Definitions

  • This invention finds application in the field of mechanical structures made of special materials, and particularly relates to an ergonomic support structure.
  • the invention relates to a process for making the above structure.
  • Cover pads of foam material are known to be used to enhance comfort and ergonomic benefit of support structures, such as bicycle saddles, car seats or the like.
  • gel inserts are being increasingly used at the areas subjected to the highest pressure by users, to provide comfort where this is most needed.
  • Gel is preferable as compared with foam, due to its higher viscoelasticity and better ergonomic properties.
  • WO2004-089682 discloses an ergonomic cushion for motor vehicle seats, having gel inserts at the ischial regions.
  • U.S. Pat. No. 6,454,352 discloses a car seat with encapsulated gel pads, capable of deformation when in contact with moving parts of a user.
  • the object of this invention is to overcome the above drawbacks, by providing a support structure that is highly efficient and relatively cost-effective.
  • a particular object is to provide a support structure having a light weight and a high strength.
  • a further object is to provide a support structure that can be customized, i.e. adapted to the anthropometric structure of any user whatever.
  • Another object of the invention is to provide a support structure that is pleasant to the sight.
  • Yet another object of the invention is to provide a highly practical and cost-effective process for making the structure of the invention.
  • an ergonomic support structure which comprises a main body with a viscoelastic insert permanently anchored thereto, wherein the main body has at least one first layer made of a material selected from those having a relatively low density and a relatively high mechanical strength, said first layer being associated to at least one second layer of polymer resin, for monolithically anchoring said at least one insert.
  • the structure of the invention has a very light weight and enhanced sturdiness, and allows to avoid the use of pads, that were used as comfort elements in prior art structures. This allows to make structures that are both comfortable and of a very light weight.
  • the structure of the invention is highly comfortable, particularly suitable for the fabrication of bicycle saddles, car seats, chairs, wrist supports or the like.
  • this at least one insert may be placed over said at least one first layer to define a free contact surface for the user suitable of controlled deformation.
  • the structure of the invention meets the needs of various users, regardless of specific anthropometric structures of the parts of human bodies in contact with the structure.
  • the natural ergonomic properties of the viscoelastic material allow the structure to be easily and comfortable adapted to anyone.
  • the lack of a pad provides an assembly that is highly pleasing to the sight, a non-negligible advantage in the field of sports and leisure, which is highly influenced by fashion and aesthetics.
  • the structure of the invention may have a thermoplastic cover layer, placed over said at least one insert and the top surface of said at least one first layer.
  • the structure is highly pleasant to the touch and safe, as it protects users from any rupture of the first layer which might otherwise have dangerous structural discontinuities and injure the users.
  • a process for making an ultralight ergonomic support structure like the one disclosed above which includes the steps of: providing a mold having an inner cavity of a predetermined shape which corresponds to the external configuration of a main body of a support structure; opening said mold and laying thereon at least one first layer made of a material selected from those having a relatively low density and a relatively high mechanical strength; placing at least one third layer of a polymer material having relatively high adhesive properties on said at least one first layer; placing at least one viscoelastic insert in said mold; placing at least one second layer of a polymer resin; sealing said mold and heating it to a predetermined operating temperature; cooling said mold to a predetermined final temperature and opening said mold and removing the finished support structure.
  • FIG. 1 is an axonometric view of a support structure according to the invention
  • FIG. 2 is an axonometric view of a detail of FIG. 1 ;
  • FIG. 3 is a sectioned view of the structure of the invention, as taken along a plane
  • FIG. 4 is another sectioned view of the structure of the invention, as taken along a plane IV-IV;
  • FIG. 5 shows a flowchart of a process for making the support structure of the invention.
  • the structure of the invention may be, for instance, a part of a chair, a bicycle saddle, a wrist support or a car seat, as shown in FIG. 1 .
  • the structure 1 comprises a main body 2 , with the viscoelastic insert 3 , preferably made of polyurethane gel, permanently anchored thereto.
  • the main body 2 may include, for instance, a first layer 4 associated to a second layer 5 .
  • the member 4 has a low density and a high mechanical strength, i.e. a high resistance to compressive and/or tensile and/or bending and/or torsional and/or shearing stresses.
  • the second layer 5 is essentially composed of one or more thermoplastic or thermosetting resins, possibly reinforced.
  • the first layer 4 may include a metal sheet 6 , e.g. made of titanium, aluminum, stainless steel, magnesium or the like, associated to the layer 5 , and wholly or partly covered thereby, as shown in FIG. 3 .
  • a metal sheet 6 e.g. made of titanium, aluminum, stainless steel, magnesium or the like, associated to the layer 5 , and wholly or partly covered thereby, as shown in FIG. 3 .
  • the inserts 3 may be anchored by an adhesive polymer film 8 , which is used to bind the insert 3 and the sheet 6 , as shown in FIG. 4 .
  • the insert 3 may be covered by a protective layer 9 of a material adapted to oppose its high inherent adhesiveness, such as a polyurethane paint.
  • the structure 1 may have a thermoplastic cover layer 10 , having protection functions.
  • the layer 10 may be transparent, so that the aesthetically pleasing connection between the material of the body 2 and the gel of the insert 3 is visible.
  • a process for making the structure 1 includes the following steps.
  • a mold is provided, having an inner cavity of a predetermined shape, which corresponds to the external configuration of the main body 2 of the support structure.
  • step b) the mold is opened and the first layer 4 is laid thereon, and in step d) one or more inserts 3 are placed thereon after a step c) in which the adhesive 8 is applied on the member 4 .
  • step e) the second layer of polymer resin 5 is laid, to provide a monolithic structure.
  • the cover layer 10 may be placed in the mold to protect the assembly, thereby providing the above mentioned advantages.
  • step f) the mold is hermetically sealed and heated to a predetermined operating temperature, which may be in a range of 20° C. to 300° C., and will preferably be of about 120° C. Such temperature will be typically close to the glass transition temperature of the resin layer 5 .
  • a predetermined operating temperature which may be in a range of 20° C. to 300° C., and will preferably be of about 120° C.
  • Such temperature will be typically close to the glass transition temperature of the resin layer 5 .
  • chemical and/or mechanical bonds will be formed to form a monolithic assembly from the body 2 and the inserts 3 .
  • the final step h will follow, during which the mold is opened, and the finished support structure 1 is removed therefrom.
