Description

The invention relates to a child seat with an adjusting mechanism for adjusting the height of the headrest of the child seat. In particular, the invention relates to a combination child seat with an anti-misuse mechanism which prevents a user from using the child seat too long in the integral mode and from using the child seat too early in the non-integral mode.

Smaller children, such as babies or toddlers, are restrained in their safety seat mounted on an occupant seat of a vehicle with a special restraint device, such as an integral belt system. For this age group, a safety seat with a 3-point or 5-point belt using a belt buckle as a connecting device is the safest way to travel. The 3-point or 5-point belt of the safety seat secures the child's shoulders and hips firmly in the seat. To secure the child properly with the 3-point or 5-point belt, it is important that the shoulder straps of the The belt must be properly guided over the child's shoulders so that the child's body is efficiently restrained and braked in the event of a frontal collision. In addition, to protect the child's head, the headrest of the child seat must be correctly adjusted so that the forces from the impact are diverted from the head.

In order to facilitate the adjustment of the shoulder straps and the headrest according to the size and age of the child, some of the known child seats have an adjustment mechanism that connects the belt and the headrest. As a result, the adjustment of the headrest effects the correct adjustment of the belt and vice versa.

Older children can use the 3-point adult seat belt with a highback booster seat as it positions the 3-point adult seat belt correctly over the child's body. Such child seats also have a height-adjustable headrest.

From the above, child seats can be used either with an integral belt system or in conjunction with the seat belts of a vehicle to restrain a child on the child seat. Child seats that use means directly connected to the vehicle, such as adult seat belts, to restrain the child, fall into the so-called non-integral class.

There are also so-called combination child seats or so-called group 1/2/3 child seats. Combination child seats make it possible to combine different safety systems for smaller children and for older children on one seat. When used for a smaller child, the integral belt system of the combination child seat is used to secure the child. This is the so-called integral mode. The integral harness can be either a 3-point or a 5-point harness. The 3-point belt includes two shoulder straps. At one end portion of each shoulder strap, a tongue is connected, which is designed to engage in a belt buckle. The other ends of each shoulder strap are connected to the combination child seat. The 5-point harness also includes two straps. One end of each strap is connected to the seat base of the combination child seat. A locking tongue is slidably connected to each band. The locking tongues are inserted into the belt buckle to secure the child. The section of the strap running from the seat base to the tongue is passed over the child's hip / thigh. The portion of the straps running from the tongue to the backrest of the combination child seat is passed over the child's shoulders. As the child gets older, they are secured in the combination child seat using the vehicle's seat belt. Then the integral belt system can be stowed away. This is the so-called non-integral mode. The combination child seat can be used over a wider age range of the child.

The integral mode starts at around 1 year of age and ends at around 4 years or more. The non-integral mode starts at around 3 years of age and ends at 12 years of age. Thus there is an overlap area between about 3 and 4 years in which the child seat can be used either in the integral mode or in the non-integral mode. Because of this, there are several potential sources of misuse. The child seat may be used in integral mode for too long. Likewise, the change from the integral mode to the non-integral mode could have been carried out too early. Performing the change from the integral mode to the non-integral mode outside the above-mentioned overlap range of about 3 to 4 years dramatically increases the risk of serious injury to a child in a vehicle accident if the child seat is not used in the appropriate mode.

In addition, the conversion of known combination child seats from the integral mode to the non-integral mode is usually very cumbersome. As mentioned above, when using the combination child seat with the integral belt system, ie in the integral mode, the latter is usually connected to the headrest. In the integral mode, known combination seats comprise an adjuster on the back of the seat for adjusting the Headrest and the belt. For the transfer to the non-integral mode, a removal of the belt is necessary in many of the known combination child seats. Only when this has been done can the headrest be raised further. However, the headrest must be raised further by means of a second adjuster. For this reason, known child seats use two separate adjusters to adjust the height of the headrest, depending on the integral or non-integral mode in which the seat is used. Not only does this make the switch cumbersome, but it also poses a risk, especially in cases where users need to reattach the integral harness.

The EP 2 474 440 A2 is aimed at a child's vehicle seat with an adjustable belt system. The belt system has a pair of safety straps, each with a rear section on the rear of the child vehicle seat, and a shoulder strap section on the forward-facing side of the child vehicle seat. A manifold is located on the rear of the child vehicle seat and has a fixed upper guide, a fixed lower guide spaced below the upper guide, and a slider movable vertically therebetween. The safety straps are passed through the slide. The slide is vertically adjustable between a raised position and a lowered position and determines the height of the shoulder strap sections.

The WO 2015/025434 A1 describes a child seat that can attach a child safety belt. The child seat includes: the child seat belt having a loop portion formed at one end thereof; an attachment opening having a through hole formed therein through which an end of the child safety belt is caused to pass; and a rod-shaped attachment rod. After the child safety belt has passed through the through hole in the fastening opening, the fastening rod is inserted into the loop portion, whereby the child safety belt is prevented from loosening.

Therefore, it is an object of the present invention to provide a child seat with improved ease of use, which allows easier and faster changeover between integral mode and non-integral mode, and with an anti-misuse mechanism, which prevents excessive use of the non-integral mode and / or the prevents the non-integral mode from being used too early. This object is achieved by the child seat according to claim 1 and by the child seat according to claim 10. Further advantageous embodiments of the present invention are specified in the dependent claims.

According to a first aspect of the invention, a child seat with a seat shell, a headrest, a guide component slidably connected to the seat shell for guiding a strap of an integral belt system of the child seat and an adjustment mechanism for adjusting the height of the headrest, comprising a connecting element, is provided. The connector is configured to be placed in a first configuration and a second configuration. When placed in the first configuration, the connecting element connects the headrest to the guide component to allow movement of the headrest together with the guide component relative to the seat pan. When placed in the second configuration, the connecting element connects the seat pan to the guide component to prevent movement of the guide component relative to the seat pan and to allow movement of the headrest relative to the seat pan.

