Description

Anchoring system for safety belts of a child safety seat
The invention relates to an anchoring system for safety belts used with a child safety seat. In particular, the invention relates to an anchoring system that comprises multiple coupling devices each for use with different sized children.
Smaller children, such as babies or toddlers, are held securely in a safety seat mounted on a passenger seat of a vehicle with a special child restraint system, such as an integral harness system attached to the seat. For this age group, an integral harness attached to the safety seat with a 5-point harness using a harness buckle as a coupling device is considered to be the safest securing means. The 5-point harness of the safety seat firmly secures the child’s shoulders and hips in the seat.
For older children, however, there is an increasing need for flexibility and movement which needs to be met by the child restraint system. Older and larger children can use the vehicle mounted 3-point adult seat belt with a highback booster seat, as this correctly positions the 3-point adult seat belt in relation to the child's body. As a child moves around, however, the adult lap belt may not stay correctly positioned across the pelvic region. An additional safety belt clip coupled to a seating portion of the child safety seat which engages the lap portion of the 3-point safety belt can help to secure the lap portion of the safety belt across the pelvic region. The safety belt clip serves as a fourth anchor point to the standard 3point adult passenger seat belt.
Such a safety belt clip is described in EP 3031 664 Al. The safety belt clip comprises a guiding element with an engaging element and a positioning component. The positioning component is adapted to position the engaging element at a distance from the seating portion and the engaging element is adapted to engage with the lap portion of the 3-point safety belt. Furthermore, the guiding element is configured to hold the lap portion of the safety belt over the pelvic region of an older child secured in the child safety seat with the 3-point safety belt.
A combination child seat allows the use of different safety systems for both young and older children in the same seat. When used for a young and smaller child, the integral harness system of the combination child seat is used to secure the child. The integral harness may be either a 3-point or a 5-point harness. A 3-point harness comprises two shoulder straps. At the end of each shoulder strap there is a tongue member adapted to engage with a harness buckle. The upper ends of each shoulder strap are firmly coupled to the combination child seat. A 5-point harness also comprises two straps. The upper end of each strap is connected to the seating portion of the combination child seat. A tongue member is
2018256574 31 Oct 2018 slideably engaged with each strap. The two tongue members are inserted into the harness buckle for securing the child. The lower portions of the strap, which extend from the tongue member to the seat, are positioned over the pelvic region of the child. The upper portion of the straps extending from the tongue members to the backrest of the combination child seat are positioned over the shoulders of the child.
Once a child grows, they can be secured in the combination child seat using the safety belt of the vehicle. The integral harness system can then be disconnected from the seat and stored. Therefore, the combination child seat can be used over a larger range of a child’s early life.
One aspect of the present invention is to provide multiple options in a combination child seat to assist in restraining different aged and different sized children.
According to a first aspect of the invention there is provided an anchoring system for a child safety seat comprising a first coupling device adapted to engage with a harness of the child safety seat, a second coupling device adapted to engage with a safety belt of a vehicle, one or more anchoring means adapted to anchor the first and the second coupling device, and a storage system adapted to store at least one of the first coupling device or the second coupling device depending on which of the coupling devices is not in use.
In a further aspect of the invention, when there is a first and second coupling device, the anchorage system is configured with the first coupling device in its active position, the anchoring means holds the first coupling device with respect to the safety seat. In this active position, the first coupling device is placed in a position for engaging with the harness of the child safety seat. With the first coupling in its active position, the second coupling means is stored in the storage system.
Further, when the anchorage system is configured with the second coupling device in its active position, the anchoring means holds the second coupling device with respect to the safety seat. In this active position, the second coupling device is placed in a position for engaging with the safety belt of the vehicle. With the second coupling device in its active position, the first coupling device is stored in the storage system.
In this further aspect of the invention, the anchoring system is configured to be installed in a seating portion of the child safety seat. Since each of the first and the second coupling device may be placed in an active and an inactive position, the child safety seat easily accommodates smaller children as well as older children and therefore has an extended life cycle. For smaller children, the anchoring system is used with the first coupling device in the active position for engaging with the harness of the child
2018256574 31 Oct 2018 safety seat. In this case, the second coupling device may be stored in the storage system. For older children that are too tall to be secured with the integral harness of the child safety seat, the anchoring system is used with the second coupling device in the active position. The second coupling device is adapted to engage or hook onto the vehicle seat belt. In this configuration, the first coupling device is stored in the storage system, thus, being in the inactive position. In this configuration, a child may be secured by the safety belt of the vehicle. The safety belt of the vehicle engages in this case with the second coupling device. This ensures that the lap portion of the safety belt is secured properly across the pelvic region of the child.
The storage system allows for easy storage of the first or second coupling device. The storage system is incorporated into the safety seat as part of the anchoring system. This ensures that the storage system works in combination with the anchoring system to provide a storage location for the coupling device not being used and ensures that when the configuration of the anchorage system is being changed, the alternate coupling device is immediately obvious to the user and readily to hand. It is also immediately 15 obvious where to store the unused coupling device. This arrangement avoids the design option of having the unused coupling device being removable for storage away from the seat and therefore avoids the risk of the component becoming misplaced or lost. It also avoids the safety seat being used in a noncompliant manner or not being usable at all.
Preferably, the anchoring system is configured such that the first coupling device is in the active 20 position when the second coupling device is in the inactive position; and the anchoring system is configured such that the second coupling device is in the active position when the first coupling device is in the inactive position. The effect is that the user is induced to always use one of the safety systems to properly secure the child in the child safety seat.
In a further aspect of the invention, the storage system is adapted to store both the first and the second 25 coupling devices at the same time. Preferably, the storage system comprises two pockets; the first pocket is adapted to store the first coupling device and the second pocket is adapted to store the second coupling device. The advantage of storing both the first and second coupling devices in the storage system is that the child safety seat may be used as a highback booster seat for older children. In this case, the child is secured with the safety belt of the vehicle only. For older children, the use of a second 30 coupling device, such as a safety belt clip, may not be necessary anymore. The storage system which is adapted to store both coupling devices together has the advantage of avoiding the chance of both coupling devices being misplaced or lost while not being used.
Alternatively, the storage system may be adapted to store only one of either the first or second coupling
2018256574 31 Oct 2018 device at the one time. Since the storage system is adapted to store either the first or the second coupling device, the user is induced to apply at least one coupling device and secure the child in the safety seat by anchoring either the harness of the child safety seat or the safety belt of the vehicle. This design has the advantage of reducing the size of the storage system.
