Folding recliner of seat for vehicles

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. 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.

Description

technical field [0001] The present invention relates generally to a folding recliner for a vehicle seat, and more particularly to a folding recliner for a vehicle seat that enables seat folding and reclining motion using only a single lever, Thereby reducing the size of the link mechanism and the number of components, and reducing its manufacturing cost, and wherein a latch pin (latchpin) and a brake link are provided in the arm frame, so that the folding and tilting movement of the seat can be performed independently, And prevent malfunctions in folding or reclining seats. Background technique [0002] As known to those skilled in the art, a vehicle seat includes a seat cushion to support the weight of an occupant, and a seat back to support the occupant's back. [0003] Generally, the seat back is rotatably mounted on the seat cushion through a hinge, and the angle of the seat back relative to the seat cushion can be adjusted according to the occupant's intended purpose. ...

AI Technical Summary

Problems solved by technology

[0015] However, in the above structure in which the lock pin 62 moves under its weight, there is a problem that the lock pin 62 may not move smoothly due to friction between the groove and the lock pin 62

Also, the locking pin 62 may not be unlocked so that the folding motion of the seat back cannot be performed.

[0016] Furthermore, in the conventional folding recliner, since the seat back reclining control lever 31 and the seat back folding control lever 71 are provided on the same side of the seat frame, there is a possibility of failure in the folding or reclining of the seat back. Problems such as the user may mis-operate the reclining lever 31 when it is desired to fold the seat back or the user may mis-operate the folding lever 71 when it is desired to perform a reclining movement of the seat back

[0017] Furthermore, since the reclining control lever 31 and the folding control lever 71 are provided on the same side of the seat frame, the linkage mechanism operated by these levers is complicated and increases the size of the folding recliner

In addition, there is also the problem of increased manufacturing costs and labor costs
