2.18. Seat
A structure which may or may not be integral with the vehicle structure complete with trim, intended to seat one adult person. The term covers both an individual seat or part of a bench seat intended to seat one person.
2.18.1. “A front passenger seat” means any seat where the “foremost H-point” of the seat in question is in or in front of the vertical transverse plane through the driver’s R-point.
2.18.2. “Forward-facing seat” means a seat which can be used while the vehicle is in motion and which faces towards the front of the vehicle in such a manner that the vertical plane of symmetry of the seat forms an angle of less than + 10° or -10° with the vertical plane of symmetry of the vehicle.
2.18.3. “Rearward-facing seat” means a seat which can be used while the vehicle is in motion and which faces towards the rear of the vehicle in such a manner that the vertical plane of symmetry of the seat forms an angle of less than +10° or -10° with the vertical plane of symmetry of the vehicle.
2.18.4. “Side-facing seat” means a seat which can be used while the vehicle is in motion and which faces towards the side of the vehicle in such a manner that the vertical plane of symmetry of the seat forms an angle of 90° (±10°) with the vertical plane of symmetry of the vehicle.
2.19. Group of seats
Either a bench-type seat or seats which are separate but side by side (i.e. fixed so that front seat anchorages of one of these seats are in line with the front of the rear anchorages of the other or between the anchorages of the other seat) and accommodate one or more seated adult persons.
2.20. Bench seat
A structure complete with trim, intended to seat more than one adult person.
2.21. Adjustment system of the seat
The complete device by which the seat or its parts can be adjusted to a position suited to the morphology of the seated occupant; this device may, in particular, permit of:
2.21.1. Longitudinal displacement;
2.21.2. Vertical displacement;
2.21.3. Angular displacement.
2.22. Seat anchorage
The system by which the seat assembly is secured to the vehicle structure, including the affected parts of the vehicle structure.
2.23. Seat type A category of seats which do not differ in such essential respects as:
2.23.1. The shape, dimensions and materials of the seat structure;
2.23.2. The types and dimensions of the seat lock adjustment and locking systems;
2.23.3. The type and dimensions of the belt anchorage on the seat, of the seat anchorage and of the affected parts of the vehicle structure.
2.24. Displacement system of the seat
A device enabling the seat or one of its parts to be displaced angularly or longitudinally, without a fixed intermediate position (to facilitate access by passengers).
2.25. Locking system of the seat
A device ensuring that the seat and its parts are maintained in any position of use. 2.26. Enclosed buckle-release button
A buckle-release button such that it shall not be possible to release the buckle using a sphere having a diameter of 40 mm.
2.27. Non-enclosed buckle-release button
A buckle-release button such that it shall be possible to release the buckle using a sphere having a diameter of 40 mm.
2.28. Tension-reducing device
A device which is incorporated in the retractor and reduces the tension of the strap automatically when the safety-belt is fastened. When it is released, such a device switches off automatically.
2.29. “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.
2.30. “ISOFIX child restraint system” means a child restraint system, fulfilling the requirements of UN Regulation No. 44 or UN Regulation No. 129, which has to be attached to an ISOFIX anchorages system, fulfilling the requirements of UN Regulation No. 14 or UN Regulation No. 145.
2.31. “ISOFIX position” means a system which allows installing:
(a) Either a universal ISOFIX forward facing child restraint system as defined in UN Regulation No. 44;
(b) Or a semi-universal ISOFIX forward facing child restraint system as defined in UN Regulation No. 44;
(c) Or a semi-universal ISOFIX rearward facing child restraint system as defined in UN Regulation No.44;
(d) Or a semi-universal ISOFIX lateral facing position child restraint system as defined in UN Regulation No. 44;
(e) Or a specific vehicle ISOFIX child restraint system as defined in UN Regulation No. 44;
(f) Or an i-Size child restraint system as defined in UN Regulation No. 129;
(g) Or a specific vehicle ISOFIX child restraint system as defined in UN Regulation No. 129.
2.32. “ISOFIX Anchorages System” means a system made up of two ISOFIX low anchorages, fulfilling the requirements of UN Regulation No. 14 or UN Regulation No. 145, and which is designed for attaching an ISOFIX child restraint system in conjunction with an anti-rotation device.
2.33. “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.
2.34. “Anti-rotation device”
(a) An anti-rotation device for an ISOFIX universal child restraint system consists of the ISOFIX toptether;
(b) An anti-rotation device for an ISOFIX semi-universal child restraint system consists of a top tether, the vehicle dashboard or a support leg intended to limit the rotation of the restraint during a frontal impact;
(c) An anti-rotation device for an i-Size child restraint system consists of either a top tether or a support leg, which is intended to limit the rotation of the restraint during a frontal impact;
(d) For ISOFIX, i-Size, universal and semi-universal, child restraint systems the vehicle seat itself does not constitute an anti-rotation device.
2.35. “ISOFIX Top Tether Anchorage” means a feature, fulfilling the requirements of UN Regulation No. 14 or UN Regulation No. 145, such as a bar, located in a defined zone, designed to accept an ISOFIX top tether strap connector and transfer its restraint force to the vehicle structure.
2.36. A “guidance device” is intended to help the person installing the ISOFIX child restraint system by physically guiding the ISOFIX attachments on the ISOFIX child restraint into correct alignment with the ISOFIX low anchorages to facilitate engagement.
2.37. “ISOFIX marking fixture” means something that informs someone wishing to install an ISOFIX child restraint system of the ISOFIX positions in the vehicle and the position of each corresponding ISOFIX anchorages system.
