Abstract

With the advent of self-driving cars, significant changes are expected in the posture of occupants, leaning back the seat or sleeping comfortably. In response to the consumers’ needs, automobile manufacturers have recently mounted ‘a Relax Seat’ on the front passenger seat, which can be moved comfortably by reclining the chair back. However, in the event of a vehicle accident, passengers seated in a relax seat are generally known to be more seriously injured than occupants sitting in a typical seat position. Accordingly, in this paper, comparative data on the SLED test is presented to investigate the influence of a relaxed seat posture on the risk of injury of the occupants. Moreover, a dual-depth passenger airbag was also introduced as a countermeasure in the design and evaluation process.
