Description

Detailed Description of the Invention

[0001] The present invention relates to a anchoring system for anchoring a child car seat and / or a base for a child car seat to a vehicle seat.

[0002] A child car seat is understood by those skilled in the art to be a child restraint system for transporting a child in a vehicle, preferably an automobile.

[0003] It should be noted that in the context of the present invention, the term "child seat" should be understood as a generic term for (typical) child seats, infant carriers, booster seats, booster cushions, etc. For example, a child seat according to the present invention may be a typical child seat (for larger children, e.g., a group I / II and / or III child seat) that is structurally separated from the seating area and has a backrest that can be tilted relative to the seating area as required. The structural boundary between the two can be formed, for example, by a bend or the like. In general, however, (unless stated otherwise in the specific context) a child seat should always be understood as a shortened form of "child seat, e.g., infant carrier, booster seat and / or booster cushion," or in the context of the present invention, features provided for (typical) child seats are in principle also applicable, for example, to infant carriers, booster seats and / or booster cushions (unless stated otherwise), and vice versa. The same applies to the term "child", which should also be understood as a generic term for children, infants and toddlers. So-called "infant carriers" often comprise a single-piece shell for holding an infant or child, and may include a separate belt system, possibly a headrest, and possibly other components. Such "infant carriers" do not have a (structurally separate) backrest, but rather a rear portion that joins to a "seat area" that can accommodate the child's buttocks.

[0004] The term "child seat base" is understood by those skilled in the art to mean in particular a base to which a child seat can be removably or irremovably fastened.

[0005] Child seats, infant carriers, booster seats, etc. that can be tethered to vehicle seats have been known for some time. Such child seats, infant carriers, booster seats, etc. provide a seating position for children, infants, and small children, offering them a high level of protection, particularly in the event of an accident and / or emergency braking. Such child seats can be secured using the vehicle's belt system or by an Isofix fastening system. This fastening system secures the child seat to the vehicle seat in the event of an accident, thereby keeping it in place on the vehicle seat and preventing it from being thrown forward, particularly in the event of a rear-end collision and / or emergency braking.

[0006] Because such child seats are often swapped between different vehicles, particularly motor vehicles, and / or installed and removed, it is particularly important that the child seats be removably tethered to facilitate ease of handling, although ease of handling should not come at the expense of the safety of the child on the road or in the event of an accident.

[0007] Therefore, the attachment of the child car seat to the vehicle seat must be as stable as possible, but at the same time, it is desirable that the attachment allow a certain degree of adjustability in order to best fit the various car seats.

[0008] An adjustable anchoring system, in particular a telescoping system, for anchoring a child restraint system, in particular a child car seat, to a vehicle seat is known, for example from EP 3600954 B1. However, although the anchoring system disclosed in this document consists of a large number of different individual parts (with the result that this design is considered to require improvement in terms of manufacturing costs and susceptibility to malfunction in use), it lacks means for detecting the anchoring status of the child restraint system.

[0009] EP1871637A1 discloses a child restraint system, in particular a fastening system for fastening a child car seat to a vehicle seat. The fastening system comprises a first connector for connecting to the vehicle seat and a second connector for connecting to an anchor of the child car seat, the second connector comprising a detector for detecting a secure connection to the vehicle seat. However, it is believed that the reliability of the detection according to EP1871637A1 needs improvement. Another disadvantage of this fastening system is that it is not very user-friendly to adjust the length of the system using a pin.

[0010] The object of the present invention is therefore to propose a fastening system for fastening a child car seat and / or a base for a child car seat to a vehicle seat, which meets the above-mentioned requirements in terms of stability, ease of use, safety and versatility as cost-effectively and as few defects as possible.

[0011] This problem is solved in particular by the features of claim 1.

[0012] In particular, the problem is a fastening system for fastening a child car seat and / or a base for a child car seat to a vehicle seat, comprising: - a hook suitable for engaging around a bracket on the vehicle side, in particular an Isofix anchor (or an anchor according to ISO standard 13216 or United Nations Economic Commission for Europe standard R145), for connecting the anchoring system to the vehicle seat, the hook being switchable between a first position in which the anchoring system is not connected to the vehicle seat (when the anchoring system is in use) and a second position in which the anchoring system is connected to the vehicle seat (when the anchoring system is in use); - a detection device, preferably of an electrical type, in particular comprising a sensor suitable for detecting whether the hook is in the first or second position (and thus whether the child seat or the base for the child seat is in use or not), the detection device being configured to indirectly detect each position and / or the detection device, in particular the sensor, being spaced apart from the hook both when the hook is in the first position and when it is in the second position; The problem is solved by a fastening system comprising:

[0013] The core idea of ​​the present invention is that the respective positions are detected indirectly, rather than directly. Therefore, the positions can be detected in a particularly reliable and structurally simple manner. In particular, the path for transmitting information about the state determined by the detection device (e.g., toward the evaluation unit and / or the display unit and / or the notification device) is shortened in principle. In contrast to the prior art, for example, no (electrical) cables or only short cables are required to transmit detected information about the state of use of the child car seat or the child car seat base along the (longitudinally displaceable) anchoring system. This also results in the further advantage that the anchoring system according to the present invention has a longer service life, for example, since there are no additional or only relatively short (electrical) cables that can be broken, worn, etc. during the service life of the anchoring system. Another advantage of the anchoring system according to the present invention can be that the absence or shortening of cables allows for improved or simplified longitudinal displacement compared to prior art embodiments. In this connection, it is also recognized that in the prior art, as for example in EP 1 871 637 A1, the detector is arranged directly on the surface of the "second connector" (as it is called in EP 1 871 637 A1), which in particular results in the problem that the cable transmitting the detector information from the second connector to a display device or display unit spatially separated from the second connector can be damaged, for example crushed, broken and / or worn.