Given the two configurations in which the connecting element can be placed, a height adjustment of the headrest of the child seat can be achieved when used together with the integral belt system or with a safety belt of a vehicle for securing a child on the child seat. The child seat can be used in integral mode or in non-integral mode. The integral belt system does not have to be removed even if the child seat is used in the non-integral mode. The integral mode of the child seat is defined by the use of the integral belt system to secure a child on the child seat. The non-integral mode is defined by the use of a vehicle's seat belt to secure the child in the child seat. The adjustment mechanism according to the invention has the advantage that only the connecting element has to be actuated to release the guide component for guiding the straps of the integral belt system from the headrest when the headrest has reached a height that corresponds to an age in which the non-integral mode becomes imperative. Preferably the first configuration is used during the integral mode. Preferably the second configuration is used during the non-integral mode. The guide component is advantageously a belt slide which is designed to guide the shoulder straps of the integral belt system. In the first configuration, the adjustment of the headrest due to the connection of the headrest by the connecting element to the guide component causes the shoulder straps of the integral belt to be correctly positioned, and vice versa. When the connecting element is placed in the second configuration, the guide component for guiding the shoulder straps is the integral belt system decoupled from the headrest. The guide component is prevented from moving relative to the seat shell, while movement of the headrest relative to the seat shell is possible. That is, when placed in the second configuration, the connecting element couples the seat shell to the guide component so that the guide component remains in a fixed position when the headrest is moved. By securing the guide component in the second configuration of the connector, the integral belt can remain attached to the child seat. By decoupling the guide component from the headrest, the movement of the headrest is no longer related to the guide component. The integral belt therefore does not prevent the headrest from being adjusted in a non-integral mode. As a result, the height of the headrest can still be adjusted in the same way as in the first configuration. This has the advantage that only one element has to be actuated for the height adjustment, regardless of the configuration in which the child seat is used. A second advantage is that the integral belt can remain on the child seat; it does not have to be removed when the child seat is used in the non-integral mode. Since the integral belt does not have to be removed, misuse by the user is prevented, in particular when a switch is made from the non-integral mode back to the integral mode.

The seat shell advantageously comprises a seat section. The seat section is configured to receive the floor and part of the child's legs.

Preferably, the child seat is configured to allow the headrest to be engaged with the seat pan at a height that extends from a lowest position to an intermediate position that is further away from the seat portion than the lowest position when the Fastener is in the first configuration. It is further preferred that the child seat is configured so that the headrest can come into engagement with the seat pan at a height ranging from the intermediate position to a highest position that is further away from the seat portion than the intermediate position the connector is in the second configuration. The area between the lowest position and the intermediate position defines the adjustment range of the headrest in the first configuration. The lowest position defines the lowest possible position for the headrest. This lowest position is preferably selected so that the headrest is suitable for children aged 1 year. The intermediate position defines the highest possible position of the headrest when the connecting element is in the first configuration, preferably in the integral mode. In other words, above the intermediate position, the guide component for the straps of the integral belt system is decoupled from the movement of the headrest. Another lifting of the guide component, e.g. B. with the outlets of the shoulder straps of the integral belt system, beyond the intermediate position is not possible. In addition, the headrest must not be placed in positions higher than the intermediate position as long as the connecting element is placed in the first configuration. This means that with older children sitting in the child seat, it may not be possible to guide the straps of the integral belt system correctly over the child's shoulders or to adjust the height of the headrest correctly. As a result, a user attempting to use the integral harness system for older children will realize that this is hardly possible. As a result, the child seat is prevented from being used in integral mode for too long.

It is advantageous if this intermediate position is chosen so that the headrest is suitable for children aged 4 and over. The distance between the lowest position and the intermediate position is preferably between 9 cm and 13 cm, advantageously between 10.5 cm and 11.1 cm, the most preferred value being 11.1 cm.

The highest position defines the highest possible position of the headrest when the connecting element is in the second configuration, preferably in the non-integral mode. The highest position is preferably the highest possible position in which the headrest can be placed. It is advantageous if this highest position is selected so that the headrest is suitable for children aged 12 and over. The distance between the intermediate position and the highest position is preferably between 12 cm and 16 cm, advantageously between 13.5 cm and 14.5 cm, the most preferred value being 14.2 cm.

The adjustment range can be taken from anthropometric data. In the integral mode, the shoulder height should be variable between 28 cm and 39.1 cm when measured from the seat section. Since the guide component is preferably positioned so that the shoulder straps of the integral belt are led out of the guide component essentially horizontally over the child's shoulders, the guide component is designed to be measured in the range between 27 cm, measured from the seat section, to 40 cm from the seat section, advantageously between 28 cm, measured from the seat section, to 39.5 cm, measured from the seat section, to be movable. The lowest position is preferably between 27 cm and 28 cm positioned from the seat section. The intermediate position is preferably positioned between 39 cm and 39.5 cm from the seat section. In the non-integral mode, the shoulder height should be variable between 39.1 cm and 53.3 cm, measured from the seat section.

Since the lower edge of the headrest is correctly positioned when it almost touches the shoulders of the child sitting in the child seat, the headrest is designed to be in the range between 27 cm, measured from the seat section, to 55 cm, measured from the seat section, advantageously between 28 cm, measured from the seat section, to 53.5 cm, measured from the seat section, to be moved. The lowest position is preferably positioned between 27 cm and 28 cm from the seat section. The highest position is preferably positioned between 53.0 cm and 53.5 cm from the seat section.

The connecting element is advantageously configured so that a change from the first to the second configuration is only possible when the headrest is in the intermediate position. This means that a change from the first to the second configuration is only possible if the headrest is placed in the highest possible position in the first configuration. The advantage is that it prevents misuse and prevents large children from being secured with the integral belt system for too long. The user is thus forced to secure the child with the vehicle's seat belt when the headrest has to be adjusted to a height that goes beyond the intermediate position.

