Abstract
A latching mechanism for a car seat that is mountable on a separable base member provides a positive locking of the car seat to the base member. The latch mechanism has a member that is positioned in the seat portion of the car seat to pivot upwardly when the latch mechanism is disengaged. The seating of a child on the seat portion requires the latch mechanism to be retracted into the seat portion, which corresponds to the locking of the latch mechanism. The latch mechanism includes four helical spools rotated by the pivotal movement of the latch lever to cause linear movement of the locking pins into engagement with the base member. A latch indicator has a pre-latch sensor that indicates proper positioning of the seat member and a latch sensor that indicates an engagement of the locking pins. An indicator light illuminates when the seat member is properly latched.
