Infant carrier and car safety seat with no-rethread harness adjustment
First Claim
1. A mechanism for positional adjustment of shoulder harness belts for use with a child safety seat without rethreading of the shoulder harness belts through a seatback of the child safety seat, the seatback comprising at least one slot through which a shoulder harness belt extends, the at least one slot in the seatback defining a lengthwise dimension in an axial direction, the mechanism comprising:
- a carrier plate movable along guide channels extending axially along a back face of the seatback wherein the carrier plate includes at least one opening positioned for receiving the shoulder harness belt extending through the at least one slot in the seatback; and
a positioning member pivotally coupled to the carrier plate, the positioning member defining at least one harness belt slot positioned for receiving the shoulder harness belt extending through the at least one opening in the carrier plate.

Abstract
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.

- 11. A carrier plate for providing height adjustment to a shoulder harness belt of a child safety seat, the carrier plate being movable along a seatback of the child safety seat whereby the position of the shoulder harness belt can be adjusted, the carrier plate comprising a guide portion extending axially along each side of the carrier plate for sliding within guide channels positioned along the seatback, the carrier plate further comprising a pivotally mounted positioning member having a harness belt slot for receiving the shoulder harness belt, whereby the carrier plate is movable along the seatback when the shoulder harness belt is not taut, and whereby the positioning member engages the seatback such that the carrier plate is fixed in position relative to the seatback when the shoulder harness belt is taut, wherein the seatback of the child safety seat defines a seatback slot extending therethrough, and wherein the shoulder harness belt extends through the harness belt slot of the positioning member, through an opening in the carrier plate, and through the seatback slot.
- 13. A carrier plate for providing height adjustment to a shoulder harness belt of a child safety seat, the carrier plate being movable along a seatback of the child safety seat whereby the position of the shoulder harness belt can be adjusted, the carrier plate comprising a guide portion extending axially along each side of the carrier plate for sliding within guide channels positioned along the seatback, the carrier plate further comprising a pivotally mounted positioning member having a harness belt slot for receiving the shoulder harness belt, whereby the carrier plate is movable along the seatback when the shoulder harness belt is not taut, and whereby the positioning member engages the seatback such that the carrier plate is fixed in position relative to the seatback when the shoulder harness belt is taut, 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 mechanism for positional adjustment of shoulder harness belts for use with a child safety seat comprising a seatback including at least one slot defining a lengthwise dimension in an axial direction, the mechanism comprising:
-
a carrier plate movable along guide channels extending axially along a back face of the seatback; a positioning member pivotally coupled to the carrier plate, the positioning member defining at least one harness belt slot; at least one harness belt extending through the at least one slot in the seatback and through the at least one harness belt slot of the positioning member; and a spring for biasing the positioning member out of engagement with the guide channels to allow translation of the carrier plate relative to the seatback when the shoulder harness belt is not taut. - View Dependent Claims (18, 19)
