Description

Technical Field

[0001] This invention relates to a fastening device, particularly a fastening device for the rear seats of motor vehicles. Background Technology

[0002] Traditional fastening devices used to secure rear seats to the support structure of a motor vehicle are typically designed as clamps.

[0003] However, some of these fasteners offer only a small holding force.

[0004] In addition, releasable fasteners are known to provide high holding force; however, these releasable fasteners occupy a very large design space between the support members and the rear seats to be fastened. Summary of the Invention

[0005] The purpose of this invention is to provide a fastening device, particularly a fastening device for the rear seats of motor vehicles, which is simple to use and safe and reliable to operate.

[0006] The object of the present invention is particularly to provide a fastening device that requires only a small design space.

[0007] Another object of the present invention is to provide a releasable fastening device configured for repeatedly releasing and fastening a retaining section (Halteabschnitt) of a component to be fastened.

[0008] According to the present invention, a fastening device, particularly a fastening device for the rear seats of a motor vehicle, is provided. The fastening device includes a housing assembly having a fastening space for receiving a retaining section of a component to be fastened. The housing assembly is preferably insertable into a passage opening of a support member along an assembly direction. The housing assembly preferably has an abutment section at one end, particularly at the rear end opposite to the assembly direction, the abutment section having an abutment surface preferably extending transversely to the assembly direction for abutting against an edge of the support member preferably facing opposite to the assembly direction. Furthermore, a locking device is provided, having a locking element for connecting the fastening device to the support member. Additionally, the fastening device has a fastening mechanism within the fastening space, having a locking element for releasably securing the retaining section of the component to be fastened.

[0009] A particular feature of the fastening device according to the invention is that the fastening device is arranged forward toward the abutment section along the assembly direction, insertion direction, or axial direction.

[0010] In the context of this invention, the assembly direction and insertion direction should be understood as representing directions that extend substantially orthogonal to the edge region or surface of the support member through the opening. Furthermore, the assembly direction extends toward the support member.

[0011] The axial direction extends in the same direction as the assembly direction. The fastening space is preferably not the connected chamber.

[0012] According to the present invention, the abutment section is provided on one end of the fastening device, particularly on the end opposite to the assembly direction. Therefore, in the assembly direction, the fastening device first has the abutment section. Following the abutment section forward in the assembly direction are, in sequence, the fastening space, the locking device, and the fastening device. Thus, the abutment section is configured to be arranged outside the support member, and the fastening space, the locking device, and the fastening device are configured to be arranged inside the support member.

[0013] In this way, the fastening device can be arranged in the support structure, especially in the area under the rear seats in a motor vehicle, where only the abutment section protrudes from the support structure against the assembly direction. However, the latter case has a very low height.

[0014] Therefore, the fastening device for releasably securing the holding section of the component to be fastened is arranged below the support member along the assembly direction. In this way, the device according to the invention requires very little design space above the support member. Therefore, there is no need to adapt the design or structure of the rear seats to the fastening device. The rear seats can be designed and developed with complete freedom because the fastening device is arranged below the support member.

[0015] However, as mentioned above, most fastening devices for rear seats in motor vehicles require relatively large design space, especially in the area between the support member and the rear seat. Furthermore, most of these fastening devices are non-releasable. The fastening device with locking mechanism according to the invention for removably, and particularly for releasably securing retaining sections, allows the retaining section of the rear seat to be released again after fastening. In this way, the fastening device does not need to be replaced every time the rear seat needs to be released.

[0016] Furthermore, the fastening device according to the invention provides a safe and reliable fixation of the retaining section of the component to be fastened (especially the rear seat of a motor vehicle), which also enables a high retaining force.

[0017] The abutment section is preferably designed as an abutment collar with a radial perimeter. By constructing the abutment section as an abutment collar with a radial perimeter, forces applied to the fastening device in the opposite direction of assembly can be safely and reliably absorbed, as these forces are absorbed at the radial perimeter via the abutment collar and transferred to the support member.

