Description

Improved armchair.

Technical sector

The present invention is related to Armchairs that are arranged in movie theaters, congress halls, etc. and that are generally set up in rows to take advantage of the space, proposing an armchair of that type, in the that both the seat and the backrest are incorporated in mounting articulated, being able to swing both between a folded position and a position of use.

State of the art

The equipment of movie theaters, movie theaters congresses and other similar premises, it is usually determined with seats distributed in an organization of parallel rows, going in each of the rows a succession of joined seats sharing common armrests between them, which allows take advantage of space optimally.

Between the rows of seats a separation is left  suitable for users to sit in a position relatively comfortable without impediment by the corresponding row consecutive seats located in front, determining said separation also some aisles between the rows of seats, which allow users to walk around and facilitate the work of  cleaning.

There is also a safety regulation that requires a minimum distance between consecutive rows of seats, when these are not used, to ensure adequate evacuation conditions through the aisles that remain between the rows of seats.
tacas

So that the mentioned aisles between the rows  of seats are clear when the seats are not used, thus facilitating the indicated functions of evacuation, ambulation and / or cleaning, the structuring of the seats with the tilting seat between a horizontal position of use and a vertical stowed position.

However, the seats are usually formed with the backrest slightly tilted back, to favor the convenience of use, which also determines interference in the corridors between the rows of seats, limiting the space free from such aisles.

Object of the invention

In accordance with the invention an armchair is proposed  developed according to a constructive embodiment that allows locating both the seat and the backrest in a folded position, providing advantageous features to free the aisle space between rows of seats in the application facilities.

This armchair object of the invention consists of a conventional structure formed by two sides, among which include a seat and a backrest, going the seat in a mount swingarm between a horizontal position of use and a vertical stowed position.

According to the invention, the backrest is also arranged in an articulated assembly, with the possibility of tilting between a position of use in backward inclination and a position of vertical folding, incorporating a mechanism that tends to place the backrest in the vertical position when the respective armchair be
vacates

You get a seat that allows comfort  of the user by positioning the backrest in tilt back, and also when the chair is not used set is collected in a folded that completely eliminates the interference in the separation aisles between the rows of seats, with the backrest, just like the seat, in a position in the width of the chair's bottom.

The backrest pivot joint is established  associated with at least one connecting rod housed on one side of the armchair, said connecting rod attached to a gas cylinder that acts tending to place the backrest in the vertical position, making said cylinder also a damping function that determines a comfortable operation and without sudden movements of the backrest between use and folding positions.

Said crank of the backrest rotation mechanism it also plays at the top of a groove in the structure of the corresponding armrest side, to keep the backrest of safe and resistant way in the inclined position of use; while in the opposite direction it plays butt against a support susceptible to regulation, by which the vertical position of the backrest to match aesthetically in alignment with the backs of the other seats of the same row in the application installation.

With all this, said armchair object of the invention results from certainly advantageous features, acquiring its own life and preferential character with respect to conventional seats of the same type.

Detailed description of the invention

The object of the invention relates to an armchair that are arranged in rows in movie theaters, congress halls and similar premises, this armchair being provided with an embodiment that allows folding folding more effective than that of conventional seats of the same application
cation

The recommended armchair consists of conventional two-sided (1), on which are arranged two armrests (2), going between said sides (1) a seat (3) and a backrest (4), composing all this a structural set  rigidly attached to the seat assembly assembly.

According to the conventional arrangement, the seat (3)  It is incorporated into an articulated assembly that allows you to swing between a horizontal position and a vertical position, so that for the use of the chair said seat (3) is lowered to the horizontal position, while when the chair is not used the seat (3) is raised to the vertical position to determine a disposition collection of the armchair.

According to the invention, the backrest (4) of the armchair is also arranged in an articulated assembly, being able to swing between a backward position, as in the Figure 3, and a vertical position, as in Figure 2.

In this way, by positioning inclined backrest (3) backwards the comfort of the use of the armchair while the vertical positioning of said backrest (3) allows a greater recollection of the armchair when it it is not used, since in this vertical position the backrest (3) is included in the bottom width of the armchair, without protruding backward.

In relation to the mounting joint of the backrest (4) there is an associated actuator mechanism that is housed on one of the sides (1) of the armchair, there may be a equal mechanism on each side (1) of the armchair, without that this alters the concept.

Said actuator mechanism consists of a connecting rod (5),  which is arranged coupled in solidarity turn assembly with respect to of the shaft (6) of the articulated backrest assembly (4), being attached to said connecting rod (5) a gas cylinder (7) that acts with a thrust constant over her.

In this way, the backrest (4) is subjected to through the connecting rod (5) and the shaft (6), to a tendency towards vertical position, thanks to the action exerted by the cylinder (7), whereby when the armchair is not used automatically the backrest (4) is placed in the vertical position, with the armchair being folded so that the backrest (4) does not protrude backwards, while when the chair is used, the user with his own weight makes tilting the backrest (4), against the action of the cylinder (7), to the position tilted back, in which the user support It is more comfortable.

The cylinder (7) is of a damped speed in the final course of his career, both ways, which it also confers a function of said cylinder (7) also as a buffer for backrest movements (4) between vertical and inclined positioning situations, causing these movements are smooth and without abruptness in the end of the routes.

In the situation that corresponds to the position inclined of the backrest (4), the connecting rod {5) abuts its end in a groove (8) of the armrest structure (2) located on the side (1) in which the mechanism is housed, so that the weight of the backrest (4) and the user who relies on it, not discharge on the cylinder (7), but it is supported in a way safe and resistant by the connecting rod (5) in its support on the armrest structure (2). The armrest (2) is held in one rigid way on the corresponding side (1), by means of a anchor (9), thus ensuring the strength of the crank stop (5) to support the backrest.

In the opposite direction, that is, in the situation  corresponding to the vertical position of the backrest (4), the connecting rod (5) butt on a support (10) fixed on the structure of the side (1) of the armchair, said support (10) being provided so which can be regulated to advance or delay the crank cap (5) on it, which allows to adapt the vertical positioning of the backrest (4), to match properly in alignment with the backrests of the seats incorporated in the same row of the installation.

To stiffen the structural assembly of the armchair in this embodiment, between the sides (1) a brace (11), which extends transversely being fixed by its ends to the respective sides (1) of the armchair, without interfere with the movement arrangements of the seat (3) and of the backrest (4) between the respective positions of use and of retracted
