Infant carrier and car safety seat with no-rethread harness adjustment

摘要

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.
