Description

CHILD SEAT WITH CATCHER FOR MOUNTING ON A MOTOR VEHICLE SEAT

description

The invention relates to a child seat for attachment to a

Automotive seat.

Such child seats often have a catching body, which should hold the child especially in the event of an impact. Such a catcher is known for example from US 5,685,604, US 5,275,464 or US 5,507,558. Furthermore, it is known from the cited documents to rotate the catch body either to laterally arranged axes of rotation. The catcher can still be solved on one or both sides, so optionally also be completely removed.

It is an object of the invention to propose a child seat with catching body, which can be used in a relatively safe manner. In particular, the risk of operating errors should at least be reduced.

The above object is achieved in particular by a child seat for mounting on a vehicle seat (preferably motor vehicle seat), wherein the child seat comprises a catching body. According to a first aspect of the invention, the child seat and catching body is preferably configured such that the (complete) Disassembly of the catching body from a main body (the child seat) in at least a first configuration of the child seat and / or in at least a first state of use of the child seat is prevented (blocked).

According to a second aspect of the invention, which can optionally be combined with the first aspect, the child seat with catching body is configured such that the partial or at least complete assembly of the catching body to a main body (of the child seat) at least in a second configuration and / or prevented (blocked) in at least a second state of use of the child seat. According to a third aspect of the invention, which may preferably be combined with the first and / or second aspect, the child seat with catching body is designed such that the possibilities (structural or constructive of given options) for configuring the child seat and / or installing the Child seat of one

Depend on attachment state of the catching body.

According to the safety in the use of the child seat is improved. According to the first aspect, disassembly of the catching body from the main body (at least in one or more specific

Configuration (s) or in one or more specific conditions of use / - be prevented. This can be prevented in particular that the catch body is completely removed from the child seat and the child seat is ultimately then used without catching body (if use is actually required). Similarly, it is also according to the second aspect so that any misuse and thus

Safety disadvantages can be avoided or at least made less likely if the child seat is set or used in such a way that a catching body is not desired (for example, for a comparatively large child, in which then possibly the motor vehicle seat belt can be used). Also due to the functional (implicitly requiring a corresponding structural expression) context according to the third aspect, the security is improved because the configuration or use of the

Child seat can only be allowed for attachment states of the catching body, in which such a mounting state is also useful. For example, the adaptation of the child seat to a comparatively small child may be allowed only if the catch body is attached to the main body and thus at least impose its use. According to the embodiment, the (complete) disassembly of the catching element is absolutely prevented (in all configurations and / or conditions of use). In such an embodiment, the catching body is therefore forcibly connected to the main body in each case.

A prevention of disassembly or assembly is to be understood in particular that the corresponding assembly / disassembly (at least in the respective configuration or the respective state of use) is impossible (without damaging the child seat) or at least (clearly) difficult, for example in that disassembly / assembly is possible only after prior actuation of an actuating device, which, however, is difficult to access (for example) (completely) in the respective configuration or the respective state of use (or in general). To prevent assembly or disassembly, at least one corresponding assembly and / or disassembly prevention device can be provided.

An attachment state of the catching element is to be understood in particular as to how far the catching element is completely, partially or not at all attached to the main body (or connected to it). A complete attachment is in particular present when the catching body is connected to the main body (conclusive, in particular positive and / or positive locking or holding) at all intended fastening points (eg on both sides). A partial fastening state is present when the catching body is connected to the main body (conclusive, in particular positive and / or positive locking or holding) at least at one point, but not at all intended points. The catcher is not attached at all

in particular if it is not connected to the main body (indirectly or directly, conclusively, in particular force-locking and / or positive-locking or holding), if necessary, it is merely touched or spaced therefrom.

An absolute prevention of disassembly is preferably to be understood that disassembly not (or only with destruction of the

Child seat) is possible and that regardless of how the child seat is configured or used. Under a configuration of the child seat is in particular an adjustment of the child seat in terms of its use, in particular with regard to a size of the child to understand. Specifically, the configuration can be a

Pivoting and / or translational displacement (movement) of a child supporting part (eg seat, backrest, headrest, side wall). Concretely, the (first and / or second) configuration may be an orientation of the child seat relative to a base and / or a configuration, in particular inclination, a backrest of the child seat and / or a configuration, in particular inclination and / or height adjustment, a headrest of the child and / or to a configuration, in particular pivoting and / or width adjustment and / or height adjustment of side cheeks of the child seat.

An orientation of the child seat is to be understood, in particular, as the rotational position of the child seat about an (at least substantially) vertical axis, for example a forward orientation, in which the child looks (in use) in the direction of travel or a backward orientation in which the child (FIG. in the

Use) contrary to the direction of travel looks. Such an orientation can optionally be variable continuously or in discrete steps. In addition to the already mentioned forward and / or backward orientation can also be an example to perpendicular orientation (to facilitate the on or

Getting off the child) allows. Overall, the child seat may possibly be rotated relative to a base, for example by the fact that the

Child seat basically remains on the base, but by means of a

Rotary mechanism is rotated relative to this and / or in that the child seat is removed from the base, then rotated and mounted in a different orientation on the base again.

