Description

[0001] The invention relates to a protective device for a vehicle interior, comprising a flexible partition mesh net that can be stretched at least largely vertically within the vehicle interior by means of tensioning members provided with suspension hooks in an upper edge region of the partition mesh net. Roof-mounted brackets, which are fastened in a roof area of ​​the vehicle interior in the ready-to-use state, are adapted to the suspension hooks to enable a positive engagement of the suspension hooks in the roof-mounted brackets. The invention also relates to a suspension hook for a partition mesh net of such a protective device.

[0002] In passenger cars (Mercedes G-Class, W 463 series), in which a cargo area within a vehicle interior transitions into a passenger compartment, it is generally known to provide a protective device with a flexible partition mesh net that can be stretched approximately vertically at a transition between the cargo area and the passenger compartment in the vehicle interior. The partition mesh net has tensioning elements on both its upper side and its lower side, which interact with vehicle-fixed brackets within the vehicle interior to stretch the partition mesh net. At opposite corners of an upper side of the partition mesh net, suspension hooks are provided, to which roof-side brackets are assigned on a roof area of ​​the vehicle interior. Each of these two suspension hooks has a support ring and a mushroom head molded onto the support ring.The support ring accommodates a strap that encloses the partition mesh. The mushroom head can be hooked into the respective roof-mounted bracket. The partition mesh is tensioned after the hooks are hooked into the roof-mounted brackets using tensioning straps that engage the lower edge of the partition mesh and interact with the floor-mounted brackets in the vehicle interior.

[0003] DE 10 2022 201 521 B4 discloses a protective device for the interior of a passenger car, in which a flexible partition mesh is wound and unwound on a winding shaft. A dimensionally stable pull-out profile is provided at the front end portion of the partition mesh in the pull-out direction. On opposite ends, the profile is provided with telescopically movable holding elements that are linearly movable relative to the pull-out profile and can be hooked into roof-mounted receptacles. The holding elements are guided inwardly or outwardly in synchronous, opposite directions by means of a cable pull system.

[0004] DE 10 2019 119 131 B4 discloses a partition net for motor vehicles for separating a cargo area in a passenger car from a passenger compartment. The partition net has net edges enclosed by a webbing. Furthermore, fastening elements near the floor and fastening hooks near the roof are provided for spanning the partition net within the vehicle interior.

[0005] DE 10 2017 219 865 A1 discloses a partition device for the interior of a passenger car, comprising a flexible partition structure. The upper end regions of the partition structure are provided with stiffening elements, to which a fastening element is mounted that can be hooked into a roof-side fastening receptacle.

[0006] DE 198 18 583 C1 describes a station wagon with rear seats in a vehicle interior. The upper end areas of the rear seat backrests are provided with a T-shaped receiving groove into which a T-shaped bracket of a roller blind housing can be inserted and locked. A roller blind is mounted in the roller blind housing, which can be wound up and unwound and releasably hung on a roof area of ​​the vehicle interior when extended upwards and separated.

[0007] The object of the invention is to provide a protective device and a suspension hook of the type mentioned at the outset, which enable a particularly simple and functionally reliable separation of a loading space from a passenger compartment within a vehicle interior of a motor vehicle.

[0008] This object is achieved for the protective device in that the suspension hooks have a T-shaped suspension head, wherein a T-web of the suspension head is provided with two web ends that lie opposite one another and protrude orthogonally in opposite directions from a hook plane of the T-shaped suspension head. The solution according to the invention prevents unintentional detachment of the suspension hooks from roof-side brackets, thus ensuring particularly reliable suspension of the partition mesh net to the roof-side brackets. The web ends of the T-shaped suspension head are aligned in opposite directions to one another in a common plane, wherein this plane is aligned orthogonally to a hook plane in which the suspension hook extends. The web ends protrude from this hook plane in opposite directions, wherein the web ends are curved or angled relative to the T-shaped suspension head.The flexible partition mesh is preferably surrounded by a webbing and has a rigid crossbar at a lower edge region, which extends across the entire width of the partition mesh. In a variant according to the invention, no rigid crossbar is provided. The partition mesh is then tensioned exclusively using tensioning elements. The solution according to the invention is particularly advantageously suitable for use in passenger cars in which a cargo area within the vehicle interior opens into a passenger compartment. When tensioned, the partition mesh separates the cargo area from the passenger compartment. The protective device according to the invention can also be used in the same way in other types of motor vehicles.

