Introduction

Fredrik Wigström is a notable inventor based in Göteborg, Sweden. He has made significant contributions to the field of vehicle safety technology, holding 2 patents that enhance the functionality and safety of seat belt retractors.

Latest Patents

Wigström's latest patents include a "Belt retractor with a switchable force-limiting device." This innovative design features a vehicle seat belt retractor with a belt shaft and a coupled profile head that is lockable to a housing. The force-limiting device consists of at least two elements positioned between the profile head and the belt shaft. The free ends of these elements are interconnected by a connecting tube through a coupling element. This coupling element incorporates a hook-shaped spring element with a locking hook that engages with a locking groove on the connecting tube when the belt shaft rotates. At a predetermined angle of rotation, the bridging device releases the coupling element, allowing the locking hook to latch into the connecting tube's locking groove.

Another significant patent is the "Seat belt retractor for the safety belt of a motor vehicle." This design features a belt shaft that is rotatably mounted in a frame, along with a profile head that can be locked in relation to the frame. A load limiting device is situated between the profile head and the belt shaft, enabling the belt shaft to undergo a load-limited rotation in the belt webbing extraction direction when the profile head is locked. This innovation ensures that the load limiting level predetermined by the device is not exceeded, enhancing passenger safety.