In the non-integral mode, the shoulder straps of the integral belt can advantageously be stowed or hidden behind a backrest cover of the child seat. Hiding the shoulder straps behind the cover increases the comfort of the child sitting on the seat when the seat is used in the non-integral mode, as there is no direct contact of the child's back with the shoulder straps.

When placed in the first configuration, the connecting element advantageously further couples the headrest to the guide component in such a way that the distance between the headrest and the guide component remains constant during their movement. The distance is preferably selected such that the guide component is positioned on a lower edge of the headrest. As a result, the shoulder straps of the belt system are positioned such that they can run essentially parallel over the shoulders of the child sitting on the child seat. This is the correct position for the shoulder straps. Since the distance does not change as long as the connecting element is in the first configuration, the adjustment of the headrest causes an automatic adjustment of the integral belt and vice versa. The adjustment of the integral belt takes place in such a way that the guide components and thus the shoulder straps that pass through them are at the correct height. Advantageously, the adjustment mechanism further comprises a locking mechanism which is designed to bring the headrest into engagement with the seat shell at different heights from the seat section. The locking mechanism has the advantage of attaching the headrest at different heights. This allows the headrest to be adjusted depending on the size and age of the child. The locking mechanism is preferably designed to enable the headrest to be displaced gradually. Alternatively, however, a continuous displacement of the headrest can also be advantageous.

Advantageously, the locking mechanism of the adjustment mechanism further comprises an actuator which can be actuated to move the headrest from the lowest position to the intermediate position when the connecting element is in the first configuration, and from the intermediate position to the highest position when the Fastener is in the second configuration. The actuator, which can be actuated both in the first configuration and in the second configuration for moving the headrest, has the advantage that the height adjustment of the headrest can be carried out by a single operating element. The operation of the same actuator is sufficient to adjust the height of the headrest in the first configuration and in the second configuration of the connecting element. It is preferred that the actuator is arranged on top of the headrest. This allows the headrest to be adjusted even when the seat is installed in a vehicle or even when the child is placed on the child seat.

Preferably, the locking mechanism comprises a rack attached to the seat pan and a locking part, the locking mechanism being configured such that the locking part is received by the rack when the headrest is engaged with the seat pan. The rack can either be formed in one piece with the seat shell, or it can also be a separate component. The toothed rack and the locking part provide a simple mechanism which allows the headrest to be displaced gradually. It is also preferred if the locking mechanism is configured such that the locking part disengages from the rack when the actuator is in operation. This ensures that the adjustment of the height of the headrest through Operation can only be carried out on the actuator. That is, by operating the actuator, the headrest is released from engagement with the rack, which allows the headrest to be moved up or down on the seat pan.

Advantageously, the seat shell further comprises a backrest section, the guide component being displaceable along the backrest section when the connecting element is placed in the first configuration. This, preferably, allows adjustment of the integral belt system when the child seat is used in the integral mode. Preferably, the backrest portion of the seat pan has a backrest opening, the guide component and the connecting element being slidably mounted in the backrest opening when the connecting element is placed in the first configuration. The backrest opening advantageously provides a guide rail for the guide component. Furthermore, it is advantageous if the backrest opening also provides a guide rail for the connecting element. Preferably, the backrest opening of the seat shell is dimensioned such that the headrest is allowed to move from the lowest position to the intermediate position.

Advantageously, the headrest has a headrest opening which is designed to receive the guide component when the connecting element is in the second configuration, and wherein the headrest opening is dimensioned so that it allows the headrest to move from the intermediate position to the highest position move. The headrest opening allows adjustment of the headrest as soon as the connecting element is placed in the second configuration, even if the guide component is attached in the intermediate position.

The connecting element is preferably a gear switch, a pivot lever or a sliding element. These are cheap and easy to manufacture components.

Advantageously, the child seat further comprises a compartment which is designed to receive a locking part of the integral belt system, and a blocking element, the blocking element being connected to the headrest in such a way that the blocking element blocks the compartment from receiving the locking part as long as the headrest is in place is placed at a height lower than a lowest non-integral headrest position from the seat section. The advantage is described below and becomes apparent in relation to the second aspect of the invention.

According to a second aspect of the invention, a child seat is provided which has a seat shell with a seat section, a headrest, an integral belt system with a locking part, an adjustment mechanism for adjusting the height of the headrest, a compartment which is designed to receive the locking part, and comprises a blocking element. The blocking element is connected to the headrest in such a way that the blocking element blocks the compartment from receiving the locking part as long as the headrest is placed at a height which is lower than a lowest non-integral headrest position from the seat section.

The lowest non-integral position defines the lowest position of the headrest at which the change from the integral mode to the non-integral mode is permitted. Preferably, the lowest non-integral headrest position of the headrest corresponds to a child aged 3 years. Since the blocking element blocks the compartment from receiving the locking part as long as the headrest is placed at a height which is lower than the lowest non-integral headrest position, the non-integral mode is prevented from being used too early. A user attempting to stow the locking part of the integral harness system would find that this is not possible. Therefore, the user realizes that the child seat must continue to be used in the integral mode. A locking part preferably has a locking tongue of the integral belt system.

Advantageously, there is no or not enough space available in the compartment for stowing the locking parts as long as the headrest is placed at a height which is lower than the lowest non-integral headrest position. It is also possible that the compartment is inaccessible from the outside as long as the headrest is placed at a height which is lower than the lowest non-integral headrest position. The compartment preferably has a pocket for receiving the locking parts.

The connection between the headrest and the blocking element is preferably made by a rigid connection. This ensures that a movement of the headrest is transmitted to the blocking element.

