Description

Background of the invention

To improve child safety when carrying children in an automobile, it is advisable to provide a child seat if the child being carried along is too small to use normal three-point harness or seat belts. Typical child seats are provided as separate seats which can be attached to the automobile and which are suitably sized and shaped to hold small children in a secure manner. Typical child seats have a variety of designs, some of which are intended for attachment to the rear seat or the front seat of an automobile, or indeed for both. In addition, child seat designs include forward and rearward designs, which direction is determined by the forward and reverse directions in the automobile.

Many child seat designs include a three or four-point harness used to hold the baby or child in the seat. Other designs also include a lap pad or retainer positioned over the child's lap or stomach when in the seat to securely hold the child in the seat and support the child in the event of an accident. It is typical for these lap cushions or restraints to be connected to the standard seat belts provided in the automobile, the lap support being provided with a groove or the like so that the seat belt in the automobile can be positioned in front of the lap retainer and thus hold it in place. This system improves the safety of the child since both the child seat harness and the seat belt, both attached to the automobile, are used to secure the child in the event of an accident.

Current child seat designs are typically provided in one or the other of the forward or backward orientation. That is, most child seats are provided with either a forward or backward design, thereby limiting the choice for the child, thereby limiting the possibility of allowing the child to view the front or rear of the car as it does Like child. In addition, integrating the child seat with the seat belt positioned in the automobile, either with or without the help of the lap support or cushion, further prevents the ability to adjust the orientation and location of the child seat. After all, many child seats are in a fixed orientation and can not be tilted forward or backward. This reduction in tilting capabilities of the child seat is further limited by using the seat belt of the automobile to secure the child seat in the automobile.

In addition, there are real problems with child seat misuse where the child seat is not properly connected to the automobile or is not used the same way the seat was intended. This is especially a problem when the child seat is to be connected to the automobile by means of the built-in seat belts. In addition, if the child seat has multiple possible orientations or different mounting positions, the possibility of user error increases greatly. Unfortunately, the safety function of a child seat is dramatically compromised if it is not properly attached or properly constructed.

Outline of the invention

The present disclosure has been drafted to address the above problems. In particular, it is an object to provide a child seat that can not be misused or mismatched with the automobile. Also, a child seat, which can be rotated and tilted as possible in a direct and controllable manner, and which does not specifically requires the three-point or Zweitunktgurtzeug or a seat belt, which is usually present on the car to hold the child seat in position. The present invention provides a child seat according to independent claim 1. Further preferred embodiments are specified in the dependent claims.

The claimed invention may be better understood in view of the embodiments described below. The described embodiments generally describe preferred embodiments of the invention. The attentive reader will note that some aspects of the described embodiments are beyond the scope of the claims. In view of the fact that the described embodiments in fact exceed the scope of the claims, the described embodiments are to be considered as supplementary background information and not as definitions of the invention per se. This also applies to the following "Brief description of the drawings" and the "Detailed description".

The child seat of the present disclosure is one which preferably interacts with an automobile to provide a secure lock for a child while also allowing the seat to rotate freely to allow for front or rearward alignment of the seat. In particular, the child seat is provided with a base or piece having corresponding Isofix connectors for attachment to the automobile. Isofix connectors are well-known in the automotive fastener field, and provide the automobile with a particular belt support point to provide sufficiently strong and secure connections to the frame or chassis of the automobile. Such Isofix connectors are also installed in new cars, or can easily be retrofitted to new cars to provide secure rigid connections with the automobile.

The child seat of the present disclosure is intended to be connected by means of such an Isofix connector assembly, and is provided with the corresponding connector modules in the base. The base piece is therefore arranged and designed to provide the base of the child seat, and will sit or be positioned on the seat of the automobile to which the child seat is attached. When the base is positioned on the seat, the Isofix connectors can be connected to those positioned in the automobile, thereby securely and securely attaching the base to the automobile.

The child seat comprises a seat part and this seat part is connected to, or connectable with, or integrally formed with the base piece described above. In this way, the seat part is directly connected to the automobile via the Isofix connectors, either via the base piece or actually directly. In addition, the child seat may be provided with a seat belt or belt inside the seat part. The seat belt or belt may be in direct connection with the base piece so that the belt is basically directly connected to the automobile by means of the Isofix connectors. The advantage of using the Isofix connectors is that the belt inside the child seat is connected to the automobile without using a system which makes any provision, for example by using one of the built-in two- or three-point harnesses of the automobile. Should the child seat be equipped with a separate base piece to which the seat portion is attachable or secured, the belt is secured in such a manner that it is directly connected to the base piece, perhaps by some heavy-duty connection means, so that the belt in the seat portion is still provided with a direct connection path through the Isofix connector.

