DESCRIPTION

Technique Field

The present invention refers to a height adjustable seat with a trunk support system that induces trunk verticality for users who manipulate keys or buttons with their hands and pedals or levers with their feet and a neuro-inducing posture device for vehicles or semovientes in those who travel sitting or astride whose purposes are to provide an improvement of the postural system as well as reduction of the user's body fatigue.

Specifically, it should be noted that said neuro-posture-inducing device can be applied to the seats or be a seat of any vehicle or semi-wind, land, naval or air vehicle in which it is seated or astride but preferably arranged in bicycles and / or motorcycles.

State of the prior art

The prior art prior to these inventions would be defined by the following utility model records:

- U 200700274: In this utility model, the resting device for surgeons that it protects has as its main purpose to improve the posture of surgeons, in a fundamentally static situation, when they are operating. Specifically, the problem to be solved is excessive tiredness and aggression to the musculoskeletal system of both the back and the lower extremities of surgeons who, sometimes, when they have to intervene in parts of the patient with difficult access, are seen forced to adopt forced postures that leave the trunk as a cantilever beam, semi-recessed by the coccyx.

For this, the device seat has a surface with a relief designed to place the buttocks of the seated person in a convenient place for proper operation.

of the biomechanical system that the trunk and arms form in such a way that it induces the user to keep the legs open and the feet in contact with the ground, allowing a great mobility of the trunk but fixing it strongly through the anchoring effect that the concavities exert of the soul of the seat on the ischia.

In addition, the support offered by this device to the user is based, not only on the seat but also on the trunk and elbows of the surgeon in such a way that they can hold the surgeon's body tilted towards the patient.

- U201100343: This utility model protects an esthetic seat that incorporates a ischiatic support which helps to position the seat of the seated so that it can rest on the small backrest with the back in a symmetrical way, and the spine well centered on said backrest . That is, this support serves only as a spatial reference.

- U201000377: This utility model protects a seat for pluripostural tasks that includes some subisquibotic gaps whose role is purely biomechanical since they only collaborate to position the trunk of the seated so that it can rest on the very narrow backrest with the back symmetrically , and the spine well centered on said poor support. That is, once mbs, said gaps serve only as a spatial reference.

As will be seen below, the main purpose of the height-adjustable seat with a gluteal support system that induces trunk verticality according to the invention is to cause a seated posture with a trunk-fbmur angle much greater than 90 °, which is requested by contact the sacro-coxigea region of the user and that has a variable hardness in the contact surface with the buttocks of the seated one, such that the ischiatic tuberosities of this fall significantly in the vertical of the softer area of the seat. Well, although all the objects protected through these utility models refer to static seats, none of them achieves the purpose pursued by the present invention, since the users of the object of this invention start from different positions from those of the users of the aforementioned utility models and also because in said utility models it is not specified exactly where the ischiatic tuberosities should be located.

In addition, the benches and seats that are on the market intended for the user who manipulates keys or buttons with their hands and pedals or levers with their feet do not offer these three conditions at the same time: allow the sedentary a good support of the sacral region, have less hardness in the vertical of the ischidic tuberosities and facilitate an inclination of the thighs forward.

On the other hand, there is currently no known existence in the market or in the state of the art of a neuro-inducing posture device such as the one proposed here for vehicles in which you are sitting or astride that are more comfortable and produce Less body fatigue

The closest existing in the state of the art are seats that have been designed, in relation to the user's postural health, taking into account their specific anatomical and biometrical conditions to minimize the transmission of the vibrations that the vehicle communicates to it. to that user.

Also, in the state of the art you can find clothing for users of two-wheelers that have padding on the buttocks but the improvement in comfort achieved through this padding is based solely on a biomechanical concept consisting of elasticity and hardness of the element that touches the user's body so that it! said user has a better distribution of pressures and perceives a softer contact between the buttocks and the seat.

These ergondmic considerations take into account the frequency of the user's body segments and are useful for determining the frequency of the elements of the vehicle in contact with the person who occupies it, so that there is no resonance between the object and the person or their body segments.

Some of the existing seats in the market have a lot of ergondmic mdrito, an excellent adaptation to the anatomy of the users that move in them and a not negligible beauty that can get to print a stamp to the brand that produces them. But none of the existing models on the market have a device that is specifically intended to request the user's postural system regardless of the biomechanical effect that the seat produces in the posture that it induces.

