Patent Description:
The invention further relates to a safety part suitable for a child seat transporting system.

A known child seat transporting system of Team Tex called Satellite Isofix Car Seat Group o+ comprises a base to be connected by means of Isofix connectors to a vehicle seat. On said base an outer seat can be mounted, whereas an inner child seat can be connected to the outer seat. Such base is known from <CIT>, whilst such outer seat and inner seat are known from <CIT>. The inner seat can directly be mounted on a frame of a stroller.

A disadvantage of such a child seat transporting system is that the outer seat is rather bulky and can, due to its size, only be used as an intermediate structure between the inner seat and the base.

Furthermore, since the inner seat is directly mounted on the frame of the stroller, the width of the inner seat must be so large that its longitudinal sides can be connected to supporting elements on the sides of the frame of the stroller. Due to this width the inner side is relative large and heavy to be carried by a person from the base inside a vehicle to the frame of the stroller or to some other location.

<CIT> shows a lightweight carrier with a handle which can be attached to a a car seat. <CIT> shows a maxi cosi type seat which can be attached to a car seat via a base or to a frame of a stroller.

At least one of the objects of the invention is to provide a child seat transporting system whereby the child seat can easily be carries around whilst still being suitable to be used in a vehicle and on a frame of a stroller.

This object is accomplished with the child seat transporting system with the features of claim <NUM> according to the invention in that the safety part, when disconnected from the the base, is detachably connectable to a frame of a stroller, whereby when the safety part with the child seat connected thereto is connected to the frame of the stroller, the child seat is detachable from the safety part, which child seat comprises two protrusions at a rear side of a back portion thereof for resting on a flat surface when used without the safety part, whilst when used with the safety part the protrusions of the child seat are inserted into blind holes of the safety part to position the child seat in the safety part and to prevent the child seat to be able to tilt with respect to the safety part.

Since the width of the safety part will be so large that its longitudinal sides can be connected to supporting elements on the sides of the frame of the stroller, the width of the child seat connected to safety part can and will be smaller than by the known inner seat of <CIT>.

By the child seat transporting system according to the invention the safety part is used as intermediate part between the child seat and the vehicle seat, as well as intermediate part between the child seat and the frame of the stroller.

When transporting the child seat outside the vehicle and outside the stroller, the child seat can be carried alone or connected to the safety part. If carried alone, the child seat is relative light, compact and can easily be carried around, wherein the child can still maintain the same position in the child seat and does not need to be woken up. If a more sturdy construction around the child seat is desired, the child seat connected to the safety part can carried around. The child seat only needs to provide a comfortable seating part for a child, whilst safety provisions required by regulations for use of the child seat in a vehicle or in a stroller will be provided by the safety part. Another advantage of having a safety part and a child seat is that extra functionalities can be put into the safety part, like active cooling or electronic communication, that might be heavy and bulky.

Preferably the handle <NUM> is first pivoted in a direction as indicated by arrow P1 about pivot axis <NUM> to provide more space for the removal of the child seat <NUM>. The use of only the child seat <NUM> to transport a child located therein and being hold by means of the harness has the advantage that a user only needs to carry the relatively light weighted child seat <NUM> and the child, whereas the heavier and more sturdy safety part <NUM> can remain on the frame <NUM> of the stroller <NUM>.

<FIG> show different views of the child seat <NUM>. The child seat <NUM> comprises a shell <NUM> made of plastic such as polypropylene (PP). The same material can be used for the safety part <NUM>. However the wall thickness of the child seat <NUM> will be less than the wall thickness of the safety part <NUM>. At a rear side of the back portion <NUM> the child seat <NUM> comprises two protrusions <NUM>. The protrusions <NUM> can be inserted into blind holes <NUM> of the safety part <NUM> to position the child seat <NUM> in the safety part <NUM> and to prevent the child seat <NUM> to be able to tilt with respect to the safety part <NUM>.

The weight of the child seat <NUM> is about <NUM> kilogram, the weight of the safety part <NUM> is about <NUM>,<NUM> kilogram, so the weight of the unit <NUM> is about <NUM>,<NUM> kilogram. Both the child seat <NUM> and the safety part <NUM> are preferably covered with a textile.

The safety part <NUM> comprises a ring shaped frame <NUM> extending around the upper side of the safety part <NUM>. The ring shaped frame <NUM> prevents the safety part <NUM> and therefor the child seat <NUM> when located inside the safety part <NUM> to be deformed in case of a crash like a car incident. The safety part <NUM> is provided with two enlarged passages <NUM> to reduce the weight of the safety part <NUM>.

Due to the safety part <NUM>, the unit <NUM> comprising the safety part <NUM> and the child seat <NUM> fulfills the requirements regarding safety.

