IMPROVEMENTS IN OR RELATING TO A VEHICLE SEAT

摘要

A vehicle seat (1) comprises a squab (2) and a back (3). The seat is associated with a roll-over sensor (11) which activates a pyrotechnic charge within a cylinder (12) to cause the seat (1) to move to an alternative configuration in which the head of the occupant of the seat is moved so that the clearance between the head of the occupant and the roof is increased. The head of the occupant is thus spaced further from the roof of the vehicle, since the roof of the vehicle may be depressed during a roll-over accident.
