Description
[0001] The invention relates to a dirt protection device for a vehicle seat or a rear seat system and a method for the convenient attachment of the dirt protection device.
[0002] To protect against soiling, it is known to fit motor vehicle seats with protective covers designed as seat covers. These are subsequently attached to the backrest for an extended period, so that the new visible surface of the covered backrest is formed by the surface of the seat cover.
[0003] A motor vehicle seat described in DE 100 49 667 A1 comprises a seat section and an attached backrest, which has a front contact surface for the seat user and a rear viewing surface with a protective cover for the viewing surface. In its unfolded state, the protective cover is stowed and attached to a bracket of the motor vehicle seat. In its unfolded state, the protective cover covers the viewing surface and is positioned with its end opposite the bracket against the end of the backrest opposite the bracket.
[0004] A protective cover arrangement is known from DE 199 31 020 A1. There, a protective cover is described in particular as a blanket or tarpaulin that can be placed, for example, in a vehicle between the backrest of a rear bench seat and the backrest of a front seat.
[0005] DE 10 2006 048 302 A1 discloses a protective cover arrangement for the interior of a vehicle with retaining elements that can be attached to interior fittings of the vehicle. For such a protective cover arrangement, a roller box with at least one winding shaft is proposed, on which the protective cover is attached for two-layer winding or unwinding.
[0006] DE 10 2008 030 761 A1 relates to a protective device for a vehicle seat with a protective element by means of which at least a surface area of the vehicle seat facing a seat occupant can be covered, wherein the protective device can be arranged on the vehicle seat via a stowage device, wherein the stowage element can be arranged in a stowage position by means of the stowage device, and wherein a holding device is further provided by means of which the protective element can be arranged in a covering position on the vehicle seat.
[0007] A comfort seat known from DE 100 49 667 A1 allows for the arrangement of a protective cover on the back of the comfort seat.
[0008] With the other known solutions, in particular DE 10 2006 048 302 A1 and DE 199 31 020 A1, the problem is that the operation for arranging the protective device is relatively cumbersome.
[0009] The protective device described in DE 10 2008 030 761 A1 allows for the covering of the seat cushion or backrest of a vehicle seat or rear bench seat, either separately or together, whereby a deflection device is to be arranged in the corner area between the seat cushion and backrest. Details of the deflection device are not described. This is because, for reasons of space and comfort, it is difficult to arrange a deflection device in the corner area between the seat cushion and backrest.
[0010] Based on this state of the art, a simple solution is sought that enables complete coverage of a seat section and backrest of a vehicle seat or a rear seat section or backrest of a rear bench seat, in which a tangible, physical covering of the seat section and backrest or rear seat section and backrest is achieved, changing the visual appearance and protecting the seat sections and backrest, and which is easy to handle and comfortable to operate.
[0011] The object of the present invention is therefore to provide a protective device for a vehicle seat or a rear seat system of the type mentioned above, which enables a particularly user-friendly and thus comfortable covering of the surface area of the vehicle seat or rear seat system facing the seat occupant, and by means of which a tight covering of the surface of the vehicle seat or rear seat system is also achieved.
[0012] The invention relates to a dirt protection device, as described in DE 10 2008 030 761 A1, for a vehicle seat with a seat section and a backrest or a rear seat assembly with a rear seat section and a rear seat backrest, by means of which a surface area facing an occupant can be temporarily covered, wherein the vehicle seat or the rear seat assembly has an integrated storage device which houses the protective element of the dirt protection device in a storage position from which the protective element can be reversibly brought into a covering position.
[0013] The problem is solved in conjunction with these features of the preamble of claim 1 by the fact that the protective element of the contamination protection has provisions by which the protective element can be attached in one piece along the surface of the seat part and the backrest of the vehicle seat or the rear seat assembly to means provided for this purpose and can be tensioned at least largely without creases.
[0014] The invention provides for two embodiments.
[0015] In one initial design variant, the storage device is located in the lower or front area of the seat section.
[0016] In this first design variant, the provisions are arranged in the protective element essentially at the free end and essentially in the middle of the protective element in order to attach the protective element, starting from the lower or front area of the seat part, in the upper or rear area of the backrest and in the corner area between the seat part and the backrest of the vehicle seat or the rear seat system, and to tension it at least largely without creases.
