Abstract

According to the present invention, an auxiliary headrest can be used without changing the structure of a seat assembly by facilitating the attachment to and detachment from a headrest (20) joined to a seat (10), and is capable of responding to a distance between height adjustment bars installed in various models of vehicles as a through-hole (42) is extended in the longitudinal direction of a frame (40).

Description

Assistance headrest

The present invention relates to an auxiliary headrest, and more particularly to an auxiliary headrest detachably coupled to a seat of a vehicle to support a head side of a user.

Generally, a headrest is provided on the upper side of a seat back which forms a seat, and the headrest is installed in a structure that can be moved up and down on the seat to support the head of the occupant.

Here, the headrest prevents the head of the occupant from being turned back when the vehicle is suddenly stopped while driving or colliding with another vehicle, thereby preventing the occupant from being injured.

In addition, the conventional headrest supports the head of the occupant while driving to help relax or sleep in a comfortable posture.

However, since the conventional headrest is disposed behind the head of the occupant, the side portion of the occupant can not be supported.

In addition, the conventional headrest has a problem that the head of the child can not be supported because the height of the headrest is small when the occupant is a child.

FIG. 1 is a perspective view of an auxiliary headrest according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is a structural view of FIG. 1, and FIG.

The auxiliary headrest according to the present embodiment is detachably coupled to the headrest 20 coupled to the upper side of the seat 10 of the vehicle through the height adjusting bar 22, A cushion 50 installed at both ends of the frame 40 to support the head of the occupant by being rotated forward and backward with respect to the frame 40, And a joining unit 60 for joining the frame 40 and the height-adjusting bar 22 together.

The seat 10 and the headrest 20 have the same structure as that of a conventional vehicle, and the auxiliary headrest according to the present embodiment is configured to be detachably attached to a seat assembly of a conventional structure for personal convenience.

The frame 40 is tightly fixed to the height adjusting bar 22 by the engaging unit 60 and the through hole 42 is formed in the inner side so that the engaging unit 60 can be inserted therethrough. .

It is preferable that the length of the through holes 42 is formed to be long enough to include all the intervals of the height adjusting bars 22 provided on the general-purpose vehicle, because the intervals between the height adjusting bars 22 are different depending on the vehicle Do.

Therefore, the frame 40 includes a frame body 41 closely attached to the height adjusting bar 22, a through hole 42 extending elongated in the longitudinal direction of the frame body 41, And a cushion engaging portion 44 formed at both side ends of the cushion 50 to which the cushion 50 is coupled.

The cushion 50 and the cushion engaging portion 44 are formed in the shape of a groove in this embodiment and one end of the cushion 50 is inserted and engaged with the cushion 50, 44 may be coupled by hooks.

The cushion 50 includes a cushion fixing portion 52 coupled to the cushion coupling portion 44 and a cushion portion 54 hinged to the cushion fixing portion 52 and rotated in the front- And a hinge portion 56 for connecting the cushion portion 54 and the cushion fixing portion 52 so as to rotate relative to each other.

The hinge portion 56 includes a rotation button 57 for interrupting rotation of the cushion fixing portion 52 and the cushion portion 54 and an elastic member (not shown) for supporting the rotation button 57 .

When the user does not press the rotary button 57, the cushion fixing portion 52 and the cushion portion 54 are kept locked and not rotated. Only when the rotary button 57 is pressed, The portion 52 and the cushion portion 54 can be relatively rotated.

The elastic member is disposed inside and resiliently supports the rotary button 57. When the operation force by the user is removed, the rotary button 57 is returned to the original position so that the cushion fixing portion 52 and the cushion portion 54 are locked State.

The coupling unit 60 is for fixing the frame 40 to the height adjusting bar 22 and one side of the height adjusting bar 22 is hooked to the height adjusting bar 22 through the through hole 42 And a tightening portion 64 which is coupled to the frame 40 and is in contact with the thread of the engaging member 62.

One side of the latching member 62 is formed in a hook shape, and the other side is formed with a male screw thread 63 on the outer circumferential surface.

At the center of the axis of the throttle portion 64, a female thread (not shown) is formed which is engaged with the male thread 63 of the engaging member 62.

Therefore, after the hook of the hooking member 62 is hooked on the height adjusting bar 22 and the other side is inserted into the through hole 42 of the frame 40, And the tightening member 64 is fastened to the male screw member 63.

When the tightening member 64 is rotated and the tightening member 64 is brought into close contact with the frame 40, the frame 40 is firmly fixed to the height adjusting bar 22 by the engaging unit 60 .

Since the coupling unit 60 can be moved in the left and right direction along the through hole 42, the coupling unit 60 can easily correspond to the gap of the height adjusting bar 22. [

In addition, since the auxiliary headrest 40 can be easily attached and detached in a state where the headrest 20 is coupled to the seat 10, there is an effect that the auxiliary headrest 40 can be used without changing the structure of the seat assembly.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
