With the increasing of car ownership, more and more children travel by car, but the seats and safety devices in the car are not suitable for children's body size. In China, a large number of child passengers die in traffic accidents every year, most often in the form of frontal collision, mainly due to the low utilization rate and misuse of child safety seats. The child safety seat itself is overweight and the binding path of the safety belt is not clear and inappropriate, which makes the equipping rate of the child safety seat in the car very low, and the protection effect is very poor. In this paper, the structure optimization and seat belt path optimization of the raised seat are carried out, the purpose is to make the raised seat lightweight, improve the use of convenience and energy efficiency, and study to obtain the best design method of seat belt constraint path, improve the safety of child occupants in the collision.


Here is the content list:

  •  The developing stages of R129 car seat
  •  Major additions to the R129
  •  Restraint system for child members of motor vehicles as required by  R129

The developing stages of R129 car seat

R129, series 00: It is applicable to the ISOFIX child restraint system for general purpose and the ISOFIX child restraint system for special vehicles.
R129, series 01: It is also applicable to the ISOFIX child restraint system for general purpose and the ISOFIX child restraint system for special vehicles.
R129, series02:  It is suitable for the integral universal ISOFIX child restraint system, the special vehicle ISOFIX, the non-integral universal heightening chair with backrest and the non-integral special vehicle heightening chair with backrest.

Major additions to the R129

1. The size of the supporting leg
The supporting legs are located within the range
Adjustable foot adjustable, adjust the spacing not more than 20 cm
The supporting foot area is greater than 25 cm, and the length of the side is greater than 3 cm
2. Internal dimensions of CRS
3. External dimensions
4. Structure: the restraint belt can be adjusted without disassembly within its adjusting range

Restraint system for child members of motor vehicles as required by  R129

(a) complete universal ISOFIX type enhanced child member constraint system,(i-size)
(b) complete special vehicle type ISOFIX type enhanced child member constraint system,
(c) Incomplete general class enhanced child member restraint system (i-size)
(d) Incomplete special vehicle class enhanced child member restraint system
(e) complete general class vehicle seat belt type
(f) complete special vehicle car seat belt type
Complete and not complete, the main difference is how the members of the children complete type refers to the fixed in the car through the child occupant restraint system, the built-in protection device (5 point safety belt three-point seat-belt lead protector), will be fixed non-perfect type children members Refers to by car seat belt, children member is fixed in the car.
General type: it refers to the special vehicle type that can be adapted to most models (90%) on the market. It can also be understood as the specified vehicle type. For example, the size of the child restraint system may be too large to be placed in the A-class car, and it takes up too much space inside the car, so such seats can only be placed in the B-class car or on a bigger car.