Advantageously, the blocking element is further connected to the headrest in such a way that the blocking element blocks the headrest from being placed at a height that is lower than the lowest non-integral headrest position from the seat section as long as the locking part is received by the compartment. Preferably, the headrest is blocked by physical contact between the blocking element and causes the locking part received by the compartment. This in turn prevents the child seat from being used too early in the non-integral mode. The child seat is used in the non-integral mode when the child is secured to the child seat using a vehicle seat belt. As long as the locking parts of the integral belt system are stowed in the compartment, the child seat cannot be used in the integral mode. The situation in which the locking parts are stowed in or received by the compartment typically occurs when a child seat, when used for older children in the non-integral mode, is converted back into a child seat to be used for smaller children in the integral mode . In this situation, a user may find themselves using the non-integral mode with children who are not yet accessible to them. However, according to the invention, such a situation does not arise because the user is unable to bring the headrest to a position lower than the lowest non-integral headrest position. The user trying to use the non-integral mode for smaller children will thus recognize that he must switch to the integral mode in order to adjust the headrest correctly.

Advantageously, the blocking element is further configured to reduce the space available in the compartment such that the locking part does not fit into the compartment as long as the headrest is placed at a height that is lower than the lowest non-integral headrest position. It can thus be ensured in a simple manner that the locking parts are only stowed when the headrest is placed at least in the lowest possible non-integral headrest position. In addition, since there is not enough room for the locking parts to be received by the compartment while the headrest is positioned lower than the non-integral headrest position, it follows that the headrest cannot be lowered to a position lower than the lowest non-integral headrest position, as long as the locking parts are stowed in the compartment. The locking parts would physically block the blocking element in an attempt to further reduce the space of the compartment. The blocking element is preferably connected to the headrest in such a way that the blocking of the blocking element causes the headrest to be blocked.

Advantageously, the connection between the blocking element and the headrest is furthermore such that the locking part can be received by the compartment when the headrest is placed at a height which is higher than the lowest non-integral headrest position. This allows to switch to the non-integral mode when the lowest permitted headrest height is reached.

Preferably, the seat shell further comprises a backrest portion, and the compartment is integrated into the backrest portion. A compartment integrated in the backrest section of the child seat has the advantage of being easily accessible. Another advantage is that when changing from the integral to the non-integral mode, the entire integral belt system does not have to be removed. Preferably, the integral belt system can be stowed under a cover of the backrest section. The locking parts are stowed in the compartment.

It goes without saying that a child seat according to the first aspect of the invention can be combined with any feature of the second aspect of the invention and vice versa. In fact, it is particularly advantageous if the anti-misuse mechanism of the first aspect and the anti-misuse mechanism of the second aspect are integrated into a single child seat. This provides maximum protection against changing from the integral to the non-integral mode too early and against using the integral mode for too long.

Advantageously, the child seat is a combination child seat which is configured for use with the integral belt system or with a seat belt of a vehicle.

In 1a is a child seat according to the invention 100 shown. The child seat 100 includes a seat shell 1 and a headrest 2 . The seat shell 1 is used to accommodate a child. The seat shell 1 is covered with a cover. The cover is padded. The seat shell 1 has a backrest portion 11 especially to accommodate the child's back. The seat shell 1 further comprises a seat portion 12 on, which takes in particular the underside of the child and parts of his legs. The headrest 2 is shown in its lowest position. That is, the distance between the headrest 2 and the seat section 12 the seat shell 1 is minimal. This position is suitable for toddlers around 1 year of age. The headrest 2 has a central region 21st to take up the child's head. Furthermore, the headrest 2 two side sections 22nd on. These side sections 22nd have the shape of side wings. They can be padded. The side sections 22nd surround the child's head and offer protection, especially in the event of a side impact. The child seat 100 also has an integral belt system 5 on. From the integral belt system 5 are the shoulder straps 51 who have favourited pelvic ligaments 52 and the belt buckle 53 shown with locking tabs. This in 1a shown integral belt system 5 is a 5-point belt system. The shoulder straps 51 are through a management component 3 from the back (not visible) of the seat shell 1 to the front of the seat shell 1 guided.

In 1a the child seat is shown in the so-called integral mode, that is, the child seat 100 comes with the integral belt system 5 used. In integral mode are the leadership components 3 and the headrest 2 connected with each other. The connection is made via the adjustment mechanism with a connecting element, which will be described in more detail below. This connection causes the headrest to move 2 a corresponding movement of the guide component 3 . This is where the leadership component is 3 along the seat shell 1 movable. This allows the management component 3 be designed as a belt slider. Preferably, the belt slider is configured to be along the backrest portion 11 the seat shell 1 to slide and the height of the integral strap 5 adjust.

1b shows the child seat 100 out 1 a still in integral mode. In 1b became the headrest 2 moved to the highest possible position in integral mode. This position is referred to below as the “intermediate position” in order to distinguish this position from a highest possible position in the non-integral mode. The latter is the highest possible position of the headrest, which is within the child seat 100 can be achieved.

The height can be adjusted in the integral mode by operating an actuator 8th respectively. The in 1b shown actuator 8th includes a handle 81 . The handle 81 is at the top of the headrest 2 integrated. As long as the actuator 8th is operated, the headrest can be adjusted at a height between the lowest position and the intermediate position. The details of the height adjustment mechanism are described below with reference to FIG 4th to 7th described.

When comparing 1a and 1b becomes the connection of the headrest 2 and the leadership component 3 in the integral mode clearly. The distance between the headrest 2 and the leadership component 3 stay constant. This will made sure the shoulder straps 51 of the integral belt substantially horizontally from the guide component 3 be guided over the shoulders of the occupant of the child seat. This is the optimal route for the shoulder ligaments 51 to guarantee the most efficient restraint of the child in the event of a frontal collision. The lower edge 23 the headrest 2 is slightly above the 3 outlets of the guide component for the shoulder ligaments 51 . For adjusting the height of the headrest 2 it is therefore sufficient to cover the bottom 23 the headrest 2 in the correct position above the shoulders of the occupant of the child seat. Due to the connection of the management component 3 and the headrest 2 becomes a misuse or a misplacement of the shoulder straps 51 greatly reduced.