In a still further aspect of the invention, the first coupling device and the second coupling device are coupled by a coupling mechanism such that moving the first coupling device into the active position causes the second coupling device to be moved into the inactive position, and vice versa.
Preferably, the coupling mechanism is adapted to move the first coupling device into the active position when the second coupling device is moved into the inactive position, and in turn, move the second coupling device into the active position when the first coupling device is moved into the inactive position. Preferably, the coupling mechanism comprises a cable element, such as a belt, a wire or a chain. This has the advantage that moving one coupling device automatically moves the other coupling device in the required direction. Since displacement of both coupling devices is controlled by the coupling mechanism, the movement of one coupling device by the user is sufficient for bringing the other coupling device into the correct position. The adjustment of the anchoring system is therefore easier and faster.
Advantageously, the anchoring means comprises a rail system, wherein the first coupling device and the second coupling device are each transferable along the rail system between the respective active position and the respective inactive position. Preferably, the rail system comprises a first rail and a second rail, wherein the first rail is adapted to anchor only the first coupling device and the second rail is adapted to anchor only the second coupling device. Rails have the advantage that the coupling devices stay connected to the rail system or each of the separate rail systems. The risk that the inactive coupling devices become misplaced or lost is greatly reduced. Furthermore, the rails facilitate easy shifting of the coupling devices from the active to the inactive position and vice versa. The handling becomes more intuitive. Furthermore, it assists in having the first and second coupling devices placed in the correct position.
Since the first coupling device is adapted to be used with the harness system of the child safety seat, the anchoring system with the active first coupling device is preferably used for smaller children. The active second coupling device is used for older children. It is, therefore, further advantageous that the active first coupling device is positioned closer to the backrest of the child safety seat than the active second coupling device when the anchoring system of the invention is used in a child safety seat. As the children grow, they occupy more space on the seating area of the child safety seat. Therefore, it is advantageous that the active second coupling device is positioned further away from the backrest of the
2018256574 31 Oct 2018 child safety seat than the active first coupling device. This improves the location of both coupling devices to better accommodate for different sizes and ages of the child occupying the child safety seat.
It is also possible that the anchoring means / rail system comprises one rail which is adapted to anchor the first and the second coupling device. This has the advantage of simplifying the production process of the child safety seat.
In an alternative to rails, the anchoring means may comprise one or more slots. Preferably, the anchoring means comprises two slots, a first slot adapted to anchor the first coupling device and a second slot adapted to anchor the second coupling device. The first or second coupling device may be anchored in the anchoring means by a hinging means that allows the first or second coupling device to hinge with respect to each slot. It is also possible for the anchoring means to use only one slot which is adapted to anchor both the first and second coupling device.
Advantageously, the first coupling device is a harness buckle adapted to engage with tongues of the harness of the child safety seat, and the second coupling device is a safety belt clip adapted to engage with a lap portion of the safety belt of the vehicle seat. This has the advantage that smaller children are secured by engaging the 5-point safety belt of the child safety seat in the harness buckle, and older children are secured by engaging the lap portion of the 3-point safety belt of the vehicle seat in the safety belt clip.
Preferably, the anchoring system further comprises at least one lid adapted to cover the storage system. The at least one lid ensures, when in the closed position, that the seating area of the child safety seat is fully covered. That is, when the child safety seat is used with the anchoring system of the invention, the comfort of the child sitting in the child safety seat is not influenced by the storage system. Advantageously, the first or the second coupling device is locked in the active position when the at least one lid is closed. Preferably, the at least one lid locks the first or second coupling device in the active position against side movement. This has the advantage that the active coupling device is secured and is not displaced unintentionally. Furthermore, the user is induced to close the at least one lid of the storage system in order to use the child safety seat correctly and thus secure the coupling device in its active position. If the storage system comprises two or more pockets, then the anchoring system preferably comprises two or more lids, each adapted to cover a respective pocket.
Advantageously, the anchoring means is configured such that the active position of the first coupling device is distant from the active position of the second coupling device to accommodate children of different age and size. This configuration of the anchoring means takes into account the different sizes and ages of the children. While the configuration with an active first coupling device is used for smaller
2018256574 31 Oct 2018 children, the configuration with the second coupling device is used for older children. In particular, when the anchoring system is installed in a child safety seat, the placement of the second coupling device further away from the backrest of the child safety seat than the first coupling device places the second coupling device in the correct position for older children
Advantageously, the coupling devices may also have different lengths to accommodate for children of different age and size. Preferably, the second coupling device is longer than the first coupling device.
Furthermore, the coupling devices advantageously comprise adjustment means, such as for example 10 adjustable straps that may be included in the adjustment means to accommodate children of different age and size. An advantage is that the safety belt is adjustable to the child providing better comfort and protection.
According to another aspect of the present invention, there is provided an insertion tongue, adapted to be inserted into a coupling device for anchoring a harness of a child safety seat, comprising an engaging 15 element and a coupling element, wherein the engaging element is adapted to engage with the lap portion of a safety belt of a vehicle, and the coupling element is adapted to engage with the coupling device. The coupling device for anchoring the harness of a child safety seat is preferably a harness buckle of a harness system.
Preferably, the insertion tongue is configured as a safety belt clip adapted to be inserted into the harness buckle. An advantage is that the coupling device does not need to be dismounted and stowed away in order for the child safety seat to be used with the safety belt of the vehicle. Since the insertion tongue may be inserted in the coupling device, no cumbersome conversions of the child seat are necessary. It is sufficient to insert the insertion tongue into the coupling device. In this configuration, the child safety seat can still be used even for older children. The coupling element of the insertion tongue is preferably a latch. The coupling element may be inserted in the coupling device. The coupling device preferably comprises a slot for receiving the coupling element of the insertion tongue. The engaging element of the insertion tongue is adapted to receive the lap portion of the safety belt of the vehicle. Because of this, the engaging element ensures that the lap portion of the safety belt is properly guided across the pelvic region of the occupant of the child safety seat. The insertion tongue is advantageously configured to be removed from the coupling device by activating a release button of the coupling device. Advantageously, the insertion tongue is configured to be adjusted by rotation or linear movement. This allows for an adaptation of the insertion tongue to the geometry of the safety belt and to the size and age of the occupant.
A further advantage of the insertion tongue according to the invention is that useful life of the child
2018256574 31 Oct 2018 safety seat is extended and the child safety seat can be used over a larger range of children’s ages without replacing the harness buckle that is anchored on the seating surface. Another advantage is that the safety belt clip may be arranged at a higher position than the harness buckle better accommodating the taller size of older children.
