Figure 2 is an enlarged view of the backrest ofFigure 1 , with some components in exploded view; -
Figure 3 is an exploded view of the backrest ofFigures 1 and2 ; -
Figure 4 illustrates a frontal perspective view of the backrest ofFigure 1 ; -
Figure 5 shows a rear view of the backrest; -
Figure 6 depicts a side view of the backrest. - The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
- In this document, the "outer portion" of the backrest or of the slot corresponds to the rear portion of the wheelchair; the "inner portion" corresponds to the portion against which the user back rests.
-
Figures 1 to 3 illustrate perspective views of thebackrest 1, showing the rear portion and part of the left side of the backrest. Abackrest plate 2, preferably made of plastic or other mouldable material provides the backrest active plane, that is to say the plane providing the surface against which the user back will be placed, in use. The main longitudinal axis X-X of thebackrest plate 2 is shown in the central portion of the backrest. - A
frame 7, cooperating with the bottom portion of a wheel chair, provides the required support for thebackrest plate 2. In the illustrated embodiment, theframe 7 is U-shaped, with its two extended legs serving as supports on which thebackrest plate 2 is slidably attached. At least one, and preferably two lateral trunk supports 4 are provided on each side of the backrest. On the upper portion of thebackrest 1, aneckrest 5 is attached to thebackrest plate 2 in a manner described hereafter. - As best seen in
Figure 5 , thebackrest plate 2 is provided with twolongitudinal adjustment slots 6, extending on each side of thebackrest plate 2. along an axis substantially parallel to the main axis X-X. Theseopen slots 6 provide slidable attachment of thebackrest plate 2 on theframe 7 and of thelateral trunk support 4, as further described hereafter. - To adjust the height of the
backrest 1, thebackrest plate 2 is movable along the X-X axis and may be secured in almost any position along theframe 7. Adjustment may be made in a very simple and quick way. When thescrew 31 andnut 32 arrangements are slightly loosened, that is to say enough to allow thebackrest plate 2 to slide against theframe 7, but not enough to allow complete removal of the latter, thebackrest plate 2 may be moved up and down and adjusted along a position allowing a maximum comfort for the user. Once an appropriate position is reached, thebackrest plate 2 is secured with thescrew 31 andnut 32 arrangements. These screw and nut arrangements allow securingclamps 3 simultaneously in theslots 6 and against theframe 7. In this way, the backrest is firmly held against theframe 7. The clampingarm 33 ofclamps 3 cooperates with theframe 7 and provides a tight fit relationship between the frame and the backrest plate when the screw and nut arrangement is tightened. The clamps are further provided with a leg, extending from the clamp to slightly penetrate into the slot, to enable easy sliding displacement. - The
slots 6 enable a very wide choice of potential positions. When theclamps 3 are placed in the upper section of the slots, thebackrest plate 2 may be lowered. When theclamps 3 are placed in the lower section of the slots, thebackrest plate 2 may be lifted. To enable an extreme lifted position, theclamps 3 and the lateral trunk support holder member 41 (described hereafter) may be exchanged, so that thesupport holder member 41 occupies the highest position. -
Additional clamps 3 may be provided in the lower portion of thebackrest plate 2, in a non slidable relationship with respect to thebackrest plate 2. These clamps may however be slided along theframe 7 when thebackrest plate 2 position is modified. In the illustrated example, these clamps are also secured byscrew 31 andnut 32 arrangements. -
Figures 1 ,4 and6 show the lateral trunk supports, comprising abody support 4, for direct contact with the user's body, atrunk support arms 42, extending from saidbody support 4 towards the rear portion of thebackrest plate 2, for attachment thereof. Thetrunk support arm 42 is slidably mounted into a lateral trunksupport holder member 41.Such holder member 41 is conceived to provide two degrees of freedom. First, it is slidably mounted intoslot 6 in a similar manner as the backrest clamps 3. It may thus be slidably displaced along the slot for selection of the most appropriate position to provide a best support and comfort to the wheelchair user. Screws 44 (seefig. 3 ) anddual nut arrangement 45 secure theholder member 41 along the slot. Secondly, aholder slot 46 is provided in theholder member 41 and is oriented substantially transversal to main axis X-X, so as to provide lateral adjustment of thetrunk support arms 42. Ascrewable securing member 43 enables securing the support arm into holdingmember 41. Unscrewing the latter allows lateral displacement, to adjust the lateral position of thelateral trunk support 4. Once proper positioning is reached, the securingmember 43 may be tightened. - As shown in
Figures 2 ,3 and5 , thebackrest plate 2 is further provided with aneckrest attachment structure 54 comprising a neckrest attachment andadjustment channel 52. The channel is oriented substantially parallel to said main axis X-X and has its opening in the upper direction, to enable insertion of theneckrest attachment arm 51. Thechannel 52 is shaped as an extended tunnel, allowing slidable displacement of theneckrest attachment arm 51 along the channel axis, enabling height adjustment of theneckrest 5. Once the optimal position is reached, securingscrew 53 allows securing the neckrest attachment arm in place, until further adjustment is required. The neckrest attachment structure is preferably integrally molded together with thebackrest plate 2. -
Figure 4 shows the inner portion of thebackrest plate 2. This view allows showing the inner portion of theadjustment channel 52, with theneckrest attachment arm 51 placed therein. An Allenkey holder 8, molded together with thebackrest plate 2 enables safe storing of the tool required to screw/unscrew important components of the chair. Storing the tool therein avoids loosing it, ensuring its availability in any circumstance. -
Figure 4 also illustrates a set of wire hooks 9 that may be used for wire or cable attachment purposes. - Although not shown in the Figures, the
backrest 1 is preferably covered with foam or other soft material to provide more comfort for the user. A covering may also be provided. - The above detailed description with reference to the drawings illustrates rather than limit the invention. There are numerous alternatives, which fall within the scope of the appended claims. For instance, the clamps and holder members are shown with screws and nuts. Other types of fastening means may also be used without departing from the invention.
- The word "comprising" does not exclude the presence of other elements or steps than those listed in a claim. The word "a" or "an" preceding an element or step does not exclude the presence of a plurality of such elements or steps. The mere fact that respective dependent claims define respective additional features, does not exclude a combination of additional features, which corresponds to a combination of dependent claims.