2 shows the child seat 100 from the 1a and 1b in non-integral mode. This means a seat belt 500 of a vehicle being used to carry a child in the child seat 100 to secure. The integral belt is no longer shown. According to the invention, however, it is not necessary to remove the integral belt when the child seat 100 is used in non-integral mode. The integral belt is preferably at least partially covered by the cover of the seat shell or the backrest section of the seat shell. When comparing 2 With 1b becomes apparent that the leadership component 3 has not moved, i.e. it is fixed at the same height as it was when the headrest was positioned in the intermediate position. The height of the headrest 2 has increased. This is possible because, according to the invention, the connection between the guide components is in the non-integral mode 3 and headrest 2 is resolved. Adjusting the height of the headrest 2 in non-integral mode, actuation of the actuator 8th respectively. The actuator preferably has 8th a handle 81 on that on top of the headrest 2 is positioned. The details of the height adjustment mechanism in the non-integral mode are described below with reference to FIG 5b and 6 described.

The height adjustment of the headrest 2 can be done in both non-integral mode and integral mode by operating the same actuator 8th respectively.

The referring to the 1a , 1b and 2 described child seat 100 is a so-called combination child seat. Such a combination child seat can be used for children between the ages of approximately 1 year and 12 years. This is possible due to its convertibility from a child seat with an integral belt to a child seat which, as described above, can be used with the seat belt of a vehicle.

3 Figure 3 is an exploded view of the child seat of the present invention 100 . The seat shell is shown 1 with the cover and padding removed. The seat shell 1 has a backrest portion 11 and a seat section 12 on. In the backrest section 11 are two openings 6 visible. Furthermore is in the seat shell 1 a rack 9 integrated. The rack 9 is on the backrest section 11 the seat shell 1 shown attached. The rack 9 the embodiment shown is integral with the seat shell 1 educated; however, it can also be designed as a separate part. 3 also shows a headrest 2 (with the cover and padding removed). The headrest 2 has two openings 7th on. The management component is also shown 3 for guiding the shoulder straps of the integral belt system. Also is the connector 4th pictured. A pole 34 who are the leadership component 3 and the connecting element 4th connects is also shown. Furthermore is the actuator 8th shown. The actuator 8th has a handle 81 , a conversion element 82 and an elastic component 83 such as a spring and a locking part 84 such as a locking bar. The locking mechanism according to the invention has the rack 9 and the actuator 8th on. The connecting element 4th and the locking mechanism are part of the height adjustment mechanism according to the invention. The locking mechanism is described below with reference to FIG 7th described in detail.

The openings 6 in the backrest section 11 provide a guide rail of the guide component 3 and the connecting element 4th ready when the child seat is used in integral mode. Purpose and function of the backrest openings 6 are described below in the description of the 4a and 4b obviously.

The openings 7th the headrest are designed to accommodate the guide component when the child seat 100 is used in non-integral mode. The openings 7th in the headrest allow adjustment of the headrest 2 in non-integral mode, although the leadership component 3 is fixed in the intermediate position. The further purpose and mode of operation of the headrest openings 7th are described below in the description of the 5b and 6 obviously.

The 4a , 4b , 5a , 5b and 6 show one after the other the adjustment of the headrest from the lowest position to the highest position. Specifically, in the 5a and 5b the conversion of the connecting element 4th shown from the first configuration to the second configuration.

In 4a is a headrest 2 with an opening 7th , a management component 3 and a connector 4th shown. The connecting element 4th is part of the height adjustment mechanism. Furthermore, a shoulder strap is required 51 of the integral belt system. The shoulder strap 51 is through the leadership component 3 guided. Also is part of the backrest section 11 the seat shell with a corresponding opening 6 visible. The headrest 2 is about the fastener 4th with the leadership component 3 coupled. The headrest 2 includes a recess 24 . The recess 24 is for receiving a corresponding engagement part 41 of the connecting element 4th educated. According to the in 4a The embodiment shown are the guide component 3 and the connecting element 4th by means of a rod 34 connected with each other. Other connecting means are possible. This in 4a shown connecting element 4th is designed as a gear switch. This gear switch 4th is around the bar 34 rotatably mounted. The seat pan may include guide means such as rails or a recess (not shown) adapted to support the ends of the rod 34 record. If present, these guide means must also be designed to move, e.g. B. a slide, the rod 34 along the backrest portion 11 to allow the seat shell. In 4a is the connecting element 4th placed in the first configuration. In this first configuration, the connector connects 4th the headrest 2 with the leadership component 3 . The three components connecting element 4th , Headrest 2 and leadership component 3 form a network. This composite can be along the opening 6 of the backrest section 11 the seat shell can be moved. In 4a is the headrest 2 placed in the lowest possible position.

4b shows the change in the position of the headrest 2 , the management component 3 and the connecting element 4th in relation to 4a after adjusting the height of the headrest 2 . The height adjustment during the integral mode can be achieved by operating an actuator and pulling the headrest 2 in relation to the seat pan upwards can be reached as indicated by the arrow A. specified. As long as the actuator is operated, the headrest is 2 released from engagement with the seat pan. The details of the operation are given below with reference to FIG 7th described in more detail. The configuration of the fastener 4th has not changed. The connecting element 4th is still in the first configuration. That means the headrest 2 and the leadership component 3 still through the connector 4th are interconnected in the same way as above with respect to FIG 4a described. So that the headrest 2 in the in 4b When the position shown arrives, the guide components move 3 and the connecting element 4th at least partially along the openings 6 of the backrest section 11 . The backrest openings 6 serve as guide rails to stabilize the headrest components 2 , Leadership component 3 and connecting element 4th against lateral movement. In 4b has the leadership component 3 the top of the opening 6 of the backrest section 11 reached. It has therefore reached the limit. Another increase in the height of the headrest 2 is not possible as long as the fastener is 4th is in its initial configuration. Due to the connection of the headrest 2 and leadership component 3 remains the distance between the guide component 3 , in particular that of the shoulder strap exits of the guide component 3 , and the headrest 2 constant. The fastener placed in the first configuration 4th consequently corresponds to the child seat used in integral mode. Along with the movement of the guide component 3 runs through the management component 3 led shoulder strap 51 along the backrest portion 11 the seat shell. This allows the height of the integral belt system to be adjusted. A locking mechanism designed to hold the headrest 2 with the seat shell, preferably with the backrest section 11 of the seat to engage is in relation to 7th described in detail.

