A motor vehicle seatbelt restraint arrangement including a continuous seatbelt. When the occupant is seated the seatbelt buckle tongue is drawable across the body to engage the buckle providing firstly a pre-impact configuration of the seatbelt characterised by a lap belt portion resting on the hips or upper legs of the occupant, wherein the lap belt portion is rearward vertically offset relative to an underside belt portion of the continuous seatbelt across the seating surface of the seat, and secondly an impact configuration of the seatbelt characterised by the lap belt portion and the underside belt portion being less rearward vertically offset and substantially vertically aligned one with respect to the other to provide a more vertically aligned loop of the continuous seatbelt around the hips or upper legs of the occupant at impact preventing submarining of the occupant out from the motor vehicle seat during impact.