The safety part <NUM> comprises a bottom part <NUM> to support the child seat <NUM>. The blind holes <NUM> are located on both sides of the bottom part <NUM>. The safety part <NUM> is near a front side thereof provided with two recesses <NUM> through which the pen <NUM> of the child seat <NUM> can be connected to two first hooks of the coupling mechanism according to the present invention, as will be explained here below.

<FIG> show a first embodiment of the coupling mechanism <NUM> according to the present invention.

The coupling mechanism <NUM> comprises two coupling elements <NUM> each provided with the first hook <NUM> and a second hook <NUM>. The coupling elements <NUM> are pivotable about pivot axes <NUM>. Part of the coupling mechanism <NUM> is also pen <NUM> of the child seat <NUM> as well as pen <NUM> of the safety part <NUM> by means of which the safety part <NUM> can be connected to the base <NUM>. The pen <NUM> cooperates with first hooks <NUM> whilst the pen <NUM> cooperates with second hooks <NUM>.

As can be seen in <FIG> pen <NUM>, pen <NUM> and axes <NUM> extend parallel to each other.

Each coupling element <NUM> is also provided with a third hook <NUM>. The third hook <NUM> is attached to a spring <NUM>. The spring <NUM> is attached at an end remote of the third hook <NUM> to an operating device <NUM>.

In the <FIG>, <FIG> the coupling elements <NUM> are in a first position wherein the pen <NUM> of the child seat <NUM> is disconnected from the first hooks <NUM> and the child seat <NUM> and safety part <NUM> can be decoupled from each other. In the first position pen <NUM> of the safety part <NUM> is also is disconnected from the second hooks <NUM>.

Each coupling elements <NUM> comprises an abutment surface <NUM>. Each first hook <NUM> comprises a notch <NUM> and a gripping surface <NUM>. Each second hook <NUM> comprises a notch <NUM> and a gripping surface <NUM>. In the first position the abutment surfaces <NUM> are located in the recesses <NUM> whilst the notches <NUM> and the gripping surfaces <NUM> on the first hook <NUM> are located outside the recesses <NUM>.

Each coupling elements <NUM> also comprises a locking surface <NUM>.

When positioning the child seat <NUM> on the safety part <NUM> the protrusions <NUM> of the child seat <NUM> are inserted into the blind holes <NUM> of the safety part <NUM> and the pen <NUM> of the child seat <NUM> is brought into the recesses <NUM> and is pressed with a pressing force against the abutment surfaces <NUM> of the coupling elements <NUM>. Due to this pressing force, the coupling elements <NUM> are being pivoted about the pivot axes <NUM> against spring force of the springs <NUM> in a direction indicated by arrow P2 to a second position. In the second position, as shown in <FIG>, the pen <NUM> of the child seat <NUM> is located in the notches <NUM> of the first hooks <NUM> and engaged to the safety part <NUM> by means of the first hooks <NUM> and the gripping surfaces <NUM> thereof, whilst the pen <NUM> of the safety part <NUM> is located in the notches <NUM> of the second hooks <NUM>. In this second position the pen <NUM> of the child seat <NUM> is directly coupled via the coupling elements <NUM> to the pen <NUM> of the safety part <NUM>. In case that the safety part <NUM> is coupled by means of the pen <NUM> to the base <NUM>, the child seat <NUM> is directly coupled via the coupling elements <NUM> to the pen <NUM> of the safety part <NUM> and to the base <NUM>. Preferably the pens <NUM>, <NUM> and the coupling elements <NUM> are made of a strong material like metal so that relatively large forces can easily and efficient be transmitted from the pen <NUM> to the pen <NUM> and to the base <NUM>. Preferably the crotch belt <NUM> is connected to the pen <NUM>. When the unit <NUM> is mounted on the base <NUM> forces on the harness <NUM>, for example in case of a crash, will be transmitted via the crotch belt <NUM>, the pen <NUM>, the coupling elements <NUM> and the pen <NUM> directly to the base <NUM>. This has the advantage that the other parts of the child seat <NUM> can be less strong, which provides a great degree of freedom of design.

In <FIG> the coupling elements <NUM> pivot in a clockwise direction from the first to the second position.

In the second position the locking surfaces <NUM> of the coupling elements <NUM> are brought in contact with locking surface <NUM> on the operating device <NUM> to lock the coupling elements <NUM> and the hooks <NUM>, <NUM> thereof in said second position.

