of the mass that it can support:
a) group 0: for children of mass less than 10 kg;
b) group 0+: for children of mass less than 13 kg;
c) group I: for children of mass from 9 kg to 18 kg;
d) group II: for children of mass from 15 kg to 25 kg; and
d) group HI: for children of mass from 22 kg to 36 kg.

3.2 Category

Each child restraint can be classified as belonging to one of the following four categories in terms of the conditions in which It can be used:

a) a universal category: for use as specified in 5.1 .1 and 5.1 .3.1 on most vehicle seat positions;

b) a restricted category: for use as specified in 5.1,1 and 5.1.3.1 in designated seat positions for particular vehicle types as indicated by either the child restraint manufacturer or the vehicle manufacturer;
c) a semi-universal category: for use as specified in 5.1 .1 and 5.1 .3.2; and
d) a specific vehicle category: for use either in specific vehicle types in accordance with 5. 1 .2 and 5.1.3.3, or as a built-in child restraint.

3.3 Class
Each child restraint can be classified as belonging to one of the following two classes:

a) integral class, that comprises a combination of straps or flexible components with a securing buckle, an adjusting device, attachments and, in some cases, a supplementary chair, or an impact shield (or both), that is capable of being anchored by its own integral strap or straps; or
b) non-integral class, that can comprise a partial restraint (see 2.26) that when used in conjunction with an adult seat belt that passes round the body of the child or restrains the device in which the child is placed, forms a complete restraint system.

5 General requirements

5.1 Positioning and securing on the vehicle

5.1 .1 The use of child restraints in the universal, semi-universal and restricted categories (see 3.2)
is permitted in the front and the rear seating position if the restraints are fitted in compliance with the
manufacturer's instructions,

5.1.2 The use of child restraints in the specific vehicle category (see 3.2) is permitted in alt seat positions and in the luggage area if the restraints are fitted in compliance with the manufacturer's instructions. In the case of a rearward-facing restraint, the design shall ensure that the child's head is supported when the restraint is in use.

5.1 .3 Depending on the category to which it belongs, the child restraint shall be secured either to the vehicle structure, or to the seat structure.

5.1.3.1 In the case of the universal category and the restricted category, restraints shall be secured only by means of an adult safety belt (with or without a retractor) that meets the requirements of SABS 1 080 , Restraining devices (safety belts) for occupants of adult build in motor vehicles (revised requirements), or of any equivalent standard, and that has been fitted to anchorages that meet the requirements of the said SABS 1 430.
5.1 .3.2 In the case of the semi-universal category, restraints shall be secured by means of the lower anchorages prescribed in the said SABS 1 430 and additional anchorages that meet the requirements of annex A of this specification.
5.1.3.3 In the case of the specific vehicle category, the restraints shall be secured by means of the anchorages designed by the vehicle manufacturer or by the child restraint manufacturer.
5.1.4 In the case of child restraining straps or child-restraint attachment straps that utilize belt anchorages to which an adult safety belt or belts are already fitted, the test authority shall check that
a) the effective adult anchorage position complies with the said SABS 1430,
b) the effective operation of the one device is not hindered by the other, and
c) the buckles of the adult system and the additional system are not interchangeable.
5.1.5 In the case of child restraint systems thatutilize bars (or extra devices attached to the anchor-ages that comply with the said SABS 1430) that move the effective anchorage position outside the scope of the said SABS 1430, the following shall apply:

5.2 Configuration
5.2.1 The configuration of the child restraint shall be such that
a) the restraint gives the required protection in any intended position of the restraint system; in the case of special-needs restraints the primary means of restraint shall give the required protection in any intended position of the restraint system without the use of the additional restraining devices that might be present
b) the child is easily and quickly installed and removed; in the case of a child restraint system in which the child is restrained by means of a harness belt or a Y-shaped belt without a retractor, each shoulder strap and lap strap shall be capable of movement relative to one another during the procedure prescribed in 6.2.1 .4,
NOTE In these cases, the belt assembly of the child restraint system may be designed with two or more connecting parts. In the case of special-needs restraints It is recognized that the additional restraining devices will restrict the speed by which the child can be installed and removed. However, the additional devices shall be designed to release as quickly as possible.

c) setting the restraint in the inclined position, if possible, can be performed without readjustment of the straps; a deliberate hand-action shall be required in order to put the restraint in the inclined position.
d) a group 0, group 0+ and group I restraint system shall keep the child so positioned that the required protection is provided, even when the child is asleep, and
e) to prevent submarining, either by impact or through restlessness, a crotch strap shall be required on all forward-facing group I restraints that incorporate an integral harness belt assembly; with the crotch strap attached, and in its longest position if adjustable, it shall not be possible to adjust the lap strap to lie above the pelvis of either the 9 kg or the 1 5 kg dummy.
5.2.2 In the case of groups I, II and III, all restraints that use a lap strap shall positively guide the lap strap to ensure that the loads transmitted by the lap strap are transmitted through the pelvis.
5.2.3 All straps of the restraint shall be so placed that they cannot cause discomfort to the child during normal use or assume a dangerous configuration. The distance between the shoulder straps in the vicinity of the neck should be at least the width of the neck of the appropriate test manikin,
5.2.4 The assembly shall not subject weak parts of the child's body (abdomen, crotch, etc.) to excessive stresses. The design shall be such that compression loads are not imposed on the crown of the child's head in the event of a collision.
NOTE Y-shaped belts may only be used in rearward-facing child restraint systems.
5.2.5 The child restraint shall be so designed and installed as to
a) minimize the danger of injury to the child and to other occupants of the vehicle through, for example, sharp edges or protrusions (as defined in SABS 1 047, Motorvehicle safety: Interiorfittings (passenger cars)),
b) not exhibit sharp edges or protrusions that are liable to cause damage to vehicle seat covers or to occupants* clothing,
c) not subject weak parts of the child's body (abdomen, crotch, etc.) to the supplementary Inertial forces that the restraint sets up, and
d) ensure that the rigid parts of the restraint do not. at points where they are in contact with straps, exhibit sharp edges that are capable of abrading the straps.
5.2.6 Any part made separable to enable components to be fixed and detached shall be so designed as to avoid any risk of incorrect assembly and use. as far as possible. Special-needs restraints may have additional restraining devices; these shall be designed so as to avoid any risk of incorrect assembly and so that their means of release and mode of operation are immediately obvious to a rescuer in an emergency.
5.2.7 Where a child restraint intended for group I, group II and for groups I and II combined, includes a chair back, the internal height of the tatter, determined in accordance with the diagram given in annex C of this specification, shall be not less than 500 mm.
5.2.8 Only automatically locking retractors or emergency locking retractors may be used.

5.2.9 In the case of group I restraints, it shall not be possible for the child to easily loosen that part of the system that restrains the pelvis after the child has been installed; any device that is designed to restrain the pelvis shall be permanently attached to the child restraint system.
5.2.10 A child restraint may be designed for use in more than one mass group, provided that it satisfies the requirements laid down for each of the groups concerned.
5.2.11 In thecaseof a child restraint that incorporates a retractor, the retractor shall meet the requirements of 6.2.3.
5.2.1 2 In the case of a booster cushion, the ease with which the straps and tongue of en adult safety belt pass through the fixture points shall be examined. This applies in particular to booster cushions that are designed for the front seats of cars, and that may have long, semi-rigid stalks. The fixed buckle should not be allowed to pass through the fixture points of booster cushions, or to permit a lie of belt completely different fix)m that of the test trolley.
5.2.1 3 If the child restraint is designed to restrain more than one child, each restraint system shall be fully Independent with. regard to load transfer and adjustments.