[0018] Furthermore, an actuating element, which, according to this exemplary embodiment, is a tension belt, can be provided for releasing the locking device of the fastening device. By providing a tension belt, the holding section of the component to be fastened can be released from the fastening device in a simple and reliable manner.

[0019] The locking device may include two locking elements disposed on opposite sidewalls of the housing assembly and extending laterally outward, each having a locking edge for engaging from the rear a surface locking edge of the support member facing the assembly direction. By means of the two locking elements disposed on opposite sidewalls of the housing assembly, the fastening device can be securely and reliably fastened or fixed in the support member.

[0020] The insertion ramp and / or guide surface of the retaining section used for inserting and guiding the component to be fastened can be integrally formed within the fastening space. This facilitates the insertion of the retaining section.

[0021] According to the first embodiment, the locking device of the fastening device can be designed with a generally L-shaped cross section and preferably extends orthogonally or transversely to the assembly direction. One leg is an actuating leg, and another leg is arranged generally orthogonally to the actuating leg and is a retaining leg. The retaining leg is designed to fix the retaining section of the component to be fastened. The locking device is rotatably mounted in the housing device such that the retaining leg is preferably arranged vertically, especially parallel to the assembly direction or axial direction, in the initial position, and the actuating leg is correspondingly preferably arranged horizontally, especially orthogonally to the assembly direction or axial direction. In the fixed position where the retaining section is fixed by means of the retaining leg, the retaining leg is preferably arranged horizontally, especially orthogonally to the assembly direction or axial direction, and the actuating leg is preferably arranged vertically, especially parallel to the assembly direction or axial direction.

[0022] This fastening device is designed to securely and reliably retain the holding section of the component to be fastened in a simple manner. Simultaneously, the fastening device can also be easily released to release the holding section of the component to be fastened.

[0023] In this context, a vertical arrangement should be understood as an arrangement in which the corresponding legs are arranged approximately parallel to the sidewalls of the housing unit extending along the assembly direction. Correspondingly, in this context, a horizontal arrangement should be understood as a position in which the legs are orthogonal to the assembly direction and therefore orthogonal to the sidewalls of the housing unit.

[0024] The actuating element or traction belt may be provided with locking edges for holding and fixing the locking leg in a fixed position, wherein, in order to release the locking device, these locking edges can move against the assembly direction by means of the traction belt.

[0025] Therefore, the locking edge is designed to keep the outrigger locked in a fixed position. This locking edge extends orthogonally to the assembly direction and points along that direction. This locking edge is an integral part of the locking device.

[0026] In order to release the locking device, the locking edge moves against the assembly direction, thereby releasing the retaining section, and the retaining section can be transferred from a horizontal fixed position back to a vertical initial position against the assembly direction by the tension applied to the retaining section of the component to be fastened.

[0027] Alternatively, the locking edge can also move orthogonally to the assembly direction in order to release the locking device.

[0028] In particular, the actuating element can be connected to the locking device via the actuating structure.

[0029] The free end of the retaining leg may have a reset protrusion, thereby allowing the retaining leg to fully retract into its initial position upon leaving the retaining section. This is achieved in particular by the fact that the retaining section of the component to be fastened, through the protruding reset protrusion, completely transfers the retaining leg back to its vertical initial position. This ensures that the L-shaped locking device of the fastening mechanism is correctly positioned in its initial position.

[0030] Furthermore, the retaining surface of the retaining leg can be designed to be approximately concave. This concave design allows the retaining section of the component to be fastened, which often has a circular cross-section, to be safely and reliably accommodated and held within the retaining surface of the retaining leg.

[0031] The insertion bevel and / or guide surface of the retaining section for inserting and guiding the component to be fastened can be integrally formed within the fastening space. By providing the insertion bevel and / or guide surface, it is easy to insert the retaining section of the component to be fastened into the fastening space of the fastening device. Furthermore, damage to the retaining section is avoided. Therefore, the retaining section can be easily and reliably assembled into the fastening device.

