Description

The present invention relates to a device for relieving and

  comfortably maintain the back of people in a seated position, eliminating the movement that may exist between the back and the back of the

  seat, cause of discomfort and various ailments.

  To date there are available to relieve or maintain the back, lumbar belts, corsets, shells, specially shaped files, special covers. In all cases, the device is always either: dependent on the person, or: dependent on the backrest, so that the movement between the two cannot be suppressed, source of body compaction, shaking coming from the bottom up, repeated distances in the back, lateral oscillations, flexing of the shoulders and spine,

  fall forward, "whiplash" effect by rear impact in vehicle.

  The device according to the invention overcomes these drawbacks.

  It is composed according to a first characteristic of two parts

inseparable.

  The first part is made up of male or female gripping ribbons fixed vertically or horizontally on the fabric of the front of the seat backrest to make the seat or fixed on the front of a shell or half-shell of rigid material or semi-rigid or fixed on a removable cover k 20, of shape and size allowing its easy, fast and

solid on all issues.

  The second part consists of a vest of different sizes with t or sleeveless, it has on the outside of the back, securely attached

  male gripping ribbons arranged horizontally.

  The waistcoat closes with a wide crossover which has hook-and-loop ribbons

  female pants fixed horizontally on the front face of the internal part ij of the crossing and male gripping ribbons fixed vertically on the internal face of the external part. The closure is completed with a belt

  adjustable chest and clamping legs attached to its base.

  The cover is attached to the backrest using vertical straps

  wedges which go around the entire file. They are each provided, at one of their free ends, with a tightening loop. The part of the straps,

  | i attached to the inside of the front of the cover serves to reinforce the

  external gripping tapes. To prohibit the rotation of san-

  gles around the backrest, these according to one embodiment, each form at the top corner of the back of the backrest, ie: a loop in

2 2787399

  which is incorporated an individual or common slat to the straps, either:

  includes a connection to a loop of individual or com- plex material

mune with straps.

  Ii_ According to another embodiment, these are each provided, before their end, with a second strap and with a second loop, the end of the second strap passes behind a rigid rod forming part of

  the seat frame and then fix in the second loop.

  The front of the seat back trimmed with attached male gripping ribbons

  directly, or through the straps or a cover or a

  that or a half-shell, can be covered with a removable neutral-textured fabric in order to annihilate the gripping effect of the ribbons for people

disinterested in the device.

  The back side of the cover opens and closes with hook and loop tapes

males and females.

  The person wearing the waistcoat, sits down and leans on the backrest while presenting

  both the upper part of his back at a chosen height. In contact with the different

  rente structures of the gripping ribbons, the fixing being carried out, the person will remain in this chosen position, until his will to separate from the file; the higher the position will be chosen, the lower the body part

will be relieved.

  The so-called "whiplash" effect by rear impact caused by the separation

  The violent shoulder-to-back action is attenuated in its inertia by the braking caused by the separation of the male / female gripping ribbons, reducing until after eliminating, depending on the intensity of the shock, the consequences that

can endure people.

  According to a particular embodiment, the vest may include fractionated shoulder pads for adjusting the adjustment, they comprise

  male and female gripping ribbons.

  Male or female gripping tapes can be attached directly

  on the backrest during the manufacturing of the seat.

  Male or female gripping tapes can be attached directly

  on the fastening straps without the cover which becomes superfluous in this case.

  Male or female gripping ribbons can be attached to the san-

gles constituting a harness.

  Male or female gripping tapes can be attached to a half

  shell in rigid or semi-rigid material, matching the front of the backrest.

  Male or female gripping tapes can be attached to a shell

  in rigid or semi-rigid material matching the entire file.

  In all cases, the arrangement of the gripping tapes can be reversed.

  placed in the horizontal / vertical direction and in their male / female structure.

  The surface of the gripping ribbons can be more or less significant,

  depending on the destination or desired function of the device, for example: a person

  elderly or disabled who, by drowsiness, moves away from his backrest until risking a fall, will require more gripping surface than a person

  steering wheel of his vehicle, which should in principle for good driving, move away

voluntarily gain steering wheel.

  E male gripping tapes (5) fixed vertically and tightening tabs

attached to its base (12).

  According to Figure 3 the vest closes with a wide crossing which

  carries female gripping ribbons (2) fixed horizontally on the face

  front of the internal part (7) and fixed male gripping tapes (5)

  tically on the internal face (9) of the external part (10). The closure

  of the waistcoat is completed by an adjustable belt (11).

  The shoulder pads of the vest are split (8); they include ru-

  female and male grippers. According to FIG. 8, the cover is fixed to the backrest by vertical straps (13) which go around the backrest and are each provided at one of their free ends with a tightening loop (14). The part of the straps fixed inside the front face of the cover, serves as reinforcement for the fastening of the gripping tapes. The back side of the cover opens and

  closes with female (2) and male (5) gripping ribbons.

  To prevent the straps from rotating around the backrest, they follow

  vant an embodiment, each form at the top corner of the back of the backrest (15), either: a loop (16) in which is incorporated an individual slat (17) or common to the straps (18) fig. 4, either: a connection to an individual rigid loop (19) or common to the straps (20) fig.5.