[0014] Unless expressly stated otherwise, terms such as "first," "second," and the like, e.g., a second spring, are used to distinguish between different elements. Thus, referring to a first spring or a second spring does not imply that there must necessarily be more than one spring.

[0015] Preferably, the anchoring system comprises a mobile device (preferably mechanical and / or rigid and / or with a maximum overall length—understood as the distance between a pair of points of the mobile device that are maximally distant from each other—of at least 1 cm or at least 3 cm or at least 5 cm or at least 10 cm), in particular movable relative to the hook and having at least two mobile device positions depending on the position of the hook, in particular a first mobile device position or a second mobile device position that is in contact with the hook in at least one or exactly one position, and which can assume at least two mobile device positions depending on the position of the hook, in particular the first mobile device position, the second mobile device position and / or the third mobile device position, and the detection device is configured in particular to detect each mobile device position directly. As a result, the electrical transmission path can be particularly short.

[0016] The locking system may comprise a retention latch switchable between a locked position in which the hook is held in the second position and a released position in which the hook is not held in the second position, the retention latch preferably being a component of the movement device already described above.

[0017] Preferably, the minimum distance between the detection device or sensor and the hook is at least 1 cm, preferably at least 3 cm, more preferably at least 5 cm or at least 10 cm.

[0018] The anchoring system is preferably telescopic in design, comprising a first section and a second section, which are displaceable relative to one another to adjust the length of the anchoring system (this should in particular be understood as meaning that the first and second sections can be moved relative to one another, in particular translationally, preferably longitudinally), an adjustment latch is preferably provided in or on the second section, which adjustment latch can be configured (or is adjustable) to optionally allow and / or only allow limited and / or not allow adjustment of the length of the anchoring system, and the first section is preferably optionally releasably attached or attachable to a child car seat or a base for a child car seat and / or is at least partly formed integrally with the child car seat or a base for a child car seat, and / or the second section is provided for optionally releasably attached to a vehicle seat (the vehicle seat having in particular a seat and a backrest).

[0019] Preferably, the second section of the locking system / said second section defines a lumen, for example formed by a duct section, and more preferably the displacement device / said displacement device is located mostly or entirely within the lumen, and the retention latch / said retention latch is also located partly, in particular mostly or entirely within the lumen.

[0020] Preferably, the second section / said second section of the anchoring system has a proximal end and a distal end, and the hook is located at the distal end.

[0021] Preferably, the first section has a plurality of at least 2, preferably at least 4, and / or up to 15, preferably up to 10 (e.g. 8 or 9 or 10) recesses longitudinally spaced from one another and each suitable for receiving a blocking part of an adjustment latch (see below). The distance between two recesses may be in the range of 1 cm to 2 cm, for example 15 mm, and / or at least 3% and / or up to 50% of the maximum total length. The recesses may in particular be through-holes.

[0022] In particular, the adjustment latch can selectively engage or disengage with the mating structure, in particular at least one of the longitudinally spaced recesses of the first section, for adjusting the second section relative to the first section in terms of the length of the locking system, and has a blocking portion, in particular the blocking portion already mentioned above, which can preferably assume at least one retracted position and / or which can assume an extended position, in particular the blocking portion is at least partially wedge-shaped.

[0023] Additionally or alternatively, the adjustment latch may have a first engagement portion, in particular for being held in the extended position, that may be suitable for interacting with a latch blocking portion of the moving element (see further below) to hold the adjustment latch in the extended position when the moving element (see further below) is in the second, non-driven position (see further below).

[0024] Additionally or alternatively, the adjustment latch preferably has a second engagement portion for holding it in the retracted position, which may be suitable for interacting with a drive portion of the moving element (see further below) so that the adjustment latch is driven to the retracted position when the moving element is moved to the drive position (see further below).

[0025] A free space can be provided adjacent to the first engagement portion (particularly as a recess between the first engagement portion and the second engagement portion) so that the latch prevention portion of the moving element faces the free space when the moving element is in the driving position, thereby preventing the latch prevention portion of the moving element from preventing the retention latch from switching to the retracted position.

[0026] Additionally or alternatively, the adjustment latch preferably comprises a third engagement portion, particularly as part of the locking portion, adapted to be contacted by the mating structure of the first section, particularly an edge of the recess, when a force urges the first and second sections toward one another to reduce the length of the locking system, the third engagement portion preferably being oblique to the longitudinal direction, whereby the adjustment latch is urged toward the retracted position by contact of the third engagement portion and the associated force.

