Therefore, in most countries, the use of child safety seats is obligatory for the purpose of preventing the death of children due to transportation accidents, and the standard system (ISOFIX system) for safety seats installed in vehicles has been introduced in line with this purpose. .

For reference, the standard system of safety seats (ISOFIX system) is based on the frame structure of each seat, and in particular, a fixing point in the form of a loop fastener is formed between the cushion and backrest of each seat, but the loop fastener is Consists of ISOFIX steel bar,

A latch or clip extending from the lower part of the child safety seat is engaged and fixed with the loop fastener, so that the safety seat is stably fixed in each seat.

However, in the standard system (ISOFIX system) as described above, since the safety seat itself is made to fit the body type of children, when an adult boards, the seat can only be boarded after removing the safety seat, and conversely, when a child boards, The inconvenience of having to re-install the safety seat on the seat and the limitation of the space used were disadvantages.

Therefore, a seat (Registration Patent No. 10-1348542) that can be used as a safety seat for children while being made of a flexible material as a whole has been developed, which can be used as an adult car seat.

Seats such as the above are not only inconvenient to install and store, but also when the vehicle suddenly stops suddenly or an external force occurs due to a collision,

As shown in Fig. 2, the child's center of gravity is suddenly shifted to the front according to the law of action and reaction, and at this time, the shoulder belt 101 holds the upper body, and the seat back 120 and the safety seat 100 located at the rear end ), the rear space (S) between them is widened.

At this time, if the weight of the child is too much, it shows a movement to move away from the seat, and there is a risk of causing serious injury by collide with the front seat if done wrong.

This is to support the upper body so that it does not lean forward.

In this case, the support legs 60 may be fixedly installed by descending from the lower fixed frame 32 in the case of a school vehicle in which each seat of the vehicle is manufactured to fit the size of children, but in the downward direction according to the size of the seat of a general passenger car. It is preferable to further include a support (61) that is length-adjustably extended in the front so that it can come down.

At this time, the support leg 60 and the support 61 include a length adjusting means 50 and an angle adjusting means 60, and the angle adjusting means 60 is disposed between the upper fixed frame and the lower fixed frame. It may be installed, but may be simply configured to be foldable by a hinge means.

In addition, the length adjusting means 50 is configured to be adjustable in length while being accommodated in multiple stages in the support rod 62 or the lower fixed frame, since the support legs and the supports have different cross-sectional areas (eg, diameters). At this time, a plurality of protrusions 51 that are elastically supported on the inside are caught in the locking groove 52 and the length of the support leg is adjusted so that when an impact is received, it is possible to prevent the opening of the rear space or the child's leaning in front. . In this case, the length adjustment means may be configured to be length-adjusted in various ways, including a screw coupling method, according to embodiments, but is not limited thereto.
