shall not be possible to raise it beyond the maximum operational height except by deliberate action on the part of the user distinct from any act necessary for its adjustment.

         5.14. 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 6.4.3.6. 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.

         5.15.  Special requirements regarding the protection of occupants from displaced luggage

         5.15.1.  Seat-backs

            Seat-backs and/or head restraints located such that they constitute the forward boundary of the luggage compartment, all seats being in place and in the normal position of use as indicated by the manufacturer, shall have sufficient strength to protect the occupants from displaced luggage in a frontal impact.  This requirement is deemed to be met if, during and after the test described in annex 9, the seat-backs remain in position and the locking mechanisms remain in place.  However, the deformation of the seat-backs and their fastenings during the test is permitted, provided that the forward contour of the parts of the tested seat-back and/or head restraints, that are harder than 50 Shore A, does not move forward of a transverse vertical plane which passes through:

             (a) a point of 150 mm forward of the R point of the seat in question, for the parts of the head restraint;

             (b) a point of 100 mm forward of the R point of the seat in question, for parts of the seat-back;

         excluding the rebound phases of the test blocks.

         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.

         All measurements shall be taken in the longitudinal median plane of the corresponding seat or seating position for each seating position constituting the forward boundary of the luggage compartment.

         During the test described in annex 9, the test blocks shall remain behind the seat-back(s) in question.

5.15.2.  Partitioning systems

           At the request of the vehicle manufacturer, the test described in annex 9 may be carried out with the partitioning systems in place, if these systems are fitted as standard equipment for the particular type of vehicle.

           Partitioning systems, netting wire mesh located above the seat-backs in their normal position of use, shall be tested according to paragraph 2.2. of annex 9.

           This requirement is deemed to be met if, during the test, the partitioning systems remain in position.  However, the deformation of the partitioning systems during the test is
