Seat frame structure carrying level-control function

Abstract

Abstract PURPOSE:To give mechanical strength to a seat cushion and thereby lighten the load on the whole body, by making a coupling device for a lift link support a seat cushion free of rotation. CONSTITUTION:A seat lifter 12 is constituted of frontward holding plates 20a, 20b and rearward holding plates 21a, 21b all being installed in front and in the rear of an upper rail 176, and frontward lift links 18a, 18b supported on these frontward holding plates 20a, 20b by means of shafts 28a, 28b as well as rearward lift links 19a, 19b pivoted on these rearward holding plates 21a, 21b by means of shafts 28a, 28b. Each interval between these frontward lift links 18a, 18b and rearward lift links 19a, 19b is coupled with torque rods 25 and 26. And, an actuating rod 24 is pivoted on the rearward lift link 19a, while a turning position adjusting device 29 is attached to the front lift link 18a, and a seat cushion is rotatably supported by these torque rods 25 and 26.
