Abstract

An infant car seat system includes an infant car seat with an integrated anchor system to conveniently secure the infant car seat to a vehicle seat, without using a detachable vehicle installation base and without using a vehicle seat belt. The anchor system is coupled to the infant car seat at one or more mechanical constraining points positioned based on the center of gravity of the infant car seat and respective anchor points at which the anchor system engages with vehicle lower anchors. The anchor system may be a rigid anchor system or a belted anchor system, and the system may include one or more of a release actuator for a quick disconnect mechanism, an adjustment foot to accommodate different vehicle seats and ensure a tight fit, and/or one or more storage compartments to store parts of the anchor system when unused. Such features render the infant car seat system particularly useful for ride-hailing and ridesharing services.

First claim

What is claimed is:

1. An infant car seat system for installation on a vehicle seat, comprising:
an infant car seat having a seat shell including a seat back, a seat pan, a first side with a first seat shell rail, a second side with a second seat shell rail, and a seat front that faces a vehicle seat back of the vehicle seat when the infant car seat is installed on the vehicle seat, the infant car seat being portable via a carrying handle while an infant is in the infant car seat, the carrying handle being attached to the first side of the seat shell via a first carrying handle attachment mechanism and the second side of the second side of the seat shell via a second carrying handle attachment mechanism;
a center of gravity of the infant car seat system disposed proximate an axis passing through the first carrying handle attachment mechanism and the second carrying handle attachment mechanism;
wherein the second seat shell rail spaced from the first seat shell rail to define a space therebetween, the first seat shell rail and the second seat shell rail extending from the seat shell in a direction away from the seat pan, wherein the first seat shell rail and the second seat shell rail directly support the infant car seat on the vehicle seat without using an infant car seat detachable base arranged between the first and second seat shell rails and the vehicle seat, and wherein the seat shell, the first seat shell rail, and the second seat shell rail form a unitary and non-separable structure, positions of the first seat shell rail and second seat shell rail being fixed relative to a remainder of the seat shell;
wherein the first carrying handle attachment mechanism and the second carrying handle attachment mechanism are disposed above portions of the first seat shell rail and the second seat shell rail in direct contact with the vehicle seat when the first seat shell rail and the second seat shell rail are supporting the infant car seat on the vehicle seat; and
an anchor system coupled to the seat shell and configured to attach the infant car seat directly to the vehicle seat without using an infant car seat detachable base, the anchor system comprising:
a first infant car seat anchor coupled to the infant car seat via a first belt portion, the first infant car seat anchor extending from the first side of the seat shell to an area outside of the space via the first belt portion, the first car seat anchor being mechanically engageable with a first vehicle anchor of the vehicle seat; and
a second infant car seat anchor coupled to the infant car seat via a second belt portion, the second infant car seat anchor extending from the second side of the seat shell to an area outside of the space via the second belt portion, the second car seat anchor being mechanically engageable with a second vehicle anchor of the vehicle seat.

2. The system of claim 1 , wherein the first belt portion extends from an area of the first side proximate a front of the seat shell, and wherein the second belt portion extends from an area of the second side proximate a front of the seat shell.

3. The system of claim 1 , wherein the first belt portion and the second belt portion are a single belt.

4. The system of claim 3 , wherein the single belt includes an intermediate portion that extends between the first belt portion and the second belt portion, the intermediate portion being disposed within at least one of the space and the seat shell.

5. The system of claim 1 , wherein the first belt portion extends from the first seat shell rail of the first side of the seat shell, and wherein the second belt portion extends from the second seat shell rail of the second side of the seat shell.

6. The system of claim 1 , wherein the first belt portion and the second belt portion are adjustable.

7. The infant car seat system of claim 1 , wherein:
the vehicle seat includes a pair of LATCH system lower anchors;
the first infant car seat anchor includes a first infant car seat LATCH system connector;
the first vehicle anchor is a first vehicle LATCH system anchor of the pair of LATCH system lower anchors of the vehicle seat;
the second infant car seat anchor includes a second infant car seat LATCH system connector; and
the second vehicle anchor is a second vehicle LATCH system anchor of the pair of LATCH system lower anchors of the vehicle seat.

8. The infant car seat system of claim 1 , wherein:
the vehicle seat includes a pair of ISOFIX system lower anchors;
the first infant car seat anchor includes a first infant car seat ISOFIX system connector;
the first vehicle anchor is a first vehicle ISOFIX system anchor of the pair of ISOFIX system lower anchors of the vehicle seat;
the second infant car seat anchor includes a second infant car seat ISOFIX system connector; and
the second vehicle anchor is a second vehicle ISOFIX system anchor of the pair of ISOFIX system lower anchors of the vehicle seat.

9. The infant car seat system of claim 1 , wherein the first side of the seat shell defines a first opening, and the second side of the seat shell defines a second opening, the first belt portion extending through the first opening to the area outside of the space, and the second belt portion extending through the second opening to the area outside of the space.

10. The infant car seat system of claim 9 , wherein the first belt portion and the second belt portion compose a single belt, the single belt extending from the first infant car seat anchor to the second infant car seat anchor through both of the first opening and the second opening.

11. The infant car seat system of claim 10 , wherein a portion of the single belt that extends between the first opening and the second opening is positioned within an interior of the infant car seat.

12. An infant car seat system for installation on a vehicle seat, comprising:
an infant car seat having a seat shell including a seat back, a seat pan, a first side with a first seat shell rail, a second side with a second seat shell rail, and a seat front that faces a vehicle seat back of the vehicle seat when the infant car seat is installed on the vehicle seat, the infant car seat being portable via a carrying handle while an infant is in the infant car seat, the carrying handle being attached to the first side of the seat shell via a first carrying handle attachment mechanism and the second side of the second side of the seat shell via a second carrying handle attachment mechanism;
a center of gravity of the infant car seat system disposed proximate an axis passing through the first carrying handle attachment mechanism and the second carrying handle attachment mechanism;
wherein first seat shell rail and the second seat shell rail extend from the seat shell in a direction away from the seat pan, wherein the first seat shell rail and the second seat shell rail directly support the infant car seat on the vehicle seat without using an infant car seat detachable base arranged on the vehicle seat, and wherein the seat shell, the first seat shell rail, and the second seat shell rail form a unitary and non-separable structure;
wherein the first carrying handle attachment mechanism and the second carrying handle attachment mechanism are disposed above portions of the first seat shell rail and the second seat shell rail in direct contact with the vehicle seat when the first seat shell rail and the second seat shell rail are supporting the infant car seat on the vehicle seat; and
an anchor system configured to attach the infant car seat directly to the vehicle seat without using an infant car seat detachable base, the anchor system comprising:
a first infant car seat anchor coupled to
