Definitions

  • the present invention relates to an ergonomic seat for vehicles and similar.
  • the present invention relates to an ergonomic seat for high-performance vehicles, to which the following description refers purely by way of example .
  • seats have been designed which are fitted internally with a number of air chambers, which are inflated and deflated by an electronic central control unit to adapt the stiffness and shape of the seat as closely as possible to the driver's body.
  • an ergonomic seat comprising a supporting frame, and at least one support cushion fixed to the supporting frame to support the user sitting on the seat; said ergonomic seat being characterized in that said support cushion comprises at least one inner bag filled with a gelatinous material of predetermined viscosity and hardness .
  • Figure 1 shows a view in perspective, with parts removed for clarity, of an ergonomic seat for vehicles and similar in accordance with the teachings of the present invention
  • Figure 2 shows a larger-scale section of a cushion of the ergonomic seat in Figure 1.
  • Ergonomic seat 1 comprises a supporting frame 2 preferably, though not necessarily, made of metal and/or plastic materials; one or more support cushions 3 appropriately arranged and fixed to frame 2 to support the user sitting on the seat; and an outer covering 4 preferably, though not necessarily, of leather and/or fine fabrics .
  • support cushions 3 are shaped according to their location on the seat, and at least one comprises a closed outer case 5 of appropriate shape, and one or more inner bags 6 filled with a gelatinous material, i.e.
  • gel a colloidal substance of gelatinous consistency, commonly known as "gel” , comprising solid particles uniformly dispersed in a liquid solvent, in which the solid particles do not give rise to individual molecular aggregates, but instead form a single semirigid mass defined by an irregular lattice extending to the full available volume and englobing the liquid solvent .
  • bags 6 are filled with a "polyurethane gel", which, by virtue of its chemical and physical characteristics, adapts perfectly to the shape of the user's body, and distributes pressure evenly over all the parts of the body resting on bag 6.
  • ergonomic seat 1 comprises a number of support cushions 3 , which, depending on their location on the seat, comprise one or more bags 6, each filled with a gelatinous material whose viscosity and hardness depend on the parts of the body supported.
  • the bags 6 inside the same support cushion 3 may communicate directly with one another, so that the gelatinous material flows freely from one bag 6 to another to achieve the best instantaneous distribution inside support cushion 3, depending on the position assumed by the user's body.
  • ergonomic seat 1 comprises at least one buttock support cushion 3a, at least one lumbar support cushion 3b, at least two pelvic support cushions 3c, at least two pelvic girdle support cushions 3d, and at least one thigh support cushion 3e, each of which, depending on its location on the seat, has one or more bags 6, each filled with a gelatinous material of a viscosity and hardness depending on the parts of the body supported.
  • the buttock support cushion 3a supports the user's buttocks, and has a number of bags 6 (four in the example shown) , which are arranged side by side in pairs, communicate directly with one another, and are filled with a gelatinous material of such viscosity and hardness as to enable the material to flow freely from one bag 6 to another, and so instantly adapt its distribution inside support cushion 3a to the buttock position of the user.
  • the lumbar support cushion 3b supports the user's back, and has two bags 6 arranged side by side on opposite sides of the centerline plane of the seat .
  • the two bags 6 communicate directly with each other, and are filled with a gelatinous material of such viscosity and hardness as to enable the material to flow freely from one bag 6 to the other, and so instantly adapt its distribution inside support cushion 3b to the back position of the user.
  • the two bags 6 of lumbar support cushion 3b may obviously also be isolated.
  • the pelvic and pelvic girdle support cushions 3c and 3d each have one bag 6 filled with a gelatinous material of greater viscosity and hardness than that of support cushions 3a and 3b, so as to achieve maximum body retention and prevent twisting movements of the upper part of the body in the presence of severe centrifugal forces.
  • thigh support cushion 3e has two bags 6 arranged side by side on opposite sides of the centerline plane of the seat, and which are isolated, but nevertheless filled with a gelatinous material of comparable viscosity to that of bags 6 of buttock and lumbar support cushions 3a and 3b, so as to assist blood circulation to and from the lower part of the legs.
  • ergonomic seat 1 Operation of ergonomic seat 1 is easily deducible from the foregoing description with no further explanation required.
  • the advantages of ergonomic seat 1 as described and illustrated herein are obvious: for different driving postures, the bags of gelatinous material inside support cushions 3 of the seat ensure correct, uniform body pressure on the seat and correct body retention, permit any necessary body movement, and provide for improved muscular activity.
  • one or more lumbar support cushions 3b with bags filled with gelatinous material provide for uniform, natural support of the backbone, without forcing the end of the backbone to assume an unnatural curve.
  • One or more inner bags 6 filled with gelatinous material in fact, adapt perfectly to any contour of the user's back.
  • support cushions 3 of ergonomic seat 1 may be fitted inside with both bags 6 of gelatinous material, and conventional air chambers inflated or deflated by an electronic central control unit to adjust the stiffness and shape of the seat as closely as possible to the driver's body and/or vehicle attitude.
  • bags 6 of gelatinous material would be interposed between the user's body and the air chambers inside support cushion/s 3 to adapt the surface shape of the cushion/s perfectly to the supported body parts .
  • seat 1 as described and illustrated herein may obviously also be used to advantage for other applications, such as the manufacture of pushchairs and prams .