The inclination of the backrest can optionally be adjusted continuously or in discrete steps over an angular range of, for example, at least 10 °.

The inclination of the headrest (with respect to the backrest or a horizontal plane defined by a position of use of the child seat) may optionally be varied over a range of at least 10 °. The height of the headrest and / or The side cheeks of the child seat may / may optionally be varied over a range of at least 5 cm, preferably at least 10 cm.

A (first or second) state of use is to be understood in particular as meaning a state of the child seat in relation to possibly external elements / devices, in particular with regard to a child and / or a vehicle

(In particular its vehicle seat) and / or a (possibly external) child seat base. It should be noted that in principle a possibly provided base (even if it is removable from the child seat) can be regarded as part of the child seat or as a separate element for mounting the

Child seat.

In particular, the respective (first and / or second) use state may be a state with the child seated on the child seat or a state without the child seated on the child seat. Furthermore, the respective (first and / or second) use state can be a state in which a rear side and / or a lower side of the child seat is / are accessible or a state in which the rear side and / or underside of the child seat are not accessible is / are. Further, the respective (first and / or second) use state may be a state in which the child seat is disposed on a base or a state where the child seat is not disposed on a base. Furthermore, the respective (first and / or second) use state may be a state in which the child seat is arranged on a vehicle seat or a state in which the child seat is not disposed on a vehicle seat.

The catching body can have a transversal section. At its lateral ends, the catching body (right or left) can be straight or curved, in particular bent backwards, backwards-downwards or downwards (in the direction of the child when it is accommodated in the child seat). The catching body can each have, at least in sections, a padding and / or a possibly hard and / or dense or nonporous support structure. The transversal section can have a (transversal) length which is in particular at least 1.2 times, preferably at least 1.5 times and / or at most 6 times, preferably at most 4 times as large as a height of the catching body (ie in particular its dimensioning in a direction perpendicular to the transverse direction and perpendicular to a thickness direction or perpendicular to a direction pointing in the direction of travel). In cross section, the catching body (including and / or without padding) may be C-shaped or U-shaped, wherein the C-legs or U-legs are optionally at most 0.8, preferably at most 0.6 times as long like a section connecting the C-legs or U-legs

(Transversal section) of the catching body. The padding may optionally comprise a structure with cavities, for example formed by a foam and / or filling material and / or a honeycomb and / or cell structure. The catcher may further comprise an airbag or parts of an airbag system. Airbag or parts of the airbag system are preferably in

Catch body received and / or attached to the airbag.

Furthermore, the catching body can have one (or more) belt guide (s), which make it possible to take up at least one belt (integrated in the child seat or external) and to guide it accordingly. Alternatively, the catch body may be formed without belt guides.

The catching body can be connected or connectable to the main body (for example at a right and left end of the catching body) at several points (points or sections). Preferably, the catcher body is detachable from the main body at each of the plurality of locations, but more preferably not at all of the multiple locations (points) simultaneously. Preferably, the

Catcher (or corresponding connection means) are configured so that it in at least one configuration and / or in at least one

Use state (constructive) is excluded that at the same time at each of the several places the catching body from the main body (completely) is solved.

In a specific embodiment, the catching body can be connected to the main body at a right and a left side of its transverse section (attachable thereto), but not simultaneously detachable from both the right and the left side.

At each of the plurality of locations (or points where the catcher body is connectable or connected to the main body), a locking device, in particular (in each case) comprising a locking device (eg latch) and / or an actuating device (eg actuating button and / or slide) for locking and / or unlocking the mounting of the catching element at the respective point.

The locking device may comprise a belt tongue and / or a buckle. Furthermore, the locking device may comprise a bolt or pin, for example, in holes and / or recesses of a

Counterstructure intervenes. Alternatively or additionally, the

Locking device comprise an element, for example, in a

Rack engages. Preferably, a movable element

(Locking element) is provided, which is movable between a locking position and a released position. Furthermore, at / on each

(Fixing) point, z. B. each page a release mechanism may be provided which includes, for example, a button and / or a slider and / or the like.

In principle, it is preferable that all connections (fixings) are detachable at all points (points), but preferably not all at the same time.

In embodiments, the child seat may include a main body and a

Include catching bodies, wherein the catching body comprises (at least) one (possibly two) fastening belt (s) with (at least) one (possibly two) belt tongue (s) cooperating with (each) a buckle on the main body. In particular, between the (two) belt locks one (possibly partially fixed or at least substantially rigid, preferably odd or to one

Receiving space for the Kiond guided around) clutch device, in particular clamp (actually designed as a rod) arranged, which can take two positions. In a first position, the one tongue tongue in

Actual connection (cooperation, especially engagement) with the associated buckle. In a second position, the other belt tongue in

Actual connection (cooperation, especially engagement) with the corresponding buckle. The belt tongues can each have a recess (hole). The switching of the coupling device (clamp) from the first to the second position (or back) is preferably (only) possible if both belt tongues cooperate with the respective belt locks. To change The child seat preferably has a (in particular manually operable) mechanism or actuator, for example a switch or knob or slide, wherein a rotary switch may be provided concretely. Furthermore, each buckle may have an unlocking mechanism by means of the belt tongue and buckle can be solved from each other.

