Problems solved by technology

[0007] However, despite the great convenience of transitioning to the two states of standing upright and sitting down, due to the height of the footrest and the low ground clearance, this seat sometimes passes the edge of the sidewalk when the user is sitting down. Problems arise when obstacles

Embodiment Construction

[0033] Such as figure 1 and 2 The upright seat according to the invention shown generally at 1 comprises a chassis 2 with motorized drive wheels 10 at the front and pivoting wheels 11 at the rear.

[0034] As shown, the chassis 2 corresponds to a seat of rigid design, however it is obvious that a foldable seat can also have a substantially similar construction. In fact, in this case (ie the case of a foldable seat), the rigid beams of the chassis are replaced by known foldable elements.

[0035] The aforementioned chassis 2 is equipped with verticalization means realized in the form of hinged structures 12 supported by the chassis 2 . The hinged structure 12 consists of lateral hinged systems located on both sides of the cushion A. figure 1 and 2 Only one of the articulation systems is visible in . Each articulation system 13 serves to adapt the chassis 2 laterally.

[0036] Each articulation system 13 comprises a first deformable polygon, according to the example a defo...

Abstract

Wheelchair comprises a footrest (R) with a support structure (26) that is suitable for allowing the footrest in the lowered or sitting position of the joint structure (12) to be varied in height. Preferred Features: The support structure has a second deformable polygon (27) connected to a chassis (2) and / or a first deformable polygon (17), a footrest bar or support (28) connected by a journal with a horizontal axis to the first polygon or to an element connected to a seat (A), and a rocker bar (50) arranged between the chassis and the footrest support and connected to the footrest support via a connection with a degree of freedom with regard to horizontal axial rotation and a degree of freedom with regard to a vertical displacement axis.

Description

technical field [0001] The present invention relates to seats used by disabled or handicapped persons, and also to manually or electrically driven foldable or non-foldable wheelchairs. [0002] The invention relates more particularly to so-called "vertical" chairs, which enable the user to be in a sitting or upright position. As described in French patent FR2769830, this seat consists of a chassis supporting an articulated structure, which includes a cushion, a footrest, a backrest, and two laterally symmetrical articulation systems that ensure that the backrest or the feet The verticalization-lowering function of the pad of the pedal to enable the user to transition from the seated position to the upright position. Background technique [0003] To this end, each lateral articulation system consists of a first deformable quadrilateral or polygon for supporting the underlayment, which polygon consists of two bars - an upper bar and a lower bar respectively, which are hinged ...