[0027] The adjustment latch can be preloaded toward the extended position, particularly by at least a third spring. The adjustment latch can also be rotatable about a second axis, preferably stationary relative to the second section, and for this purpose can have a second axis portion or a second bearing portion. The third spring (or optionally at least one-third of the plurality of third springs) can be anchored to, particularly retained and / or attached to, the second axis of the adjustment latch and / or can be designed as a torsion spring.

[0028] Additionally or alternatively (especially if several third springs are provided), the third spring (or optionally at least one-third of the several third springs) can be anchored, in particular held and / or attached to the adjustment latch at a distance from the second axis and / or designed as a tension spring. Other types of springs are also conceivable, in particular two third springs can be provided (redundantly).

[0029] In the extended position of the adjustment latch, the side of the blocking part opposite the third engagement part can be arranged at least substantially perpendicular to the longitudinal direction (particularly forming an angle of 80° to 100° with the longitudinal direction). Additionally or alternatively, in the extended position of the adjustment latch, the side of the blocking part forming the third engagement part can form an angle with the longitudinal direction in the range of 35° to 55°, preferably 45°.

[0030] Preferably, the locking system is provided with a moving element (especially as already described above) arranged in the second section and / or on the surface thereof in a manner that allows for switchable displaceability, in particular longitudinal displaceability, between at least a first and a second non-driven position (especially as already described above) and a driven position (especially as already described above), the moving element having a drive (especially as already described above) suitable for selectively interacting with the (second / said second) engagement part of the adjustment latch to move the adjustment latch from the extended / said extended position to the retracted / said retracted position, preferably as a component of the above-mentioned moving device. The drive can be formed by a surface whose longitudinal direction is at least substantially such that it forms a surface normal.

[0031] Additionally or alternatively, the moving element comprises a latch blocking portion (especially as already mentioned above) suitable for selectively interacting with the (first / above-mentioned) engagement portion of the adjustment latch to prevent the adjustment latch from being moved from the extended position to the retracted position. The latch blocking portion may have a blocking surface that is straight in the longitudinal direction or inclined by at least 5° and / or at most 30°, preferably at most 20°, relative to the longitudinal direction. If the latch blocking portion is inclined, it is preferably such that it facilitates or allows the moving element to move from the second undriven position (in which the latch blocking portion blocks the adjustment latch from moving to the retracted position) to the first undriven position (associated with the locked position of the retention latch), even if a force is pushing the adjustment latch towards the retracted position.

[0032] Additionally or alternatively, the moving element is operatively connected to the retaining latch (particularly those already mentioned above) such that movement of the moving element, particularly by the actuating element, causes the retaining latch to switch between the released position and / or the locked position.

[0033] Preferably, the adjustment latch and the moving element are adapted to each other in such a way that a force for moving the adjustment latch from the extended position to the retracted position is transmitted by the first engagement portion to the latch blocking portion at a certain (not overwhelming) degree in terms of force, thereby propelling the moving element from the second non-driven position to the first non-driven position.

[0034] Preferably, the adjustment latch is designed as a single piece, possibly a one-piece structure.

[0035] The moving element may be preloaded, particularly by a second spring (see further below), toward a first, undriven position in which the latch block does not prevent the adjustment latch from moving from the extended position to the retracted position and the drive does not cooperate with the adjustment latch to move it from the extended position to the retracted position. In the first, undriven position, a limited range of adjustment of the length of the locking system may be permitted or possible. The moving element and the retention latch may be designed and arranged such that the retention latch is in a locked position when the moving element is in the first, undriven position. In one embodiment, the moving element comprises a second contact portion for abutting the first contact portion of the retention latch.

[0036] Additionally or alternatively, the moving element is preferably operatively connected to the retaining latch such that movement of the moving element, optionally by an actuation element (of the locking system), can release the retaining latch and switch it between a released position and / or a locked position. In particular, movement of the moving element by the actuation element can move the retaining latch from a locked position to a released position.

[0037] The transfer device can be made of (at least 10% by weight or at least 30% by weight) plastic and / or (at least 10% by weight or at least 30% by weight) metal. Preferably, at least the part of the transfer device that comes into contact with the hook is made of (at least 50% by weight or at least 80% by weight) metal, in particular steel, and / or the part of the transfer device that does not come into contact with the hook is made of (at least 50% by weight or at least 80% by weight) plastic.

[0038] The moving element can be made of plastic (at least 50% by weight or at least 80% by weight), in particular as an injection-molded part. The retaining bolt and the moving element can be rigidly connected to each other, for example by fastening means, and / or parts of the retaining bolt, in particular the first contact part, can be extrusion coated.

[0039] Depending on the embodiment, the retaining latch is made (at least 50% by weight or at least 80% by weight) of metal, in particular steel, and / or the moving element is made (at least 50% by weight or at least 80% by weight) of plastic, whereby in particular a high degree of stability is achieved in the relevant area on the one hand and weight and / or costs are saved on the other hand.

[0040] In an alternative embodiment, the retention latch and the moving element may be unitary in design.