It is possible that the child seat is designed as a rear-facing child seat. When the child seat is a rear-facing child seat, the Isofix connectors are provided in either the seat portion or base toward the front of the seat. The front of the seat is that part of the child seat that lies next to the child's legs and feet when the child is in the seat. In this situation, the strap may be provided as a first strap, preferably as a seat belt loop. The seat belt loop may be connected to or connected to the base piece at the front of the child seat, either when the base piece is integral with or separate from the seat portion. The belt loop may then form the seat portion around the top of the seat so as to form a loop which extends around the back of the headrest from the seat portion and back of the child and back to the point of connection with the Isofix connectors. In this manner, when the automobile is involved in an accident and the head portion of the seat portion is under extreme load, the seat belt or belt loop will absorb the majority of the forces and prevent the seat from deforming due to the weight of the child therein. Furthermore, the majority of forces are routed directly through the child seat to the Isofix connectors and to the automobile.

If the child seat is designed as a forward-facing child seat, Isofix connectors are provided on the rear of the child seat, which is the side closest to the child's back when the child is seated in the seat. The strap may be provided as a strap, which in turn is in direct communication with the Isofix connectors as described above, but which has either the female or male parts of a normal seat belt connector at the ends of the strap. The specific structure therefore allows to provide a lap connector, which will be described in more detail below, which connects to the plug and / or the socket of the seat belt connector provided on each side of this seat belt or belt, and thus a direct connection path of this lap holding device, which is positioned in front of the child towards the body of the car via Isofix connector.

It is also possible to provide a child seat with both front and rear Isofix connectors and both with the belt systems described above. Such a child seat would be directly connectable to an automobile via Isofix connectors, thus allowing the child to be positioned in a forward or backward orientation.

On the base piece a rotatable element is attached or fastened. This rotatable member connects to the base in a rotatable manner so that the rotatable member can be rotatably aligned with respect to the base when necessary. Attached or attachable to the rotatable element, or integral with the rotatable element Element is a seat part. The seat portion provides the seat in which the child is placed to take away during transport. The seat part only adjoins or is only attachable to the rotatable element or piece, and thus can be rotated freely with respect to the base piece. That is, the base is attached to the automobile in a known orientation, and the seat is rotatably supported by the rotating means or rotatable member.

In the rotatable child seat, a first seat belt may be provided. This first seat belt is attached or attachable to the rotatable member. This seat belt is thus suitably secured by the rotatable member to the base and then by the Isofix connectors. That is, the first seat belt is provided with a direct connection path to the Isofix connectors, and thus is suitably and securely connected to the automobile by such Isofix connectors. In this manner, the first seat belt is suitably provided and structured to provide a secure connection to the automobile.

It is preferred if the first seat belt is provided with the plug or socket parts of a seat belt connector. In particular, each end of the seat belt may be so provided with the plug or socket of a seat belt connector, and in fact the ends may be provided with different types of plug or socket. In such a design, the first seat belt in the seat portion of the child seat is arranged and held, wherein the connector parts are accessible from the outside of the child seat and can be easily reached by a user of the child seat.

The child seat may also be provided with a lap cushion, front cushion or retainer for securing the child in the seat portion. In particular, the front or lap cushion is intended to form a bridge between one side of the seat part and the other, so that the child is securely held in the seat. In order to connect the lap cushion to the seat part, it is preferable to provide this with a corresponding connector or socket of a seat belt connector. Thus, it is clear that the child can be positioned in the seat, that the lap restraint or cushion can be positioned over the child, especially aligned with the child's lap or stomach, and then the lap cushion connected to the child seat by the connectors thereon which can be connected to the connectors of the first seat belt. Thus, it is obvious that then the first seat belt will completely bridge the gap between each side of the child seat through the lap cushion, thus providing a corresponding seat belt loop around the child. It is further clear that both the first seat belt and the lap cushion are provided with a direct connection to the Isofix connectors, which thus connect both elements to the body of the automobile. An essential element of this design is that the lap cushion is properly connected to the body of the automobile in a secure manner through the child seat. With such a connection, therefore, it is not necessary to use one of the seat belts or harnesses fastened with the automobile, and therefore the child seat and the lap restraint or cushion can be used without the necessity of using one or more of the safety harnesses or seat belts. By this aspect, the rotational ability of the child seat is supported.