The 5a and 5b show the conversion of the connecting element 4th from the first configuration to the second configuration when the headrest 2 has reached the intermediate position, ie the highest possible position in integral mode.

In 5a is the connecting element 4th of the child seat in the first configuration. In the 5a The configuration of the child seat shown corresponds to that in 4b shown. The connecting element 4th thus connects the guide element 3 and the headrest 2 . The connection could be achieved by adding an end section 41 of the connecting element 4th from a recess 24 the headrest 2 is included as above in relation to 4a described.

5b shows the child seat with the connecting element 4th of the adjustment mechanism placed in the second configuration. The headrest 2 is still positioned in the intermediate position, ie at the same height as in 5a shown. The leadership component 3 is shown how to attach it to the top of the opening 7th the headrest is adjacent. The leadership component 3 adjoins the top of the opening 6 of the backrest section 11 the seat shell. Compared to 5a was in 5b the connection component 4th around the pole 34 panned or rotated. The panning / turning is by the arrow B. specified. The Connecting element 4th is from the recess 24 the headrest 2 no longer included. The connecting element 4th however, remains with the leadership component 3 engaged. In the in 5b The embodiment shown is the latter engagement by the rod 34 reached. In the second configuration, as in 5b shown, connects the connector 4th of the adjustment mechanism the guide component 3 no longer with the headrest 2 . That is, the headrest 2 is not connected to the management component 3 versatile. Furthermore, as in 5b apparently, a respective engagement part 42 of the connecting element 4th in the recess 25th of the backrest section 11 added to the seat shell. This connects the connecting element 4th the leadership component 4th with the backrest section 11 the seat shell. The leadership component 4th is thus prevented from further movement. In other words, the height of the headrest 2 can be adjusted while the guide component 4th remains attached. The leadership component 3 cannot be placed in a higher position than the intermediate position from the seat portion of the seat pan. This prevents a user from using the child seat with the integral belt system, ie in the integral mode, for children who have already outgrown the integral mode seats.

In a preferred embodiment, the conversion of the connecting element 4th between the first configuration, e.g. B. in 5a shown, and the second configuration, such as. B. in 5b shown only possible when the headrest 2 is positioned in the intermediate position. This can be done by suitable choice of the dimensions of the recess 24 the headrest 2 , the recess 25th of the backrest section 11 and that of the corresponding engaging parts 41 and 42 the management component 4th can be achieved. In 5b is the headrest 2 in the intermediate position. In this case, when a user becomes the guide component 4th around the pole 34 pivots / rotates the recess 25th in the backrest section 11 positioned so that they have the corresponding engagement part 42 of the connecting element 4th can accommodate. Assuming that the headrest is 2 located at a height that is lower than the intermediate position would if a user tried to use the guide component 4th around the pole 34 to pivot / rotate the engaging part 42 the management component 4th on part of the backrest portion 11 rest and prevent the engagement part 41 the management component 4th completely out of the recess 24 the headrest 2 solves. Therefore, the connection between the headrest remains 2 and the leadership component 3 received unless the headrest 2 has reached the intermediate position. The same applies to the changeover from the second configuration of the connecting element 4th in the first configuration.

6 shows the change in the position of the headrest 2 , the management component 3 and the connecting element 4th in relation to 5b after adjusting the height of the headrest 2 . The height adjustment when the connecting element is in the second configuration 4th , for example in the non-integral mode, can be achieved in the same way as with the connecting element in the first configuration 4th , for example in integral mode. This means that the height adjustment can be carried out by operating the same actuator as in the integral mode and pulling the headrest 2 in relation to the seat pan upwards can be reached as indicated by the arrow C. specified. As long as the actuator is operated, the headrest is 2 released from engagement with the seat pan. The details of the operation are given below with reference to FIG 7th described in more detail. The configuration of the fastener 4th has changed in relation to those of 5b not changed. This means that, as referring to above 5b described in detail the connecting element 4th the leadership component 30th with the backrest section 11 the seat shell connects; the headrest 2 is no longer with the leadership component 3 connected. So that the headrest 2 in the in 6 position shown, the headrest moves 2 at least partially along the backrest portion 11 the seat shell. The headrest 2 includes one or more openings 7th . The headrest openings 7th ensure that the leadership component 3 the headrest 2 does not prevent movement in non-integral mode. In other words, from the frame of reference of the headrest 2 Seen from the perspective, the guide component moves 3 from the upper stop of the headrest openings 7th along the headrest openings 7th in the direction of the lower stop of the headrest openings 7th when the height of the headrest 2 as by the arrow C. specified is increased in non-integral mode. The leadership component 4th remains with respect to the backrest portion 11 the seat shell in a fixed position, preferably the intermediate position, while the headrest 2 in relation to the backrest portion 11 Moved upwards, increasing the height of the headrest 2 is enlarged. The one with the leadership component 4th cooperating headrest openings 7th as described above, in addition to stabilizing the headrest 2 against lateral movement.

