Description

The invention relates to a restraint system for small children, for example on the seat of a car seat can be fastened by means of a belt, preferably with a Seat shell and an impact table in which to guide the Belt a belt gap is formed.

Restraint systems are used to transport infants (approx 9 months) and toddlers used in motor vehicles. they are generally in the back seat of a vehicle with Help fasten a strap and prevent the child from falling sudden, heavy braking or on tight bends is hurled through the vehicle. Instead, remains the child in the restraint system and is only on or against the impact table and the formwork walls of the seat shell pressed, which are however padded and / or made of foamed Plastic. In this way, for example Traffic accident, the risk of injury to the child is very low held.

A known restraint system has a seat shell and one Impact table with belt gap on, the table on the Seat shell is attachable. For the exact placement of the opening baffle on the seat shell are at the bottom of the Table protrusions formed while on the formwork wall Appropriate grooves of the seat shell are provided. However, the known restraint system has several Disadvantages. If the child has outgrown the seat shell, it can So, for reasons of space, they can no longer be placed in these a restraint would still be necessary is one Can no longer use this system. The same Problem occurs when the seat shell is damaged or is dirty and can no longer be used. Close Lich the known impact table has a manufacturing technology disadvantage. This table is made of foamed art  material. The plastic is made into an ent injection-molded shape. After foaming and cooling the form must be removed. The removal is due to the Training the belt gap, however, very problematic, so that the table is undercut in the area of the gap that must be in order to be able to extract it from the form at all. In spite of of this additional work it happens relatively often that an impact table is damaged or breaks when removed.

The object of the invention is to provide a restraint system to make it easy and inexpensive to manufacture as well as easy to clean and which may also be without Seat shell and larger toddlers can be used can, with a secure attachment of the impact table or the system itself should be guaranteed on the car seat.

This object is essentially ge according to the invention triggers that side cheeks in the form of Feet are designed such that the cheeks when opening sit on the seat - omitting the seat shell - form a push-through opening for the legs of the toddler. In this way, the restraint system according to the invention is for Small children of two age groups or weight classes is suitable. It has been shown that for children with the weight Class from 9 to 18 kg or the age group of nine months up to the age of three (so-called group I) the seat shell in Connection with the impact table must be used. For Group II children weighing 15 to 25 kg or the age group from the age of three is over Only the impact table should be used for reasons of space. The Formation of the side cheeks in the form of feet ge in this case ensures an adequate lateral fixie the child's cheeks, especially when cornering absorb any lateral forces that occur. In contrast for this purpose, only short ones are known at the known impact table Projections formed, but only as a guide for serve the table and do not offer lateral support. At Using the well-known table without a seat shell could do that  Child pressed against the belt with strong lateral forces and injure yourself.

The restraint system according to the invention can be used universally in all Vehicle types are used, provided that they comply with the ECE Regulation No. 16 or other comparable standards geneh approved pelvic / 3-point / static / retractor seat belts are equipped.

In a further development of this inventive idea, that the distance between the cheeks is greater than the width of the Seat of the seat shell. This ensures that the impact table due to its larger clear width also for the outgrown child (group II) white ter can be used.

The impact table is placed on the seat shell easily facilitated by the fact that in the seat shell a tour especially in the form of sloping to the outside Steps for the cheeks of the impact table is formed, which also prevents the table from moving sideways becomes. The cheeks thus take over two radio simultaneously tion, namely guiding the table on the seat shell and Absorption of lateral forces when using the system without Seat shell.

The greatest possible width while avoiding annoying channels ten is achieved when the adjacent outer sides of the tub gene and the seat shell with the impact table in the white considerable curses. This way, too a particularly simple guide for the impact table on the Seat shell guaranteed. Eventually the system gets one Appealing aesthetic appearance, as seat shell and on appear plump as a unit.

Measurements and tests have shown that the largest The height of the push-through opening must be at least 6 cm since with the cheeks provide sufficient support and a ver  risk of injury by cutting into the belt is avoided. The optimal height was determined at about 11 cm, with take into account that there is too much vertical clearance is intolerable since the child will not be out in this case is fixed.

