This standard applies also to car seats complying with ECE 44 tha

29、t can be used as reclined cradles according to manufacturers instructions. This standard does not apply to reclined cradles when used as swings. If a reclined cradle has several functions or can be converted into another function the relevant European standards apply to it (see Annex B). 2 Normative

34、 bouncing and may have an adjustable backrest and/or seat. 3.1.1 static reclined cradle article not intended to bounce or rock 3.1.2 rocking reclined cradle article intended to allow the child to rock DIN EN 12790:2009-07 EN 12790:2009 (E) 6 3.1.3 bouncing reclined cradle article intended to allow t

35、he child to bounce due to the flexibility of the frame or any other mechanical means 3.2 restraint system system to restrain the child within the reclined cradle 3.3 crotch restraint device designed to pass between the childs legs to prevent the child from sliding forward 3.4 carrying handle compone

Key LL Junction line Figure 1a) Junction line NOTE 2 When the seat unit is in the form of a hammock, then a theoretical junction line, “LL”,

37、is determined as shown in Figure 1b). For these products the junction line will vary when the backrest is adjusted in different positions.

38、 a hammock 4 Properties of materials 4.1 Chemical properties Surfaces of parts located within the inner and upper surface that support the child shall be made using materials which in their soluble state have a metal content not exceeding the following values: Antimony: 60 mg/kg; Arsenic: 25 mg/kg;

39、Barium: 1 000 mg/kg; Cadmium: 75 mg/kg; Chromium: 60 mg/kg; Lead: 90 mg/kg; Mercury: 60 mg/kg; Selenium: 500 mg/kg. The test procedure is defined in EN 71-3. Where a surface is coated with a multi-layer of paint or similar coating, the test sample shall not include any of the base material. 4.2 Flam

40、mability There shall be no parts of the reclined cradle which can give rise to surface flash, when tested in accordance with EN 1103. DIN EN 12790:2009-07 EN 12790:2009 (E) 8 5 Construction 5.1 Shrinkage After cleaning and drying twice in accordance with the manufacturers instructions, any resulting

41、 shrinkage in the fabric covering materials shall not prevent removable fabrics from being refitted. 5.2 Finger entrapment When tested in accordance with 6.3 there shall be no holes, openings or gaps greater than 7 mm and less than 12 mm unless the depth of penetration of the appropriate probe is le

42、ss than 10 mm on the inner and upper surface which supports the child. The test shall be carried out with the product in any intended position of use. Restraint systems are excluded from this requirement. 5.3 Moving parts To avoid the risk of shearing and crushing once the reclined cradle is assembl

43、ed for normal use the distance between two parts which move relative to each other shall be less than 5 mm or more than 12 mm throughout the entire movement. Moving parts can arise from: a) the movement of the reclined cradle; b) the movement of the body weight or action of the child using the recli

44、ned cradle; c) a powered mechanism. Locking mechanisms and the base of the article and its functional parts for rocking and bouncing are excluded from this requirement. 5.4 Edges, points and corners All accessible edges, corners and protruding parts on the reclined cradles inner and upper surface wh

45、ich supports the child shall be rounded or chamfered and free from burrs. All surfaces shall be free from burrs and sharp edges. 5.5 Small parts When tested in accordance with 6.4, any part that can be detached shall not fit wholly within the small parts cylinder. Parts intended to be removed shall

46、not fit wholly within the small parts cylinder. 5.6 Cords, ribbons and parts used as ties Cords, ribbons and parts used as ties excluding restraint system shall have a maximum free length of 220 mm when stretched by a force of 25 N. 5.7 Springs If the reclined cradle is fitted with springs, a protec

47、tion is required when the space between two helical coils can become equal to or greater than 3 mm and smaller than 12 mm, when tested in accordance with 6.5.

48、torage or transportation purposes shall be fitted with locking mechanism(s) for the folding system. Locking mechanism(s) is required to prevent a reclined cradle folding whilst the child is in the cradle and also during the process of a child being put in and taken out of the cradle. 5.8.2 Incomplete deployment To avoid the hazard due to incomplete deployment, at least one locking mechanism shall engage automatically when the product is deployed for use in accordance with the manufacturers instructions f