[0017] In a first alternative, it is provided that the provisions are openings located at the free end and essentially in the middle of the protective element, which correspond to the outer contour of at least one headrest arranged at the end of the backrest and a vehicle seat-side fastening element arranged centrally in the corner area, whereby the protective element can be attached in one piece along the surface of the seat part and the backrest of the vehicle seat or rear seat system, starting from the lower or front area of the seat part, in the upper or rear area of the backrest and in the corner area, and can be tensioned at least largely without creases.
[0018] In a second alternative to the first design variant, the free end of the protective element has no openings, but rather hooks attached to it with rubber bands or similar devices. The protective element is secured by hooking these hooks onto the headrest posts of the headrests located on the upper front of the seat back. The rubber bands are elastic elements that have the advantage of accommodating or compensating for the movements of the protective element when an occupant sits down, so that the protective element automatically returns to its taut position after the occupant leaves the seat.
[0019] This results in the following procedure for attaching a dirt protection to a vehicle seat with a seat section and a backrest or a rear seat system with a rear seat section and a rear seat backrest in this first design variant: First, in a first tensioning step, the protective element is led out from a storage device located in the front or lower area of the seat section to the upper area of the backrest, after which the protective element is attached in the upper area of the backrest in a second tensioning step, after which the protective element is finally attached in a third tensioning step in the corner area between the seat section and the backrest in one piece along the surface of the seat section and the backrest and tensioned at least largely without wrinkles.
[0020] In a second design variant, the storage device is located in the rear or upper area of the backrest.
[0021] In this second design variant, the provisions are arranged in the protective element essentially at the free end and essentially in the middle of the protective element as well as at the non-free end in order to attach the protective element, starting from the rear or upper area of the backrest, in the front or lower area of the seat part and in the corner area between the seat part and the backrest of the vehicle seat or the rear seat system, and to tension it at least largely without creases.
[0022] In a first alternative of the second embodiment, it is provided that the provisions at the free end are fastening elements and the provisions located substantially in the middle of the protective element and at the non-free end are openings, wherein the fastening elements at the front or lower end of the seat part provide for fastening the protective element and the openings at the non-free end correspond to the outer contour of at least one headrest arranged on the backrest and the openings located centrally in the corner area correspond to a vehicle seat-side fastening element, whereby the protective element, starting from the upper or rear area of the backrest, in the front or lower area of the seat part and in the corner area, can be attached in one piece along the surface of the backrest and the seat part as well as to the headrests of the vehicle seat or the rear seat system and can be tensioned at least largely without creases.
[0023] In a second alternative of the second embodiment, the free end of the protective element has no openings, but rather hooks that are attached to the free end of the protective element with rubber bands or similar devices. The attachment is achieved by hooking the hooks onto the underside or front of the seat component, preferably onto the seat pan of the seat component. The rubber bands are elastic elements that have the advantage of accommodating or compensating for the movements of the protective element caused when an occupant sits down, so that the protective element automatically returns to its taut position after the occupant leaves the seat.
[0024] This results in the following procedure for attaching a dirt protection to a vehicle seat with a seat section and a backrest or a rear seat system with a rear seat section and a rear seat backrest in this second design variant: First, in a first tensioning step, the protective element is led out from a storage device located in the rear or upper area of the backrest to the front or lower area of the seat section, after which the protective element is attached in a second tensioning step in the front or lower area of the seat section, after which the protective element is finally attached in a third tensioning step in the corner area between the seat section and the backrest in one piece along the surface of the seat section and the backrest and tensioned at least largely without wrinkles.

At the right end of the cage 30A Viewed in the direction of travel (shown on the left in each figure), this is formed by a first lid-like hollow cylinder. 30J-1 closed end 30E the winding shaft 30D , which has an axial cylindrical pin 30H features, over the pen 30Hof the hollow cylinder 30J-1 at the right end of the cage 30A The pen is rotatably mounted. 30H is for the storage of the winding shaft 30D firstly, in the cage 30A plugged in and secondly for storing the cage 30A in axial extension of the winding shaft 30D into a circular hole in the seat tub, designed as a receiving element (not shown). 12 , 12A (not shown) inserted in a form-fitting manner.