Advantageously, the insertion tongue is secured to the child safety seat by a flexible element. An advantage is that the insertion tongue is attached permanently close to the coupling device. It will not get lost as easily.
According to another aspect of the present invention, there is provided a combination coupling device for a child safety seat comprising a fixation element for coupling the combination coupling device to the child safety seat, and a coupling device, wherein the coupling device is adapted to engage with a tongue of a harness system of the child safety seat, and further adapted to engage with a lap portion of a safety belt of a vehicle seat. An advantage is that both a coupling device adapted to engage with the harness of a child safety seat, and a coupling device adapted to engage with a safety belt of a vehicle, are integrated into one combination coupling device. There is, thus, no need to exchange, store, displace or activate different coupling devices.
Advantageously, the coupling device is a harness buckle adapted to engage with a buckle tongue of the harness of the child safety seat, and the coupling device comprises an integrated safety belt clip adapted to engage with a lap portion of the safety belt of the vehicle seat. Preferably, the coupling device comprises a slot for receiving the tongue of the harness. An advantage is that both the harness buckle of the child safety seat and the safety belt clip engaging with the lap portion of the safety belt of the vehicle seat are integrated into one device.
Advantageously, the combination coupling device is configured to be adjusted by rotation or linear movement. This allows for an adaptation of the combination coupling device to the geometry of the safety belt and to the size and age of the occupant. Preferably, when used in a child safety seat, this allows for bringing the combination coupling device closer to the occupant of a child safety seat. Further, this allows for an adjustment of the geometry of both the harness and of the safety belt of the vehicle depending on the size and age of the child.
Advantageously, the combination coupling device further comprises a release button for releasing the tongue upon activation, wherein the safety belt clip is integrated in the release button of the harness buckle. This allows to release the harness or the safety belt straightforwardly with a single grasp, for example, to take the child out of the seat in case of an emergency of after an accident.
2018256574 31 Oct 2018
Advantageously, the harness buckle comprises a protective lid to prevent dirt or dust from entering the harness buckle. An advantage is that there is less dirt or dust entering the harness buckle that may otherwise be unprotected. This is particularly advantageous when the safety belt clip of the combination coupling device is used. In this configuration, the integral harness of the child safety seat may be stowed 5 away. The slot for the insertion of the harness tongue would remain open if no lid were used.
Another aspect of the invention relates to a child safety seat comprising the anchoring system of the invention, the insertion tongue of the invention, or the combination coupling device of the invention.

Figure 11b shows a combination coupling device engaged with a lap portion of a seat belt.
Figure 1 shows a child safety seat 100 equipped with an anchoring system 30 comprising a first 5 coupling device 10 and a second coupling device 20 in accordance with the invention. The child safety seat 100 comprises a seating portion 50 and a backrest 60. The seating portion 50 and the backrest 60 may be separate parts or may be integrally formed. The anchoring system 30 is installed in the seating portion 50 of the child safety seat 100.
The first coupling device 10 shown in Fig. 1 is a harness buckle intended for use with a harness of the child safety seat 100. The second coupling device 20 is a safety belt clip intended for use with a lap portion of a safety belt of a vehicle seat. The safety seat harness and vehicle safety belts are not shown in Fig. 1.
The anchoring system 30 further comprises an anchoring means 80, 85 adapted to receive and to anchor the first coupling device 10 and the second anchoring device 20. The anchoring means 80, 85 shown in Fig. 1 is given by a first slot 80 and a second slot 85. The first coupling device 10 shown in Fig. 1 comprises a first engaging element 101 and a first positioning element 102. The details of the first coupling device 10 are described below with respect to Fig. 2a. The first coupling device 10 is attached 20 to a first socket plate 70. The first socket plate 70 ensures that the first coupling device 10 may be firmly anchored in the first slot 80. When anchored in the first slot 80, the first coupling device 10 is in the active position. In said active position, the first coupling device 10 is placed such that the tongues of the harness may be inserted. According to the embodiment shown in Fig. 1, the anchoring of the first coupling device 10 in the first slot 80 is accomplished by hinging the coupling element 10 into the first 25 slot 80. The anchoring system 30 further comprises a second slot 85 for receiving and anchoring the second coupling device 20. The second coupling device 20 comprises a second engaging element 201 and a second positioning element 202. The details of the second coupling device 20 are described below with respect to Fig. 2b. The second coupling device 20 shown in Fig. 1 is stored in the storage system 110. The storage system 110 may be formed as a pocket, recess or cavity in the anchoring system 30.
When stored in the storage system 110, the second coupling device 20 is in the inactive position, and so it is not possible for the second coupling device 20 to engage with the safety belt of the vehicle. The second coupling device 20 is attached to a second socket plate 75. The latter ensures that the second coupling device 20 may be firmly anchored in the second slot 85 of the anchoring means. When placed in the anchoring means, the second coupling device 20 is active. This means that the second coupling 35 device may engage with the safety belt of a vehicle.
A storage system 110 is provided for storing either the first coupling device 10 or the second coupling
2018256574 31 Oct 2018 device 20 or both. The anchoring system 30 further comprises a lid adapted for covering the storage system.
In order to secure a smaller child with the harness of the child safety seat 100, the first coupling device 5 10, which in the embodiment shown in Fig. 1 is a harness buckle, is anchored in the first slot 80 of the anchoring means through the socket plate 70. When anchored in the first slot 80, the first coupling device 10 is positioned closer to the backrest 60 of the child safety seat 100 than if it were anchored in the second slot 85. This configuration is particularly adapted for small children. Small children are secured in the child safety seat 100 by the integral harness. The tongues of the integral harness may be 10 inserted in the first coupling device 10. Since small children occupy only a smaller portion of the seating area of the child safety seat's seating portion 50, it is preferred that the first coupling device 10 is placed closer to the backrest 60, thus, closer to the child.
The second coupling device 20 in Fig. 1 is shown in its inactive position. The configuration shown in Fig. 1 corresponds to a child safety seat used for smaller children. However, once the child gets older, it 15 will be necessary to convert the child safety seat into one which is used with the safety belt of the vehicle. This conversion of the safety seat is described in detail with respect to Figs. 3a-3d below. The second coupling device 20, which in Fig. 1 is shown as a safety belt clip, can be anchored in the second slot 85 rather than in the first slot 80, thus providing more space and flexibility according to size and age of an older child that can use the safety belt of the vehicle seat.