It is further preferred to provide a child seat with a second seat belt. Again, the second seat belt should be connected or connectable to the rotatable member so that it is provided by the Isofix connectors with a direct connection to the automobile. This second seat belt is preferably held within the seat portion of the child seat, and is attachable to the rotatable member on the front leg portion of the seat portion. The second seat belt forms a loop from its front-side connected piece, or connectable piece, around the upper edge of the child seat around the rearward end of the child seat. As apparent from this structure, when the child seat is directed rearward and a frontal impact occurs, the upper head of the child seat is provided with a direct connection to the Isofix connectors of the automobile. Further, by providing the seat belt loop connected to the rotatable member, the longitudinal deformation of the child seat is contained and reduced in such an impact, which means that the child seat does not deform and the child's safety is drastically increased.

It is also preferred if the first and second seat belts are connected or connectable so that a cradle or corresponding cage of seat belts is formed or provided around the child when in the seat.

There are a variety of mechanisms for holding the rotating or rotatable member to the base. One possibility is simply to provide the base piece with a post or pin which provides a larger diameter head. The shaft of the post is positioned by a corresponding hole on the rotatable member whereby the rotatable member can rotate relative to the base, but the rotatable member is prevented from disengaging from the post. That is, the head bigger Diameter on the support is provided with a larger piece than the extension of the hole in the rotatable member, whereby it is ensured that when the pieces are connected to each other, the rotatable member with respect to the base piece can rotate, but not solved can be.

A particular design variant for the rotating or rotatable element is that of a disc having a central opening for securing the base, preferably as described above. The central opening can receive the shaft of the support, wherein the opening does not allow the head of larger diameter to pass, so that after connection of the disc and the support, the two are rotatably held together. Furthermore, the disc element may be provided with a second opening, preferably with a circumferential groove or track to the edge of the disc element. This circumferential groove may extend in any degree around the edge of the disk element, with a 180 ° or 360 ° possibility being desirable. The circumferential groove or track is provided for cooperation with a second attachment means of the base member so that the groove allows the rotating or rotatable member, or disc member, to rotate about the central hole or opening while the second attachment means are from the base piece held in the groove. That is, the disk member rotates about the central post provided on the base piece. The second attachment means, which may consist of a number of one or more, are positioned within the circumferential groove and thus permit rotation of the disc member. Again, the design variant for the second attachment means is the same as the support described above in the center of the base.

It is possible to provide the disk element of a first central disk element and a second annular or toroidal element. The second annular member has an inner diameter larger than the outer diameter of the central disc member, and thus, when the two are disposed together in the rotatable member, the gap between the outer diameter of the inner disc and the inner diameter of the outer ring is circumferential Groove or track provides. This two-piece design of the disc member allows easy production of the groove for receiving the second attachment means from the base.

In order to form a single rotatable element from the central disk part and the outer ring element, they can be connected to each other by means of disk fastening means. These washer attaching means may be of any shape, the requirement being that they should not overlap with the passage of the second fastener from the base when passing around the circumferential groove or track. Perhaps through a U-shaped bracket which allows sufficient clearance for the larger diameter head on the second fastener, the inner disk part and outer ring part may be respectively secured together to provide the disk element. A preferred possibility is when the disc attachment means is also the means by which the first and second seat belts are attached to the rotatable member.

While the disk element may be structured as a flat disk or as a flat central disk with a flat outer ring, it is also possible to provide this by a three-dimensionally curved element. That is, the disk member or rotatable member is provided as a portion from the outer surface of a ball. When the disc member is made of a two-piece variant, the outer ring member is structured to mate with the curved profile of the central disc member so as to provide a suitably curved structure of the entire rotatable member.

It is also possible to provide the rotatable child seat so that it can be tilted forward and backward in certain directions of rotation. In particular, it is desirable for the child seat to be able to tilt fore and aft when in each of the front and rear orientations with respect to the direction of movement of the car. The swivel seat of the present disclosure may be tilted when provided with the lap restraining device connected to the first seat belt connected directly to the Isofix connector. With this structure, the seat belt of the automobile does not need to engage the child seat, and thereby the child seat is free to rotate as well as tilt as required.