To unlock the locking surfaces <NUM>, <NUM> the operating device <NUM> is being pivoted about pivot axis <NUM> against spring force of springs <NUM> in a direction as indicated by arrow P3, whereby under spring force of the springs <NUM> the coupling elements <NUM> are being pivoted in a direction opposite to arrow P2. When pivoting the coupling elements <NUM> in a direction opposite to arrow P2, abutment surfaces <NUM> of the coupling elements <NUM> pushes the pen <NUM> slightly out of the notches <NUM>, whereafter still under spring force of the springs <NUM> the coupling elements <NUM> pivot to the first position.

As can be see in <FIG> an angle A between a first virtual line <NUM> between the first pen <NUM> of the child seat <NUM> and the pivot axis <NUM> and a second virtual line <NUM> between the second pen <NUM> of the safety part <NUM> and the pivot axis <NUM> is for example <NUM> degrees degrees. An angle B between the first virtual line <NUM> horizontal H is for example between <NUM> and <NUM> degrees, so for example <NUM> degrees. As long as the angle B is less than <NUM> degrees, preferably less than <NUM> degrees and more preferably less than <NUM> degrees, the movement of pen <NUM> in vertical direction along the vertical V towards and against the abutment surfaces <NUM> will cause pivoting of the coupling elements <NUM> in the direction indicated by arrow P2. The angle A as well as the distance between the first pen <NUM> of the child seat <NUM> and the pivot axis <NUM> determines the force needed to pivot the coupling elements <NUM>. The pivoting is independent of the location and distance of the pen <NUM> with respect to the pivot axis <NUM>. As can be seen in <FIG> the pen <NUM> is located almost exactly vertical above the pen <NUM>. Due to the coupling elements <NUM> comprising the first and second hooks <NUM>, 74a freedom to determine the locations of the pens <NUM>, <NUM> and axis <NUM> is obtained, whilst still a direct transmission of the forces from the pen <NUM> via coupling element <NUM> to pen <NUM> is obtained.

<FIG> show a second embodiment of a coupling element <NUM> of a coupling mechanism according to the invention.

The coupling element <NUM> differs from the coupling element <NUM> in that it comprises a slotted hole <NUM> in which the pen <NUM> is located. A part of a wall <NUM> bounding the slotted hole <NUM> forms the second hook.

In <FIG> the pen <NUM> is located against a first end <NUM> of the slotted hole <NUM>. This position defines the first position of the coupling element <NUM>.

In <FIG> the pen <NUM> is located against a second end <NUM> of the slotted hole <NUM>. This position defines the second position of the coupling element <NUM>.

<FIG> is a perspective view of a person <NUM> carrying a unit <NUM> comprising a safety part <NUM> and a child seat <NUM> connected thereto with a hand <NUM>. A child <NUM> is present in the child seat <NUM>. As can be seen also in <FIG>, the part <NUM> of the handle <NUM> extends perpendicular to the walking direction of the person. Safety part <NUM> and thus unit <NUM> has a width W1.

<FIG> is a perspective view of a person <NUM> carrying a child seat <NUM> by its handles <NUM> with a hand <NUM>. The weight of the child seat <NUM> to be carried is less than the weight of the unit <NUM>. Furthermore, the child seat <NUM> has in a direction perpendicular to the walking direction of the person a width W2 being smaller than the width W1 of unit <NUM> so that the child seat <NUM> can be held closer to the body of the person <NUM>. This also makes it easier to carry the child seat <NUM>. The difference can also easily be seen from the <FIG> showing respectively a rear view of a person carrying the unit <NUM> respectively a child seat <NUM>. Also the orientation of the hand <NUM> is different. To carry the unit <NUM> the person must turn its wrist to be able to place its hand <NUM> on part <NUM> of the handle <NUM>. To carry only the child seat <NUM> the person <NUM> can held its arm <NUM> almost flat along its body and does not need to turn its wrist.

<FIG> is a perspective view of a person carrying a child seat <NUM> by its arm <NUM>. Due to the flexible handles <NUM> and the orientation thereof, the child seat <NUM> can also be easily carried close to its body on the persons arm <NUM>.

The child seat transporting system <NUM> according to the invention has the advantage that the child can be transported in a number of different manners which can each time be chosen depending on the wishes of the person taking care of the child.

It is also possible to use in other embodiments the coupling mechanism to couple the safety part to the base, to couple the child seat directly to the base or to couple other components to each other. In case that the child seat will be directly coupled to the base, the child seat must fulfil the required safety regulations.

It is also possible to connect the child seat <NUM> with other means to the safety part <NUM>.

By the embodiment as shown in <FIG> the coupling mechanism comprises two coupling elements. However, it is also possible to use only one or more than two coupling elements.

It is also possible that the safety part comprises ISOFIX-connectors so it can be directly connected to the vehicle seat without a vehicle belt.
