Proposal to introduce provisions for ISOFIX in convertible cars, to exempt vehicles with one seating position per row from the ISOFIX provisions of UN R14 and to correct an editorial error in Supplement 4 to the 07 series of the regulation, as adopted by the Working Party on Passive Safety (GRSP) at its 54th session. This proposal supersedes the earlier proposal submitted to WP.29 (document WP.29/2014/34) which was returned by WP.29 to GRSP for further consideration.