Figure 2a shows the first coupling device 10 of Fig. 1. According to this embodiment, the coupling device 10 comprises a first engaging element 101 and a first positioning element 102. Further a socket plate 70 is shown. The first coupling device 10 is attached to the socket plate 70. In Fig. 2a it is shown that the positioning element 102 is attached to the socket plate 70. The first engaging element 101 is the 25 harness buckle of a harness system. The first positioning element 102 is a strap. The positioning element 102 ensures that the first engaging element 101 is placed at proper position for receiving the tongue of the harness. It further ensures that there is minimal free play for the first engaging element 101 so that the harness is firmly tightened. Instead of, or in addition to a strap, the positioning element 102 may comprise a semi-flexible or rigid element which is adapted to position and hold the engaging element 30 101 clear of the seating portion 50 of the child safety seat 100. This makes the first coupling device 10 more robust and more easily accessible. Preferably, the coupling device 10 may be adjustable to different sizes and ages of children. Advantageously, the length of the positioning element 102 is adjustable. The positioning element 102 therefore functions as an adjustment means to change the length of the strap.
Figure 2b shows the second coupling device 20 of Fig. 1. The second coupling device 20 comprises a
2018256574 31 Oct 2018 second engaging element 201 and a second positioning element 202. Furthermore, it is shown that the second coupling device 20 is attached to a second socket plate 75. The second coupling device 20 is a safety belt clip. The engaging element 201 is adapted to receive the lap portion of a safety belt of a vehicle. The shown engaging element 201 is formed as a hook. The positioning element 202 is configured to position the engaging element 201 at a distance from the seating portion 50 of the child safety seat. The positioning element 202 ensures that the second engaging element 201 is placed at a proper position for receiving the lap portion of the safety belt of a vehicle. The positioning element 202 may comprise a strap, a semi-flexible or a rigid element. Using flexible and/or rigid elements which are adapted to position the engaging element 201 at a distance from the seating portion 50 has several advantages. The first advantage is that the safety belt of the vehicle when engaged with the engaging element 201 of the coupling device 20 is properly guided across the pelvic region of the occupant. Second, the insertion of the safety belt into the coupling device 20 is made easier as it is held elevated from the seat surface which will allow connection by one hand only. Preferably, the coupling device 20 may be adjustable to different sizes and ages of children.
Advantageously, the length of the positioning element 202 is adjustable. For instance, the length of the strap and/or that of the semi-flexible or rigid element may be adjusted. Preferably, the length of the positioning element 202 of the second coupling device 20 is larger than the length of the positioning element 102 of the first coupling device 10. This is due to the first coupling device 10 being generally used for smaller children, while the second coupling device 20 is generally used for larger children. The positioning element 202 therefore functions as an adjustment means.
Figure 2c shows a first embodiment of the anchoring system 30 in accordance with the invention. There are shown a storage system 110, a first coupling device 10, a second coupling device 20 and a lid 115 of the storage system 110. The first coupling device 10 shown in Fig. 2c is a harness buckle as described in relation to Fig. 2a. The second coupling device 20 shown in Fig. 2c is a safety belt clip as described in relation to Fig. 2b. The lid 115 serves as an anchoring means for both the first and the second coupling device 10 and 20. The first coupling device 10 is anchored in the first slot 80 of the anchoring means / lid 115. The second coupling device 20 is anchored in the second slot 85 of the anchoring means / lid 115. The first 10 and second 20 coupling devices are anchored to the respective slots 80 and 85 with the help of respective socket plates (in Fig. 2c only the socket plate 75 of the second coupling device 20 is visible). In accordance with this embodiment, the first 10 and the second 20 coupling device are tightly fixed to the anchoring means / lid 115. In other words, the anchoring means / lid 115 couples the first 10 and second 20 coupling device such that the movement of the lid 115 causes the movement of both coupling devices. The lid 115 functions as a coupling mechanism. The first coupling device 10 extends towards one direction from the lid 115, the second coupling device 20 extends towards the opposite direction from the lid 115. The storage system 110 is dimensioned such that it may receive either one of
2018256574 31 Oct 2018 the first 10 and second 20 coupling device.
Figure 2d shows the anchoring system 30 in accordance with the first embodiment with the first coupling device 10 in the active position. When placed in this configuration, the first coupling device 10 5 is ready for receiving the tongue of a harness of a child safety seat. The first coupling device 10 is, therefore, in the active position. The second coupling device (not visible in Fig. 2d) is stored in the storage system. The second coupling device is, thus, in the inactive position. In Fig. 2d only the socket plate 75 which anchors the second coupling device to the second slot 85 of the anchoring means / lid 115 is visible. The storage system is covered by the lid 115. The lid 115, in the closed position, is 10 locked. Therefore, the first coupling device 10 is also firmly locked in the active position.
Figure 2e shows the anchoring system 30 in accordance with the first embodiment with the second coupling device 20 in the active position. When placed in this configuration, the second coupling device 20 is ready for receiving the lap portion of a safety belt of a vehicle. The second coupling device 20 is, therefore, in the active position. The first coupling device (not visible in Fig. 2e) is stored in the storage 15 system. The first coupling device is therefore in the inactive position. In Fig. 2e only the socket plate 70 which anchors the first coupling device in the first slot 80 of the anchoring means / lid 115 is visible. The storage system is covered by the lid 115. The lid 115, in the closed position, is locked. Therefore, the second coupling device 20 is also firmly locked in the active position.
For transferring the first coupling device 10 from its active position (as shown in Fig. 2d) to its inactive 20 position, results at the same time in transferring the second coupling device 20 from its inactive position to its active position (as shown in Fig. 2e). This may be done as follows. First, the lid 115 is removed from the storage system 110. This may be accomplished by lifting the lid 115 and/or sliding it backwards. As described above, the first 10 and second 20 coupling device are tightly fixed to the lid 115. Once the lid 115 is removed, the lid 115 may be turned around. When turning around the lid 115 25 the first 10 and second 20 coupling device interchange their orientations and positions. That is, by simply fuming around the lid 115, the first 10 and second 20 coupling device automatically interchange orientations and positions. Afterwards, the lid 115 is closed, e.g., by sliding it along the upper part of the storage system 110 until it is locked. The first coupling device 10 is then stored in the storage system 110. The first coupling device 10 is therefore in the inactive position. The second coupling device 20 is 30 placed in the active position. Since the first 10 and the second 20 coupling device are coupled to one another by the lid 115, there is always one coupling device in the active and the other in the inactive position. The placement of one coupling device in the active position automatically causes the other coupling device to be placed in the inactive position.
