Description

Child seat for attachment to a motor vehicle

description

The invention relates to a child seat for attachment to a

A motor vehicle seat comprising a seat member and a base.

From EP 1 954 523 Bl a rotatable child seat for motor vehicles with a base frame is known, which has a substantially vertically extending

Having back portion and a substantially horizontally extending bottom portion, wherein the base frame can be arranged on a vehicle seat and held there with an in-vehicle seat belt system. Furthermore, the child seat has a seat shell system which has a seat shell and a connection element provided on the underside of the seat shell system, wherein the connection element is provided with a correspondingly complementary thereto and provided on the bottom region of the base frame

Connecting element is engageable such that between the

Base frame and the seat a positive connection is formed. The seat pan system is rotatable about a substantially vertical axis of rotation formed with the connecting elements relative to the base frame in a first position, in which the seat pan points in the direction of travel, and in a second position, in which the seat pan points counter to the direction of travel.

The rotation according to the prior art increases the variability, but also the risk of incorrect operation. It is therefore an object of the invention (at high variability), to ensure improved safety for a child sitting in the child seat (baby) and in particular to reduce the risk of incorrect operation.

This object is achieved by a child seat according to claim 1.

In particular, the object is achieved by a child seat, comprising a seat element and a, attachable to a vehicle seat, base, wherein the

Seat member relative to the base of a first orientation in a second, different from the first orientation, orientation is rotatable, wherein a headrest of the seat member in the first orientation in different

Configurations, in particular with respect to a height of the headrest, is adjustable, wherein at least one first blocking device is provided, which prevents in a possible part of the configuration in the first orientation prevents the seat element is rotatable from the first to the second orientation and / or at least a second blocking means is provided which prevents a portion of the configurations possible in the first orientation being adjustable in the second orientation.

A central idea of the invention is to provide a blocking device, so that it is prevented that certain (hazardous) configurations of the headrest can be taken in at least one of several possible orientations of the seat element. As a result, a faulty operation can be excluded from the outset, which increases security.

Under an "orientation" in the present context, the orientation of the seat element with respect to the vehicle direction or the viewing direction of the child to understand. In a forward orientation, the child looks forward, in the direction of travel. In an orientation to the rear, the child looks back, towards the backrest. An axis for the orientation change is in particular, at least substantially, vertically.

The seat member is rotatable from a first orientation to a second orientation. This means in particular that the seat element in the

Alignment change basically remains on the base (so this at least contacted). In particular, this rotation is without simultaneous Translational movement (of the seat element relative to the base)

allows. Removal of the seat member from the base to effect rotation is not necessary. In particular, between the first and second alignment still intermediate positions (by rotation or rotation) can be taken. It may therefore be an angular range

be run continuously. Optionally, in addition to a change of orientation (ie a rotation about an at least substantially vertical axis), an inclination of the seat element can be changed (which also corresponds in a certain sense to a rotation, hereinafter the term "inclination" or " Tilt change "are used). An orientation change axis is not identical to an inclination (or tilt) axis. The axis for the

Alignment change is in particular (at least substantially) perpendicular. The axis for the inclination (ie the tilting) is a (in installation position of the

Child seat) at least substantially horizontal axis. The inclination thus concerns an inclination or tilting of the seat, for example the

Transferring the seat element from a rest position (lying position) in a sitting position, or vice versa. In particular, the various configurations of the headrest relate to a height of the headrest (alternatively or additionally, the various configurations may also be characterized by different angles of the headrest relative to the seat back and / or positioning and / or angle adjustment of side walls or the like). The height of the headrest may optionally be adjusted continuously or in discrete steps (for example, in at least two or at least three or at least five steps). First and second blocking means may be formed by a (at least partially) common structure. In this respect, it is also possible that the second

Blocking device by the first blocking device (mit-) is formed.

