Publication number: 20220194243Abstract: A system for conductively charging a motor vehicle includes a charging device and a receiving device. The charging device has an electrical contacting unit and a lifting device operable, for axially moving the contacting unit between retracted and extended positions. The receiving device has a receiving chamber for receiving the contacting element inserted therein when the contacting element is moved to an extended position. The contacting unit has a cylindrical or truncated cone body and includes an electrical contact ring extending around a lateral surface of the body of the contacting element. The receiving device includes a radially position-able electrical contact element along the receiving chamber. When the contact element is in one radial position while the contacting unit is inserted into the receiving chamber the contact element electrically contacts the contact ring and mechanically fixes the contacting unit to the receiving device inside the receiving chamber.Type: ApplicationFiled: March 8, 2022Publication date: June 23, 2022Applicant: KOSTAL Automobil Elektrik GmbH & Co.

Patent number: 11299192Abstract: An operating arrangement for a vehicle includes a steering column retractable into and extendable out of a dashboard, a steering shaft that is retractable and extendable relative to the steering column, a steering wheel on an end of the steering shaft, and a steering column module arranged on the steering column between the steering wheel and the dashboard. The steering column module has a screen positioned behind the steering wheel. In a manual vehicle driving mode, the steering column is extended out of the dashboard to position the steering wheel and the steering column module away from the dashboard. In an automatic (or autonomous) vehicle mode, the steering column is retracted into the dashboard to position the steering column module against the dashboard and the steering shaft is retracted relative to the steering column to position the steering wheel adjacent the dashboard with the screen resting against the steering wheel.Type: GrantFiled: February 4, 2020Date of Patent: April 12, 2022Assignee: KOSTAL Automobil Elektrik GmbH & Co.

Patent number: 10207732Abstract: A steering column switch for a vehicle includes a switching lever that operates by pivoting in relation to a housing. The lever has a locking pin which assumes a stable position on a switching gate when the lever is not operated and is guided into an unstable position by operation of the lever. The switching gate guides the pin back into the stable position when operation of the lever ceases. A permanent magnet on a body of the lever is brought against an electromagnet on the housing by pivoting the lever into the unstable position. The lever is held in the unstable position by magnetic attraction between the magnets for a time in which a function associated with the lever being actuated into the unstable position is active. Afterwards, the electromagnet produces a counter magnetic field which interrupts the magnetic attraction so that the lever returns to the stable position.Type: GrantFiled: June 21, 2017Date of Patent: February 19, 2019Assignee: Leopold Kostal GmbH & Co.

Patent number: 10175066Abstract: A system for detecting the absolute rotational angle of a shaft rotatable more than one revolution includes a drive wheel connected to the shaft to rotate therewith. The drive wheel includes measurement sectors adjacent to one another in a circumferential direction. First and second driven wheels are engaged to the drive wheel. First and second sensors monitor rotational positions of the driven wheels to thereby detect an absolute rotational angle of the shaft. A third sensor monitors a relative angular position of the shaft in relation to a detected one of the measurement sectors to thereby detect the relative angular position of the shaft within one revolution of the shaft. The detected absolute rotational angle of the shaft is refined with the detected relative angular position of the shaft to thereby generate the absolute rotational angle of the shaft with more precision.Type: GrantFiled: December 28, 2011Date of Patent: January 8, 2019Assignee: Leopold Kostal GmbH & Co.

Patent number: 9988069Abstract: A steering column module includes a tubular jacket rotatably supporting a steering shaft, a switch module having a carrier including contact pressure surfaces, and a device for fastening the switch module to the tubular jacket. The device includes a clamp assembly between the tubular jacket and the switch module for exerting a clamping force on the tubular jacket. The clamp includes two half clamps each having two outwardly bent end flanges. The end flanges are axially movably accommodated in the carrier such that when the switch module is axially moved onto the tubular jacket the end flanges come into contact with axial end stops of the tubular jacket and the contact pressure surfaces of the carrier. The contact pressure surfaces exert forces on the end flanges as the switch module is axially moved onto the tubular jacket thus fastening the switch module to the tubular jacket with a clamping action.Type: GrantFiled: December 2, 2016Date of Patent: June 5, 2018Assignee: Leopold Kostal GmbH & Co.

Patent number: 6892602Abstract: A device for fastening a casing tube switch module to a casing tube of a steering wheel shaft when a steering wheel is mounted on the steering shaft. The device including a clamping element and a bearing. The clamping element is arranged coaxially between the casing tube and the switch module. The clamping element exerts a clamping force in a direction extending radially out from the steering shaft. The bearing rotationally decouples the steering wheel from the switch module. The bearing has a stator operable for transferring an axial motion of the steering wheel as the steering wheel is mounted on the steering shaft to the switch module such that the switch module moves axially with respect to the casing tube toward the clamping element and tensions the clamping element to apply the clamping force to fasten the switch module to the casing tube.Type: GrantFiled: December 23, 2002Date of Patent: May 17, 2005Assignee: Leopold Kostal GmbH & Co.
