A vehicle safety belt system of the lap and shoulder type comprises a main belt (20) wound on a retractor (18), the free end of the belt being securable to the vehicle body work, a slidable tongue (22) fitted to said main belt (20) and a main buckle securable to the vehicle body work into which the tongue (22) is lockingly insertable. The retractor (18) includes means to prevent the main belt (20) from being withdrawn from the retractor (18), when the retractor (18) is subjected to an acceleration or deceleration in excess of a predetermined value. Mounting means on the retractor (18) are engageable with holding means (16) securable on the rear of a vehicle seat back (14) to position the retractor at or adjacent the top of the vehicle seat back (14). The system is also provided with releasable securing means (24, 26, 28, 30) associated with said retractor (18) to prevent the retractor (18) from moving forwardly in the event of an accident, but being releasable to allow the seat back (14), and with it the retractor (18), to be folded forward when desired. <MATH> |
