Definitions

  • the seat module - or saddle - essentially comprises a frame 10, a fork-shaped frame 12, a hinge 14 connecting, so articulated, the frame 10 and the fork 12, and an elastic membrane 16, visible only in Figures 3 and 4.
  • the saddle has a symmetrical structure with reference to a vertical plane passing through lines II-II of Figures 1 and 3.
  • the saddle according to the invention can advantageously be supplemented by a pad 32, forming a cushion, completely covering the membrane 16 and fixed thereto permanently or removable.
  • This cake can be made of a fabric envelope containing an elastic padding or formed of a gel.
  • it is provided with a longitudinal groove 34 extending over the entire length of the cushion. In this way, the coccyx of the saddle occupant is not compressed, which improves its comfort and makes it possible to avoid certain damage, in particular at the level of the spine.
  • FIG. 5 shows that the seat module previously described makes it possible to equip a seat formed with a support 36 which comprises, in known manner, a telescopic central column 38 and feet 40 arranged radially, each provided with a roller 42
  • the column 38 carries, at its upper end, a seat module 44 according to the invention, which is fixed by its frame 10.
  • a seat thus forming a stool, can advantageously be used by people working essentially in the "active" position, for example a dentist or a watchmaker. It can be completed, as shown in this figure, by a backrest 46 fixed to the cantle 26 and making it possible to take a "passive" position.
  • transverse support bar 48 for the knees, advantageously padded and covered with a fabric or leather, so that the contact is pleasant .
  • This bar is fixed to the support 36, permanently or removable, by means of an arm 50.
  • the latter has a wheel 42 and is advantageously pivotally or slidingly connected to the support 36, so that it can be retracted when the user often has to leave his seat.
  • the pressure of the knees against the bar 48 is low. It therefore does not participate very much in the sitting of the user. It prevents him, on the other hand, from crossing his legs, and thus, certain inconveniences associated with this habit. As can be seen in FIG.
  • the arm 50 is fixed to the support 36 in the vicinity of the feet 40, that is to say very close to the ground. In this way, it does not or hardly hinder movement when the user takes his seat or leaves it.
  • the seat module 44 can be mounted articulated on the column 38 by means of a conventional mechanism 52 of adjustable seat rocker from which an armrest 54 takes advantage. Thanks to the construction described, when the user sits down to put himself in the "active" position, he finds the saddle 44 automatically placed in the rest position corresponding to maximum comfort, that is to say with the femoral joint. vertical to the joint 14. If the user leans forward, the fork 12 will accompany his movement, allowing him to adjust his posture in a self-lift process which contributes to the strengthening of the lift musculature and thus tends to reduce the risks of health problems, as discussed above.
  • the seat according to the invention allows, in the "active" position, posture adjustments promoting the work of the self-supporting muscles, while in the "passive” position, these muscles can relax .
  • the knob 20 can also be provided means making it possible to modify its position with reference to the frame 10. It is also possible to envisage an asymmetrical structure, intended for a disabled user, either at the level of the pancake 32, or in the form of the cantle 26.
  • the articulated connection, by the hinge 14, between the frame 10 and the fork 12, can be ensured by means of a ball joint. In this case, the self-supporting mechanism will be carried out from front to back as well as from the side.
  • the position of the hinge 14 can also advantageously be adjustable in the front-rear directions, so that it is perfectly aligned with the ischia when the user is seated.
  • Other adjustment means are possible to vary the distance between the knob 20 and the cantle 26, in order to adjust the tension of the elastic membrane 16.
  • the saddle 44 is advantageously fixed to the support 36 by its frame 10. It is also conceivable to ensure the fixing by the cantle 26 itself.
  • the spring function provided by the elastic membrane 16 can also be reinforced by springs arranged specially for this purpose, for example torsion, traction or compression. Finally, it should be noted that it may be advantageous to provide the backrest 46 with an independent lumbar support area with disengageable permanent contact.
