A seat apparatus for a vehicle includes a seat portion having a seat cushion, a seat slide mechanism for adjusting the position of the seat portion back and forth, and a lock mechanism adapted to effect locking engagement of the seat portion with a striker fixedly arranged relative to the floor of the vehicle, with the locking engagement being adapted to be released at a predetermined fixed position of the seat portion. A first operational mechanism is provided for operating the lock mechanism and is adapted to be operated from the rear side of the seat portion, and a second operational mechanism is provided for adjusting the position of the seat portion and is adapted to be operated from the front side and the rear side of the seat portion.

In a seat sliding device, an upper rail slidably moveable relative a lower rail interlocks with the lower rail upon movement of the upper rail away from the lower rail. An upwardly inclined portion and a downwardly inclined portion can be provided on the upper rail and the lower rails, respectively. A spacer element is provided between the upwardly inclined portion of the upper rail and a corner of the lower rail. The inclined portions and the spacer elements interlock upon movement of the upper rail away from the lower rail. Due to sufficient area being provided between the interlocking portions, separation of the upper rail from the lower rail can be prevented.

Seat sliding device

A spring coupler comprises a casing, a drive member rotatably mounted within the casing including a main portion and a core portion fixedly connected thereto by staking manner, a driven member rotatably mounted within the casing including a main portion and a core portion fixedly connected thereto by stacking manner and engageable with the core portion of the drive member upon rotation thereof, and a coil spring disposed between the drive member and the casing so as to be engaged frictionally with the casing in the free state thereof and including a first tang and a second tang. In this spring coupler, the first tang and the second tang of the coil spring are engaged with the core portion of the drive member in rotation in one direction and the other direction respectively before the drive member is brought into engagement with the core of the driven member thereby reducing the radius of the coil spring whereas the first tang and the second tang of the coil spring are engaged with the core portion of the driven member in rotation in one direction and the other direction respectively, thereby expanding the radius of the coil spring. The main portion and the core portion are fixedly connected with each other by staking manner so that less time and less cumbersome operations are required for assembling the drive member and/or the driven member.
