    Adjustable seat.
    DESCRIPTION
    The invention relates to a seat, consisting of a seat body, a backrest fixed on the seat body with adjustable inclination, a seat part fixed to the seat body with sliding and adjustable inclination, and a headrest pivotally attached to the seat neck and constituting an extension of the backrest, knowing that in a first use position, the seat portion is moved towards the back of the seat body and is oriented substantially horizontally , the backrest is strongly inclined and is moved by its lower end towards the back of the seat neck, and the headrest is oriented approximately horizontally and covers the edge of the upper rear edge of the seat body, and knowing that in a second position of use, the seat portion is moved forward protruding from the front edge of the seat body and is oriented by being inclined downwardly downwardly towards the back of the seat body, the back is slightly inclined and is moved by its lower end towards the front edge of the seat body, and the headrest is oriented approximately vertically.
    Such seats can be set in two different comfort positions. In a first use position, the seat portion is oriented substantially horizontally, possibly sloping slightly downward towards the rear of the seat, the seat part being further moved towards the seat. back of the seat body. In this position of use, the backrest is straightened with a relatively steep slope. The lower end of the backrest is also moved towards the rear of the seat neck, in correspondence with the displacement of the seat portion towards the rear. The corresponding headrest, which can be almost an extension of the backrest portion, is pivotally depressed backward. In this position, the seat is a simple piece of furniture seat, knowing that as the headrest is lowered by pivoting backwards, we obtain a low height of the entire seat in this position, so that headrest does not affect the appearance of the seat; in particular, it does not constitute an obstacle protruding above the seat.
    In a second use position, which corresponds to a comfort position, the seat portion is shifted forwards and lowered by its rear end. At the same time, the backrest portion is moved into a comfortably inclined position, the lower end of the back portion following the forward movement of the seating portion, so that the two portions remain substantially connected. In this position, the head restraint is straightened or must be straightened, so that it is a support for the user's head protruding from the upper end of the backrest portion. It is usual for such seats that the raising and lowering of the headrest is performed separately by hand by the user, so that the pivoting movement of the headrest is not effected by forced manner due to the displacement of the seat portion and the displacement of the back portion, but requires separate handling.
    From this state of the art, the invention aims to provide a seat of the generic type in which the displacement of the seat portion and the backrest of the first use position in the second position of use and back in the first use position is accompanied by a simultaneous movement of the headrest without this requires special handling of the user.
    In order to achieve this goal, it is proposed that the headrest be connected to the backrest by means of an actuator by means of which the headrest is, when the file is in the first position of use. forcibly moved in the rearwardly directed horizontal position and by means of which the headrest, when the backrest (2) is in the second position of use, is pivotally raised in the second position 'use.
    With this arrangement, it is obtained that the headrest is, in the first use position, oriented approximately horizontally by being lowered by pivoting forcibly rearward and, in the second position of use, is raised forcibly in the support position. Special handling by the user is not necessary for this purpose, because by only moving the seat part, which is coupled the movement of the backrest, it also provides the pivoting of the headrest in the first or respectively the second position of use.
    Preferably, it is here provided that the backrest is connected to the seat body via an articulated quadrilateral whose first link is formed by a first fitting fixed on the side and at the rear of the lower end of the seat. backrest, whose second connecting rod is formed by a second fitting attached to a side wall of the seat body, and whose articulated levers are articulated to the two rods at a distance between them, that the headrest is hinged to the lateral terminal region. upper back of the seat body, and that a first end of an actuating lever is articulated away from this joint, lever whose second end is articulated on an extension of an articulated lever which protrudes from the point of articulation of the articulated lever on the second connecting rod.
    By the corresponding articulated quadrilaterals, there is a forced displacement of the backrest following the corresponding actuation by the user, knowing that by coupling the actuating lever to the headrest and articulated quadrilateral, there occurs a forced movement of the operating lever so that the headrest can be adjusted in the two possible positions depending on the setting of the backrest part.
    It is preferably provided that the rear end of the seat portion is hinged to the first fitting, the seat portion being guided and supported longitudinally sliding on a guide portion integral with the seat body.
    By this embodiment, the user can undertake the adjustment of the seat part in both positions simply by soliciting by its weight the seat part and sliding it by the weight of his body which rests on it, knowing that one also also forcibly obtained the displacement of the part of record and the displacement of the headrest in the two positions of use.
    Preferably, it is further provided that the first articulated lever is articulated on the end region before connecting rods, the second articulated lever is articulated on the rear end region of the connecting rods, and the extension is part of the second articulated lever.
    This arrangement is advantageous with respect to the resulting bulk conditions behind the back portion within the seat body, since an embodiment which requires relatively little space is provided.
    It is also provided, in a manner known per se, that the actuators, hinge points and / or articulated elements and actuating levers are respectively arranged in pairs on both sides of the seat body and / or the part of the seat, the backrest and the headrest.
    Preferably, it is further provided that the backrest and the headrest are padded and provided with a covering fabric, the padding and / or the covering fabric extending uninterruptedly on the front side of the backrest and of the head restraint.
    The forced displacement of the elements of the first use position in the second use position and back into the first use position is possible in a simple manner even in the presence of such padding of the file and the head restraint, without the padding and / or the covering fabric wrinkling or crashing in the area of the point of attachment of the head restraint and the backrest.
    An exemplary embodiment of the invention is shown in the drawings and is described in detail below.
