Child safety car seat

The innovation relates to a child safety car seat for attachment to the seat upholstery of a motor vehicle with the features of the preamble of claim 1.

Such car seats are preferably attached to the rear seats of motor vehicles. It is already known to use a seat frame to open the seat before the child seat is relatively far over the seat surface of the rear seat of the motor vehicle in order to avoid that in the seat To enable the child taking a seat to look through the vehicle window. This, however, makes the Center of gravity of the seat and child far above the seat of the car seat raised so that a particularly firm one and secure attachment of the child seat and the child sitting therein is required. Conventional child seats of the type in question are therefore with a three-point belt attachment provided, each a strap on the two lower ones, in the joint area of the vehicle seat surface and the vehicle backrest engages lying corner points of a frame lower part and a third belt is arranged in the upper region of the seat frame (frame upper part) or the seat shell is the one with the end remote from the seat on the parcel shelf

If II f ί

of the car is to be attached. Inevitably must to do this, the parcel shelf can be drilled, which at least securely attaches a conventional child seat awkward. In addition, such holes are usually viewed as unsightly and annoying. Often, however, the existing hat shelves are no longer stable enough »to be securely attached of the upper belt or - which can be observed with increasing tendency - on three- or five-door Passenger car in the manner of a "station wagon" no longer exists, which means that it is properly fastened a conventional child seat makes it almost impossible.

As a further prior art, child seats are known that consist of a seat frame without a seat frame the seat resting, usually consisting of foam seat shell and only a tether arrangement need like a two-point attachment.

However, these seats have the disadvantage that the seat of the child seat is very little above the seat of the motor vehicle and thus the child is denied the view from the motor vehicle windows. In addition, in such seats, the seat shell inclination is adjusted by the frameless seat structure not possible.

The innovation is based on the task of a child car seat with a frame and a raised, preferably adjustable incline To train child seat shell in such a way that it is compatible with those already available in motor vehicles Fasteners can be attached in an accident-proof manner. This task is carried out according to the innovation the combination of the characteristics of the indicator of the claim 1 solved.

-δ- The main feature of the innovation is the attachment of a support plate which is attached to the underside of the lower frame part resting on the seat cushion of the motor vehicle and which covers the entire area. As a result, the entire covered upholstered area of the motor vehicle seat is used as a counter-support to absorb the tilting moment that occurs when, during a deceleration process, the mass-affected seat wants to tilt forward in the direction of travel of the car about its pivot point or axis of rotation defined by the Gurtbefesti supply points. This tendency to tilt can be observed the more the lower the seat can sink into the upholstery. Due to the large area of support, the spring counter-torque of the entire impacted cushion surface is used and thus a multiplication of the tilting counter-torque is brought about. In other words, the specific surface pressure of the child seat frame on the car seat upholstery is reduced to such an extent that the deflection tilting movement during the braking process is negligibly small.

The plate also prevents the seat from tipping sideways when cornering, etc. reduced, which contributes to the well-being of the child accommodated in the seat.

A secure fastening of the seat standing up with the plate on the seat upholstery of the motor vehicle is achieved by a two-point attachment on both sides. In particular, the conventional third belt at shoulder height of the seat are omitted, as the hold of the two side straps in cooperation with the support plate already leads to the desired anti-tipping protection.

X ^

A further improvement of the breakdown torque _entgegen-: acting lever arm is achieved in that the support plate is out of claim 2 over the front edge of the seat shell. It should be noted that For example, if the child is properly strapped in the child seat, the center of gravity of the child and the child seat is above the rear third of the support plate, so that the front area of the support plate for interception the tilting forces are available.

A further reduction in the tilting tendency of the seat is achieved by the fact that? according to claim 3 the lateral Two-point tether straps are attached at a distance from the back struts and the frame base in such a way that the The fastening points are approximately at the level of the seat shell bottom surface. This ensures that the two Child seat belts from the seat joint of the vehicle upholstery at an angle of approx. 45 ° upwards ascend to the attachment points, creating a even pulling of the child seat frame into the car seat upholstery is achieved.

A particularly advantageous combination of reducing the tilting moment with a simple attachment option results when the fastening points roughly at the height of the center of mass of the occupied child seat, i.e. roughly in the child's pelvic area lie.

A particularly good distribution of the fastening straps, especially in the event of a frontal impact the seat frame exerted forces is achieved when, according to claims 5, 6 and 7, the fastening straps on in the direction of travel elliptical or non-circular th side struts of the frame are arranged, the

the forward or upward facing surfaces of the back braces, which are approximately at right angles to one another or act on the side tubes of the lower tube part, including the ends of the side struts on matching Are mitred. Due to the relatively long cut surfaces, the force is also not generated punctually, but introduced into the frame tubes over a long, extended area.

Claims 8 and 9 take into account the fact that in particular the front part of the support plate for interception the tilting moments are to be used and the one lying in the area of the seat joint of the motor vehicle seat the rear part only has to be sufficiently rigid to bear the weight of the seat with the child. Through the Openings make the seat lighter overall.

The invention is explained in more detail using an exemplary embodiment shown in the drawing. the Drawing figure shows a perspective view of the renewed seat.

The child safety car seat 1 consists essentially of a tubular frame 2 and an attached, preferably made of plastic seat 3. The tubular frame 2 consists of a parallel to the motor vehicle seat (not shown) running frame base 4 and an integral part of this bent frame oar part 5 together, whose

SC rear struts 6 on both sides in the final assembly state of the seat rest against the back upholstery of the motor vehicle, not shown.

To fasten the seat, two retaining straps 7, 8 are provided, the fastening points of which are 9, 10 on side struts 11,12 are arranged, which the upper Abechnit-

te of the back struts 6 with the front sections of the frame lower part side tubes at an angle.

On the underside 13 of the frame lower part 4, a support plate 14 is provided, which essentially Width of the frame lower part 4 and with its front edge 15 over the front cross strut of the frame lower part 4 and protrudes beyond the front edge 16 of the seat shell 3.

Itr. individual is the arrangement of the attachment points 9, 10 made on the tubular frame 2 as follows: The side struts 11, 12 face in the direction of the seat (arrow 17) an elliptical cross-section and lie with their mitered end faces 18,19 on the surfaces 20, 21 of the side tubes of the frame lower part 4 or of the rear struts 6 facing the seat shell 3 and are welded there. The attachment points 9, 10 left approximately in the middle of the side struts 11, 12, so that the passing through the attachment points 9,10 The axis of rotation 22 extends approximately at the level of the bottom 23 of the seat shell 3.

To reduce the weight of the seat, the support plate 14 is provided with openings in its rear area 24 and provided with reinforcing ribs 25 in their front area pointing in the seat direction 17.