In 6 has the headrest 2 the highest possible position, ie reached the highest position. The bottom of the opening 7th the headrest 2 borders on the leadership component 3 on. It has therefore reached the limit. Another increase in the height of the headrest 2 can not. As the fastener 4th the leadership component 3 not with the headrest 2 connects, remains with the height adjustment of the headrest 2 one through the Leadership component 3 led shoulder strap 51 in a fixed position of the backrest portion 11 the seat shell. The integral belt system does not have to be removed from the child seat. The height adjustment of the headrest 2 can be performed in non-integral mode despite the integral belt system installed. For convenience, it is possible to use the shoulder straps 51 of the integral belt behind the cover of the child seat. But it is also possible to remove the integral belt system from the child seat, e.g. B. for cleaning, maintenance, replacement, etc. A locking mechanism that is designed to hold the headrest 2 with the seat shell, preferably with the backrest section 11 of the seat to engage is in relation to 7th described in detail.

7th Figure 3 shows a locking mechanism that can be used to secure the headrest 2 with the seat shell, preferably with the backrest section 11 the seat shell, to be brought into engagement at different heights. In 7th a configuration is shown in which the headrest 2 with the backrest section 11 the seat shell is engaged. That is, the headrest 2 is attached to the seat shell at a certain height. The locking mechanism is part of the height adjustment mechanism of the child seat. The locking mechanism includes a rack 9 and an actuator 8th . The actuator 8th includes a handle (in 7th not shown but in 3 with the reference number 81 shown), a conversion element 82 and an elastic component 83 such as a spring and a locking member 84 such as a locking bar. The actuator 8th is with the headrest 2 of the child seat connected. The rack 9 is integrated in the seat shell, preferably in the backrest section 11 the seat shell. The rack 9 includes notches 91 that are configured to use the locking bar 84 record. The notches are spaced so that the headrest 2 is adjustable in a certain number of different heights. By means of the rack 9 is a gradual height adjustment of the headrest 2 possible. The rack 9 can be formed in one piece with the seat shell. But it is also possible that the rack 9 is formed separately and then integrated into the seat shell.

The locking mechanism is locked by locking the locking rod 84 between the conversion element 82 and the rack 9 . In this way the locking bar 84 not out of the notch 91 the rack 9 in which it is placed. The conversion element 82 transmits the movement of the handle to the movement of the locking bar 84 . The locking bar 84 can be moved in one or more recesses 26th the headrest 2 assembled. This can e.g. B. can be achieved in that the end portions of the locking rod 84 in corresponding recesses 26th be included. This is the locking bar 84 with the headrest 2 connected. When pressing, e.g. B. by pulling the handle becomes the conversion element 82 moved in the same direction. The movement of the changeover element 82 takes place against the force of the elastic component 83 . When the handle is pulled up, the diverter element compresses 82 first the elastic element 83 . As soon as a certain threshold or a stop is reached, the elastic element compresses 83 no more. In this position of the changeover element 82 is the receiving section 85 of the conversion element 82 on the notch 91 the rack 9 in which the locking bar 84 is placed, aligned so that the locking bar 84 is free to get into the receiving section 85 to move in.

If the handle is now pulled further, the headrest becomes 2 with which the actuator 8th connected, pulled up. By pulling up the headrest 2 are also the recesses 26th for those in the headrest 2 integrated locking bar 84 moved up. This will make the locking bar 84 from a notch 91 the rack 9 in the receiving section 85 emotional. The movement of the locking bar 84 relative to the headrest 2 is through the recesses 26th limited. Once the locking bar 84 from a notch 91 the rack 9 is moved out, the headrest becomes 2 released from engagement with the seat pan. The height of the headrest 2 is then adjustable. The headrest 2 can on the backrest portion 11 the seat shell can be moved up or down. Once the appropriate height is found, the user stops using the actuator 8th to operate. The elastic element 83 then drives the conversion element 82 back to its resting position. The changeover element drives on the way back to the rest position 82 the locking bar 84 into engagement with the rack 9 . The locking bar 84 can through the conversion element 82 along the recesses 26th into one of the notches 91 the rack 9 to be driven. The headrest 2 is then at a certain height in relation to the seat shell, in particular in relation to the backrest section 11 or attached to the seat portion of the seat pan.

According to the child seat according to the invention, one actuator is sufficient 8th to adjust the height of the headrest 2 in both integral mode and non-integral mode. This means that the same locking mechanism works for both modes. The one with reference to 7th The locking mechanism described can be used when the connecting element of the adjusting mechanism is in the first configuration, and when the connecting element is is in the second configuration. This means the rack 9 is preferably chosen so that it allows a height adjustment of the headrest 2 from the lowest position, ie the lowest possible position, ie the lowest possible position in the integral mode to the highest position, ie the highest possible position, ie the highest possible position in the non-integral mode.

The anti-misuse mechanism of the above-described embodiments prevents excessive use of the integral mode. However, they do not necessarily prevent a user of the child seat from using the non-integral mode too early. As described above, it is an advantage of the invention that the integral belt system does not necessarily have to be removed when switching from the integral to the non-integral mode. The user is therefore not prevented from switching to the non-integral mode, even if the headrest has not yet reached the intermediate position.

The following with reference to the 8a , 8b and 8c described embodiments provide an anti-misuse mechanism against premature use of the non-integral mode. The anti-misuse mechanism for preventing the premature non-integral mode may be used in addition to the anti-misuse mechanism for preventing the integral mode from being used for too long in the same child seat. If both anti-misuse mechanisms are used together in the same embodiment of a child seat, an improved / optimal protection against misuse is provided.