[0080] In the open ending 30F the winding shaft 30D The long sleeve is inserted into the hollow shaft (shown in the figures on the right). 30I , which, viewed in the direction of travel, are at the left end of the cage 30A (in the figures on the right) in a circular opening 30L of the cage 30A is stored. This opening 30LIt also serves as an assembly opening for the worker to insert all components of the wave-like construction into the cage. 30A and for removing and installing the winding shafts 30D and the protective element wound onto it 102B For cleaning purposes. A closed end of the long sleeve. 30I is as a transverse wing 30M (best seen in Fig. 4E) designed, which is equipped with the long sleeve 30I a T-piece forms and leads into a shallow chamber 30N is pushed, which is part of the seat tub 12 , 12A (in Fig. 4A indicated) is attached at the front left (shown on the right in the figures).
[0081] The winding shaft 30D and the cage 30A , in whose opening 30L ( Fig. 4E) the long sleeve 30I The seat is opposite the seat tub. 12 , 12A indirectly through a handle that engages the T-piece in a form-fitting manner 30Osecured, which is in the chamber 30N the sitz bath 12 , 12A The handle is mounted on a rotating bearing. 30O is through a first spring element 30P force-fit, the T-shaped transverse wing 30M in the axial direction of the winding shaft 30D seen as form-fittingly enclosing the front face, against the transverse wing 30M Pressed. Through the T-piece and the handle. 30O is the long sleeve 30I After assembly, the cage is impervious to rotation. 30A fastened and secured.
[0082] During the assembly of the winding shaft 30D in the cage 30A will the winding shaft 30D and the long sleeve 30I about the pen 30H in the cage 30A and later after the cage was installed 30A in the sitz bath 12 , 12A (in the figures, on the left side of the cage) 30A ) rotatably mounted by insertion. The long sleeve 30Iwas previously wound into the winding shaft 30D inserted.
[0083] On this long sleeve 30I sits, like Fig. 4F points to the closed end 30E directed a second spring element, in particular a coil spring 30Q , which are located at their opposite end in a first inner sleeve 30G-1 It sits and is attached there. This inner sleeve 30G-1 As all the figures show, it lies in a starting position in which the winding shaft 30D wound-up protective element 102B is not unwound, axially on the first freely movable hollow cylinder 30J-1 and is opposite the non-rotatable long sleeve 30I in the winding shaft 30D Rotatable and axially displaceable mounting.
[0084] Finally, the long sleeve 30I , as described in the previous paragraph, non-rotatable in the cage 30A fastened and secured. The winding shaft 30DHowever, it remains in comparison to the long sleeve 30I rotatable and is located in the area of the long sleeve 30I from the long sleeve 30I guided.
[0085] Inside the winding shaft 30 lie outside the area of the long sleeve 30I the longitudinal rails 30B-1 , which are opposite the coil spring 30Q , which are hereinafter referred to as coil spring element, are arranged externally.
[0086] Fig. 4B and Fig. Figure 4C shows an enlarged view of the main components of the stowage system. 30 without the seat structure, whereby Fig. 4C in particular the longitudinal rails 30B-1 the winding shaft, which is only shown there transparently as a cut edge 30D and the long sleeve 30I and the coil spring element 30Q shows which is within the longitudinal rails 30B-1 This is why the longitudinal rails 30B-1 as external longitudinal rails 30B-1This arrangement of the coil spring element is called... 30Q in the outer longitudinal rails 30B-1 This is a significant difference between the first embodiment and the second embodiment, which will be explained later.
[0087] On the inside of the winding shaft 30D running from the closed end 30E out (into the Fig. 4A to Fig. 4E (shown on the left) the longitudinal rails 30B-1 , which provide axial guidance for the first inner sleeve 30G-1 serve. The longitudinal rails 30B-1 encompass the first inner sleeve 30G-1 , on the first hollow cylinder 30J-1 , which serves as a lid-like end element of the wave-like structure on this side. The first inner sleeve 30G-1 has grooves on its outer surface (not shown in detail) into which the longitudinal rails 30B-1 intervene like a spring.
