Abstract
A seat slide mechanism for vehicles has a lock plate which is disposed to prevent the lock plate from being turned in a direction of releasing an engagement of the lock plate with a lower rail due to a load applied to the upper rail when they are engaged. The vertical wall of the upper rail is disposed between second flange walls in close relation to one of the second flange walls of the lower rail and the lock plate is disposed between the other second flange wall and the vertical wall in close relation to the other second flange wall.
Claims13
A seat slide mechanism for a vehicle, comprising:
- a lower rail fixable to a floor of a vehicle and having a U-shaped cross section, the lower rail including a pair of downwardly extending first flange walls, one of the first flange walls having teeth;
- an upper rail attachable to a seat of the vehicle and supported for free sliding movement on said lower rail, said upper rail having an inverted T-shaped cross section and including a pair of upwardly extending second flange walls;
- a lock plate disposed between said lower rail and said upper rail, said lock plate including a lateral flange provided with a hole, said lock plate being operable between one position in which the hole engages one of the teeth to limit sliding motion of said upper rail relative to said lower rail and another position in which the hole is disengaged from the teeth to permit sliding motion of said upper rail relative to said lower rail;
- an operating lever operatively associated with said lock plate for operating said lock plate from said one position to said another position to permit sliding motion of said upper rail with respect to said lower rail;
- and
- said upper rail including a vertical wall disposed between said first flange walls of said lower rail, said vertical wall being located closer to one of said first flange walls than the other first flange wall, said lock plate being rotatably supported on the vertical wall of the upper rail by a pin, with the lock plate being positioned between the vertical wall of the upper rail and the other first flange wall.

A seat slide mechanism for vehicles comprising:
- an upper rail having an inverted T-shaped cross section, said upper wall including a vertical wall, a horizontal wall, and a pair of first flange walls which extend upwardly from ends of the horizontal wall;
- a lower rail having a U-shaped cross section, said lower wall including a bottom wall, a pair of side walls, and a pair of downwardly extending second flange walls each formed at an end of one of the side walls;
- a lock plate rotatably supported on said upper rail and engageable with said lower rail through rotational movement of the lock plate;
- said horizontal wall of said upper rail being disposed between the side walls of said lower rail, with said first flange walls of said upper rail being positioned in opposing relation to said second flange walls of said lower rails, and with said upper rail being slidably supported with respect to said lower rail;
- said lock plate being engageable with said lower rail to restrict said upper rail from sliding with respect to said lower rail and being disengageable from said lower rail to permit said upper rail to slide with respect to said lower rail;
- said vertical wall of said upper rail being disposed between said second flange walls of the lower rail;
- a pin which penetrates through a hole formed in said vertical wall of said upper rail and a hole formed in said lock plate;
- a projection formed on a first side surface of said lock plate, said projection being positioned in the hole in said vertical wall of said upper rail;
- and
- a recess formed in a second side surface of said lock plate that is opposite said first side surface, said pin having a head positioned in the recess in the second side surface of said lock plate.