[0032] According to a second exemplary embodiment of the invention, the fastening device may have two fastening locking elements, wherein each of the fastening locking elements has a retaining surface for retaining a retaining section for securing the component to be fastened, and wherein the fastening locking elements are preferably integrally formed on a side wall section of the housing device, wherein the side wall section is designed to be resilient transverse to the assembly direction or in the transverse direction, and wherein the fastening locking elements are preferably arranged staggered from each other in a top view.

[0033] The fastening device according to the second exemplary embodiment uses at least two resiliently designed fastening locking elements instead of an L-shaped and rotatably supported fastening device. When the retaining section of the component to be fastened is inserted into the fastening space, the retaining section is simply pressed laterally outward in the assembly direction until it passes the fastening locking elements along the assembly direction. Subsequently, the fastening locking elements securely and reliably lock behind the retaining section of the component to be fastened. This also enables the reliable securing of the retaining section of the component to be fastened by means of the fastening device according to the invention.

[0034] The traction band can be connected to the release wedge and is designed to actuate the release wedge, wherein the release wedge is capable of moving against the assembly direction in order to release the fixed position, such that the actuating surface of the release wedge, which is inclined relative to the assembly direction, enables the fastening element and preferably elastically designed sidewall to move laterally outward in the assembly direction.

[0035] By applying a corresponding tension on the traction belt, the release wedge moves against the assembly direction. The operating surface, inclined relative to the assembly direction, then contacts the elastic sidewall sections, on which the fastening element is integrally formed. These sidewall sections then move outward in the same lateral direction, thereby releasing the holding section of the component to be fastened and allowing it to be pulled out of the fastening space against the assembly direction by means of a tension force.

[0036] Once tension is no longer applied to the traction band, the elasticity of the sidewall section is strong enough to displace the release wedge along the assembly direction, causing the fastening locking element to be repositioned in its initial position.

[0037] According to this embodiment, the initial position corresponds to the fixed position. However, in the context of this invention, the initial position should be understood as indicating that the fastening section of the component to be fastened is not arranged in the fastening space and is not fixed to the fastening locking element. Correspondingly, in the fixed position, the fastening section is fixed in the fastening space by means of the fastening locking element.

[0038] The third embodiment of the invention is designed essentially according to the second exemplary embodiment. Here, the actuating element is configured as a lever device connected to a release element, wherein the release element can rotate by rotation of the lever device to release the fastening locking elements, such that the fastening locking elements can preferably slide orthogonally to the axial direction.

[0039] Furthermore, according to the present invention, a method is provided for fastening a holding section of a component to be fastened in a fastening device and releasing it from the fastening device. Attached Figure Description

[0062] The fastening device 1 according to the invention is described in more detail below with the aid of a first exemplary embodiment. Figures 1 to 6 The fastening device 1 is designed to secure the retaining section 16 of the rear seat of a motor vehicle and thus to at least partially secure the rear seat (not shown). In the context of this invention, the retaining section 16 is a section of a clamp with a preferably circular cross-section. Using the fastening device 1 according to the invention, various types of components having corresponding fastening clamps with retaining sections can, in principle, be secured. The retaining section may also have other suitable cross-sectional shapes.

[0063] The fastening device 1 has a housing device 2. The housing device 2 can be inserted into a through opening (not shown) of a support member (not shown) along the assembly direction 3 and defines a fastening space 26 extending in the axial direction.

[0064] In the context of this invention, assembly direction 3 should be understood as representing a direction that extends substantially orthogonal to the edge region or surface of the support member through the opening, defining the support member. Furthermore, assembly direction 3 also extends toward the support member.

[0065] The housing assembly 2 has a radially peripheral abutment section at its end opposite to the assembly direction 3 or at its first end, which is designed as an abutment neck ring 6. The abutment neck ring 6 has an abutment surface 7 extending orthogonally to or transverse to the assembly direction 3 or transverse to the axial direction 40, to abut against the edge of the support member facing opposite to the assembly direction 3. The abutment neck ring 6 is generally rectangular in shape when viewed from a top view.

