ABSTRACT:
A vehicular seat assembly (10) includes a pair of bolsters (18, 20) located on either side of the seat back (14). Each of the bolsters (18, 20) includes a primary adjustor (22) which moves the bolster (18, 20) to a position found to be comfortable by the occupant of the seat (10). Each of the bolsters (18, 20) further include a secondary adjustor (26) disposed adjacent the first adjustor (22). The two secondary adjustors (26) operate independently of each other and deploy when the seat assembly (10) senses a predetermined level of lateral acceleration forces (36 or 38). An accelerometer (34) senses the lateral acceleration (36, 38) and a control circuit (32) sends a signal to an activator (40) to deploy the one of the two secondary adjustors (26).
