Abstract

A vehicle occupant restraint device (10, 120, 160) includes a three-point seatbelt device (20), a shoulder belt anchor (36), and a mover device (50, 124). The three-point seatbelt device (20) includesa shoulder belt (22A) extending from an upper portion on one seat width direction end side of a seatback (16) configuring a vehicle seat (12) on which an occupant (P) sits, toward a buckle (32) at alower portion on another seat width direction end side. The shoulder belt anchor (36) is provided for the shoulder belt (22A) to pass through at a shoulder opening (34) on the one seat width directionend side of an upper section of the seatback (16). The mover device (50, 124) moves the shoulder belt anchor (36) toward a top-to-bottom direction lower side of the seatback (16) when the seatback (16), which is configured to tilt rearward from an upright state, has been tilted rearward by at least a predetermined angle or greater with respect to a vertical direction.
