ABSTRACT OF THE DISCLOSURE
The armchair according to this invention com-prises a backrest and a seat articulated on each other and on the ground-engaging elements thereof whose armrests are themselves articulated on the backrest and joined to the ground-engaging elements via racks. In the device of the invention, the geometrical pivot axis of the backrest on the seat lies in front of the geometrical pivot axis of the backrest on the ground-engaging elements, and located, when the backrest is in completely erect position and in completely lowered position, respec-tively below and above the horizontal line passing through this geometrical pivot axis of the backrest on the ground-engaging elements.
Description
~:0~7S85 --1~
FIELD OF THE INVENTION
The present invention relates to an improved device for inclining, in adjustable and conjugate manner, the backrest and seat of an armchair which are articulated on each other and on the ground-engaging elements of this armchair, of which the armrests are articulated on the backrest and connec-ted to the legs via racks.
BACKGROUND OF THE INVENTION
i0 Such a known device is illustrated in French Patent No. 2 596 261 which teaches -that the geometri-cal pivot axis of the backrest on the seat lies behind the geometrical pivot axis of the backrest on the ground-engaging elements and located horizon-15 tally with respect to the preceding axis when the backrest is inclined in mid-position. In this way, the end positions of the pivot pin of the backrest on the seat are substantially vertical with respect to each other. Consequently, the horizontal projec-20 tion of the path of this pivot pin of the backreston the seat is relatively little and, as a result, it may be absorbed by the clearances of all the pivot pins of the armchair. Under these conditions, the inclination of the backrest is accompanied 25 by an inclination of the seat with a virtually negligible horizontaL translation of this seat, with the result that the mobile assembly of the front pivot pin of the seat on the ground-engaging elements, which was necessary in the prior embodi-30 ments, may be eliminated.
However, this particular arrangement of thepivot pins presents the drawback of over-stressing the racks of the armrests of the armchair when a person is sitting therein, being given that the 35 weight of the body tends to lower the backrest.
)17S85 Furthermore, in order to modify the adjustment of the inclination of the backrest, the person sitting down must lean forwards, on the one hand to unlock the racks and, on the other hand, to move the backrest without losing his balance and tipping backwards.
It is an object of the present invention to overcome these drawbacks whilst conserving the advantage of the known device set ~orth hereinabove whereby any mobile assembly of the front pivot pins may in fact be eliminated.
SUMMARY OF THE INVENTION
To that end and in accordance with the inven-tion, the geometrical pivot axis of the backrest on the seat lies in front of the geometrical pivot axis of the backrest on the ground-engaging elements, and located, when the backrest is in completely erect position and in completely lowered position, respectively below and above the horizontal line passing through this geometrical pivot axis of the backrest on the ground-engaging elements.
The end positions of the geometrical pivot axis of the backrest on the seat are substantially symmetrical with respect to the horizontal line passing through the geometrical pivot axis of the backrest on the ground-engaging elements.
This improved device of the invention may be applied to the V-shaped ground-engaging elements of the foldable armchair illustrated in French Patent No. 2 596 261 mentioned above, which ground-engaging elements comprise, on each side, a front leg and a rear leg whose upper ends are pivoted on each other and provided with a finger cooperating with the rack of the corresponding armrest. In ~5 this application, the pivot pins of the seat and _3_ Z~758S
of the backrest are borne by these front legs and rear legs, respectively, whilst the pivot pins of the seat on the backrest lie in front of the pivot pins of the backrest on the rear legs.
The improved device of the invention may also be applied to the rigid ground-engaging elements oE an armchair, which ground-engaging elements are constituted by two lateral bows of which each comprises a front branch or leg and a rear branch or leg connected by a stretcher at mid-height and integral with an upper median bend provided with the finger cooperating with the rack of the corres-ponding armrest. In this particular application, the pivot pins of the seat and of the backrest are respectively borne by the front legs and the stretchers, whilst the pivot pins of the seat on the backrest are located in front of the pivot pins of the backrest on the stretchers.
The improved device according to the invention may also be applied to the other types of armchair made of plastics material, for example to those comprising ground~engaging elements foldable in X form, on condition, however, that at least one additional piece, such as a connecting rod, is provided and suitably disposed.
BRIEF DESCRIPTION OF T~E DRAWINGS
The invention will be more readily understood on reading the following description with reference to the accompanying drawings, in which:
Figure 1 is an elevational view showing, seen from inside, the right-hand side of a foldable armchair with ground-engaging elements in V-form, to which armchair the device of the invention is applied.
Figure 2 is a diagram showing, on a larger _4 2~17585 scale, the advantages of the kinematics of this device.
Figure 3 is a view similar to Figure 1 illustra-ting the application of the device of the invention to an armchair having rigid ground-engaging elements.
DETAILED DESCRIPTION OF THE DRAWINGS
Referring now to the drawings, Figure 1 shows a foldable armchair with ground-engaging elements in V-form, whose seat and backrest are adjustable 10 in inclination in conjugate manner. The armchair is advantageously made of injection-moulded plastics material.
As shown, this armchair presents a normal seat level and the adjustments enable the occupant 15 to be in a more or less rearwardly reclining position.
