  • the present invention aims to eliminate the above drawbacks by proposing a device for changing the firmness of the seating area of a slatted base defined by a lifting part forming the back of the base and which is characterized in that that it comprises a rigid piece in the form of a plate placed under the slats of the seating area and movable relative to the frame of the box spring between a lower position at which the slats of the seating area can move freely and a higher position limiting the travel of the slats to a value corresponding to a maximum firmness of the seat area.
  • the rigid plate-shaped part is moved in a direction perpendicular to the plane of the frame of the bed base in synchronism with the pivoting of the lifting part forming the backrest so that the latter occupies its lower position in the stowed position within the frame of the bed base. the lifting part and its upper position in the maximum raised position of the lifting part.
  • the bed base comprises an electric motor for controlling the pivoting of the lifting part forming the backrest
  • the rigid plate-shaped part is displacement controlled by the electric motor by means of mechanical displacement means.
  • the mechanical means for moving the rigid piece in the form of a plate comprise two parallel bars mounted for rotation in the frame of the bed base transversely thereto and coupled to the motor shaft of the electric motor so as to be jointly driven in rotation; and at least two cam elements integral respectively with the two rotary bars and located below the rigid plate-shaped part so as to move the latter perpendicular to the rotary bars when jointly driven by the drive shaft.
  • the means for coupling the rotary bars to the motor shaft comprise two pairs of rods, each comprising a connecting rod for the two rotary bars and a connecting rod for one of the bars rotatable to the motor shaft by means of a lever arm secured to the motor shaft.
  • Each connecting rod of the two rotary bars is connected to these by means of lever arms.
  • each rotary bar carries two cam elements.
  • Each cam element is produced from a metal plate fixed perpendicular to the corresponding rotary support bar.
  • the rigid plate-shaped part is guided movement relative to the rotary bars by two pairs of guide tabs integral with the rigid part perpendicular thereto and engaged respectively on the two rotary bars passing through oblong holes in the guide tabs.
  • the pairs of rods, the pairs of cam elements and the pairs of guide tabs are arranged symmetrically to the longitudinal axis of the frame of the bed base.
  • the rigid part is a padded or padded rectangular metal plate.
  • Figure 1 is a schematic side view of a slatted base with partial cutaway showing the firmness change device according to the invention.
  • Figure 2 is a perspective view from below of the base according to arrow II of Figure 1 and showing the firmness change device in the low position.
  • Figure 3 is a view similar to that of Figure 2 showing the firmness change device in the high position of maximum firmness.
  • Figure 4 is a sectional view along line IV-IV of Figure 2.
  • FIG. 5 is a sectional view along the line V-V of FIG. 3.
  • Figure 6 is a sectional view along line VI-VI of Figure 2.
  • FIG. 7 is a perspective view along arrow VII of FIG. 2.
  • the reference 1 designates a bed base of the type with transverse slats 2 arranged transversely to the wooden frame 3 of the bed base which comprises a lifting part 4 consisting of a metal frame carrying transverse slats 2 and which can occupy a stowed position horizontal in frame 3 of the bed base and several raised inclined positions selectively adjustable by the user so as to constitute a backrest.
  • the movement of the lifting part 4 is controlled by an electric motor 5 fixed in the frame 3 of the bed base to one of the side members 6 thereof.
  • the electric motor 5 is activated by a manual control (not shown) connected to the latter by an electric cord.
  • the electric motor 5 has its motor shaft 7, arranged transversely between the longitudinal members 6 of the frame 3 of the bed base, which is mechanically coupled to the lifting part 4 by lateral arms 8 allowing pivoting around the axis defined by the motor shaft 7 of the lifting part 4.
  • the firmness of the seat area of the slats 2 defined by the part 4 occupying a raised position forming the backrest is automatically changed as a function of the pivoting of the lifting part 4.
  • the device for changing the firmness of this seating area comprises a rigid piece in the form of a plate 9, preferably metallic and rectangular, placed under the slats 2 of the seating area and which can be moved so guided relative to the frame 3 of the box spring between a lower position shown in FIGS. 2 and 4 at which the slats 2 of the seating area can freely swing under the weight of the person and an upper position shown in FIGS. 3 and 5 limiting the slats 2 travel at a value corresponding to maximum firmness of the seat area.