[0041] Generally, the hooks, adjustment latches and / or retention latches may be made (at least 50% by weight or at least 80% by weight) of metal, especially steel.

[0042] The moving device, in particular the moving element, may have a second guide portion, optionally a guide groove or slot, and a third protrusion, optionally a guide pin or bolt, between the second section and the moving element, in particular by means of, for example, a gap.

[0043] Preferably, the moving device, in particular the moving element, is arranged directly on the second section and has a support that supports the moving device, in particular the moving element, on the second section and optionally allows the moving element to slide along the second section. The support can in particular be designed as a protrusion, and the support can preferably be provided at the height of the latch blocking part opposite the blocking surface.

[0044] According to one embodiment, the locking system may have, in addition to the adjustment latch, in or on the second section, a further adjustment latch, in particular a second adjustment latch, which can assume at least an extended position and a retracted position relative to the first section and the second section and which is suitable for selectively allowing or restricting adjustment of the length of the locking system. Reference should be made here to EP 3 600 954 B1, the disclosure of which is hereby incorporated into the present application, in which, for example, two adjustment latches are provided for adjusting the length of the locking system.

[0045] Preferably, when the hook is in the first position and the adjustment latch, in particular the second engagement part, is held in the retracted position by the moving device, in particular by interaction with the drive part of the moving element, the moving device is in particular in the third moving device position.

[0046] When the hook is preferably in the first position and the adjustment latch, in particular the first engagement portion, cannot be moved from the extended position to the retracted position by the moving device, in particular by interaction with the latch blocking portion of the moving element, the moving device is in particular in the second moving device position.

A first end of the second spring can be supported on the retention latch. A second end of the second spring can be supported on the second section. The hook and retention latch can be designed and arranged such that when the hook is in the first position, the hook holds the retention latch in the released position by the hook blocking portion, and further, when the hook is moved to the second position (e.g., by actuation of the actuation portion), the retention latch can be moved to the locked position, in particular by being driven by the second spring or the first / second spring.

[0070] The hook may have an engagement portion into which the retention latch slides to engage the locking portion when the hook is in the second position and the retention latch is in the locked position. The retention latch may have a first contact portion for contacting the moving element. The retention latch may also be L-shaped, in particular with an end of one arm of the L-shaped portion forming the locking portion and / or the other arm of the L-shaped portion forming (wholly or partially) the contact portion. The retention latch may be made (at least 50% by weight or at least 80% by weight) of metal, in particular steel.

The minimum and maximum length of the locking system can be determined by the lateral guide slot.

[0073] Preferably, the second section has an elongated hole that overlaps a portion of the lateral guide slot of the first section and guides movement of the second pin longitudinally, either toward or away from the first pin.

[0074] Preferably, the actuating element, in particular the actuating element already described above, is provided to be actuated, in particular manually (directly or indirectly), by a user.

Further preferably, the actuating element or its movable part can be blocked by a holding device, and a release actuating part can be provided to release the holding device. The actuating element, in particular its release actuating part, can comprise at least one knob and / or at least one button and / or at least one slider and / or at least one operating lever.

[0075] Preferably, the movable part of the actuation element can be moved relative to the fixed part (and thus also relative to the second section), in particular against the force of the fourth spring.

[0076] The locking system preferably has an installed position (see further below) in which the moving device is in the second moving device position, the hook is in the first position, the retention latch is preferably in the released position (held by the hook blocking portion of the hook), and more preferably the moving element is in the second non-driven position and the adjustment latch is in the extended position, in which case the release actuator / said release actuator (of the actuating element) has not been actuated by the user.

[0077] According to a preferred embodiment, when the user presses (hardly) the hook, and in particular its actuating part, against the vehicle side bracket, for example starting from the installed position in which the release actuating part / said release actuating part (of the actuating element) is not (yet) actuated, the moving device is moved from the second moving device position to the first moving device position, in particular the retaining latch is moved to the locked position, and more preferably the moving element is moved from the second non-actuated position to the first non-actuated position in which the adjustment latch is (still) in the extended position, and the hook is moved (by the actuating part being actuated by the vehicle side bracket) to the second position in which the two legs of the hook are engaged with the periphery of the vehicle side bracket, whereby the locking system is moved to the locked position (see below).

[0078] According to one preferred embodiment, when the user actuates, in particular gradually presses, for example the release actuator / said release actuator (of the actuation element) starting from the (current) locked position, the movement device is moved from the first movement device position to the second movement device position, in particular the movement element is moved (initially) from the first unactuated position to the second unactuated position (again), and more preferably the retention latch is (again) held in the released position by the hook blocking part of the adjustment latch, the adjustment latch is (now) (still) in the extended position and the hook is moved (by the pre-loaded first spring and / or first / second spring) to the first position, whereby the locking system is (again) moved to the installed position.

[0079] According to one preferred embodiment, when the user actuates, in particular gradually presses, for example the release actuator / said release actuator (of the actuation element) starting from the installed position, the movement device is moved from the second movement device position to the third movement device position, in particular the movement element is moved from the second non-driven position to the driven position, and more preferably the retention latch is (still) in the released position, the adjustment latch is driven to the retracted position and the hook is (still) in the first position, whereby the locking system is moved to the adjustment position (see further below).

