12、obile Standards Committee at the request of the Department of Transport. Whilst it is permissible for seat belt booster cushions to be used with a lap belt in the centre front seat, in vehicles where these are fitted, or in the rear seats, it should be noted that the amount of protection provided by
13、 such devices is not as great as when they are used with a lap and diagonal seat belt. For a child, the greatest protection is provided by an approved harness or safety seat. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are res
14、ponsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 22, an inside back cover and a back cover. This standard has
15、 been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

16、83 BSI 02-20001 1 Scope This British Standard specifies requirements for seat belt booster cushions that are for use with a lap seat belt, a lap and diagonal seat belt or a child safety harness which carries a BSI Kitemark, an “E” Mark or an “e” Mark. These cushions are intended for use by persons o
17、f small stature (of mass 15 kg or more) occupying forward facing seats of motor vehicles for the purpose of improving the fit of the seat belt and therefore the protection against injury. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitio
18、n For the purposes of this standard the following definition applies. booster cushion a firm cushion that can include an integral back above the seating plane, designed for a person of small stature to sit on to improve the fit of an approved1) lap seat belt, lap and diagonal seat belt or a child sa
19、fety harness. It is restrained by either the seat belt or child safety harness or by a separate means. It may also, as appropriate, incorporate design features to improve the lie of the seat belt 3 Performance 3.1 General 3.1.1 The booster cushion shall be so designed and constructed that, when corr
20、ectly installed and properly used by an occupant, the seat belt will operate satisfactorily and reduce the risk of bodily injury in the event of an accident. The booster cushion shall be restrained against forward movement directly by the adult seat belt or a separate restraining device, and not by
21、the occupant except where a back is provided. In this case the total mass of the device shall not exceed 2 kg and the height of the back shall be not less than 600 mm above a horizontal surface when the device is resting on that surface with the back vertical and without load. 3.1.2 The booster cush
22、ion shall not have any sharp edges or other features liable to cause injury to the person seated on it or other occupants of the vehicle or to damage the seat belt. 3.1.3 The booster cushion shall be so designed and constructed that the occupant is released solely by release of the seat belt and tha
23、t this is not prevented by the booster cushion trapping any part of the seat belt assembly. 3.2 Dynamic test 3.2.1 The booster cushion shall be tested in accordance with Appendix A and shall comply with 3.2.2 to 3.2.4. 3.2.2 At no time during the test described in Appendix A shall the forward moveme
24、nt of the hip pivot of the manikin exceed 150 mm. The maximum forward movement of the manikin at the chest level shall exceed the maximum forward movement of the hip pivot, but shall not exceed 300 mm. 3.2.3 In side elevation, the lap belt, where it passes over the manikin installed as described in
25、Appendix A, shall be at an angle greater than 45 to the horizontal. 3.2.4 The booster cushion shall remain substantially in position during the test. 4 Instructions and information Each booster cushion shall be accompanied by the following instructions and information: a) the statement that “when us
26、ed in accordance with these instructions the booster cushion allows an approved adult seat belt or child safety harness to be used by a person of small stature”; b) the mass range for which it is intended; c) the correct method of installing the booster cushion; and the seating positions for which i
27、t is intended; d) the importance of ensuring that the lap strap is worn immediately below the stomach and across the tops of the thighs and also the desirability of wearing the straps tightly; e) the method recommended for cleaning the booster cushion; f) a general warning to the user of the danger
28、of making any alterations to the booster cushion without the approval of the manufacturer; g) a warning that the booster cushion should not be used if it is damaged or if it has been subjected to accident loads even if damage is not obvious; h) a warning that an ordinary loose cushion should not be
29、substituted for, or used with, a booster cushion. 1) An approved seat belt is one that carries a BSI Kitemark, an “E” Mark or an “e” Mark (see clause 1).

30、5:1983 2 BSI 02-2000 5 Marking Each booster cushion complying with this British Standard shall be permanently and indelibly marked with the following: a) the number of this British Standard, i.e. BS AU 1852); b) the name, trade mark or other means of identification of the responsible manufacturer; c
31、) the mass range for which it is intended. 2) Marking BS AU 185 on or in relation to a product is a claim by the manufacturer that the product has been manufactured to the requirements of the standard. The accuracy of such a claim is therefore solely the manufacturers responsibility. Enquiries as to
32、 the availability of third party certification to support such claims should be addressed to the Director, Quality Assurance Division, BSI, Maylands Avenue, Hemel Hempstead, Herts HP2 4SQ for certification marks administered by BSI or to the appropriate authority for other certification marks.

34、 and seat belt anchorages described in Appendix B. Fit a reference seat belt as described in Appendix C to the seat belt anchorages. Use a new seat belt for each test. A.2 Seat the dressed manikin specified in Appendix D on the booster cushion and fit the seat belt to the manikin as follows. Remove
35、the upper anchor plate of the seat belt from the test anchorage C and fit it to setting anchorage D. Firmly adjust the seat belt to the manikin but in such a way that the compression of the test seat cushion is not more than 10 mm. Without further adjustment of the seat belt, refit the upper anchora
36、ge plate to the test anchorage position. A.3 Propel the trolley in such a way that the velocity change is 50 + 0, 2 km/h and the manikin remains stable. Decelerate the trolley using either the apparatus described in Appendix E or any other device giving equivalent results. This apparatus shall meet
37、the performance requirements specified in Appendix F. A.4 Check that the booster cushion has not damaged the seat belt or the manikin. A.5 Check that release of the seat belt is not prevented by the booster cushion trapping any part of the seat belt assembly. Table 1 Characteristics of polyurethane
