A child car seat has a seat back with an upper end and a head rest coupled to the seat back near the upper end. The head rest is vertically adjustable along the seat back between a raised position and a lowered position. The car seat has an adjustment mechanism with an actuator and a lock element. The lock element is movable between a locked condition preventing vertical adjustment of the head rest and an unlocked condition permitting vertical adjustment of the head rest. The actuator is actuable to reconfigure the adjustment mechanism between a locked arrangement blocking the lock element in the locked condition, a released arrangement unblocking the lock element from the locked condition, and an unlocked arrangement whereby the lock element is in the unlocked condition. |