Figures 3a-3d show different configurations of an anchoring system 30 of a second embodiment of the
2018256574 31 Oct 2018 invention. In Fig. 3a first the coupling device 10 is anchored in the first slot 80 of the anchoring means. The second slot 85 is not used in this case. The coupling device 10 comprises a harness buckle. The coupling device 10 is hinged into the slot. When placed in this configuration, the first coupling device 10 is ready for receiving the tongue of a harness of a child safety seat. The first coupling device 10 is, therefore, in the active position. The second coupling device 20 (not visible in Fig. 3 a) is stored in the storage system 110. The second coupling device 20 is therefore in the inactive position. The storage system 110 is covered by a lid 115. The lid 115, in the closed position, is used as a lock for the first coupling device 10 in the active position. That is, the closed lid 115 closes off the first 80 and second 85 slot so that the first coupling device 10 is locked in the first slot 80. In particular, side movement of the coupling device 10, that is, movement out of the first slot 80, is not possible. Fig. 3b shows the anchoring system 30 with an open lid 115. In this configuration, the second coupling device 20 stored in the storage system 110 is visible. Furthermore, the first slot 80 and the second slot 85 are not blocked any more by the lid 115. That is, the first coupling device 10 may be transferred along the first slot 80 of the anchoring means out of its active position. This allows the first coupling device 10 to be removed from the first slot 80. Fig. 3c shows the anchoring system 30 in a configuration after changing the active and inactive positions of the first coupling device 10 and second coupling device 20. The first coupling device 10 is stored in the storage system 110. The first coupling device 10 is therefore in the inactive position. The second coupling device 20 is located into the second slot 85. The second coupling device is, thus, in the active position. The coupling device 20 shown in Fig. 3c is a safety belt clip. Fig. 3d shows the anchoring system 30 with the second coupling device 20 in the active position. The lid 115 of the storage system 110 is closed. The first coupling device 10 stored in the storage system 110 is, therefore, not visible. The closed lid 115 serves as a lock for the second coupling device 20 inserted in the second slot 85. That is, the closed lid 115 blocks the second coupling device 20 from being removed or loosened from the second slot 85.
Figures 3a-3d show a sequence of steps that may be performed when converting a child safety seat used with the integral harness into a child safety seat used with the safety belt of a vehicle. The anchoring system 30 may be installed in the seating portion of a child safety seat. For converting the child safety seat, a user first opens the closed lid 115 (sequence from Fig. 3a to Fig. 3b). The active first coupling device 10 may then be removed from the first slot 80. This may be done by removing the first coupling device 10 from the anchoring means by sliding it out of the first slot 80. Furthermore, the inactive second coupling device 20 is taken out of the storage system 110. The first coupling device 10 is then placed into the storage system 110. The first coupling device 10 has, thus, been transferred out of the first slot 80 of the anchoring means from the active position to the inactive position. The second coupling device 20 is located into the second slot 85 (as shown in Fig. 3b). This may be accomplished by inserting the second coupling device 20 into the second slot 85, and sliding it into the second slot 85 of the anchoring means. Finally, the lid 115 is closed. This holds the second coupling device 20 in the
2018256574 31 Oct 2018 second slot 85. Side movement of the second coupling device 20 is prevented. The second coupling device 20 is now in the active position and is secured in the anchoring system 30. The conversion of the child safety seat that is used with the safety belt of a vehicle into a child safety seat used with the integral harness may be done by performing the steps described above in reverse order, i.e., with the first and second coupling devices interchanged. The first 10 and second 20 coupling devices are, thus, each transferrable along the anchoring means 80, 85 between the respective active position and the respective inactive position.
It is also shown in Figs. 3a-3d that the anchoring means, e.g., slots 80, 85 are spaced apart from one another. The arrangement of the slots 80, 85 is such that when the anchoring system 30 is installed in the seating portion of the child safety seat, the active first coupling device is positioned closer to the backrest of the child safety seat than the active second coupling device. This arrangement of the slots 80, 85 takes into account the different sizes and ages of the children. While the configuration with an active first coupling device 10 is used for smaller children, the configuration with the second coupling device 20 is used for older children. The placement of the second coupling device 20 further from the backrest of the child safety seat than the first coupling device 10 gives older children sufficient space on the seating portion of the child safety seat.
Figures 4a and 4b show a third embodiment of the anchoring system 30 in accordance with the invention. The anchoring system 30 shown in Figs. 4a and 4b differs from the anchoring system of the second embodiment shown in Figs. 1 and 3a-3d in that the anchoring means 80, 85 comprises a rail system with slots that act as rails. The first coupling device 10 is anchored in the first rail 80. The second coupling device 20 is anchored in the second rail 85. The movement of the first 10 and second 20 coupling devices is restricted to the respective rails 80 and 85. The first 10 and second 20 coupling devices are anchored to the respective rails 80 and 85 with the help of respective socket plates 70 and 75. For bringing either of the coupling devices 10, 20 into the active position, the respective coupling device 10 or 20 is moved from the storage system 110 along the slot / rail 80 or 85 until it reaches a position outside the storage system 110. For this, the storage system comprises a ramp shaped exit portion 116. The coupling device 10 or 20 is then in the active position. The other coupling device 10 or 20 is brought into the inactive position as follows, ft is moved along the slot / rail 80 or 85 into the storage system 110. The shown storage system 110 has the form of a pocket. The coupling of the coupling device 10 or 20 to the slot / rail 80 or 85 is such that it is possible for ft to be rotated, tilted or turned by 90 degrees around an axis parallel to the rail 80 or 85. That is, the anchoring system 30 is configured so that either of the coupling devices may be rotated from an upright position into a horizontal position. This enables the coupling devices 10 or 20 to be stowed in the storage system 110. The first 10 and second 20 coupling device of the third embodiment may not be disconnected from the anchoring system 30. Because of this, the risk that either of the coupling devices being lost or misplaced
2018256574 31 Oct 2018 is greatly reduced. The lid 115 may be closed. It serves as a lock for the coupling devices 10 or 20 in their active positions the same as described above in relation to Figs. 3a-3d. The arrangement of the slots / rails 80 and 85 may be the same as that described above in relation to Figs. 3a-3d, i.e., they may be separated by a distance for taking into account the different sizes and ages of the children.