The unlocking mechanism may include a push button (or other manually operable device), which may be colored red, if necessary. In order to avoid that a user understands the red signal color on the locked side as a request to release (where a release may possibly be prevented anyway), a cover for the unlocking mechanism of the locked side can be provided, this (manual) to be placed can or automatically when the rotary switch is pressed. In an automatic

Cover may possibly at the same time the unlocking mechanism

(Unlock button or push button) on the opposite side are made accessible again (possibly also automatically).

Furthermore, each buckle may have a locking device (locking element), the (the) penetration of the corresponding end of the

Coupling device in a receiving space of the buckle (for cooperation with the recess / the hole of the belt tongue) prevents when there is no belt tongue in the buckle. This locking device can be moved away from a blocking division (for example displaced or twisted) into a recess, possibly by penetration of the belt tongue into the receiving space of the belt buckle

Unlocked position, so that a way for the end of the coupling device is free. The locking device may be spring-loaded and / or go back to the blocking position when removing the belt tongue from the buckle.

The locking devices, in particular their locking devices and / or actuating devices, of at least two of the plurality of points are preferably in operative connection with one another, for example mechanically and / or electrically (electronically), in particular such that unlocking of the first of the at least two locking devices is only possible when a second of the at least two locking devices is in an interlocking state. Specifically, a mechanical connection via a rigid or a flexible element, such as linkage or cable (Bowden cable) take place. A mechanical (active) connection can be arranged in the main body of the child seat and / or in the catching body.

A loosening of a fastening (connection) at a first location (in particular on a first side) preferably leads via the operative connection to the fact that the release of the attachment is blocked at a second location (in particular on the second side), in particular (exactly) up to Reinstallation in the first place (the first side).

A loosening of the attachment (connection) at a second location (on the second side) preferably via the (active) connection to the fact that a release of the attachment (connection) at the first location (on the first side) is blocked, in particular (exactly) until (second) fixing at the second position (on the second side).

In a preferred embodiment, blocking means may be present at several locations (especially on both sides) associated with attachment means (attachment mechanisms) at their respective locations (on their respective sides). Each blocking agent is preferably between one

Release position in which it does not block the release of the associated attachment and a blocking position in which it can block the release of the associated attachment (as an option), movable.

The plurality of (two) blocking agents may be interconnected via the (active) connection, preferably such that there is always exactly one blocking agent in the blocking position and at least one other (the other) blocking agent in the release position. Thus, it is preferably never possible to use both blocking agents in the blocking position or both blocking means in the blocking position

Be release position. A transfer of a blocking agent is preferably inevitably accompanied by the transfer of the other blocking agent. The

Conversion of the respective blocking means should take place precisely then (and preferably only) when the fastening devices (fastening mechanisms) are closed on both sides and a release on the side (or in general: at the point) is initiated, on which the corresponding Blocking agent in the blocking position is. The transfer of the

Blocking means (possibly directly) by an actuation of the release mechanism or by a transfer of the locking device (the

Locking element) of the locking device (of

Mounting mechanism) in the released position. Further preferably, the locking element (locking device) in turn blocks a transfer of the blocking means in its released position.

Overall, several states are conceivable. According to a first state, a fastening can be released at a first location (first side) and the blocking means can be in the release position and at a second location (second side)

Attachment closed and the blocking agent in blocking position, wherein the blocking means are not transferable. According to a second state, the attachment may be closed at a first location (first side) and the blocking means may be in the blocking position and the attachment may be closed at a second location (second side) and the blocking means may be in the release position, the blocking means being transferable. Reciprocal states (in which the first digit / page is exchanged with the second in the preceding) are also grateful.

Alternatively or in addition to a mechanical (active) connection, an electrical connection (wireless or wired) may be provided, if necessary with sensors for detecting a fastening. A movement / actuation of blocking means can then, for example, via electromagnets and / or

Electric motors or the like take place. In such an embodiment, other components, such as an energy storage and / or a connection for a power supply, a memory unit for the storage of

Program code, a processor and / or sensors may be used to allow control of electric drives (motors) or electromagnets.

