    Short designation: Seating furniture comprising a frame, a seat on which a user can sit, and at least one footrest connected to the frame
    Description
    The present invention relates to a seating furniture comprising a frame, a seat on which a user can sit, and at least one footrest connected to the frame for supporting both feet of a user sitting on the seating furniture.
    Such seating furniture is known in various forms and such seating furniture is used as chairs, for example, in schools. Such school buoys are often used for work in conjunction with a table with a standard table height.
    Children who are relatively small and have a relatively short lower leg length can use the footrest of the seating furniture to adopt an ergonomically favorable body position, for example to work at the table.
    Children grow relatively quickly, which means that even within a school year the proportions can change, which means that the favorable ergonomic posture at the beginning of the school year can become less favorable during the school year. In schools it can then be decided during an inspection to give the child a different seat with a different seat height and / or different footrest height, so that an ergonomically favorable posture can again be provided during working. For this purpose, schools should include relatively large stocks of spare chairs in order to be able to offer each child a chair suitable for that child from an ergonomic perspective. These spare chairs are designed differently so that they are suitable for children of different heights.
    It is an object of the present invention to provide an improved seating furniture.
    This object is achieved with a seating furniture as defined in claim 1.
    The seating furniture comprises a frame, a seat on which a user, for example a child, can sit, and at least one footrest connected to the frame for supporting both feet of a
    2018/5005
    BE2018 / 5005 user seated on the seat. The seat of the seating furniture is movable after unlocking and after moving the seat, the seat can be locked in at least a number of predetermined sitting positions, by moving the seat from a first predetermined sitting position to a second predetermined sitting position or vice versa. height between the seat and the ground can be varied, and the height measured from the ground for supporting the feet can be varied.
    From an ergonomic point of view, this adjustable seating furniture provides the ideal situation for (fast) growing children, because a single chair can be adapted to a height change of a child. A single chair can also be used between different children of different heights. The seating furniture can be adjusted to the height of the child to adopt an ideal working position, especially for sitting while working at a table. The seat of the seating furniture can assume different sitting positions, whereby in each sitting position the height for supporting the feet measured from the ground is different and the height of the seat measured from the ground is different. In conjunction with these heights measured from the ground, the distances from the seat and the footrest to a standard table can be set at a fixed working height of, for example, 76 cm, so that an optimal working posture of a user can be guaranteed.
    The seating furniture further comprises a relatively simple construction, which makes it inexpensive to manufacture. In this way it is financially easier for schools to purchase such height-adjustable seating furniture so that the children can work at a table in an individually determined optimal working position.
    With the seating furniture, you can adjust both the seat height and the footrest height in a single operation.
    Also, due to the adjustability of the seating furniture, only a minimum number of types of school chairs or only a single type of school chair need to be ordered by, for example, a primary school for all children or at least a large part of all children from the different classes of a primary school. In addition, fewer spare school chairs need to be in stock, because, for example, at least two sizes that are different in size cannot be adjusted
    2018/5005
    BE2018 / 5005 3 school chairs in stock can be replaced by a single size-adjustable school chair (seating furniture) as described in this document.
    In this document, seating furniture is preferably intended to mean seating for one person, such as, for example, a chair or a stool. Preferably it is. seating furniture a high chair or a child's stool.
    Preferably, the frame comprises at least two uprights between which the at least one footrest extends, so that a user can easily place both feet side by side on the footrest to assume an optimal working posture. The uprights at least partially enclose an acute angle with the substrate and / or extend at least partially perpendicular to the substrate. Uprights also mean the legs of an underframe such as an underframe comprising a three, four or five legs. The acute angle that the uprights / legs enclose with the ground is preferably at least 30 degrees, so that different footrests at different heights can be provided between different uprights / legs.
    In one aspect of the seating furniture, the height between the seat and the surface can be varied between 40-60 cm, preferably the predetermined seating positions correspond to at least part of the codes A1-G7 according to the European height standard NEN-EN 1729. The NEN standard 1729 assumes seven dimensions for both tables and seating furniture such as frolics, indicated by a code and a color.
    A further aspect of the seating furniture is that the number of predetermined sitting positions comprises at least three different sitting positions, preferably at least three different sitting positions corresponding to three different seat heights.
