Abstract: A wheelchair including a chassis, two front suspension arms connected by a pivot link to the chassis and by a pivot link to a support assembly of a front wheel, two rear suspension arms connected by a pivot link to the chassis and by a pivot link to a support assembly of a rear wheel, and connecting means arranged to connect one of the front suspension arms to one of the rear suspension arms and to convert each rotational movement of the front suspension arm with respect to the chassis into a reverse rotational movement with respect to the chassis of the rear suspension arm to which it is connected by the connecting means, and vice versa.

Abstract: A steering mechanism comprising a first swing bar (1) with a first link (12) designed to allow the swing bar (1) to pivot about an axis of rotation (z). A second link (13) collaborates via a second pivot (23) with a first member (33) collaborating with a first wheel (43), and a third link (14) collaborates via a third pivot (24) with a second member (34) collaborating with a second wheel (44). The second link and the third link are positioned symmetrically. A fourth link (15) is designed to be able to collaborate via a fourth pivot (25) with a linear actuator (4). The fourth link is offset from said central axis so that actuation of the linear actuator (4) causes the swing bar to rotate, and causes a rotation of the wheels (43, 44).

Abstract: A wheelchair including a chassis, two front suspension arms connected by a pivot link to the chassis and by a pivot link to a support assembly of a front wheel, two rear suspension arms connected by a pivot link to the chassis and by a pivot link to a support assembly of a rear wheel, and connecting means arranged to connect one of the front suspension arms to one of the rear suspension arms and to convert each rotational movement of the front suspension arm with respect to the chassis into a reverse rotational movement with respect to the chassis of the rear suspension arm to which it is connected by the connecting means, and vice versa.

Abstract: According to the invention, the wheelchair is characterized in that it includes means to incline the whole seat structure, and inclining means that are interposed between the chassis and the lifting means and that include at least: a base (65) that is attached to the chassis (1) and that oscillates around a more-or-less horizontal axis, and on which the lifting means are fitted, and a mechanical assistance means that is interposed between the base (65) and the chassis (1) and that is designed to allow modification of the slope of the whole seat structure by rotation of the base (65).

Abstract: Steering mechanism for orienting the steered wheels (1a-d) of a short vehicle with respect to the chassis, comprising one first vertical axis (2) per steered wheel, allowing each steered wheel (1a-d) to pivot with respect to said chassis and a first link (5a-d) allowing a torque to be applied to each steered wheel to make it pivot around said first vertical axis. The inner end of the link is able to slide along a straight rail (11a-d) which in turn is rotatably mounted with respect to the chassis 60. A second link (6a-d) not parallel to the wheels forces the first link (5a-d) to slide in a defined manner along a rail (11a-d). This makes possible the differentiated orientation of the left and right wheels. Advantage: very small turning radius. Particularly applicable to electric chairs for the disabled.

Abstract: The invention concerns a standing wheelchair for handicapped and invalid people, that includes a chassis supporting an articulated structure which includes a seat support structure, a footrest support structure, a backrest support structure, and support and maneuvering resources of the articulated structure. The support and maneuvering resources are located between the articulated structure and the chassis and which are designed to move the articulated structure from a sitting position to a standing position set back in relation to the sitting position, and vice versa. According to the invention, the standing wheelchair includes resources for setting the angle (?) between the footrest and the seat in the standing position.

Abstract: The invention relates to a 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 (P1) and an upright position (P2), characterized 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 maneuvering 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 verticalize the hinged structure (12) when the front spacer (27) has reached its maximum return position.

Abstract: A wheelchair including a chassis (2) and an articulated height adjustment structure (12) with a seat, foot rest and back is disclosed. The articulated structure is made up of two symmetrical and lateral articulated systems, each having a first folding quadrilateral (17) with upper and lower bars (18, 19), pivoted at the front to the chassis and at the back by a spacer (20), and a second folding quadrilateral which helps to support the foot rest and connects the chassis at the front to the first quadrilateral. Each spacer is in the form of a triangular plate connected to the upper and lower bars (18, 19) by fixing nuts which can be set in adjustable positions on the bars. The spacers on opposite sides of the wheelchair are connected by a crosspiece.

Abstract: A chair for the handicapped or invalids. In the chair the second assembly is disposed at least in part behind the front plane and is linked to the first assembly by at least one reversible actuation and coupling rod, itself set back from the front plane and beneath the plane defined by the seat in its low position.
