Patent attributes
A seat track slide device includes a pair of seat tracks. Each seat track has a lower rail, an upper rail, a lock lever, and a handle and is capable of switching the associated upper rail to locking and unlocking states by selectively engaging and disengaging the lever with respect to the lower rail. Each lever is inserted into the corresponding upper rail and pivotally supported in the upper rail. An interlock support portion of the lever projects into an outer zone with respect to the front end of the upper rail. The interlock support portion of the lock lever supports an interlock support portion of the handle pivotally relative to each other. With the lever maintained in the locking state, the handle is allowed to pivot relative to the lever in the outer zone with respect to the front end of the upper rail against elastic force produced by a torsion coil spring arranged in the upper rail.
