Abstract

A child seat is described which has at least one seat element (12), a backrest element (14) and side walls (18), wherein at least one side wall (18) arranged at the level of the backrest element (14) has a receptacle in which a damping element (12) is mounted. 20) is arranged, wherein the damping element (20) is at least partially pivotable out of the receptacle.

Description

A child seat is described that has at least one seat element, a backrest element and side walls. In addition, the child seat on a side impact protection that protects a recorded in the child seat child in a side impact from injury. Child seats do not include so-called baby carriers and child seats for children, which are taken upright in a child seat.

Side impact protection devices for child seats are known from the prior art essentially for headrests. For example, describes DE 10 2006 033 784 A1 a child safety seat with a top of a backrest mounted or relative to this relatively vertically displaceable arranged headrest part, which consists of a central part and thereto laterally mounted, projecting side walls to protect the child's head against side impact. At least the window side of the vehicle arranged side wall of the headrest on the central part is pivotable about a pivot joint and from a substantially perpendicular to the central part extending protective position in at least one outwardly folded further use position can be brought. For protection in a side crash, it is provided that the side wall from the further use position to the starting position is automatically traceable by external force effects on the side wall in the protective position.

The Indian DE 10 2006 033 784 A1 described child seat allows for a side impact and a deformation of vehicle side parts an automatic pivoting back of the issued part of the side wall.

Disadvantages here are that, on the one hand, only the child's head is protected and, on the other hand, a failure of the protective device can occur if, for example, the deformation of vehicle side parts does not take place in the region of the flared side wall of the child seat. In addition, a joint is prone to failure. In a side impact, the force on the exposed part can act at different angles. It is possible that not for all angles, under which vehicle parts act in an intrusion on the flared part, a pivoting takes place.

It is therefore an object to provide a child seat with side impact protection, which overcomes the disadvantages of the prior art, is simple and meets the requirements of Standard ECE-R129 ("ISize").

The object is achieved by a child seat with the technical features specified in claim 1. Advantageous developments are specified in the dependent claims in detail.

A child seat, which solves the above object, has at least one seat element, a backrest element and side walls, wherein at least one arranged at the level of the backrest element side wall has a receptacle in which a damping element is arranged, wherein the damping element at least partially out of the receptacle is pivotable.

In a first position, the side wall of the child seat has a certain thickness. By swinging out at least a portion of the damping element, the thickness of the side wall is increased. The increased thickness of the sidewall makes it possible to absorb more energy that occurs in a side impact. After swinging out at least a portion of the damping element of the pivoted part is positioned to the side wall, that one side of the pivoted part bears against a further part of the damping element or the side wall of the child seat. In the pivoted position of the part can regardless of the direction of the example. Vehicle parts act on the child seat, a damping take place. This is to be understood in particular with regard to lateral effects, which however can also occur at different angles. In an unactuated position of the damping element, the child seat has a size which has the dimensions specified according to "iSize" standard. The additional side impact protection for the child seat is also provided by simple means. It is not necessary to provide special triggering and locking mechanisms.

In further embodiments, the damping element may comprise at least one first damping body and a second damping body, which are pivotable relative to each other, wherein the first damping body or the second damping body are pivotable out of the receptacle.

One of the two damping body remains even with a pivoting of the other damping body in the receptacle in the side wall. If the two damping bodies consist of a material that absorbs energy in particular, an absorption layer is provided by folding over the second damping body or the first damping body and the abutment of the two damping bodies together, for example, twice as thick as alone by one of the two damping body.

The first damping body or the second damping body may be fixedly connected to the side wall of the child seat or via fastening means with the receptacle in the side wall.

In further embodiments, the first damping body and the second damping body may be connected via fastening means in the receptacle in the side wall.

The damping element with a first damping body and a second damping body can be completely removed from the receptacle out. It is thus possible to replace the damping element, if this has been deformed for example due to a side impact and thus irreparably damaged.

The first damping body and the second damping body may comprise holding means, via which the first damping body and the second damping body are connected to each other in the pivoted state of the first damping body or the second damping body. The first damping body and the second damping body are held in a position via the retaining means, wherein the two damping bodies form a damping element with an increased thickness. The holding means are chosen and connected to the damping bodies that they do not automatically go during use of the child seat when driving in a non-pivoted state.

The damping element may in particular consist of an energy-absorbing material or have an energy-absorbing material. Energy-absorbing materials are known from the prior art and are already used for child seats, especially in the area of a seat cushion and back rest. These materials can be used for a damping element, wherein, for example, the folding of two damping body, the damping element is increased overall.

