Abstract: In certain embodiments, a method includes forming, on a substrate by spin-on deposition, a layer stack of alternating layers of first and second carbon-containing materials. The layers of the first carbon-containing material include an agent-generating ingredient for generating a solubility-changing agent in response to an activation trigger. The method includes executing the activation trigger in response to which the solubility-changing agent is generated from the agent-generating ingredient in the layers of the first carbon-containing material and modifies the layers of the first carbon-containing material to be soluble in a developer. The method includes etching first openings through the layer stack, filling the first openings with a third material, etching second openings through the layer stack, removing the layers of the first carbon-containing material from the layer stack by exposing those to the developer, and replacing the layers of the first carbon-containing material with a fourth material.

Abstract: A seat rail for a vehicle includes: a rail gap cover combined with a moving rail, and a slit cover combined with the rail gap cover to close the gap between a fixed rail and the moving rail regardless of movement of the moving rail, whereby it is possible to prevent foreign substances from entering into the fixed rail.

Abstract: A vehicle seat frame is proposed. The vehicle seat frame includes: a base frame arranged at a vehicle seat, having a placing space therein; a lock pin lever formed at a center portion of the placing space; an inside gear configured to rotate along an inner surface of the placing space in an operation of the lock pin lever; a gear plate arranged at a lower end of the base frame and an outside gear formed along an outer circumferential surface thereof, wherein when the lock pin lever is operated, the outside gear is engaged with the inside gear of the base frame so that the inside gear rotates.

Abstract: The present disclosure provides a seat recliner for a vehicle. The seat recliner includes: a lower plate; a rotary flange that has a ring shape, is fitted around the lower plate to relatively rotate to the lower plate, and has inner teeth around the inner side of the rotary flange; locking gears that are disposed on the top of the lower plate, have outer teeth at an end, and engage with inner teeth of the rotary flange when moving forward; locking guides that are disposed between the locking gears and guide the locking gears moving forward and backward; and an upper plate that covers the locking gears and the locking guides, rotates relative to the rotary flange. In particular, a bottom of the locking guides is fixed to the top of the lower plate, and a bottom of the upper plate is fixed to the top of the locking guides.

Abstract: 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.

Abstract: Disclosed is a seat pumping device for a vehicle. The present invention provides a seat pumping device for a vehicle, the seat pumping device including: a clutch device which is rotated clockwise or counterclockwise by receiving external manipulation force, and has one or more manipulation flanges that are disposed at a predetermined interval in a circumferential direction and protrude in an axial direction; and a brake device which has one or more manipulation grooves in which the manipulation flanges are accommodated to come into contact with the manipulation grooves clockwise or counterclockwise so that the brake device is rotated clockwise or counterclockwise by receiving the external manipulation force from the clutch device, and performs a brake function such that the brake device is not rotated clockwise and counterclockwise by external force that is not through the clutch device.
