DEVICE IMPROVING OPERATION FORCE OF SEAT RAIL FOR VEHICLE

摘要

PURPOSE: A device improving operation force of a seat rail for a vehicle is provided to easily set seat positions of passengers and to improve quality of the seat rail by securing flexible operability. CONSTITUTION: An operation force improving device(40) for forming an artificial positioning groove to hold the exact position of a ball interposed in both bent units of lower and upper rails comprising a seat rail(30) of a vehicle and to prevent the separation of the ball and for improving the operability is composed of a plate-shaped base(41); a fixing block(42) set in the center of the base to hold the seat rail not to move; an operating cylinder(44) fixed to a bracket(43) set at both sides of the fixing block and operated to reciprocally slide the lower rail for the upper rail; and a pressurizing unit arranged above the fixing block to pressurize the seat rail at the same condition on a vehicle.
