United Nations ECE Regulations and Safety Standards :
Safety Standards : ECE R44.03 and ECE R44.04 Child restraints (baby seats, child seats, booster seats and booster cushions) sold in the UK must conform to the United Nations ECE Regulation R44.03 or later standard (R44.04). (Child restraints that conform to a British Standard
or to an earlier version of R44, may continue to be used, although as
these will now be several years old, parents should consider replacing
them with a seat that conforms to R44.03 or R44.04).
United Nations ECE Regulation No. 44
To conform to the Regulation, a child restraint must meet a series of design and construction requirements and pass a series of performance tests.
Main Design Requirements Seat Belt Routing If a restraint is to be used with an adult seat belt, the correct routing of the seat belt webbing must be clearly indicated by a drawing permanently attached to the restraint. If the restraint is held in place by the seat belt, the route(s) of the webbing must clearly marked and color coded red for forward-facing seats and blue for rearward facing ones. Restraints in Groups I, 2 and 3, must positively guide the "lap strap" to ensure that the loads transmitted by the "lap strap" are transmitted through the pelvis. To prevent slipping under the harness, either by impact or through restlessness, a crotch strap is required on all forward-facing Group I restraints which incorporate an integral harness. The Buckle It must not be possible for the buckle to be left in a partially closed position and it must only lock when all parts are engaged. The operation of the buckle must be immediately obvious to a rescuer in an emergency. The buckle release area must be red, but no other part of the buckle should be this color. For Group 2 and 3 child restraints, the child occupant must be able to reach the buckle. Child's Position
Performance Tests Impact Tests Frontal Impact Rear Impact During the tests, the test dummy must not be thrown forward more than a set distance and it must not receive an impact force above a specified level. No part of the child restraint that helps to keep the child in position shall break, and no buckles or locking system shall release. The seat belt must not become disengaged from any guide or locking device. Overturning Buckle Markings the manufacturer's name, initials or trade mark the year of production the international approval mark - a circle surrounding the letter "E", an approval number and the symbols: E/ECE/324 the weight range for which the child restraint has been designed an address to which the customer can write to obtain further information on fitting the child restraint in specific cars. Rear facing child restraints must have a permanently attached label, visible in the installed position, with the warning: "EXTREME HAZARD - Do not use in passenger seats equipped with airbags". Child restraints that can be used forward and rear facing, must have a warning including the words: "IMPORTANT - DO NOT USE FORWARD FACING BEFORE THE CHILD'S WEIGHT EXCEEDS xx (Refer to instructions)"
Instructions
The weight groups for which the device is intended. The method of installation illustrated by photographs and/or very clear drawings. A recommendation that rigid items and plastic parts must be installed so that they are not liable, during everyday use of the vehicle, to become trapped by a movable seat or in a vehicle door. A recommendation to use carry-cots perpendicular to the longitudinal axis of the vehicle. For rearward facing systems, a warning not to use them in seating positions where there is an airbag installed (this advice must also be clearly visible at the point of sale without removing the packaging). If the restraint is designed to be used with an adult seat belt, advice about which type of seat belt is suitable. For seats that can be used both forward and rear-facing, a clear warning to keep the restraint rear-facing until the child's weight is greater than a stated limit, or some other dimensional criterion is exceeded. A clear explanation of the operation of the buckle and adjusting devices. A recommendation that any straps holding the restraint to the vehicle should be tight, that any straps restraining the child should be adjusted to the child's body, and that straps should not be twisted. The importance of ensuring that lap straps are worn low down over the pelvis. A recommendation that the restraint should be changed if it has been in an accident. Instructions for cleaning. A warning not to make any alterations or additions to the restraint and to follow the manufacturer's instructions when installing and using it. A recommendation that children are not left in their child restraint unattended |