[0066] The housing assembly 2 is generally cubic in construction, wherein locking devices 10 for connecting the fastening device 1 to the support member are provided on two opposing short front walls 8, 9. The locking devices 10 have two radially outwardly extending locking elements 11. The locking elements 11 are designed to be resilient, wherein the corresponding locking edges 12 face against the assembly direction 3.

[0067] In addition, the housing assembly 2 includes two long sidewalls 13 and 14.

[0068] A fastening device 15 is provided in the area of ​​the side wall 13 for releasably securing the retaining section 16 of the rear seat.

[0069] The fastening device 15 includes a locking device 17. The locking device 17 has a generally L-shaped cross-section and extends orthogonally or transversely to the assembly direction 3 or the axial direction 40. One leg of the locking device constitutes an actuating leg 18, and the other leg constitutes a retaining leg 19. The retaining leg 19 is arranged generally orthogonally to the actuating leg 18 and is designed to secure the retaining section 16 of the component to be fastened.

[0070] The locking device 17 is rotatably supported in the side wall 13 or the front wall 8, 9. For rotatable support, the locking device has circular support sections 20, 21 at both ends. The support sections 20, 21 are rotatably supported in the side wall 13 via corresponding inlet openings 24, 25 in corresponding support receptacles 22, 23. The inlet openings are accordingly designed to surround the support sections in a locking manner.

[0071] In the initial position, the outrigger 19 is preferably arranged vertically parallel to the assembly direction 3 or the axial direction 40, and the actuating outrigger 18 is correspondingly preferably arranged horizontally orthogonally to the assembly direction 3 or the axial direction 40.

[0072] In the fixed position 31 where the retaining section 16 of the component to be fastened is fixed by means of the retaining leg 19, the retaining leg 19 is arranged horizontally parallel to the assembly direction 3 or the axial direction, and the actuating leg 18 is arranged vertically orthogonally to the assembly direction 3.

[0073] In the initial position 32, the outrigger 19 is preferably arranged vertically orthogonal to the assembly direction 3 or the axial direction 40, and the actuating outrigger 18 is preferably arranged horizontally parallel to the assembly direction 3 or the axial direction 40.

[0074] In the contact area between the retaining leg 19 and the retaining section 16 of the component to be fastened, a retaining surface 34 with a generally concave structure is provided on the retaining leg 19.

[0075] The free end of the retaining leg 19 has a reset protrusion 41 with a generally arcuate cross-section and extends into a fastening space 26 defined by sidewalls 13, 14 and endwalls 8, 9. The reset protrusion 41 is designed to cause the retaining section 16 to contact the reset protrusion upon departure, thereby causing the locking device 17 to return to the initial position 32.

[0076] The support leg 19 is provided with stop surfaces on both sides or generally along and against the assembly direction 3.

[0077] In order to restrict the rotational movement of the locking device 17 when moving from the initial position 32 to the fixed position 31, a fixed stop surface 42 is formed on the retaining leg 19, which is oriented generally against the assembly direction 3.

[0078] A corresponding fixed stop surface 43, designed to correspond to the fixed stop surface, is provided in the area of ​​the side wall 13.

[0079] In order to restrict the rotational movement of the locking device 17 when moving from the fixed position 31 to the initial position 32, an exit stop surface 44 is formed on the retaining leg 19, which is generally oriented along the assembly direction 3.

[0080] A corresponding exit stop surface 45, designed to correspond to the exit stop surface 44, is provided in the area of ​​the side wall 13.

[0081] Insertion ramps 27 are arranged in the fastening space 26, and these insertion ramps taper gradually along the assembly direction 3. In this exemplary embodiment, the insertion ramps 27 are provided on the front walls 8, 9, but may also be additionally and / or alternatively arranged on the side walls 13, 14.

[0082] The surfaces of the sidewalls 13 and 14 facing the fastening space 26 form guide surfaces 28. Guide surfaces 28 may also be additionally and / or alternatively provided on the front walls 8 and 9.