To allow the child seat to tilt forward and backward, the rotatable member, or disc member, is provided with grooves extending from the circumferential groove or track on the edge of the disc member. It will be appreciated that if the circumferential groove is provided with these groove extensions approximately diametrically opposite each other, the seat can be tilted back if the second attachment means of the base piece can be disposed within these grooves. The grooves on one side of the circumferential groove generally extend away from the center of the disk element, and the grooves on the other side extend toward the center of the disk member so that the grooves are all aligned and parallel to each other, it is clear that when the child seat is rotationally aligned so that these aligned grooves are close to the disk second attachment means of the base piece, the seat with the up and down and along the aligned tracks or grooves extending second attachment means can be tilted forward and backward. To improve this, the central opening in the central disc-like part can also be provided with an aligned longitudinal groove, so that in any orientation of the child seat forward or backward, the seat part can be tilted with respect to the base piece, by sliding of the rotary member so that the second attachment means and the central support move up and down the aligned grooves in the disc member.

Detailed description

1 shows two views of a child seat 1 according to the present invention. In 1A is the child seat 1 positioned in a forward orientation with the child using the seat in the normal direction of travel of the automobile 2 would sit. In 1B is the rotatable child seat 1 in a rearward orientation so that the child would see the rear of the automobile. As can be understood from these figures, is the rotatable child seat 1 provided with a number of elements that make up its construction. In particular, at the bottom of the rotatable child seat 1 a basic piece 10 intended. The basic piece 10 should on the seats of the automobile 2 rest in which the child seat 1 to be installed. As can be seen from all figures, the base piece 10 a forwardly oriented support leg, which is in front of the seat of the automobile 2 fit, and on the ground of the automobile 2 should rest. It is obvious that this front leg the stability of the child seat 1 by providing another point of contact with the automobile 2 improved.

The basic piece 10 is specially designed with Isofix connectors 11 which part of the well-known Isofix system for attaching child seats to automobiles 2 are. Reference information about the Isofix connector 11 can be found on the website of the International Organization for Standardization www.iso.org being found. It is believed that the Isofix connectors 11 The present disclosure is not limited to the current design, but to all future designs of the Isofix connector 11 fall, which suitably at attachment points of the automobile 2 attachable, in a manner which in the present child seat 1 could be integrated.

As the expert person will know, the Isofix connectors provide 11 a rigid and secure connection to the chassis of the automobile 2 ago. The present disclosure is directed to the particular use of the Isofix system for securing the child seat 1 at the automobile 2 directed. Furthermore, the present system allows a rotatable, and possibly tiltable, child seat 1 by allowing the connection through the Isofix system, and still without the on the automobile 2 attached seat belts instructed to be. As discussed above, it is often desirable for the child seat 1 can be turned and tilted to the comfort of the child seat 1 improving the use of the child, which can be achieved with the current design.

At least like that 1 . 6 and 7 can be reconstructed is the current child seat 1 with the base piece 10 and a seat part 3 Mistake. The seat part 3 closes in a rotatable manner to the base piece 10 to the seat part 3 to allow the child, in the front or reverse direction of the car 2 to be aligned. Considering the base piece 10 of the 2 it is clear that this is provided with a number of connector elements. The basic piece 10 closes to the seat part 3 by means of a rotatable element 20 at. The rotatable element 20 can be best in 3A and 3B seen be, again in the forward ( 3A ) and backward ( 3B ) Alignment.

How out 3 is traceable, is the rotatable element 20 attached in a rotatable manner to the base piece. The mechanism for interconnecting these two pieces is as an embodiment in the figures by a variety of supports 13 and holes 21 and grooves 23 shown. This in 3 shown design, and indeed all of the figures, show a system where the rotatable element 20 with the base piece 10 connected in several places. It is obvious that the more connecting points exist between these two elements, the safety of the resulting child seat 1 is larger. However, it is very possible, just a single central rotatable connection point between the base piece 10 and rotatable element 20 provide.

The at the base piece 10 shown central support 13 Can be used to connect to a suitable hole or opening 21 on the rotatable element 20 be used. When the rotatable element 20 over the prop 13 is positioned so that this prop 13 inside the hole 21 is, it is clear that the rotatable element 20 in a rotatable manner on the base piece 10 is held. Furthermore, the support 13 advantageously provided with a cap or a head piece, which with a head 14 larger diameter is provided. The big diameter of the head 14 larger diameter is advantageously larger than the size of the hole 21 in the rotatable element 20 , As can be understood, the rotatable element first reaches over the hole 21 in the prop 13 of the base piece 10 one when the head 14 larger diameter over the support 13 is placed, the base piece 10 and rotatable element 20 but will still allow rotation.

