The present invention is an improved application for the present applicant's application for solving the problems of the application No. 98-25832, which he previously filed, as described above, based on the accompanying drawings. It is provided with a 'c' type inclined operating port (R) to be built inside the head restraint (S) that is speeched through the fixed support interval (12) to tilt the head restraint (S), but the 'c' The fixed support section 2 penetrates substantially the lower midway portion of both side walls 1 and 1a of the type inclined actuator, and is integrally constructed with the fixed support section 2 on the inner side of one side wall 1 and has a plurality of upper surfaces. The ratchet teeth 3 are formed in an arc shape, and one side end surface of the ratchet teeth 3 forming surface is formed with a rising edge 4 with a constant inclination and height upward, and the other end of the ratchet teeth 3 is a protruding part ( 5) is protruded to a constant height upward and within the projections 5 The surface is made into an arcuate surface 5a, and the tip of the protruding section 5 is fixed to the reinforcing gear 7 provided with the bent projection 6, which is bent in the direction in which the retreating teeth 3 are formed. And a support protrusion 8 protruding from the lower edge of the rising edge 4 formed on the upper surface of the ratchet gear 7 so as to penetrate through the long groove 9 cut laterally in the middle portion of the one side wall 1. And the lower side of the retreat gear 7 and the lower side of the protrusion between the protrusions 5 is formed so as to be formed of the corner portion 10 having a constant angle and is formed with such a ratchet gear (7) Equipped with a 'b' type operation port 11 but the upper side edge (11a) of the 'a' type operation tool 11 a corner at a predetermined angle and one side wall (1) with a hinge 12 in the middle part The other side of the 'b' type operating port 11 is bent downwardly to a certain length and rotated to the hinge. Teeth (3a) is formed and the upper jaw (13) protruding on the top surface and the tip edge (11a) and the reclining gear (7) provided to have a predetermined angle at the upper end of the 'b' type operation port 11 configured as described above 'B'-type leaf springs 14, which allow the edges 10 of each of them to be tangled, are fixed to the inner wall of the' c'-type inclined actuator R as fixing fixtures 15, but fixed on the upper side of the leaf springs 14, respectively. By bending the spring corner 14a bent at an angle, the structure of the 'c' type inclination operating mechanism R in the present application is constructed.

The operation state of the present application configured as described above will be described with reference to the drawings of FIGS. 3 and 4. First, the partially cutaway perspective view of FIG. 3 and FIG. 4A show the headrest S tilting to an initial state. This state is shown before this state is the ratchet teeth (3a) of the 'b' type operation tool (11) between the ratchet teeth (3) of the upper surface of the ratchet gear (7) and the reclining gears (7) protrusion (5) ) Is in contact with the bent projection (7) of the bent projection (7) is hanging on the hanging jaw (13) of the 'b' type operating port 11, the upper end (11a) of the 'b' type operating port (11) ) And the edge portion 10 of the ratchet gear 7 is in a state where the ends of the 'b' type leaf springs 14 are supported.

In addition, the upper end (11a) of the 'b' type operating port 11 is located in the upper side of the edge 14a of the leaf spring 14 bent at a predetermined angle. In this state, when the 'c' type inclined operating port (R) is pushed backward, the fixed support section (2) and the reclining gear (7) fixed to the fixed support section (2) are 'c' type without moving. The inclined actuator (R) is tilted while tilting the fixed support section (2) to the rear. At this time, the long groove (9) installed in the middle part of the side wall (1) of the 'c' type inclined actuator (R) is also a reitered gear. (7) is supported by the support protrusion (8) protruding inclined in a stable state and the ratchet teeth (3a) of the 'b'-type operating port 11 is a ratchet teeth (3) formed on the upper surface of the ratchet gear (7) When moving backward and stopping the rear tilting operation of the head restraint (S) at a proper inclination in that state, the ratchet teeth (3) and (3a) is in contact with each other, so the tilting state is maintained. Now, when the tilted head restraint (S) is to be returned to its original position, the tilted head restraint (S) is further tilted to the rear. As shown in FIG. (11a) is inclined in the leaf spring (14) inclined state as the end surface of the inner tooth of the ratchet teeth (3a) of the 'b'-type operating port 11 is raised to the rising edge (4) of the ratchet gear (7) The left toothed tooth 3a is spaced apart from the left toothed toothed tooth 3 formed in the toothed gear 7, and at the same time, the upper leading edge 11a of the rear of the 'a' type actuating tool 11 is gradually lowered. It is inclined to the apex of the spring edge 14a of the spring 14, and is momentarily out of the corner 14a of the spring, and is momentarily repositioned below the corner 14a bent above the leaf spring 14. The ratchet teeth (3a) of the a 'type operation tool (11) and the ratchet teeth (3) of the ratchet gear (7) are spaced apart It is maintained. In this state, the lower side of the leaf spring 14 is pushed by the edge portion 10 of the ratchet gear 7 so that the force of holding the edge portion 10 is doubled and the edge portion 10 is supported by the edge portion 10. .

When the head restraint (S) is released while the 'ㄷ' type tilt operation tool (R) is tilted to the maximum, the restoring force of the leaf spring 14 holding the edge portion 10 of the ratchet gear 7 is reduced. (7) The holding force for pressing the corner portion 10 acts, but this holding force is fixed to the holding support (2) and the ratchet gear (7) is fixed to the end of the fixed support (2) as the axis type Since it acts as a rotation restoring force to rotate the inclined operating port (R) is the 'c'-type operating port (R) is to the original position. In this way, the tip of the ratchet teeth (3a) of the 'b' type operating port 11 is inclined downward while being treated with the protrusions 5 of the ratchet gear 7 as shown in FIG. The upper end 11a of the 'shaped actuating tool 11 is instantaneously deviated from the edge 14a of the leaf spring 14 and is positioned above the edge 14a of the leaf spring 14. Gripping force pushes the upper end (11a) of the 'a' type operation tool (11) upward with the hinge (12) as the axis, and at the same time the end of the ratchet teeth (3a) of the 'a' type operation tool (11) Since the inner circular arc surface (5a) of the publication (5) is moved to the lower side in the end, the 'b'-type operating port 11 is changed to the original position of the initial 4a degree while changing the position downward to the axis of the hinge (12) do.

As described above, the 'A' type operation tool 11 and the ratchet gear 7 are supported by only one leaf spring 14, thereby simplifying the structure and further bending the upper edge of the leaf spring 14 14a) is an extremely simple structure and reliable and trouble-free headrest tilting by displacing the position of the 'b' type actuating member 11 by the upper tip edge 11a formed at the rear of the 'a' type actuating member 11a. A structure can be provided.