Another idea of the invention provides that the impact table is formed at least in two parts. By that measure can take the manufacturing problems that known impact tables occur, who effectively avoided the. The respective parts of the impact ti according to the invention This can easily be removed from the mold, damage conditions and breaks do not occur.

It has been shown that there are already enormous manufacturing tech niche benefits if the impact table only is formed in two parts. The impact table points here a mounting element with cheeks and a swivel element. At Finally, the two-piece design offers a table sufficient stability under loads.

Another embodiment of the invention provides that The pivoting element is articulated on the mounting element is that when pivoting the pivot element of the belt gap can be enlarged. Here, the belt gap is both by the This allows the belt to be easily and without twisting insert the belt gap as this can be expanded.

In a particularly simple embodiment of the articulated Connection have the attachment element and the pivoting element Openings or a hole on and are a through connected axis.

If a belt attachment area is formed on the swivel element, the inserted belt swivels when the swivel is swiveled always with the element and cannot twist.  

The belt contact area expediently includes itself preferably formed as a slant overhang, the ver prevents the belt from swinging down the pivoting element is clamped between this and the attachment element and may not be able to tighten.

To essentially shift the belt vertically prevent, is in the attachment element at least one guide for the belt, preferably belt guide incisions on each Outside of the impact table, trained.

Advantageously, the guide is upwards through a Projection limited, so that accidental folding up movement of the vehicle is avoided.

To ensure good belt guidance, this is Restraint system with at least one belt guide element Belt slit on the outside of the impact table, on one arm of the element one towards the Slit-facing nose is arranged. With the help of the strap guide element, the belt can be easily tightened where the belt slipping out of the element largely prevented. The belt guide element can be used as a individual casting is made of plastic and is thus very easy and inexpensive to manufacture and the same timely safe.

To easily tighten the belt when tightening increase, it is provided that the belt guide element Has belt guide recess, the nose over the Belt guide recess protrudes. At the same time, through this measure the risk of the belt slipping out the belt gap further reduced.

To further improve the guidance of the belt is on one belt guide element each on the outside of the impact table ment arranged.  

A good hold and high stability when fastening the belt guide elements on the impact table are reached, if they are connected to the axis. Another advantage this feature is that the belt guide elements also pivot when pivoting the pivoting element up and down, so that the belt is always flat against the impact table. Finally, the belt guide elements can be used by the user themselves are moved, thereby inserting the strap is lightened.

The goal of the stability of the entire belt guide with belt guide Rungselemente and axis is particularly useful when the axis made of metal, preferably steel.

Another advantageous feature of the invention provides that the system at least one by means of a closure device opening and exchangeable cover for the seat shell and / or the impact table with attachment element and Has pivot element, the shape of the seat shell and / or of the impact table essentially corresponds. Hereby can the cover of the seat shell and / or the impact table Dirt removed and cleaned in a simple manner will. Especially with the two-part impact table bie ten the benefits the significant advantage that this is due the "simple" form of attachment and swivel element easily can be pulled up and down. In contrast to that the covers in the known systems are sewn and can not be changed. It also prepares for raising and sewing the covers onto the known impact tables already in the production due to the training and poor accessibility of the belt gap great difficulty ten.

To be able to pull the cover on and off easily, is the Closure device of the seat shell on its back and Un arranged at the bottom. The U-för serves the same goal arrangement of the closure device of the attachment element in the area of the push-through opening and that the closure  Direction of the swivel element U-shaped on the edge of the upper is partially arranged.

In a particularly simple embodiment it is provided that the Closure device is a zipper. However also other closure systems such as Velcro, button closures conclusion or the like possible.

The references advantageously exist at least partially Made of cotton and are therefore easy to care for and / or wear washable material, such as synthetic leather, so that smaller Ver dirt can be easily wiped off without the cover need to wash immediately.

Further goals, features, advantages and possible applications the invention result from the following description an embodiment with reference to the drawing. Make it up all described and / or illustrated features for yourself or in any meaningful combination the opposite stood of the invention, regardless of their synopsis solution in the claims or their relationship.

