This article relates to the folding device of the head restraint of a chair of a passenger car. In particular, the head restraint of the driver's seat is folded forward or backward so that the head restraint is folded when there are no seats in the side seat. Or, the purpose of the driver is to allow the driver to drive safely and to use the inside space of the car in a wide and comfortable way.

Conventionally, the head restraint is erected and fixed on an empty seat next to the driver's seat. When driving alone, the head restraint of the side is installed. There are times when people sitting in the back seats are uncomfortable using the interior spaces, such as obscuring the view of the front, so that the present invention solves such discomforts, and at the same time, the head restraint is used only when no one is in the seat next to the driver. If you do not have a chair or need to be folded at ease so that you can use the convenient and wide view of the driver's field of view.

On the upper part of the chair 1, the fixing plate 3 having the hinge tube 4 formed on one side is fixed to the front bottom of the head support 2, which is usually used as the head support 2, and the hinge tube 4 The coupling tube 8 having the key groove 6 formed in the head 7 inside the coupling tube 8 and the coil spring 10 protruding from the key 9 '. The key tube 9 receives the elasticity of the coil spring 10 by tightening and screwing the screw tube 11 into the screw portion 8 'of one end of the coupling tube 8 and binding body 8 to the binding tube 8 ) And the threaded pipe (11) in the center portion of the insertion hole (12) to form a length respectively, the upper end portion (13a) (13'a) of the support leg (13) (13 ') by inserting the binding pipe (8) and Thread hole 15 'formed on the surface of the screw hole 15 of the outer head 7, 7' and the upper end 13a, 13'a of the support leg 13, 13 '. To the hinged pipes with screws 16 and the support legs 13 and 13 'in accordance with the width adjustment. The screw hole 16 'is screwed into and fixed to the screw hole 17 of the screw hole 17 and the key pipe 9 of the key hole 9 so that the key pipe 9 matches the hinge pipe 4 in a fixed state. The support legs 13 and 13 'are fixedly mounted by being inserted into the fixing groove 19 as shown in FIG. And in the supporting leg (13) (13 ') to form a plurality of locking grooves 20 to be securely supported.

The present invention constituted as described above has a plurality of threaded holes 15 'formed in the plane of the support legs 13, 13', and upper ends 13a, 13'a as screw holes for width adjustment. In accordance with the screw holes 15 formed in the heads 7 and 7 'of the tubular body 11, the support legs 13 and 13' are adjusted to the width required by assembling from the outside as the screws 16 and the chair ( 1) can be installed in the fixing groove 19, so that there is a convenient effect that can be installed at that time and is securely supported by a plurality of locking grooves 20 formed on the support legs 13, 13 ' In the key tube 9 fixed to the hinge tube 4 with a screw 16 ', the key' 9 'of the key tube 9' is formed in the head 7 of the binding tube 8, and the key groove 6 When the head restraint 2 is folded and folded in the state of being inserted into the key, the key 9 'is rotated in accordance with the rotation of the head restraint 2 while exiting from the key groove 6, as shown in FIG. section On the contrary, if the headrest 2 is raised upward as shown by the dotted line of FIG. 5, the key 9 'of the key tube 9 is inserted into the key groove 6 so as to be erected. .

In addition, since the key 9 'of the key pipe 9 and the key groove 6 of the head 7 are formed of ar, the folding action is well facilitated by the pivoting operation of the headrest 2 for easy insertion and removal. Pipe body (9) is subjected to the elastic action of the coil spring 10, so the headrest (2) is securely erected by its elasticity can be used conveniently.

Therefore, the folding of the headrest (2) can not only help the driver to widen the field of view safe driving, but also has the advantage of using a wide and comfortable space in the car.