  • the slats 2 of the seating area provide the user lying on the bed base, via a mattress, with the usual feeling of comfort because the weight exerted on this area by the user's buttocks is not very high.
  • the rigid part 9 approaches the slats 2 of the seating area so as to limit the movement of its slats and to prevent the increasing weight of the user concentrating on the gluteal area thereof crushes the slats.
  • the movement of the rigid plate-shaped part 9, in a direction perpendicular to the plane of the frame 3 of the bed base 1, is controlled by the electric motor 5, the motor shaft 7 of which is coupled to the rigid part 9 by mechanical means. displacement of it.
  • These mechanical means comprise two rigid metallic and parallel bars 10, 11 rotatably mounted in the frame 3 transversely to the side members 6 thereof and coupled to the motor shaft 7 so as to be jointly driven in rotation in the same direction; and two pairs of cam members 12; 13 secured respectively to the two rotary bars 10; 11 and located below the rigid part 9 so as to move the latter perpendicular to the rotary bars 10, 11 when jointly driven by the drive shaft 7.
  • Each cam element 12, 13 is produced from a plate metal fixed perpendicularly to the corresponding rotary support bar 10, 11.
  • Each bar 10, 11 has each of its tubular end parts rotatably mounted on a cylindrical axis 14 fixed perpendicular to the corresponding spar 6, for example by a fixing screw 15 .
  • the means for coupling the rotary bars 10, 11 to the drive shaft 7 comprise two pairs of links 15, 16 each comprising a link 17 for pairing the two bars 10, 11 and connected to these bars by means of two arms lever 18 and a connecting rod 19 for connecting the rotary bar 10 to the motor shaft 7 by means of a lever arm 20 integral with the motor shaft 7.
  • Each link 19 is connected to the rotary bar 10 by the lever arm 18 connecting the bar 10 to the link 17.
  • each articulation axis 21 connecting a lever arm 20 to the corresponding link 19 is housed in a slot or oblong hole 22 made at the end of the connecting rod 19 and allowing the electric motor 5, when the rigid plate-shaped part 9 is in the low position, to have sufficient power to lift the rigid part 9.
  • the oblong holes 22 introduce a delay in the lifting of the plate 9 and making it possible not to increase the firmness of the seat area too quickly if the head is only raised slightly and not to overload the motor during the start of head or torso lift phase, phase where the motor is most requested d u power point of view.
  • the movement of the rigid part 9 is guided in the direction perpendicular to the plane passing through the rotary bars 10, 11 by two pairs of guide tabs 23, 24 fixed under the rigid part 9 perpendicularly to it, for example by means of fixing screws, and engaged respectively on the two rotary bars 10, 11 which pass through oblong holes 25, 26 respectively of the guide tabs 23, 24 allowing these to slide perpendicular to the respective bars 10, 11 .
  • the pairs of rods 15, 16, the pairs of cam elements 12, 13 and the pairs of guide tabs 23, 24 are arranged symmetrically to the longitudinal axis of the frame 3 of the bed base 1.
  • the lowering of the rigid plate-shaped part 9 is carried out by controlling the electric motor 5 so as to move the cam elements 12, 13 in the opposite direction to that indicated by the arrows in FIG. 4, the lowering movement of the rigid part 9 being effected by gravity or under the weight of the user.
  • the weight of the user which is maximum when the latter is seated with the part 4 raised in the maximum position, is effectively supported practically by the two rigid metal bars 10, 11.
  • the slats 2 of the seating area are practically in contact with the latter which is preferably padded or padded.
  • the invention has been described with reference to a bed base with an electric motor for pivoting control of the lifting part 4, but it is understood that it also applies to a bed base of the type with lifting part forming a manually operated backrest.
  • a bed base of the type with lifting part forming a manually operated backrest.
  • the movement of the rigid plate-shaped part can also be controlled by an independent electric motor possibly synchronized with the lifting motor of the lifting part forming the backrest.
  • the invention thus makes it possible to obtain a gluteal region of the flexible and comfortable bed base in the supine position and a firm gluteal region by change of firmness in the seated position.