As discussed above, to improve the security of the system, the base piece may 10 be provided with other fasteners. In the figure are second fastening means 15 shown only at the back of the base piece 10 are provided. This will become clear by way of example, and it is also possible to use other second attachment means 15 at the front of the base piece 10 in the area of the front support leg. In a similar way as with the support 13 and the hole 21 , if the rotatable element 20 with an opening in the form of a circumferential groove or track 23 is provided, the second fastening means 15 intervene in it. Again, when the second fastener 15 are provided with a head of larger diameter, that of the second opening, that of the circumferential groove or track 23 , allow to unite with the support portion of the second fastener, with a larger diameter head, which again ensures that they can not come loose. In this case, the rotation of the rotatable element 20 around the central pillar 13 and the hole 21 take place, wherein the second fastening means around or along the circumferential groove or track 23 emotional. As can be seen from the figure, the circumferential groove or track 23 generally towards the edge of the rotatable element 20 intended.

The structure shown in the figures for the rotatable element 20 is that of a disk element 22 , Furthermore, the disc element 22 shown as a portion of an outer surface of a sphere. This is not the only orientation or structure for the disk element 22 and in fact this can be structured as a flat disk. It is understandable that the extent of the circumferential groove or track 23 determines the amount of rotation in which the rotatable element 20 and can move the seat part attached thereto. For the second circumferential groove or track 23 it is preferable to rotate the rotatable member 20 and the seat part 3 of at least 180 °. It is further preferred if the seat part 23 and the rotatable element 20 can rotate 360 °. It is understood that the extension of the groove or track 23 the amount of rotation of the seat part 3 determined because the second fastener 15 this groove or track 23 require to move around the rotatable element 20 or disc element 22 to run around.

As is clear from the above, the rotatable element 20 and the seat part 3 in a rotatable manner on the base piece 10 attached. This means that these two elements have a substantially direct connection to the Isofix connectors of the automobile 2 to have. Through the Isofix connectors 11 at the base piece 10 are the rotatable element 20 and the seat part 3 connected to the chassis of the automobile. That means the child seat is extremely good with the automobile 2 connected, but also in relation to the base piece 10 can be rotated, creating multiple alignments of the child seat part 3 be allowed.

It is possible to use the disc element 22 with a circumferential groove 23 to provide, which runs all the way around to allow a 360 ° turn. In this case, it is clear that the disc element 22 must be formed of two sections. The disc element 22 is therefore preferred by a central disk element 24 which the central passage or the opening 21 includes, and an outer toroidal or annular piece 25 provided. The gap between the inner diameter of the annular piece 25 and the outer diameter of the central disc element 24 creates the circumferential groove or track 23 ,

Is the disc element 22 equipped with these two separate pieces, it is clear that these must somehow be connected. 4 shows the disc attachment means 26 , which can be used to the central disc element 26 and the annular element 25 to attach to each other. It is obvious that it is necessary for the fasteners 26 have such a structure that they are not the upper part of the second fastening means 15 hinder. By providing a suitable gap, it is the second attachment means 15 possible, by the circumferential groove and track 23 to run and the disc fastener 26 to pass, thus a full 360 ° rotation of the rotatable element 20 to allow. Again, the disc fasteners 26 patterned appropriately to the central disc element 24 and the ring-shaped piece 25 hold together to a rigid rotatable element 20 to form, which is suitably and rigidly by means of Isofix connectors 11 with the automobile 2 connected is.

Like both of them 3 and 4 it is also possible to see the seat part 3 in relation to the base piece 10 to allow to tip. By providing aligned grooves or tracks 27 extending from the circumferential groove or track 23 extend, the second attachment means 15 pass into these aligned grooves and the rotatable element 20 allow to move in a forward or reverse direction. That is, in the in 3 and 4 As shown alignment, the second fastening means are aligned 15 with the aligned grooves or tracks 27 , The aligned grooves or tracks 27 are as parallel grooves in the disk element 22 provided so that the disc element 22 with the second attachment means 15 can be weighed back or forward by the aligned grooves or tracks 27 to run. In the figures, the aligned grooves extend 27 from the disk shape of the disk element 22 on a neck or extension. It's obviously just one type of design, and the disc element 22 could be big enough so that its diameter has the aligned grooves or tracks 26 would suitably record. Additionally, the aligned grooves or tracks may be 27 to the center of the disk element 22 extend so that there are several second fasteners 15 through corresponding grooves or tracks 27 can move. This allows the seat part 3 continue to tip forwards and backwards as desired.

As will be further apparent, the hole can 21 within the central disk element 24 also be provided as an extended groove, which the rotatable element 20 It also allows tilting when this is in a certain rotated orientation. Preferably, the aligned grooves or tracks 27 it the seat part 3 allow you to tilt forward or backward when in the fully forward or reverse direction. It is obvious that any other orientation is possible, although generally the most comfortable for the child will be that which is the seat part 3 allowed to tip over when directed either forward or backward.