[0009] In one embodiment of the invention, each suspension hook has a support ring for receiving a strap, from which the T-shaped suspension head protrudes in the plane of the hook. The upward projection is related to a vertical orientation of the suspension hook, as the suspension head is designed for releasable fixation in the respective roof-side bracket.

[0010] In a further embodiment of the invention, the suspension head has a suspension neck protruding from the upper side of the support ring, which supports a T-shaped bar with the bar ends. The support ring, the suspension neck, and the T-shaped bar are aligned in a common plane, namely the hook plane. Only the bar ends protrude from this hook plane on opposite sides.

[0011] In a further embodiment of the invention, the web ends are aligned in a common suspension plane that is orthogonal to the hook plane. Advantageously, the T-web with its web ends is curved or angled in an S- or Z-shape, as seen in the suspension plane.

[0012] In a further embodiment of the invention, the support ring is triangular in shape with two triangular legs of different lengths, and the suspension neck protrudes upwards offset from a central longitudinal axis of the suspension hook. In contrast to the prior art, the support ring is thus designed asymmetrically to a central longitudinal axis of the suspension hook, wherein the central longitudinal axis is an axis that orthogonally intersects a hypotenuse of the triangular shape of the support ring. The suspension neck protrudes upwards at a corner where the two triangular legs merge. The suspension neck is offset parallel to the central longitudinal axis of the suspension hook. In a further variant of the invention, another triangular shape is provided for the support ring, however, not asymmetrically, but with triangular legs of equal length. Accordingly, in this variant, the suspension hook protrudes upwards coaxially to the central longitudinal axis.

[0013] In a further embodiment of the invention, the suspension hook is manufactured as a one-piece metal stamped or milled part with a square cross-section. This design enables particularly simple and cost-effective production of the suspension hook. The suspension hook is punched or milled from a steel plate. In contrast to the prior art, which required a combination of bending and welding processes to produce the suspension hook from a round profile, only a simple stamping or milling process is required, preferably supplemented by a short cold forming process in which the web ends of the T-web of the suspension head are bent out of the hook plane.

[0014] In a further embodiment of the invention, several edges of the suspension hook are rounded. This design ensures that, particularly in the area of ​​the support ring of the suspension hook, no notch effects can occur on a webbing of the partition mesh that is threaded through the support ring. The rounded edges of the suspension hook also ensure injury-free handling by an operator.

[0015] In a further embodiment of the invention, the suspension hook is provided with a plastic coating, at least in sections. This embodiment is a variation of machining the edges of the suspension hook to achieve a rounded finish. The plastic coating has the same effect by covering the sharp edges of the suspension hook with plastic, preventing damage to the webbing and preventing any risk of injury to operators.

[0016] In a further embodiment of the invention, each roof-mounted bracket is provided with a receiving mouth and a suspension slot branching orthogonally from the receiving mouth, which opens into a retaining cup. The receiving mouth accommodates the T-shaped suspension head. The suspension slot allows the suspension neck of the suspension head to slide along the suspension slot. The retaining cup ensures a positive fit of the T-bar of the suspension head on the roof-mounted bracket.

[0017] In a further embodiment of the invention, the receiving mouth is designed as a rectangular passage whose dimensions are matched to the T-bar of the suspension head in such a way that the T-bar can be inserted through the passage. When the roof-mounted bracket is fully assembled within a vehicle interior, the T-bar of the suspension head is inserted from below through the receiving mouth and moved along the suspension slot towards the holding cup, with the T-bar engaging behind the suspension slot and the holding cup, thus creating a positive fit for the suspension hook. With the correct alignment, the T-bar can also be inserted into the receiving mouth from one side.

[0018] In a further embodiment of the invention, the width of the hanging slot is matched to the width of the hanging neck to allow the hanging neck to slide along it. Thus, there is a certain amount of play between the opposite edges of the hanging slot and the hanging neck to allow the hanging neck to slide along the hanging slot.

[0019] In a further embodiment of the invention, the roof-side bracket is designed as a one-piece sheet steel part, and the receiving mouth, the suspension slot, and the holding cup are provided in the sheet steel part. The holding cup is designed in particular as a deep-drawn, circular indentation whose diameter is larger than the length of the T-bar of the suspension head. The depth of the holding cup corresponds at least to the height of the T-bar of the suspension hook in order to allow rotation of the T-bar within the holding cup for proper alignment. The protrusion of the web ends to opposite sides prevents the suspension hook from being accidentally released from the holding cup and the suspension slot.