[0080] According to a preferred embodiment, if the user, for example, starts from the adjustment position and no longer activates the release actuator / said release actuator (of the actuation element), in particular releases the release actuator (gradually or suddenly), the locking system is (again) moved to the installation position.

[0081] In a further embodiment, the actuating element / fixed part of said actuating element has a through hole or slot on its outside, in which a color indication is visible on the surface of the movable part to indicate the current position of the hook depending on the position of the movable part relative to the fixed part.

[0082] The actuation element may be provided on (directly on) at least one of the first section and the second section, or remote from the first section and the second section.

[0083] The detection device (of the locking system), in particular a sensor, is preferably suitable for detecting the position of the moving device, preferably of said retaining latch / retaining latch and / or said moving element / moving element, and the detection device may comprise a switch switchable between a first switch position and a second switch position, and switching of the moving device from the second moving device position to the first moving device, preferably switching of the retaining latch from the released position to the locked position and / or switching of the moving element from the second undriven position to the first undriven position, may be linked to switching of the switch from the second switch position to the first switch position (accompanied by movement of the hook to the second position), and / or switching of the moving device from the first moving device position to the second moving device, preferably switching of the retaining latch from the locked position to the released position and / or switching of the moving element from the first undriven position to the second undriven position, may be linked to switching of the switch from the first switch position to the second switch position (accompanied by movement of the hook to the first position).

[0084] The switch of the detector may be preloaded into one of two switch positions, preferably towards the first switch position.

[0085] Preferably, the switch / said switch of the detection device comprises a button, in particular a push button provided for pressing or depressing, a protruding position of the button being associated with a first switch position / said first switch position and a depressed position of the button being associated with a second switch / said second switch position (which may be recessed or recessed at least further into the switch housing than the protruding position) and / or in the first switch position / said first switch position a lever is arranged in an inclined position relative to the longitudinal direction of the locking system and is operated to move the button from the protruding position to the depressed position. , is suitable for switching the switch from the first switch position to the second switch position / said second switch position by a moving device, in particular a detection part of the moving element, whereby the lever is moved to a position extending in the longitudinal direction and / or transversely to the longitudinal direction, the lever being preferably movable by a return spring, in particular a switch spring, to return to the inclined position (whereby the button pushes the lever in the direction of the inclined position and the entire switch is preloaded in the direction of the first switch position) in such a way that the return spring, in particular the switch spring, moves the button from the pressed position to the extended position.

[0086] In this way, it is possible to ensure, by particularly simple means, that the switch (of the detection device) only detects the locked position of the retaining latch (and thus the second position of the hook) when this actually exists (because the movable element must in this case be in the first, non-driven position, so that the lever is not in a position extending longitudinally or transversely to the longitudinal direction and the push button is not pressed, but the switch is moved to the second switch position both when the movable element is in the second, non-driven position and when it is in the driven position).

[0087] Preferably, the moving device / moving device, in particular the moving element / sensing part of the moving element / sensing part, and the sensing device, in particular the sensor, are arranged between the adjustment latch and the proximal end of the second section (and / or, according to one embodiment, between the adjustment latch and the hook).

[0088] According to one embodiment, the detector is located behind the adjustment latch when viewed from the hook.

[0089] Preferably, the moving device / moving device, in particular the moving element / sensing part of the moving element / sensing part, has areas of different conductivity, preferably at least one first area made of metal and / or a second area made of plastic.

[0090] Preferably, the detection device comprises electrical means, in particular an electrical sensor. The detection device may be connected not to a mechanical display (mechanical notification device) for indicating the hook position and / or to an electrical display (electrical notification device) for indicating the hook position. Electrically detecting the hook position has the advantage that the information determined in this way can be flexibly used, for example, to control the (preferably electrical) display (notification device) and / or to allow or disallow other settings of the anchoring system and / or the child seat base and / or the child seat. In particular, it is also very easy to implement a display (notification device) whose display content depends on the position of multiple, in particular two, hooks. The display (notification device) can indicate the hook position, for example, visually or audibly.

[0091] Preferably, the detection device, in particular the sensor, of the locking system is designed as a conductivity sensor and / or resistance measuring device, in particular for detecting areas of different conductivity of the detection part / said detection part.

[0092] A change in the detection state of the locking position of the retention latch (optionally, switching of a switch (of the detection device) between a first switch position and a second switch position) can be associated with opening or closing an electrical circuit.

[0093] The sensing device, in particular a sensor or a switch, can be connected to other components by an electrical connection, in particular by an electrical cable.

[0094] Information regarding whether the detection device detects the locked position of the retention latch (and optionally whether the switch is in the first switch position or the second switch position) can be used to control other devices on the child car seat or child car seat base, for example: - the child car seat or child car seat base may be provided with a notification device (optionally visual or audible) that indicates the state of the child car seat or child car seat base being secured on the vehicle seat depending on whether the retention latch is detected as being in the locked position by the detection device; - alternatively or in addition, the child car seat or base for the child car seat may be provided with means, in particular positive protection means such as an inflatable bag or belt tightening means (e.g. the belt system of the child car seat), which are only permitted to be used when the detection device detects that the retention latch is in the locked position, The following points can be mentioned.

