Headrests for seats. (Machine-translation by Google Translate, not legally binding)

DESCRIPTION

The present invention relates to a headrest for armchairs, which allows its assembly of the upper part of the armchair backrest easily and also allows the headrest to be fixed so that it cannot be unduly disassembled by unauthorized persons.

The seats currently used for showrooms and conferences include a headrest for user comfort, the chair being usually upholstered. The head restraint can be formed in the upper part of the backrest or it can be an independent part of the rest of the armchair fixed in the upper part of the backrest of the same.

In the event that the headrest is an independent part of the rest of the armchair, the headrest is fixed to the backrest, in some cases, by means of headrest projections that are inserted into complementary recesses provided in the upper part of the backrest. These headrests have the disadvantage that they can be easily removed by unauthorized persons, since these seats are intended for public places.

With the head restraint of the invention, the aforementioned problems are resolved, presenting other advantages that will be described.

The headrest for armchairs of the invention is characterized by the fact that it comprises a housing that has a rib that defines an upper part and a lower part, said nerve being fixed on the back of the armchair.

Thanks to this feature, the head restraint can be mounted more easily than the head restraints currently known and, at the same time, allows the head restraint to be fixed so that it cannot be unduly disassembled.

Advantageously, the upper part of the housing defines a cavity in which an upholstered piece independent of the rest of the headrest is coupled with pressure, which allows the headrest upholstery to be easily replaced and facilitates the assembly and disassembly of the headrest.

Preferably, the fixing means of the headrest to the back of the chair are arranged in the rib and in the lower part of the housing.

Following a preferred embodiment, the upholstered part independent of the headrest comprises a series of bars that are snapped into complementary recesses provided in the upper part of the housing.

Preferably, the fixing means of the headrest to the backrest are screws.

For the best understanding of what is described herein, some drawings are attached in which, just by way of a non-limiting example, a practical case of head restraint is represented.

In said drawings, Figure 1 is an elevational view of the upper part of a partially sectioned armchair, comprising the headrest of the invention, the upholstered parts of the armchair being represented;

Figure 2 is an elevation view similar to Figure 1, in which the upholstered seats of the armchair are not placed, the section being made in a different plane to the section of Figure 1;

Figure 3 is an elevational view of the headrest of the sectioned invention; and Figure 4 is a front elevational view of the upholstered part of the headrest of the invention.

As can be seen in the figures, the headrest for armchairs of the invention comprises a housing 1 provided with a rib 2 defining an upper part and a lower part 1b. The rib 2 is attached to the upper part of the backrest of the chair 3, preferably by means of screws 4.

The upper part of the housing is defined by a cavity in which an upholstered piece 5 is attached, which is independent of the rest of the headrest.

As can be seen in the figures, the carcass 1 of the headrest is fixed to the upper part of the armchair backrest by means of screws 4a, 4b, 4c arranged in the rib 2 and in the lower part of the carcass 1b.

The upholstered pieces, both the headrest and the backrest and the seat, are independent parts of the rest of the armchair structure, as mentioned above. These pieces are one-piece blocks of spongy nature, molded directly on an interior reinforcement shell, and which are coated on their face, by direct molding, by means of an upholstery sheet.

As can be best seen in Figures 3 and 4, the coupling of this upholstered piece 5 is carried out by means of a pair of bars 6 that are introduced in complementary recesses 7 arranged in the cavity of the upper part of the housing. As can be seen, the recesses 7 are arranged in opposite directions, which allows the fixing of the upholstered piece 5 to be better.

In this way, you get a headrest very easy to place, also preventing undue disassembly by unauthorized persons. The placement of the headrest is done by arranging the rib of the housing on the upper part of the backrest of the armchair. The screws are then fixed by fixing the housing to the backrest and, finally, the upholstered independent parts are snapped together.

The materials used in the manufacture of the headrest components, shapes and dimensions thereof and all the accessory details that may be presented will be independent of the object of the invention, as long as they do not affect their essentiality, which is defined in the attached claims.
