Abstract

The system includes a seat which is mounted by a pivot 5 and an angular guide 6 so that it can drop downwardly in a collision. Submarining of the occupant is prevented by a base spine restraint 10 and an opposite shoulder strap (9, fig.2) in addition to the usual seat belt. The seat also has deployable head-rests 1 and an emergency detachment mechanism. The seat support element 4 can move longitudinally on rails on an inner frame member 12 which can itself move laterally on an outer frame member 13. These movements are damped in a collision by shock absorbers 15, 16, 17 which have hollow rubber bodies 15 and air passages. The safety system also includes a cable 25 connecting the seat mechanism to a latch which allows the steering wheel to retract in a collision. The dashboard (30, fig.13) on the driver's and front passenger's side is rotatable about a transverse axis to reveal knee-pads (29, fig.13) on its underside. The occupants' legs are guided towards the knee pads (29) by leg guides (31, fig.13). The air-bag 27 is transparent so that the driver's view is not obstructed.
