Abstract

The experimental work reported in this paper consists of crash simulations to map the space swept by the head of a lap/sash belted occupant, in head-on and in a range of side impacts in which no invasion or loss of head space occurs. The work includes validation of a dummy and an investigation of the influence on head space of the angle of crash, of inertia reels in the sash straps, and of seat springing. The results provide evidence of the value of increasing head space so as to reduce the likelihood of head impact of otherwise well restrained occupants of passenger cars. Three current model cars are tested for availability of head space which is found to be inadequate, especially in front corner impacts on the occupant's side of the car, involving about 22 degree impact yaw.
