FORT MILL, S.C. — Manufacturer Combi USA says it's voluntarily recalling 67,000 child car seats because federal tests show the seats might separate from their bases in front-end collisions.

The Fort Mill, S.C.-based company said yesterday in a release it has received no reports of injuries involving the recalled seats.

In a letter to consumers, the company says the recall involves its Centre, Centre ARB and Shuttle seats, as well as the travel systems containing the Centre and Shuttle seats. The recall covers seats produced between October 2005 and December 2007.

Consumers are being asked to contact the company to obtain a free retrofit kit on its Web site or by calling 800-543-7734.