In a further embodiment, a non-detachable (in particular not detachable) connecting device, for example comprising a cord and / or a rope and / or a chain and / or a belt and / or a belt, may be provided between the catching body and the main body. The

Connecting means is preferably adapted to be in Use state of the catching body receives at least no significant forces (for example, in the case of an impact) or at least in

Essentially, no child (back) holding function has. Optionally, the connection means may also have a restraining function, for example by e.g. at least (or exclusively) the so-called submarining

(Slipping under the catcher) prevented. In particular, the connecting device may be such that it is in a state in which the child is housed in the child seat and held by the catching body (fixed) is under no pressure and / or under no tension, but, for example, limp down. The (non-detachable) connection device may functionally resemble a leash for a ski. The (non-releasable) connection device can be designed to be flexible and / or non-dimensionally stable. The (non-releasable) connecting device may be arranged (fixed) with a first end on a front side (facing away from the child) or back (facing the child) or underside of the catching element. Furthermore, the (non-releasable) connecting device with a second end to a seat portion of the child seat (preferably at a location to which a crotch strap is attached) may be attached. The (non-detachable) connection device can have additional functionalities, for example, by the (non-detachable) connection device in addition to the mechanical connection more

Connections be realized. These additional connections can

For example, electrical connections and / or connections to

Enabling gas flow. In particular, a control and / or gas supply of an airbag integrated in the catch body is possible in this manner.

In further embodiments, an actuating device may be provided for allowing a, in particular complete, detachment of the catching body.

The actuating device is preferably not accessible in an installed state of the child seat or arranged on a rear side and / or underside of the child seat. Alternatively or additionally, if the

Actuator allows release of the catcher body and the child seat is not installed and / or no child sitting in the child seat, installing the child seat or arranging the child in the child seat, in at least one

Configuration and / or orientation of the child seat, prevented (blocked), for example by the actuator by a handle, for. B. levers, is triggered, which is in this case in the way and / or in that the corresponding mechanism is triggered by the seat is guided closer to the backrest, in particular to the backrest is folded.

Furthermore, it may be provided that the actuating device allows (only) then (in particular complete) release of the catching body when the child's seat, in particular its headrest and / or side cheeks, is set to a size within a predetermined size range.

In general, the possibility of, in particular complete detachment of the catching body and / or the possibility of, in particular complete,

Montierens of the catcher to the size of the child, in particular a setting of a headrest and / or side cheeks to be coupled. Preferably, the catching body is (only) releasable when a predetermined minimum size is set (wherein the minimum size is greater than a minimum adjustable size). Alternatively or additionally, the catching body (only) can be mounted when a predetermined maximum size is set (the maximum size may be less than a maximum adjustable size). Minimum and maximum sizes may be identical or the minimum size may be less than the maximum size, preferably so that the catcher is freely detachably mountable in a height range, the height range preferably at most 25% and / or at least 5%, of the total, for height adjustment available area. More preferably, the height range includes an area suitable for children with a size of (approximately) 105 cm and / or a weight of (approximately) 15-18 kg.

Alternatively or additionally, the possibility for size adjustment of

Child seat, in particular a setting of a headrest and / or of

Side cheeks to be coupled with a mounting state of the catching body. In particular, a variable which is at or above a predetermined minimum size can be adjustable only with at least partially, in particular completely dissolved catching body and / or a size which is at or below one / of the predetermined minimum size, only at least partially fixed

Catcher be possible. Adjusting the size, in particular with regard to a headrest and / or with respect to side cheeks, may in particular involve adaptation of a distance and / or an angle (for example of the headrest and / or side cheeks) from / to a seat and / or a seat

Backrest to be understood.

One / the backrest may have at least one slot which preferably comprises two optionally (slightly) staggered straight portions and a (substantially perpendicular to the straight portions extending, in particular at least substantially horizontally extending) connecting portion. A headrest (s) preferably has at least one (specifically two) pin (s) that can move in the associated slot. The pin may preferably occupy (at least) two positions with respect to a direction perpendicular to the straight sections and / or perpendicular to an axis of symmetry of the headrest. Preferably, a transfer of the pins from one position to the other only in the region of the connecting portion is possible.

In particular, the transfer of the pin can be controlled either directly by (complete) detachment / disassembly (or at least partial, possibly complete) mounting of the catching body. Alternatively or additionally, a controller indirectly via a (in particular hidden, possibly open

accessible) mechanism, such as a button and / or switch and / or slide done. A concrete way of driving the pin may be a linkage.

When the head restraint is in its highest position, the pin may be outboard (displaced outward relative to an axis of symmetry of the head restraint) and transferring the pin to another position is not possible. When the headrest is in a middle position, the pin may (still) be outboard but inward translatable. When the headrest is in the middle position, the pin can (now) be placed inside (ie closer to

Be displaced symmetry axis of the headrest out, but (still) to the outside (away from the axis of symmetry) are shifted). When the headrest is in its lowermost position, the pin may be comparatively far inward (displaced in the direction of symmetry axis), with a transfer of the pin in the farther outward position is not possible. Also can be present between the positions shown, the headrest even more, lockable, headrest positions. Preferably, the headrest is lockable in said positions, which is not mandatory.

Depending on the embodiment, therefore, a transfer of the pins in different positions either possible or not possible. If now the transfer of the pin is coupled with a (complete) release or (at least partial) mounting of the catch body, this means that a (complete) release and / or (at least partial) mounting of the catch body is only possible if the pin can be transferred to the other position. Preferably, in this case, the mounted catching body should be assigned to the low positions of the headrest and the released catching body to the high positions.

