Definitions

  • the present invention relates to a seating arrangement, adjustable, especially for the elderly.
  • the seats used in particular for sitting in front of a table include feet, a seat and a backrest.
  • the angle between the seat and the backrest largely contributes to the comfort of the user, it is studied and must be preserved.
  • the seats concerned are fixed-seat seats, particularly used for elderly people in nursing homes or retirement homes but which could also be used as a family.
  • the seat is generally attached to a frame itself supported by the feet, this seat being fixed to the frame in a non-movable manner.
  • Such chairs can not include mechanisms requiring adjustment tools, which could lead to complex adjustment manipulations and even less movements that could cause injury.
  • the adjustment time must also be of a certain speed because when the time comes, during meals for example, it is necessary that the staff possibly involved can adjust the height quickly, the occupations at that time being multiple.
  • a chair 10 which comprises a frame 12 for receiving a seat 14, four feet extending from said frame to the ground and a backrest 16 extending from said frame in the opposite direction.
  • the two back legs and the backrest can be monolithic for these chairs, this being only a constructive option, these options not being part of the present invention.
  • the seat 14 and the backrest 16 have an open angle of inclination, for example 95 ° to give an order of magnitude for a chair for use at the table.
  • the seat 14 is a seat support 18, generally ergonomically shaped, having a slight hollow in the central part, covered with a coating of any kind, fabric, wood or plastic, with or without interposition of a material of comfort such as a foam.
  • This seat support 18, comprises at least two cross members 20-1 and 20-2, oriented transversely, that is to say parallel to the folder.
  • pin 22 is taken in its widest acceptance axis, and applies to any type of material. These pins may have come from manufacture with said sleepers, especially when these sleepers are made of wood.
  • the frame 12 has side uprights, right 24R and left 24L, if we consider a view of the seated user.
  • These lateral uprights 24R and 24L each comprise two tracks 26F front and rear 26R, four tracks for each receive one of the pins.
  • the front tracks have a general inverted U shape for the front runway 26F and a very open V shape, one of whose branches is horizontal, as can be seen on the figure 3 , for runway 26R.
  • the front track 26F comprises a horizontal branch 28 of the inverted U , the front end of which opens into the first vertical branch 30, short of a height h .
  • the second vertical branch 32 of the inverted U is vertical, long, a height H , the difference H - h being equal to D, the height differential between the high position and the low position of the seat.
  • the rear track 26R close to the backrest, open V , comprises a first horizontal branch 34 aligned with the bottom of the lower end of the first vertical leg 30, short of a height h .
  • the line XX 'passing through the centers C1, C2 is horizontal.
  • the second rear branch 36, of the open V is inclined and its end is aligned with the end of the second vertical branch 32 of the u vertical, long U , along the line YY '.
  • the distance T of minimum horizontal translation is equal to the distance between the two branches of the track 26F before, in U reversed.
  • step A the upper position of the journals 22 along the axis XX '.
  • the sleepers 20-1 and 20-2 therefore in the high position, the shell 18 secured to the sleepers is also in the high position and the seat 14 is actually in the high position. It is also noted that the seat 14 is in the forward position.
  • step B the operator raises the front of the seat, so that the trunnion 22 of the crossbar 20-1 is lifted along the first leg 30, short, while the trunnion 22 of the transom 20-2 stays in place.
  • step C the operator provides a rearward translation of the seat and, this time, it is the two journals that are driven backwards in the horizontal portion of the track 26F and in the inclined portion from runway 26R.
  • step D the journals 22 of the cross members 20-1 and 20-2 abut in the horizontal branch 28 of the track 26F and at the bottom of the second branch 36 of the track 26R.
  • the device addresses the issues raised simplicity of implementation, simplicity of implementation, limited manufacturing cost, removal of any risk of injury, comfort of all users with a simultaneous height adjustment and advance of the seat.
  • the embodiment that has been presented includes recessed tracks on the uprights and pins projecting from the rails but on other strictly similar arrangements the pins can be carried by the uprights and tracks by the seat.
  • the presentation targets applications with chairs usually made of wood for the intended applications but in the case of the use of plastics or metal, it is possible to position projecting tracks and pins in the form of pebbles without changing not the present invention.