[0020] A suspension hook can be offered and sold independently as a spare part for a protective device according to the invention. Unlike the prior art, the suspension hook enables a particularly secure connection of a barrier mesh to a roof-mounted bracket. The roof-mounted bracket adapted to the suspension hook can also be offered and sold independently as a spare part for a protective device according to the invention.

[0021] Further advantages and features of the invention emerge from the claims. A preferred embodiment of the invention is described below and illustrated with reference to the drawings. Fig. 1 shows a preferred embodiment of a protective device according to the invention in a schematic representation, Fig. 2 shows an enlarged view of an embodiment of a suspension hook according to the invention for a protective device according to Fig. 1, Fig. 3 the hook after Fig. 2 in a side view, Fig. 4 the hook according to the Fig. 2 and Fig. 3 - in an enlarged view - in a plan view, and Fig. 5 shows a schematic, perspective view of a part of the protective device according to Fig. 1, by moving the hook according to the Fig. 2 to 4 is hooked into a roof-side bracket of the protective device.

[0022] A protective device 1 according to the Fig. 1 to 5 is intended for separating a cargo space from a passenger compartment within a vehicle interior of a motor vehicle. The protective device 1 comprises a flexible partition mesh 2, which in the stretched state according to Fig. 1 is spanned approximately vertically in a plane defined by a vehicle vertical axis and a vehicle transverse axis of the vehicle interior. The flexible partition grid 2 is at least largely rectangular in design and is bordered on its opposite sides and in the region of its upper side by an edge seam 3, which is additionally provided with an unspecified reinforcing insert at an upper edge region and at a transition to the respective lateral edge region. A lower edge region of the flexible partition grid 2 is delimited by a dimensionally stable crossbar 4, which is integrated into a seam at a lower edge region of the partition grid 2.

[0023] When mounted on the vehicle, the flexible partition mesh net 2 is spanned by a plurality of tensioning members formed by two webbing loops 5 and two suspension hooks 6 at opposite corners of an upper edge region of the flexible partition mesh net 2. The two webbing loops 5 are firmly connected to the flexible partition mesh net 2 at the opposite corners of the upper edge region of the flexible partition mesh net 2. The two webbing loops 5 are also looped through two support rings 10 of the two suspension hooks 6. When the partition mesh net 2 is in its mounted operating state, the two suspension hooks 6 protrude diagonally upwards and outwards on opposite sides and are each suspended in a roof-side bracket 7. The two roof-side brackets 7 are firmly mounted to the vehicle on opposite long sides of a roof area of ​​the vehicle interior.The partition mesh net 2 is thus suspended from the roof area of ​​the vehicle interior via the webbing loops 5 and the suspension hooks 6 on the opposite roof-side brackets 7. The approximately vertical tensioning is achieved by tensioning straps 8, shown only schematically, which are fixed to vehicle-mounted holding sections 9 in the area of ​​a loading compartment floor of the vehicle interior. Tensioning devices (not further described) enable tensioning of the tensioning straps 8, resulting in the desired stretched operating position for the partition mesh net 2. The downward tensioning of the partition mesh net 2 by means of the tensioning straps 8 and the vehicle-mounted holding sections 9 is known from the prior art.

[0024] The two hooks 6 are designed identically to each other. Fig. Figures 2 to 4 show one of the two suspension hooks 6 in detail. The above statement therefore applies equally to the opposite suspension hook.

[0025] The two roof-side brackets 7 are also designed identically to each other. Fig. Figure 5 shows one of the two roof-side brackets 7. The following applies equally to the opposite roof-side bracket 7.

[0026] Each hook 6 has a support ring 10 which is arranged in the plane of the drawing according to Fig. 2, has a triangular design. The webbing loop 5 is looped into the area of ​​a lower hypotenuse of the support ring 10. Two triangular legs, which are of different lengths in the variant shown, are connected to this hypotenuse from opposite ends of the hypotenuse. In a variant not shown, the triangular legs are of equal length. The transition from the lower leg of the support ring 10, which forms the hypotenuse, to the two triangular legs takes place via a large radius, as Fig. 2. Because the two triangular legs are of different lengths, they terminate in a suspension neck 11 offset from a merely indicated central longitudinal axis M, so that the suspension hook 6 is designed asymmetrically to the central longitudinal axis M. The suspension neck 11 extends upwards from the support ring 10 parallel to the central longitudinal axis M. The suspension neck 11 is part of a T-shaped suspension head. The suspension neck 11 carries a T-shaped web 12 at its upper end region facing away from the support ring 10.

