21, annex 1. The apparatus shall be positioned as described in that annex to Regulation No. 21 and set to the maximum length of 840 mm.

2.16.                           "Thorax load limiter function" means any part of the safety-belt and/or the seat and/or the vehicle intended to limit the level of the restraint forces applying to the occupant thorax in case of a collision.

2.17.                           "ISOFIX" is a system for the connection of child restraint systems to vehicles which has two vehicle rigid anchorages, two corresponding rigid attachments on the child restraint system and a mean to limit the pitch rotation of the child restraint system.

2.18.                           "ISOFIX position" means a system which allows to install:

              a)                  either an universal ISOFIX forward facing child restraint system as defined in Regulation No. 44,

              b)                 or a semi-universal ISOFIX forward facing child restraint system as defined in Regulation No. 44,

              c)                  or a semi-universal ISOFIX rearward facing child restraint system as defined in Regulation No. 44,

              d)                 or a semi-universal ISOFIX lateral facing position child restraint system as defined in Regulation No. 44,

2.19.                           or a specific vehicle ISOFIX child restraint system as defined in Regulation No. 44."ISOFIX low anchorage" means one 6 mm diameter rigid round horizontal bar, extending from vehicle or seat structure to accept and restrain an ISOFIX child restraint system with ISOFIX attachments.

2.20.                           "ISOFIX anchorages system" means a system made up of two ISOFIX low anchorages which is designed for attaching an ISOFIX child restraint system in conjunction with an anti-rotation device.

2.21.                           "ISOFIX attachment" means one of the two connections, fulfilling the requirements of Regulation No. 44, extending from the ISOFIX child restraint system structure, and compatible with an ISOFIX low anchorage.

2.22.                           "ISOFIX child restraint system" means a child restraint system, fulfilling the requirements of Regulation No. 44, which has to be attached to an ISOFIX anchorages system.

2.23.                           "Static force application device (SFAD)" means a test fixture that engages the vehicle ISOFIX anchorages systems and that is used to verify their strength and the ability of the vehicle or seat structure to limit the rotation in a static test. The test fixture is described in the figures 1 and 2 annex 9.

2.24.                           "Anti-rotation device"

              a)                  An anti-rotation device for an ISOFIX universal child restraint system consists of the ISOFIX top-tether.

              b)                 An anti-rotation device for an ISOFIX semi-universal child restraint system consists of either a top tether, the vehicle dashboard or a support leg intended to limit the rotation of the restraint during a frontal impact.

              c)                  For ISOFIX, universal and semi-universal, child restraint systems the vehicle seat itself does not constitute an anti-rotation device.

2.25.                           "ISOFIX top tether anchorage" means a feature, such as