A control over the positioning of side cheeks can be carried out analogously to (and / or together with) the control over the height of the headrest. Control over a height of the side cheeks may be by (at least substantially) vertical slots. Control over a width may be through (at least substantially) horizontal slots. A control over a height and width of the side cheeks can be realized by diagonal slots.

Pin and slot can also be reversed (so, for example, the pin on the

Backrest be arranged). The slot can be through another

Rail device to be replaced. The pin can be replaced by another

Sliding device to be replaced, z. B. by a projection and / or a rod and / or a roller. The sections of the slot may be reversed with respect to the arrangement further inside and further out.

In embodiments, an orientation of the child seat relative to a base and / or a vehicle seat may be variable. Preferably, the catching body is not detachable in any possible orientation, more preferably neither in a forward nor in a backward orientation. Alternatively or additionally, options for adjusting (or changing) the

Depend on orientation of a mounting state of the catch.

Alternatively or additionally, the child seat can be completely detachable from the base, wherein the catch body preferably (only) from the remote from the base Child seat is solvable and / or the child seat with mounted catcher is not mountable in the backward orientation on the base and / or the child seat is not mounted in the forward orientation on the base with unmounted catch body.

In concrete embodiments, a releasability of the catching body (only) in an entry or exit position (eg 90 ° twisted to the direction of travel)

be possible. Alternatively or additionally, starting from the entry or exit position with attached catch body only the forward orientation can be achieved. Alternatively or additionally, in the case of a non-attached catching body, starting from the entry or exit position, only the backward orientation can be achieved.

If the child seat comprises a base, wherein the child seat can be detached from the base and, for example, can be replaced in either a forward or a reverse orientation, a solvability of the

To be able to catch body of the main body (only) allows if the seat is detached from the base and / or may be possible with attached catch body starting from the dissolved from the base seat only in the forward direction and / or in non-fixed catch body starting from the Based dissolved seat a touchdown only in the reverse direction be possible.

Child seat and base can be rotated against each other (without the

Child seat must be completely removed from the base; of the

Child seat is therefore preferably rotatable on the base). The base may have a slot consisting of two curves (in particular semicircles)

composed, which are offset from each other (in particular from two

Semicircles with different radii). The two curves (semicircles) are connected together (at two connecting sections). The child seat has at least one pin, which can move in the slot or is guided therein and basically two different, with respect to a distance to a center of the semicircles or to a rotation axis, can take positions. Transfer of the pin from one position to the other is preferably possible only at the two locations (or in an area including these locations) at which the slot changes its radius (or at which the smaller semicircle ceases and the larger semicircle starts). These positions preferably correspond to entry and exit positions, in particular by 90 ° to possible use positions (in the direction of travel or opposite

Direction of travel) are twisted.

A transfer of the pins can preferably either directly through a

(Complete) loosening / disassembling or (at least partial) mounting of the catching body to be controlled. Alternatively, control may be indirectly via a (hidden or open) mechanism, such as a button or switch or slider. An option to drive the pin may be a linkage. Preferably, in this case, the mounted

Catcher of a forward orientation of the child seat and the dissolved

Be assigned Fangkörper a backward orientation of the child seat.

Pin and slot can also be reversed (ie, for example, the pin can be arranged on the base). The slot can be replaced by another rail device. The pin can be replaced by another slider, z. B. by a projection and / or a rod and / or a roller.

In embodiments, the child seat may be removed from the base and rotated 180 degrees (forward or backward orientation). The base preferably has at least one recess (recess) (specifically two recesses), so that with respect to the direction of travel

Asymmetry results. The child seat has on its underside at least one projecting element (concretely two protruding elements), which - assuming a suitable orientation - of the respective recess

can be included when the child seat is mounted on the base.

The (respective) protruding element can be moved in such a way that in a first position it attaches the child seat to the base in one

Forward direction allows and in a second position attaching the

Child seat allowed on the base in a reverse direction. A transfer can preferably be translational (alternatively or additionally rotatory, for example via a pivoting such as a toggle switch). A transfer of the (respective) protruding element can either directly by a (complete) loosening / disassembling or (at least partial)

Mount the catcher to be controlled. Or a controller can indirectly via a (hidden or open access) mechanism, such as a button or switch or slider done. A suitable option for driving the (respective) protruding element may include

Be linkage.

The recess (depression) and the protruding element can also be interchanged (that is to say, for example, the protruding element can be arranged on the base).

Alternatively or additionally, it is conceivable that instead of the above

Elementes the recess (recess) is movable (displaceable).