The proposed neuro-inducing posture device is not intended for users who are at rest, but for those who travel in a vehicle or semoviente, and its most important novelty is that it is based on the capacity of the fine postural system of the person to induce the body of this a posture that, with the use of the device as a seat directly or on or integrated in any seat model, produces less fatigue during the trip than the one that would produce the same seat model that lacked the device Neuro-inducer of healthy posture. Such improvements are not achieved through biomechanical elements such as those existing in e! state of the technique but by means of neuro-inducing posture elements, and postural improvement, as well as the reduction of fatigue in its users, is greater than in existing devices in the state of the art.

Explanation of the invention

First, it should be noted that this application claims priority of the Esparto utility model! with application number U 201301114 filed on December 18, 2013.

In this utility model, a height-adjustable seat is protected with a gluteal support system that induces trunk verticality that allows postural improvement and reduces fatigue for those users who, from a sitting posture, manipulate keys or buttons with their hands and pedals. or levers with the feet. For this, it is essential that the ischiatic tuberosities have a perfect positioning which is achieved with a lower hardness of the upholstery of the adjustable seat in the vertical of these bones or by piercing the hard part of the seat in this area, thus defining the essential element of the invention of the mentioned utility model whose main effect is biomechanical.

This essential element has been proven that they can also be applied to private seats for vehicles or semovientes in which you travel sitting or astride producing postural improvements in users as well as a reduction in body fatigue. Also, in these last cases the effect produced by this essential element is no longer only biomechanical but also neuronal.

Therefore, this description will detail two inventions that are encompassed under this same principle or essential element. On the one hand, in the case of static users, a adjustable seat for certain positions is protected. On the other, in

5

35

In the case of dynamic users, a device is protected for vehicles or semovientes in which they travel sitting or astride.

In the first case it is a seat for users who, from a sitting posture, manipulate keys or buttons with their hands and pedals or levers with their feet, although the object to be protected can also serve for a plurality of sedentary activities or for postural learning of sedentation by providing a multiplicity of forms of support that adapt to various pathologies of the musculoskeletal system.

Specifically, the object to be protected is a height adjustable seat whose contact area with the user's thighs and buttocks shows at least a part intended to support the buttocks that has a lower hardness in the area corresponding to the vertical of the ischiatic tuberosities of the seated.

Preferably, the height-adjustable seat has three parts intended to support respectively the thighs, the buttocks and the sacral-coxigea region of the seated person. The parts intended so that the thighs and buttocks can be supported have an inclination with a fall forward, respectively, to allow an obtuse angle between legs and trunk, and to ensure contact with the sacral-iliac area of the seated.

In a preferred embodiment, said three parts are made of a hard material and covered with a soft material upholstered with a fabric that can be of various materials and which has to have a roughness that prevents the easy sliding of the buttocks and thighs of the seated .

The specific characteristics of the seat that contribute to induce a posture of healthy verticality in the trunk of the user that manipulates keys or buttons with the hands and pedals or levers with the feet, are the following three: a) support of the sacrum and coccyx, b) positioning of the ischiatic tuberosities, and c) wide coxo-femoral angle. Contact with the sacral-coxigenic region causes a perception of a support point of the dseum system in postural captors; postural captors also perceive the two support points of the ischiatic tuberosities; These three non-aligned points make up a support triangle that, as a tripod, is perceived by the postural system as a stable base of trunk support, which induces you to relax the postural musculature not necessary for trunk stability. The positioning of the ischiatic tuberosities plays an important role in establishing the aforementioned support tripod, and it is achieved

5

35

with a lower hardness of upholstery in the vertical of these bones, or even piercing the hard part of the seat in this area, with both resources or with any other device that achieves the goal of seating the buttocks in a position determined by the vertical of the ischhetic tuberosities. The wide coxo-femoral angle that causes the seat to protect induces the psoas muscle to exert a tension that maintains the physiological curves of the dorsal spine of the seated since, by joining the vertebrae that go from T12 to L5 with the trochanter of the femur, The more open the Coxo-Femoral Angle, the more force is exerted on these vertebrae in the sense of maintaining the physiological curves of the back.

The seat with a gluteus support system that induces trunk verticality can be adjustable in height by means of one or more pistons, preferably gas and lever operated. This piston can be supported by a base of at least one arm, with or without wheels, or by another type of support that ensures the solidity of the seat.

The height-adjustable seat with a trunk vertical inducing gluteus support system can incorporate in its back a backrest connected to the seat by a metal plate that allows to vary the distance between the vertical of the piston and this backrest that can be placed in one or more copies attached to the metal plate by a rosea system that exerts pressure between the support plate and the dorsal support piece and that allows the rotation of this around a horizontal axis located at the level of half the height of this piece.

This contact piece with the seated back can be upholstered with a layer of soft material. The covering of this upholstery can be made of a material that allows pads that modify the original relief of the backrest to be attached to facilitate adaptation of the seat back.