The first damping body and the second damping body may be connected to each other via at least one hinge. For example, the first damping body and the second damping body are connected to each other via a film hinge. The film hinge is part of a cover which at least partially covers or holds the damping body. However, the cover is formed and covers only a certain, small area of the damping body so that the cover does not limit the energy absorption in the event of a side impact. In particular, the cover is designed so that a deformation of the damping body, which consist of an energy absorbing material, can be performed. The cover may for example consist of a resilient material. At least the cover must be so flexible and / or so connected to the damping bodies, that the damping effect is not limited.

The damping element may consist of foam and / or have a flexible shell. A flexible shell can be formed for example by a fabric cover. Also, a hinge can be formed over a fabric cover. A hinge is to be understood as a means which allows pivoting of a first damping body to a second damping body. For example. both damping bodies can be accommodated in a cloth bag, wherein between the two damping bodies runs a seam which forms a hinge.

The fastening means and / or the holding means may be magnets or magnets. For example, the first damping body and the second damping body can be held in the pivoted position to each other via magnets. It is also possible to hold the first damping body or the second damping body via magnets in the receptacle, said damping body so held by magnets can form the non-pivotable part. Instead of magnets also Velcro closures can be provided.

In further embodiments, a locking element is arranged in the receptacle, which holds the first damping body or the second damping body in the receptacle. The locking element holds the pivotable damping body to increase the damping element in the non-pivoted position. To increase the damping element, the locking element can be moved, whereby the corresponding damping body can be pivoted. The damping body can then be connected, for example via magnets with the fixed damping body. As a locking element, for example, a magnet, a slider or a Velcro connection can be provided.

In still other embodiments, the child seat has a triggering mechanism that is coupled to the first damping body or to the second damping body and that performs or initiates pivoting of the first damping body or the second damping body. For child seats various trigger mechanisms are known, for example, tighten a belt or perform other protective functions after a crash has been detected. Such a mechanism may also be used to perform the pivoting of the first damping body or the second damping body, so that the damping element for energy absorption in a side impact is increased.

In the previously described variants of a child seat only one of the side walls, which is connected, for example, with the backrest element, a damping element or both side walls may have a damping element. In a damping element with two damping bodies, for example, the first or the second damping body can be pivoted on the side which faces a vehicle side part. In this case, for example, the first or the second damping body of a damping element is pivoted, which faces a side window. The damping element on the opposite side of the child seat is not moved because in a side impact vehicle side parts would not press against the seat. However, it is also possible to pivot both damping elements in a child seat. A child seat may have both one or two damping elements on the side walls in the region of the backrest element and a damping element on at least one of the side walls in the region of the seat element. This provides extra protection for a child's legs and pelvis during a side impact. In particular, a protection of the upper body of the child is provided via the damping element in the region of the backrest. In addition, a protection of the head can be provided. The protected body part of a child can be achieved by the targeted provision of at least one damping element. In child seats and several damping elements may be provided which extend over the entire side surface of the child seat and are arbitrarily pivotable to provide appropriate protection functions.

Further advantages, features and design options will become apparent from the following description of the figures of non-limiting embodiments to be understood.

The seat element 12 has side walls 16 and the backrest element 14 side walls 18 on. The side walls 16 and 18 can be molded or integrally formed with the corresponding backrest and seat sections. In addition, the child seat 10 not further specified in the figures and the description of specified components. For example, includes a child seat 10 a belt system, seat and back cushions and fabric covers.

Furthermore have child seats 10 Attachment for a motor vehicle. For example, the child seat shown in the figures 10 be connected in the form of a baby carrier via a so-called ISOFIX connection with a vehicle seat. For this purpose, the child seat 10 either directly connected to a vehicle seat via appropriate ISOFIX connectors or via a carrier connected to a vehicle seat via ISOFIX connectors.

At least one of the side walls 18 has a recording 40 on. The recording 40 serves to accommodate a in 1 not shown damping element 20 ,

2 shows a schematic side view of a child seat 10 , The child seat 10 is designed as a so-called reboard child seat. Such a child seat 10 can be additionally pivoted so that he is in a rest position (see 6 ) can be spent. It is possible, the child seat 10 both for children in the first months of life (0 to 6 months) and for older children to use. It is also possible that Sitting position to spend a pivoting in a rest position as well as in a sitting position.

The child seat 10 from 2 has a recording 40 in the area of the side wall 18 on. The size of the picture 40 and thus the size of the damping element 20 are shown by way of example in the figures. The child seat 10 can in both sidewalls 18 and 16 a recording 40 in which a damping element 20 is included. In addition, the shots 40 and the damping elements 20 essentially over the entire area of side walls 16 and 18 extend. As a result, the protective function is increased because a greater energy absorption is possible.

3 shows an enlarged rear perspective view of a child seat 10 , In 3 is the damping element 20 shown, which consists of a first damping body 22 and a second damper body 24 consists. The damping body 22 and the damping body 24 consist of foam or other energy absorbing material. A deformation of the damping body 22 and 24 absorbs the energy released in a side impact. The absorbed energy can thus no longer on a child seat 10 absorbed energy and protects the child from injury. In particular, vehicle parts are retained in an intrusion and their kinetic energy through the damping element 20 absorbed.

