Patent number: 5560456Abstract: A hydraulic strut for a motor vehicle for providing a movement guiding and dampening function can generally have a cylinder, with a piston disposed in the cylinder to divide the cylinder into at least first and second chamber portions, with a piston rod extending from the piston out of the cylinder. The cylinder can be sealed at both ends, and can preferably be filled with hydraulic fluid. The piston can preferably define a flow connection between the two fluid chambers, and this flow connection can typically have some sort of valve arrangement therein for controlling flow of fluid between the first and second chamber portions.Type: GrantFiled: November 17, 1994Date of Patent: October 1, 1996Assignee: Stabilus GmbHInventors: Klaus Koch, Heinz-Josef Heinrichs

Patent number: 5468042Abstract: A compartment confining construction comprises an opening and a closure unit movably mounted on the compartment confining construction for movement between a closing position and a fully opened position with respect to the opening. A fluid-based positioning unit is connected to both the compartment confining construction and the closure unit, the fluid-based positioning unit having two working chambers interconnected by at least one flow path, a movement of the closure unit corresponding to a flow of fluid from one chamber to another through the at least one flow path. A fluid flow control device is provided for controlling the flow of fluid through the at least one flow path and thereby controlling the movement of the closure unit. The fluid flow control device is actuatable by an electric actuating device. The flow of liquid occurs in response to movement of the closure unit when the closure unit is moved by an external force.Type: GrantFiled: July 20, 1993Date of Patent: November 21, 1995Assignee: Stabilus GmbHInventors: Heinrich-Josef Heinrichs, Stephan Enders, Klaus Koch

Patent number: 5332260Abstract: A steering column of a motor vehicle is composed of two telescopically and torque transmittingly interengaging steering column tubes. These tubes are mounted in bearings. A steering wheel is allocated to a first steering column tube. The other steering column tube is connected with a steering gear box. A cylinder piston device is provided within at least one of the two steering column tubes. This cylinder piston device can be locked in a plurality of positions, such as to define a plurality of variable lengths of the steering column.Type: GrantFiled: December 8, 1992Date of Patent: July 26, 1994Assignee: Stabilus GmbHInventors: Heinz-Josef Heinrichs, Udo Wagner, Reiner Wendling

Patent number: 5090770Abstract: In the case of an item of seating furniture, particularly an office chair, comprising at least one seat adjusting device, for example for adjusting the height of the seat, with a spring element engaging the two parts of the seat which are to be adjusted in respect of each other, particularly a pressurized fluid filled spring, and with a locking device for the separable fixing of the two seat parts in whatever is the desired and selected adjusted position, the use of an electrical actuating element for the locking device is proposed, which is connected to a manually operable control means for the at least one seat adjustment, this allowing simplified operation with minimal structural expenditure.Type: GrantFiled: April 18, 1990Date of Patent: February 25, 1992Assignee: Stabilus GmbHInventors: Heinz-Josef Heinrichs, Stephan Enders, Udo Wagner, Alfred Dirksen

Patent number: 5074390Abstract: According to an illustrative example of the invention, a gas spring comprises a cylinder and a piston rod. The piston rod is axially movable with respect to the cylinder and has a fastening eye mounted on the outer end of the piston rod. A tubular protection member surrounds an end portion of the cylinder adjacent to the end of the cylinder which is passed by the piston rod. The other end of the protection tube surrounds a holding disk fixed to the piston rod adjacent to the fastening eye. The protection tube and the piston rod define an air space therebetween. The air space is substantially tight against a liquid treating agent, such as a lacquer. On the other hand, the air space is in air flow connection with the surrounding atmosphere so that in response to axial movement of the piston rod with respect to the cylinder, excesssive pressure within the air space is prevented.Type: GrantFiled: October 25, 1989Date of Patent: December 24, 1991Assignee: Stabilus GmbHInventors: Castor Fuhrmann, Alfred Klein, Heinz-Josef Heinrichs, Udo Wagner

Patent number: 4944498Abstract: In a gas spring the piston rod is guided through one end of a container. Adjacent to this one end two sealings are provided in axial direction one behind the other, namely an axially outer sealing and an axially inner sealing. A liquid chamber is defined between the axially outer sealing and the axially inner sealing. The axially inner sealing comprises a sealing ring of elastomeric material. This sealing ring comprises a radially outer root portion and a radially inner lip portion. The root portion engages an internal circumferential surface of the container tube. The lip portion engages an external circumferential surface of the piston rod. The axial dimension of the root portion is substantially larger than the axial dimension of the lip portion. The sealing ring may be deflected by pressure differences on both sides of the sealing ring such that a fluid exchange is possible between both axial sides of the sealing ring when the pressure difference exceeds a predetermined value.Type: GrantFiled: July 13, 1988Date of Patent: July 31, 1990Assignee: Stabilus GmbHInventors: Bernd Kortgen, Helmut Morgen, Heinz-Josef Heinrichs, Castor Fuhrmann, Herbert Freitag