In fact, such an armchair is intended for relaxing and sun-bathing. Consequently, the level of its seat is lower and, in sun-bathing position, the seat and the backrest are in line with each 20 other, substantially horizontally (Figure 2).
The armchair comprises a backrest 1 and a seat 2 presenting lateral ears 3, 4 respectively, of which two are integral with aligned pins 5 which pass through holes made in the two ears, in order 2~ to constitute articulations located at the base of the backrest and to the rear of the seat.
The armchair also comprises ground-engaging elements 6 constituted by two front lateral legs 7 joined by means of a low stretcher 8 and by two rear lateral legs 9 likewise joined by means of a low stretcher 10. On each side, the front and rear legs 7 and 9 are joined, at their upper end, by a pivot pin 11.
Seat 2 is supported at the front by the front legs 7 by means of aligned pins 12. Backrest l _5~ 7585 is supported at its base by the rear legs 9 by means of aligned pins 13.
Finally, the armchair comprises two lateral armrests 14 extending between the backrest 1 and the top of the ground-engaging elements 6 to ensure stability of the armchair, comfort for the person sitting in it, and adjustment of the inclinations.
To that end, each armrest 14 is connected at the rear to the backrest 1 by means of aligned pins 15 and, in its median zone, to the ground-engaging elements 6 by means of a rack 16 moulded with the armrest in question and whose notches 17, four in the example shown, although this number is non-limiting, are capable of cooperating selectively with a finger 18 projecting from a lug 19 on the corresponding rear leg 9 As shown in Figures 1 and 2, the geometrical axis of pins 5 for seat 2 to pivot on backrest 1, lies in front of the geometrical axis of pins 13 for backrest 1 to pivot on the rear legs 9.
Furthermore, if the horizontal plane P passing through the geometrical axis 13 (Figure 2) is con-sidered, the end positions 5b and 5h of the geometxi-cal pivot axis 5 joining seat 2 to backrest 1 lie below and above this plane P, the positions 5b and 5h of the common articulation corresponding respectively to the position of the completely erect backrest 1 (shown in solid lines in Figure 2) and to the position of the completely lowered backrest (shown in broken lines in Figure 2). The plane Q joining pivot axis 5 in these positions 5b and 5h is substantially vertical, this reducing to a minimum the camber f of the circular path T joining said positions 5b and 5h, i.e. of the path of axis 5 when the backrest 1 pivots by the -6- 2 0~ ~585 maximum angular amplitude about axis 13 of the rear legs.
As camber f is very little, the functional clearances in the articulations are sufficient to compensate it, this making it possible to dispense with using a mobile acsembly, for example by connec-ting rod, of the pin 12 for seat 2 to pivot on front legs 7.
Furthermore, and especially, these kinematics make it possible to distribute the Eorces so that the weight of the person sitting down has for its effect to balance the system and thus to allow this person to unlock the racks of the armrests and to modify the inclination of the backrest without having to get up or to lean too far forwards.
The device described hereinabove is applicable to other types of armchairs and in particular to the one shown in Figure 3.
This Figure 3 shows an armchair made of plastics material with rigid ground-engaging elements, consti-tuted by two lateral bows 20. Each bow comprises a straight front leg 21 and an arcuate rear leg 22 integral with each other by an upper bend 23 and a stretcher 24 at mid-height. The ground-engaging elements also present, moulded with the bows 20, low stretchers 8 and 10 joining together the front legs 21 and back legs 22, respectively.
Iike the one of Figure 1, this armchair compri-ses a backrest 1, a seat 2 and armrests 14. Backrest 1 is borne by stretchers 24 via pivot pins 13 joining this backrest to lugs 24 on these stretchers 24.
Backrest 1 is fur1:her coupled via pins 15 to armrests 14, which are adjustably joined to ~he bends 23 of the bows 20 by means of racks 16 on said armrests cooperating selectively with fingers 18 projecting _7_ ~0~75~5 from lugs 19 on said bends. Seat 2 is joined by pivot pins 12 to the front legs 21 and by pivot pins 5 to backrest l.
In this armchair according to Figure 3, with rigid ground-engaging elements, pivot pins 5 and 13 are disposed in the same manner and for the same result as the pins, bearing the same references, of the armchair of Ftgure l with ground-engaging elements in V form. Consequently, the comments lO set forth hereinbefore with reference to Figure 2 for the armchair of Figure 1 are valid for the armchair according to Figure 3.
The device employed and illustrated in this Figure 2 is, of course, applicable to all other types of armchairs, on condition that additional modes of connection are provided where necessary.
Furthermore, the pivot pins described may be replaced by any other equivalent means.

The invention will be more readily understood on reading the following description with reference to the accompanying drawings, in which:
Figure 1 is an elevational view showing, seen from inside, the right-hand side of a foldable armchair with ground-engaging elements in V-form, to which armchair the device of the invention is applied.
Figure 2 is a diagram showing, on a larger _4 2~17585 scale, the advantages of the kinematics of this device.
