Description

DEVICE FOR HEATING SEATS

The present invention relates to a seat with seat heating device, with or without backrest, on which one or more persons can sit at the same time, this seat being able to be arranged with others one behind the other, said seats being for example benches or rows of chairs or stools.

To heat a room such as a church, a conference room or concert hall, and more particularly people placed on seats, such as benches or rows of chairs or stools, arranged one behind the other in this room, electrical heating systems are generally known, generally arranged in height and equipped with a blower for drawing hot air into said room. This type of heating has the disadvantage of being noisy, creating unpleasant air currents and not to ensure a homogeneous heating of the room and therefore of the people located inside said room.

Individual heaters are also known such as electric heaters or connected to a hot water system. These radiators are unsightly because visible and also do not allow a homogeneous heating of the premises. Indeed, people sitting near the radiators will be properly warmed, however the further away from the radiators and the less their effect is noticeable. Similarly, like the previous heating system, this type of heating does not allow rapid heating up, there is a certain inertia to heat the entire room.

It is also possible to heat a room with an electric floor heating device. This type of heating device, also called "floor heating ", allows a more homogeneous heating mode because it heats the entire slab of the room then by convection the entire volume above said slab, and not only the areas close to said individual heaters. , the heated floors are aesthetic since all the elements heating the slab are inserted into the slab, but for an already existing room, it is necessary to remake a slab equipped with the heating elements on the slab initially made, which generates a significant extra cost In addition, for premises in classified sites such as churches, architects of buildings in France do not accept the establishment of a new slab on a slab with slabs or old tiles.

In addition, all these modes of heating are incompatible with a change of layout and the number of seats in the room.

The present invention aims to overcome these various disadvantages by providing a seat with a seat heating device on which one or more people can sit at the same time, said seat being arranged with other seats one behind the other. other. This seat with heating device is easy to use and allows a rapid and homogeneous heating up since it directly heats the people placed on or near the seat.

In this regard, the present invention relates to a seat with seat heating device, with or without backrest, on which one or more people can sit at the same time, this seat can be arranged with other seats one behind the others, said seat and the others being for example benches or rows of chairs or stools, said seat with heating device being remarkable in that said device heater is at least disposed under the seat cushion and comprises at least a first structure containing a thermal insulation and at least partially covered by a radiating heating element, said first structure being provided with a front face, an upper face and a rear face, the front, upper and rear faces being arranged to be respectively oriented towards the front part of the seat, the bottom of the seat cushion and the rear part of the seat.

It will be no difficulty to understand that this type of seat with heating device allows a great modularity of the arrangement of said seat and other seats since the heater is directly connected to said seats.

Similarly, it is understandable economic interest of this type of heater because being close to people it is not necessary to overheat the volumes.

Other advantages and features will become more apparent from the following description of a seat with a heating device according to the invention, given by way of non-limiting example, with reference to the appended drawings in which:

- Figure 1 is a side view of a seat with heating device according to the invention,

FIG. 2 is a side view of a seat with a heating device according to the invention in a situation with persons,

FIG. 3 is a perspective view of the structure of the seat heating device according to the invention,

- Figure 4 is a side view of a variant of the seat with heating device according to the invention.

We will describe in this example of non execution limiting, a seat with bench type heater to be inserted in one or more rows of benches placed one behind the other, in a church for example. However, the seat with heating device can obviously be a completely different type of seat such as a chair or a stool arranged with others next to one another so as to form rows and rows of rows arranged one behind the other.

With reference to FIGS. 1 to 3, the subject of the present invention is a seat 2 with a bench type heater 1, said heating device 1 being placed under the seat 3 of said bench 2 and comprising a structure 4 of generally tubular shape. , containing a thermal insulation 5 and covered at least in part by an electric heating element 6 advantageously by radiation.

The structure 4 (shown in FIG. 3) is composed of two substantially vertical solid lateral faces 41 and a plurality of longitudinal plates 42 connecting said lateral faces 41 to one another so as to create a volume 43 between said lateral faces 41 and plates. longitudinal 42, said longitudinal plates 42 closing all or part of the volume 43.

The lateral faces 41 are preferably isosceles triangles oriented downwards and whose base is disposed under the seat 3 of the bench 2 substantially horizontally and parallel to said seat 3. The longitudinal plates 42 are then three in number and each connect an edge of a lateral face 41 with the associated edge of the other lateral face 41. In addition, the lateral faces 41 and longitudinal plates 42 completely close the volume 43. Finally, the constituent elements of the structure 4 are advantageously made of wood for obvious reasons of lightness and low conductivity to prevent heat loss.

Once constituted, the volume 43 of the structure 4 is filled by the thermal insulation 5.

Said thermal insulator 5 is of the high density type making it possible to limit the input of the thermal radiation inside the structure 4 in order to promote the diffusion of the radiation towards the outside of the structure 4. For this purpose, the thermal insulation 5 is advantageously obtained from fibers resulting from the recycling of plastic bottles. The assembly consisting of the structure 4 and the thermal insulation 5 is covered with the heating element 6.

In the preferred embodiment, the volume 43 is completely closed by the lateral faces 41 and longitudinal plates 42 thus avoiding any contact between the thermal insulation 5 of plastic fibers and the heating element 6, and therefore any risk of fusion said fibers.

Said heating element 6 is of flexible and deformable type in order to be able to be wound around the structure 4. In addition, for obvious reasons of safety, the heating element 6 is advantageously arranged to be supplied with a very low safety voltage (designates here by very low voltage an electrical voltage ranging from 1 to 44 volts), said heating element 6 is connected to a transformer single-phase or three-phase power. In addition, the heating element 6 makes it possible to obtain a temperature of between 10 and 35 ° C.

