US Patent 7207628 Infant car seat with adjustable base platform

An infant car seat with an adjustable base platform provides a variable angle of tilt for the seat. The base platform has a visual indicator showing the degree of tilt that has been selected. This visual indicator can include a clear plastic window in the base platform, through which a number or other symbol indicating the degree of tilt can be seen. The user can adjust the degree of tilt by depressing a button to disengage a locking mechanism, allowing the user to vary the degree of tilt until the desired degree of tilt is indicated on the visual indicator.
