Abstract
Description
The present invention relates to a seat recliner for minimizing the number of components and clearance by applying an insert injection to prevent internal inflow of a coating liquid and preventing the inflow of a coating liquid in a double manner.
The present invention is a device equipped with a hinge for connecting a cushion to a bag and a function for adjusting the backrest back and forth by being mounted on an automobile seat. The device has convenient control function for adjusting the optimum driving posture, maintenance function after adjustment, To a recliner for an automobile seat, which is an important function product of a vehicle seat that requires strength that can be applied to a vehicle seat.
In recent years, there have been a lot of products that are coated with recliner, which is a seat core component, due to increased corrosion resistance of automotive parts and concerns about appearance exposure. However, there has been a phenomenon in which the operation part is not smoothly operated due to the injection of the coating liquid. Particularly, in the case of the connecting rod inserting part, that is, the inside part,
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
The present invention has been proposed in order to solve such a problem, and it is an object of the present invention to provide a seat recliner which minimizes the number of components and clearance by applying insert injection to prevent internal inflow of a coating liquid, .
In order to attain the above object, a recliner of a seat according to the present invention is characterized in that a first shaft through hole is formed at the center, a plurality of guide portions are protruded and formed on an inner side surface, and a first sealing bush Lowered lower plate; A second shaft through hole is formed on the lower plate so as to be rotatable and is coupled to the shaft at the center. A second shaft bushing is coupled to the second shaft through hole, and a lower end of the second shaft bushing is connected to the upper ; A plurality of lock gears disposed between the guide portions of the lower plate and slid by the cam; And an inner tooth that is rotatably mounted on the lower plate and is engaged with the lock gear, a third shaft through hole is formed at the center, a third shaft bushing is coupled to the third shaft through hole, And an upper plate in contact with an upper end of the two-sealing bush.
A first flange protruding upward can be formed on the outer circumference of the upper surface of the first sealing bush, and the upper end of the first flange can contact the lower surface of the second sealing bush.
A second lower flange protruding downward may be formed on the inner circumference of the lower end surface of the second sealing bush and a lower end of the second lower flange may contact the upper surface of the first sealing bush.
A second lower flange protruding downward is formed on the inner circumference of the lower end surface of the second sealing bush and a lower end of the second lower flange contacts the upper surface of the first sealing bush while the second lower flange and the first flange are spaced apart from each other.
A second upper flange protruding upward can be formed on the inner circumference of the upper surface of the second sealing bush and an upper end of the second upper flange can be brought into contact with the lower surface of the third sealing bush.
A third flange protruding downward may be formed on the outer circumference of the lower end surface of the third sealing bush and a lower end of the third flange may be in contact with the upper surface of the second sealing bush.
A third flange protruding downward is formed on the outer periphery of the lower end surface of the third sealing bush, a lower end of the third flange contacts the upper surface of the second sealing bush, and the third flange and the second upper flange are spaced apart from each other.
The recliner of the present invention includes a ring-shaped sealing cover which surrounds an outer end of an upper plate; And a retainer which encloses the sealing cover and the upper plate together and is fastened to the lower plate.
A plurality of support ribs projecting outwardly are formed apart from the outer end of the lower plate, and a plurality of fitting pieces sandwiched between the support ribs may be formed at the outer end of the retainer.
The outer end of the sealing cover may be formed with an outwardly projecting extension spaced apart and the extension may be positioned between the point of interposition of the lower end of the retainer and the upper end of the support rib.
According to the recliner of the seat of the present invention, insert injection is applied to prevent the internal inflow of the coating liquid, thereby minimizing the number of components and clearance, and preventing the inflow of the coating liquid into two.
It has the effect of increasing the merchantability through the addition of one component and the application of coating liquid inflow prevention structure and improves the productivity problem by improving the stability of the operating part in the case of coating the existing recliner.

FIG. 1 is an exploded perspective view of a recliner of a seat according to an embodiment of the present invention, FIG. 2 is a view showing an assembled state of a recliner of a seat according to an embodiment of the present invention, Sectional view taken along the AA line.
The present invention comprises a cam (200), a lower plate (100), an upper plate (600), and a sealing cover (700). In the case of the inner part of the recliner, each component is injection-molded after camming, and the inside of the shaft insertion part is formed once more to prevent the injection of the coating liquid in the first place, and after the lower / upper plate processing, insert injection is performed It is a double barrier structure that prevents the inflow of coating liquid once again by molding twice. The outside of the recliner is a structure that prevents the inflow of the coating liquid between the retainer and the lower plate by applying the outer sealing cover.
