Description

  The present invention relates to a headrest that is applied particularly to the second and third rows of seats and that reduces the amount of protrusion from the seat back during storage, thereby making it easier to ensure the driver's rear view.

  Conventionally, there is JP, 2007-106292, A as a technique of such a field. The headrest described in this publication includes an upper portion that contacts the top of the seat back in the retracted state, that is, the lowest position, and a front drooping portion that extends downward from the upper portion so as to overlap the front surface of the seat back in the retracted state. have. According to this headrest configuration, when the headrest is raised, the front hanging part firmly supports the occupant's head, and when the headrest is lowered and stored, the front hanging part is located on the front of the seat back. The vehicle is lowered until it overlaps, and the driver's rear view is easily secured. In addition, when the seat back is retracted, the headrest does not protrude greatly from the top of the seat back, and therefore the headrest is unlikely to become an obstacle when the seat back is tilted forward.

  However, in the conventional headrest described above, if the headrest is left in the raised state, the headrest becomes in the way and it becomes difficult to secure the driver's rear view. There is a problem that the burden is imposed.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a headrest that facilitates securing a driver's rear field of view even in a state where it is raised to a use position.

The present invention, in a headrest having an upper portion that contacts the top of the seat back in the retracted state and a front drooping portion that extends downward from the upper portion so as to overlap the front surface of the seat back in the retracted state,
The front hanging part is provided with a through hole that can be visually recognized by the driver.

  The retractable headrest generally used for the second and third row seats has a front hanging portion that supports the head of the occupant at the use position, but the front side of the headrest according to the present invention. The hanging part is provided with a through-hole that can be visually recognized by the driver, so it is easy to achieve both high support for the passenger's head and securing the driver's rear view at the position of use. Can do. Therefore, even if the occupant does not always lower after using a retractable headrest with a front hanging part, it is possible to ensure the driver's rear view and increase the size of the headrests in the second and third rows. The feeling of holding the head can be improved, and the comfort can be improved. Moreover, by providing a through hole, the weight of the headrest can be reduced, and the headrest can be raised by placing a finger on the through hole of the stored headrest, so the front hanging part overlaps the front of the seat back. The headrest can be easily lifted even when

Further, it is preferable that the through holes have a horizontally long shape and a plurality of the through holes are arranged side by side.
By adopting such a configuration, the driver's rear view at the use position can be better secured without deteriorating the support performance of the occupant's head.
Furthermore, it is more preferable that a reinforcing material is present between the through holes arranged in parallel in the vertical direction.
By adopting such a configuration, it is possible to further enhance the support performance of the occupant's head without reducing the driver's backward visibility.

Further, it is preferable that the upper part and the front drooping part have a substantially inverted L-shaped cross section.
The headrest having such a configuration has a headrest stay exposed on the rear side, but is optimal for a third row seat having no seat on the rear side, and can be said to be an optimal shape for weight reduction.

In addition, the upper portion, the front drooping portion, and the rear drooping portion extending downward from the upper portion so as to overlap the back surface of the seat back in the retracted state have a substantially inverted U-shaped cross section. It is preferable that another through hole aligned with the through hole of the front side hanging part is provided in the rear side hanging part.
The headrest stay is not exposed on the rear side, and is optimal for, for example, a second row seat having a seat at the rear.

  According to the present invention, even if the retractable headrest has a front hanging part, the driver's rear view at the use position can be easily secured.

It is a perspective view which shows 1st Embodiment of the headrest which concerns on this invention. It is sectional drawing of the headrest shown by FIG. It is a perspective view which shows 2nd Embodiment of the headrest which concerns on this invention.

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

  As shown in FIGS. 1 and 2, the headrest HR as an integral foam molded product is formed by curing a bag-like trim cover 2 and a foaming liquid (for example, foaming urethane) injected into the trim cover 2. The pad body 3 includes a pair of left and right headrest stays 5 extending downward from the headrest frame 4 in the pad body 3.

  The trim cover 2 is made of a two-layer type made of a skin made of a synthetic leather having no air permeability and a wadding made of a slab urethane foam material fixed to the back surface of the skin.

  The headrest HR tilts the front surface 7 so as to overlap the front surface 7 of the seat back SB in the retracted state, that is, the substantially horizontal and flat upper portion 10 that contacts the top portion 6 of the seat back SB in the retracted state. And a flat front hanging part 11 extending obliquely downward from the upper part 10 with substantially the same inclination.

