Description

The present invention relates to headrests. More specifically, it 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 head of a seated person from behind.

2. Description of the Related Art Headrests of vehicle seats are known in which a pad for elastically receiving the head of a seated person is set on the front surface of a resin inner cover. Thereby, the inner cover can planarly support the pad from the back surface. In Patent Document 1, the inner cover is divided into front and rear parts, and the front and rear covers are assembled so that their peripheral edges are fitted to each other. As a result, the peripheral edge portions of the front cover and the rear cover support each other and are firmly connected.

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 damaged. SUMMARY OF THE INVENTION Accordingly, the present invention provides a headrest that can suppress the deflection 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 employs the following means.

That is, the headrest of the present invention is a headrest having a box-shaped inner cover and a pad that is attached to the front portion of the inner cover and elastically supports the head of a seated person from behind. The inner cover is divided into a front cover attached to the rear surface of the pad and a rear cover attached to the front cover from behind. The rear cover has a protruding portion that protrudes so as to surround the front cover from the outer peripheral side with a gap therebetween. One cover of the front side cover and the rear side cover has a first protrusion that protrudes in such a manner as to be brought into contact with the other cover from the inner peripheral side or the outer peripheral side.

In this way, since the projecting portion of the rear cover surrounds the front cover from the outer peripheral side with a gap, 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 in such a manner as to be applied 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 projecting portion, the bending of the inner cover can be suppressed.

Moreover, the headrest of the present invention may be further configured as follows. The other cover also has a second projecting portion projecting in such a manner as to be brought into contact with the one cover from the inner peripheral side or the outer peripheral side.

Therefore, the one cover and the other cover are configured to support each other by the first protrusion and the second protrusion, thereby further suppressing the bending of the inner cover.

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

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

Moreover, the headrest of the present invention may be further configured as follows. The headrest has a skin cover covering the pad from the front side. The end of the skin cover is fixed to the end of the front cover surrounded from the outer periphery by the projecting portion of the rear cover.

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

Moreover, the headrest of the present invention may be further configured as follows. The projecting portion of the rear cover is configured to abut against the outer 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 outer cover and the projecting portion of the rear cover.

Moreover, the headrest of the present invention may be further configured as follows. The abutted portion of the skin cover, which is abutted from the rear side on the overhanging portion of the rear cover, is oblique to the overhanging portion so that the projecting portion is pushed outward by the elastic force against the abutment. It is a structure stretched over. The first protrusion protrudes from the rear cover so as to be brought into contact with the front cover from the inner peripheral side.

With the above configuration, the projecting portion of the rear cover can be prevented from flexing toward the outer peripheral side by abutting the first projecting portion against the inner peripheral surface of the front cover.

<Assembly of front cover 11 and rear cover 12>
As described above, the split front cover 11 is integrally attached to the pad 20 by the skin cover 30 . Also, the divided rear side cover 12 is integrally assembled with the bracket 50 to which the headrest stay 40 is welded. The front cover 11 is also integrally attached to the bracket 50 as described above. In this manner, the front cover 11 and the rear cover 12 are integrally assembled with each other via the bracket 50, so that the headrest 1 is set in an assembled state.

As a result of the assembly, as described above, the rear projecting portion 12b of the rear cover 12 is set so as to surround the front projecting portion 11b1 of the front cover 11 from the outer peripheral side with a gap. In addition, the tip of the rear projection 12b abuts against the skin cover 30 covering the pad 20 from the rear side (see FIG. 3). Due to the abutment, the rear protruding portion 12b forms an outer peripheral surface that is continuous with the outer cover 30. As shown in FIG. Thereby, the rear side projecting portion 12b can prevent the internal structure of the headrest 1 from being exposed. Further, the upper surface and left and right surfaces of the rear projecting portion 12b are abutted from behind against the oblique extending portion 31 of the outer cover 30 (see FIGS. 7 and 8). This oblique stretched portion 31 corresponds to the "strung portion" of the present invention. Due to the elastic force of the diagonally stretched portion 31 returning to its original position, the upper surface and the left and right surfaces of the rear projecting portion 12b receive a pushing force toward the outer circumference.

However, the first rear rib 12c1 of the rear cover 12 is hooked to the inner peripheral surface of the front projecting portion 11b1 of the front cover 11 (see FIG. 7). As a result, deformation of the upper surface portion and the left and right surface portions of the rear projection portion 12b toward the outer peripheral side is suppressed. On the other hand, when a force is applied to the rear cover 12 to press the rear projecting portion 12b inwardly from the user, the protruding portion 11c1 of the front cover 11 is pushed rearward. The projecting portion 12b is supported from the inner peripheral side, and the second rear rib 12c2 of the rear cover 12 is supported by the front projecting portion 11b1 (see FIGS. 8 and 9). This support suppresses deformation of the rear projecting portion 12b toward the inner peripheral side.

As shown in FIG. 9, in a state where the front cover 11 and the rear cover 12 are assembled together, each projection 11c1 projecting from the front cover 11 and each rear rib 12c projecting from the rear cover 12 are: They are arranged in a staggered manner on each of the left and right surface portions of the inner cover 10 . Also, on the lower surface of the inner cover 10 (not shown), the rear ribs 12c protruding from the rear cover 12 are arranged so as to be sandwiched between the protrusions 11c1 protruding from the front cover 11. As shown in FIG. Due to the arrangement, it is possible to prevent the front ribs 11c and the rear ribs 12c from interfering with each other during the assembly. That is, the staggered arrangement secures a wider width between the protruding portions 11c1 of the front cover 11 and a wider width between the rear ribs 12c of the rear cover 12 than when the arrangement is not staggered. be done. As a result, when the front cover 11 and the rear cover 12 are assembled together, the portions that are brought into contact with the projecting portions 11c1 of the front cover 11 or the rear ribs 12c of the rear cover 12 are easily bent. Therefore, the front cover 11 and the rear cover 12 can be assembled without strong interference. Further, the protrusions 11c1 of the front cover 11 and the rear ribs 12c of the rear cover 12 mutually support the front cover 11 or the rear cover 12, so that deformation and bending of the inner cover 10 can be prevented more effectively. can be effectively suppressed.
