Abstract: The inclinable leg rest device for a wheelchair having a wheeled frame to which a seat is attached includes a structure mounted pivotably on the frame in order for the user to be able to assume a position between two extreme positions of the legs being bent and the legs being straightened. The leg rest device also includes a board provided with pads for calf placement and slidably mounted on the pivoting structure so as to enable a lengthwise adjustment and an adaptation of the positioning of the pads. The board is slidably mounted on the pivoting structure through a curved guide path which is convex on the side that supports the legs.

Abstract: The telescopic inclinable footrest device for a motorized wheelchair includes a frame which pivots the structure of a legrest having a sliding plate. The structure is pivotably mounted so as to pivot between a deployed end position and a stowed end position. The pivoting and sliding the legrest are by a motor having a single cylinder rigidly attached to the structure and to the frame. A portion of the retraction stroke of the cylinder brings the structure into the stowed position while the extension of the retraction stroke of the cylinder generates the movement of a pulley borne by the rod of the cylinder over which passes a strap which connects the plate to the frame. The movement is suitable for shortening the path of the strap and thus deploying the plate.

Abstract: The present invention relates to an omnidirectional wheel including a central hub; and a tread peripherally mounted on the central hub. The tread includes the juxtaposition of wheels or sleeves arranged along radial planes. The wheel also includes spokes connected, two-by-two, via a shaft section. The shaft section is coaxial to the hub, which has a round cross-section, and onto which freely rotatable rings are fitted. The shaft section includes struts inserted between each ring and shaped such that rings remain in a radial position. The shaft section also includes a series of a plurality of abutting tubular segments. The invention further relates to a module for assembling an omnidirectional wheel.

Abstract: The device for crossing obstacles for a motorized vehicle includes a chassis connected to n (n?3) wheels on each side, and a driver suitable for rotating the wheels. Each side of the chassis includes a mechanism comprising n?1 arms hingedly connected two-by-two about a shared pivoting axis on which the n wheels are distributed, respectively a front wheel, n?2 intermediate wheels, and a rear wheel. The mechanism allows each wheel to pivot relative to the axis of each adjacent wheel.