    Among the drawings: FIG. 1 represents a seat according to the invention in a first position of use; Figure 2 shows the same seat in a second use position, each in side view and with parts of the seat body partially cut away.
    The seat shown in the drawings consists of a seat body 1, which has on the left of the drawing a portion constituting the rear side of the seat and which forms side walls among which only the rear side wall is shown in the drawings. The front side wall is cut to make visible the kinematics of the set of fittings. A backrest 2 is fixed to adjustable inclination on the seat body 1. In addition, a seat portion 3 is disposed on the seat body 1 with sliding and slightly adjustable inclination. Finally, a headrest 4, which is an extension of the backrest 2, is pivotally attached to the seat body 1. In a first use position, which is shown in FIG. 1, the seat portion 3 is moved to the back of the seat body 1 (to the left in the drawing) and oriented almost horizontally. The drawing shows that the seat portion 3, in this position, is inclined with a slope only slightly downward towards the rear. The backrest 2 is straightened and inclined with a relatively steep slope, and moved by its lower end towards the back of the seat body 1. The headrest 4 is oriented horizontally by being lowered by pivoting backwards, and it covers in this position the edge of the upper rear edge of the seat body 1.
    In the second use position, which is shown in Figure 2, the seat portion 3 is moved forward protruding from the front edge of the seat body 1 and is oriented by being inclined with a slope down slightly towards the back of the seat body 1. The back 2 is slightly inclined and is moved by its lower end towards the front edge of the seat body 1. The headrest 4 is oriented approximately vertically, knowing that it should be noted here that the term "vertically" should not be understood literally, since, as shown in Figure 2, the headrest 4 is slightly inclined towards the back to the vertical.
    According to the invention, the headrest 4 is coupled to the backrest 2 via an actuator 5 by means of which the headrest 4, when the backrest 2 is in the first position of use, is pivoted forcibly in the horizontal position directed towards the bitter, and by means of which the headrest 4, when the backrest 2 is in the second position of use, is pivotally raised forcibly in the second position use.
    In the exemplary embodiment, the backrest 2 is connected to the seat body 1 via an articulated quadrilateral. The first connecting rod 6 is formed by brackets 6 fixed on the side and at the rear of the lower end of the backrest 2 (only one fitting is shown in the drawings, but the fittings are arranged in pairs on both sides). ). The second link is formed by a second bracket 7 fixed to a side wall of the seat body 1. The femire 7 shown in the drawings is fixed on the side cheek of the seat body 1 which is cut in the drawings. The articulated levers 8, 9 of the articulated quadrilateral are articulated to the two rods at a distance from each other. The hinge points are designated by numerals 10, 11, 12, 13. The headrest 4 is hinged to the upper lateral end region of the back of the seat body 1 (hinge point 14). A tab 15 is fixed for this purpose on the seat body, a lug of which one end has or constitutes the hinge 14. A first end of an actuating lever 16 is articulated at a distance from this hinge 14 on the support. head 4, further from the upper end of the backrest 2, the second end of the lever 16 being articulated on an extension 17 of the articulated lever 9 (hinge point 18). The upper articulation point on the headrest 4 is designated 19. The extension 17 protrudes from the articulation point 12 of the articulated lever 9 to the second connecting rod 7. The rear end of the seat portion 3 is in further articulated on the first fitting 6 (pivot point 20), the seat portion 3 being further guided and supported longitudinally sliding on a guide portion 21 integral with the seat body, namely a guide rail in the exemplary embodiment; for this purpose, a corresponding guide element 22, which engages a guide portion in the guide portion 21, projects from below the seat portion 3.
    The first articulated lever 8 is articulated on the front end region of the respective links 6, 7, while the second articulated lever 9 is articulated on the rear end region of these rods. The extension 17 is part of the second articulated lever 9.
    As illustrated in the figures, the backrest 2 and the headrest 4 are padded (padding 23) and optionally provided with a covering fabric. This padding 23 extends uninterruptedly on the front side of the backrest 2 and on the front side of the headrest 4. When the seat is moved from the position according to Figure 1 in the position according to Figure 2, it deformations or buckles do not form in the region of the connection of the padding between the backrest 2 and the headrest 4. Similarly, during the return movement of the position according to FIG. 2 in the position according to FIG. there is no crushing or other deformation of the padding in the region of the connection point between the backrest 2 and the headrest 4.
    The adjustment of the seat according to the exemplary embodiment is carried out in such a way that the user, who sits on the padding of the seat part 3, moves the seat part 3 of the position by a movement of his body. FIG. 1 in the position according to FIG. 2. The backrest portion 2 is then driven together and a corresponding displacement of the articulated quadrilateral is caused, which itself has the consequence that the operating lever 16 also forces a pivoting of the seat. headrest 4 in the upright position. If the seat is to be moved back from the position according to Figure 2 in the position according to Figure 1, the user then pushes by the force of his body the seat portion 3 of the position according to Figure 2 in the position according to Figure 1. Due to the articulated quadrilateral, there is then a corresponding return movement of the backrest 2 and, by the actuating lever 16, a return movement of the headrest 4, until the position according to Figure 1 is reached.
    The invention is not limited to the exemplary embodiment, but may experience many variations in the disclosure resulting from the present disclosure.
    All new individual features and combinations of features disclosed in the description and / or drawings are considered part of the invention.
