5.4. The head restraint and its anchorage shall be such that the maximum backward displacement X of the head permitted by the head restraint and measured in conformity with the static procedure laid down in paragraph 6.4.3. below, is less than 102 mm. If any movement of the feet has occurred during the rocking operation of the 3-D H machine, they must be repositioned as follows: Alternately, lift each foot off the floor the minimum necessary amount until no additional foot movement is obtained. /    The rear parts of seat-backs of vehicles of category M1 are considered to comply with the provisions of paragraphs 5.1.3. and 5.1.4. of this Regulation provided they comply with the provisions of Regulation No. 6.5.3. 5.4.5. (see paragraphs 4.4.; 4.4.1. and 4.4.2. of this Regulation), Vehicle with seats not fitted or not capable. 3.2. 4.1. The function of this vehicle standard is to specify requirements for seats, their attachment assemblies, their installation and any head restraint fitted, to minimise the possibility of occupant injury due to forces acting on the seat as a result of vehicle impact. For Omnibuses complying with ADR 68/... only the driver’s seat is required to comply with clause 5. of this standard. She likes to apply her … LEP & LEG category vehicles must comply with M1 and N1 category vehicle requirements respectively. This will give you 25cm of space between your legs and the height of the bench which is usually a good amount of room. The projection of the reference line of the manikin shown in annex 3 to this Regulation is then, in the seat concerned, drawn in the plane specified in paragraph above. If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by the structure, move the left foot until it is supported. For vehicle categories, definitions and meanings used in this standard, refer to: 4.2. 1.1.2. 5.8. For the test, the head restraint, if adjustable shall be placed in the most unfavourable position (generally the highest) permitted by its adjustment system. 2.2.1. For integrated head restraint, the limit between the head restraint and the seat-back is the one defined in paragraph 5.15.1. The direction of load application shall be maintained along a line passing by the above intersection to a point just above the thigh bar housing (see figure 2 of appendix 1 to this annex). All prices are in AUD 4.4. The 3-D H machine should not be left loaded on the seat assembly longer than the time required to perform the test. Trade name or mark of the motor vehicle  ................................ 2. The above approval mark when affixed to a vehicle shows that the vehicle type has seats not fitted or capable of being fitted with head restraints, and was approved in the Netherlands (E4) pursuant to Regulations Nos. Longitudinal position of the seats during the tests  ..................... 10. "Design torso angle" means the angle measured between a vertical line through the "R" point and the torso line in a position which corresponds to the design position of the seat‑back established by the vehicle manufacturer; 2.8. 3.1. For rear seats or auxiliary seats, the legs are located as specified by the manufacturer. */     The reference system corresponds to ISO standard 4130 : 1978. This requirement is deemed to be met if in the tests carried out by the procedure specified in annex 6 the deceleration of the headform does not exceed 80 g continuously for more than 3 ms. Description of seat anchorage  ........................................... 9. The strength of the seat‑back and of its locking devices is deemed to meet the requirements set out in paragraph 6.2. below when, after testing in accordance with paragraph below, no breakage of the seat or seat‑back has occurred; otherwise, it shall be shown that the seat is capable of meeting the test requirements set out in paragraph 6.2. below. If the 3-D H machine tends to slide rearward, use the following procedure. If the vehicle conforms to a vehicle type approved under one or more other Regulations annexed to the Agreement in the country which has granted approval under this Regulation, the symbol prescribed in paragraph 4.4.1. need not be repeated; in such a case the Regulation and approval numbers and the additional symbols of all the Regulations under which approval has been granted in the country which has granted approval under this Regulation shall be placed in vertical columns to the right of the symbol prescribed in paragraph 4.4.1. The requirements of Appendix A clause 6.2 must be met, except that instead of “longitudinally and rearwards to the upper part of the seat-back frame through a component simulating the back of the manikin shown in (Appendix A) annex 3”, a force producing a moment of 53 daNm in relation to the R point may be applied directly to the upper cross member of the seat-back in a rearward longitudinal direction either: 6.3.1.                              horizontally; or. 2. "Locking system" means a device ensuring that the seat and its parts are maintained in the position of use; 2.9. No failure shall be shown in the seat frame or in the seat anchorage, the adjustment and displacement systems or their locking devices during or after the tests prescribed in paragraphs 6.2. and 6.3. ..................... 1. Hence, it is easy to use the toilet. 2b. Apply a 100 " 10 N load to the back and pan assembly of the 3-D H machine at the intersection of the hip angle quadrant and the T‑bar housing. The competent authority which granted type approval may at any time verify the conformity control methods applied for each production unit. The back and seat pans are constructed of reinforced plastic and metal; they stimulate the human torso and thigh and are mechanically hinged at the "H" point. However, if the vehicle is equipped with one or more seats fitted or capable of being fitted with head restraints, approved as meeting the requirements under paragraphs 5.1. and 5.2. below, the number of this Regulation shall be followed by the letters "RA". For integrated head restraints, the limit between the head restraint and the seat-back is defined by the plane perpendicular to the reference line 540 mm from the R point. During the rocking action, the T‑bar of the 3-D H machine may tend to diverge from the specified horizontal and vertical alignment. In the case of seats (benches) with more places to sit than head restraints, the test described in paragraph 6.2. shall be carried out. This Regulation applies to the strength of seats, to their anchorages and to their head restraints, of vehicles of categories M1 and N, and to the strength of seats, to their anchorages and to their head restraints, of vehicles of categories M2 and M3, not covered by Regulation No. "Torso‑line" means the centreline of the probe of the 3-D H machine with the probe in the fully rearward position; 2.6. The requirements of paragraphs 5.4.2. and 5.4.3. above, shall not apply to parts of rear faces of head restraints designed to be fitted to seats behind which no seat is provided. 1.2.1. During this lifting, the feet are to be free to rotate; and no forward or lateral loads are to be applied. Each load must be applied ‘Forward’ of the seat back not more than 5o above or below the horizontal, and not more than 5o to left or right of the longitudinal axis of the vehicle. Where other modes of seat adjustment exist (vertical, angular, seat‑back, etc.) The distance "h" from the R point to the tangent S is the height to be taken into consideration in implementing the requirements of paragraph 5.5. above. 17 with regard to the strength of any seats on the vehicle which are not fitted or capable of being fitted with head restraints. Head restraints fitted as standard equipment for vehicles equipped with such parts or devices shall be considered as part of the partitioning system. Figure - Three-dimensional reference system, REFERENCE DATA CONCERNING SEATING POSITIONS. General specifications applicable to seats of vehicles of categories N1, N2 and N3 and to seats of vehicles of categories M2 and M3 not covered by Regulation No. Through this system all students can be properly seated for optimal ergonomic/work performance. When making a garden bench a good way to work out a comfortable height is to find a seat you find comfortable and take its height measurements. Date  .................................................................... 20. When there is a gap, allowing sliding of one type 1 block past the seats, then the test loads (two type 1 blocks) shall be installed behind the seats after agreement between the Technical Service and the manufacturer.
