Abstract
A walk-in device for use in a seat slide device is disclosed. The seat slide device includes a stationary rail, a movable rail slidably engaged with the stationary rail, and a locking mechanism for locking and unlocking the movable rail relative to the stationary rail when a first member is turned in first and second directions respectively. The walk-in device comprises a base member secured to the movable rail; a first lever pivotally connected to the base member, the first lever being turned between a first position wherein the first member is kept unchanged and a second position wherein a part of the first lever abuts against the first member to turn the same in the second direction; a second lever pivotally connected to the base member, the second lever having a projection which is slidably engageable with a side wall of the stationary rail under a certain condition; a link structure for providing a linkage connection between the first and second levers; and a spring for biasing the second lever in a direction to press the projection toward the stationary rail, wherein the link structure is so constructed that when the first lever assumes the first position, the second lever is prevented from turning, and when the first lever assumes the second position and the projection of the second lever is disengaged from an end of the stationary rail, the second lever is turned due to the force of the spring in a direction to suppress the turning of the first lever toward the first position.
