Embodiment Construction

[0046] The object of the present invention is to allow the user to adjust the inclination of the seat back of an upright wheelchair, such as shown in FIGS.

[0047] This wheelchair 1 comprises a frame 2 consisting of two transverse half-frames 3 and 4 interconnected by transverse bars 5 and 6 . These various structural elements define a frame provided with motorized wheels 10 and deflected wheels 11 .

[0048] As shown, the frame 2 corresponds to a wheelchair of rigid design, but it is obvious that a substantially similar design can also be applied to a collapsible wheelchair. In fact, in this case the rigid crossbars 5 and 6 can then be replaced by foldable elements known per se.

[0049] As mentioned above, the frame 2 is equipped with a verticalization means which is the hinged structure 12 carried by the frame 2 . The articulation structure 12 comprises at least one—according to the embodiment shown, exactly one—deformable quadrilateral 13, which quadrilateral Figure 4...

Abstract

The invention relates to un stand-up wheelchair for handicapped people and invalids, comprising a frame ( 2 ) supporting a hinged structure ( 12 ), supporting a seat back (D), a seat (A), a footrest (R) and being mobile between a seated position (P 1 ) and an upright position (P 2 ), characterised in that the hinged structure comprises a hinged support system of the seat (A) and of the seat back (D) which comprises at least an upper side rail ( 14, 15 ), a lower side rail ( 35 ) and front ( 27 ) and rear ( 20 ) spacers carrying a seat back upright and manoeuvring means ( 50 ) which are interposed between the frame ( 2 ) and the lower side rail ( 35 ) and which are adapted, by displacement of the lower side rail, on the one hand, to ensure adjustment of the inclination of the seat back upright ( 24, 25 ) when the upper side rail ( 14, 15 ) is supported on a seat bearing ( 52, 53 ) and, on the other hand, to verticalise the hinged structure ( 12 ) when the front spacer ( 27 ) has reached its maximum return position.

Description

technical field [0001] The present invention relates to seats and in particular but not exclusively to wheelchairs for use by handicapped and handicapped persons, the invention relates to foldable or non-foldable wheelchairs. Background technique [0002] Undoubtedly, wheelchairs offer the possibility of mobility to the handicapped and handicapped. However, these wheelchairs have a number of disadvantages since the user can only occupy one sitting position, and they usually remain in it for a long time. [0003] This state can no longer be adapted to everyday life and is not conducive to contact with society. In addition, this long-term sitting posture is likely to cause physical decline, such as reduced range of motion angles of lower appendages, blood circulation disorders, slowed digestion and gastrointestinal functions, and osteoporosis. [0004] In order to eliminate the above disadvantages, there has been proposed a wheelchair whose frame supports a hinged structure ...