In the context of this invention, the term "child seat" is to be understood as a generic term for "classic" child car seats and baby car seats. Preferably, however, the child seat of this invention is a (classic) child seat (for larger children, eg group I / II and / or III child seat), which has a backrest structurally delimited by a seating area, the inclination of which is possibly can be varied over the seating area. The structural delimitation can be formed, for example, by a kink or the like. in the

However, in general (unless otherwise stated in the specific context) child seat always as a short notation for "child seat, z. In the context of this invention, features provided for a child seat are basically also applicable to a baby carrier and vice versa (unless otherwise stated) .The same applies to the term "child", which is also used as a generic term for children and Babies and toddlers is understood. So-called "baby shells" often comprise (only) a one-piece shell for accommodating the baby or child and may comprise a separate belt system, possibly a headrest and optionally further components Instead of a (structurally delimited) backrest, such "baby shells" have a back section which connects to a "seating area" where the child's buttocks can be taken up.

A child can be secured in a child seat by the three-point belt of the car or by a belt provided on the child seat itself (for example, a five-point belt, a chest belt, or the like). In this case, a belt over a shoulder of the child sitting in the direction of a be guided opposite basin side. But it can also be provided two straps, which are each guided over one of the shoulders.

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

An overall mechanism 10 (see FIGS. 1 to 3) allows attachment of a catching body (not shown in FIG. 1) to a main body at a first side (location) 100 and a second side (location) 200. On the first side 100 is a first locking device (first

Locking mechanism) 101 provided with a first locking device 102, comprising a first locking element 111 having a first pin 110 at one end and a first inclined surface 112 at the opposite end. The first pin 110 engages a first counter-structure 130 of the first locking device 102 (eg, recess or opening). The first locking element further comprises a projection which forms a first actuating device (first release mechanism) 113 and with which the first locking element 111 can be brought out of engagement with the first counter-structure 130 against the force of a first spring 114. The movement of the first locking element 111 (due to the operation of the first release mechanism 130) is blocked by a first blocking means 120 a third inclined surface 121, which is the first inclined surface 112 of the first locking element 111 (exactly) opposite and with this

Collaboration can be to allow movement of the first blocking means 120 in a direction perpendicular to the direction of movement of the first locking element 111 and against the force of a third spring 122.

The second side 200 has a basically nearly identical structure with the (only) difference that a (corresponding to the third spring 122) spring is associated with a second blocking means 220. Concretely, the second side 200 is a second locking device (second

Locking mechanism) 201, a second locking device 202, a second pin 210, a second locking element 211, a second inclined surface 212, a second actuating device (second release mechanism, eg button) 213, a second spring 214, a second locking means 220, and a second

Assigned to counterstructure 230. The enumerated in the previous sentence

Devices, means and / or elements are preferably like the

corresponding means, means and / or elements formed on the first side 100.

Because no spring is associated with the second blocking means 220, the second blocking means 220 is in a release position relative to the second locking element 211 (while the first blocking means 120 is in a blocking position with respect to the first locking element 111).

The two blocking means are connected via a first Bowden cable 11 and a second Bowden cable 12 (as examples of corresponding force transmitting means in general) which are attached to respective opposite sides of the blocking means 120, 220 so as to provide a transfer of the one (e.g. B. first) blocking agent from its blocking position in the

Release position transferred into a transfer of the other (eg second) blocking means from its release position to the blocking position. By the force of the third spring 122 is preferably the first blocking agent in its blocking position and the second blocking means in its release position. The Bowden cables 11, 12 may be deflected by rollers 13 in a suitable manner. The overall mechanism 10 may be completely integrated in the main body of the child seat except for the counter-structures 130, 230. The counter-structures 130, 230 may be part of the catching body and z. B. as belt tongues

be educated. The two release mechanisms 113, 213 may have a memory function (not shown). As a result, an actuation of the respective release mechanism 113, 213 remains so long (without further action from the outside) until the corresponding counter-structure 130, 230 after their

Removal from an appropriate receptacle (eg buckle) is reintroduced into this.

In the position of the overall mechanism 10 shown in FIG. 1, both sides 100, 200 are locked.

The overall mechanism 10 in FIG. 2 is identical to that of FIG. 1, but now the second actuator 213 is actuated such that the second pin 210 of the second locking member 211 is disengaged from the second counter-structure 230 against the force of the second spring 214 , It should be noted that the second locking element 211 now blocks the movement of the second blocking means 220 from its release position to the blocking position. Because of the two Bowden cables 11, 12 but also the transfer of the first blocking agent 120 is prevented from its blocking position in the release position, so that the first release mechanism 113 can not be operated.

2, the first side 100 is locked and the second side 200 is not locked.

The overall mechanism 10 in FIG. 3 is identical to that of FIG. 1, but now the first actuating device 113 is actuated such that the first pin 110 of the first locking element 111 is brought out of engagement with the first counter-structure 130 against the force of the first spring 114 , At the same time, the first blocking means 120 has been transferred against the force of the third spring 122 from its blocking position to its release position. Due to the connection of the blocking means 120, 220 through the Bowden cables 11, 12 and the second blocking means 220 has been transferred, from the release position in the

Blocking position. Thus, now blocks the first locking element 111, the movement of the first blocking means 120 from its release position in the Blocking position and thereby prevents the transfer of the second blocking means 220 from the blocking position back into the release position, so that now the second release mechanism 113 can not be operated.