Preferably, the first orientation corresponds to a configuration of

Child seat, where the seat element is directed backwards (ie the child is looking at the backrest of the vehicle seat on which the child seat is mounted). The second orientation may correspond to a configuration of the child seat, in which the seat element is directed forward (so the child looks in the direction of travel). Thus, the first orientation may be a reverse orientation, the second orientation may be a forward orientation. According to this

Training is thus prevented in particular in forward orientation that certain configurations of the headrest are enabled. For example, a lowest altitude or the two or more (or three or more) lowest altitudes may be blocked such that the child seat is only configurable in forward travel for relatively large children. Thus, the user recognizes immediately that he (or baby) can not carry a small child (or baby) in forward orientation, as he then can not configure the child seat for the small child (baby) accordingly. It is exploited that the headrest is an element that is usually adjustable. Furthermore, the height of the headrest is a good "indicator" of the size of the child.

According to the invention, therefore, this basically existing relationship between the size of the child on the one hand and the height of the headrest on the other hand was exploited in order to improve safety.

The child seat may additionally be rotatable in a third orientation. The third orientation is preferably between the first and second orientations. In particular, the third orientation may have an angle of 90 ° with respect to the first and / or second orientation. Particularly preferably, the child seat can be locked in this third orientation. Also in the first and / or second orientation of the child seat is preferably lockable (with corresponding locking means may be provided), regardless of the possibility of a third orientation. The child seat may thus be rotatable in at least three orientations (for example in the forward orientation, in the rearward orientation and in a direction transverse to the direction of travel, at a 90 ° angle to forward and backward alignment, respectively). If appropriate, the child seat can also be rotatable and in particular lockable in a fourth orientation (in particular mirror-inverted to the third orientation). The fourth orientation may have an angle of 180 ° with respect to the third orientation. It is also conceivable to make the child seat lockable in more than three or four orientations. In particular, the child seat in principle (without that he must necessarily be lockable in all positions must be rotatable over the full 360 ° angle. By (possibly lockable) third orientation in particular the insertion and removal of the child can be facilitated in or out of the child seat. This simplifies the operation of the child seat.

A rotation of the child seat in the third orientation may preferably also be possible in those configurations of the headrest, which in the second Alignment are blocked. As a result, it is preferably possible that the child seat is rotated out of the first orientation (optionally in the direction of the second orientation) (preferably also in the configurations which are prevented in the second orientation), so that at least the third orientation can be assumed (FIG. and possibly only then the blocking device acts, so that a further rotation in the direction of the second orientation is not possible). As a result, the safety and operability is improved at the same time, as well as a small child (without having to change the headrest), at least can be brought into a position from which it can be easily inserted or lifted out. Nevertheless, it is effectively prevented that the comparatively small child (baby) is positioned looking forward while driving.

First and / or second blocking means can be configured such that at least one lowest (possibly at least the two lowest or at least the three lowest or at least the four lowest), possible height in the first orientation (possible heights) of the headrest in the second Alignment is blocked. This further improves safety.

At least one highest (preferably at least the two highest or at least the three highest or at least the four highest), in the first orientation possible height (s) of the headrest can (can) also be set in the second orientation (ie not by first and / or second

Blocked blocking device).

In general, the part that is possible in the first alignment

Configurations that are not possible in the second orientation are at least one configuration (height), preferably at least two configurations (heights), more preferably at least three configurations (heights), even more preferably at least four configurations (heights).

Alternatively or additionally, a part of the possible configurations of both the first orientation and in the second orientation at least one, preferably at least two, more preferably at least three, even more preferably at least four configurations (heights) form.

First and / or second blocking device can be (at least partially) actuated or triggered by rotation and / or translation of the headrest. Preferably, a blockage is achieved in that the headrest of is moved up and down. Preferably, in at least one uppermost position of the headrest (preferably at least in both uppermost positions, more preferably at least the three uppermost positions, even more preferably at least four uppermost positions) of the headrest a rotation of the child seat over an angle of at least 180 °, preferably of at least 360 °, possible (ie not blocked by the blocking device).

In one embodiment, at least one third blocking device

provided, which prevents at least in a lying position of the seat element, that the seat element is rotatable from the first to the second orientation.

