Definitions

  • the invention concerns a chair or armchair with adjustable headrest.
  • the chairs and armchairs made according to the known art include elements, such as armrests and headrests, which increase the comfort of the user.
  • These elements as well as other elements of the chair, like for example the backrest, comprise adjusting units that allow them to be set in the position that is most suited to the physical characteristics of the person who seats on the chair/armchair.
  • many known embodiments of the adjusting unit comprise a first element, substantially laminate and protruding from the headrest, and a second element, also laminate and belonging to the backrest, which are mutually pressure-fitted through screw means.
  • These screw means usually comprise a tightening knob for the user.
  • a first recognised drawback is represented by the fact that the means for coupling and adjusting the headrest project from the body of the chair, and therefore are an unpleasant element in the overall appearance of the chair.
  • the aim of the present invention is to overcome all the drawbacks described.
  • a first aim of the invention is to produce a chair having coupling and adjusting means for regulating the position of the headrest with respect to the backrest that are integrated in the profile of the backrest, differently from the equivalent chairs carried out according to the known art.
  • the first coupling and adjusting means are constituted by a plurality of recesses present in the insertion elements of the headrest and the second coupling and adjusting means are constituted by protrusions that are housed in said recesses and that are located in the seats made in the backrest.
  • the chair subject of the invention is not provided with knobs for the user or other projecting elements, thus achieving a more pleasant appearance than the equivalent chairs carried out according to the known art.
  • the coupling and adjusting means carried out according to the invention simplify the vertical movement of the headrest and therefore make it easier to find the optimal position for the user.
  • the headrest 7 is provided with an insertion element 8 slidingly housed in a seat 9 made in the backrest 6 and interacting with it through first coupling and adjusting means 10 provided in the insertion element 8 and second coupling and adjusting means 11 made in the seat 9 and cooperating with the first coupling and adjusting means 10 to define different positions of the headrest 7 with respect to the backrest 6.
  • Said pocket 13 is delimited by a pair of laminate frame units 14, 15, facing each other, that form the backrest 6 and that are joined, as can be seen in Figure 2, with fastening means 16.
  • the latter in the preferred embodiment of the invention described herein, are constituted by a plurality of through holes 17 present in a first frame unit 14 and such as to allow the shaped protrusions 18 projecting from the second frame unit 15 of the pair of frame units to be fixed into them.
  • the second frame unit 15 has the front surface 19 that is substantially continuous and faces the corresponding surface 20 of the first frame unit 14 that presents a shaped portion 21 which, when joined to said second frame unit 15, defines the pocket 13.
  • the pocket may be formed by a pair of shaped portions facing each other, each made in one of the frame units that form the backrest.
  • the backrest may be constituted by a single frame unit where the pocket is formed.
  • the insertion elements may be more than one and have a substantially tubular shape, so that the corresponding seats may be dead holes made in the profile of the backrest in a number and position corresponding to said insertion elements.
  • the pocket 13 As regards the pocket 13, as shown in Figure 3, it comprises a pair of rails 22 in which the lateral edges 23 of the insertion element 8 of the backrest 7 are fitted.
  • each of said rails 22 is constituted by a tang 24 projecting towards the inside of the pocket 13 and arranged parallel to the surface defined by the backrest 6.
  • the chair 1 carried out according to the invention comprises also means 25 suited to stop the sliding movement of the headrest 7, comprising in one direction the end 26 of the rails 22, and in the other direction a pair of stop teeth 27 belonging to the laminate element 12 and slidingly fitted in a corresponding slot 28 made in the backrest 6, in front of and parallel to each tang 24.
  • stop tooth 27 has a concave part suited to be coupled with the upper edge 29 of the corresponding slot 28 when the headrest 7 is completely extracted from the backrest 6.
  • the first coupling and adjusting means 10 comprise to rows 40, 41 of recesses 42, both made in the insertion element 8 of the headrest 7 and arranged along two longitudinal axes U, T substantially parallel to each other and to the sliding direction V of the headrest 7 in the pocket 13 in the backrest 6.
  • the second coupling and adjusting means 11 comprise, with reference to Figure 4, two protrusions 30 belonging to corresponding laminate sections 31.
  • Said slots 32 are suited to make the laminate sections 31 , and therefore also the protrusions 30 present on them, elastically yielding.
  • Each protrusion 30, as can be seen in the detail of Figure 5, is suited to be housed in one of the recesses 42 present in the insertion element 8 of the headrest 7 to define a constraint on the sliding movement of the headrest 7 in the backrest 6.
  • the protrusions can be made in each one of the insertion elements of the headrest and will be suited to house the second coupling and adjusting means that comprise at least one plurality of recesses positioned in one or more laminate sections obtained in the backrest and defined between two slots defining two longitudinal axes substantially parallel to the longitudinal axis defined by the backrest.
  • the slots will be suited to make the corresponding laminate sections and recesses elastically yielding.
  • the user exerts on the headrest 7 a traction or compression force, lifting or lowering it.
  • the headrest 7 thus slides along its longitudinal axis V in the direction desired by the user.
  • the latter stops lifting or lowering it and allows the protrusions 30 to stop inside the corresponding recesses 42 just reached, thus reestablishing the fixing constraint that prevents further movements of the headrest 7.
  • the headrest 7 may reach its end-of-stroke positions.
  • the end of stroke is represented by the end 26 of the rail 22, while if the headrest 7 is lifted with respect to the backrest 6, the end of stroke is represented by the interaction between each stop tooth 27 and the upper edge 29 of the corresponding slot 28 in which it slides.
  • the chair carried out according to the invention achieves the set aims.
  • the chair subject of the invention achieves the aim to comprise coupling and adjusting means for regulating the position of the headrest that are completely integrated in the profile of the backrest, since the first and second coupling and adjusting means are fully defined inside the seat formed in the profile of the backrest itself.
  • the chair subject of the invention also achieves the aim to make the use of the coupling and adjusting means more comfortable compared to the chairs belonging to the known art, since the adjustment is carried out exclusively by exerting a force on the headrest itself.