In the position of the overall mechanism 10 shown in FIG. 3, the first side 100 is not locked and the second side 200 is locked.

4 and 5 show a child seat 50 having a main body 51 and a catching body 52, wherein the catching body 52 has a transverse portion 56 and a first (left) side portion 57 and a second (right) side portion 58. The catching body 52 furthermore receives a fastening belt 53 which is guided along the transversal section 56 and in each case has a belt tongue 54 on the first and second side sections 57, 58 of the catching body, which has a belt buckle 55 on the sides of the belt

Main body 51 can be engaged. The belt tongues may comprise the counter-structures 130, 230.

In the seat according to FIGS. 4 and 5, a detachability of the catching body in an entry and exit position and / or a rotatability (relative to a base 60) can be possible forward or backward. Furthermore, a backrest 61 or the entire seat with respect to his / her inclination can be adjusted.

6 and 7 show a child seat 50 with a main body 51 and a catch body 52 according to another embodiment. The catch body 52 analogously has a transverse section 56 and a first (left) side section 57 and a second (right) side section 58. The attachment of the catching body 52 is not explicitly shown (attachment can be done by means of a vehicle belt). The main body 51 includes a height-adjustable headrest 59.

In the seat according to FIGS. 6 and 7, a releasability of the catching body in

Depending on the headrest position allows his. Even if the concrete seat is possibly usable only in the forward direction, a coupling of the alignment to the attachment of the catching body would also be conceivable. FIGS. 8-11 show schematic sections of a device according to the invention

Child seat in different configurations. The solid lines indicate a headrest 59 and the dashed lines a backrest 61 of the child seat. Headrest 59 and backrest 61 are mutually movable (movable). The backrest 61 has two slits 62, each composed of two (slightly) staggered straight sections 63, 64 and a (substantially perpendicular to the straight sections 63, 64 extending, in particular at least substantially horizontally extending) connecting portion 65 composed. The headrest 59 has two pins 66, which can move in a respective associated slot 62 and are guided in this. Pin 66 may occupy (at least) two positions with respect to a direction perpendicular to straight sections 63, 64, or perpendicular to an axis of symmetry of headrest 59 (a first position being shown in FIGS. 8 and 9, and a second position in FIG Figs. 10 and 11 is shown).

From Fig. 8-11 it can be seen that a transfer of the pin 66 from one position to the other only in the region of the connecting portion 65 is possible.

The transfer of the pin 66 can be controlled either directly by (complete) detachment / disassembly (or at least partial, possibly complete) mounting of the catching body (not shown in FIGS. 8-11). Alternatively or additionally, a control indirectly via a (in particular hidden, possibly openly accessible) mechanism, such as a button and / or switch and / or slide done. A concrete way to drive the pin 66 may be a linkage.

Fig. 8 shows concretely the headrest 59 in its highest position. For this purpose, the respective pin 66 must be outside (displaced outward with respect to an axis of symmetry of the headrest), whereby a transfer of the respective pin to another position is not possible. In Fig. 9, the headrest 59 is in a middle position with the respective pin 66 (still) out, but inside

is convertible. Fig. 10 shows the headrest in the middle position shown in FIG.

9, wherein the respective pin 66 (now) is arranged inside (ie closer to

Is displaced towards the symmetry axis of the headrest, but (still) outside (away from the axis of symmetry) can be moved). In Fig. 11, the headrest is in its lowermost position. For this, the respective pin 66 has comparatively far be inside (in the direction of symmetry axis shifted), with a transfer of the pin 66 in the farther outward position (according to FIG. 8 or 9) is not possible.

Likewise, there may be further, lockable, headrest positions between the shown positions of the headrest 59. Preferably, the headrest in the positions shown can be locked, which is not mandatory.

Depending on the embodiment, a transfer of the respective pins into different positions is either possible or not possible. If now the transfer of the pin is coupled with a (complete) release or (at least partial) mounting of the catch body, this means that a (complete) release and / or (at least partial) mounting of the catch body is only possible if the pin can be transferred to the other position.

A control over the positioning of side cheeks can be done analogous to the control of the height of the headrest 59. A control over a height of the side cheeks by (at least substantially) vertical

Slots take place. Control over a width may be through (at least substantially) horizontal slots. A control over a height and width of the side cheeks can be realized by diagonal slots.

In Fig. 12-15 is another embodiment of an inventive

Child seat fragmentary and shown schematically, in four different configurations. In solid lines, a bottom 67 of a child seat is shown, and in dashed lines, a top 68 of a corresponding base 60. Child seat 50 and base 60 are rotatable against each other (without the child seat 50 must be necessarily removed from the base 60, so the child seat is preferably rotatable on the base 60). The base 60 has a slot 69 which is composed of two semicircles, the

are offset from each other or have different radii. The two semicircles are interconnected (at two connecting sections). The child seat 50 has a pin 70 that can move in the slot 69 and is guided in this and basically two different, with respect to a distance to a center of the semicircles or to a rotation axis, can take positions.

