Seat track

摘要

The present invention relates to a seat track comprising a fixed rail of a channel structure having laterally inner walls which extend vertically and have recesses; a moving rail sliding along the fixed rail and having laterally vertical walls which face the inner walls of the fixed rail and have a plurality of through holes; and a locking member having a supporting body received and installed between the vertical walls of the moving rail to face a plurality of the through holes, a plurality of rotating pins supported by the supporting body and rotating between a locking position where a plurality of the rotating pins are inserted in the recesses of the fixed rail through the through holes and an unlocking position where a plurality of the rotating pins are separated from the recesses, a guide spring supported by the supporting body and pressing a plurality of the rotating pins to rotate toward the unlocking position, and an unlocking body sliding along the supporting body due to an outer force to press a plurality of the rotating pins to rotate from the locking position to the unlocking position. Therefore, miniaturization and performance improvement can be accomplished compared to conventional technology.

1. A seat track comprising:
a fixed rail of a channel structure having laterally inner walls which extend vertically and have recesses with a predetermined interval in a longitudinal direction; a moving rail sliding along the fixed rail and having laterally vertical walls which face the inner walls of the fixed rail and have a plurality of through holes with a predetermined interval in the longitudinal direction; and a locking member having a supporting body received and installed between the vertical walls of the moving rail to face a plurality of the through holes, a plurality of rotating pins supported by the supporting body and rotating between a locking position where a plurality of the rotating pins are inserted in the recesses of the fixed rail through the through holes and an unlocking position where a plurality of the rotating pins are separated from the recesses, a guide spring supported by the supporting body and pressing a plurality of the rotating pins to rotate toward the unlocking locking position, and an unlocking body sliding along the supporting body due to an outer force to press a plurality of the rotating pins to rotate from the locking position to the position, wherein a plurality of the rotating pins are provided as a pair at both lateral sides and supported by the supporting body to rotate in the opposite directions therebetween, and also provided to be inserted into the recesses of the inner walls of the fixed rail through the through holes of the vertical walls of the moving rail.