[0083] The insertion of the inclined surface 27 and the guide surface 28 facilitates the insertion of the holding section 16 of the component to be fastened.

[0084] Furthermore, an actuating element 29, particularly a tension belt 29, is provided for releasing the locking device 17 of the fastening device 15. The tension belt 29 has a release element 37, particularly a locking edge 30, in the region of the locking device 17 for holding and securing the retaining leg 19 in the fixed position 31. To release the locking device 17, the tension belt 29 is subjected to a tension force preferably orthogonal to the assembly direction, causing the locking edge 30 to move against the assembly direction 3 and release the retaining leg 19, thereby allowing the device 1 to be moved to the initial position 32.

[0085] Alternatively, in order to release the locking device 17, the locking edge 30 can be subjected to tension, causing the locking edge 30 to move orthogonally to the assembly direction 3 and release the retaining leg 19, thereby allowing the device 1 to be moved to the initial position 32.

[0086] Furthermore, a disassembly recess 46 is constructed in the area of ​​the locking element within the abutment section. This disassembly recess 46 allows the locking element 11 to be actuated or released, thereby enabling the fastening device to be released or disassembled from the passage opening of the support member.

[0087] The following is a brief description of a method for actuating the fastening device 1 according to the present invention. The method includes the following steps: - Insert the retaining section 16 into the fastening space 26 of the fastening device 1 along the assembly direction 3; - Keep section 16 in contact with actuating leg 18 and move the locking device to fixed position 31; - The retaining leg 19 will engage from the rear to the locking edge 30 of the actuator element 29.

[0088] To release section 16 from the fastening device, a method is proposed, comprising the following steps: - Move the retaining section 16 against the assembly direction 3 and pull it on the traction belt 29 at the same time, so that the locking edge 30 moves along the assembly direction and releases the retaining leg 19; - Release the retaining section 16 from the fastening space 26 and move the locking device 17 from the fixed position 31 to the initial position 32.

[0089] The fastening device 1 according to the present invention will now be described in more detail with the aid of a second exemplary embodiment. Figures 7 to 16 Unless otherwise stated, the second exemplary embodiment has the same technical features as the first exemplary embodiment. Identical components are denoted by the same reference numerals.

[0090] According to a second exemplary embodiment, the fastening device 1 has two fastening locking elements 33. Each fastening locking element 33 has a retaining surface 34 for securing a retaining section 16 of the component to be fastened. The retaining surface 34 faces generally along the assembly direction 3.

[0091] The fastening locking element 33 is fastened to the elastic sidewall sections 35 and 36 of the sidewalls 13 and 14. The sidewall sections 35 and 36 are designed to be elastic, particularly transverse to the assembly direction 3. In the top view, the fastening locking elements 33 are staggered or alternately arranged, meaning that the fastening locking elements 33 are integrally formed on the sidewall section 35 and the opposite sidewall section 36.

[0092] Alternatively, the sidewall sections 35, 36 or the sidewall itself may be rigidly designed, wherein only the fastening locking element 33 is designed to be orthogonal to or transverse to the assembly direction 3.

[0093] According to this exemplary embodiment, an actuating element, in particular a traction band 29, is also provided, wherein the traction band 29 is connected to a release element, in particular a release wedge 37. The traction band 29 is accordingly designed to actuate the release wedge 37.

[0094] To release the fixed position, the release wedge 37 can be moved against the assembly direction 3 by means of the traction belt 29. The release wedge has two actuating surfaces 38 and 39 that are inclined relative to the assembly direction.

[0095] As the release wedge 37 moves against the assembly direction 3, the free ends of the sidewall sections 35 and 36, which are located at the front along the assembly direction, slide along the actuating surfaces 38 and 39 and thereby move laterally outward. In this way, the fastening locking element 33, which is connected to the sidewall sections 35 and 36, releases the holding section 16 of the component to be fastened, so that the component can be pulled out from the fastening space 26 against the assembly direction 3.

