Abstract: A fastening element for the installation and retention of an airbag at the body of a vehicle. The fastening device is equipped with an essentially flat first element component for the immediate fastening of the airbag to the body, and a second element component, basically stirrup shaped, for retaining the airbag between the two element components. The first element section and the second element section are combined to form one open and one closed end of the fastening device, with at least one of the two element components equipped with holding devices, providing for a secure pre-installation of the fastening device to the airbag.

Abstract: A vehicle chassis with a spring bracket supporting a helical spring braced between two spring plates. a region of a piston and a shock absorber tube is disposed within the helical spring. At least one of the spring plates is axially adjustable by a drive unit having a circular electric motor with a stator and a rotor, and a transmission having a threaded spindle and a threaded screw.

Abstract: A cutting device for plants, particularly lawnmower, is provided with at least one rotating blade (4a), which cooperates with a stationary counter-blade (13a). Here, at least the blade (4a) and/or the counter-blade (13a) is replaceably arranged in a respective blade support (3a, 14a).

Abstract: A steering system for mobile machines includes at least two hydraulic pumps; at least one steering gear connected to the at least two hydraulic pumps by hydraulic lines, the hydraulic lines being brought together to form a single feed line that is connected to the steering gear; at least one steering cylinder connected to the steering gear; and a return element being provided in each of the hydraulic lines connecting the respective pumps and at least one steering gear; wherein the at least two hydraulic pumps are variable displacement pumps that have pressure and feed current regulators, the regulators being adjustable to predetermined, variable load-sensing differential pressures.

Abstract: A method for the positionally correct placement of an operating equipment including a scoop tiltably disposed on a descending lift frame of a mobile machine including a wheeled loader. An automatic positioning device is actuated thereby activating a first magnetic valve utilizing a logical switching device cooperating with the automatic positioning device for switching a tilting piston of a control slide operatively connected to a tilting cylinder and to the lift frame into a position in which the control slide releases an oil flow to the tilting cylinder. The oil flow is delivered utilizing a controlled pump. A plurality of measurements is performed of a traveled distance of a piston rod of the tilting cylinder at predeterminable places during a continued extension of the piston rod thereby obtaining distance measurement values.

Abstract: A hydraulic system for machines provided with tools, particularly for wheel loaders, fork lifts or the like, including comprising at least one hydraulic accumulator, distributing valves, manometric switches and at least one nozzle for variably adapting the load pressure of the hydraulic accumulator to the load pressure of the lifting cylinder, wherein the load-damping system formed by the hydraulic accumulator is connected to the hydraulic lines responsible for lifting and lowering and extending between the hydraulic cylinder(s) and a control valve.

Abstract: In a hydraulically operated multiport valve having a floating position for connecting the cylinder chambers of a hydraulic piston-cylinder drive, a valve slide and a restraining piston associated with it are provided. By means of a respective dimensioning of the surface of both the part of the valve slide which can be charged with control pressure for attaining the floating position and of the restraining piston, a displacement of the restraining piston against the maximum pressure present in its control chamber becomes possible.

Abstract: In a lawnmower with a grass collection container, the level to which the container is filled is recognizable optically or acoustically. For this purpose, a sensor is arranged in the grass entry mouthpiece of the grass collection container to supply a quantitative or qualitative signal via an electronic evaluation circuit. The collection container is attached to the rear of the frame of the lawnmower.

Abstract: The invention relates to an electric-motor drive system for hand-guided tools, in particular for garden appliances but also for tools used at home such as drills and the like. A power source 12 which is portable or adapted to be fixed to the tool has a chargeable direct-current battery 14, the output of which is connected to a converter 16 which contains an electronic circuit which converts the DC voltage to a three-phase voltage. Via a three-phase line 22 a three-phase motor 18 is supplied and drives the tool 20 directly or via a coupling 28.

Abstract: A grader has a grader blade which can be pressed against the ground or lifted off it by means of piston-cylinder drives. To be able to vary the downard pressure of the grader blade in its float position, either the piston chamber or the piston ring chamber of each drive can be charged with a working fluid under pressure when the grader blade is in the float position, so that the corresponding drive exerts a force on the grader blade which increases or decreases the downward pressure of the grader blade on the ground. While still allowing the grader blue to follow the contour of the ground.

Abstract: A device for fastening handles, that consists of a connecting bushing (16) and an insert (18) that are attached to both the implement (86) and to the handle (10). The insert (18), which has a rectangular cross-section, is locked into the insertion opening in the connecting bushing when a catch (62) on a leaf spring (64) engages a hole (61) in the insert. The resulting positive lock can be disengaged by a push-button (48) or sliding sleeve. The push-button (48) rests against the end (74) of the leaf spring (64) and can be used to displace the catch (62) on the leaf spring from the hole (61). An axially elastic sleeve (84) between the end of the handle and the connecting piece (20) compensates for tolerances. The circular handle merges gradually into an oval or ellipse toward the connecting piece (20).

Abstract: A furrower having shares that are displaceable on a support pipe which is connected to a tool attachment socket by a swivel joint, that can be fastened in any position. The fastening place is effected by a clamping device which can be released against spring action by a manual knob or button. A clamping member within the head of the share is pressed by means of its clamping section against the support pipe. This clamping section can be released by pushing the manual knob inwards. Preferred places of attachment to the support pipe are defined by notches. Each notch can accommodate one share, the share being engaged with the notch by means of a notch pin.