How best 5 and 6 can be seen, is the rotatable child seat 1 preferably also equipped with a number of seat belts. It is a first seat belt 30 provided, which with the rotatable element 20 connected or connectable. As can be understood from the above, means a direct connection with the rotatable element 20 in that the first seat belt 30 with a direct connection to the chassis of the automobile 2 is provided. That is, the rotatable element 20 at the base piece 10 which is attached with the Isofix connectors 11 equipped to the automobile 2 tie. That means the first seat belt 30 a properly with the chassis of the automobile 2 connected seat belt is. As based on 5 and 6 to recognize, is the first seat belt 30 preferably with the socket 31 or the plug 32 a seat belt connector 33 provided. In the design shown is the socket 31 the seat belt connector at both ends of the first seat belt 30 appropriate. Obviously this serves only as an example and any further combination of these connectors is possible. As apparent from this, connecting a seat belt directly into the seat belt connector means 33 of the first seat belt 30 that this in direct connection with the chassis of the automobile 2 is.

How out 6 and 7 can be seen, is the seat belt connector 33 at the end of the first seat belt 30 preferably oriented so that it from the outside of the child seat 1 is accessible. That is, as shown in the figures, the slot of the seat belt connector socket 31 is on the upper armrest part of the seat part 3 intended. That means the user of the child seat 1 This socket can be used in a suitable manner.

As in 7 shown, the child seat can 1 with a front or lap cushion 40 be equipped. The lap cushion or restraint 40 is used to properly seat the child in the seat part 3 of the child seat 1 to keep. While it is possible to have a harness within the squab 3 of the child seat 1 It is also advisable to provide a lap cushion or restraint which covers the waist and lap portion of the child. This increases the safety of the child seat 1 considerably, as it prevents internal injuries to the child in the event of an accident. As can be understood from the figures, the lap cushion must 40 only with complementary seat belt connectors 41 . 42 Be equipped to connect with the seatbelt connector 33 on the first seat belt 30 unite. If z. B. the first seat belt 30 with seatbelt bushes 31 equipped, the complementary Sitzgurtstecker must 41 on the lap cushion 40 be provided so that the lap cushion 40 suitably directly with the first seat belt 30 can be connected. Thus, the lap cushion 40 by means of the base piece 10 , the Isofix connector 11 towards the rotatable elements 20 and the first seat belt 30 directly to the chassis of the automobile 2 connected. This system means that the child in the automobile 2 is held because the lap pillow 40 in direct connection with the chassis of the automobile 2 stands.

This system is also beneficial because the lap cushion 40 directly with the child seat 1 and does not require the use of an automobile seat belt. It is clear that, with the direct connection to the chassis of the automobile 2 , the lap cushion 40 does not require the seat belt of the automobile 2 over the child seat 1 must be strapped over. In this way the child can with the increased safety of the lap cushion 40 while also providing the increased comfort of a freely rotating child seat 1 which can also be tilted as described above. Since it is not necessary, the child seat 1 Through the automobile seat belt, the orientation and position of the seat part can be adjusted 3 in terms of the chassis of the automobile 2 be adjusted.

As well as from the 5 and 6 be clear, the child seat can 1 also with a second seat belt 50 be provided. This second seat belt 50 is preferred as a seatbelt loop 51 provided. The seat belt 50 Can with the front part of the rotatable element 20 connected or connectable, so that the part of the seat part 3 on the legs of the child with the rotatable element 20 connected is. The seat belt loop 51 runs around the upper side or edge of the seat part 3 and extends around the back of the head part of the seat part 3 of the child. Again, it is clear that the second seat belt 50 in the same manner as above for all other elements in direct connection with the chassis of the automobile 2 is. The seat belt loop 51 is advantageous because if the seat is in a rearward orientation and a frontal impact should occur, the top of the seat portion 3 with the front part of the rotatable element 20 connected and thereby the chassis of the automobile 2 , This prevents longitudinal deformation of the seat part 3 , and prevents, in the first place, that the head part of the seat part 3 deformed too much in such a crash situation. This improves the safety of the child seat 1 further.

How best 5 it is still possible to use both the first and second seat belts 30 . 50 through the disc attachment means 26 on the rotatable element 20 to fix. This is obviously only by way of example, and other attachment means may be provided. Of course, to the number of parts of the child seat 1 to provide a double role for the disc attachment means 26 Not only sure that the first and second seat belts 30 . 50 suitably towards the chassis of the automobile 2 are attached, but the child seat 1 is suitably simplified in its construction. It is also possible, a connection between the first and second seat belt 30 . 50 provide. Again this helps the possible deformation of the seat part 3 To reduce, a collision or accident should occur as the seat belts 30 . 50 tend to warp from the seat part 3 which improves the safety of the child.

