PURPOSE:To make level control for seating part depth and the front of a seat performable automatically in a way of interlocking with a longitudinal position adjusting motion in the seat, by using a support link mechanism and a driving cam mechanism installed between a seat frame and a seat cushion body. CONSTITUTION:A seating part 3 is attached to a seat frame 4 with a support link mechanism 5 retractably to or from the obliquely upper front. and, a driving cam mechanism 7 is installed in space between a floor fixed guide rail frame 10 of a seat 1 and a slide frame 11 slidably set up on this floor fixed guide frame 10. And, this driving cam mechanism 7 and the support link mechanism 5 are coupled together through a connecting rod 8. Then, the support link mechanism 5 is rocked by the driving cam mechanism 7 interlocking with longitudinal motion of the seat 1. With this constitution, the seating part 3 is made shiftable to the obliquely upper front. |
