Since the stay rod pressing block 200 has a structure that is locked by a lock bar 300 after being in close contact with the stay rod at the bottom of the headrest (see B of FIG. 7) by sliding, the body 100 and the headrest can be firmly coupled.

Since the rigid coupling structure of the present invention stabilizes the body 100, it is very suitable for forming the movable cushion pad 400 variable from the body 100, and since the structure is stable, the variable position of the movable cushion pad 400 is further expanded can do it In addition, since the pressing force can be increased with the rotating bar 220 directly connecting the lock bar 300 and the stay rod pressing block 200, the coupling between the body 100 and the headrest can be firmly maintained even in an unstable state of the vehicle, If the vehicle is in a stable state, the connection of the rotation bar 220 may be released and the rotation bar 220 may be used as a support for mounting accessories.

The auxiliary headrest device 1 of the present invention is configured as follows. The auxiliary headrest device (1) is an auxiliary headrest device coupled to a vehicle headrest. ) Long groove 101 to be accommodated inside, a stay that is slidably coupled to the inside of the long groove 101 of the body 100 in a direction crossing the stay rod to press the stay rod to the first surface (refer to 201 in FIG. 3) The rod pressing block 200 is hinged to the body 100 to open and close the long groove 101, and a lock bar 300 for adhering and fixing the second surface of the stay rod pressing block 200 (see 202 in FIG. 3). , a pivot bar 220 hinged to the stay rod pressing block 200 to rotate to be caught on the lock bar 300 , and a movable cushion pad 400 rotatably installed on the body 100 .

In one embodiment of the present invention, the movable cushion pad 400 is coupled to the body 100 and connected to the distal end of the axially stretchable drive shaft 410 to be rotated around the drive shaft 410 (see FIG. 1 ). ), the rotating bar 220 is rotated upward around one end hinged to the stay rod pressing block 200, and the other end may be raised higher than the one end (see FIG. 3 ).

In addition, the rotating bar 220 includes a protrusion 221 for supporting the accessory at the other end, and the auxiliary headrest device 1 is drawn out from the body 100 in a sliding manner, and at a position lower than one end of the rotating bar 220 . The body 100 may include an accessory support bar (refer to 130 in FIG. 3) protruding to the outside together. With this structure, various functions can be provided to the rotating bar 220 to enhance user convenience.

Hereinafter, the configuration and effect of the present invention will be described in more detail based on one embodiment of the present invention.

Since the present invention is a structure coupled to a vehicle headrest, the vehicle headrest will be briefly described as follows. The headrest (refer to C in FIGS. 6 and 7) has a built-in cushion and is coupled to the top of the seat back (refer to D in FIGS. 6 and 7). The headrest is fixed by inserting a pair of stay rods protruding from the bottom (see B of FIGS. 6 and 7) into the seatback.

Each of the long groove 101, the stay rod pressing block 200, and the lock bar 300 of the present invention is formed in a number corresponding to the number of the stay rods in order to firmly support the stay rods. Since a typical stay rod is a pair, each of the long groove 101 , the stay rod pressing block 200 , and the lock bar 300 may be formed as a pair corresponding thereto. This embodiment is such an example, and therefore, a pair of long grooves 101 in the body 100, a pair of stay rod pressing blocks 200 corresponding to each long groove 101, each stay rod pressing It is preferable to understand that a pair of lock bars 300 corresponding to the block 200 are formed.

Referring to FIG. 1 , the body 100 may have a structure extending in the horizontal direction. The body 100 may be in the form of a block having a substantially long rectangular shape in the horizontal direction, but the cushion coupling part 110 for coupling with the movable cushion pad 400 protrudes from the front side, and the rear side is formed by the long groove 101 . It can be formed more three-dimensionally by being recessed (refer to the plan view of FIG. 3 ).

The front side of the body 100 may be disposed toward the front side of the seatback (the side on which a person is seated), and the rear side may be disposed opposite to the front side of the seatback. For example, when the present invention is coupled to the headrest of the passenger seat, the front side may face toward the backrest of the passenger seat back, and the rear side may face toward the rear seat.

