  2.  Definitions
 For the purposes of this Regulation,
2.1. "Approval of a vehicle" means the approval of a vehicle type with regard to the strength of the seats and their anchorages, the design of the rear parts of the seat‑backs and the characteristics of their head restraints;
2.2. "Vehicle type" means a category of motor vehicles which do not differ in such essential respects as:
2.2.1. The structure, shape, dimensions, materials and the mass of the seats, although the seats may differ in covering and colour; differences not exceeding 5 per cent in the mass of the approved seat type shall not be considered significant;
2.2.2. The type and dimensions of the adjustment, displacement and locking systems of the seat‑back and seats and their parts;
2.2.3 The type and dimensions of the seat anchorages;
2.2.4. The dimensions, frame, materials and padding of head restraints, although they may differ in colour and covering;
2.2.5. The type and dimensions of the attachments of the head restraint and the characteristics of the part of the vehicle to which the head restraint is attached, in the case of a separate head restraint;
2.3. "Seat" means a structure which may or may not be integral with the vehicle structure complete with trim, intended to seat one person. Depending on its orientation, a seat is defined as follows:
2.3.1. "Forward-facing seat" means a seat which can be used whilst 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;
2.3.2 "Rearward-facing seat" means a seat which can be used whilst 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;
2.3.3. "Side-facing seat" means a seat which can be used whilst 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;
2.4. "Bench seat" means a structure complete with trim, intended to seat more than