Alternatively or additionally, at least one fourth blocking device can be provided, which prevents at least one lying position being adjustable in the second orientation. In general, the child seat can be designed so that its inclination is changeable (adjustable) (in particular with respect to the base). It is conceivable that the inclination in the plurality (at least two or at least three or at least four) discrete

Positions is adjustable or is continuously adjustable over a certain range of angles. Preferably, at least one "lying position" and a

"Sitting position" possible, wherein the seat element in the "lying position" (or rest position) is aligned flat (especially with respect to the base) than in the sitting position. The third and / or fourth blocking device prevents a particularly flat inclination in certain constellations, in particular in the forward orientation of the child seat, can be taken. This further improves safety.

In one embodiment, a rotation of the child seat is only in a (maximum) upright position (sitting position) of the seat element allows (in this case, rotation in all other inclinations of the seat element is excluded). An "upright position" in this sense can be defined in particular by a sub-angular range which forms a subset of a generally possible angular range over which the seat element can be inclined (for example at least 10% or at least 20% and / or at most 90% or at most 70% of this total angular range). This can prevent the child from being rotated while lying, so that safety is further improved. Preferably, an inclination of the seat member is detected during a rotation from the first to the second orientation and / or in the third orientation. The inclination of the seat element can therefore be variable in particular only in the first and / or second orientation. This prevents the alignment from being changed and the tilt from being changed at the same time, which makes the adjustment easier to control and thus increases safety.

Between the headrest and a blocking element (in particular locking element) of the first and / or second blocking device, an operative connection can be formed. This preferably comprises at least one (push and / or pull) rod and / or at least one (start-up) inclined surface and / or at least one link or link guide. As a result, the comparatively long path between the headrest and the base can be bridged in a structurally simple manner, so that a movement of the headrest (in particular height change) at the base can cause a blockage.

In a preferred embodiment, a (in particular the above-mentioned) blocking element of the blocking device is rotatable into its blocking position.

As a result, a comparatively large travel path of the headrest can be converted into a comparatively small movement of the blocking device (in particular downwards), so that a small-sized blocking device is made possible. This simplifies operation and production of the child seat.

According to a general idea, an operative connection between headrest and blocking element is designed such that a comparatively large movement of the headrest (upwards or downwards) is converted into a smaller, in particular considerably smaller, movement of the blocking element (upwards or downwards).

In one embodiment, an (additional) release mechanism is provided such that actuation of the release mechanism, a blocking position of the first and / or second blocking device, in particular a blocking position of (in particular the above) blocking element of the first and / or second blocking device, can be canceled. Such a release mechanism is provided according to the embodiment in addition to an optionally actuated by the headrest mechanism or works independently of a movement or Position of the headrest. For example, this release mechanism may allow for a basically blocked adjustment (with a corresponding headrest configuration) to still be enabled by operation of the release mechanism, so that a configuration that is basically not possible with a given headrest configuration can also be adopted. Alternatively, such a

Release mechanism, however, also be waived, in the sense that with appropriate adjustment of the headrest a certain orientation is not possible (not even by pressing a separate mechanism). The release mechanism can be operated (in particular by hand)

Actuator include. Furthermore, the release mechanism may be configured so that a release (unlocking) by a translational and / or (preferably) rotational movement of (the) blocking element takes place. Such an actuating device may optionally be concealed. Basically, such a release mechanism allows the setting of a really undesirable configuration, which, however, in certain

Situations (for example, for cleaning or positioning the

Child seat, if it does not depend on the safety, for example, parked vehicle) is desired.

The first and / or second blocking device preferably has at least two stops which correspond to one another. The first blocking device may, for example, have two (at least substantially) vertically extending abutment surfaces which correspond to one another. The second

Blocking device may for example have two (at least substantially) horizontally oriented, mutually corresponding stop surfaces. Overall, this allows blocking in a structurally simple manner.

In the following description, the same reference numerals are used for identical and equivalent parts.

Figure 1 shows a child seat according to the invention in an oblique view. The child seat is in reverse orientation, lying position and high

Headrest. In detail, the child seat has a seat element 10, a base 11 and a support foot 12. The seat element 10 includes, inter alia, a headrest 13, which is adjustable in height. In Figure 1, the headrest 13 is in a highest possible position. In Figure 2 (which otherwise corresponds to Figure 1), the headrest 13 is in a lowest possible position. FIG. 3 in turn corresponds to the configuration according to FIG. 1 with regard to the headrest 13. In contrast to FIG. 1, however, the child seat here is in an upright (maximally upright) position (sitting position). The configuration according to FIG. 4 again corresponds to the configuration according to FIG. 13 with the difference that here the headrest 13 is again in its lowest possible position.

