(Page 1, clause 2.1) Substitute the following for the existing clause: The following standards contain provisions which through reference in this text, constitute provision of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below: IS No Title 13749 : 2009 Automotive Vehicles Procedure for determining the H Point and the Torso Angle for 50 th percentile adult male in seating positions of motor vehicles (first revision) AIS 053:2005 Automotive Vehicles Types Terminology (Page 3, clause 4.3.1) Substitute the following for the existing clause: For the front seats of vehicles in categories M,N and L7, two lower belt anchorages and one upper belt anchorage shall be provided. However, for front central seats, two lower belt anchorages shall be considered sufficient where the wind screen is located outside the reference zone defined in 3.27. As regards the belt anchorages, the windscreen is considered to be a part of the reference zone if it is capable of entering into contact with the test apparatus according to the method described in 3.27. (Page 3, clause 4.3.2) Substitute the following for the existing clause: For outboard seating positions, other than front, of vehicles of categories M 1 and L7 two lower anchorages are allowed, where there exists a passage between a seat and the nearest side-wall of the vehicle intended to permit access of passengers to other parts of the vehicle. A space between a seat and the side-wall is considered as a passage if the distance between that side-wall, with all doors closed and a vertical longitudinal plane passing through the centre line of the seat concerned, measured at the R-point position and perpendicular to the median longitudinal plane of the vehicle is more than 500 mm.
For BIS use only Doc: TED 29(1056) (Page 3, clause 4.3.4) Substitute the following for the existing clause: If seat belts are provided by the vehicle manufacturer as original equipment fitment for the other outboard seats of the vehicle categories M 1 and L7, there shall be two lower belt anchorages if only 2-point lap belts are provided and additionally one upper belt anchorage if 3-point belts are provided. (Page 3, clause 4.3.5) Substitute the following for the existing clause: If seat belts are provided by the vehicle manufacturer as original equipment fitment for other seats in vehicle categories M 1 and L7 and all other non-protected seats in categories other than M 1 and L7 as given in 4.3.1, there shall be at least two lower belt anchorages. (Page 3, clause 4.4.2.2) Substitute the following for the existing clause: Front Seats, vehicle categories M 1 and L7 In motor vehicles of categories M 1 and L7,the angle α 1 (other than buckle side) shall be within the range of 30 to 80 and the angle α 2 (buckle side) shall be within the range of 45 to 80. Both angle requirements shall be valid for all normal travelling positions of the front seats, Where at least one of the angles α 1 or α 2 is constant (for example anchorage fixed at the seat) in all normal positions of use, its value shall be 60 ± 10. In the case of adjustable seats with an adjusting device as described in 3.18 with a seatback angle of less than 20 (see Fig. l ), the angle α 1 may be below the minimum value (30 ) given above, provided it is not less than 20 in any normal position of use. (Page 5, clause 4.4.2.3) Substitute the following for the existing clause: Rear seats, vehicle categories M 1 and L7-M In motor vehicles of categories M 1 and L7-M, the angles α 1 and α 2 shall be within the range of 30 to 80 for all rear seats.

In the case of vehicles having a maximum vehicle mass not exceeding 3.5 t, and at least one of the angles α 1 or α 2 is constant in all normal positions of use (for example anchorage fixed at the seat) and its value shall be 60 ± 10. (Page 5, clause 4.4.2.5) Substitute the following for the existing clause: Rear seats and special front or rear seats, vehicle categories other than M 1 and L7 In motor vehicles of categories other than M 1 and L7, in the case of:
For BIS use only Doc: TED 29(1056) a) bench seats; b) adjustable seats (front and rear) with an adjusting device as described in 3.18 with a seat back angle of less than 20 (see Fig. 1); and c) other rear seats. Angles α 1 and α 2 may be between 20 and 80 in any normal position of use. Where in the case of the front seats of vehicles having a maximum vehicle mass not exceeding 3.5 t, at least one of the angles α 1 or α 2 is constant in all normal position of use (for example, anchorage fixed at the seat), its value shall be 60 ± 10. In case of the seats, other than front seats, of the vehicle category M 2 and M 3, the angles α 1 and α 2 shall be between 45 and 90 for all normal position of use. (Page 7, clause 5.1.2) Substitute the following for the existing clause: The seats shall be fitted and placed in the position for driving or use chosen by the testing authority to give the most adverse conditions with respect to the strength of the system. The position of the seats shall be stated in the report.

(Page 8, clause 5.4.1.2) Substitute the following for the existing clause: A test load of 1 350 ± 20 dan shall be applied to a traction device (see Fig. 3) attached to the belt anchorages of the same belt, by means of a device reproducing the geometry of the upper torso strap of such a safety belt, in the case of vehicles of categories M 1 and N 1. The test load shall be 675 ± 20 dan for categories M 2,N 2 and L7 and 450 ± 20 dan for M 3 and N 3. (Page 8, clause 5.4.1.3) Substitute the following for the existing clause: At the same time, a tractive force of 1 350 ± 20 dan shall be applied to a traction device (see Fig. 4) attached to the two lower belt anchorages, in the case of vehicles of categories M 1 and N 1.The test load shall be 675 ± 20 dan for categories M 2, N 2 and L7 and 450 ± 20 dan for categories M 3 and N 3. (Page 8, clause 5.4.2.1) Substitute the following for the existing clause: A test load of 1 350 ± 20 dan shall be applied to a traction device (see Fig. 3) attached to the upper belt anchorage and to the opposite lower belt anchorage of the same belt, using, if supplied by the manufacturer, a retractor fixed at the upper belt anchorage, in the case of vehicles of categories M 1 and N 1.
