Description

A headrest of a car

The present invention relates to a head restraint of an automobile, and more particularly, a head restraint of an automobile which can be separately operated by an upper support and a lower support so that the head and neck of the occupant can be comfortably leaned at the same time as needed. It is about.

In general, a headrest is installed above the seatback, which forms a seat, and this headrest protects the head of passengers, including the driver, from being injured by a moment when the vehicle suddenly stops while driving or collides with another vehicle. On the other hand, when the seat back is laid back to rest or sleep in a comfortable position to serve as a pillow to support the occupant's head.

In the case of the prior art, as shown in FIG. 4, the headrest 120 has a metal positioning bar 130 fixed to the headrest 120, and the position fixing bar 130 is fitted above the seat back 110. The insertion hole 132 is formed so that the insertion hole 132 is inserted into the position fixing bar 130 of the headrest, and then assembled and fixed, so that the occupant seated on the seat can rest on the seat back 110. Headrest 120 has achieved a combined fixed form.

However, the headrest 120 is installed in a diffractive structure that can be folded back and forth instead of the fixed structure position fixing bar 130 in a more improved form, but can only lean the head of the passenger to the neck There was no function to rest, and accordingly, there was a problem that the fatigue of the neck is increased during the long run, and the occupant is easily tired.

Therefore, the present invention was devised to solve various problems of the headrest installed in the conventional vehicle, and if necessary, the upper support and the lower support can be separated and operated so as to comfortably support the head and neck of the occupant at the same time. The purpose is to provide a headrest for a car.

In order to achieve the above object of the present invention, the upper support and the lower support are separated and coupled to the position fixing bar installed on the seatback upper side, the upper support is the upper form plate at the end of the position fixing bar inserted into both sides therein The lower support has a rotary lever coupled to the lever rod end by a rod rod coupled to the position fixing bar inserted into both sides of the lower support and a lower rod attached to the rod rod coupled to the rod rod end. A two-section detachable headrest is configured to be pivotally moved by rotation of the lever rod, and the lever rod may protrude forward than the upper support when the lower portion of the lower support is pivoted toward the neck of the occupant. It is characterized in that coupled to the position fixing bar corresponding to the upper middle point of the lower support.

When the headrest installed in the seatback is configured as described above, when the rotary lever installed on one side of the lower support is rotated, the lever rod coupled to the rotary lever is rotated and the lower form plate coupled to the middle of the lever rod pivots vertically. The lower part of the lower support, which was in contact with the upper side, is turned toward the neck of the occupant and protrudes in front of the upper support. Therefore, the occupant can comfortably support the head and neck by leaning against the upper support and the lower support of the headrest at the same time. .

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

Figure 1 shows the headrest outer structure of the present invention, Figure 2 shows the inner structure of the headrest of the present invention, the headrest protecting the occupant's head is configured to be separated into the lower support and the upper support both inside It is coupled to the upper seatback through the position fixing bar which is inserted into the longitudinal direction.

The upper support 22 is coupled to the upper form plate 32 of the rectangular plate shape is coupled to the end of both position fixing bar 30 inserted therein while maintaining the shape around the position fixing bar 30 Position is fixed.

The lower support 24 is coupled to each of the rod bushing 44 is formed on the inner circumferential surface of the two position fixing bar 30, which is passed through the inside, the screw thread on the outer circumferential surface on both rod bushing 44 Lever rod 42 is formed is fastened.

In addition, a lower plate (34) having a plate-shaped cross section bent to the middle portion of the lever rod (42) between both rod bushes (44) is coupled to the lower support centering around the position fixing bar (30). While maintaining the shape of 24, the lower support plate 24 is pivoted while the lower form plate 34 is interlocked with the upper fixing bar 30 as the axis according to the rotation of the lever rod 42. The bottom portion 25 of the lower support can be moved to the neck portion of the occupant 50, the outer end of the lever rod 42 is coupled to the rotary lever 40, the handle is integrated.

In addition, the lower profile plate 34 which pivots the lever rod 42 while maintaining the shape of the lower support 24 on the axis is the bottom portion 25 of the lower support 24 which is in contact with the upper side of the seat back 10. When coupled to the neck of the occupant 50 is coupled to the corresponding position of the position fixing bar 30 of the middle upper point inside the lower support 24 so that it can protrude forward than the upper support 22.

The headrest 20 configured as described above and installed on the seat back 10 has a lever rod 42 coupled to the rotation lever 40 when the rotation lever 40 installed on one side of the lower support 24 is rotated. The lower support 24 is rotated about both rod bushing 44 which is fixed to the position fixing bar 30 on both sides inside.

As the lever rod 42 rotates, the L-shaped lower form plate 34 coupled to the middle of the lever rod 42 is vertically turned, and the lower support 24 is also rotated by the lower form plate 34. The bottom portion 25 of the lower support 24, which is in contact with the seatback 10 and upward while turning vertically in the clockwise direction, is turned toward the neck of the occupant 50 to protrude forward than the upper support 22, and thus the occupant 50, the head and neck can be comfortably leaned against the upper support 22 and the lower support 24 at the same time forming the headrest 20.

As described above, according to the headrest of the vehicle according to the present invention, if necessary, by rotating the lower support separated from the upper support to project the lower support forward than the upper support to protect the occupant's head at the same time the neck of the passenger By allowing the user to comfortably lean and support, it provides a convenience effect that allows a passenger to rest more comfortably during a long time driving.
