Definitions

the invention relates to a rest and relaxation chair and in particular a chair provided with a footrest, which can be tilted variably from the sitting position to the lying position.
the invention aims to remedy these drawbacks by proposing a rest or relaxation chair comprising a backrest, a seat and a footrest, the footrest and the backrest being articulated to the seat respectively at the front and at the rear of the latter, characterized in that the seat is mounted articulated on a horizontal axis integral with the sides or support frame of the chair and in that the back rest rests by its lower end in a movable manner on a cam profile also integral with said support frame, the footrest and the backrest being connected by a link articulated under the seat by its ends on each of them, a control means making it possible to variably adjust the inclination of the chair between the sitting position and the lying position by moving the lower end of the backrest on said cam profile.
the set of three seat, footrest and backrest planes therefore forms an articulated assembly bearing on the one hand, on the axis of the seat, and on the other hand, on the cam profile by the lower back end.
the connection between the footrest plane and the backrest plane and the curvature of the cam profile are determined in order to obtain relative inclinations of the planes conducive to rest and relaxation of the people (variable according to these) when the end of the backrest moves on the cam profile between the sitting position and the lying position.
the position of the seat axis on the support frame of the chair is also an important parameter in the evolution of the plans relative to each other.
Said control means is advantageously a double-acting or electric fluid cylinder arranged under the seat, connected on the one hand, to the latter and on the other hand, to the backrest at a point close to its lower end.
a double-acting gas spring it will be necessary to assist the movement. To obtain the relaxation position, it will naturally be necessary to lean on the backrest, but the muscular effort involved in compressing the jack will be low due to the favorable lever arm. The return to the seated position will be done by releasing the backrest.
the contact of the backrest with the cam profile can be established by rollers rolling on the latter or by sliding shoes on the latter.
rollers rolling on the latter or by sliding shoes on the latter.
the movement of the end in contact with the cam profile, rollers in particular will be carried out in a guided manner and for example on a slide with upper retainer so as to avoid any tilting of the chair forward on the axis seat.
the armchair according to the invention comprises a backrest 1, a seat 3, a footrest 5 and a support frame 7.
a backrest 1 In FIG. 2, only the planes of the backrest elements, seat are shown and footrests which can be materialized by their rigid support frames.
the footrest 5 is rotatably mounted on the seat, being articulated at its front end by an axis 9.
the backrest is articulated rotatable at the rear end of the seat by an axis 11.
a link 13 connects the file to the footrest, being articulated by its ends on each of them.
All of these three planes thus connected are mounted on the support frame 7. It is articulated at the front by the seat plane on a transverse axis 15 secured to the support frame and comes to bear at the rear by the 'lower end of the backrest on a cam profile 17 also fixed to the support frame. Said transverse axis of articulation, connected to the seat plane, is disposed slightly at the rear of its transverse median plane.
the lower end of the backrest includes rollers 19 engaging in rolling motion on the cam profile. These rollers roll in a slide conforming to the cam profile and are retained at the upper level by the slide to prevent any tilting of the chair forward.
An electric actuator 21 (or gas) disposed under the seat, connects the latter to the backrest.
This cylinder is articulated by its ends, respectively on the front part (limited to the axis 15) of the seat and on the lower part close to the end of the backrest. It is controlled by the seat user from an easily accessible lever in the rest position so as to shorten or lengthen its travel as desired, thereby moving the end rollers of the backrest on the cam profile between two positions d 'stop limits.
the rear limit position 23 corresponds to the sitting position (FIG. 2) and the front limit position 25 to the lying position (not shown) in which in particular the seat and back planes come in continuity with one another along a substantially horizontal line. In the intermediate positions of rest or relaxation, the rollers circulate in a variable manner on the cam profile thus authorizing a multitude of possible positions.
the seat plane is also mobile and that it tilts according to the stroke of the jack. This inclination also depends on the shape of the cam profile and its positioning on the support frame as well as on the positioning of the axis 15 on the support frame.
the seat tilt is designed to prevent the body from sliding on the seat in the relaxed position. In this or these positions it tilts backwards thus ensuring good retention of the body. It is also possible to provide a possibility of varying the positioning of the front transverse articulation axis 15 on the side of the seat, for example by a quick snap system allowing variations in the inclination of the seat, variations also depending on the cam profile chosen.
the displacement of the lower end of the backrest on the cam profile can be done by adherent rolling (on toothed profile) of the backing rollers , on the cam profile, these rollers being set and controlled in rotation by the operator.