    The seating furniture can further be provided with markings, such as, for example, the colors according to the European height standard NEN-EN 1729 for a user, which markings correspond to the seating positions, so that the seat can easily be moved by a user to a seating position suitable for the user. If the users are children, the seating furniture preferably includes a child-resistant unlocking and locking mechanism before the seat can be moved between the different seating positions.
    The frame may further include a central support to which the seat is connected, thereby moving the seat between two
    2018/5005
    BE2018 / 5005 4 different seating positions includes a rotation of the seat through a predetermined angle.
    Such a seating furniture can comprise different footrests at different footrest height measured from the ground. The seating may be provided with at least three uprights (legs) and at least two footrests arranged at different heights of the ground, comprising a first footrest extending between two of the three uprights for the user in the first sitting position and a second between two others of the three uprights extending footrest for the user in the second sitting position. After or during the unlocking of the seat, the seat can be moved up or down and rotated through a predetermined angle, for example a quarter turn (90 degrees). By moving up or down, the seat height of the seating furniture can be adjusted and by rotating a footrest can be selected at a different height. Each seating position can have a fixed combination of seat height and table height. The seat height is the distance between the seat and the footrest, and the table height is the distance between the footrest and a table at a standard height of, for example, 76 centimeters. It is also possible that the seating furniture includes one footrest, in which varying the height measured from the ground for supporting the feet comprises only two options, i.e. placing the two feet on the ground or placing the two feet. on the footrest at a certain height from the surface.
    In another aspect of the seating furniture, the height of the footrest relative to the ground is adjusted simultaneously when the seat is moved from a first sitting position to a second sitting position. In this way, the height of the footrest is automatically adjusted and it is impossible to choose a non-predetermined combination of seat height and footrest height, which will increase the ease of use for the user.
    For moving the seat of the seating furniture between a number of seating positions, the frame can be provided with a number of frame parts that can be moved telescopically with respect to each other, wherein at least one of the frame parts moves the seat to one another is connected. It is also possible that the seat is slidably connected to the frame for moving the seat between a number of seating positions.

    BE2018 / 5005 7 positioning. It is also possible that the seat 8 (the shell 9 with the coupling piece 7) is releasably connected to the central support 15 after unlocking.
    The tub 8 with the seat 9 is movable after unlocking between a number of predetermined seating positions. Moving the shell 8 with the seat 9 between at least two different seating positions involves a rotation of the shell 8 relative to the chassis 5 of the chair 1 by a predetermined angle in the direction indicated by arrow P2. In the exemplary embodiment shown, the angle through which the chassis 5 and the shell 8 are rotated relative to each other to bring the chair 1 into a new seating position is 90 degrees. After the rotary movement of the fairing 8 relative to the chassis 5 by the user, the fairing 8 is moved vertically downwards in an opposite direction indicated by arrow P1 for locking the coupling piece 7 which is connected to the fairing 8 in the tubular support 15 of the frame 3. In this way, the tub 8 with the seat 9 can be moved into a number of predetermined sitting positions and then locked. As a result of this displacement of the cockpit 8 from a first predetermined sitting position to a second predetermined sitting position or vice versa, the height h1a, h1b, h1c, h1d is between the seat 9 and the chassis 5 and thus the height between the seat 9 and the ground 75. vary, as well as vary the height h2a, h2b, h2c, h2d measured from the ground to support both of a user's feet.
    Figures 2a-2d show the different codes C3, D4, E5 and F6 corresponding to the dimensions shown in the above table. These dimensions represent the predetermined distances between the seat 9 and the footrest 28, 29, 30 as well as the distances between the table 50 and the footrest 28, 29, 30.
    The caps 20-23 comprise a common color (marking) in pairs, which color corresponds to the color and code in the table above. Part of the surface of each cap 20-23 facing a first footrest 28-30 is provided with a first color and another part of the surface of each cap 20-23 facing a second footrest 2830 of a different color. For example, cap 20 is marked blue (F6) on the side where no footrest is attached and marked green (E5) on the footrest side, and cap 23 is marked blue (F6) on the side where no footrest is attached. the side of footrest 29 is red
    2018/5005
    BE2018 / 5005 8 marked. In this way, a user, for example a child himself or else a teacher, can easily adapt the chair to the child's height so that the child can work on the table 50 in an optimal working position from an ergonomic perspective. The height of the table 50 is fixed and is for example 76 cm.
