Description

A rear seat head rest in vehicle}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headrest of a vehicle seat, and more particularly to a headrest of a rear seat of a vehicle in which passengers in the rear seat of the vehicle can arbitrarily adjust the position and height of the headrest according to their physical conditions.

In general, a vehicle seat is provided with a headrest for supporting the occupant's head for comfortable riding of the occupant at the upper end of the backrest. Although the seat is somewhat different depending on the model of the vehicle, it is usually manufactured in a constant size. However, since the passengers in the vehicle have different physiques, the relative height of the headrest relative to the head varies according to the passengers in the vehicle, making it difficult to optimally support the head of the passenger.

In addition, most of the models currently produced are exported overseas. In the case of domestic cars, seats produced according to the body of the Koreans are fitted, but in the case of export cars, there is a problem that it is difficult to produce seats that fit the body of the locals due to the price of the vehicle.

The front seat of the vehicle is designed to allow passengers to adjust according to the seating status, so it is less inconvenient, but the rear seat of the vehicle is designed to prevent the occupant from adjusting the seating status. Since the head restraint does not fit the occupant's body, it is seated in an inconvenient posture. Therefore, since the seat of the vehicle is the convenience mechanism of the vehicle which the driver or the passenger first encounters, it is necessary to increase the comfort of the occupant.

The present invention was devised to solve the above problems, the head of the rear seat of the vehicle so that the occupant of the vehicle can be comfortably installed by adjusting the height and position of the head rest constituting the rear seat of the vehicle to the passengers arbitrarily The purpose is to provide a rest.

1 is a perspective view showing an embodiment of a head restraint of a vehicle seat according to the present invention. In the head rest provided on a rear seat seat of a vehicle, the head rest is vertically installed below the head rest 10. The height adjustment rod 20 to adjust the height of the 10, it is installed horizontally in the lower portion of the height adjustment rod 20 is composed of a horizontal moving rod 30 to allow the head rest 10 to move left and right It is shown.

In addition, in order to facilitate the left and right movement of the horizontal movement rod 30, the guider 40 formed to have a semi-circular cross section is installed in a portion in contact with the lower portion of the horizontal movement rod 30, the pinion at the end of the rotation shaft The rack gear 50 meshing with the pinion gear 50 moves the horizontal moving rod 30 formed on the side by using the motor M installed with the gear 60.

As shown in the figure, a space is preferably formed inside the rear seat so that the horizontal moving rod 30 can move left and right.

An embodiment of the present invention configured as described above will be described with reference to the drawings.

When the occupant in the rear seat of the vehicle adjusts the headrest according to his physical condition, the occupant may manually move the headrest 10 to the left and right, but when the headrest 10 is moved by using a motor. Convenience becomes high.

FIG. 2 is a perspective view showing a coupling state between a horizontal moving rod and a motor used in the present invention, and FIG. 3 is a sectional view of the A-A line of FIG. 2 showing the configuration of the height adjusting rod used in the present invention.

As shown in the figure, since it is necessary to move the head rest 10 to the right or left side according to the physical condition of the occupant, the occupant sets the rotation direction of the motor M by using the operation switch SW. And rotate the motor (M).

When the motor M rotates, the pinion gear 60 installed at the end of the rotation shaft of the motor M rotates, and the rack gear 50 moves by the rotation of the pinion gear 60. Since the rack gear 50 is formed on the side of the horizontal movement rod 30, the horizontal movement rod 30 moves left and right by the movement of the rack gear 50. At this time, the horizontal movement rod 30 is smoothly moved by the guider (40).

When the head rest 10 is moved to an appropriate position, the occupant stops the operation of the operation switch SW so that the head rest 10 stops the left and right position setting.

After the left and right positions of the head rest 10 are set, the occupant sets the height of the head rest 10 in accordance with the head height of the occupant.

4 is a view showing the configuration of the height adjustment rod used in the present invention, Figure 5 is a detailed view of the portion A of Figure 4, the height adjustment rod 20 is provided inside the head rest 10. It is shown. Fixing grooves 24 are formed on the side surfaces of the height adjustment rods 20 at predetermined intervals, and end portions of the fixing rods 26 having a linear rod shape are inserted into the fixing grooves 24 so that the headrests 10 are fixed. Formed. At this time, since the fixing device 26 may be separated by vibration generated during driving of the vehicle, the height adjustment state of the head rest 10 may be changed, and the spring 28 may be installed around the fixing device 26 so that The fixed state is maintained by the applied elastic force.

In order to fit the head rest 10 in which the positions of the left and right sides are set to the height of the occupant's head, the fastener 26 inserted into the fixing groove 24 of the height adjustment rod 20 is separated. Since the headrest 10 is freely movable up and down in the state in which the fixture 26 is disengaged, the occupant adjusts the height of the head rest 10 with his head height, and the fixture 26 in a state where the height is correct. ) Is inserted into the fixing groove 24 so that the height of the head rest 10 is fixed.

When the left and right positions and heights of the headrest 10 are set in accordance with the physical condition of the occupant as described above, a person in the rear seat of the vehicle may feel comfortable while driving the vehicle.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to these embodiments, and has been claimed by those of ordinary skill in the art to which the invention pertains. It includes all the various forms of embodiments that can be carried out without departing from the spirit.

As described above, according to the present invention, it is possible to adjust the left and right positions and heights of the headrests installed in the rear seat of the vehicle according to the physical condition of the occupant, so that even if the person seated in the rear seat of the vehicle is a large foreigner, Since it can obtain, it is effective to improve the merchandise of a vehicle, without changing a seat according to the export destination country of a vehicle.