The shape of the body 100 does not need to be limited to a block shape, and it extends long in the horizontal direction to form a long groove 101 on one side, and at both ends it is deformed to another shape advantageous for arranging the movable cushion pad 400 It is possible.

A movable cushion pad 400 is installed on the body 100 . The movable cushion pad 400 is disposed at both ends of the body 100 as shown in FIGS. 1 and 2 . The movable cushion pad 400 is connected to the driving shaft 410 by a connecting bar 420 , and the driving shaft 410 is rotatably coupled to the body 100 .

In particular, the driving shaft 410 is coupled to the body 100 in an axial direction so as to be stretchable or contracted as shown in FIG. 1 , and the movable cushion pad 400 is connected to the distal end of the driving shaft 410 to change the rotational position. have. That is, the movable cushion pad 400 itself is rotated around the driving shaft 410 , but the movable range of the movable cushion pad 400 is expanded because the driving shaft 410 itself increases or decreases in the axial direction.

Accordingly, the length of the drive shaft 410 may be adjusted in response to the width of the headrest, and the distance between the movable cushion pads 400 may be adjusted. When the movable cushion pad 400 is rotated around the driving shaft 410, the arrangement can be changed in various directions. A pair of movable cushion pads 400 may be symmetrically disposed at both ends of the body 100 as shown.

The movable cushion pad 400 has a built-in cushion therein, and the shape is not limited to a specific shape. As shown, in addition to the widely expanded shape, it can be freely deformed into other shapes. The pair of movable cushion pads 400 may have substantially the same movable range, movable structure and shape, and thus the rotational operation shown in FIG.

However, it is also possible to change the shape or movable structure of one of the movable cushion pads 400 to form an asymmetrical shape as needed. The cushion coupling portion 110 of the body 100 may include, for example, a hole (not shown) for accommodating the driving shaft 410 in an axial direction therein.

A long groove 101 is formed in the body 100 . The long groove 101 may be a long groove in the direction in which the body 100 extends. As shown in FIG. 3 , the long groove 101 is an indented groove indented from the outside to the inside of the body 100 , and thus the depressed portion is an open structure. The stay rod (refer to B of FIG. 7) of the lower end of the headrest is accommodated in the body 100 through the long groove 101.

The long groove 101 may be symmetrically formed on both sides of the center of the body 100 as shown in FIGS. 1 to 3 . The central portion of the body 100 in which the long groove 101 is not formed may protrude toward the rear side. The long groove 101 may include a sliding rail (refer to 1011 in FIGS. 2 and 3) formed in the longitudinal direction to accommodate the stay rod crossing the longitudinal direction.

The long groove 101 is opened and closed by a lock bar 300 to be described later, and is opened as shown in FIG. 3 when the lock bar 300 is opened, so that the stay rod can be accommodated very conveniently. The shape of the long groove 101 also does not need to be limited to the illustrated shape, and may be appropriately deformed to a size and shape for accommodating the stay rod to flow.

The stay rod pressing block 200 is slidably coupled to the inside of the long groove 101 of the body 100 in a direction crossing the stay rod, as shown in FIG. 3 . The sliding direction of the stay rod pressing block 200 is the same as the extending direction of the body 100 and the longitudinal direction of the long groove 101 . The stay rod pressing block 200 may move along the sliding rail 1011 inside the long groove 101 .

The stay rod pressing block 200 is fixed by being pressed by at least two different surfaces. The stay rod pressing block 200 presses the stay rod to the first surface 201 of the outer surface. Referring to FIG. 3 , the first surface 201 may be both surfaces positioned in the sliding direction of the stay rod pressing block 200 . The first surface 201 may be formed as a curved surface that can accommodate the stay rod. Preferably, the first surface 201 may be a concave curved surface.

A second surface 202 is formed on the other side of the stay rod pressing block 200 . The second surface 202 may be a plane extending in the sliding direction of the stay rod pressing block 200 , and may be a surface positioned in a direction toward the lock bar 300 among the outer surfaces. As shown in FIG. 3 , the second surface 202 may be formed to be relatively wide.

