 14). The respective fork tines 12 and 13 are pivotably coupled to the base body about the pivot axis S relative to the base body, such that the fork tines 12 and 13 can pivot about the pivot axis S relative to each other and relative to the rod 14. Because the fork tines 12 and 13 are pivotally coupled to each other about the pivot axis S, they can pivot away from each other about the pivot axis S during any movement of the reach arm 4 from the stowed position V to the reach position A, and thus from a position that is in 1 shown closed position GS in a 4 The open position OS shown is movable, in which the webbing 5 can be supported on the fork tines 12 and 13, in particular directly, for reaching the webbing 5, and thus moved along the axis of movement 7 with the reaching arm 4. This is achieved by the fact that the fork tines 12 and 13 can be pivoted relative to each other about the pivot axis S. The fork tines 12 and 13, being coupled together, can be pivoted towards each other about the pivot axis S during a respective movement of the reaching arm 4 from the stowed position V to the reaching position A and can thus be moved from the open position OS.

The belt presenter 1 has one in 1 The drive motor 15, which is shown particularly schematically and is designed, for example, as an electric motor, is used to drive the rod 14 and, via the rod 14, the reaching arm 4, whereby the reaching arm 4 can be driven translationally along the axis of movement 7 relative to the base element 6 between the storage position V and the reaching position A, and thus can be moved from the storage position V to the reaching position A and again from the reaching position A to the storage position V.

2 , 3 and 4 The respective intermediate positions of the dispensing arm 4, located between the stowing position V and the dispensing position A, are shown. For example, if the drive motor 15 is initially in the 1 When the reach arm 4, located in the stowed position V shown, is moved from stowed position V to reach position A, the reach arm 4 initially comes into the position shown in 2 shown intermediate position, then into the 3 shown intermediate position and then into the 4 intermediate position shown, whereupon the reaching arm 4 moves into the 5 The illustrated enrichment position A is shown. It can be seen that the fork tines 12 and 13, for example, are already in the 3 The intermediate position shown reaches the open position OS. Then the retrieval arm 4 is removed from the position shown. 3 The intermediate position shown is moved further towards the loading position A and finally into the loading position A, as shown. 4 u As can be seen in section 5, the webbing 5 moves along the axis of movement 7 relative to the base element 6 with the reaching arm 4. This causes, for example, at least a part T of the webbing 5 to move into a position that is 5 The position shown is moved, in which at least part T of the webbing 5 is held, at least temporarily, by means of the webbing guide 1. While at least part T of the webbing 5 is in the aforementioned position, which is shown in 5 As shown, the person seated on the seat and thus on the seating system can easily, ergonomically, and comfortably grasp at least part T of the webbing 5, so that the person can subsequently fasten their seat belt 2 easily, comfortably, and ergonomically. Following this, for example, the reach arm 4 is moved from the reach position A back to the stowed position V by means of the drive motor 15, thereby moving the fork tines 12 and 13 from the open position OS to the closed position GS.

6 A schematic top view shows the fork tines 12 and 13 according to a first embodiment of the belt feeder 1. 7 The schematic top view shows the fork tines 12 and 13 according to a second embodiment of the belt feeder 1.

Out of 6 and 7 It is evident that the belt feeder 1 has a spring element 16, designed here as a solid body and thus as a mechanical spring, which is tensioned by a respective movement of the fork tines 12 and 13 from the open position OS to the closed position GS. This spring element 16 provides a spring force, at least in the closed position GS, by means of which the fork tines 12 and 13 can be moved from the closed position GS to the open position OS, and are moved in particular when the feeder arm 4 is moved from the stowed position V to the feeder position A. In the first embodiment and in the second embodiment, the spring element 16 is directly connected to the fork tines 12 and 13.

Looks especially good 1 , 2 , 3 , 4 until 5 It is evident that the base element 6 has two actuation surfaces F1 and F2, also simply referred to as surfaces. Actuation surfaces F1 and F2 are positioned opposite each other along an arrangement direction perpendicular to the axis of movement 7, also referred to as the direction of movement. Actuation surfaces F1 and F2 are spaced apart from each other along this arrangement direction and point towards each other. Actuation surfaces F1 and F2 define a receptacle 17 along this arrangement direction, such that the receptacle 17 is bounded on both sides along this arrangement direction, directly by actuation surfaces F1 and F2. This arrangement direction is also referred to as the axis of arrangement and runs straight, i.e., along an imaginary second straight line perpendicular to the axis of movement 7. In the stowed position V, the fork tines 12 and 13 are each at least partially received in the receptacle 17. This is particularly evident from... 1 , 2 , 3 , 4 until 5 It can be seen that the recess 17 tapers in the second direction, illustrated by arrow 9 and coinciding with the axis of movement 7, in which the reaching arm 4 can be moved from the reaching position A to the stowed position V. In other words, the recess 17 tapers in the second direction, illustrated by arrow 9, in which the reaching arm 4 is moved in order to move the reaching arm 4 from the reaching position A to the connection point V. This means that the actuating surfaces F1 and F2 move towards each other in the second direction, illustrated by arrow 9 and coinciding with the axis of movement 7. The fork tines 12 and 13 slide directly off the actuating surfaces F1 and F2, particularly whenever the reach arm 4 is moved from the reach position A to the stowed position V. This causes the fork tines 12 and 13 to pivot towards each other about the pivot axis S by means of the actuating surfaces F1 and F2, moving them from the open position OS to the closed position GS. This tensions the spring element 16, so that in the stowed position V of the reach arm 4 and in the closed position GS of the fork tines 12 and 13, the fork tines 12 and 13 are held in the closed position GS against the spring force of the spring element 16 by means of the actuating surfaces F1 and F2. When the reaching arm 4 is moved from the stowed position V to the reaching position A, the spring element 16 can at least partially relax, so that, by means of the spring force of the spring element 16, the fork tines 12 and 13 are moved from the closed position GS to the open position OS during the respective movement of the reaching arm 4 from the stowed position V to the reaching position A, and thus pivoted away from each other.