In the embodiment shown in Figs. 4a and 4b and described above the first 10 and second 20 coupling devices are anchored to the respective rails 80 and 85 with the help of respective socket plates 70 and 75. In accordance with the invention, it is, however, also possible that the movement of the socket plates 70, 75 are restricted to a horizontal plane. If the movement of the socket plates 70, 75 is restricted to a horizontal plane the socket plates 70, 75 themselves do not need to be guided over the ramp shaped exit portion 116 of the storage system 110. This has the advantage that the transfer of either of the coupling devices 10, 20 into the active position or back into the inactive position is smoother. The mechanism that restricts the movement of the socket plates 70, 75 to the horizontal plane may be part of the rail system 80, 85.
Figures 5a and 5b show a fourth embodiment of the anchoring system 30 of the invention. The embodiment shown in Figs. 5a and 5b differs from the third embodiment described with respect to Figs. 4a and 4b in that the anchoring system 30 further comprises a coupling mechanism 34. The coupling mechanism comprises a belt 35 and a reverse wheel 36. The belt 35 is located around the wheel 36. One end portion of the belt 35 is linked to the first coupling device 10. A second end portion of the belt 35 is linked to the second coupling device 20. The linkage of the first 10 and second 20 coupling device enables simultaneous movement of both coupling devices. The movement of one coupling device (10 or 20) along the respective slot / rail 80, 85 causes the other coupling device (10 or 20) to move along the respective slot / rail 80, 85 in the reverse direction. Figure 5a shows the first coupling device in the active position. In Fig. 5b it is shown that the movement of the second coupling device 20 along the slot / rail 85 out of the storage system has caused the first coupling device 10 to be moved inside the storage system. This prevents that coupling devices 10 or 20 are at the same time both in the active or both in the inactive position. When this coupling mechanism is used, it is particularly advantageous if the movement of the socket plates of the coupling devices 10, 20 is restricted to a horizontal plane as described previously. Other arrangements that will move each coupling device 10 for 20 simultaneously would be considered to be within the scope of this invention.
Figures 6a, 6b and 6c show a variant of the anchoring means / rail system and the storage system of the invention. This variant differs from the embodiment described with respect to Figs. 4a and 4b in that only one rail 80 is used. In addition, the storage system comprises two pockets 117, 118. The first pocket 117 is adapted to store the first coupling device 10, the second pocket 118 is adapted to store the second coupling device 20. Figure 6a shows the first coupling device 10 in its active position (indicated
2018256574 31 Oct 2018 by the dashed line). The second coupling device 20 is stored in the second pocket 118. Thus, the second coupling device 20 is in its inactive position. Figure 6b shows the second coupling device 20 in its active position. The first coupling device 10 is stored in the first pocket 117. Thus, the first coupling device 10 is in its inactive position. In Fig. 6c both coupling devices 10, 20 are stored in the respective pockets 117, 118. Thus, both coupling devices are in the inactive positions. The transfer of the coupling devices 10, 20 between the active and the inactive position is similar to that described with regard to Figs. 4a and 4b. That is, when in the inactive position, the coupling device is guided along the rail 80 out of the respective pocket until it reaches the active position (as indicated by the dashed lines in Figs. 6a, 6b, 6c). The use of two pockets 117, 118 has the advantage that both coupling devices 10, 20 may be stored at the same time. Therefore, when the child safety seat is used as a highback booster seat for older children, both coupling devices 10, 20 may be securely stowed without the risk that one of them gets lost.
Figures 6d and 6e show the variant of the rail and storage system described before with respect to Figs. 6a, 6b and 6c, i.e., employing one rail 80 and two pockets 117, 118, additionally including a coupling mechanism 34. The coupling mechanism 34 comprises a pull element 35 such as a belt, wire or chain. In Figs. 6d and 6e it is shown that the first 10 and second 20 coupling device are coupled to one another by the coupling mechanism 34, 35. Specifically, in Fig. 6d the first coupling device 10 is in its active position (indicated by the dashed line). The second coupling device 20 is stored in the second pocket 118. Thus, the second coupling device 20 is in its inactive position. In Fig. 6e the positions of the first 10 and second 20 coupling device are interchanged. For the variant with one rail 80 the use of the coupling mechanism 34 is particularly advantageous. Since there is no stop on the rail which places the coupling devices in the correct active position, the coupling mechanism 34 assists a user to find the correct active position automatically. Furthermore, the coupling mechanism 34 may be realized by simple components such as a belt, a wire or a chain. When converting the child safety seat used with the integral harness into a child safety seat used with the safety belt of the vehicle both the first and the second coupling elements 10, 20 move in the same direction when either are moved left or right. That is, no looping back of the belt, wire or chain around a wheel is necessary, unlike the coupling mechanism 34 described with regard to Figs. 5a and 5b. Furthermore, owing to the coupling mechanism 34, movement of one coupling device causes the other coupling device to move. Therefore, the conversion of the child safety seat 15 is quicker and easier.
Figures 7a, 7b and 7c show another variant of the anchoring means / rail system and the storage system of the invention. This variant differs from the variant described with regard to Figs. 6a, 6b and 6c in that the rail system comprises two rails 80 and 85. The first rail 80 is adapted to anchor the first coupling device 10. The second rail 85 is adapted to anchor the second coupling device 20. The variant of Figs. 7a, 7b and 7c still comprises a storage system with two pockets 117, 118. That is, a first pocket 117
2018256574 31 Oct 2018 adapted to store the first coupling device 10; a second pocket 118 adapted to store the second coupling device 20. Figure 7a shows the first coupling device 10 in its active position (indicated by the dashed line). The active position is further indicated in that the first coupling device 10 is placed at the stop of the first rail 80. The second coupling device 20 is stored in the second pocket 118. Thus, the second coupling device 20 is in its inactive position. Figure 7b shows the second coupling device 20 in its active position. The first coupling device 10 is stored in the first pocket 117. Thus, the first coupling device 10 is in its inactive position. In Fig. 7c both coupling devices 10, 20 are stored in the respective pockets 117, 118. Thus, both coupling devices are in the inactive positions. The transfer of the coupling devices 10, 20 between the active and the inactive position is similar to that described with regard to Figs. 4a and 4b. That is, when in the inactive position, the coupling device 10, 20 is guided along the respective rail 80, 85 out of the respective pocket 117, 118 until it reaches the respective stop. It has then reached the respective active position (as indicated by the dashed lines in Figs. 7a, 7b, 7c). In addition to the advantages mentioned with regard to the variant of Figs. 6a, 6b and 6c, the use of two rails has the advantage that the active position is clearly indicated to the user by the stops of the rails. That is, the correct active position is reached once a coupling device is pushed against the stop of the respective rail. Further, the active position is more stable, since the movement of the coupling device is more restricted. Finally, the arrangement of the rails 80 and 85 may be the same as that described above in relation to Figs. 3a-3d and Figs. 4a and 4b, i.e., they may be separated by a distance taking into account the different sizes and ages of the children.
