Description

Headrest tilting structure of the driver's seat

The present invention is manufactured separately from the driver's seat back at the upper part of the driver's seat back, and connected to the driver's seat back, so that the driver tilts the neck backward to rest and rests at the head rest of the driver's seat (SEAT HEAD REST) (S). In the past, the headrest of a passenger car driver's seat equipped with a headrest is provided for the above purpose, but since the tilting device structure is complicated, there is a lot of manufacturing labor and accordingly, a manufacturing cost is increased. In order to solve the same problem, the utility model registration application No. 98-15156 filed under the name of "headrest tilting structure of the driver's seat of the passenger car", the scope of the claim for registration of rights of the first application No. 98-15156 of the applicant

"In constructing a tilting device for tilting the HEAD REST installed in the driver's seat,

Planar hinge 53 is coupled to the inner surface of the one side wall 50 of the "c" wall (50) (50a) planarly (53), the other end of the ratchet (51) length of the tooth (51a) Slightly longer to form the inclined end 52 of the upper end of the tooth (51a) and protruding the protrusion 52 (52a) on both sides of the end of the ratchet (51), but the protrusion 52 protruding toward the wall 50 is the wall 50 The upper and lower motions are allowed to penetrate through the guide hole 54 installed vertically in the up and down), and the compression coil spring is formed between the stiffener 52a and the rear side wall 50b in the ridge 52a protruding on the opposite side of the wall 50 side. 55 interposed therebetween, a plurality of ratchet teeth 51b are formed in a circumferential shape in the upper middle portion at the lower side of the ratchet 51, and a protruding portion 56 is formed by protruding the tip portion on the outer surface of the ratchet teeth 51b. The ratchet which is configured to be inclined to the indentation corner of the inclined end 51c formed at the upper end of the ratchet 51 by forming the bending protrusion 57a by bending the upper end thereof. The support protrusion 60 protrudes from the center portion 57 of the fish, and the protrusion 60 is inserted into the guide hole 59 installed in the “c” -type wall surface 50 so as to be freely moved, and the fixed support interval 58. The coil spring 61 is wound on the outer circumferential surface of the fixed support section 58 located inside the "c" -shaped wall 50 (50a), but one end of the spring 61 is recessed in the midway portion of the retreat gear 57. The device is configured to allow the tank 62 to be fixed and fixed, and the other end of the spring 61 is installed with a fixing hole 63 in the upper middle part of the wall 50a to be inserted and bent into the fixing hole 63. "SEAT HEAD REST" tilting structure of the driver's seat.

By the way, the electoral draft of the party applicant with the above-described structure is the one end of the "a" type ratchet 51 of a certain length is rotatably constructed by the hinge 53 and the other end is interposed between the left and right (52) Bulge 52a is accommodated inside the guide hole 54 installed on the top of the "c" -type wall 50 on one side of the "c" -type inclined operating opening (R) is a "b" type ratchet (51) to move up and down to a constant height and the other side (52a) of the other end of the "a" type ratchet (51) in the direction that the compression coil spring 55 always compresses the "a" type ratchet (51) It has a structure that the force acts so that the hinge portion of the "a" type ratchet (51) wears and loosens as the use time elapses, and the "a" type ratchet (51) by the holding force of the coil spring (55). The toothing device 51a and the toothing toothe 51b formed in the ratchet gear 57 are not spaced apart from each other and the tilting structure cannot be used as a tilting device. This problem occurred in reliability.

The present invention is an improved design that minimizes the failure by solving the problems shown in the application No. 98-15156, which is the first draft of the applicant, and simplifying the structure as described above. In the "c" type inclined actuator R having a width, a fixed support 12 extending through the lower end of the "c" type wall 1 or 1a is inserted and the inner surface of the "c" type wall 1 is inserted. The ratchet gear 11 which is constructed integrally with the fixed support interval 12 is spoken, and a plurality of ratchet teeth 7 are cut in the upper periphery of the ratchet gear 11, and the end of the ratchet gear 11 is a bending protrusion 5. ) And the other end of the ratchet gear 11 forms a rising edge 11a that is significantly higher than the height of the ratchet teeth 7a and is in contact with the ratchet teeth 7. This downwardly protruding " a " actuating tool 9 is provided with a hinge &lt; RTI ID = 0.0 &gt; 8 &lt; / RTI &gt; The guide worker installed on the "c" wall by rotating the support protrusion (2) on the edge of the tip of the "a" type operation hole (9) and rotating it on the "c" wall of the Donggu (R). The upper end edge of the "a" type operating tool (9) and the upper end edge of the lower end 9a so that the angle thereof is significantly smaller than 90 °, and is treated with the end 9a. It is possible to install the leaf spring (10) having an elastic force to always hold the "b" type operating port (9). Unexplained parts of the drawings are the same as the contents of the original application of the applicant, so the description is omitted.

Referring to the operation state of the present application configured as described above as shown in Figure 1 attached to the fixed support 12 is fixed to the back of the driver's seat back (C) and the "c" type inclined operating mechanism (R) is It is installed inside the head restraint (S), but the initial state before the tilting is as shown in Figure 4a of the toothbrush (7a) of the "b" type operating tool (9) is a toothbrush of the ratchet gear (11) The bent projection 5 at the tip of the reclining gear 11 protruding section 6 is inclined to the inclined end 13 formed at the tip of the “a” type operating port 9 and is in contact with the tip protruding section 6 of 7). The support protrusion 2a of the "a" type operation tool 9 is interposed at the lower end of the guide hole 3 installed in the "c" type wall 1 of the "c" type inclined operation tool R, Position and the leaf spring 10 is supported on the end 9a of the "a" type operating tool 9, and tilted while tilting the head restraint S to the rear side at a necessary angle. 12) and fixed The ratchet teeth 7 abutted on the front bent portion of the “b” type operation tool 9 at the ratchet teeth 7 formed on the upper surface of the ratchet gear 11, which is arranged in contact with the ratchet teeth 7 at an inclined angle. When tilting the head restraint (S) as far as possible when the driver wants to return the head restraint (S) while maintaining the tilted state at an appropriate inclination, the "c" type tilt actuator (R) is as shown in FIG. 4C. Of the "a" operating tool which is tilted rearward with respect to the fixed support section 12, and which is rotatably constructed with a hinge 8 on the "c" shaped wall 1 of the "c" type tilting actuator (R). While the upper end surface of the inner toothed tooth (7a) and the rising edge (11a) formed inside the upper surface of the ratchet gear (11), the hinge (8) is pushed upwards on the lower end of the "a" type operation tool (9). Ascends to the upper end of the guide hole (3) installed in the a "type actuator (9), and the other end (9a) of the" a "type actuator (9) is the bent head of the leaf spring (10). The frost 10a is moved downward while being burnt. In this way, when the "t" type inclined actuator (R) is repositioned while the ratchet teeth (7) and the tooth (7a) are spaced apart, the "a" type actuator (9) and the tooth (7) and the tooth (7a) are spaced apart. To the original position, the end surface of the ratchet teeth (7a) of the "a" type operating tool (9) is hinged to the bending protrusion (5) formed on the upper end of the ratchet gear (11) while the hinge (8) is positioned downward Moving and at this time, the edge of the leaf spring 10 is momentarily retracted to the upper side while the original position in the state of Fig. 4a to the tilting operation in the present application because the tilting operation is made as a significantly simpler structure than in the original draft of the applicant.

As described above, the headrest tilting structure of the driver's seat can be provided at a low manufacturing cost even though the structure is simpler and has no trouble.
