Description

RECINER OF VEHICLE SEET BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a seat recliner for an automobile, in which a lever socket is axially and tightly coupled to a second gear member by a self-resilient restoring force of the elastic contact ring, so that the lever socket, the first gear member, The retaining property and the fluidity of the first and second gear members are improved and the penetration of the coating liquid through the gap between the lever socket and the first gear member is prevented.

BACKGROUND OF THE INVENTION [0002] Generally, a recliner is capable of adjusting an angle of a seat back in a front-rear direction with respect to a seat cushion. The recliner is provided with a strong coupling force between components during a reclining operation, Manual type that adjusts the angle and power type that automatically operates by the power of the motor through switch operation.

Such a recliner is engaged with the second gear member eccentrically engaged with the first gear member, and a friction rotation member made of a wedge, a cam, or a cam, a wedge, or the like is inserted and installed between the first gear member and the second gear member A lever socket for rotationally moving the friction rotary member is connected to the first gear member so that the friction rotary member is rotationally moved by the rotational force of the lever socket and the second gear member is rotated by the rotational movement of the friction rotary member, So that the recliner is operated by being eccentrically rotated in the first gear member.

However, in the conventional recliner, after the hub formed at the center of the lever socket is inserted into the first gear member, the fixing ring is fixed to the end of the hub penetrated through the first gear member by welding or simple fitting A gap is generated between the lever socket and the stationary ring, between the stationary ring and the first gear member, and the lever socket is caused to flow in the axial direction due to the occurrence of such clearance.

Particularly, when a clearance is maintained between the lever socket and the first gear member, axial flow is generated in the second gear member located between the lever socket and the first gear member to lower the engagement force between the first and second gear members As a result, not only the rotational force of the lever socket can be transmitted quickly, but also the reclining actuation force may be lowered.

In addition, when a gap is generated between the lever socket and the first gear member, operational noise due to a clearance between the parts is generated, and during the coating operation of the recliner in the subsequent process, There is a problem that the penetration of the coating liquid adversely affects the recliner where fine and precise operation is performed.

The lever socket 10, the second gear member 40 and the first gear member 30 are assembled together with the lever socket 10 and the first gear member 30, leaving only the minimum tolerance that does not affect the operation of the frictional rotary member. The member 30 and the elastic contact ring 50 are tightly engaged without any clearance so that the axial flow of the lever socket is prevented.

That is, the elastic contact ring 50 has the end 55 of the resilient supporting portion 54 as a supporting point, which is a contact point between the peripheral engaging jaw 53 and the peripheral groove 16, The force is applied to the lever socket 10 in the C direction as a whole by the elastic contact ring 50 thus engaged with the one side face 37 of the first gear member, So that the lever socket 10 is tightly coupled with the first gear member 30 in the axial direction without generating a gap.

When the lever socket 10 is pressed and tightly coupled to the first gear member 30 by the self-elastic restoring force of the elastic contact ring 50, that is, the resilient restoring force of the elastic supporting portion 54, The fixing plate 11 of the socket 10 presses the bearing 43 integrated with the second gear member 40 in the direction of the first gear member 30 so as to press the inner gear 32 of the first gear member 30, The space between the fixing plate 11 of the lever socket 10 and the receiving groove 33 of the first gear member is engaged with the friction rotary member 20, The frictional rotary member 20 rotates in a limited axial flow between the receiving groove 33 and the lever socket 10 in a limited axial gap space to a limited axial flow The operation quality of the recliner is improved.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