[0095] The anchoring system (as a whole) preferably comprises: - the hook is in the first position, the transfer device is in a third transfer device position, in particular the retention latch is in the release position, the transfer element is in the drive position, the adjustment latch is in the retracted position, the actuation element is actuated (in particular the user has actuated the release actuation, in particular it is (permanently) pressed and / or kept pressed), the switch / said switch of the detection device is in the second switch position / said second switch position, the anchoring system and thus the child seat or the base for the child seat is not anchored to the vehicle seat, whereby the length of the anchoring system is freely adjustable (between a minimum length and a maximum length), in particular the adjustment positions already mentioned above, and / or - the hook is in the second position, the transfer device is in the first transfer device position, in particular the retaining latch is in the locked position, the transfer element is in the first non-driven position, the adjustment latch is in the extended position, the actuation element is not actuated (in particular the user has not actuated the release actuation, in particular has not (progressively) pressed and / or kept pressed), the switch / said switch of the detection device is in the first switch position / said first switch position, whereby the anchoring system and thus the child seat or the base for the child seat is anchored to the vehicle seat, in a locked position, in particular the already mentioned locked position, in which the anchoring system can only decrease in length (in particular when a force acts on the first section or the child seat or the base for the child seat, respectively, whereby the first section and the second section are urged towards each other), and / or - installation positions, in particular the installation positions already mentioned above, in which the hook is in a first position, the transfer device is in a second transfer device position, in particular the retention latch is in a released position, the transfer element is in a second non-driven position, the adjustment latch is in an extended position, the actuation element is not actuated (in particular the user has not actuated the release actuation, in particular has not (progressively) pressed and / or kept pressed), the switch / said switch of the detection device is in a second switch position / said second switch position, and the anchoring system and thus the child seat or the base for the child seat is not anchored to the vehicle seat, whereby the length of the anchoring system may or may not be altered to a further limited extent, and / or - an intermediate position when the locking system has shortened from the locked position and the adjusting latch has not yet reached the next recess (in the first section) (in particular when the hook is in the second position, the retaining latch is in the locked position, the moving element is in the first non-driven position, the adjusting latch is in the retracted position, the actuating element is not actuated (in particular when the user has preferably not actuated the release actuating element, in particular not (progressively) pressed and / or kept pressed), and the locking system and thus the child seat or the base for the child seat is locked to the vehicle seat), in which the length of the locking system can increase somewhat (for example by at least 2 mm or at least 4 mm and / or at most 2 cm or at most 1 cm) until the adjusting latch engages in the previous recess (in the first section), in particular when the first and second sections are pulled apart can be moved to.

[0096] Similar to the locked position, this embodiment also allows the length of the locking system to be reduced in the intermediate position (especially when a force acts on the first section or on the child seat or on the base for the child seat, which causes the first and second sections to move towards each other). The possibility of some movement in the other direction in the intermediate position allows the user to establish at least one engagement with a previous recess, which in particular facilitates improved usability and safety.

[0097] Parts made of metal, especially perforated parts, including for example hooks and / or adjustment latches and / or retention latches, can have varying thicknesses, thereby having thinned areas that allow for smaller holes to be drilled. The thinned areas can be formed from areas of normal thickness by applying high pressure (e.g., by hitting with a hammer of some kind).

[0098] The above-mentioned problem is also solved by a child car seat or a base for a child car seat which comprises at least one anchoring system as described above, in particular compatible with Isofix anchors or anchors according to ISO standard 13216 or United Nations Economic Commission for Europe standard R145, in particular for anchoring the child car seat or the base for a child car seat to a vehicle seat, and preferably at least or exactly two anchoring systems as described above - in particular arranged next to each other.

[0099] Furthermore, the above problem is solved by a method for detecting the position of the hook and / or the position of the child seat or base of such a anchoring system, wherein the detection device, in particular comprising a sensor, is configured to detect whether the hook is in the first or second position and to indirectly detect each position, and / or the detection device, in particular the sensor, is spaced apart from the hook, in particular when the hook is in the first position and when it is in the second position.

DETAILED DESCRIPTION OF THE INVENTION

[0103] In the following description of the figures, the same reference numbers are used for identical and identically acting parts.

[0104] FIG. 1a shows a child car seat 10 with a anchoring system 100 according to the invention.

[0105] FIG. 1 b shows the child car seat 10 on a child car seat base 11 having a anchoring system 100 .

[0106] FIG. 1 c shows a child seat base 11 with a anchoring system 100 .

[0107] 2 shows a child car seat base 11 having a lower side 12 for being placed on the seat surface of a vehicle seat and a rear side 13 intended to face towards the back of the vehicle seat. Two first sections 110 of the anchoring system according to the invention are shown diagrammatically as being integrally formed with the child car seat base 11. The two first sections 110 are flush at the bottom with the lower side 12 of the child car seat base 11. They also do not protrude rearwards beyond the rear side 13.

