Abstract

In the field of collision safety, conspicuous progress has been made in recent years in occupant restraint devices. Collision avoidance technologies are also rapidly developing. Various proposals have been made for next-generation occupant restraint technologies which work in combination with collision avoidance systems. This paper discusses research on a next-generation seat belt system as a first step towards the realization of such a combination.

In this system a DC motor operates in parallel with a conventional pyrotechnic seat belt pretensioner. When a radar sensor system detects a forward obstacle, the DC motor operates to wind the seat belt and reduce slack before collision. This has made the seat belt pretensioner more effective in a front collision. This paper discusses the results of various tests on the motor-seat belt combination, and gives consideration to its effectiveness and shortcomings.