[0088] The described arrangement results in the following function. When the winding shaft 30D when removing the protective element 102B When turning, the inner longitudinal rails take over 30B-1 the first inner sleeve 30G-1 via the spring-like engagement of the longitudinal rails 30B-1 into the grooves of the first inner sleeve 30G-1 Involuntarily included. The first rotatable inner sleeve 30G-1 and the fixed, non-rotating long sleeve 30I are via the coil spring element 30Q interconnected. Fig. 4C shows that the coil spring element 30Q on the one hand in the first inner sleeve 30G-1 It is fixed. On the opposite side is the coil spring element. 30Q , How Fig. 4F shows, on the other hand, the long sleeve 30I via a holding element 30V fixed. The coil spring element 30Q and the first inner sleeve 30G-1can be achieved via an internal rod-shaped guide element, which on one side is inserted into the first inner sleeve 30G-1 is inserted and, on the other hand, is centrally located in the central axis of the long sleeve 30I is specified, to be carried out. Such an element is in Fig. 4D with the reference symbol 30W depicted.
[0089] By rotating the winding shaft 30D The coil spring element 30Q in the axial direction within the winding shaft 30D It is tensioned and builds up a restoring torque. This causes the first inner sleeve to... 30G-1 via the spring-like engagement of the longitudinal rails 30B-1 into the grooves of the first inner sleeve 30G-1 towards the long sleeve 30I shifted (not shown). The further the protective element 102B pulled out, that is, the further the winding shaft 30D The more it is turned, the further the first inner sleeve moves. 30G-1 towards the long sleeve 30Iand the stronger the restoring torque becomes, as the coil spring element 30Q the tension increases. Will the protective element become more and more intense? 102B Once released, the winding shaft 30D the protective element was turned back by the restoring torque and the protective element 102B The rudder automatically returns to its starting position by utilizing the moment and simultaneously resetting the components that are changing in position. 30S withdrawn. Second embodiment (Fig. 5A to Fig. 5D):
[0090] The wave-like structure of the second embodiment is also housed in an identical cage. 30A It is arranged and similarly structured, but differs in some details.
[0091] The wave-like construction of the second embodiment also has a closed end. 30E and an open ending 30F up. The one at the right end of the cage. 30Aarranged second lid-like hollow cylinders 30J-2 differs from the first hollow cylinder 30J-1 of the first embodiment in that noses are provided on its cylindrical outer surface 30J-21 are arranged with internal grooves of the winding shaft, which are not shown in detail. 30D by pushing up the winding shaft 30D on the first hollow cylinder 30J-1 are able to be brought into positive engagement in the axial direction.
[0092] The second difference between the first embodiment and the second embodiment is that the winding shaft 30D no longitudinal rails inside 30B-1 exhibits.
[0093] In the second embodiment, longitudinal rails 30B-2 trained, who like Fig. 5A shows the closed end 30E forming, with the second hollow cylinder 30J-2 are connected. The second hollow cylinder 30J-2 and the longitudinal rails 30B-2are preferably several components which are subsequently joined to form one component, having previously inserted a second inner sleeve 30G-2 , which will be discussed later, the longitudinal rails 30B-2 is being pushed.
[0094] How Fig. 5B shows where the longitudinal rails are located. 30B-2 in the second embodiment within the coil spring element 30Q and are therefore referred to as internal longitudinal rails.
[0095] As the Fig. 5A to Fig. 5D further shows consistently that it is in axial extension of the inner longitudinal rails 30B-2 a cylindrical extension piece was formed.
[0096] These changes will affect the second inner sleeve 30G-2 the second embodiment compared to the first inner sleeve 30G-2 The first embodiment was modified.
[0097] The second inner sleeve 30G-2It now has no grooves for receiving the outer longitudinal rails. 30B-1 In the second embodiment, a star-shaped opening is provided within the second inner sleeve. 30G-2 executed, via which the second inner sleeve 30G-2 on the inner longitudinal rails 30B-2 is mounted in a movable position.