[0108] FIG. 3 shows the second section 120 of the locking system, which has a proximal end 121 and a distal end 122 formed as end caps. Also shown on the side of the second section 120 is an actuating element 230 having a fixed portion 231, a movable portion 232, and a release actuating portion 234. The fixed portion 231 has a through-hole (not shown) on its exterior, within which a color marking on the surface of the movable portion 232 (not shown) can be seen to indicate the current position of the hook 130, shown in this figure in its second position, depending on the position of the movable portion 232 relative to the fixed portion 231. The release actuating portion 234 is not actuated, and the movable portion 232 is in its initial position. The hook 130 is located at the distal end 122 of the second section 120, as already shown in FIG. 3, and can be switched between a first position and a second position. In the second position, the hook 130 has a notch (not shown) at the distal end 122 of the second section 120.

[0109] In Figure 4, the same elements as in Figure 3 are shown, but in contrast to the latter, the release actuator 234 has been actuated and the movable part 232 is in the depressed position, and the hook 130 is in the first position, whereby the actuator part 134 of the hook is visible.

[0110] Figure 5 corresponds to Figure 3, and Figure 6 corresponds to Figure 4. However, in both cases the internal structure of the actuation element 230 can now be seen. It can be seen that the release actuation part 234 is mounted rotatably about an axis (not numbered). When this is actuated against the force of a spring (not shown), the end formed as a retaining device pivots downwards, allowing the movable part 232 to be pressed towards the proximal end 121. The movable part 232 is also pressed against the force of a spring (not shown), as a result of which the hook 130 is moved to the first position, as will be explained in more detail below.

[0111] 7 shows a locking system 100 according to the invention, which has a first section 110 and a second section 120. The first section 110 has on its underside a number of recesses 111, shown in this figure as through-holes. On the side facing the actuating element 230, not shown in this figure, the first section 110 also has lateral guide slots 112 through which extend a first pin 236 and a second pin 237, which are provided for connection to the actuating element 230. The locking system 100 according to the invention is in a maximum extension state.

[0112] 8 shows a locking system 100 according to the present invention, with only half of the first section 110 shown in this view for clarity. The locking system 100 is shown pulled back relatively far in this view, and the first pin 236 can be seen to be rigidly connected to the second section 120. Additionally, the second section can now be seen to have an elongated hole 127 through which the second pin 237 extends.

[0113] 9 shows that second section 120 comprises first and second halves 120a, 120b, and end cap 120c. Additionally, hook 130 is visible along with first / second spring 131, and moving element 160 is visible along with retention latch 138, first pin 236, adjustment latch 200, and elongated hole 127.

[0114] 10 again shows a complete representation of a locking system 100 according to the present invention, having a first section 110 and a second section 120. In the first position shown, the hook 130 can be seen supported on the first protrusion 123 of the second section. The retention latch 138 is in the released position and is connected to the moving element 160. The third protrusion 125 connects the two halves 120a and 120b of the second section 120 and provides additional stability to the second section 120. The third protrusion 125 of the second section 120 increases the mechanical stability of the second section and, together with the gap 166 in the moving element 160, can also form the second guide 102 as a side effect.

[0115] Further details can be seen in the enlarged view of portions of the adjustment latch 200 and moving element 160 shown at the bottom of the figure. The adjustment latch 200 has a blocking portion 201 that is wedge-shaped. As shown, the first engagement portion 202 cooperates with the latch blocking portion 162 to prevent the adjustment latch 200 from moving from the extended position shown, where the blocking portion 201 engages with one of the recesses 111 in the first section 110, to the retracted position. Opposite the latch blocking portion 162, the moving element 160 has a support portion 165 by which the moving element 160 can be supported on the second section 120.

[0116] The second engagement portion 203 of the adjustment latch 200 is located opposite the drive portion 161 of the moving element 160 and is intended to interact with the latter to move the adjustment latch 200 from the extended position to the retracted position. However, in the illustrated position of the moving element 160, the drive portion 161 and the second engagement portion 203 are spaced apart from each other.

[0117] Between the first engagement portion 202 and the second engagement portion 203 there is a free space 204 in which the latch blocking portion 162 is located when the moving element 160 is in the drive position. On the side of the blocking portion 201 facing the proximal end 121 there is a third engagement portion 208 intended to cooperate with the edge of the recess 111 in which the adjustment latch 200 is engaged in order to urge the adjustment latch 200 towards the retracted position.

[0118] The adjustment latch 200 is pivotable about a second axis 206, on which it is mounted by a second bearing 207. Two third springs 205, one a torsion spring and the other a tension spring, pull the adjustment latch 200 towards the extended position. The third springs 205, which are designed as torsion springs, are supported at one end on the first latch 200 and at the other end on the fourth protrusion 126 of the second section 120.

[0119] The third spring 205, which is designed as a tension spring, is supported at one end on the adjustment latch 200 and at the other end on the second section 120. It can be seen that the support point of the third spring 205, which is designed as a tension spring, is thinner than the rest of the adjustment latch 200. In the extended position shown, the adjustment latch 200 is supported on the fourth protrusion 126.

