Abstract: A latch assembly for vehicle seat comprising a base having a receiving pocket accommodating a striker of a vehicle body part, a catch rotatably coupled to the base rotating between a locking position where the catch supports the striker and an unlocking position where the catch allows the striker to escape, a damping plate rotatably coupled to the base with the same rotating axis as the catch elastically pressing catch to rotate to the unlocking position and having a damping surface elastically pressing and supporting the striker, a pawl plate rotatably coupled to base having a pressing surface pressing the catch rotated to the locking position, a pawl rotatably coupled to base having the same rotating axis as the pawl plate and having a supporting surface supporting catch preventing further rotation if the catch at locking position rotates passing the pressing surface of pawl plate due to an outer impact.

Abstract: A seat moving track assembly comprising a stationary rail having at a lower part of one side thereof recesses and having at an upper part of the other side thereof openings, a moving rail having first side holes to correspond to the recesses and second side holes to correspond to the openings, a locking member having first stopping protrusions projecting through the first side holes coupled into the recesses and second stopping protrusions projecting through second side holes coupled into the openings, an elastic connecting member having a shaft supporting part to rotatably support the locking member, an elastic pressing part to rotate the locking member, and unlocking means for rotating the locking member in the other direction to release a coupling between the first stopping protrusions and the recesses and a coupling between the second stopping protrusion and the openings, thereby providing stability and a simplified configuration.

Abstract: The present invention improves the shape of a protruding part of a locking member which allows a lower stationary rail and an upper moving rail of a seat moving track assembly to be coupled with each other, thereby enabling a stable movement with a further simplified configuration component.

Abstract: A torsion beam axle includes a torsion beam, a plurality of trailing arms made of a material different from that of the torsion beam, and connecting tubes made of a material better than that of the trailing arms with respect to weldability with the torsion beam, and integrally coupled to the trailing arms at one end part thereof, and welded to the torsion beam at the other end part thereof. Thereby, the coupling force between the trailing arms and the torsion beam made of different materials can be improved.

Abstract: Disclosed herein is a seat recliner for vehicles. The seat recliner of the present invention includes a support bracket, which is mounted to a seat frame, a guide holder, which is coupled at a first end thereof to the support bracket, and a slide holder, which is rotatably coupled to the guide holder between the support bracket and the guide holder. The seat recliner further includes at least one rotating bracket, which is coupled to the slide holder, a clutch unit, which controls the engagement between the guide holder and slide holder, and a control unit, which controls the clutch unit. The slide holder has a stop unit, which protrudes towards the support bracket, and the support bracket has a stopper, which contacts the stop unit when the slide holder is rotated at a predetermined angle, thus limiting rotation of the slide holder within a predetermined range.

Abstract: A pumping device and a height adjuster for a vehicle seat are disclosed. The pumping device comprises a support plate; a cam receiver accommodated in the support plate; a brake cam received in the cam receiver to be integrally rotated with the shaft, and defining receiving spaces between the brake cam and the cam receiver; locking means received in each receiving space to allow and prevent rotation of the brake cam in the cam receiver; a control plate for applying the pushing force to the locking means; a bidirectional clutch coupled to the control plate if rotating force is applied and returned to a state of being decoupled from the control plate if the rotating force is not applied; a cover plate assembled with the support plate; a lever plate provided outside the cover plate; and elastic returning means for returning the lever plate to a predetermined reference position.

Abstract: Disclosed herein is a folding recliner of a seat for vehicles which is able to execute both seat folding and reclining motions using only a single lever. The folding recliner of the present invention includes a lever unit, which has a lever pin and a lever, so that, when the lever is rotated in a predetermined direction, the lever unit is rotated around a reclining shaft so that the seat back enters an unlocked state. The folding recliner further includes a first link, which has a contact part on a lower end thereof, and a second link, which is rotated around a rotating shaft, coupled to the second link, by movement of the first link. The folding recliner further includes a spring, which is coupled between the second link and a frame unit, and a cam, which is rotated around the rotating shaft and has a locking protrusion.

Abstract: A high-rigidity recliner according to the present invention comprises an upper actuating member attached to a seat base, and a lower actuating member attached to a seat back and is characterized by the upper actuating member supporting a pair of symmetrical lock gears fixedly interposed between a cam and a lower actuating member. Outer gear parts of the lock gears engage inner gear parts of the lower actuating member, whereby any clearances between the outer gear parts and inner gear parts are eliminated and any irreular engagement of the outer and inner gear parts is prevented. The lock gears lock or release the lower actuating member by rotation of the actuating cam. The simple structure of the present invention reduces the number of parts, the time for assembly, and the cost of manufacturing. Additionally, forming the outer and inner gears by blanking improves strength and durability of the recliner.