The first damping body 22 and the second damping body 24 are completely within the recording 40 added. The first damping body 22 and the second damping body 24 may also have a cover surrounding the foam. About the reference, the first damping body 22 and the second damping body 24 also be connected to each other. The first damping body 22 is firmly in the recording 40 arranged and can for example via fasteners, such as magnets or Velcro systems safely in the recording 40 be held. The second damping body 24 Can via a locking element 34 (See example meadow 5 ) in the recording 40 being held. After releasing the locking element 34 is the second damping body 24 to the first damping body 22 from the exception 40 swing out. By pivoting the second damping body 24 becomes a damping element 20 provided, for example, whose thickness is twice as large as by one of the damping body 22 and 24 , Presses a vehicle part on the side wall in the event of a collision 18 , so must with a pivoted damping body 24 a greater force on the sidewall 18 act until a deformation of the sidewall 18 occurs and thus a danger for the child exists. This means that a larger amount of energy can be absorbed until it comes to a child injury, since the damping element 20 has a greater thickness in the direction of the introduction of force. Compared to a conventional child seat, the child seat described herein 10 in the area of the side wall 18 be enlarged. An enlargement of the side wall thickness is in particular the damping element 20 increased. In conventional child seats are often foam pad on the inside, ie provided on the body of the child side facing. These foam pads can also achieve a certain damping. However, the known child seats on the outside of a hard plastic shell that allow little or no attenuation. Act on the plastic shell forces by impacting vehicle side panels, can break the shell and cause additional injury to the child. In the child seat described herein 10 is the second damping body 24 from the side wall 18 also off, so that only a contact with the damping element 20 occurs until the sidewall 18 comes in contact with impinging vehicle parts.

In the case of the right side wall 18 from in the 4 illustrated damping element 20 is a partially pivoted state of the second damping body 24 shown. The first damping body 22 has a magnet 26 and the second damping body 24 a magnet 28 on. When pivoting in the direction of the arrow shown, the two magnets 26 and 28 come into contact with each other and hold the second damping body 24 in the pivoted position. For this purpose, the magnets have 26 and 28 a corresponding polarization. Instead of magnets 26 and 28 Velcro fastening systems can also be used. The strength of the magnets 26 and 28 depends on the size of the damping body 22 and 24 and the permissible release force for separating the magnets 26 and 28 , In addition, it must be ensured that the connection or installation of the two damping body 22 and 24 is not resolved in a side impact or other similar event.

5 shows an enlarged perspective view of a damping element 20 , 5 shows in particular a locking element 24 for holding the second damping body 24 is provided in a non-pivoted position. The locking element 34 can be moved to the left, where it is in a corresponding receiving opening on the second damping body 24 engages and a cover 30 holds. The cover 30 consists of a relatively flexible plastic and covers only a small part of the second damping body 24 , The flexible design and shaping ensure that the energy absorption of the damping body 24 and the underlying damping body 22 is not affected. Rigid covers 30 could break and thus provide an additional risk of injury. A possible embodiment of securing the second damping body 24 in a non-use position, for example, in 7 shown.

The cover 30 has hinges 32 on, which are formed for example as a film hinge. The cover 30 is about the hinges 32 connected to a further cover, which is connected to the first damping body 22 communicates.

6 shows a further schematic side view of a child seat 10 , In 6 is the in 2 shown child seat 10 shown in a pivoted position. The child seat, also shown as a reboard child seat 10 can be spent in a corresponding rest position. In such a position even small children (0 to 6 months) can be safely transported.

This is the upper shell of the child seat 10 which the seat element 12 and the back element 14 includes, shifted with respect to the unnamed lower carrier. Thus it does not lead to an unintentional shifting of the child seat 10 or its components comes, further locking means are provided.

As in 6 illustrated, the second damping body 24 be pivoted about the axis A and then lies on the first damping body 22 on. The damping body 22 and 24 have here corresponding surface sections. The thickness of the individual damping body 22 and 24 can be different. In further embodiments, the two damping bodies 22 and 24 essentially the same dimensions. This occurs when pivoting the second damping body 24 to a coupling of the thickness of the damping element 20 , In the non-actuated state are the two damping body 22 and 24 essentially in one plane and aligned with the outside of the sidewall 18 , This will make a child seat 10 provided that meets the specification in terms of the "iSize" standard.

7 shows a schematic representation of a damping element 20 with a first damping body 22 and a second damper body 24 in a recording 40 on the side wall 18 , 7 shows a schematic section through the side wall 18 in the region of the damping element 20 , The recording 40 can, as in 7 shown, have different recording depths.
