Definitions
- the present invention relates to a self-adjusting backup device, which has an automatic means of adapting the position for the user's comfort. It is applicable to all types of seats: chairs, sofas, armchairs, wheelchairs, car seats, etc. and even as an independent element to place on the floor.
- document ES2118081T3 refers to a chair comprising a seat and back joined together, characterized in that the backrest has a certain movement when it is related to two horizontal axes, one on which it pivots and another that limits the movement thereof.
- Document US2005035636A1 discloses a chair of the type comprising seat and back joined together, which is self-adjusting characterized in that it comprises a backrest formed by a support plate of the back, supported by a horizontal axis articulation arranged on a support being said articulation at a certain distance from the base of the backrest, preferably in an area at an average height of the backrest and having a cushioned turning spring and limited by a turning stop system and in whose rest position the plate is in approximately vertical.
- the plate, the support and the articulation are included in a semi-rigid shell.
- Patent W09427472A1 discloses a chair, comprising seat and back joined together characterized in that it comprises a backrest / support plate of the back, supported by a hinge of horizontal axis.
- Document ES2255466A1 refers to a self-adjusting chair characterized in that it comprises a running part that serves as a backrest and seat and that is supported by a joint.
- Document DE20113075U1 refers to a chair, comprising seat and back, characterized in that the backrest comprises an arm with two axes, a lower one that relates it to the seat and another upper one that regulates the position of the plate on which the chair rests. user.
- the invention relates to a self-adjusting backrest device that protects the lumbar and relaxes the pressure on the buttocks.
- the backup is self-adjusting which implies that no control or command is needed on it.
- the mentioned device complements a seating surface in such a way that said seating surface is previously existing and what is the object of the present adds a support or improvement to the existing one.
- the self-adjusting backrest assembly comprises a movable plate on which the user rests, said plate being pivoted on a horizontal axis passing through a first set of bushings attached to the plate, said axis being associated with a second set of bushings attached to a support which can be the backrest of the chair or chair where the self-adjusting backrest is going to be used, in which case we will call it pre-existing backing, or it will be a fixed backrest that is part of the device, in which case we will call it backing of the device.
- At least one of the sets of bushings is adjustable in height and thus, the variation of the height of the first set of bushings will vary the relative point where the iron pivots by altering the lever while the variation of the height of the second set of bushings will alter the height at which the iron is located.
- the backrest of the device can have different dimensions depending, among other things, on the surface on which it must rest.
- REPLACEMENT SHEET (RULE 26) The iron has an initial position, in the absence of forces applied by the user or at his will, and a stroke of balaceo that can be bounded by a maximum and a minimum position.
- the ideal initial or resting position is preferably close to the vertical, although this may vary depending on the inclination of the pre-existing backrest or the support on which the backrest of the device rests.
- This rest position is obtained thanks to the action of a turning spring in whose resting position the iron is in an approximately vertical position, this turning spring being able to be cushioned for the comfort of the user. While nobody uses it, the iron is in the rest position, this position being forced by the turning spring that is able to overcome the weight of the iron and take it to the initial position and keep it in that position, but allowing it to yield to the pressure of the user when sitting without the expulsion force being perceived by the user.
- the path of the plate can have a stop.
- the moving plate assembly, first and second set of bushings, shaft and support will be included in a semi-rigid housing so that the user will not observe these mechanical elements and the risk of gripping will be reduced.
- the lower part of the plate can incorporate an elastic element that closes the space between the plate and the seating surface, reducing the risk of impingement of an object or part of the user's body that is inserted there.
- This elastic element will generally join the seat surface to the plate and may be a rubber fabric which, in addition, can contribute to the return of the plate to the vertical position, thereby obtaining two advantages with a single element.
- REPLACEMENT SHEET (RULE 26)
- the assembly comprising the plate, the first and second set of bushings, the shaft and the support is suitable to be associated with a chair, armchair or sofa among others among which can be included car seats, of greater complexity.
- the self-adjusting backup device Once the self-adjusting backup device is installed, the user will sit on an approximately horizontal and existing seat surface and support the back on the self-adjusting backrest device.
- the height of the shaft will be adjustable and will be disposed between 12 and 33 cm on the user's seating surface, and preferably between 18 and 27 cm.
- the self-adjusting backrest can incorporate different accessory elements to be fixed and prevent it from moving before the weight of the user.
- the device in a possible execution, can incorporate suitable pegs for digging into soft ground such as dirt or sand. In another possible execution, it can incorporate non-slip feet to fix it on smooth surfaces.
- the device can incorporate a skirt whose function will be that the user fixes the support by its own weight which will be useful when, for example, the user wants to read in bed and lean on the device.
- the seating device may have armrests or any other element without altering the nature of the invention.
- the plate may have curvature, padding, flexibility, rigidity or any other measure to increase user comfort.
- the material will be wood, plywood, plastic, metal, cloth, wicker, or any other.
- REPLACEMENT SHEET (RULE 26)
- the iron can be separated from the shaft to facilitate the tasks of cleaning, repair or regulation among others.
- FIGURE 1 shows the invention in an execution mode in which the backrest of the chair in which the device is used is used as a fixed backrest and thus we find the moving plate (1), the first set of bushings (2) attached to the moving plate, the shaft (3) and the second set of bushings (4) attached to the support, in this case a pre-existing backrest (5).
- FIGURE 2 shows, in outline, an adjustable backrest device that does incorporate a fixed backrest in this case prepared to rest on the backrest of an armchair and thus we find the moving plate (1), the first set of bushings (2) the shaft (3) the second set of bushings (4) and the backrest of the device (6).
- FIGURE 3 shows an execution in which the backrest of the device (6), which has a triangular section shape, incorporates pegs (7) to anchor the backrest to a soft and pierceable soil such as earth or sand.
- FIGURE 4 shows an execution in which the backrest of the device (6) incorporates bases (8) suitable for fixing the device on a smooth ground.
- FIGURE 5 shows an execution in which the backrest of the device incorporates a skirt (9) between the seat surface (10), in this case the floor, and the user being, thus, the user, with his own weight, prevents the movement of the device.
- the self-adjusting backrest that is complemented by a seating surface comprises:
- a turning spring holds the iron in approximately vertical position when it is at rest, that is, when there is no external force acting on it.
- the device has been supported on a seat surface (10) such as a bed or the floor.
- the first set of bushings (2) which is adjustable in height is attached to the mobile plate. By varying the relative height of the first set of bushings, and therefore the axis, with respect to the plate, the point on which the plate is pivoted is modified by modifying the lever that makes the plate.
- REPLACEMENT SHEET (RULE 26) To the shaft (3) is also associated the second set of bushings (4) that are attached to the backrest of the device (6).
- the second set of bushings is also adjustable in height and, by varying its height, the height of the plate and the axle in relation to the seating surface is modified.
- the axis on which the plate is pivoted is at a height of 23 cm, with a height of between 12 and 33 cm from the seating surface being normal, and preferably between 18 and 27 cm.
- the action of the first and second set of bushings and the horizontal axis that relates them allows the movable plate to pivot on the backrest of the device in such a way that the greater the force exerted on the upper part of the moving plate, the action on the lumbar and relaxes the pressure on the buttocks to which it elevates.
- the self-adjusting backing device in order to prevent the self-adjusting backing device from being displaced by the horizontal force exerted by the user when leaning on it, it comprises a skirt in the manner of a strut on which the user feels, with his weight, prevents the assembly from moving.
