Pumping device and height adjuster for vehicle seat

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. In the structure of the seat recliner disclosed in the present invention, the recliner prevents malfunctions of a seat back and makes the process of manufacturing the seat recliner more efficient.

Seat recliner for vehicles

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. The folding recliner further includes a latch which is rotated around a folding shaft and has a curved edge part, so that the curved edge part contacts an upper end of the cam so that the seat back maintains an unfolded locked state thereof, and a locking notch formed at a predetermined position in the outer edge of the latch so that the locking protrusion of the cam is locked to the locking notch so that the seat back maintains a folded locked state thereof.
