Acceleration compensating vehicular seat assembly
First Claim
1. A vehicular seat assembly (10) comprising:
- a seat cushion (12);
a seat back (14) pivotal about said seat cushion (12);
two bolsters (18,
20), with one bolster (18,
20) secured to each side of said seat back (14);
primary adjustment means (22) for adjusting each of said bolsters (18,
20) relative to said seat back (14) to provide support to an occupant, andsecondary adjustment means (24) disposed adjacent said primary adjustment means (22) for adjusting each of said bolsters (18,
20) to provide additional support to the occupant independent of said primary adjustment means (22) when said vehicular seat assembly (10) receives forces of lateral acceleration (36,

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).
