Definitions

• the present invention relates to seats as they constitute furniture.
• the usual seats include a set of feet ensuring no static support on the ground, these feet carrying a substantially horizontal surface or seat proper and, in general, a backrest constituted by a substantially vertical surface carried by the uprights extending the feet. back.
• Cer ⁇ tain these seats can comprise means for regulating or elastic change in the inclination of the backrest with a mounting varia ⁇ limited inclination to the surface forming the seat.
• the object of the present invention is to create a seat which can be used in various ways, the seat and the backrest adapting to the morphology and the natural position of the user's body, whatever the way in which the seat is used.
• REPLACEMENT SHEET top are secured to the support frame each by an articulation around at least the axis perpendicular to the median plane of these surfaces which passes substantially through the geometric center of gravity of the said surface.
• each of the surfaces constituting the seat and the backrest being mounted for free rotation around its articula ⁇ tion adapts its inclination to that of the part of the body which bears thereon.
• each surface is articulated at the end of an upright and the two uprights are hinged together by an axis parallel to the axes of articulation of the surfaces, at least one of the lower ends of the two uprights carrying a crosspiece ensuring the transverse stability of the ground support.
• the two uprights are hinged together, not by a parallel axis, but by interpenetration of one of the uprights inside the other, which has in its center and on all its length a recess, and two cleats integral with said upright and parallel to the axes of articulation of the surfaces, spaced apart by at least the thickness of the first upright.
• each surface forming a seat or a backrest or a top and bottom plate about its axis of articulation is substantially equal to 360 ° so that the said surface can be brought to bear against the two upper and lower faces of the upright at the end of which it is articulated.
• the plates materializing the surfaces are balanced around their axis of articulation so as to come to rest, in the normal position of the unused seat, against the upper face of the upright which terminates there.
• Figure 1 is a side elevational view of the seat in non-use position
• Figure 2 is a perspective view from the rear
• Figure 3 is a side elevational view in the folded state
• Figures 4 to 7 are diagrams illustrating different ways of using the seat of the
• the seat shown by way of illustrative example comprises two uprights (l) and (2) which are either articulated in X around an axis (3), or which are articulated simply by sliding ent of the upright (1) to the 'interior of the recess ent of the upright (2) and the space delimited by the two battens (6).
• brackets can be placed on either side and outside the upright (2), they then allow the seat to be fully folded by penetrating the upright (1) inside the upright (2) in the case of uprights of straight form.
• the battens (6) can be placed inside the internal walls of the upright (2) parallel to the axes (10) and (13) they allow a recessing of the uprights (1) and (2) when they are bent in the same direction.
• the uprights are bent in opposite directions they allow a head-to-tail stacking of a series of seats.
• the displacement of the upright (1) inside the upright (2) makes it possible to choose the desired spacing between the low plate (4) and the high plate (5); the user will thus obtain better comfort by perfectly adapting the seat to its measurements.
• Figure (2) shows an upright (1) which carries the seat surface (4), consisting of a single element itself constituted by a slightly curved bar, while the upright (2) which carries the surface forming a backrest (5) consists of two parallel elements, also formed by a slightly curved bar.
• the amount (1) comprises at least one element while the amount (2) comprises at least two elements.
• the upright (1) is housed between the two elements of the upright (2) which are also joined on either side of the articulation of the axis (3) by tas ⁇ buckets (6) which limit the opening of the X by stop of the upright (1).
• At the lower free ends of the uprights (1) and (2) are fixed perpendicular crosspieces (7) which ensure the transverse stability of the seat.
• the surface forming a seat (4) which comprises a rigid base (8) and a padding (9) is fixed to the free upper end of the upright (1) by a transverse axis (10). Due to this articulation, the surface forming a seat can freely tilt between a position in which it is in abutment with the upper part of the upright (1) as illustrated in FIG.
• the same surface forming the backrest (5) is constituted by a rigid reinforcement plate (11) and a padding (12) and it is articulated at the free upper end of the uprights (2) by a transverse axis (13) .
• the surface forming the backrest can, thanks to this mounting, tilt freely between a position in which it is in abutment against the front part of the uprights (2) as shown in FIG. (1) and a position in which it is resting against the rear part of said uprights (2) as shown in Figure (3).
• the seat is used as a conventional low seat, the surface forming a seat or low tray being situated for example 24 cm from the ground.
• the low plate (4) takes an inclination which adapts to the slope of the thigh in this seated position and the high plate or backrest (5) rests against the back of the user.
• Figure (6) represents a relaxed position, the subject being seated on the high platform or backrest (5) with the knees resting on the low platform (4) In this position the user's center of gravity is located at mid-distance from the hip and knee and the seat adapts perfectly to the user's body, respecting the particular "femur-tibia" angle.
• Figure (7) shows a use in which the high tray or backrest (5) is used as a seat. Thanks to the inclination taken by this plate (5), a good lumbar locking and a good attitude of the spine are obtained.
