Abstract: A hospital bed (1) has a removable headboard (11). The removable headboard is provided with a handle bar (12), the free ends of which sit on the upper frame (4) of the lifter (2). In order to connect the handle bar to the lifter, inserting pins (22) are provided on the lifter. Said inserting pins are designed such that neither during insertion nor during removal of the headboard (11) from the inserting pins any clamping effect can occur.

Abstract: A treatment bed has two lifting motors connected in parallel mechanically in the height-adjustable lifter. In order to load the lifting motors evenly and avoid torsions in the lifter, a balancing circuit that measures the supply currents of the lifting motors is provided. If a difference is determined, then the respective current is briefly interrupted several times until the magnitudes of the currents approach one another.

Abstract: A wheelchair having a remote controlled electric drive system so that the user is able to move the wheelchair away or retrieve it without the assistance of another person. The electric drive system includes multiple safety features for precluding hazardous situations that result from accidentally or unintentionally setting the drive system in motion while the wheelchair is occupied.

Abstract: A height-adjustable nursing bed is provided that includes a pedestal in which the upper frame and the lower frame are connected to one another by a total of four toggle lever pairs. The toggle lever pairs on each side of the bed are additionally connected to one another by horizontally and diagonally extending coupling braces. The horizontal coupling brace connects the toggle levers in the region of the toggle link while the diagonal coupling brace connects a lower toggle lever arm to an upper toggle lever arm. The motor for raising and lowering the upper frame relative to the lower frame extends directly between these two frames such that the toggle levers and their coupling braces act as a parallel linkage of sorts.

Abstract: A control system for nursing care beds contains additional current and state (switch-on, switch-off) monitoring of the motors to sense potential thermal overload conditions. In an embodiment of the invention, if the control system detects that a motor has remained switched-on longer than a predetermined time and current is also flowing during this time, the control transitions to a blocking state to prevent thermal overloading of the motors.

Abstract: A hospital bed features a bed frame that is provided with a movable back rest and a movable head rest. A mechanism ensures that the head rest and the back rest can be moved by means of a single motor. Lifting of the back rest begins after the head rest has reached the maximum raised position.

Abstract: A hospital bed features a central control for operating the electric drives. To quickly lower the back section for reanimation purposes in case of an emergency, it is possible to select a special mode in which the motor for the back section is acted upon by a voltage that lies above the voltage acting upon the motor in the normal mode.

Abstract: A hospital bed having longitudinal rails, between which levers are supported. The levers are fixed on an axle tube that extends between the two longitudinal rails. The longitudinal rails are locally reinforced with respect to their wall thickness on the side situated adjacent to the axle tube by means of reinforcing plates welded thereto. A round rod extends through through-holes in the two longitudinal rails and the axle tube. For this purpose, the longitudinal rails are provided with through-holes that extend through the reinforcing plate.

Abstract: A rotating and sitting-up bed includes a height-adjustable base and a support frame, which is connected to the base by means of a rotating articulated element. The support frame can be rotated by 90 degrees relative to the vertical axis with the help of the rotating articulated element. The support frame is divided into a back section, a center section, a thigh section, and a lower-leg section. In the rotated position, the support frame can fold into a Z shape, wherein the back part projects upwards starting from the center section and the lower-leg part hangs downwards from the thigh part. In addition, a crank mechanism ensures that the thigh part is raised by a few cm at its front edge, which is adjacent to the back of the knee of the patient.

Abstract: The invention provides a hospital bed with two driving motors that are used in the vertically adjustable jack in order to increase the hoisting power of the bed so as to be able to lift heavy patients. The two driving motors are mounted so as to mechanically operate in parallel. In order to obtain a symmetric load distribution among the two motors, the motors are electrically connected in series and are supplied from a joint voltage source as a serial connection.

Abstract: A nursing bed is provided that has a height adjustable base, in which a rotary hinge is attached in a substantially countersunk arrangement. The rotary hinge connects the base to an intermediate frame on which the actual reclining frame is installed. In this way, a bed framework is obtained, which, after subtracting the height of support feet, has a very small structural height, so that in the lowest position, the distance from top edge of the mattress from the floor corresponds to the length of a lower leg, while simultaneously there is still space underneath the base.

Abstract: A rotating bed is provided that has a base with a mattress frame supported for rotation about a vertical axis. The mattress frame is divided into sections and can be converted into a chair-like configuration in one rotational position. In order to increase the stability of the arrangement in the chair position, at least one support leg is provided that either contacts the floor from the beginning or only makes contact with the floor when the stability limit without the support leg is exceeded.