The stay rod pressing block 200 is formed in a three-dimensional shape in which the first surface 201, which is a concave curved surface, and the second surface 202, which is a relatively wide flat surface, are disposed on the outer surface. The stay rod pressing block 200 is sized to be movable inside the long groove 101 and the shape may be at least partially changed within the limit including the first surface 201 and the second surface 202 .

The lock bar 300 is hinged to the body 100 . The lock bar 300 rotates to open and close the long groove 101 , and to fix the second surface 202 of the stay rod pressing block 200 in close contact. That is, as shown in FIG. 3 , the long groove 101 can be opened and closed by rotating the lock bar 300 , and when the lock bar 300 closes the long groove 101 , it is in close contact with the stay rod pressing block 200 to stay It is possible to press and fix the rod pressing block 200 so that it does not move.

That is, when the lock bar 300 is closed, the long groove 101 is closed as shown in FIGS. 1 and 2 . On the other hand, when the lock bar 300 is opened, the long groove 101 is opened as shown in FIG. 3 . Therefore, the body 100 and the stay rod can be firmly coupled by accommodating the stay rod with the open long groove 101 and closing the lock bar 300 . The stay rod coupling process will be described later in more detail.

At the point where the stay rod pressing block 200 and the lock bar 300 come into close contact, a concave-convex coupling portion (see 210 and 330 in the enlarged view) as shown in FIG. 3 is formed. That is, the second surface 202 and the second surface 202 of the lock bar 300 are formed of a plurality of teeth 211 and 331 arranged to be engaged with each other on the contact surface 301 that is in close contact with each other. Concave-convex coupling portions 210 and 330 may be formed. The two are fixed without substantial movement by the concave-convex coupling portions 210 and 330 .

Referring to FIG. 3 , the concave-convex coupling portions 210 and 330 may be formed by gathering teeth 211 and 331 corresponding to each other. Since the stay rod pressing block 200 is slidably movable, the concave-convex coupling portions 210 and 330 may change their abutting positions according to the movement. However, when the lock bar 300 is closed at any position, the concave-convex coupling portions 210 and 330 mesh with each other and the movement of the stay rod pressing block 200 is prevented. With such a structure, it can be combined very firmly.

The lock bar 300 may have at least two different coupling parts. The lock bar 300 may form a double fixing point with coupling portions at different positions. The lock bar 300 is formed at the end of the lock bar 300 and protrudes from the outer surface of the first coupling part 310 and the lock bar 300 detachably from one side of the body 100 and extends in the longitudinal direction to both ends. It may include a bar-shaped second coupling part 320 in which the rotating bar 220 is hooked and fixed at a point therebetween.

As shown in FIG. 3 , the first coupling part 310 is formed at the end of the lock bar 300 . The opposite end of the first coupling part 310 is inserted into the body 100 and coupled to the body 100 by a hinge. The first coupling part 310 may be coupled to the lock bar fixing part 120 located outside the long groove 101 of the body 100 . The lock bar fixing part 120 may be formed by deforming a part of the body 100 and may include an elastic protrusion 121 and a lever 122 as a fixing structure.

The first coupling part 310 may be removably hooked and fixed to the elastic protrusion 121 . The elastic protrusion 121 may be supported by an elastic body and protrude out of the body 100 elastically. The elastic protrusion 121 is connected to the lever 122 so that when the lever 122 is pulled, it can be retracted into the body 100 .

A groove structure (not shown) caught on the elastic protrusion 121 may be formed inside the first coupling part 310 . In addition, a through hole 311 for exposing the lever 122 may also be formed on one side. The lock bar 300 can sufficiently maintain the coupling state to the body 100 only with the first coupling part 310 .

The second coupling part 320 is formed in a structure in which a rotation bar 220 to be described later can be caught on the outer surface of the lock bar 300 . The second coupling part 320 is formed in a bar shape extending in the longitudinal direction of the lock bar 300 . When the rotating bar 220 and the second coupling part 320 are coupled, the stay rod pressing block 200 and the lock bar 300 are directly connected to each other. Therefore, the adhesion strength of both sides is further increased. That is, as shown in the enlarged view of FIG. 2 , a more robust coupling structure can be formed by hooking and fixing the rotating bar 220 to the bar-shaped second coupling part 320 .

