Definitions

  • the present invention relates to an improved device for tilting, in an adjustable and combined manner, the backrest and the seat of an armchair which are hinged together and on the base of this armchair, the armrests of which are articulated on the backrest and connected to the base by l 'through racks.
  • the seated person To modify the backrest tilt setting, the seated person must lean forward, on the one hand, to unlock the racks and, on the other hand, to move the backrest without losing balance and tilting backward.
  • the object of the present invention is to remedy these drawbacks while retaining the advantage of the aforementioned known device, by means of which any mobile mounting of the front joints can be eliminated.
  • the geometric axis of articulation of the backrest on the seat is placed in front of the geometric axis of articulation of the backrest on the base, and located, when the backrest is in the fully raised position. and in the completely lowered position, below and respectively above the horizontal passing through this geometric axis of articulation of the backrest on the base.
  • the extreme positions of the geometric axis of articulation of the backrest on the seat are substantially symmetrical with respect to the horizontal passing through the geometric axis of articulation of the backrest on the base.
  • This improved device of the invention can be applied to the V-shaped base of the folding chair illustrated by the aforementioned French patent No. 2,596,261, which base, on each side, comprises a front foot and a rear foot, the upper ends of which are articulated one on the other and provided with a finger cooperating with the rack of the corresponding armrest.
  • the axes of articulation of the seat and the back are carried respectively by these front feet and these rear feet, while the axes of articulation of the seat on the back are located in front of the axes of articulation of the backrest on the hind feet.
  • the improved device of the invention can also be applied to the rigid base of an armchair, a base which consists of two lateral arches, each of which comprises a branch or front leg and a branch or rear leg connected by a cross member of medium level and making body with an upper middle bend fitted with the finger cooperating with the rack of the corresponding armrest.
  • the axes of articulation of the seat and the back are carried respectively by the front legs and the crosspieces, while the axes of articulation of the seat on the back are located in front of the axes of articulation of the file on the sleepers.
  • the improved device according to the invention can also be applied to other types of plastic armchair, for example to those comprising a folding frame in X, provided, however, that at least one additional part, such as a link, is provided and suitably arranged.
  • Figure 1 shows a folding chair with a V-shaped base, the seat and back of which are adjustable in inclination.
  • the chair is made of injection molded plastic.
  • this chair has a normal seating level and the adjustments allow the occupant to be more or less leaning back.
  • the armchair comprises a backrest 1 and a seat 2 having lateral ears 3, 4 respectively, two of which are integral with aligned pins 5 which pass through holes made in the two ears, in order to constitute articulations situated at the bottom of the backrest and at the back of the seat.
  • the chair also has a base 6 consisting of two front lateral legs 7 joined together by means of a low cross member 8 and by two rear lateral legs 9 also joined together by means of a lower crosspiece 10. On each side, the front 7 and rear 9 feet are connected, at their upper end, by a hinge pin or pin 11.
  • the seat 2 is supported at the front by the front legs 7 by means of aligned pins or pins 12.
  • the backrest 1 is supported at its base by the rear legs 9 by means of aligned pins or pins 13.
  • the armchair finally comprises two lateral armrests 14 extending between the backrest 1 and the top of the base 6 to ensure the stability of the armchair, the comfort for the seated person and the adjustment of the inclinations.
  • each armrest 14 is connected at the rear, to the backrest 1 by means of aligned pins or trunnions 15 and in its central zone, to the base 6 by means of a rack 16 molded from the armrest considered and the notches 17 of which, not limited to four in the example shown, are capable of cooperating selectively with a finger 18 projecting from a tab 19 of the corresponding rear foot 9.
  • the geometric axis of the axes or pins 5 of articulation of the seat 2 on the backrest 1 is arranged in front of the geometric axis of the axes or pins 13 of articulation of the backrest 1 on the rear legs 9. Furthermore, if we consider the horizontal plane P passing through the geometric axis 13 ( Figure 2), the extreme positions 5b and 5h of the geometric axis of articulation 5 connecting the seat 2 in the backrest 1 are located below and above this plane P, the positions Sb and 5h of the common articulation corresponding to the position of the backrest 1 completely raised (shown in solid lines in FIG. 2) and respectively in the position of said fully lowered backrest (shown in broken lines in this figure 2).
  • the plane Q connecting the articulation 5 in these positions 5b and 5h is substantially vertical, which amounts to minimizing the deflection f of the circular path T connecting said positions 5b and 5h, that is to say of the trajectory of the joint 5 when the backrest 1 pivots according to the amplitude maximum angular around the joint 13 of the hind feet 9.
  • this kinematics makes it possible to distribute the forces so that the weight of the seated person has the effect of balancing the system and thus allowing this person to unlock the racks of the armrests and to modify the inclination of the backrest without having to get up or lean too far forward.
  • FIG. 3 shows an armchair made of plastic with a rigid base constituted by two lateral arches 20.
  • Each arch comprises a right front leg 21 and an arched rear leg 22 integral with one another by an upper bend 23 and a crosspiece of medium level 24.
  • the base also has, from molding with the arches 20, low crosspieces 8 and 10 connecting together the front legs 21 and the rear legs 22 respectively.
  • This chair comprises, like that of FIG. 1, a backrest 1, a seat 2 and armrests 14.
  • the backrest 1 is carried by the crosspieces 24 by means of the axes or articulation pins 13 connecting this backrest to legs 25 of these crosspieces 24.
  • the backrest 1 is also coupled via the articulations 15 to the armrests 14, which are connected to the elbows 23 of the arches 20 in an adjustable manner by means of racks 16 of said armrests cooperating selectively with fingers 18 protruding on legs 19 of said elbows.
  • the seat 2 is connected by the joints 12 to the front legs 21 and by the joints 5 to the backrest 1.