[0120] 11 also shows the second section 120 of the locking system 100 according to the present invention. A hook 130 having a locking portion 135 is disposed at the distal end 122, and the hook 130 is rotatably mounted about a first axis 132 by a first bearing portion 133. A first / second spring 131 is anchored at a first end 131 a to the hook 130, specifically generally above the first bearing portion 133, and at a second end 131 b to an arm of an L-shaped retention latch 138.

[0121] The retaining latch 138 is movable together with a moving element 160 which has, inter alia, a drive part 161 and a detection part 164. In the illustrated adjustment position of the anchoring system 100 according to the invention, the hook 130 is in the first (open) position, the retaining latch 138 is in the released position, the moving element 160 is in the drive position, the adjustment latch 200 is in the retracted position and the actuation element 230 (not shown) is actuated. Thus, the child seat 10 connected to the anchoring system 100 or the child seat base 11 connected to the anchoring system 100 is not anchored to the vehicle seat 1 and the length of the anchoring system 100 can be freely adjusted between a minimum length and a maximum length. A detection device 180 is shown diagrammatically (see also FIG. 13).

[0122] Figure 12 shows the same elements as in Figure 11, but the locking system 100 according to the invention is now in the installed position. Furthermore, the hook 130 is in the first position (open) and the retaining latch 138 is in the released position. However, the moving element 160 is now in the second, undriven position and the adjusting latch 200 is in the extended position. The actuating element 230 (not shown) has not been actuated. The locking system 100 is no longer locked to the vehicle seat 1 and the length of the locking system 100 cannot be changed because the latch blocking portion 162 of the moving element 160 blocks the adjusting latch 200 at the first engaging portion 201 and holds it in the extended position.

[0123] 11 and 12, but now with the anchoring system 100 according to the invention in the locked position. The hook 130 is now in the second position, the retaining latch 138 is in the locked position, and the moving element 160 is in the first, undriven position. The adjustment latch 200 is in the extended position, and the actuation element 230 (not shown) is not actuated. The anchoring system 100, and optionally the child seat 10 or child seat base 11 connected to the anchoring system 100, are now anchored to the vehicle seat 1, and the length of the anchoring system 100 cannot be increased, but can only be decreased when a force acts on the first section 110 or the child seat 10 or child seat base 11, respectively, urging the first section 110 and the second section 120 towards each other. It can be seen that the detector 180 is now no longer facing the detector portion 164, so that a distinction can be made between the locked and released positions of the retention latch 138 (and therefore between the first and second positions of the hook 130).

[0124] Figure 14a and the associated enlarged view according to Figure 14b essentially correspond to Figure 11, with the locking system in the adjusted position and the detection device comprising in particular a sensor 181 in the form of a switch 182, which can be better seen in the enlarged view. The switch 182 has a housing 183 and is in the second switch position. The lever 185 is at least essentially longitudinally oriented and therefore not easily visible.

[0125] Figure 15a and associated enlarged view 15b essentially correspond to Figure 12, with the locking system in the installed position. Figures 15a and 15b, like Figures 14a and 14b, also show a specific sensor 181 in the form of a switch 182. It can be seen that the detector is still depressing the lever 185 of the switch 182, which causes the (still invisible) push button 184 to be recessed into the housing, with the switch (still) in its second switch position.

[0126] Figure 16a and the associated enlarged view according to Figure 16b essentially correspond to Figure 13, with the locking system in the locked position. Figures 16a and 16b also show a sensor 181, which is preferably designed as a switch 182, as already shown in Figures 14a to 15b. Here, the sensing part 164 has moved so far towards the distal end 122 of the second section 120 that the switch spring (not shown) now pushes the recognizable push button 184 into the extended position and the lever 185 has been moved to the tilted position. The switch of the sensor 181 is therefore in its first switch position.

[0127] 17a and 17b also show very diagrammatically possible basic forms of interaction between the components of the locking system 100, in particular the second section 120, in particular the hook 130, the moving element 160 (in particular the retaining latch 138) and the sensor 181 (in particular the push button 184, the lever 185 and the return spring 186). Figure 17a shows the switch 182 in a first switch position at a distance from the detector 164, in particular with the push button 184 in a protruding position, the lever 185 in a tilted position and a relaxed switch spring 186 (designed exemplarily as a compression spring in this figure). Figure 17b shows the switch 182 in a second switch position, in particular with the lever 185 pressed into a straight position (transverse to the longitudinal direction in this figure) by the detector 164 which presses down the push button 184 against the force of the switch spring 186.

[0128] For technical reasons, the springs are not always shown accurately in some of the drawings.

[0129] It should be noted here that all the above-mentioned components, in particular the details shown in the drawings, are claimed as essential to the invention when considered both individually and in any combination, modifications of which will be familiar to those skilled in the art.

[0130] Furthermore, it should be noted that the aim is to achieve the widest possible scope of protection. In this regard, the disclosure contained in the claims can also be specified by the features described together with further features, even if these further features are not necessarily to be included. It is expressly pointed out that parentheses and the word "in particular" are intended to emphasize that a feature is optional in the respective context (which does not mean, on the contrary, that, in the absence of such specification, a feature should be considered as essential in the corresponding context).