[0027] The support ring 10, the suspension neck 11 and the T-bar 12 are in a common plane, namely a hook plane H ( Fig. 4). The T-shaped bar 12 extends transversely to the suspension neck 11 on opposite sides. The suspension neck 11 and the T-shaped bar 12 with its bar ends 12 form a suspension head in the sense of the invention.

[0028] As shown by the Fig. 4, the T-bar 12 is curved in an S-shape when viewed from above. The T-bar 12 has two bar ends 13 at its opposite end regions, which are curved outward from the hook plane H to opposite sides. One bar end 13 is in the drawing plane according to Fig. 4 is curved upwards. The opposite web end 13 is curved downwards in the plane of the drawing, with the curvatures of the two web ends 13 being executed in the same direction, resulting in the S-shape for the T-web 12. The two web ends 13 and the T-web 12 extend in a suspension plane that is aligned orthogonally to the hook plane H of the suspension hook 6.

[0029] The suspension hook 6 is manufactured as a stamped steel part, with all legs of the support ring 10 as well as the suspension neck 11 and the T-bar 12 having a square cross-section. The suspension hook 6 is designed as a single piece, with the support ring, the suspension neck 11 and the T-bar 12 being stamped out of a steel plate in a first process step. In a subsequent process step, the two bar ends 13 are curved out of the hook plane by cold forming, in particular by bending. Finally, at least in the area of ​​the support ring 10, inner edges through which the webbing loop 5 is looped are rounded, in particular by machining. Alternatively, at least the support ring 10 can be provided with a plastic coating in the area of ​​these inner edges, which likewise rounds the inner edges of the support ring 10.For both variants, it is guaranteed that, in the ready-to-use assembled state, no notch effect is exerted on the respective looped webbing loop 5.

[0030] The respective roof-side bracket 7 is also manufactured as a stamped and bent part from sheet steel as a one-piece component. The bracket 7 is attached to corresponding supporting structure components of the roof area of ​​a body supporting structure of the motor vehicle using mechanical fastening elements, in particular screw or rivet connections. The bracket 7 has a rectangular receiving opening 14 through which the T-bar 12 with its web ends 13 can be passed from below for mounting the partition mesh 2 on the roof-side brackets 7. With appropriate alignment, the T-bar 12 can alternatively also be inserted into the receiving opening 14 from one side. Adjoining one side of the receiving opening 14 is a suspension slot 15 which, starting from the receiving opening, extends openly and linearly into a holding cup 17 and opens into an end receptacle 16.The end receptacle 16 is slightly wider in a circular shape than the width of the linear suspension slot 15. The end receptacle 16 is provided coaxially in the circular holding cup 17, which is deep-drawn and bulges downward relative to a plane of the receiving mouth 14. The height of the holding cup 17 corresponds at least to the height of the T-bar 12.

[0031] To suspend the suspension hook 6 in the roof-side bracket 7, the suspension hook 6 is guided from below to the roof-side bracket 7, whereby the T-bar 12 of the suspension head is aligned with the receiving mouth 14 in order to be able to pass upwards through the receiving mouth 14.

[0032] As soon as the T-bar 12 of the suspension head has penetrated through the receiving mouth 14 so far that the suspension neck 11 of the suspension hook 6 is positioned at the height of the suspension slot 15, the suspension hook 6 can be moved sideways, whereby the suspension neck 11 enters the suspension slot 15 and is moved along the suspension slot 15. As soon as the suspension neck 11 has reached the end receptacle 16 of the suspension slot 15 in the holding pot 17, the suspended end position of the suspension hook 6 is reached. This end position is determined by means of the Fig. 5. Based on the Fig.5 also shows that, due to the circular, cylindrical design of the retaining pot 17, the suspension hook 6 can rotate within the retaining pot 17 so that the webbing loop 5, together with the suspension hook 6, can adapt to the desired orientation of the partition mesh net 2. Due to the S-shape of the T-bar 12, the suspension hook 6 cannot slide downwards out of the end receptacle 16 or the suspension slot 15. Rather, the suspension hook 6 can only be released from the roof-side bracket 7 if the suspension neck 11 with the T-bar 12 is threaded out of the suspension slot 15 in the opposite direction until the T-bar 12 has reached the receiving mouth 14 again.