    The markings can also be applied to other parts of the chair 1, such as for instance on the footrests 28, 29, 30 which can be provided with individual colors from the table above corresponding to that footrest 28, 29, 30.
    Figures 3a, b show another embodiment of the seating furniture. The seating is a chair 101, more particularly a school chair. The chair 101 comprises a frame 103 and a seat shell 108. The seat shell 108 is provided with a seat 109 on which a user can sit and a backrest 110. Furthermore, the chair 101 comprises a footrest 128 hingedly connected to the frame 103 for support of both feet of a user sitting on chair 101.
    Like the embodiment of the chair 1 shown in Figures 1a, b and 2a-d, the seat 109 of the chair 101 shown in Figures 3a, b is movable after unlocking and after moving the seat 109, the seat 109 is in a number of predetermined sitting positions, whereby by moving the seat 109 from a first predetermined sitting position to a second predetermined sitting position or vice versa, the height between the seat 109 and the ground can be varied, as well as the height h measured from the ground for the support of the feet is variable.
    Frame 103 includes a support frame 124 and at least two uprights 111, 112 between which the at least one footrest 128 extends. The uprights 111, 112 at least partly enclose an acute (virtual) angle with the ground and partly extend horizontally. In the base of the chair 1, the uprights 111, 112 are directly connected to two horizontally extending support tubes 126, 127 of the support frame 124. By means of the horizontally extending end parts of the uprights 111, 112 and the horizontally extending support tubes 126, 127 the support chair 101 on a surface using support caps 120, 121, 122, 123.
    The footrest 128 is with the aid of two lath-shaped connecting elements 142 via hinge connections 140 (only one
    2018/5005
    BE2018 / 5005 hinge connection is shown in Figures 3a, b) connected to the support tubes 126, 127. The seat 109 of the fairing 108 is directly connected to the two lath-shaped connecting elements 142 of the footrest 128 by means of two connecting elements 144. Each connecting element 144 is hinged at one end thereof by means of a hinge connection 146 to the seat 109 and one of the two support tubes 126, 127.
    The chair 101 has the special feature that moving the seat 109 from a first sitting position to a second sitting position simultaneously adjusts the height h of the footrest 128 relative to the ground. This is provided using the hinge joints 140, 146 as well as the direct connection through the connecting elements 144 between the seat 109 and the footrest 128. In this way, the footrest 128 is automatically adjusted together with a displacement of the seat 109.
    The uprights 111, 112 of the frame are provided with a number of frame parts 111a, 111b, 112a, 112b which can be moved telescopically with respect to each other. The frame parts 111a, 112a are directly connected to the seat 109 and the backrest 110. After unlocking a locking mechanism (not shown), the frame parts 111a, 112a can be moved relative to the frame parts 111b, 112b by telescoping them in and out slide. Due to this telescopic displacement, the seat 109 can be moved between a number of sitting positions, the seat 109 being lockable in one of the predetermined sitting positions by means of the locking mechanism. As mentioned above, the height h of the footrest has also changed.
    It is also possible that the seat is provided with a sliding mechanism (not shown) so that after unlocking it is slidable along the uprights 111, 122 of the frame 103 for moving the seat between a number of seating positions in which the seat can be locked. The seat can then be connected in the same manner to the footrest 128 as shown in Figures 3a and 3b, so that the height h is adjusted simultaneously with the movement of the seat.
    In the chair 101 shown in Figures 3a, b, the number of predetermined seating positions may be greater than in the chair 1 shown in Figures 1, 2a-d. For example, it is possible that the locking mechanism is provided with a click mechanism so that the user knows when the seat 109 (and the fairing 108) are in a
    2018/5005
    BE2018 / 5005 predetermined sitting position. It is also possible that the chair 101 can be locked in any position, wherein at least two predetermined positions can be visually determined by a user by means of markings.
