Description

Tilt structure of car headrest

The present invention relates to an automobile seat, and more particularly, to a tilt structure of an automobile headrest that is configured to be able to rotate the headrest of the seat within a certain angle range to increase the convenience.

In general, the floor of the vehicle is provided with a front seat and a rear seat for the driver and passenger to sit. Usually, the front seat of a vehicle employs a separate type in which a driver's seat and a passenger's seat are separately, while the rear seat adopts a bench type in which left and right seats are integrally combined.

1 shows a conventional vehicle front seat. As shown, the overall configuration of the front seat is a fixed angle with the seat cushion 3 and the horizontal frame 2 fixed on the horizontal frame 2 moving back and forth along the guide rail 1 installed on the floor. It consists of a seat back (5) fixed to a vertical frame (4) arranged with a. In addition, the upper part of the seat back (5) is equipped with a headrest (7) that can protect the head of the passenger in the event of a rear collision, and can rest while leaning against the head, both sides of the seat back The side guard (6) for the waist protection is formed. In addition, the length adjustment lever 8 is installed to adjust the position of the seat according to the body of the occupant, and the angle adjustment lever 9 that can adjust the inclination angle of the seat back 5, which is the backrest portion on the side of the seat It is installed.

The conventional headrest for a vehicle having such a configuration can be adjusted to fit the height of the occupant because it is mounted in the seat back while moving vertically, but the angle is always fixed, so it is inconvenient depending on the occupant. It has a problem that causes it.

The present invention devised in view of the above problems by adjusting the installation angle of the headrest to fit the body of the occupant, to provide a tilt structure of the headrest for the vehicle for increased comfort by allowing the head to lean in a comfortable posture. There is this.

An object of the present invention described above is a seat cushion mounted on the floor so as to move along a guide rail fixed to the floor, and the seat back seat is installed in the seat cushion to be rotatable at an angle, the seat is stored in the seat back It is possible to mount the guide rod having a pinhole and guide groove, a stopper sliding along the guide groove, and both side walls are rotatably mounted to the guide rod by fixing pins, and a plurality of stops to which the stopper is fitted Consists of a bracket having a jaw, the bracket is achieved by the tilt structure of the headrest for the vehicle, characterized in that it comprises a locking release means for releasing the engagement state of the stopper and the locking jaw.

According to the present invention, by adjusting the height of the headrest according to the height of the occupant, and then tilt the head by appropriately adjusting the angle by rotating the headrest, it provides an advantage to increase the convenience.

Hereinafter, the tilt structure of the headrest for a vehicle according to the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing a tilt structure of the headrest according to the present invention, Figure 3 is an exploded perspective view showing a tilt structure of the headrest according to the present invention, Figure 4 is a side view showing an operating state of the headrest according to the present invention. to be.

First, as shown in the assembled state in Figure 2, looking at the tilt structure of the headrest according to the present invention, the guide rods 20, 26 and the fixing pin 30 that is mounted to be receivable in the seat back By being rotatably mounted to the guide rods 20 and 26, the headrest 10 shown by the virtual line is comprised by the bracket 40 which can adjust a position within the range of a fixed angle.

In addition, a plurality of locking jaws 44 are formed on both sidewalls of the bracket 40 to maintain the pivoting state of the headrest 10, and the guide grooves 24 are formed on the guide rods 20, 26. Formed. As in the conventional structure, a plurality of grooves 28 are formed on the inner surfaces of the guide rods 20 and 26, so that the headrest 10 can be moved vertically in steps from the receiving portion of the seat back.

In addition, the stopper 32 is formed on both sidewalls of the bracket 40 as a locking release means for releasing the coupling state between the stopper 32 and the locking jaw 44, including the locking jaw 44. The inclined portion 44c which rises along the upper side, and the pressing end 44a and the stopper 32 which insert the stopper 32 into the upper fixing groove 24a of the guide groove 24 are separated from the upper fixing groove 24a. And a release end 44b for pressing down to the lower fixing groove 24b of the guide groove 24 is further provided.

In addition, the guide groove 24 is provided with a stopper 32 which slides along the locking step 44. Accordingly, the stopper 32 serves to keep the headrest 10 rotated at a predetermined angle while sliding along the locking jaw 44, and the pressing end formed on both sidewalls of the bracket 40 when released. It is configured to be separated from the upper fixing groove 24a of the guide groove 24 by the 44a and the release end 44b. This will be described in the following FIG. 3.

3 is an exploded perspective view showing the tilt structure of the headrest according to the present invention, in which the pressing end 44a and the release end 44b of the bracket 40 are shown in detail.

A plurality of locking jaws 44 are formed on the upper surfaces of both sidewalls of the bracket 40 so that the stopper 32 slides, and the stopper 32 is formed on the top of the locking jaws 44 by the guide groove 24. Thus, the inclined portion 44c for vertically moving upwards is formed. Moreover, the press end 44a which inserts the stopper 32 which slid along the inclination part 44c into the upper fixing groove 24a of the guide groove 24 is formed.

When assembling the bracket 40 to the guide rods 20 and 26, the fixing holes 42 formed on the sidewalls of the bracket 40 and the pin holes 22 of the guide rods 20 and 26 are aligned with each other. Insert the fixing pin 30 to combine. Guide grooves 24 having upper fixing grooves 24a and lower fixing grooves 24b are formed at upper ends of the guide rods 20 and 26. Moreover, the stopper 32 is provided with the guide part 32a which slides along the guide groove 24. As shown in FIG.

In the tilt structure having such a configuration, when the headrest 10 is rotated, the stopper 32 moves along the inclined surface of the locking step 44 as shown in FIGS. 4A and 4B. Next, the headrest 10 is supported by being engaged with the locking jaw 44.

In this state, when the headrest 10 is further rotated, the stopper 32 starts to move along the guide groove 24 while ascending along the inclined portion 44c formed in the side wall. At this time, when the stopper 32 is in contact with the pressing end 44a, the stopper 32 is inserted into the upper fixing groove 24a of the guide groove 24, as shown in FIG. The engagement state between the stopper 32 and the catching jaw 44 is released, and the bracket 40 returns to its original position while rotating to the elastic force of the return spring 46. One end of the return spring 46 is fixed to the side wall of the bracket 40, and the other end is fixed to the guide rods 20, 26.

When the guide rods 20 and 26 are rotated by the return spring 46 to return to their original positions, the stopper 32 is released by the release end 44b of the upper fixing groove 24a of the guide groove 24. After being separated from, by lowering the lower fixing groove (24b) by its own weight, it is engaged with the locking jaw 44 again to support the headrest (10).

According to the present invention described above, there is an effect of increasing the convenience by appropriately adjusting the installation angle of the headrest in accordance with the body shape of the occupant.