FIG. 5 corresponds to the configuration according to FIG. 3, with the difference that the seat element 10 is not configured in a backward orientation, but in FIG

Forward orientation (so that the child looks in the direction of travel while driving).

FIG. 6 shows the child seat according to FIG. 5 in an exploded view. As can be seen, the headrest 13 is connected to a rod 14 having sloping edges 15. When the headrest 13 is moved down, this rod moves (with the oblique edges 15) with the headrest down (and vice versa with the headrest up when moving it up). About the rod 14 is then (which will be described in detail below) brought a blocking element in its blocking position. Furthermore, a rotational receptacle 16 of the base 11 can be seen in FIG. 6, within the one

corresponding rotatable bottom element 17 of the seat member 10 is rotatably received. The reference numerals 18 indicate

Side impact protection elements which are hinged (and are not further relevant or essential in this context).

Figures 7 and 8 show parts of the child seat, in particular a

Blocking element 19, which depending on the position of the headrest 13 (not shown in Figures 7 and 8) can rotate downwards (which will be explained further below). For this purpose, the blocking element 19 is mounted on at least one axis 20 (see FIG 9), so that it in a Nachuntenbewegen a

Transmission element 21 is rotated downward. The blocking element 19 can also be seen in FIG. The transfer element 21 has at least one sheet 22 which presses against a pin 23 (see Figure 9), so that the blocking element 19 is moved downwards (or rotated). FIG. 16 then shows the blocking element 19 in its blocking position.

In the figures 11 to 13 parts of the mechanism are shown, which for the

Transfer of the blocking element 19 in its blocking position are of importance. FIG. 11 shows the headrest 13 in a high position. If the headrest 13 is now moved downwards, the rod 14 likewise moves downwards until its oblique edges 15 (see FIG. 12) come to rest at the level of movable elements (rods) 24. If the rod 14 now moves even further down, the movable elements 24 are moved by the oblique edges 15 to the outside.

As shown in Figure 13, these outwardly moving movable members 24 again push the transmission members 21 downwardly, as shown in detail in Figures 14 and 15. In FIGS. 14 and 15, respective sections of a movable element 24 and of a transmission element 21 (namely its upper end) can be seen. In Figure 14, a (radially projecting) pin 39 of the movable member 24 is in contact with a

Inclined surface (starting slope 25 of the transmission element 21). When the movable element 24 is moved outwards (to the left in FIG. 14), it slides the pin 39 along the inclined surface 25, so that the transmission element 21, as shown in Figure 15, is pressed down. As a result, the already described above movement of the transmission element 21 can be realized down. It is essential here, in particular, that a comparatively large distance of the headrest 13 in a relatively small way of

Transmission element 21 is converted.

FIG. 17 shows in detail how a lower end 26 of FIG

Transmission element 21 (or the sheet 22) on the pin 23 of the

Blocking element 19 presses so that it is pressed down into the blocking position. Because of at least one (actually two)

corresponding second blocking element / s 27 (see also FIG. 16) on the base 11, the first blocking element 19 can now not be moved further, so that due to the operative connection via transmission element (s) 21,

movable element (s) 24 and rod 14 and the headrest 13 can not be moved further down (although this would otherwise not be excluded).

In Figure 18, the first blocking element 19 and the two second

Blocking elements 27 can be seen in a view from above (together with other parts of the child seat). Furthermore, at least one (concretely two) third blocking element (s) 40 is provided, which in the

Reverse orientation of FIG. 18 prevents (prevents) rotation over a 90 ° position when the headrest is positioned comparatively far down. The first blocking element and the third blocking elements (40) are associated with a first blocking device which, in a part of the configurations possible in the first orientation, prevents the seat element (10) from being rotatable from the first to the second orientation. The first

The blocking element (19) and the second blocking elements (27) are associated with a second blocking device which prevents a part from the configurations possible in the first orientation being adjustable in the second orientation.

