Claims

[Scope of utility model registration request]

A seat track including a lower rail to be assembled to the floor of the vehicle body, an upper rail that is slidably fitted to the lower rail in the longitudinal direction and to which the seat is assembled, and a plurality of engagement parts fixed to the lower rail and arranged in the longitudinal direction. a seat track handle which is rotatably assembled to the upper rail and located along the longitudinal direction of the upper rail; and a seat track handle which is fixed to the middle part of the handle and whose rotation engages each engaging portion of the lock plate. A lock mechanism includes a lock lever that can be engaged and detached from the lock lever and a spring member that biases the lock lever in a direction to engage the lock plate; an open lever attached to the seat for disengaging the lock lever from the lock plate; and the open lever is connected to the seat back side of the seat, and as the open lever is tilted forward, the open lever is rotated to engage the lock lever. A seat slide device comprising a walk-in mechanism equipped with a connecting member that is flexible and has an engagement hole that opens in the vertical direction on the upper rail and a protrusion that projects downward for a predetermined length and is elastically deformable in the vertical direction. A plate is fixed so that the plate projects above the open lever, and the open lever is provided with a first engagement protrusion on its upper part that engages and disengages with the engagement hole of the flexible plate, and a side portion thereof. a second lock lever that engages and disengages from the lock lever;
Engaging protrusions are provided to bias the open lever in the non-engaging direction of both of the engaging protrusions, while the lock plate has a protrusion on the flexible plate that protrudes upward at a predetermined portion at the rear thereof. A seat slide device with a walk-in mechanism, characterized in that a protrusion is provided that engages with the plate and deflects the plate upward.
