ISOFIXLATCH

ISOFIXLATCH refers to the compatibility between two child car seat installation systems: ISOFIX (the European standard) and LATCH (Lower Anchors and Tethers for Children, used in the United States and several other regions). The term is often used to describe seats, vehicles, or installation instructions that support either system, or that can be converted between them.

ISOFIX uses fixed metal anchors embedded in the vehicle seat, typically with a corresponding top tether point. LATCH provides lower anchors in the seat bight and a top tether, with similar overall function to secure a child seat without using the vehicle’s seat belt. In practice, many modern child seats are designed to be compatible with both systems, allowing installation with ISOFIX anchors or with LATCH lower anchors, depending on the vehicle and the seat’s labeling.

When using ISOFIXLATCH-compatible seats, installers must follow the manufacturer’s instructions and common safety practices: choose a single installation method for a given seat, ensure the anchors and tether are properly attached, verify that the seat does not move more than a few centimeters at the belt path, and connect the top tether when required. Weight and age limits, as well as top tether requirements, vary by seat and vehicle, and may constrain which method is used.

Overall, ISOFIXLATCH emphasizes cross-compatibility and reduces installation errors by offering standardized anchorage options across different markets, while still requiring adherence to specific product manuals.
