A walk-in mechanism is provided to a seat, which includes an extension coil spring. One end of the extension coil spring is engaged with a first support element fixed to a floor, while another end thereof is engaged with a second support element fixed to the seat. The walk-in mechanism further includes a connecting element for operatively connecting such another end of extension coil spring with a seat back of the seat. Forward and backward movement of the seat causes movement of both of the second support element and another end of extension coil in forward and backward directions. Also, with forward inclination of the seat back, such another end of extension coil spring is moved backwardly via the connecting element. Hence, a tensile force of the extension coil spring is increased and decreased to allow a user to easily move the seat to either of walk-in position and normal use position.