Figures 7d and 7e show the variant of the rail and storage system described before with respect to Figs. 7a, 7b and 7c, i.e., employing two rails 80, 85 and two pockets 117, 118, additionally including a coupling mechanism 34. As in the variant of Figs. 6d and 6e, the coupling mechanism 34 comprises a pull element 35 such as a belt, wire or chain. In Figs. 7d and 7e it is shown that the first 10 and second 20 coupling device are coupled to one another by the coupling mechanism 34, 35. In Fig. 7d the first coupling device 10 is in its active position (indicated by the dashed line). The second coupling device 20 is stored in the second pocket 118. Thus, the second coupling device 20 is in its inactive position. In Fig. 7e the positions of the first 10 and second 20 coupling device are interchanged. The advantages of the coupling mechanism of the variant of Figs. 7d and 7e are the same as those described above in relation to the variant of Figs. 6d and 6e.
Figures 8a and 8b show a further variant of the anchoring means / rail system and the storage system of the invention. In this variant, the rail system comprises a Y-shaped rail. In other words, the rail system comprises a forked junction where the single rail forks into a pair of rails. At the junction, a single common rail splits up into a first rail 80 and a second rail 85. The single common rail is adapted to receive the first coupling device 10 and the second coupling device 20. Advantageously, the first rail 80 is adapted to receive and anchor the first coupling device 10; the second rail 85 is adapted to receive and
2018256574 31 Oct 2018 anchor the second coupling device 20. The storage system 110 according to this variant comprises one pocket. The storage system 110 may be adapted to store either of the first 10 or second 20 coupling devices. Figure 8a shows the first coupling device 10 in its active position (indicated by the dashed line). The active position is further indicated in that the first coupling device 10 is placed at the stop of the first rail 80. The second coupling device 20 is stored in the storage system 110. Thus, the second coupling device 20 is in its inactive position. Figure 8b shows the second coupling device 20 in its active position. The first coupling device 10 is stored in the storage system 110. Thus, the first coupling device 10 is in its inactive position. The transfer of the coupling devices 10, 20 between the active and the inactive position is accomplished as follows. The coupling device that is stored in the storage system 110 is guided out of the storage system 110 along the rail system. At the fork junction, the coupling device 10, 20 is guided into the respective rail 80, 85 until it reaches the stop of the respective rail 80, 85. If the rails 80, 85 are configured such that the first coupling device 10 may only be received by the first rail 80, and the second coupling device 20 may only be received by the second rail 85, the risk for misplacing the coupling devices is reduced. Furthermore, according to this variant, since only one single common rail leads into the storage system 110, storage place for either the first 10 or the second 20 coupling device may be given. In this case, the user is forced to use at least one of the coupling devices. This has the advantage that the user is reminded to use one of the coupling devices. The further advantages of this variant are the same as those of the variants employing two separate rails described above in relation to Figs. 4a and 4b and Figs. 7a, 7b and 7c. Finally, the arrangement of the rails 80 and 85 may be the same as that described above in relation to Figs. 3a-3d and Figs. 4a and 4b, i.e., they may be separated by a distance for taking into account the different sizes and ages of the children.
Figures 8c and 8d show the variant of the rail and storage system described before with respect to Figs. 8a and 8b, i.e., employing a Y-shaped rail with a first 80 and a second 85 rail and one pocket, additionally including a coupling mechanism 34. The coupling mechanism 34 corresponds to that described in relation to Figs. 5a and 5b. That is, the coupling mechanism 34 comprises a belt 35 and a wheel 36. As shown in Figs. 8c and 8d, one end of the belt 35 is coupled to the first coupling device 10, the other end of the belt 35 is coupled to the second coupling device 20. By this, the first 10 and second 20 coupling device are coupled to one another. The wheel 36 ensures that the movement of one coupling device in one direction causes the other coupling device to move in the other direction. This opposite movement is necessary since one single pocket is used. In Fig. 8c the first coupling device 10 is in its active position (indicated by the dashed line). The second coupling device 20 is stored in the pocket of the storage system 110. Thus, the second coupling device 20 is in its inactive position. In Fig. 8d the positions of the first 10 and second 20 coupling device are interchanged. The advantages of the coupling mechanism of the variant of Figs. 8c and 8d are the same as those described above in relation to Figs. 5a and 5b.
2018256574 31 Oct 2018
Figures 9a, 9b and 9c show a further variant of the anchoring means / rail system and the storage system of the invention. In this variant, the rail system comprises a Y-shaped rail. With regard to the variant shown in Figs. 8a and 8b, the Y-shaped rail is reversed. That is, there is one single common rail adapted to anchor the first 10 and second 20 coupling device in the active position. There are, however, two 5 rails, each one for receiving, respectively, the first 10 or the second 20 coupling device in the storage system 110. Preferably, the first rail is adapted to receive the first coupling device 10; the second rail is adapted to receive the second coupling device 20. The storage system 110 according to this variant comprises a first pocket 117 and a second pocket 118. The first pocket 117 is adapted to store the first coupling device 10; the second pocket 118 is adapted to store the second coupling device 20. Instead of 10 two pockets, the storage system 110 may comprise a single pocket adapted to store both the first 10 and second 20 coupling device at the same time. Figure 9a shows the first coupling device 10 in its active position (indicated by the dashed line). The active position is further indicated in that the first coupling device 10 is placed at the stop of the single common rail. The second coupling device 20 is stored in the second pocket 118 of the storage system 110. Thus, the second coupling device 20 is in its inactive 15 position. Figure 9b shows the second coupling device 20 in its active position. The second coupling device 20 is placed at the stop of the single common rail. The first coupling device 10 is stored in the first pocket 117 of the storage system 110. Thus, the first coupling device 10 is in its inactive position. In Fig. 9c both coupling devices 10, 20 are stored in the respective pockets 117, 118. Both coupling devices 10, 20 are, thus, in their respective inactive positions.
