Abstract
A walk-in apparatus for a seat of a vehicle, including an upper rail connected to the seat; a lower rail connected to a floor of the vehicle; a lead screw connected to the lower rail; a male helical gear connected to the lead screw, the male helical gear including external splines; and a female helical gear connected to the upper rail. The female helical gear includes internal splines configured to engage with the external splines of the male helical gear, and the male helical gear and the female helical gear are selectively separable. A torque transferred between the internal splines of the female helical gear and the external splines of the male helical gear when connected moves the upper rail relative to the lower rail.