Figure 3 is a view similar to Figure 1 illustra-ting the application of the device of the invention to an armchair having rigid ground-engaging elements.
DETAILED DESCRIPTION OF THE DRAWINGS
Referring now to the drawings, Figure 1 shows a foldable armchair with ground-engaging elements in V-form, whose seat and backrest are adjustable 10 in inclination in conjugate manner. The armchair is advantageously made of injection-moulded plastics material.
As shown, this armchair presents a normal seat level and the adjustments enable the occupant 15 to be in a more or less rearwardly reclining position.
In fact, such an armchair is intended for relaxing and sun-bathing. Consequently, the level of its seat is lower and, in sun-bathing position, the seat and the backrest are in line with each 20 other, substantially horizontally (Figure 2).
The armchair comprises a backrest 1 and a seat 2 presenting lateral ears 3, 4 respectively, of which two are integral with aligned pins 5 which pass through holes made in the two ears, in order 2~ to constitute articulations located at the base of the backrest and to the rear of the seat.
The armchair also comprises ground-engaging elements 6 constituted by two front lateral legs 7 joined by means of a low stretcher 8 and by two rear lateral legs 9 likewise joined by means of a low stretcher 10. On each side, the front and rear legs 7 and 9 are joined, at their upper end, by a pivot pin 11.
Seat 2 is supported at the front by the front legs 7 by means of aligned pins 12. Backrest l _5~ 7585 is supported at its base by the rear legs 9 by means of aligned pins 13.
Finally, the armchair comprises two lateral armrests 14 extending between the backrest 1 and the top of the ground-engaging elements 6 to ensure stability of the armchair, comfort for the person sitting in it, and adjustment of the inclinations.
To that end, each armrest 14 is connected at the rear to the backrest 1 by means of aligned pins 15 and, in its median zone, to the ground-engaging elements 6 by means of a rack 16 moulded with the armrest in question and whose notches 17, four in the example shown, although this number is non-limiting, are capable of cooperating selectively with a finger 18 projecting from a lug 19 on the corresponding rear leg 9 As shown in Figures 1 and 2, the geometrical axis of pins 5 for seat 2 to pivot on backrest 1, lies in front of the geometrical axis of pins 13 for backrest 1 to pivot on the rear legs 9.
Furthermore, if the horizontal plane P passing through the geometrical axis 13 (Figure 2) is con-sidered, the end positions 5b and 5h of the geometxi-cal pivot axis 5 joining seat 2 to backrest 1 lie below and above this plane P, the positions 5b and 5h of the common articulation corresponding respectively to the position of the completely erect backrest 1 (shown in solid lines in Figure 2) and to the position of the completely lowered backrest (shown in broken lines in Figure 2). The plane Q joining pivot axis 5 in these positions 5b and 5h is substantially vertical, this reducing to a minimum the camber f of the circular path T joining said positions 5b and 5h, i.e. of the path of axis 5 when the backrest 1 pivots by the -6- 2 0~ ~585 maximum angular amplitude about axis 13 of the rear legs.
As camber f is very little, the functional clearances in the articulations are sufficient to compensate it, this making it possible to dispense with using a mobile acsembly, for example by connec-ting rod, of the pin 12 for seat 2 to pivot on front legs 7.
Furthermore, and especially, these kinematics make it possible to distribute the Eorces so that the weight of the person sitting down has for its effect to balance the system and thus to allow this person to unlock the racks of the armrests and to modify the inclination of the backrest without having to get up or to lean too far forwards.
The device described hereinabove is applicable to other types of armchairs and in particular to the one shown in Figure 3.
This Figure 3 shows an armchair made of plastics material with rigid ground-engaging elements, consti-tuted by two lateral bows 20. Each bow comprises a straight front leg 21 and an arcuate rear leg 22 integral with each other by an upper bend 23 and a stretcher 24 at mid-height. The ground-engaging elements also present, moulded with the bows 20, low stretchers 8 and 10 joining together the front legs 21 and back legs 22, respectively.
Iike the one of Figure 1, this armchair compri-ses a backrest 1, a seat 2 and armrests 14. Backrest 1 is borne by stretchers 24 via pivot pins 13 joining this backrest to lugs 24 on these stretchers 24.
Backrest 1 is fur1:her coupled via pins 15 to armrests 14, which are adjustably joined to ~he bends 23 of the bows 20 by means of racks 16 on said armrests cooperating selectively with fingers 18 projecting _7_ ~0~75~5 from lugs 19 on said bends. Seat 2 is joined by pivot pins 12 to the front legs 21 and by pivot pins 5 to backrest l.
In this armchair according to Figure 3, with rigid ground-engaging elements, pivot pins 5 and 13 are disposed in the same manner and for the same result as the pins, bearing the same references, of the armchair of Ftgure l with ground-engaging elements in V form. Consequently, the comments lO set forth hereinbefore with reference to Figure 2 for the armchair of Figure 1 are valid for the armchair according to Figure 3.
The device employed and illustrated in this Figure 2 is, of course, applicable to all other types of armchairs, on condition that additional modes of connection are provided where necessary.
Furthermore, the pivot pins described may be replaced by any other equivalent means.
