Abstract: Parking brake, in particular for a wheelchair, with a pressing element (10) articulated by a pivoting lever (8) coupled to a retainer (12) mounted to the wheelchair frame. The pivoting lever (8) is tiltable by swiveling a hand brake lever (7) into an engaged position, in which the pressing element (10) exerts force against a wheel (2). In addition, a resetting-force-applying element is set under a pre-load against the pivoting lever (8) to return the pivoting lever (8) to a neutral position when the hand brake is released, characterized by the fact that the resetting-force-applying element is a flexible bendable element (6) formed from a frame cover (5) fastened to the retainer (12).
Abstract: A stand-up wheelchair with a chassis, at which two drive wheels and at least a one guidable wheel is fastened, on which a stand-up unit with a seating surface, a backrest and at least one tiltable footrest is arranged, whereby reciprocally underneath the seating surface an upper longitudinal rail and a lower longitudinal rail are arranged, the upper longitudinal rail is firmly connected with the seating surface and both longitudinal rails are connected over four hinge points with their rear ends connected with a backrest, characterized by the fact that the rear ends of the longitudinal rails show a slot, in which the backrest can be longitudinally adjusted with their lower ends.
Abstract: A stroller, in particular a rehabilitation stroller, having a front frame which extends upward to the rear, at an angle <90° to the ground and has two front frame struts, which are directed forward and downward and are equipped at their respectively lower ends with front wheels, and has a push bar at its rear, upper end, and having a rear frame which extends downward to the rear and is fastened at its upper end to the front frame and/or to the push bar thereof and is equipped at its rear, lower end with rear wheels. In order to obtain optimum shock absorption for the child and optimum maneuverability of the stroller, the latter comprises, according to the invention, a frame construction which serves as a seat carrier or is actually part of a seat, is guided in a longitudinally displaceable manner on the two front frame struts and is supported with respect to the front frame struts on at least one spring bearing, the spring force of which can be adjusted.