The rotating bar 220 is hinge-coupled to the stay rod pressing block 200 . Therefore, it can be rotated and moved as shown in FIG. 3 . Since a fixing hook 222 protrudes from the rotating bar 220 , it may be rotated and caught on the lock bar 300 . Specifically, the fixing hook 222 is coupled to the above-described second coupling part 320 and may be caught at any point among the second coupling parts 320 extending in a bar shape.

Therefore, it is possible to move the stay rod pressing block 200 to an appropriate position in the long groove 101 and close the lock bar 300 to closely and fix the second surface 202 of the stay rod pressing block 200, again By closing the rotation bar 220, the lock bar 300 can be double fixed (refer to FIGS. 1 and 2).

However, it is not necessary to maintain such a fixed state, and since the lock bar 300 can maintain the combined state only with the first coupling part 310 , if the vehicle is stable, the rotating bar 220 can be moved from the lock bar 300 . It can be separated and used as a movable support by adjusting the direction of rotation.

To this end, the pivot bar 220 is rotated upward around one end hinged to the stay rod pressing block 200, and the other end may be raised higher than the one end (see FIG. 3 ). That is, the rotating bar 220 may rotate upward and be inclinedly disposed upwards of the body 100 (see FIG. 6 ). Using this structure, it can also function as an effective support. A protrusion 221 for supporting an accessory may be formed at the other end of the pivot bar 220 to contact the supported object as shown.

The accessory support protrusion 221 protrudes from the other end of the pivot bar 220 , and the protruding length may be increased or decreased as necessary. Therefore, there is no need to be limited in the form of drawings. One end opposite the protrusion is coupled to the stay rod pressing block 200 by a hinge and functions as a rotation center. By using the friction of the hinge, it is possible to control the rising angle of the rotation bar 220 to a desired angle.

If such a rotating bar 220 is used appropriately for the situation, it is possible to increase the bonding strength of the device, or it is possible for a passenger in the rear seat to view the screen while holding a smartphone or tablet PC. A specific method will be described later and again.

In addition to the rotating bar 220, the present invention includes other structures that can increase user convenience. Hereinafter, this will be described in more detail.

On one side of the body 100 , as shown in FIG. 3 , a bar 130 for supporting accessories that is drawn out from the body 100 in a sliding manner is formed. The accessory support bar 130 protrudes to the outside of the body 100 at a position lower than one end (ie, the hinged end) of the pivot bar 220 . Therefore, it is possible to support the supported object together with the pivot bar 220 at different positions. The accessory support bar 130 may include an upwardly refracted locking protrusion 131 at its distal end.

The accessory support bar 130 does not restrict the space because it can be used by withdrawing from the body 100 when necessary. The accessory support bar 130 may be protruded to an appropriate length to be used as a hanger for holding belongings such as a bag, or it may be used as a holder for holding a smartphone or tablet PC together with the rotating bar 220 . The locking protrusion 131 may support the lower part of the hanging item or the mounted smart phone or tablet PC to prevent it from being separated to the outside.

In addition, the lock bar 300 includes a perfume accommodating space 332 formed inside the lock bar 300 , and a door 331 for opening and closing the outer surface of the lock bar 300 so that the perfume accommodating space 332 can be accessed. can be formed. Therefore, as shown in Figure 2, the door 331 can be opened and the fragrance (A) is inserted therein and the fragrance can be discharged to the surroundings. The door 331 may have a ventilation hole 331a capable of discharging the fragrance.

The above-described movable cushion pad 400 is disposed toward the front side of the body 100 to increase the convenience of the seated passenger, and such a user-friendly structure is disposed on the rear side of the body 100 for the convenience of the passenger seated in the rear seat. can be greatly improved. Specific usage examples will be described later in more detail.

4 and 5 are plan views sequentially illustrating the coupling operation of the auxiliary headrest device of FIG. 1 .

Hereinafter, the coupling method of the auxiliary headrest device 1 and its effect will be described in more detail with reference to FIGS. 4 and 5 . Due to the above-described structural features, the auxiliary headrest device 1 of the present invention is coupled to the headrest as follows.

