Abstract

PURPOSE: A rear arm rest locking device prevents vibration and noise of an arm rest in driving a vehicle. CONSTITUTION: A rear arm rest locking device comprises a pin hole(11), a locking pin(13), a locking spring(15) and a locking groove(17). When an arm rest rotates to be received in a receiving groove, the locking pin(13) engaged with the pin hole(11) is inserted and connected with a hinge bracket(7) by elastic force of the spring(15), which hinders the arm rest from being rotated or moved without receiving force more than connecting force between the locking pin(13) and the locking groove(17). Also when an arm rest rotates to be out from the receiving groove or is positioned on a seat cushion, the operation of the locking pin(13) is the same with the above.

Description

Locking arm of rear arm rest

The present invention relates to an armrest of a rear seat of a vehicle, and more particularly, by allowing the armrest rotating about the hinge to be locked to a use position and a non-use position, the armrest may have a sense of theft according to the rotation of the armrest. Of course, it relates to the armrest locking device to prevent the vibration of the armrest and thus the noise during driving.

In general, the interior of the vehicle is provided with two front seats that can be seated by the driver and the front occupant, the rear is provided with a rear seat that can be seated simultaneously by a number of rear passengers.

In addition, each armrest is provided in the console box and the front door between the two front seats to comfortably lift each occupant's arm. The armrests are also provided in the center of the rear seat and inside the rear door. .

1 shows a conventional rear armrest 101, which is rotatably mounted from the center of the seat cushion 104 toward the center of the seatback 105 by a hinge bracket 107. As shown in FIG. .

Therefore, the armrest 101 is stored in the receiving groove 106 formed at the center of the seatback 105 when not in use, that is, when three people ride on the rear seat 103 or want to secure the wide seat cushion 104. In use, the seatback 105 is rotated forward from the receiving groove 106 of the seat back 105 and positioned in the center of the seat cushion 104, so that a person on the rear seat 103 can put his arm thereon.

However, the conventional rear seat armrest 101 as described above does not have a structure and a device capable of locking and fixing the use position and the non-use position, so there is no sense of theft during rotation, and vibration according to the shaking of the vehicle body during driving. There is a problem that occurs and noise.

Therefore, the present invention has been made in view of the above problems, it is possible to lock the armrest rotating around the hinge in the use position and non-use position to have a sense of theft according to the rotation of the armrest. Of course, it is an object of the present invention to provide an armrest locking device that can prevent the vibration of the armrest and the resulting noise during the driving of the vehicle.

In order to achieve the above object, the present invention provides a device for locking and fixing an armrest rotatably mounted to a hinge bolt through a hinge bracket on a seat cushion center portion of a rear seat, the hinge bolt and A pinhole concaved in the same lateral direction, a locking pin installed to be movable in the longitudinal direction in the pinhole, a locking spring for urging the locking pin toward an inner surface of the hinge bracket, and a recess formed in the bracket so that the armrest It provides a rear armrest locking device including two locking grooves that are engaged with the locking pin while moved to the use position or the non-use position.

In addition, the outer end of the locking pin in contact with the hinge bracket is formed in a curved surface, the locking groove is preferably formed in the inclined surfaces facing each other along the rotation radius of the hinge bolt.

Hereinafter, an embodiment of the present invention will be described in more detail based on the accompanying drawings.

Figure 2 shows a rear seat armrest 1 is provided with a locking device 10 according to an embodiment of the present invention, Figures 3 and 4 are rear armrest locking device 10 according to an embodiment of the present invention. Will be shown.

As shown, the rear armrest locking device 10 is pivotally mounted to the hinge bolt 8 by the hinge bracket 7 at the center of the seat cushion 4 of the rear seat 3. ), The pinhole 11 is recessed in the same lateral direction as the hinge bolt 8 on both side surfaces of the armrest 1 adjacent to the hinge bolt 8, and the pinhole 11 is locked. The pin 13 is installed to be movable in the longitudinal direction, the locking hole 15 for pressing the locking pin 13 toward the inner side of the hinge bracket 7 is elastically installed in the pin hole 11, the hinge The bracket 7 is formed with two locking grooves 17 engaged with the locking pin 13 in the state in which the armrest 1 is rotated to the use position or the non-use position.

In addition, the outer end of the locking pin 13 is smoothly contacted with the hinge bracket 7 and is formed in a curved surface so that the unlocking of the armrest 1, that is, the detachment from the locking groove 17 is relatively easy.

Then, the locking groove 17 is coupled to the locking pin 13 that moves in this way when the armrest 1 is located in the seat cushion 4 or the receiving groove 6 in the center of the seat back 5. It is formed in the rotation radius of the locking pin 13 around the hinge bolt (8), the inclined surface 18 is formed to face each other along the rotation radius of the hinge bolt (8).

According to the rear armrest locking device 10 according to the embodiment of the present invention configured as described above is as follows.

First, when three people ride on the rear seat 3 or want to secure a wide seat cushion 4, the rear armrest 1 pivots upward with respect to the hinge bolt 8 of the hinge bracket 7. It is accommodated in the accommodation groove 6 formed in the center of (5). At this time, the locking pin 13 fitted into the pinhole 11 of the armrest 1 is inserted into and coupled to the locking groove 17 of the hinge bracket 7 by the elastic force of the spring 15 to lock the armrest 1. Until the force greater than the coupling force between the locking pin 13 and the locking groove 17 according to the spring 15 is transmitted, the armrest 1 is restrained from rotating or moving relative to the hinge bracket 7.

On the other hand, when the armrest 1 is applied to the armrest 1 in a forward direction to rotate the armrest 1 from the non-use position to the center portion of the seat cushion 4 which is the use position, the locking pin 13 is a locking groove. The spring 15 is compressed while moving inwardly of the pinhole 11 along the inclined surface 18 of the 17, and at the same time, the lock groove 17 is released.

At this time, the armrest 1 is free to rotate. If the armrest 1 is positioned in the seat cushion 4 by continuously rotating forward in this state, the locking pin 13 is inserted into the locking groove 17 of the hinge bracket 7 as in the non-use position described above. As it is coupled to the armrest (1) is to lock.

In addition, in the process of rotating the armrest (1) to the use position or emergency position, the locking pin 13 is elastically coupled to the locking groove 17 of the hinge bracket (7) to theft of the armrest (1) rotation. I can feel it.

As described above, the present invention is able to lock the armrest to the use position or non-use position to have a sense of theft according to the rotation of the armrest, and also to prevent the vibration of the armrest and the noise caused by driving You can do it.

While the invention has been shown and described with respect to particular embodiments, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the appended claims. Anyone can easily know.