The transfer of the coupling devices 10, 20 between the active and the inactive position is accomplished as follows. It is assumed that the first coupling device 10 is in its active position and the second coupling device 20 is in its inactive position, as shown in Fig. 9a. The first coupling device is first transferred along the single common rail of the Y-shaped rail until it reaches the fork junction. At the fork junction the first coupling device 10 is further guided along the rail which leads into the first pocket 25 117. It is preferable that the first coupling device 10 may only be received by the first rail, and the second coupling device 20 may only be received by the second rail of the Y-shaped rail. This facilitates the storing of the coupling devices in the respective pockets. The second coupling device 20 that is stored in the second pocket 118 is guided out of the second pocket 118 along the respective rail of the rail system. At the fork junction, the second coupling device 20 is guided into the single common rail 30 until it reaches the stop. This configuration is shown in Fig. 9b. The case in which the second coupling device is in the active position while the first coupling device is in its inactive position can be treated analogously. Since the storage 10 system comprises two pockets 117, 118, both coupling devices 10, 20 may be stored at the same time, as shown in Fig. 9c. The advantages of providing two pockets are the same as described above in relation to the variants of Figs. 6a, 6b, 6c and Figs. 7a, 7b, 7c.
Figs. 6-9 show variants of the anchoring system / rail system and the storage system which particularly
2018256574 31 Oct 2018 relate to the number and arrangement of rails, and to the number and arrangement of the pockets. It is, therefore, understood that any of the variants of Figs. 6-9 can be used in any of the embodiments described in relation to Figs. 3, 4 and 5, and that all particulars and details which have been described in relation to Figs. 3, 4 and 5 but which have not further been addressed with regard to Figs. 6-9 are fully compatible with and may be used with variants of Figs. 6-9, as well. The embodiments and variants previously described may be installed or integrated in the seating portion of a child safety seat.
An embodiment according to the second aspect of the invention is described in relation to Figs. 10a and 10b. Figure 10a shows two conventional buckle tongues 12 adapted to engage with a coupling device of a harness system of a child safety seat. The coupling device is preferably a harness buckle. The buckle tongues 12 are attached to the two-sttap safety belt 15 of the harness. The coupling device is not shown in Fig. 10a. When the tongues 12 are engaged with the coupling device, the harness is securely fixed. For this, the coupling device may comprise a slot for receiving the tongues 12. For releasing the tongues 12 from the coupling device, the coupling device may comprise a release button. Upon activation, e.g., pressing of the release button, the tongues 12 may be removed from the coupling device.
Figure 10b shows an insertion tongue 21 according to the invention. The insertion tongue 21 comprises a coupling element 23 and an engaging element 22. The coupling element 23 fits into the slot of the coupling device, such as the harness buckle. The coupling element 23 may be formed as a latch. The coupling element 23 of the insertion tongue 21 is configured such that locking and/or release of the insertion tongue 21 in the coupling device can be accomplished in the same manner as that of the tongues 12. The engaging element 22 is adapted to receive the lap portion of a safety belt of a vehicle. As shown in Fig. 10b, the engaging element 22 may be formed as a hook. The insertion tongue 21 of the invention is adapted to be inserted in the coupling device of a child safety seat. For converting the child safety seat when used with the harness system into a child safety seat to be used with the safety belt of the vehicle, the coupling element 23 is inserted into the slot of the coupling device. The insertion tongue 21 inserted in the coupling device operates as a safety belt clip. No removal of the coupling device is necessary. The conversion is fast and easy. For removing the insertion tongue 21 from the coupling device, the release button of the coupling device is pressed. When the coupling device is used with the integral harness system, the insertion tongue 21 may be attached close to the coupling device. The insertion tongue 21 may be attached to the child safety seat. The insertion tongue 21 may be attached by a wire or a flexible element and/or it may be stored in a storage compartment comprised by the child safety seat. This avoids that the insertion tongue 21 gets lost.
An embodiment in accordance with the third aspect of the invention is shown in Figs. Ila and b. Fig. Ila shows a combination coupling device 16. The combination coupling device 16 comprises a coupling device 11 and a fixation element 14. Further shown are a tongue of a harness system and two2018256574 31 Oct 2018 strap safety belts 15 of the harness. The fixation element 14 is adapted to connect the combination coupling device 16 to the seating portion of child safety seat. The fixation element 14 may comprise a socket plate. Fixation element 14 may also be only a strap that is attached to the seating portion. The coupling device 11 comprises an engaging element 111 and a positioning element 112. The engaging 5 element shown in Fig. Ila is a harness buckle including a hook 113. The harness buckle further comprises a slot. The tongues 12 of the harness system may be inserted in the slot of the harness buckle. The hook 113 is configured to receive and to engage with the lap portion of a vehicle seat. The hook 113 forms the safety belt clip part of the combination coupling device 16. In Fig. Ila the combination coupling device 16 is used with the integral harness system of the child safety seat. The positioning 10 element 112 ensures that the engaging element 111 is placed at a proper position for receiving the tongue 12 of the harness. The positioning element 112 may comprise a strap, and/or a flexible or rigid element which is adapted to position the engaging element 111 at a distance from the seating portion of the child safety seat 100. Advantageously, the length of the positioning element 112 is adjustable. For instance, the length of the strap and/or that of the flexible or rigid element may be adjusted.
In Fig. 1 lb the combination coupling device 16 already described with respect to Fig. 1 la is shown with a safety belt 25 engaged in the hook 113 of the engaging element 111. The tongue 12 of the harness is not used in this configuration. In this configuration, the combination coupling device 16 operates as a safety belt clip. Preferably, the safety belt clip is integrated in the release button of the harness buckle. 20 Preferably, when used as a safety belt clip, the slot of the harness buckle can be covered by a lid (not shown). This protects the open slot from dirt.
By using the combination coupling device 16 in accordance with the invention, the useful life of the child safety seat 100 can be extended while the child gets older, without the need of storing any replacement parts that might otherwise be misplaced or lost over time. The functionality of the harness 25 buckle and of the safety belt clip are integrated in the combination coupling device 16. Therefore, the combination coupling device 16 does not need to be removed or exchanged when converting the child safety seat from the configuration using the integral harness to the configuration using the safety belt of the vehicle. When converting into the configuration using the safety belt of the vehicle, only the harness and the buckle tongues need to be stowed in a respective storing compartment. A child safety seat 30 comprising the combination coupling device 16 may be configured so that the combination coupling device 16 can be adjusted by linear movement or rotation. This allows for adjustable positioning of the combination coupling device 16 adapted to the size and age of the occupant of the child safety seat.