As emphasized above, the design of the child seat is 1 such that it is secure to the chassis of the automobile 2 can be fixed and allows both a rotation and a tilting of the seat for the child. In addition, increased security is provided by providing a lap pad or retainer 40 at the child seat 1 without the need for the benefit of the automobile seat belt 6 available. While it is possible that combinations of features in the above form have been specified directly, this is meant to be exemplary only. The above disclosure should in fact be considered as a combination of potential features involving any rotatable child seat 1 and none of the above should be considered as a limiting feature.

Like from the 8a and 8b it is also possible to use a less complex design, which nevertheless has a child seat 1 in direct connection with the automobile 2 via Isofix connectors 11 provides. While the above description describes the possibility of a rotatable child seat 1 to provide shows 8th clearly, that the beneficial aspects regarding the direct connection with the Isofix connectors 11 nevertheless in a child seat 1 can be realized without turning ability.

How out 8a Obviously, the child seat could be 1 as a rear-facing child seat 1 be provided. That is, the Isofix connectors 11 are to the part of the seat 1 arranged closest to the feet of a child in the seat 1 would. In the 8th shown designs show a child seat 1 which is both a basic piece 10 as well as a seat part 3 having. While the figures show these two features individually or singly, it is also possible to use the child seat 1 to structure that the base piece 10 a one-piece part of the seat part 3 forms. That is, the seat part 3 would be structured so that the lower part of the seat part 3 could be used, the seat 1 on the seats of the automobile 2 take off, with the Isofix connectors 11 directly on the seat part 3 are formed.

As from the in 8a shown structure is the seat part 3 with a belt 30 . 50 Mistake. The belt 30 . 50 is preferably a seat belt typical material, but need not be limited thereto. The concept of the belt 30 . 50 It is the seat part 30 Strength for the regrettable event of an impact from the automobile 2 to rent. As described above, the belt 30 . 50 as a seat belt loop 51 be structured, which around the seat part 3 runs around. In fact, the above teachings are with respect to the second seat belt 50 also on the in 8a shown structure applicable. The belt 30 . 50 should loop around and loop 51 form, which is the seat part 3 and the child therein includes to prevent any longitudinal deformation of the seat portion 3 in the event of an accident.

Like from the 8a Obviously, the belt is 30 . 50 in direct connection with the base piece 10 provided, which then a direct connection through the Isofix connectors 11 to the automobile 2 manufactures. That is, there is a direct rigid and stable connection, similar to the above for the rotatable child seat 1 is between the components on the automobile 2 which are connected to the Isofix connectors 11 of the child seat 1 connect, and the belt 30 . 50 , The connection can be created or designed by a rigid design means, which in the seat part 3 is provided, or how out 8a seen in the base piece 10 , The belt 30 . 50 could also be attached to mounting posts or mechanisms attached to the base piece 10 are provided so that the firm connection between the belt 30 . 50 and the base piece 10 is made.

A seat like in 8a could be shown as one of the base piece 10 detachable seat be configured. In fact, that can be done in everyone 1 to 8th described child seats 1 be structured so that they are from the base piece 10 can be removed to a base piece 10 to leave behind, which could be used for different products. As also understandable, the seat part could 3 potentially tipping, resulting in providing the interaction between the seat part 3 and the base piece 10 could be achieved with a rotatable attachment mechanism, so that the strap 30 . 50 always in direct connection with the Isofix connectors 11 is and in the connection no game arises. In such a situation, the belt becomes 30 . 50 any load due to the connection to the Isofix connectors 11 and the connection to the automobile 2 transferred immediately, without any biasing or preloading. This direct and immediate connection is useful as it means that the child seat 1 in terms of the automobile 2 can not move in any way, and through the Isofix connectors 11 is firmly secured.

In the 8a shown designs, as well as all of the previous designs are advantageous because it is for the user of the child seat 1 just not possible, the child seat wrong with the car 2 connect to. The design has no external straps or straps or the like, and thus provides a child seat 1 available, which knows only one type, with the automobile 2 to be connected, namely by the Isofix connector 11 , It is understandable and clear that the user only has a required number of connections through the Isofix connector 11 to the automobile 2 and at this point the child seat 1 directly and correctly with the automobile 2 connected is. There is no requirement for any additional connections between the child seat 1 and the automobile 2 whereby the user is not subject to any difficulties, the child seat 1 appropriately with the automobile 2 connect to.

