Definitions

• Postural balancing device using dynamic supports of the human body recovering the weight of elements or body segments to support others by means of mobile surfaces synchronized mechanically or by any other suitable system, and acting by leverage , in particular a seat based on this principle.
• the present invention relating to an active support device for the human body has as a principle the mobilization of a first support, actuated by the weight of a body segment causing in its movement, by a linkage in particular mechanical, a second support, supporting, by leverage, another body segment.
• the present device sees its main embodiment in a seat with variable geometry and all types of seats (standard furniture seats, folding seats, camping or beach seats, car seats, seats for public transport and all other vehicles, seats hairdresser, performance hall seats, seats for medical use, by way of non-limiting examples).
• An existing blocking system can be adapted on this type of seat, either by blocking the seat or the backrest, or by blocking the transmission system between the backrest and the seat, separately or jointly.
• a braking system roller, disc, inertia using springs or weights, as non-limiting examples, especially in the case of the vehicle seat
• variable ischio-lumbar seat The principle of the variable ischio-lumbar seat is to recover the sliding force of the ischia on the mobile seat and to communicate it to the backrest, itself pivoting to which it is secured by means of a strap passing over a roller, or by any other means of joining, mechanical or not ”
• the backrest then acts as a lever, moved indirectly by the movement of the seat.
• This seat thus respects the basic ergonomic principles and realizes a permanent take-up of the lumbar support, whenever the trunk rests on the backrest.
• connection system securing the seat and the backrest may be constituted by a strap (of the seat belt type) having a coefficient of deformation and elasticity as low as possible, passing on a roller or any other transmission system.
• a strap of the seat belt type
• the seat can also slide on one or more fixed rails, curved or not, or be moved by pressure or by weighing or any other system.
• Suitable materials are those of common type for the manufacture of all seats, but it is preferable that the seat is covered with non-slip upholstery fabric, ensuring good grip.
• the base can be metallic, wooden, plastic or other material, of various shapes, with single or multiple legs.
• the whole seat can be foldable or not.
• FIG. 1 shows a profile diagram of the seat with variable ischio-lumbar support.
• the mobile seat (1) pivots about an axis, preferably fixed (2), slides on rails (10) (fig. 2) or is moved on rollers or rollers (17) (fig. 3) and communicates the sliding force to the backrest (3), itself pivoting about an axis, preferably fixed (4).
• the movable backrest and seat are joined together by means of a flexible but non-elongable transmission system (5) passing over a roller or a pulley, preferably fixed (6).
• FIG. 2 represents a variant for a vehicle seat. In this variant, the seat (1) slides on one or more rails (10).
• the upper part of the backrest (7) being fixed, the mobile part of the backrest (3) responding to this device has, on either side of its pivot axis (4), a lower part (8) playing the role of dynamic lumbar support and an upper part (9), internal to the frame of the backrest (7) and only acts as a purely mechanical lever arm.
• Figure 3 shows, according to the same principle, a device of articulated cushions to be placed on a common chair to improve comfort.
• the mobile seat (1) moved on casters (17) communicates the sliding force to the backrest (3), fixed on a spacer (18) pivoting around a fixed axis (4).
• the backrest and seat are joined together by means of a flexible transmission system (5) passing over a roller or a fixed pulley (6).
• Figure 4 shows the general device, which can be used in various dimensions as back rest, headrest, armrest (for example).
• the support (1) actuated by an element or body segment drives, by the transmission mechanism (5, 6) the support (3) which dynamically supports another element or body segment such as back, head, forearm, for example), by pivoting on an axis (4).
• FIG. 5 represents another variant which uses a semi-cylindrical rocker base (11) at one end of which the support (backrest) (3) is fixed and at the other end the mechanical transmission (strap) (5) which passes through an opening (12) made in the support (backrest) (3) and extends to the support (seat) (1) to which it is secured.
• FIG. 6 represents a camping flask or a briefcase or any other utility object (in particular beach or camping), in particular made of plastic, serving as a headrest or back rest (3 ) (for the beach, camping or any other use). It has a semi-cylindrical base (11), an opening (12) which allows the passage in particular of a beach towel which serves as support (seat or backrest) (1) and which is blocked by an instant fixing system which whether it is (13), located at the rear of the gourd and whether or not passing through the opening (12).
• the flask has a screw thread neck (14), provided with a stopper (15) and possibly a handle (16).
• This body support device thus described can be applied to the following uses, by way of nonlimiting examples: common furniture seat, patient's chair (patients suffering from immobilization in complete straightness of an inferior member laughing, for example), which can be converted into a chair with an appropriate modification of the seat adaptation to the articulated head of a bed (for the sick, for example); back rest (allowing a patient to sit on the edge of his bed, for example); camping and beach equipment (back rest, headrest), based on the same principle or on the variant shown in Figure 5; mobile armrest with variable positions (to facilitate precise manual work of various professions).
• common furniture seat patient's chair (patients suffering from immobilization in complete straightness of an inferior member laughing, for example), which can be converted into a chair with an appropriate modification of the seat adaptation to the articulated head of a bed (for the sick, for example); back rest (allowing a patient to sit on the edge of his bed, for example); camping and beach equipment (back rest, headrest), based on the same principle or on the variant shown in Figure 5; mobile