In the embodiment according to FIG. 18, a rotation from the first to the second orientation is excluded in a specific configuration of the headrest (absolute). Alternatively, however, an additional

Release mechanism (not shown in figures) be provided (at in particular otherwise the same embodiment), which makes it possible, even in those configurations (in particular height adjustment) of the headrest, in which actually cause the blocking elements blocking (so that rotation from the first to the second orientation is not possible) by actuation of an actuator ( for example comprising a handle or button or lever or the like), for example, the blocking element 19 is moved (in particular pivoted) in such a way that such a rotation is nevertheless possible. This may, for example, for cleaning purposes or the like or in other situations where such rotation is desired, but it does not pose a security problem (such as when parking the

Vehicle) are possible.

In Figure 18 are still fourth blocking elements 28 can still be seen, the maximum possible flattening (inclination) of the child seat in the

Restrict forward orientation, while allowing reverse orientation. For this purpose, an underside of the seat element 10 is corresponding

educated. Concretely, fifth, in the figures 19, 21 and 22 recognizable, blocking elements on the underside of the seat member 10 may be formed. These fifth blocking elements strike the (asymmetric) fourth

Blocking elements 28 so that only a certain inclination can be achieved and in particular the child seat in the forward orientation can be set less flat than in the backward orientation.

FIG. 19 shows a configuration of the child seat in rearward orientation and with a deep headrest 13. Due to the operative connection via rod 14,

Also in this case, the transmission elements 21 and the movable elements 24 described above are pushed down the first blocking element 19 as far down as it would not work in the forward direction due to the second blocking element 27. However, after an element corresponding to the second blocking element 27 is missing on the other side of the child seat (corresponding to the side on which the backrest is arranged in rearward orientation), an even lower position of the headrest 13 can be assumed here. Overall, it is therefore possible that a comparatively small child can also be recorded in reverse orientation, but in forward orientation only a comparatively large child, because otherwise the headrest could not be adjusted accordingly. Figures 20 to 23 show sections of the child seat to illustrate a locking of the rotational position of the child seat. In Figures 20 and 21, the child seat is in a transverse orientation, transverse to the forward or

Reverse orientation. This transverse alignment may e.g. correspond to the third or fourth orientation. By this orientation, the child, for example, particularly comfortable in the child seat in or out of the child seat

be lifted out. In the transverse orientation according to FIGS. 20 to 21, a hook element 30 which can be rotated about an axis 29 engages with a hook-shaped end 31 in a (comparatively flat) recess 32. This ensures at least a certain locking. However, this locking can be solved by force (for rotation of the seat) and in that regard, rather than "snapping" are considered. Furthermore, an L-section 33 of the hook element 30 encloses a locking bar 34, which blocks a tilting position of the child seat by reaching through elements 35, 36 which are in principle movable relative to each other. Here is the

Locking rod 34 in a certain inclination position basically simultaneously in two corresponding recesses of the elements 35, 36. The fact that now according to Figures 20 and 21, the locking rod 34 is not movable, and the inclination position can not be changed.

This is different in the rotational position according to Figures 22 and 23. There, the hook-shaped end 31 of the hook member 30 is rotated so far that the

Locking rod 34 is released and thus can change their position. The rotational position according to FIGS. 22 and 23 may correspond to the forward orientation and / or the reverse orientation. In any case, that is

hook-shaped end 31 received in a locking receptacle 37. To allow a rotation or change the orientation of the child seat, the hook-shaped end 31 is then pivoted out of the locking receptacle 37, wherein in this state, in turn, the locking rod 34 is encompassed by the L-section 33 of the hook member 30, so that a change in inclination is not is more possible, until the hook-shaped end 31 in turn (in particular after a 180 ° rotation) engages in a corresponding latching receptacle 37. For the production of the latching according to Figures 20 to 23, a return spring 38 (see Figure 23) is provided, which can push the hook-shaped end 31 into the corresponding latching receptacle. It should be noted at this point that all parts described above, taken alone and in any combination, especially in the

Drawings shown details are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
