Description
DESCRIZIONE DESCRIPTION
dell'invenzione avente per titolo: of the invention entitled:
"Dispositivo di movimentazione di un supporto lombare in sedie? "Moving device for a lumbar support in chairs?
La presente invenzione concerne un dispositivo di movimentazione di un supporto lombare in sedie. The present invention relates to a device for moving a lumbar support in chairs.
Sono note sedie provviste di schienali sagomabili la cui caratteristica consiste nell?effettuare il sostegno della spina dorsale dell?utente in modo da mantenerla in una corretta posizione per lunghi intervalli di tempo. Chairs provided with shapeable backrests are known, the characteristic of which consists in supporting the user?s backbone so as to keep it in a correct position for long intervals of time.
In particolare queste tipologie di sedie presentano dei supporti a contatto con la regione lombare dell?utilizzatore quando questo si trova in posizione seduta con la schiena appoggiata allo schienale. In particular, these types of chairs have supports in contact with the lumbar region of the user when he is in a sitting position with his back leaning against the backrest.
Gli attuali dispositivi di regolazione presentano l?inconveniente di una difficoltosa e laboriosa regolazione per ottenere la posizione desiderata. Current adjustment devices have the drawback of a difficult and laborious adjustment to obtain the desired position.
Scopo dell?invenzione ? di eliminare questi inconvenienti e di realizzare un dispositivo di movimentazione di un supporto lombare di una sedia che presenti una semplice realizzazione. Purpose of the invention? to eliminate these drawbacks and to produce a device for moving a lumbar support of a chair which has a simple embodiment.
Tutti questi scopi ed altri che risulteranno dalla descrizione che segue sono raggiunti secondo l?invenzione con dispositivo di movimentazione di un supporto lombare in sedie come descritto nella rivendicazione 1. All these objects and others which will result from the following description are achieved according to the invention with a device for moving a lumbar support in chairs as described in claim 1.
La presente invenzione viene qui di seguito ulteriormente chiarita in una sua preferita forma di pratica realizzazione riportata a scopo puramente esemplificativo ma non limitativo con riferimento alle allegate tavole di disegno in cui The present invention is hereinafter further explained in a preferred embodiment thereof, shown for purely exemplifying but non-limiting purposes with reference to the enclosed drawings in which
Le figure 1 e 2 rappresentano il dispositivo nella posizione di massima e minima escursione Figures 1 and 2 show the device in the maximum and minimum excursion position
La figura 3 mostra il particolare del poggiareni Figure 3 shows the detail of the lumbar support
La figura 4 mostra la lamina Figure 4 shows the foil
Le figure 5, 6 e 7 mostrano i particolari del dispositivo. Figures 5, 6 and 7 show the details of the device.
Come si vede dalle figure il dispositivo di movimentazione del supporto lombare secondo l?invenzione comprende sostanzialmente un poggiareni 2 (supporto lombare) in materiale plastico a forma sostanzialmente rettangolare provvisto di due appendici 4 sulle quali sono ricavate delle sedi 6 a forma di toppa di chiave che vanno ad impegnarsi su dei perni cilindrici 8 ricavati su di una lama 10 flessibile sostanzialmente rettangolare. I bordi laterali della lama flessibile 10 si impegnano nelle sedi formate da guide verticali ad L 12 ricavate sulla parete 14 dello schienale 16 As can be seen from the figures, the device for moving the lumbar support according to the invention substantially comprises a substantially rectangular shaped plastic lumbar support 2 (lumbar support) provided with two appendices 4 on which seats 6 in the shape of a keyhole are obtained which engage on cylindrical pins 8 obtained on a substantially rectangular flexible blade 10. The lateral edges of the flexible blade 10 engage in the seats formed by L-shaped vertical guides 12 obtained on the wall 14 of the backrest 16
Il bordo inferiore della lama 10 si prolunga in due lamelle 18 solidali ad una maniglia sagomata 20. The lower edge of the blade 10 extends into two blades 18 integral with a shaped handle 20.
Le due lamelle 18 sono alloggiate in due corrispondenti scanalature 22 formate da quattro nervature 24, previste su di una porzione ricurva 26 solidale al bordo inferiore dello schienale, e vincolanti lateralmente lo scorrimento delle lamelle The two slats 18 are housed in two corresponding grooves 22 formed by four ribs 24, provided on a curved portion 26 integral with the lower edge of the backrest, and laterally constraining the sliding of the slats
L'invenzione prevede altres? impiego di un carter 28 di copertura della porzione ricurva 26 dello schienale avente la funzione di vincolare lo scorrimento verticale delle lamelle 18 alloggiate fra le nervature 24 dello schienale e le nervature 25 interne del carter 28 ed ? interessato da due feritoie 30 lungo le quali scorre la parte centrale della maniglia 20 Does the invention also provide use of a casing 28 to cover the curved portion 26 of the backrest having the function of constraining the vertical sliding of the slats 18 housed between the ribs 24 of the backrest and the internal ribs 25 of the casing 28 and ? affected by two slots 30 along which the central part of the handle 20 slides
In particolare la maniglia 20 presenta le estremit? 32 sagomate ad L per favorirne la prensilit?. In particular, the handle 20 has the ends 32 L-shaped to facilitate grip.
Il funzionamento del dispositivo di movimentazione del supporto lombare prevede che l?utente, una volta seduto sulla sedia, azioni la maniglia 20 che, tramite la lama flessibile 10 che scorre fra le scanalature 22, fa salire o scendere il poggiareni 2 fino a posizionarlo nella desiderata configurazione, e questo grazie alla flessibilit? delle lamelle che trasformano il loro moto curvilineo lungo la porzione ricurva 26 in moto lineare della lama nella zona dello schienale. The operation of the lumbar support movement device foresees that the user, once seated on the chair, activates the handle 20 which, by means of the flexible blade 10 which slides between the grooves 22, makes the lumbar support 2 rise or fall until it is positioned in the desired configuration, and this thanks to the flexibility? of the slats which transform their curvilinear motion along the curved portion 26 into linear motion of the blade in the area of the backrest.