Once the first object of the invention has been explained, the second object of the invention will be explained.

The neuro-inducing posture device according to the invention can be installed in any vehicle or semoviente in which you travel sitting with your thighs on the seat and your legs in front of 61, or astride, with a piema on each side of the seat, although preferably it will be installed on bicycles, motorcycles or semovientes.

This neuro-posture-inducing device can be used directly as a seat or placed on the seat of the vehicle externally or hidden inside the seat, either because the seat has incorporated it during its manufacturing process or because the user has incorporated later.

Said posture neuro-inducing device may have any shape but, preferably, it has a shape similar to that of a vehicle seat or vehicle seat on or in which it has to be installed and comprises a rest area, which may be filled with some material, prepared so that the user can arrange his buttocks on it, in which the area defined by the vertical projections of the user's ischiatic tuberosities has a lower hardness or a decrease in the density of the material of that the aforementioned rest area is made or filled. Preferably, this decrease in the density of the material is obtained through at least one hole that includes the vertical projections of the user's ischiatic tuberosities. Said hole will be hollow although it could be filled with a softer material than the one used to fill the rest area and preferably have an ovoid shape.

In this way, the pressure exerted by the buttocks on the rest area and the seat of the vehicle in the area of maximum pressure that is the vertical of the ischium, causes that rest area to sink and the part of the seat defined by the projections From the verticals of the user's ischiatic tuberosities, which has a lower hardness, mbs is created creating a kind of crater that collects the roundness of the tuberosities through the gluteus musculature. It has been proven that postural captors in this area of the tuberosities play a role in the balance of the trunk that is similar to the role that the captors of the soles of the feet play in the balance of a standing subject. That is why we can say that the trunk is "planted" on the ischia and that these are collected by that weak crater that its pressure creates in the seat thanks to the neuroinductive device.

Through the action of this neuro-inducing posture device according to the invention, the fine postural system captors perceive a slight embedment of the user's hamstring-gluteal-clothing system in the seat. Without the device, postural captors perceive a support - without embedment - of the user's ischion-glute-clothing system on the seat. In this case (support) the vibration that transmits the seat to the user could make the buttocks slide if the friction of the user's clothes-seat was negligible, since the grip of the

5

35

The body of the user to the seat is only secured by friction clothing-seat. In the case of the small crater created by the neuro-inducing posture device, the sliding produced by the vibration is slowed down by the effect of the weak embossing of the ischium induced by the neuro-inducing posture device, but the biomechanical effect is not the It produces the improvement of the user's fatigue, but the postural effect: the reorganization of the work of the muscle chains that the postural neuronal system performs thanks to this neuro-inducing device of healthy posture. The postural system governs the biomechanics, through a neuronal mechanism, and just as posturologists can correct imbalances of the body using soft templates of the thin thickness of 1mm, the smallness of this device-induced crbter is sufficient for the postural system to correct muscular activity in the sense of not working the muscle chains that, without the neuro-inducing posture device, would be active in anticipation of a possible dangerous sliding of the user's buttocks.

Although the most relevant novelty presented by this neuro-inducing posture device according to the invention is its effect on the postural system, the biomechanical effect of subischial craters also induces an improvement in user comfort due to the better distribution of pressures it facilitates. , so that the points that reach the maximum pressure in the subischial area of the buttocks will reach a lower pressure with the use of the device, while other points in their environment will absorb higher pressures, all due to a better distribution of pressures. Reducing the value of maximum pressures is an indisputable improvement.

Another improvement that represents the posture neuro-inducing device according to the invention lies in the fact that users, when they make long trips, unconsciously usually support the trunk alternately in one or another gluteus and if the seat of the vehicle in which it is located the user has a posture-inducing neuro-device according to the invention or the posture-inducing device itself directly seats, the pressure is relieved on one side and increases on the other and in these circumstances the benefit of a better Pressure sharing becomes even more evident.

The neuro-inducing posture device according to the invention may comprise a resting area containing a filling material, preferably of the elastic type and uniformly arranged throughout this resting area, which makes the user's posture even more comfortable and healthy.

One of the design possibilities of this neuro-posture-inducing device that directly functions as a seat or that is applied to motorcycle, bicycle, as well as land, naval or air vehicles, tractors and industrial vehicles or seats for semovientes in which one travels seated or astride, in which the rest area contains filling material, is based on a decrease in the density of the filling material of the seat in the area or zones of the same that are located in the vertical of Traveler's hamstrings.

It should be noted that this posture neuro-inducing device can also be arranged in the glute part of the interior of sports briefs used by drivers of this type of vehicle, preferably cyclists and motorcyclists and that in a preferred embodiment the area may also contain filler material, preferably of the elist type.