With a view to 8b is a second orientation of the child seat 1 of the 8a shown. In this orientation is the child seat 1 in a forward-facing position, and the child therefore has his face to the front of the automobile 2 directed. In this orientation, it is understandable that the connection between the child seat 1 and the automobile 2 will be arranged behind the child when in the child seat 1 sitting. In this case, the Isofix connectors are 11 to the back of the seat part 3 located, and again shows 8b the possibility of a basic piece 10 between the seat part 3 and the Isofix connectors 11 provided. In the same way as described above, it will be possible to have one with the seat part 3 one-piece base piece 10 provide so that externally the seat part 3 with Isofix connectors 11 would appear equipped. In the same way as in 8a described is the child seat 1 with a belt 30 . 50 equipped in direct connection with the Isofix connectors 11 is in between, possibly with some solid interconnecting means. When the seat part 3 integral with the base piece 10 is, could the belt 30 . 50 directly with the Isofix connectors 11 be connected, or at least part of the child seat 1 near the Isofix connectors 11 , In the in 8b shown situation is the belt 30 . 50 in direct connection with the interconnecting means between the seat part 3 and the Isofix connectors 11 so that the solid compound described above is again provided.

At the in 8b shown case is the child seat 1 also with a front or lap cushion 40 Mistake. The lap cushion 40 is positioned in front of the child and will cover the lap of the child, thus the child in the child seat 1 hold. The lap cushion 40 is the same as described above, so no further repetition is necessary.

In the case of the rotatable child seat 1 The primary concept is that the strap 30 . 50 , which on the lap cushion 40 possibly through the seat belt connector described above 33 , which provides a full loop around the child, which is attached to the Isofix connectors 11 anchored directly, which means that there is a direct connection that the child in the seat 1 and on the automobile 2 holding.

It will be understandable that the two descriptions of the forward and rearward child seat 1 in a single child seat 1 can be combined, which has two orientations to the front and to the rear. By providing two suitable connection means between the seat part 3 and the Isofix connectors 11 , or via the base piece 10 , could the child seat 1 a multi-positionable child seat 1 be. In any orientation, and indeed for the above-described rotatable child seat, the basic concept of providing the belt is 30 . 50 with a direct loop around the child, either in front of the child or behind the child's head, the same, and therefore means that most of the forces are immediately absorbed and transmitted to the automobile chassis.

Numerous possible modifications of the above designs are also contemplated. For example, in the rotatable child seat 1 the rotatable element 20 described in some respects as a separate element which exists between the seat part 3 and the base piece 10 followed. It is obvious that the rotatable element 20 also as the lower part of the seat part 3 from the child seat 1 could be structured or recorded. That is, the structure and discussion regarding the rotatable element 20 could be considered the lower part of the seat part 3 be included, and therefore as a seat part 3 without the rotatable element 20 appear. Of course, if the seat part 3 can be structured from a sufficiently strong material, a single rotatable element 20 not in the child seat 1 be involved.

As described above, when the child seat 1 in a forward-facing direction is a lap cushion 40 provided to keep the child in place. It is also possible on the lap cushion 40 to dispense and instead provide a simple strap. In this case, the belt could also be a belt having an integral airbag so that in the event of an accident or impact, the airbag inflates and substantially like the lap cushion 40 acts. The use of airbags in seat belts has become known and a variety of possible triggering mechanisms could be devised. It is obviously also possible to put an airbag in the lap cushion 40 to integrate, rather than in a lap belt, the lap cushion 40 replaced. First, it would be possible, the belt or the lap cushion 40 to have it inside of a built-in sensor-typical design, so that when the belt or the lap cushion 40 to some extent under expansion or tension, the system is triggered and the airbag is inflated. A second option would be to connect to the automobile 2 provide, so when the seat 1 via the Isofix connectors 11 which connects to the electrical signal coming from the automobile 2 is provided, and indicates that the automobile 2 had an impact. The signal which usually triggers the airbags on the front driver and passenger seats could also be used, the airbag in the child seat 1 trigger. Finally, it will be possible to have a sensor within the Isofix connection 11 of the child seat 1 to implement. When an impact occurred, it is understandable that the child seat 1 In the direction of travel before the impact or impact is pulled or pushed, and a sudden force would be on the Isofix connection 11 act. When connecting through the child seat 1 is monitored, and a greater force is reported than safety, the airbag could be triggered to inflate.