At the in 6 In the first embodiment shown, the spring element 16 is, for example, designed as a helical spring. Alternatively or additionally, in the first embodiment, the spring element 16 is made of a metallic material.

At the in 7 In the second embodiment shown, the spring element 16 is formed, for example, from an elastomer, in particular from rubber, so that, for example, in the second embodiment, the spring element 16 is designed as a rubber band.

The movement of the reaching arm 4 from the stowed position V to the reaching position A is also referred to as extending the reaching arm 4. It can be seen that during the extension of the reaching arm 4, the fork tines 12 and 13, which are designed as folding parts, are pivoted away from each other by means of the spring element 16, i.e., by means of the spring force of the spring element 16, and thus spread apart, thereby moving the fork tines 12 and 13 from the closed position GS to the open position OS. As a result, the fork tines 12 and 13, and thus the fork head 11, which are in the open position OS, can grasp the webbing 5 at least substantially over its entire surface, thereby advantageously presenting, i.e., handing over, at least part T of the webbing 5 to the person in question.

The movement of the reach arm 4 from the reach position A to the stow position V is also referred to as retracting the reach arm 4. When the reach arm 4 is retracted, the fork tines 12 and 13 are pressed together by means of the actuating surfaces F1 and F2, i.e., pivoted towards each other and thereby moved from the open position OS to the closed position GS. Since the fork tines 12 and 13 slide directly on the actuating surfaces F1 and F2, these surfaces are also referred to as the contact surfaces. In the stow position V, for example, the fork tines 12 and 13 are positioned behind the outer skin 10, i.e., behind a surface of the cladding element that forms at least part of the outer skin 10, thus creating a visually appealing appearance.

The belt feeder 1, for example, has a rack (not shown in detail in the figures) via which, for example, the feed arm 4, in particular the rod 14, can be driven by the drive motor 15. For example, the rod 14 is the rack. In other words, for example, the rack is formed integrally with the rod 14, so that preferably the rod 14 and the rack are formed from a single piece. Furthermore, it would be conceivable that the rack is formed separately from the rod 14 and connected to the rod 14. The rack has a first set of teeth. The belt feeder 1 has, for example, a gear, also referred to as a pinion, with a second set of teeth corresponding to the first set of teeth, wherein the teeth mesh, for example, in particular directly. For example, the gear can be driven by the drive motor 15 and is thereby rotatable about a gear axis relative to the base element 6. The gear's axis of rotation runs, for example, perpendicular to the axis of movement 7 and, for example, perpendicular to the pivot axis S. By rotating the gear around its axis of rotation and relative to the base element 6, the rack can be driven by the gear. This driving action of the rack drives the rod 14, and thus the dispensing arm 4, allowing it to move translationally along the axis of movement 7 relative to the base element 6. This enables precise, demand-based, and quiet movement of the dispensing arm 4 between the stowed position V and the dispensing position A.

Extending the reach arm 4 allows the spring element 16 to at least partially relax, thereby pivoting the fork tines 12 and 13 away from each other and moving them from the closed position GS to the open position OS. Thus, extending the reach arm 4 causes the fork tines 12 and 13 to move from the closed position. GS is permitted in the open position OS. This ensures a simple, space-saving, weight-efficient and cost-effective design of the belt feeder 1.

Looks especially good 5 It can be seen that the webbing 5 has two opposing broad sides, namely a first broad side B1 and a second broad side B2. In the reaching position A, in which the fork tines 12 and 13 are in the open position OS, the broad side B1 lies directly against the fork tines 12 and 13 in the second direction illustrated by arrow 9, so that the broad side B1 is supported in the second direction by the fork tines 12 and 13 in the open position OS, so that the broad side faces the fork tines 12 and 13 in the second direction. In the reaching position A, the broad side B2 points away from the fork tines 12 and 13 in the open position OS in the first direction illustrated by arrow 8. Furthermore, in 5 It is evident that in the provision position A, at least a respective sub-area of the respective broadside B1, B2 runs in a respective plane that extends perpendicular to the axis of movement 7. For example, part T of the webbing 5 comprises the respective, previously mentioned sub-area of the respective broadside B1, B2.
