Abstract: The invention relates to a clamping device (1) for fixing a wheelchair drive unit to a wheelchair frame. The clamping device (1) comprises a lever element (4), a first clamping jaw (2), a second clamping jaw (3) and a clamping jaw holder (5). The first clamping jaw (2) and the second clamping jaw (3) are movably mounted on the clamping jaw holder (5) via a jaw path (D0-D2) between an open position (D0) and a closed position (D2). The lever element (4) is movably coupled to the first clamping jaw (2) and the second clamping jaw (3) via a lever path (SH) such that a movement of the lever element (4) along the lever path (SH) causes the clamping jaws (2, 3) to move along the jaw path (D0-D2).

Abstract: A folding wheelchair is disclosed having a frame with two side portions, a seat and a folding mechanism. The folding mechanism has coupling connections, pivoting connections and a cross-strut with two bars crossing at a pivot point. First ends of each of the cross-strut bars are mounted rotatably on the side portions of the frame via the pivoting connections. Second ends of each of the cross-strut bars are releasably mounted on the other of the two side portions of the frame via the coupling connections. A distance between the frame side portions may be modified if the cross-strut bars second ends are released from the frame side portions. The cross-strut bars are pivoted relative to each other about the pivot point. The cross-strut extends from the first ends to the second ends of the bars in a cross-strut direction which, in the operating position, extends substantially along the seat.

Abstract: A drive device (1) for a wheelchair (2) comprises a control element (23), a chassis (9, 13) and a support frame (15). A fixing arrangement (19) is mounted on the support frame (15) and can be fixed to a wheelchair frame (7) of the wheelchair (2). The fixing arrangement (19) is designed such that it can be automatically connected to and released from the wheelchair frame (7) of the wheelchair (2) by a fixing drive (21).

Abstract: The present invention relates to a foldable wheelchair (10) comprising two side frame components (11a, 11b), respectively a left and a right side frame components, each mounting front and rear wheels (12a, 13a; 12b, 13b), respectively left and right, front and rear wheels, said rear wheels (13a, 13b) having an axis of rotation (XX?), said side frame components (11a, 11b) being connected together for relative folding movement between an erected position and a folded position by foldable link element (20) extending between said two side frame components (11a, 11b), wherein the left, respectively the right, side frame component (11a, 11b) comprises a T-shaped bracket (17), along which is connected both a rear wheel suspension (19) of the left, respectively the right, rear wheel (13a, 13b) and a left, respectively a right, end (21a, 22b) of the foldable link element (20), wherein the position of T-shaped bracket (17) is adjustable along the back-to-front direction of the wheelchair so as to permit the adjustment

Abstract: A wheelchair (10) comprising:—a seat module (10) including a seat frame (11) supporting a seat (12);—a backrest module (20) including a backrest frame (21) connected to said seat frame (11) and supporting a backrest (22);—a front frame module (30) including a front frame (31), said front frame (31) including left and right bended legs (31a, 31b) removably connected at their upper end to said seat frame (11) and at their lower end to a footrest (32), said bended legs (31a, 31b) being supported by caster wheel assemblies (35, 36) via caster support (34);—a rear wheel module (40) including left and right rear wheels (41a, 41b) pivotally connected to an axle (42), said rear wheel module (40) being removably connected to said seat module (10) through left and right connecting elements (43a, 43b); wherein said seat frame (11) consists in left and right longitudinal profiles (11a, 11b) extending in the same plane.

Abstract: The wheelchair comprises a seat and two main wheels connected by an axle. A support device, comprising an exchangeable intermediate element consisting of an elastomer element located in the lacuna provided by the spiral turns of a spring, is detachably fixed at one of its end to a chassis of the seat and at its other end to the axle through a center part attached to the middle part of the axle. The center part is arranged to receive the rear ends of the two left and right main frame tubes of the wheelchair.

Abstract: The parking brake can be fitted to the wheelchair frame largely regardless of the nominal position of the brake element, and conversely the position of the brake element can be exactly matched to the position of the rear wheel. A two-piece clamp connects a cylindrical bearer to a part of the wheelchair frame and allows the bearer's rotation and lengthwise displacement relative to the frame. One end of the bearer holds the pivoting brake element and locking lever. One arm of the locking lever acts together with the brake element and has two recesses. When the locking lever is moved to a released position, spring action forces the brake element to engage one of the recesses and to be located beside the rear wheel approximately perpendicular to the wheel's rotational axis. When the locking lever is moved to a braking position, the brake element engages the second recess and is located more or less parallel to the rotational axis of the rear wheel.

Abstract: A foldable wheelchair, which may be moved along a predetermined direction of movement, includes first and second side frames, drive wheels and travelling wheels rotatably supported on the side frames, and a folding mechanism which extends between the side frames, which can be moved between a folded position and an unfolded position, and which, in turn, includes first and second pivoting devices. Each pivoting device may be pivoted about a respective center axis, which extends approximately along the direction of movement, and each pivoting device has ends facing away from its respective center axis. Each side frame defines first and second pivot axes, which extend substantially parallel to the center axes. The ends of the first pivoting device are pivotable about corresponding of the first pivot axes, and the ends of the second pivoting device are pivotable about corresponding of the second pivot axes.
