Description

POWER RECLINER DEVICE {DEVICE RECLINER FOR VEHICLE}

The present invention relates to a power recliner device, wherein reclining is smoothly performed by a wedge spring when the lever socket is operated in a no-load state, and when the lever socket is operated in a loaded state, And the rotational force of the lever socket is transmitted to the power reclining apparatus in which the seat back vibration and the trembling phenomenon do not occur during the reclining operation.

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.

1, a conventional power recliner includes a first gear 2 coupled with a seat back (not shown) and having an internal gear 2a formed therein, and a second gear 3 The first gear 2 and the second gear 3 are structurally different in gear size (gear teeth number) and different pitch circle diameters (PCD: pitch circle diameter) The second gear 3 is eccentrically coupled to the first gear 2 so that the eccentric state is maintained by a pair of wedges 4 and 5 interposed in the interspace and a locking state or a reclining action The unlocking state is maintained.

However, in the above conventional recliner, the second gear 3 is supported only by the pair of wedges 4, 5 from the burring portion 2b of the first gear 2, The wedges 4 and 5 are brought into contact with the ring portion 2b in a one-point contact so that the burring portion 2b and the wedges 4 and 5 There is a problem that noise is generated due to metal friction.

Further, when the wedges 4 and 5 are brought close to each other by the rotation of the socket 1, the conventional recliner is provided between the one side wedge primarily moved by the socket and the second gear 3, A gap is generated between the wedge 3b and the wedge 1, and then the wedge is repeatedly released. As a result, there is a problem in that the seatback is jolted and moved (trembling) and the passenger is not comfortable.

Particularly, in the conventional recliner, due to the assembly tolerance or clearance between the components, it is possible to prevent a change in the recliner operation of the seat back provided with various machines and electronic devices (load operation - recliner operation under load or force applied to the seat back) The vibration of the seat back due to the variation of the center of gravity of the seat back depending on the angle of the seat back is generated. As a result, the comfort of the seat can not be secured.

In the conventional recliner, since the rotation force of the socket is transmitted by one point contact between the parts, it is difficult to transmit the correct rotational force between the parts, and the operation force of the socket must have a certain force or more. A certain amount of capacity has to be secured, which causes many problems in designing a small compact sheet.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lever socket which is capable of restricting operation by a small operation force when the lever socket is contacted by two or more points of the lever socket, And does not generate vibration and vibration due to a clearance between the parts at the time of power reclining.

The present invention relates to a power reclining apparatus in which an external gear coupled to an internal gear is eccentrically rotated by rotation of a first and second wedge and a cam in accordance with driving of a lever socket to adjust an angle of a seatback, When the lever socket is rotated, the lever socket, the first and second wedges and the cam are brought into contact with each other by two or more points to transmit the rotational force of the lever socket without vibration and vibration.

Since the rotation of the lever socket is transmitted by the engagement between the parts which are contacted by the lever of two or more points and the external gear is eccentrically rotated, when the load of the seatback, in which various mechanical devices and electronic devices are installed, Even when the center of gravity is changed, the assembling tolerance between the parts and the vibration, the noise and the noise due to the clearance are not generated, and the recliner is operated naturally.

In the present invention, the lever socket, the first and second wedges and the cam are brought into contact with each other by at least two points so as to be interlocked, so that the rotational force is easily transmitted by the operation force of the small lever socket.

Since the external gear is eccentrically rotated in a state where the lever socket is in contact with the first and second wedges and the cam at least two points, there is no occurrence of operating loss, .

The distance AL5 between the first and second actuating projections 11 and 12 of the lever socket to the cam protrusion 24 of the cam is set so as to correspond to the sum of the distance AL1 or AL2 and the distance AL3, The first and second wedges 50 and 60, the cam 20, and the lever socket 10 remain coupled.

At this time, the distance AL1, AL2, AL3, AL4, AL5 means the angle with respect to the center point O of the bearing 43.

- Recliner operation (no load)

8, when the lever socket 10 is rotated in the A direction in the above-described locked state, the first operating projection 11 of the lever socket is engaged with one end 53 of the first wedge 50, The first operating surface 14 of the lever socket wedge operating groove is brought into contact with the outer surface 55 of the first wedge first projection so that the operating torque of the lever socket is applied to one side of the first wedge 50 8 (a) shows the engagement relationship between the first and second wedges at the start of the no-load operation, FIG. 8 (b) shows the engagement relationship between the first and second wedges at the start of the no- , And a coupling relation between the two wedges and the lever socket wedge operating grooves.

9, when the lever socket 10 is rotated in the A direction, the first wedge 50 is rotated in the A direction by the lever socket 10, The second operating projection 12 of the lever socket is brought into contact with the cam projection 24 of the cam at the same time that the lever socket 10 is in contact with the pressing surface 27 of the first wedge inserting groove 21, Is simultaneously transmitted to the pressing surface 27 and the cam protrusion 24 in the first wedge insertion groove 21 of the cam (cam operation start). Fig. 9 (a) (B) shows a coupling relation between the first and second wedges and the lever socket wedge operation groove.

- Recliner operation (load condition)

Further, when a load or a force is applied to the seat back and the operation of the recliner is not smoothly performed by the self-elastic force of the wedge spring (in a load state), when the lever socket 10 is continuously rotated in the A direction The contact surface 54 of the first wedge contacts the contact surface 64 of the second wedge and at the same time the pressing surface 28 in the second wedge insertion groove of the cam engages with the second projection of the second wedge, The operation torque of the lever socket is simultaneously transmitted to the contact surface 64 of the second wedge and the second projection 62 (load operation start-reclining automatic). Fig. 10 (a) (B) shows a coupling relationship between the first and second wedges and the lever socket wedge operating groove.

The first operating surface 14 of the lever socket and the outer surface 55 of the first wedge, the first operating projection 11 of the lever socket and one end 53 of the first wedge, The second projection 52 of the first wedge and the pressing surface 27 of the first wedge insertion groove and the second operation projection 12 of the lever socket and the cam protrusion 24 are kept in contact with each other, And the wedge spring 70 between the first and second wedges repeats the compression / relaxation (elastic) operation.

Further, when the lever socket 10 is rotated in the B direction, the second wedge is rotated by the lever socket, the cam is rotated by the second wedge and the lever socket, and the second wedge and the cam cause the first wedge And is rotated in the rotating direction of the lever socket.

As described above, according to the present invention, the lever socket, the first and second wedges and the cam are separated from each other by two points at the start of the load operation, in which vibrations and vibrations are generated at each time when the center of gravity is changed due to clearance between components, So that the rotational force is stably generated.