8a Figure 12 shows a child seat with an anti-misuse mechanism that prevents premature use of the non-integral mode. In 8a is a seat shell 1 of the child seat shown having a backrest portion 11 and a seat section 12 , a headrest 2 and a leadership component 3 for guiding the shoulder straps 51 of the integral belt system 5 includes. The leadership component 3 is preferably a belt slider. In addition to the shoulder straps 51 is a locking part 54 of the integral belt system 5 shown. Preferably the locking part is 54 a locking tongue, which is designed to be inserted in a belt buckle (not shown) of the integral belt system 5 to be secured. It is also shown that a blocking element 27 with the headrest 2 connected is. The backrest section 11 the child seat includes a front part 111 and a rear part 112 . The front part 111 is the part of the backrest section 12 designed to accommodate the back of a child placed in the child seat. The back part 112 of the backrest section 12 is the part facing away from the child. The front part 111 of the backrest section 12 includes an opening 551 . The opening 551 is dimensioned so that the locking part 54 fits through them. Between the front part 111 and the rear part 112 of the backrest section 12 is simple 55 arranged. The field of expertise 55 is dimensioned so that it can accommodate the locking part 54 or, if more than one locking part 54 is used to accommodate all locking parts 54 suitable is. The field of expertise 54 can comprise one or more pockets. The child seat shown is used in integral mode. That is, the integral belt system 5 serves to secure a child placed in the child seat. In this case the blocking element blocks 27 the compartment against the reception of the locking part 54 . As in 8a shown, blocks the blocking element 27 the opening 551 of the front part 111 of the backrest section 12 . It is not possible to use the locking part 54 through the opening 551 in the compartment 55 bring to. The blocking element 27 not only blocks the opening 551 and thus the entrance to the compartment 55 . The blocking element shown 27 is also dimensioned so that it is in the compartment 55 available space is reduced so that the locking part 54 wouldn't fit into him. The blocking element 27 is with the headrest 2 connected. The blocking element 27 can be made in one piece with the headrest 2 be trained. However, it is also possible that the blocking element 27 is a separate part connected to the headrest, e.g. B. is attached to it.

In addition, it is advantageous that the in 8a The child seat shown has an adjustment mechanism which has a connecting element (not shown), designed to be arranged in a first and a second configuration around the guide component 3 with the headrest 2 or the seat shell 1 to connect as described in detail above, particularly with regard to the 3 to 6 . In this case, in addition to the anti-misuse mechanism that prevents too early use of the non-integral mode, the child seat comprises an anti-misuse mechanism that prevents too long use of the integral mode.

In the integral mode shown, it is not possible for a user to use the locking part 54 in the subject 55 to stow away. As the dimensions of the tray 55 and the locking element 27 are chosen so that it is possible to use the locking part 54 only then in the subject 55 to stow when the headrest 2 has reached a lowest non-integral headrest position, the non-integral mode is avoided from being used too early.

8b shows the child seat 8a , with the headrest 2 in relation to the seat section 12 is raised to a higher position. The headrest 2 is placed in the lowest non-integral headrest position. This position is defined as the minimum possible height of the headrest 2 (in relation to the seat section 12 ) for which it is possible to use the locking part 54 in the subject 55 to stow away. In the illustrated embodiment, the blocking element 27 so with the headrest 2 associated that lifting the headrest 2 above the lowest non-integral headrest position causes the blocking element 27 the field of expertise 55 releases from the blockage. The blocking element 27 can be rigid with the headrest 2 be connected. The blocking element 27 can be made in one piece with the headrest 2 be trained. In the embodiment shown, the lower edge of the blocking element is located 27 at the same level as the top of the opening 551 . Assuming the opening 551 is dimensioned so that the locking part 54 fits through them, the lowest non-integral headrest position of the embodiment shown is achieved when the blocking element 27 the opening 551 Completely releases / unblocks. Only from a height of the headrest which equals or exceeds the lowest non-integral headrest position is it possible for a user to use the locking part 54 or locking parts 54 in the subject 55 keep or stow away. As long as the headrest 2 is arranged at a height which is lower than the lowest non-integral headrest position, blocks the blocking element 27 the field of expertise 55 . As long as this is the case, the locking parts are stored 54 in the subject 55 not possible.

In 8b is the locking part 54 not yet in the subject 55 kept. The child seat is thus used in the integral mode. However, it is possible to use the locking part 54 in the subject 55 to store as the opening 551 enabled / not blocked. In other words, the child seat could be switched from the integral mode to the non-integral mode. This can be done by storing the locking part 54 in the subject 55 can be achieved.

8c shows the child seat 8b , that is, with the headrest 2 placed in the lowest non-integral headrest position. In 8c is the locking part 54 in the subject 55 kept. The change from the integral mode of the child seat to the non-integral mode has been carried out. In the non-integral mode, the child must be secured to the child seat with the vehicle's seat belt. When you continue to raise the headrest 2 also becomes the blocking element 27 raised. On the other hand, when lowering the headrest 2 in non-integral mode with that in the compartment 55 stored locking part 54 the following situation will occur. When the blocking element 27 rigid with the headrest 2 is connected, the blocking element 27 when lowering the headrest 2 lowered. A user tries the headrest 2 lowering below the lowest non-integral head restraint position, the blocking element arrives 27 consequently in contact with the locking part 54 . The locking part 54 thus physically blocks the blocking element 27 against an upward movement. The blocking of the blocking element 27 locks the headrest 2 . This means that it is not possible to use the headrest 2 lower to substantially lower heights than the lowest non-integral headrest position as long as the locking member 54 in the subject 55 is kept. This prevents a user from switching back from the non-integral mode to the integral mode for children who are too young.

As described above, it is advantageous that the 8a , 8b and 8c The child seat shown comprises an adjustment mechanism comprising a connecting element which is configured to be placed in a first and a second configuration around the guide component 3 with the headrest 2 or the seat shell 1 to connect, as in particular with regard to the 3 to 6 described in detail. In this case the lowest non-integral headrest position is in a position that is less far from the seat section 12 is removed than the intermediate position in which the change from the first configuration of the connecting element to the second configuration is possible. The intermediate position defines the highest possible position of the headrest 2 in integral mode. The lowest non-integral headrest position defines the lowest possible position of the headrest 2 in non-integral mode. Preferably, the intermediate position corresponds to children aged 4 years. Preferably, the lowest non-integral headrest position corresponds to children 3 years of age. Between the lowest non-integral headrest position and the intermediate position, the child seat can be used in both integral and non-integral mode.
