Abstract: A vehicle seat (10) has a lower seat frame (14) and a seat back (16) pivoted about a recliner axis (20). An occupant (22) restraining shoulder belt (26) has an upper attachment point provided by a sliding belt guide (40) fixed to the top of a resilient, flexible elongated tower (36) attached to one side of the seat back (16). The tower (36) is normally unflexed, with the same orientation as the seat back (16), but is capable of bending with the belt guide (40) down and forwardly relative to the seat back and closer to the recliner axis (20) when a forward and downward force is applied to the belt guide (40). An inertially locking belt retractor (24) is rigidly fixed to the seat (10) below the belt guide (40). The retractor (24) provides a reserve length of belt (50) that extends up along the back of the tower (36) and over the belt guide (40) and then continues into the shoulder belt (26).
