A method of configuring a vehicle seating assembly includes the step of providing a vehicle seating assembly that has a seat rotational member that rotatably couples a lower leg support to a seat and a seatback rotational member that rotatably couples the seat to a seatback. The method further includes the step of receiving input of a user's desired configuration of the vehicle seating assembly. The method still further includes the step of actuating at least one of the seat rotational member and the seatback rotational member responsive to the input received.

A vehicle seat includes a seat cushion frame provided at a seat cushion; a seatback frame structuring a seatback, the seatback frame being rotatably coupled to a front-rear direction rear end portion of the seat cushion frame via a rotation axle; a drive unit disposed at a front-rear direction front side of the seat cushion frame; and a first driving force transmission unit that couples the drive unit with the rotation axle and transmits driving force of the drive unit to the rotation axle.

The invention relates to an active vehicle seat suspension system with a lower part and an upper part of a vehicle seat and a scissor frame arranged therebetween with at least one first and at least one second scissor arm articulatedly connected thereto, wherein at least the first scissor arm is articulatedly connected with a first end to the upper part and is articulatedly connected with a second end to the lower part and is displaceable thereon, wherein at least one traction means which can move the second end of the first scissor arm forwards or backwards, as viewed in the longitudinal direction of the vehicle seat, is firmly connected to at least one rolling axle which is arranged at the second end.

An adjusting mechanism includes a driving gear, a first toothed plate, a second toothed plate, and a reset assembly. The first toothed plate is provided with a first tooth-shaped structure, and the second toothed plate is provided with a second tooth-shaped structure; the first tooth-shaped structure and the second tooth-shaped structure are arranged side by side, and both the first tooth-shaped structure and the second tooth-shaped structure mesh with the driving gear; and the reset assembly is arranged between the first toothed plate and the second toothed plate, and is configured to allow the second toothed plate to tend to rotate relative to the first toothed plate.

A vehicle seat including: a seat cushion; a seat lifter including a link which connects the seat cushion and a base on a vehicle body and is configured to rotate about an axis extending in a seat width direction and configured to adjust a height of the seat cushion with respect to the vehicle body by the rotation of the link; and a fixture for fixing a seat belt which is abutted and attached to a mounting surface portion of the link, the mounting surface portion being formed on an outer surface portion of the link and obliquely facing a front side.

Disclosed herein is a pumping apparatus for a vehicle seat, which includes an input member rotated by torque input from a handle lever, a clutch unit configured to transmit the input torque to a link mechanism of a seat cushion, a brake unit configured to cut off the torque input in reverse from the link mechanism, a housing accommodating the clutch unit therein, and a fixing member coupled to a rear end of the housing, wherein the input member includes a first input member disposed in front of the housing, and a second input member connected to the first input member and accommodated in the housing, and the clutch unit includes a torque transmission member arranged on an outer peripheral surface of the second input member, and an annular control member having a clutch friction surface formed on an inner peripheral surface thereof.

A vehicle seating assembly is provided which includes a seat back and a seat base operably connected to the seat back. The seat base has a seat base frame that includes a torsion tube extending laterally between at least two side members. A height adjustment mechanism is disposed through at least one of the side members. A torsion spring extends within the torsion tube and is in contact with at least two side members. A torsion spring bushing is positioned around the torsion spring and extends into the torsion tube. The torsion spring bushing defines a brush configured to contact the torsion tube and a retaining ring positioned around the torsion tube. The retaining ring is in contact with at least one side member.

Disclosed is a seat pumping device for a vehicle. The seat pumping device includes: a housing; a return spring guide which is fixedly coupled to the housing and has an embedded return spring; a clutch cam which is rotatably accommodated in the housing; and a lever bracket which is partially accommodated in the return spring guide and coupled to the clutch cam so as to be rotated integrally with the clutch cam, in which the lever bracket is maintained spaced apart from the return spring guide by a separation support means, thereby improving operating characteristics of a lever handle.

A slide rail includes a fixed-side rail, a movable-side rail, and a reinforcing structure that prevents detachment of the movable-side rail from the fixed-side rail. The reinforcing structure includes a fixed-side engaging portion attached to the fixed-side rail, and a movable-side engaging portion attached to the movable-side rail. The fixed-side and the movable-side engaging portions are configured, while allowing sliding of the movable-side rail, to come in contact with each other due to an action by a large load in a detaching direction input between the fixed-side rail and the movable-side rail, and to be engaged with each other to restrict movement of the movable-side rail in the detaching direction. A contact surface, that comes in contact with the movable-side engaging portion, of the fixed-side engaging portion includes surface regions that have mutually different positions in the detaching direction and are provided side by side in a sliding direction.

An actuator includes a pinion engaging a seat height adjustment mechanism. A brake drum fixed to the seat defines an outer brake race. A brake hub integrated with the pinion, rotatable in the brake drum, defines an inner brake race. Rolling brake elements between the brake races lock the brake hub to the brake drum in the absence of actuator input. A clutch drum covers the brake races, defines an outer clutch race, and includes clutch tabs to displace the rolling brake elements, unlocking the brake hub, responsive to actuator input. A driver cam rotatable within the clutch drum defines an inner clutch race. Rolling clutch elements in the clutch races transmit actuator input to the clutch drum and permit rotation of the driver cam relative to the clutch drum in the absence of actuator input. An exterior cup fixed to the brake drum defines a housing for the actuator.
