Description

Technical field

The invention relates to the field of removable child restraints, child car seats, for attachment to motor vehicle seats, equipped with three-point safety belts according to ECE.

BACKGROUND OF THE INVENTION

Until now, various designs of child restraint systems have been used for attachment to motor vehicle seats, in particular to rear seats of passenger cars equipped with ECK safety belts of a three-point retractor system. The most commonly used are various types of shell, solid, shaped car seats, equipped with a suitable lining and upholstery, which are attached especially to the rear seats of the car and are intended for specified groups according to ECE. These solid, shell, shaped car seats are structurally demanding and difficult to handle even when used in cars. Another disadvantage is that they occupy space even when they are not occupied by the child, both in the car seats and in the luggage compartment when the child seat is removed from the car seat.

Apart from these main types of car seats, there is also known a technical solution of a child seat according to CZ utility model No. 16313, which consists in that it consists of an inflatable shaped body made of rubber material provided with textile surface treatment, which is further provided with at least one air valve and provided at the selected locations with shaped side projections especially for guiding the head of the child, the actual shaping of this solution not being specified.

The disadvantage of this type of inflatable infant car seat is in particular the rubber material used, which does not provide sufficient user comfort and the fact that the detachable attachment of the infant car seat to the vehicle seat consists of either five-point adjustable integrated seatbelts attached to the fastening plate located behind the seatback. protecting the chest and abdomen of a sitting child with another inflatable insert.

In the field of inflatable products, multi-chamber mattresses and seats are known which allow seating, the shape of which is determined by a system of internal partitions, partitions, in the case of inflatable mattresses ph simple assembly, where the headrest serves as a seat, or seat directly designed. However, these products cannot be recommended for their design and the material used for the child seat.

SUMMARY OF THE INVENTION

Most of the drawbacks of the child restraints used so far for use in motor vehicles are solved by an inflatable child restraint consisting of an inflatable unicameral body consisting of an outer shell and inner partitions, dividing walls disposed between the upper and lower walls of the outer shell and provided with a charge and discharge valve. characterized in that the lower inner bulkhead of the inflatable unicameral body is arranged obliquely towards the rear of the back of the inflatable unicameral body and that the lower inner part of the inflatable single-chamber body back is vertically or diagonally its upper part at least one inner cushion of the cushion is attached towards the rear of the back of the inflatable single-chamber body

An inflatable unicameral body when its lower part is attached to the bottom wall of the outer casing of the inflatable unicameral body, and further internal partitions disposed in the space between the upper wall and the bottom wall of the outer casing to define the shape of the backrest and seat of the inflatable unicameral body the bodies are located at a specified distance from the circumferential lines of the inflatable unicameral body parallel to the circumferential lines of the inflatable unicameral body, and are situated perpendicularly and / or parallel to the longitudinal axis of the inflatable unicameral body to define the shape and height set intervals. The backrest of the inflatable unicameral body is in its upper part equipped with an expanded upper rim for locating the elements necessary to fix the fastening strap of the vehicle, the guiding of the child's body being formed by circumferential elements and supporting parts of the seat and back of the inflatable unicameral body. and the lower strap holder is a two-piece strap with a buckle, and preferably serves as an auxiliary fixation of the seat position relative to the seatback of the inflatable child restraint, and the recommended lashing routes for the motor vehicle are marked graphically on the front of the backrest and seat cushion. The inflatable single-chamber body is made of synthetic fabric with a plastic coating on one side by means of RF welding, and for inflating and deflating it is equipped with an inflating and blowing valve and for the operating pressure is further provided with a pressure relief valve.

The arrangement of the inner partitions, partitions, inflatable child restraint for use in motor vehicles according to the invention allows the backrest and seat to automatically assume the anatomically shaped shape of the inflatable child restraint, i.e. the backrest in the raised operating position and the seat in the horizontal position. and also forming circumferential elements and seat and backrest portions, which thereby form a lateral guidance of the body of the child to be transported in the inflatable child restraint for use in motor vehicles.
