Title: The Innovations of David Prentkowski
Introduction
David Prentkowski is an accomplished inventor based in Sterling Heights, MI (US). He holds a total of 8 patents that showcase his expertise in automotive safety technologies. His innovative contributions have significantly impacted the design and functionality of seatbelt retractor systems.
Latest Patents
One of his latest patents is the "Low noise, debris tolerant retractor inertial sensor." This invention focuses on a seatbelt retractor inertial locking system for motor vehicle belt restraint systems. The system is designed to minimize the influence of contaminants that can cause unwanted locking of the retractor. A key feature of this invention is the positioning of a point contact between a ball mass and a locking lever. The inertial actuator forms the inertial ball mass nest surface, which has a vented construction that allows contaminants to escape, thereby reducing noise generated by contact between the ball mass and the nest surface.
Another notable patent is the "Mode detection switch assembly for self-locking dual-mode seat belt retractor." This dual-mode retractor is configured to switch between two modes: the Emergency Locking Retractor (ELR) mode and the Automatic Locking Retractor (ALR) mode. The switching mechanism relies on the relative movement between two parts of the retractor, utilizing a Hall effect sensor to detect changes in the magnetic field created by a permanent magnet.
