3.6

child restraint system

CRS

free-standing device intended to provide child vehicle occupants with an approved restraint

Note 1 to entry: CRSs comprise various categories such as car beds, infant restraints, toddler seats (forward and rearward-facing), booster cushions, and booster seats. Combination products may cover two or more of these product categories.

3.7

connector

connecting and locking device to the universal interface, provided with the child restraint system, and part of the attachment

3.8

hidden slack

unintended looseness of a strap that is likely to adversely affect the performance of the CRS, and that cannot be easily detected or can only be detected by handling the CRS attachments in a non-standard way

3.9

ISOFIX

system for the connection of CRS to vehicles, which has two rigid anchorages in a vehicle seating position located near the seat bight, corresponding rigid attachments on the CRS, and a means to limit the pitch rotation of the CRS

Note 1 to entry: In this part of ISO 29061, the term ISOFIX is extended to include flexible CRS attachments (LATCH, UAS).

Note 2 to entry: Adapted from ISO 13216-1:1999.

3.9.1

ISOFIX accessibility tester

device used to check the accessibility of an ISOFIX anchorage

Note 1 to entry: The dimensions are defined in Figure 3, ISO 13216-1:1999.

3.9.2

ISOFIX anchorages

two horizontal rigid bars, 6 mm in diameter and at least 25 mm long, as specified in ISO 13216-1, installed in vehicles in or near the seat bight, and to which two ISOFIX attachments are connected to secure the lower part of the CRS

Note 1 to entry: Anchorages may be rigid or semi-rigid according to Annex A of ISO 13216-1:1999.

3.9.3

ISOFIX attachments

two hardware assemblies, built into the CRS base at 280 mm apart, that meet the requirements of ISO 13216-1 and are used to connect a CRS to ISOFIX anchorages

Note 1 to entry: Attachments may be rigid or non-rigid according to Annex B of ISO 13216-1:1999.

3.10

misuse

any deviation from the intended application and use of a CRS that might reduce its protective performance

3.11

non-rigid attachment flexible attachment

one of two (2) prescribed connections, in accordance with ISO 13216-1:1999, Annex B, flexibly supported from the child restraint system structure, between a CRS and an anchorage

Note 1 to entry: A non-rigid (flexible) attachment may consist of a CRS connector or hook supported by webbing or the equivalent. A CRS connector is an attachment with certain specified dimensions designed to be rigidly supported, described in ISO 13216-1:1999, Figure 8. When designed according to ISO 13216-1:1999, Annex B, a CRS connector may be flexibly supported.

Note 2 to entry: Adapted from ISO 13216-1:1999.

3.12

pictogram

illustration or photo used to represent a concept or an operation

Note 1 to entry: It may be supplemented by text.

3.13

rebound bar

type of anti-rotational device intended to restrict the rearward rotation of a rearward-facing CRS

Note 1 to entry: It usually comprises a rigid device that, when in its operational position, rests against the car seatback.

3.14

rebound tether

lower tether

type of anti-rotational device intended to restrict the rearward rotation of a rearward-facing CRS

Note 1 to entry: It usually comprises a tether strap or other hardware attached near the back or base of the CRS that connects to a rebound tether (lower tether) anchorage. It incorporates a device to enable it to be connected to such an anchorage.

3.15

rebound tether anchorage

lower tether anchorage

anchorage on the vehicle seat track or on or close to the vehicle floor to which a rebound tether (lower tether) can be attached

3.16

seat bight

area close to the intersection of the surfaces of the vehicle seat cushion and the seatback or squab

3.17