[0098] During the assembly of the wave-like structure in the cage 30A The second inner sleeve will be inserted first. 30G-2 on the inner longitudinal rails 30B-2 pushed up and the longitudinal rails 30B-2 are combined with the second hollow cylinder 30J-2 connected. The second hollow cylinder 30J-2 The cage is located at the right end of the cage, just as in the first embodiment. 30A one inserted and also in the circular hole provided for this purpose in the seat tub 12 , 12A Inserted and stored in a form-fitting manner.
[0099] The opening is arranged analogously to the first embodiment 30L at the open end 30F of the cage 30A (shown on the right) is how Fig. 5C shows the long sleeve 30I on the cylindrical extension piece of the inner longitudinal rails 30B-2 pushed along the longitudinal rails 30B-2 facing end of the long sleeve 30I As in the first embodiment, it is a holding element. 30V arranged in which the coil spring element 30Q is fixed.
[0100] On the opposite side is the coil spring element. 30Q analogous to the first embodiment, in the second embodiment in relation to the long sleeve 30I rotatable inner sleeve 30G-2 fixed. The retaining element 30V It also serves as a spacer between the cylindrical extension piece of the inner longitudinal rails. 30B-2 and the long sleeve 30IFinally, the winding shaft, designed as a hollow shaft, is 30D through the opening 30I pushed until the end facing the front was on the second hollow cylinder 30J-2 hits, whereby internal grooves with the noses 30J-2 of the second hollow cylinder 30J-2 form a positive-locking connection. The components 30J-2 , 30G-2 , 30B-2 , 30Q , 30I , 30D The wave-like construction can also be pre-assembled and inserted together in one operation. The winding shaft 30D is, as again the cutting edge of the Fig. 5D shows, on the second hollow cylinder 30J-2 and the long sleeve 30I Rotatably mounted. None of the Fig. 5A to Fig. 5D shows the winding shaft 30D with its cylindrical outer surface, since the winding shaft 30DThe components belonging to the wave-like construction and to be described are concealed; rather, the winding shaft is 30D not at all or in Fig. 5D transparent and shown only with its cut edge.
[0101] The described arrangement results in the following function. When the winding shaft 30D when removing the protective element 102B When it turns, it takes over the second hollow cylinder 30J-2 the inner longitudinal rails 30B-2 and thus those on the inner longitudinal rails 30B-2 arranged second inner sleeve 30G-2 forced to go.
[0102] Because the coil spring element 30Q on the one hand, on the second inner sleeve 30G-2 and on the other hand, on the non-rotatable long sleeve 30I is fixed and the inner longitudinal rails 30B-2 together with the second inner sleeve 30J-2 opposite the long sleeve 30Irotating the coil spring element 30Q It is tensioned in the axial direction and thereby builds up a restoring torque. This causes the second inner sleeve to... 30G-2 on the inner longitudinal rails 30B-2 towards the long sleeve 30I shifted (not shown). Again, the further the protective element is moved, the more likely it is that the better. 102B is pulled out and the winding shaft 30D The further the rotation, the further the second inner sleeve moves. 30G-2 towards the long sleeve 30I and the stronger the restoring torque becomes, as the coil spring element 30Q The tension increases. By releasing the protective element. 102B will the winding shaft 30D The restoring torque rotates the components back into their initial position and the protective element is retracted into the rudder. 30S withdrawn. Both forms of execution:
[0103] In both embodiments, there are two lateral, lower ends. 30U of the cage 30A from the installation space of the storage device 30 protrude. The lower ends 30U are each with a hole 30R ( Fig. 4D). The transverse rudder is fitted into these two openings. 30S with a guide slot 30T stored. From this guide slot 30T the free end of the coiled protective element protrudes 102B (not shown) out, with a transverse bar (not shown) along the reference end on the rudder 30S it fits snugly and prevents the end from slipping in.
[0104] The crossbar also serves as a handle for pulling out the cover, which is particularly advantageous when using it with one hand. The cover is locked in the extended position by the devices already described on the rear seat assembly. 20After unlocking, the cover is secured by the force exerted when the protective element is unrolled. 102B built-up restoring torque of the coil spring element 30Q automatically wound up, and the guide slot 30T It also serves as a dirt wiper, as the outside of the cover slides over a flat sliding element in the guide slot. 30T is pulled, which retains any adhering dirt particles.
