At present a vast number of various child’s car seats are designed, differing from each other in configuration, type of fastening, adjustments, additional appliances, etc. All these seats could be conventionally included into the “stationary” category, for they constantly occupy either a place in the compartment or considerable space in the car trunk. This could be regarded as their drawback.

A need in the seat during a day is time-limited, the rest of the time it may hinder transportation of people and cargo. In addition, all these seats do not provide for the child’s protection at the back hit of the car.

The purpose of the invention is to design a seat, by its dimensions occupying the minimum space in the car trunk when it is not needed. It should be lightweight and convenient to be moved from the compartment to the trunk and back. This should be realized by way of replacing the shock-absorbing materials constituting the seat with air, thus making it both cheaper and safer.

To achieve the set purpose, the seat should be folded by the crease between elements, similarly to a carton. The invention is described below on its performance examples with the help of the drawing. Fig. 1a – position of a child in the seat in the usual position; Fig. 1.b – position of a child in the seat in the moment of the back hit of the car; Fig. 2 – the seat general view; Fig. 3 – the seat rigid framework in the expanded form; Fig. 4 – the seat in the folded form.

The key elements of the seat 1 are as follows: the rigid framework 2 (Fig. 3) and airtight cover (not showed). The seat 1 itself (Fig. 2) comprises the headrest 3 with side lobes 4, to support the head, the seat with armrests 5 and back 6 with side lobes 7, for the child’s chest. The base of the seat is the framework 2 placed inside the airtight cover accurately fitting with the configuration of the seat 1. While the seat cover is filled up with air, either from the integral compressor connected to the car power network through the lighter, or from the driver’s lungs, it (the cover) falling out shapes into the child’s seat. At that, the air pocket of the cover is divided into two parts. The first part is the headrest 3 with side lobes 4, and the second part is the seat with armrests 5 and back 6 with side lobes 7. The second pocket is connected with the first one via the direct air valve (not showed). This valve opens at the moment the back of the child, as a result of the back hit of the car, puts pressure upon the second pocket causing the air from the second pocket to move to the first one. The purpose of this is to prevent the child’s head and upper body “stalk” fluctuation. At that the headrest 3, moving towards the head, (the active headrest) and side lobes 4 (Fig. 1b) increase in volume, thus eliminating the head’s rapid motion forward and decreasing the load on the child’s neck. All the elements of the rigid framework have arresters by the crease, enabling them to unfold to about 90 degrees. When the seat 1 is no longer needed, the air is removed, it is folded by the grease (Fig. 4) and placed in the car trunk until the need occurs.  

The seat of the given construction will ensure passive safety and enable to protect the child from injuries in case of a car crash. Any trip in this seat would seem shorter and pleasant, especially, if the child’s seat will be placed on the front passenger seat inclined backward beforehand (http://www.sciteclibrary.ru/eng/catalog/pages/5723.html).