From Fig. 12-15 it can be seen that a transfer of the pin 70 from one position to the other is possible only at the two points at which the slot 69 changes its radius (or where the smaller semicircle stops and the larger semicircle starts). These positions correspond to entry and exit positions that are 90 ° to possible use positions (in

Direction of travel or against the direction of travel) are twisted. In Figs. 12 and 15, the two preferred use positions (forward and backward aligned) are shown.

In each case 90 ° positions are shown in FIGS. 13 and 14, wherein the pin is set once to the larger semicircle and once to the smaller semicircle (radius). A transfer of the pin 77 can either be controlled directly by (complete) detachment / disassembly or (at least partial) mounting of the catching body. Alternatively, control may be indirectly via a (hidden or open) mechanism, such as a button or switch or slider. An option to drive the pin 70 may be a linkage.

In Fig. 16 is another embodiment of an inventive

Child seat is shown in fragmentary and schematic, with a bottom 67 of the child seat 50 in solid lines, and a top 68 of the base 60 are shown in dashed lines, the child seat 50 can be taken from the base 60 and rotated by 180 ° can be replaced (forward - or backward orientation).

The base 60 has two recesses (depressions) 71 in such a way that an asymmetry results with respect to the direction of travel. The child seat 50 has on its underside 67 two protruding elements 72, the - a matching

Orientation provided - can be absorbed by the respective recess 71 when the child seat 50 is mounted on the base 60. The protruding member 72 may be moved so as to allow the child seat 50 to be mounted on the base 60 in a forward direction in a first position and to be attached in a second position Child seat 50 on the base 60 in a reverse direction allowed. A

Transfer may preferably be translational (alternatively or additionally rotatory, for example via a pivoting such as a toggle switch). A transfer of the (respective) projecting element 72 can either directly by a (complete) detachment / disassembly or

controlled (at least partial) mounting of the catching body; or a controller can be indirectly via a (hidden or open access) mechanism, such as a button or switch or slide done. A suitable option for driving the (respective) projecting element 72 may be a linkage.

An interaction with the solution shown in FIGS. 1-3 may, for example, be such that (at least) one of the deflection rollers 13 is displaced or displaceable by a change in orientation or configuration, so that the Bowden cables must travel less and both sides of the Catcher can be solved simultaneously.

Alternatively, an exchange of pin and slot or recess and projection element is possibly conceivable in the respective examples. Alternatively or additionally, it is conceivable that instead of the above element the

Recess (recess) is displaceable.

Figs. 17-20 show a high-schematic and sectional view of a child seat, comprising a main body 51 and a catching body 52, wherein the

Catch body 52 has (at least) a fastening belt 53 with two belt tongues 54, which with (each) a buckle 55 on the main body 51st

Cooperation. In particular, between the two belt locks 55, a coupling device 74 or clip (specifically designed as a rod) is arranged, which can assume two positions. In a first position, the one (in Fig. 17, left) Gurtzunge 54 in operative connection (cooperation,

in particular engagement) with the associated belt buckle 55. In a second position, the other belt tongue 54 (in Fig. 17, the right belt tongue) in

Operative connection (cooperation, in particular engagement) with the corresponding belt lock 55. The belt tongues 54 may each have a recess (hole). The switching of the coupling device 74 (clamp) from the first to the second position (or back) is (only) possible if both belt tongues 54 interact with the respective belt locks 55. For switching, the child seat on a (manually operated) mechanism, such as a switch or knob or slider, with a concrete rotary switch (as in Fig. 17) may be provided.

Furthermore, each buckle 55 may have an unlocking mechanism by means of the belt tongue 54 and buckle 55 can be solved from each other. The unlocking mechanism may be a push button (or other manually operated device), which may be colored red, if necessary. In order to avoid that a user understands the red signal color on the locked side as a request for release (wherein a release may possibly be prevented anyway), a cover for the unlocking mechanism of the locked side can be provided, which are placed (manually) can or automatically when the rotary switch is pressed. In the case of an automatic cover, the unlocking mechanism (unlocking button or pushbutton) on the opposite side can optionally be made accessible again at the same time (if necessary).

also automatically).

In Fig. 19 and 20 is still shown that each buckle 55 has a locking device 75 (blocking element), which is an intrusion of the

corresponding end of the coupling device 74 in a receiving space of the buckle 55 (for cooperation with the recess / the hole of the belt tongue 54) used, so that no belt tongue 54 is located in the buckle 55.

This locking device 75 may possibly be moved away (for example displaced or twisted) by penetration of the belt tongue 54 into the receiving space of the belt lock 55, so that a path for the end of the coupling device 74 is released. The locking device 75 may be spring-loaded and / or when removing the belt tongue 54 from the buckle 55 back into the locking division.

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.