[0096] The corresponding method according to the second exemplary embodiment is briefly described below. The method includes the following steps: - Insert the retaining section 16 of the component to be fastened into the fastening space 26 along the assembly direction. - The retaining section 16 will contact the surface of the actuating locking element 33 facing along the assembly direction, thereby causing the actuating locking element 33 and the associated sidewall sections 35, 36 to bend outward. - The retaining surface 34 of the fastening locking element is engaged from the rear onto the surface of the retaining section 16 facing in the opposite assembly direction.

[0097] In this way, section 16 will be securely and reliably fixed in fastening device 1.

[0098] The corresponding method for releasing or transferring from the fixed position 31 to the initial position 32 includes the following steps: - Apply tension to the actuating element or traction band 29, thereby causing the release wedge 37 to move against the assembly direction 3. - By using the release wedge to push the fastening locking element 33 open or push it laterally outward, the retaining surface 34 is released from the retaining device 16. - Make the holding section 16 move against the assembly direction. Move to the initial position 32.

[0099] According to the third exemplary embodiment, the fastening device 1 according to the present invention substantially corresponds to the fastening device according to the second exemplary embodiment of the present invention. Figures 15 to 21 Unless otherwise stated, the fastening device has the same technical features as the fastening device 1 according to the second embodiment.

[0100] Therefore, the fastening device also includes two fastening locking elements 33, each having a retaining surface 34 for securing the retaining section 16 of the component to be fastened. The retaining surface 34 is oriented generally along the assembly direction 3 and is concave in order to abut against the cross-section of the retaining section 16.

[0101] The fastening locking element 33 is also fastened to the elastic side wall sections 35 and 36 of the side walls 13 and 14.

[0102] According to this exemplary embodiment, the actuating element is designed as a rod, wherein the actuating element 29 includes a lever device, which includes a lever section 47, a shaft section 48, and a release element 37 (especially an expansion element 49).

[0103] The lever section 47 extends approximately orthogonally to the assembly direction 3 or the axial direction 4 and is rotatably supported in the housing device 2 along a longitudinal axis extending in the axial direction 40 around the shaft section 48.

[0104] An expansion element 49 is formed on the shaft section 48 at the front end along the assembly direction 3.

[0105] According to this exemplary embodiment, the elastic sidewall sections 35 and 36 are lengthened along the axial direction 40 by manipulating the sections 50 and 51.

[0106] Therefore, the operating sections 50 and 51 are arranged on the front end of the fastening device 1 along the assembly direction 3. An expansion element 49 is accommodated in the area between the actuating elements 50 and 51, such that by rotating the shaft section 48, preferably by means of the lever section 47, preferably by 90°, the fastening locking element or the corresponding side wall sections 35 and 36 are preferably generally orthogonal to the assembly direction 3 or pushed outward, so that the corresponding retaining surface 34 of the fastening locking element 33 releases the retaining section 16.

[0107] The corresponding method according to a third exemplary embodiment of the fastening device 1 is briefly described below. The method includes the following steps: - Insert the retaining section 16 of the component to be fastened into the fastening space 26 along the assembly direction 3. - Make the fastening section 16 contact the side wall sections 35 and 36, thereby pushing the fastening locking element 33 outward. - The retaining surface 34 of the fastening locking element is engaged from the rear onto the surface of the retaining section 16 facing in the opposite assembly direction.

[0108] - Move to fixed position 31.

[0109] This method secures device 16 in the fastening device safely and reliably.

[0110] The corresponding method for releasing or transferring from the fixed position 31 to the initial position 32 includes the following steps: - The lever section 47 of the actuating element is rotated, preferably by 90°, about the longitudinal axis of the shaft section 48, thereby causing the actuating sections 50 and 51 to bend away from each other by means of the expansion element 49, thereby causing the retaining surface 34 to release the retaining section 16. - Make the holding section 16 move against the assembly direction. - Move to initial position 32.

[0111] As long as it is technically meaningful, the technical features illustrated above with the aid of the three exemplary embodiments can be combined with each other as needed.