The restraint system 1 shown in FIGS. 1 to 3 has a seat shell 2 and an impact table 3 . The shell 2 'is provided with a seat surface 2' and a back abutment surface 2 ', each of which protrude from their lateral edges formwork sections 11 to 14, which serve for the lateral fixation and stabilization of a small child in the seat shell 2, in particular while cornering. A belt guide element 4 , 5 for receiving and guiding a lap belt is provided on the outer sides of the impact table 3 . Furthermore, a belt gap 6 is formed in the impact table 3 , into which the lap belt can be inserted to fix the impact table 3 on the seat shell 2 and to hold and fasten the entire restraint system 1 on a car seat.

As can be seen in particular from FIGS. 4 to 6, a guide in the form of a step 7 , 8 is provided in the formwork sections 13 , 14 of the seat surface 2 '. The steps 7 , 8 are arranged on the outer sides of the formwork sections 13 , 14 and extend substantially over the length of the seat surface 2 'and the formwork sections 7 , 8th The Stu fen 7 , 8 go directly into the outer walls of the Schalungsab sections 13 , 14 .

The seat shell 2 is completely covered with a cover 9 , preferably made of cotton, the cover 9 essentially corresponding to the shape of the seat shell 2 and fitting tightly against it. The cover 9 can be completely removed from the seat shell 2 dig. For this purpose, it is provided with a zipper 10 on the back and underside of the seat shell 2 ( FIG. 7). Instead of the zipper 10 , a Velcro or button closure or the like can also be provided.

The impact table 3 shown in FIG. 8 is formed in two parts and has a mounting element 15 and a pivoting element 16 , the pivoting element 16 being articulated on the mounting element 15 . In this game Ausführungsbei the element 15 is provided with two lateral, hochste existing bearing sections 17 , 18 , in each of which there is an opening 19 , 20 . The belt guide elements 4 , 5 can be inserted into the openings 19, 20 and connected to one another via an axis 21 , which will be discussed in more detail later (cf. in particular the explanations for FIG. 17).

The attachment element 15 from FIG. 8 is covered with a completely removable cover 22 which can be opened via a zipper 23 . The zipper 23 is U-shaped on the underside of the attachment element 15 in the region of a push-through opening 24 .

In Figs. 10 to 12, the fitting member 15 is shown in more detail without reference. When viewed from the front, it has an H-shape, the two bearing sections 17 , 18 extending upwards, while downward-facing cheeks 25 , 26 are provided. Between the cheeks 25 , 26 and the bearing sections 15 , 16 there is a central web 27 which on its underside has two recesses 28 , 29 for the legs of the toddler. The push-through opening 24 , which is open at the bottom, is located between the cheeks 25 , 26 as a lateral boundary and the central web 27 as an upper boundary. On the upper side of the telstegs 27 , a recess 30 is provided which extends essentially over its entire width and is provided with a bevel 31 . In the area of the bearing sections 17 , 18 each belt guide incisions 32 , 33 are formed, each of which is delimited at the top by a projection 34 , 35 .

In FIGS. 13 to 16 shown pivoting member 16 is in Fig. 13 gene with a completely removable cover 36 Plated which is openable over a at the edge of the upper part of the pivoting element 16, located U-shaped arrangement of zipper circuit 37th The shape of the covers 22 , 36 essentially corresponds to that of the corresponding elements 15 , 16 , so that the covers 22 , 36 lie closely on the elements 15 , 16 . The covers 22 , 36 can at least partially consist of a washable material such as synthetic leather, and otherwise of cotton.

The pivot element 16 has a through bore 38 for receiving the axis 21 . On its underside, the swivel element 16 , like the attachment element 15 , is provided with two recesses 39 , 40 which, when assembled, are aligned with those of the attachment element 15 . To form the belt gap 6 , a projection 41 is formed on the swivel element 16 , which at the same time forms part of the surface of the impact table 3 . Below the protrusion 41 is the belt attachment area 42 , from which an incline 43 extends.