First, as shown in FIG. 4, the stay rod (B) is accommodated in the long groove 101, and the stay rod pressing block 200 is adjusted to be in close contact. Since the long groove 101 can be opened by opening the lock bar 400 , the stay rod B outside the body 100 can be easily introduced into the body 100 .

Since the stay rod pressing block 200 is slidably moved inside the long groove 101, it is possible to closely adhere to the stay rod (B) without being constrained by the position or spacing thereof. By moving the stay rod pressing block 200, it is possible to combine the concave first surface 201 in a form surrounding the stay rod (B).

As shown, since the first surface 201 is formed on both sides of the stay rod pressing block 200, if the interval of the stay rod B is wide or the position is different, the first surface 201 suitable therefor can be used It is also possible to press the stay rod (B) to the first surface 201 in front of the moving direction by moving the stay rod pressing block 200 in the opposite direction to the direction shown.

In order to alleviate the impact of the contact portion between the stay rod (B) and the device, an elastic body (B1) made of rubber or the like may be inserted between the stay rod (B) and the first surface 201 .

After adjusting the position of the stay rod pressing block 200 in this way, as shown in FIG. 5 , the lock bar 300 is closed to fix the stay rod pressing block 200 . Since the lock bar 300 is hinge-coupled to the body 100, the lock bar 300 can be rotated to close the long groove 101, and at the same time, the stay rod pressing block 200 can be closely adhered and fixed.

In particular, when the lock bar 300 is closed, the above-described second surface 202 and the concave-convex coupling portions 210 and 330 formed in pairs on the contact surface 301 of the lock bar 300 come into close contact with each other and engage with each other, so the stay rod The pressing block 200 is fixed substantially without movement. The stay rod pressing block 200 is very firmly fixed while exchanging pressure between the second surface 202 in close contact with the lock bar 300 and the first surface 201 in close contact with the stay rod (B).

After the lock bar 300 is coupled in this way, a double coupling structure may be formed on the lock bar 300 by rotating the rotation bar 220 . When the rotating bar 220 is engaged, the bonding strength of the lock bar 300 is further increased.

Since the lock bar 300 is in close contact with the body 100 through the first coupling part 310 and is double coupled with the rotating bar 220 through the bar-shaped second coupling part 320, the stay rod pressing block (200) is also closer. As a result, the pressure applied to the point where the lock bar 300 and the body 100 are in close contact and the pressure applied to the point where the lock bar 300 and the stay rod pressing block 200 are in close contact (indicated at the corresponding point in FIG. 4 ) back arrow) to form a very strong bonding structure.

Since it is firmly coupled in this way, all operations such as expansion and contraction or rotation of the drive shaft 410 formed in the auxiliary headrest device 1, and withdrawal of the accessory support bar 130 are very stable. In addition, depending on the situation, since the pivot bar 220 can be used for other purposes by being inclined upward, convenience is increased in various ways. Hereinafter, a use case of the present invention will be described in more detail with reference to FIGS. 6 and 7 .

FIG. 6 is a side view illustrating one use state of the auxiliary headrest device of FIG. 1 , and FIG. 7 is a perspective view illustrating another use state of the auxiliary headrest device of FIG. 1 .

When the auxiliary headrest device 1 is coupled to the headrest C through the above-described process, the state is as shown in FIGS. 6 and 7 . The stay rod (B) of the headrest (C) may be exposed long as shown depending on the situation, and may be further inserted into the seatback (D) to reduce the exposed portion.

In this way, the auxiliary headrest device 1 is coupled, and various accessories can be mounted on the auxiliary headrest device 1 as shown in FIG. 6 . For example, the accessory E2 such as a smartphone or a tablet PC may be mounted in an inclined state so that the screen can be viewed. For example, the rotation bar 220 is rotated upward to set an elevation angle, and the accessory support bar 130 can be protruded to mount the accessory E2 between the two at an angle.

As a result, passengers in the back seat can view the screen of a smartphone or tablet PC more conveniently. If the length of the accessory support protrusion 221 is appropriately increased or decreased, the smartphone or tablet PC may be further erected, so the length of the accessory support protrusion 221 and the angle of the rotation bar 220 are changed to change the angle of inclination or mounting of the supported object. The state can be adjusted more appropriately.