  In such a headrest 1 having a substantially inverted L-shaped cross section, the flat upper portion 10 is in close contact with the top portion 6 of the substantially horizontal seat back SB in the retracted state. As a result, the amount by which the upper part 10 protrudes from the top 6 of the seat back SB can be reduced in the retracted state of the headrest HR, so that it is difficult to disturb the driver's rear view, and when the headrest HR is retracted, the seat back Since the headrest HR does not protrude greatly from the top of the SB, the headrest HR is unlikely to get in the way when the seat back SB is moved forward.

  Further, in the headrest 1 having a substantially inverted L-shaped cross section, the flat front side hanging portion 11 is in close contact with the front surface 7 of the inclined seat back SB. Thereby, in the retracted state of the headrest HR, the amount by which the front hanging portion 11 protrudes from the front surface 7 of the seat back SB can be reduced, so that the seat back SB is in a substantially flat state in the forward-turned state of the seat back SB. Easy to do.

  Further, the front side hanging portion 11 is provided with a plurality of, for example, two through-holes 12 having substantially the same shape that are visible in the rear and are arranged side by side. Each through hole 12 is formed in a horizontally long shape, and is composed of linear and parallel flat surfaces 12a and 12b opposed vertically and curved surfaces 12c and 12d that are symmetric. Thus, by ensuring that the through holes 12 are horizontally long and arranged side by side in the vertical direction, the driver's rear view can be better secured.

  In order to prevent deformation between the upper through hole 12 and the lower through hole 12, it is preferable that the lateral beam 4 a of the headrest frame 4 is included in this portion as a reinforcing material.

  The retractable headrest generally used for the second and third row seats has a front hanging portion that supports the head of the occupant at the use position, but the front hanging portion of the headrest HR described above. 11 is provided with a through-hole 12 that can be visually recognized from the rear, so that it is possible to easily achieve both high support performance for the occupant's head and securing the driver's rear view at the use position. Therefore, even if the occupant does not always lower after using the retractable headrest HR having the front hanging part, it is possible to secure the driver's rear view, and the front hanging part 11 of the second or third row headrest HR can be secured. By increasing the size, it is possible to improve the feeling of holding the head of the occupant and improve the comfort.

  In addition, the weight of the headrest HR can be reduced by the through hole 12, and the headrest HR can be raised by putting a finger on the through hole 12 of the headrest HR in the retracted state. The headrest HR can be easily lifted even when the headrest HR overlaps the front surface 7 of the head.

  Although the headrest HR having such a configuration has the headrest stay 5 exposed on the rear side, the headrest HR is optimal for, for example, a third row seat having no seat on the rear side, and can be said to be an optimal shape for weight reduction.

  It goes without saying that the present invention is not limited to the embodiment described above. For example, as shown in FIG. 3, the other headrest HR1 includes a curved upper portion 20, a front hanging portion 21, and a rear side extending downward from the upper portion 20 so as to overlap the back surface 9 of the seat back SB in the retracted state. The drooping portion 22 has a substantially inverted U-shaped cross section. The headrest stay 25 extends directly below the upper portion 20 and is disposed between the front hanging portion 21 and the rear hanging portion 22.

  Such a headrest HR1 is optimal for a second-row seat, for example, in which the headrest stay 25 is not exposed on the rear side and the seat is on the rear side.

  Further, a substantially rectangular through hole 23 is provided in the front drooping portion 21, and a through hole 23 in a position aligned with the through hole 23 in the front drooping portion 21 is provided in the rear drooping portion 22. The hole 23 has the same shape and can ensure the driver's rear view.

Further, the above-described through holes 12 and 23 may be either singular or plural, and the shape is not limited to those shown in the figure, but may be any of, for example, a triangle, a square, a circle, an ellipse, a polygon, and a star. There may be.
In addition, when the above-mentioned through-holes 12 and 23 are made into one, the shape and size may be limited to those that can ensure the protection performance of the occupant's head. Accordingly, if the plurality of through holes 12 and 23 are arranged vertically, and the transverse beam 4a of the headrest frame 4 is provided as a reinforcing material between the upper and lower through holes, the protection performance of the occupant's head is lowered. It is possible to easily ensure the driver's rear view at the position where the headrest HR is used.

  Further, a three-layer type trim cover made of a non-breathable film (polyurethane film, polyethylene film, etc.) bonded to the skin, the wadding, and the back surface of the wadding is also applicable.