In Figs. 17 to 19 is the belt-guiding element 4, shown in more detail. 5 The element 4 , 5 has an upper guide section 44 and an insertion shaft 45 running essentially perpendicular thereto. The insertion shaft 45 opens into a screw bore 47 , which is accessible from the upper guide section 44 . In the opening of the insertion shaft 45 , the axis 21 is insertable. The axis 21 is hollow and provided with an internal thread 46 . When inserted in the shank 45 shaft 21 , this can be screwed via a screw 48 inserted through the screw hole 47 . In this example, the screw 48 is a hexagon screw.

The guide section 44 has a belt guide recess 49 which is delimited by lateral, projecting edges 50 , 51 and speaks essentially the width of the lap belt. To insert the lap belt into the belt guide element 4 , 5 , this is provided with an approximately S-shaped belt slot 52 . The slot 52 is delimited towards the outside by an arm 53 which overlaps the lap belt. At its free end, the arm 53 has a nose 54 pointing in the direction of the slot 52 , which has a more pronounced S-shape, the nose 54 being at least slightly raised and protruding from the belt recess 49 . The nose 54 is covered by this when the lap belt is inserted, thereby contributing to its tension. At the bottom of the free end of the arm 53 , an insertion slope 55 is provided to facilitate the insertion of the lap belt into the slot 52 . In particular for manufacturing reasons, the insertion shaft 45 is arranged eccentrically on the guide section 44 . The eccentricity simultaneously causes the opening of the belt slot 52 due to the inherent weight of the guide section constantly points down and facilitates the insertion of the belt.

For assembly of the impact table 3, the fitting member 15 and the pivot member are first coated with 16 jeweili gen covers 22 and 36th Then the axis 21 is inserted into the insertion shaft 45 of a belt guide element 4 and screwed via the screw 48 . The Schraubboh tion 47 is designed such that the screw head does not protrude beyond the belt guide recess 49 . After insertion of the pivot member 16 between the bearing portions 17, 18 of the axis 15 is guided Aufsetzelementes of Schwenkel ementes 16 21 through the opening 19 of the bearing portion 17 and the bore 38th Then the belt guide element 5 is inserted through the opening 20 in the bearing section 18 onto the free end of the axis 21 and screwed as described. Here, the insertion shafts 45 of the belt guide elements 4 , 5 protrude into the bore of the swivel element 15 .

To use the restraint system 1 , the seat pan 2 is placed on the front or rear seat of the vehicle. After the child has been placed in the seat shell 2 , the impact table 3 is placed on the seat shell 2 . The undersides of the cheeks 25 , 26 lie on the steps 7 , 8 . The inner side surfaces of the cheeks 25 , 26 lie on the outer of the steps 7 , 8 approximately without play, so that a lateral displacement of the impact table 3 on the seat shell 2 is prevented. The outer surfaces of the cheeks 25 , 26 merge flush with the outer adjacent surfaces of the formwork sections 13 , 14 .

To insert the lap belt, the swivel element 16 is swung up something, whereby the belt gap 6 is expanded and the insertion is made easier. At the same time, the belt contact area 42 also pivots. When swiveling down, the bevel 43 adjoining the belt contact area 42 lies in the recess 30 with a corresponding bevel 31 .

Finally, the lap belt is inserted into the belt guide elements 4 , 5 via the respective belt slots 52 , so that it is tightened and tightened accordingly, which is necessary for structural reasons. If the vehicle is equipped with a 3-point belt system, the shoulder belt must be guided past the back of the seat shell 2 during or after the lap belt is inserted.

If the child has outgrown the seat shell 2 (group II), then only the impact table 3 can be used as a child restraint device. Here, the shoulder strap must be led past the child. In this case, the cheeks 25 , 26 with the impact table 3 preferably extend as far as the seat of the vehicle seat and thereby offer corresponding lateral support. Taking into account the circumference of a thigh of a small child, the greatest height of the push-through opening 24 measured from the highest point of a recess 28 , 29 should be at least 6 cm, so that the cheeks 25 , 26 offer sufficient lateral support. In the illustrated embodiment, the height is about 11 cm, the cheeks 25 , 26 in Ge use, that is, with legs pushed through, stand up on the seat of the vehicle.
