Title: Guenter Spiegel: Vehicle Power-Drive and Safety-System Inventor.

Introduction

Guenter Spiegel is an inventor associated with Worms, Germany, and Robert Bosch. His work includes inventions for controlling vehicle power drives and improving the durability of automotive safety devices. He holds 6 patents.

Latest Patents

One of Spiegel’s latest patents, “Apparatus for Controlling the Power Drive of a Vehicle,” describes a mechanism that regulates a vehicle’s power-drive output. It uses an adjusting element, a coupler, stops, springs, and an intermittently operative coupling to delay or halt relative movement between components as the system shifts from an unregulated position to regulated positions.

His “Safety Device” patent addresses wear and shifting of the switch point in a device that monitors the relative positions of an adjuster element and a driver. The design uses two switch lugs on the adjuster element and a cam on a base, offering a simpler, more durable alternative to arrangements that rely on wipers lifting away from contact paths. The device is particularly suited to motor-vehicle power-control systems.
