The present invention relates to a headrest. More specifically, the present invention relates to a headrest having a box-shaped inner cover and a pad attached to the front portion of the inner cover to elastically support the seater's head from the rear.

In the headrest of a vehicle seat, a headrest in which a pad that elastically receives the head of a seated person is set on the front portion of a resin inner cover is known. As a result, the inner cover can support the pad from the back surface in a plane shape. In Patent Document 1, the inner cover is divided into front and rear parts, and the front side cover and the rear side cover are assembled so that their peripheral edges are fitted to each other. As a result, the peripheral edges of the front cover and the rear cover are firmly bonded to each other by supporting each other.

Japanese Patent No. 5744508

However, when the rear cover is assembled with a gap so as to surround the front cover from the outer peripheral side, the peripheral edge of the rear cover tends to bend. As a result, the internal structure of the headrest may be exposed or the design of the headrest may be destroyed. Therefore, the present invention provides a headrest capable of suppressing bending of the inner cover without exposing the internal structure of the headrest.

In order to solve the above problems, the headrest of the present invention takes the following means.

That is, the headrest of the present invention is a headrest having a box-shaped inner cover and a pad attached to the front portion of the inner cover to elastically support the seater's head from the rear. The inner cover is divided into front and rear parts, a front cover attached to the rear surface of the pad and a rear cover attached to the front cover from the rear. The rear cover has an overhang that projects the front cover from the outer peripheral side with a gap. One of the front cover and the rear cover has a first projecting portion that projects so as to be in contact with the other cover from the inner peripheral side or the outer peripheral side.

As described above, since the overhanging portion of the rear cover surrounds the front cover with a gap from the outer peripheral side, it is possible to prevent the internal structure of the headrest from being exposed. Further, when an external force is applied to one cover from the inner peripheral side or the outer peripheral side by the first protruding portion protruding from one cover to the other cover from the inner peripheral side or the outer peripheral side. In addition, since the other cover supports the one cover by the first protrusion, the bending of the inner cover can be suppressed.

Further, the headrest of the present invention may be further configured as follows. The other cover also has a second protruding portion that projects so as to be in contact with the one cover from the inner peripheral side or the outer peripheral side.

Therefore, the first projecting portion and the second projecting portion form a structure in which one cover and the other cover support each other, so that the bending of the inner cover can be further suppressed.

Further, the headrest of the present invention may be further configured as follows. The first protruding portion and the second protruding portion are arranged alternately on one surface of the inner cover.

With the above configuration, the bending of the inner cover can be suppressed more effectively without the first protruding portion and the second protruding portion interfering with each other.

Further, the headrest of the present invention may be further configured as follows. The headrest has a skin cover that covers the pad from the front side. The end of the skin cover is fastened to the end of the front cover surrounded from the outer peripheral side by the overhanging portion of the rear cover.

With the above configuration, the skin cover can improve the usability of the headrest. In addition, the skin cover can be attached more firmly than when the skin cover is attached to the pad.

Further, the headrest of the present invention may be further configured as follows. The overhanging portion of the rear cover is configured to be abutted against the skin cover from the rear side.

In this way, the appearance of the headrest can be further improved by forming a continuous outer peripheral surface between the skin cover and the overhanging portion of the rear cover.

Further, the headrest of the present invention may be further configured as follows. Diagonal with respect to the overhanging portion so that the abutting portion of the epidermis cover, which is abutted against the overhanging portion of the rear side cover from the rear side, presses the overhanging portion toward the outer peripheral side by the elastic force against the abutment. It has a structure stretched over. The first protruding portion protrudes from the rear side cover so as to be in contact with the front side cover from the inner peripheral side.

With the above configuration, the first protruding portion is applied to the inner peripheral surface of the front cover, so that the overhanging portion of the rear cover can be prevented from bending toward the outer peripheral side.
