A vehicle safety seat and infant carrier system allowing height adjustment of a shoulder harness strap without rethreading the harness strap through the seat. A positioning member is normally biased out of engagement with a toothed rail, allowing a harness strap carried by the positioning member to be adjusted up or down to fit the size of a child. As the harness strap is pulled tight, the positioning member is brought into engagement with the toothed rail, fixing the position of the strap relative to the seat.

The vehicle safety seat and infant carrier system of claim 11, wherein the positioning member is pivotally connected to the carrier plate at a lower portion of the positioning member, and wherein the at least one harness belt slot is positioned at an upper portion of the positioning member. 17. A method of adjusting a height of at least one shoulder harness strap of a vehicle safety seat without rethreading the shoulder harness strap through the vehicle safety seat, said method comprising tightening the shoulder harness strap to provide adjustment of the height of the shoulder harness strap while a positioning member is biased out of engagement with a toothed guiderail when the harness strap is not taut, and bringing the positioning member into engagement with the toothed guiderail when the harness strap is taut, and wherein tightening the harness strap pivots the positioning member to overcome a normal bias out of engagement with the toothed guiderail. 18. The method of claim 17, further comprising adjusting the height of a headrest along with the shoulder harness strap. 19. The method of claim 17, wherein the height of the at least one shoulder harness strap is automatically brought to the shoulder height of a child seated in the vehicle safety seat by tightening the harness strap. 20.
