Disclosed is a gearing device for a seat including a first internally toothed gear, a second internally toothed gear, an externally toothed gear, and an eccentric member. The first internally toothed gear includes a rotation center axis. The second internally toothed gear has the rotation center axis in common with the first internally toothed gear and is rotatably supported by the first internally toothed gear. The externally toothed gear is arranged to an inner side of the first and the second internally toothed gear, to thereby mesh with the first and the second internally toothed gears. The eccentric member rotates the externally toothed gear such that a rotation center thereof follows a path around the rotation center axis, rotatably supports the externally toothed gear about the rotation center, and rotates about the rotation center axis in response to a rotational force being externally input thereto.

Gearing device for seat

An electric telescopic apparatus for a vehicle seat includes a base body provided at one of the vehicle seat or an ottoman, a movable body provided at a movable portion, the movable body assembled to the base body so as to extend or retract relative to the base body, a rack fixed on one of a top surface or a bottom surface of the base body or the movable body, the rack being formed in a plate shape which extends in the extending and retracting direction of the movable body and having teeth, a pinion housed in the other of the base body or the movable body and engaged with the rack, a drive unit for driving the pinion, and a guide mechanism provided at the base body and the movable body to guide the movable body in the extending and retracting direction of the movable body.

Electric telescopic apparatus for vehicle seat

A vehicle seat apparatus including a cushion body provided on a frame member, a seat cushion, a gear member, a driving mechanism, an arm, and a link mechanism having a first bracket rotatably supported at the gear member, a second bracket rotatably supported at the first bracket, and a link bracket, a first end of which is rotatably supported at the second bracket, and a second end of which is connected to the arm. The arm is connected to the gear member through the link mechanism, and with an up-and-down operation of a front-end portion of the cushion body relative to the frame member by means of a swing of the arm, a length of the seating surface is variable in a longitudinal direction.

Vehicle seat apparatus

A seat slide device for seat position adjustment, comprising: a lower rail arranged on an installing portion of a vehicle body; an upper rail retaining the seat and adapted to move along the lower rail; and an electric motor, so that the position of the seat may be adjusted by the lower rail, the upper rail and the electric motor through a drive unit. Further comprised is a bracket which has the drive unit arranged and is retained by the upper rail while retaining one end of a screw member arranged movably in the lower rail. The bracket includes an abutment face for abutting against a shoulder portion of one end of the upper rail below the top face of the same.

Seat slide device for vehicles

A driving force transmitting apparatus having a screw for connecting to a motor and a driven member, a nut member in threadable engagement with the screw, a holder containing the nut member for connection to a fixed member, a stopper limiting relative movement between the nut member and the screw, and an elastic member covering the entire outer surface of the nut member so the elastic member and the nut member form a single body.

Driving force transmitting apparatus

A seat for vehicles having a seat cushion and a seatback includes a seat cushion bracket mounted on both sides of the seat cushion, a seatback bracket mounted on both sides of the seatback, a lever rotatably pivoted on the seatback bracket, a cam member slidably supported on the seatback bracket and operatively connected to the lever, a locking groove formed on the seat cushion bracket and fixedly connectable with the cam member, and urging means interposed between the seatback bracket and the lever and always urging the lever so as to fixedly connect the cam member and locking groove.

Vehicle seat assembly

In order to realize that a seatback spring device can fit to the curvature of the back of an occupant, a sheet, preferably in the form of fabric, which is deformable in all directions is employed and is provided on a frame. Adjustable tension applying means are provided to adjust the seatback in both the lumbar area, and the shoulder area.
