Suggested height and age are reference only
Mass of targeted infant is 10 kg or less or 13kg or less, stature is 70 cm or less and age is up to 1 year old.
For infant, there are bed type and rearward facing type.
Targeted child is mass of 9 to 18kg, stature is 65 to 100 cm and age is 1 to 4 years old. However, there is one CRS covering for infant and toddler (so call usage for both infant and toddler).
Stature of targeted child is 150 cm or less, age is around 4 to 12 years old.
This CRS is designed to allow the use of adult seatbelt through lifting child hip up and adjusting it to adult hip position.
However, CRS assesment does not include this category.
The reason is that performance of this type CRS is greatly influenced by vehicle seatbelt performances.
Child seats need to be changed as your child grows.
As for the dual-purpose type, the methods of installation and use depends on the time of use, so be careful not to
change the seat at the wrong timing.
Without the use of a CRS, the child will be thrown out.
If you don't use your CRS correctly, your child could be thrown out of the seat! A CRS should installed correctly.
Products that conform to the safety standards of the Ministry of Land, Infrastructure, Transport and Tourism are marked with the following type designation mark or type approval mark on the product.
In October 2006, the standards related to CRS were reviewed and harmonized with UN-Regulation No.44 (4th Revision) based on the United Nations Agreement on Agreement conserning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (1958 Agreement) from the viewpoint of international harmonization of vehicle standards.
Also beginning in September 2013, UN-Regulation No.129 regarding the improved CRS under the 1958 Agreement was introduced.
Under the new safety standards, UN-Regulation No.129 (i-Size), only the ISO-FIX fixation method is available for the CRS.
In addition to the conventional front and rear impact standards, side impact standards have been added, and installation standards, which were previously classified according to weight, are now classified according to height, making it possible to better match the CRS to the child's body size. Also, safety has been improved in various aspects, such as the clarification of the conditions for switching to the forward-facing position as 15 months or older and 76 cm or taller.
Some of the CRSs cannot fit some type of the vehicles.
Please reffers and confirms CRS manufacturers' recommendation chart which are explain fitness to the vehicles, and then select proper CRS to fit for your vehicle.
In recent years, CRSs conforming to the new safety standard, UN Regulation No.129 (i Size), have become commercially available. i Size CRS can be installed in seats that are listed as i Size in the vehicle's instruction manual, as well as in seats of vehi cles for which the CRS manufacturer has confirmed conformity with the standard . For details, please contact the CRS manufacturer.
The installation method of the CRS varies from product to product, so please follow the respective instruction manuals.
There are two ways to fix a CRS to a seat: by using a car seatbelt or by using a common attachment device (ISO-FIX).
When using a car seatbelt to fasten the product to the seat, there are two types: a two point type and a three point type, depending on how t he seatbelt is fastened.
In the method of fixing to the seat using the common attachment (ISO-FIX), the child seat is fixed to the seat with special metal fittings attached to the back of the seat, and the support leg supporting the lower part or the top tether supporting the upper part eliminates wobble and hold the seat firmly in place . Anyone can install it easily and securely.
Many conventional CRSs are fastened to the seat using a car seat belt, but the method of fastening a CRS to the seat using a se at belt is often misused, and in such a state, the CRS may not provide its original safety performance.
Therefore, in October 2006, a review of CRS standards was conducted, and a type of CRS that is fixed to the car seat by a common installation device (ISO-FIX) is now on the market. In addition, all passenger cars (with a seating capacity of less than 10 passengers) newly released on the market after July 2012 are equipped with common fittings compatible with ISO-FIX CRS. (Some of passenger cars made befor e July 2012 are also equipped with common fittings.)
Since ISO-FIX CRS are easy to install, it is said that there is less misuse during installation compared to the type that is fixed to the seat using a car seat belt.
Use a safer ISO-FIX CRS that anyone can install easily and securely.
3 points fixing method using 3 points seatbelt
Don't child play with seatbelt. The mechanism may change to ALR and if the belt is tangled with child neck or body, it will be happened serious injury such as a suffocation, due to belt cannot loosen. In the case of an emergency, and not to unfasten the belt, you should cut the belt by the scissors.
This is a seat with a common ISO-FIX CRS compatible fixture attached to the back of the seat. Anyone can install easily and securely a CRS by fixing it to the seat with the common fixture withou t using a seat belt. (Some of passenger cars before July 2012 are also equipped with common fittings.)
Since an ISO-FIX CRS is easy to install, it is said that there is less misuse during installation compared to the type that uses automobile seat belts to secure it to the seat.
Normally, CRS is built in the vehicle seat (normally rear seat), and may use as the CRS after pulling out from the vehicle seat when child is on boad. Now a day, some imported vehicle has the CRS for school children (so call junior seat) as a optional equipment.
