Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for assembling an armrest,

The present invention relates to an assembling structure of an armrest, and more particularly, to an armrest assembling apparatus for a vehicle that restricts lateral movement of the armrest to prevent the armrest from being detached from the seatback.

2. Description of the Related Art Generally, two heat-transfer sheets for seating a driver and a front passenger are installed on all seats of a vehicle, and a heat-transfer sheet on which a plurality of passengers can sit together is installed on a back seat.

In the center of the rear seat, an armrest for stably placing an arm of an occupant is provided.

1 shows a conventional armrest. The armrest 101 is rotatably mounted to the center of the seatback 105 from a central portion of the seat cushion 104 by a hinge bracket 107. As shown in FIG. That is, when the armrest is not used, the armrest is housed in the receiving groove 106 formed at the center of the seatback 105. When the armrest is used, the armrest is drawn out from the receiving groove 106 of the seatback 105 So that the arm rest is used.

The hinge pin 108 is easily inserted into the hinge bracket 107 to rotate the armrest. When the armrest is moved to the left and right, the hinge pin is easily separated from the hinge bracket, There is a problem that the armrest can be easily detached from the seatback.

On the other hand, "rear armrest locking device" of Korean Patent Laid-Open Publication No. 10-2001-0061864 has been conventionally introduced.

However, such a method fixes the position of the armrest in the withdrawn state of the armrest, which can not fundamentally solve the problem of separating the armrest by the left and right swinging of the armrest in the process of storing and withdrawing the armrest.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an armrest assembling apparatus for a vehicle which prevents the armrest from being detached from the seatback by restricting lateral movement of the armrest.

According to an aspect of the present invention, there is provided an arm rest including a receiving portion formed on a front surface of a seat back, the armrest being retracted and drawn out in accordance with rotational movement and having a hinge pin at a side end thereof; A hinge bracket installed at an inner end of the accommodating portion and having a hinge hole formed at an end thereof so that the hinge pin is rotatably fitted; And detachment preventing means provided at an end of the hinge pin so as to be larger than an inner diameter of the hinge hole so that the end of the hinge pin is caught by the hinge bracket on the inner surface side of the hinge hole to prevent the hinge pin from being separated from the hinge pin. .

The release preventing means may be formed by protruding a stopper on the outer peripheral surface of the end portion of the hinge pin.

The inner circumferential surface of the hinge hole may have a releasing groove having a shape corresponding to the size of the stopper in the radial direction of the hinge hole.

A guide pin is provided at a side end portion of the armrest adjacent to the hinge pin; And a guide hole is formed at a predetermined radius of rotation around the hinge hole so that the guide pin is inserted into the guide hole and guided.

According to the present invention, since the stopper is formed at the end of the hinge pin, the stopper is caught by the inner surface of the hinge bracket, so that the hinge pin is prevented from being separated from the hinge bracket. There is an effect of preventing separation from the seat back.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing an installation state of an armrest according to the prior art; Fig.
Fig. 2 is a view showing a shape in which an armrest according to the present invention is assembled to a hinge bracket and a shape of a stopper. Fig.
3 is a view for explaining an arrangement relationship of stoppers according to the rotation position of the armrests according to the present invention and a structure capable of preventing and separating the armrests.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a view showing the shape of the armrest according to the present invention assembled to the hinge bracket and the shape of the stopper, Fig. 3 is a view showing the arrangement relationship of the stoppers according to the rotation position of the armrest, And Fig.

The armrest assembling apparatus for a vehicle of the present invention mainly comprises an armrest (30), a hinge bracket (20) and an escape preventing means.

2 and 3, the present invention will be described in detail. In the housing 12 formed on the front surface of the seatback 10, a hinge pin 32 is provided at a side end portion thereof, An armrest 30; A hinge bracket 20 installed at an inner end of the accommodating portion 12 and having a hinge hole 22 formed at an end thereof so that the hinge pin 32 is rotatably fitted; And the end of the hinge pin 32 is larger than the inner diameter of the hinge hole 22 so that the end of the hinge pin 32 is caught by the hinge bracket 20 on the inner surface side of the hinge hole 22 And detachment preventing means configured to prevent disengagement of the hinge pin (32).

The end of the hinge pin 32 inserted into the hinge hole 22 is formed to be larger than the inner diameter of the hinge hole 22 so that the armrest 30 moves in the left and right direction away from the hinge bracket 20 The end of the hinge pin 32 is caught by the inner surface of the hinge bracket 20 so that the hinge pin 32 is prevented from being separated from the hinge bracket 20, It is prevented that the armrest 30 is separated from the seatback 10 during use of the seat back 10.

Referring to FIGS. 2 and 3, in the present invention, the release preventing means may be formed by protruding a stopper 32a on the outer peripheral surface of the end portion of the hinge pin 32. FIG.

Here, a plurality of the stoppers 32a may be formed on the outer circumferential surface of the hinge pin 32.

That is, when the armrest 30 is accommodated in the accommodating portion 12 and is rotated in a state of being drawn out from the accommodating portion 12, the hinge pin 32 is rotated in the hinge hole 22 At this time, the stopper 32a is rotated with the hinge bracket 20 interlocked, so that the armrest 30 is not separated from the hinge bracket 20.

3, the inner circumferential surface of the hinge hole 22 may be formed with a release groove 22a having a shape corresponding to the size of the stopper 32a in the radial direction of the hinge hole 22 have.

That is, in a state in which the armrest 30 is completely received in the receiving portion 12 formed in the seatback 10, or completely rotated and drawn from the receiving portion 12 toward the seat cushion side, the stopper 32a The armrest 30 is prevented from being separated from the hinge bracket 20 by the hinge bracket 20. However, when the armrest 30 is rotated at a predetermined rotational displacement from the receiving portion 12, The stopper 32a is aligned with the release groove 22a. Therefore, when maintenance and replacement of the armrest 30 are required, the armrest 30 can be detached from the seatback 10 and replaced.

At this time, it is preferable that the release groove 22a is formed in a shape corresponding to the size of the stopper 32a, but the size of the release groove 22a is larger than the size of the stopper 32a 32a.

Referring to FIG. 3, in the present invention, a guide pin 34 is provided at a side end portion of the armrest 30 adjacent to the hinge pin 32; A guide hole 24 is formed at a predetermined radius of rotation around the hinge hole 22 so that the guide pin 34 is inserted into the guide hole 24 and guided.

The guide pin 34 is guided along the guide hole 24 when the armrest 30 is accommodated and drawn out so that the armrest 30 can be stably rotated, The movement of the guide pin 34 is restricted when the guide pin 34 is positioned at both ends of the guide hole 24. In particular, when the armrest 30 is pulled out, So that it is prevented from moving up and down.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It is natural.