In a preferred embodiment, the heating element 6 is a heating sheet advantageously chosen from the group comprising at least the THERMALU® TILE transmitters, the THERMALU® LA CHAPPE LIQUIDE® transmitters, and the THERMALU® CEILING transmitters.

THERMALU® CARRELAGE transmitters, transmitters THERMALU® LA CHAPPE LIQUIDE®, the THERMALU® CEILING transmitters are mainly and respectively intended to be installed under tiled floors, under a floating slab and behind a stretch ceiling. These different emitters are composed of an aluminum strip approximately 0.05 mm thick and 10 to 80 mm wide, said strip forming an electrical circuit and capable of being covered for example with a polyurethane lacquer and / or varnish. This circuit is fixed either between two fiberglass mesh 1 mm thick, or between two PVC films. Thus formed, said emitters, so have a thermal resistivity at 20 ° C of 3.4 x 10 ^"8 ohm / m and an adjustable power flux of 10 to 300 watts / m ^2.

With reference to FIG. 2, it is understood that with such a configuration, the heating device 1 of the bench 2, according to the invention, allows, given its position under the seat 3 of the bench 2, to heat the the lower part of the legs and the upper part of the legs and body of the person (s) sitting on the bench 2, but also the lower part of the legs of the person (s) 8 placed behind the bench 2. The arrows of Figures 1, 2 and 4 represent the thermal radiation emitted by the heating device 1.

Indeed, the front face 9 of the structure 4 of the heating device 1, which is oriented towards the front part of the bench 2, heats the lower part of the legs of the person (s) 7 seated (s) ) on the bench 2. Similarly, the upper face 10 of the structure 4 of the heating device 1, which is oriented towards the bottom of the seat 3 of the bench 2 heats the upper part of the legs and the body of the ( or person (s) sitting on the bench 2. Finally, the face rear 11 of the structure 4 of the heater 1, which is oriented toward the rear portion of the bench 2, heats the lower legs of the person (s) 8 behind the bench 2.

Insofar as the persons 7, 8 to be heated are in the vicinity of the heating device 1, it is easy to understand the economic interest of the latter. Indeed, since it is no longer necessary to heat a large volume, the heat losses are very limited, the inertia of the heating device 1 is very low and the heating temperature is homogeneous. In addition, in order to limit the power consumption, it will be possible to stop heating the unoccupied benches 2. For this purpose, the heating device 1 may be coupled to a switch positioned for example on one of the lateral faces 41 of the structure.

Similarly, the bench 2 with heating device 1, according to the invention, allows a great modularity in the arrangement of said bench 2 with other benches. Indeed, it will suffice to connect or disconnect the electrical connection of one or more benches 2 with heating devices 1 to change said provision.

It is well understood that the structure 4 of the heating device 1 may have a section other than isosceles triangular such as, for example, elliptical, circular or polygonal, the structure 4 may therefore have other faces than the front, upper and lower faces. rear 9, 10, 11, without departing from the scope of the present invention. Similarly, the latter may be non-planar or left, without departing from the scope of the present invention.

However, an isosceles triangle-shaped section is very economical because the structure 4 comprises only three longitudinal plates 42, and allows a good orientation of the front, upper and lower faces. rear 9, 10, 11 of the heating device 1. This section also allows optimal heating for theater seats or even concert hall for example.

With reference to FIG. 4, in an alternative embodiment and in the case of a seat 2 with a backrest, the heating device 1 may comprise several structures. Thus, it is possible to place a first structure 4 of section in the form of an isosceles triangle under the seat 3 of the seat 2, as described above, and a second structure 14 of section advantageously in the form of a vertically elongated flat rectangle, behind the back of said seat 2. In addition, the second structure 14 is at least provided with a front face 17 and a back face 18 arranged to be respectively oriented towards the front and rear part of the seat 2. It is then clear that this seat 2 with a heating device 1 with two structures 4, 14 also makes it possible to heat the back of the person (s) seated on said seat 2 and the upper part of the legs or the body of the (or ) person (s) behind said seat 2. Said second structure 14 is similar to the first structure 4 and contains a thermal insulator 15 and is at least partly covered by a heating element 16 radiating.

Like the first structure 4, the second structure 14 may have a section other than that described such as, for example, elliptical, circular or polygonal, with non-planar or left faces, without departing from the scope of the present invention.

The two structures 4, 14 may be coupled together or independent of each other. In this second case, it will be possible to selectively use one or other of the structures 4, 14, or to use them simultaneously. Finally, the seat 2 with heating device 1 may include different types of supports to allow the attachment of said heater 1 on the seat 2 or on the floor and / or different types of protection including the degradation of acute angles of the structures 4 , 14 with reinforcements placed on said angles, without departing from the scope of the present invention.

According to an alternative embodiment not shown, the heating device 1 is disposed under the seat 3 of said bench 2 and comprises a first structure 4 and optionally a second structure 14, each of the two structures 4, 14 being of generally tubular shape , containing a thermal insulator 5 and covered at least in part on its inner surface by an electric heating element 6. In this configuration, each of the two structures 4, 14 may preferably be made from solid metal sheets, may be heated by said electric heating element 6 and may transmit this heat energy including radiation for heating the people placed on the bench or near the latter. In this configuration, each of the two structures 4, 14 may also preferably be made from at least partly perforated metal sheets, advantageously aluminum alloy perforated sheets, said electric heating element 6 may then heat the persons placed on the bank 2 or near the latter by radiation through the perforated zones of said structures 4, 14, the structures 4, 14 then serving in this case only protection to prevent damage including the heating element 6. It is understood although, in this embodiment, it will be necessary to check the good behavior of the thermal insulator 5 when it is in contact with the heating element 6. The present invention applies more particularly to pews but it is obvious that the example just given is only a particular illustration in no way limiting as to the fields of application of the invention.
