Abstract: An automobile seat is provided with a side impact air bag accommodated within a seat back. To permit prompt burst-out of the side impact air bag precisely at a predetermined position in a predetermined direction without the need for the arrangement of a member different in nature from a surface of the seat back on the surface of the seat back, an air bag module is arranged within a cushion pad of the seat back. Further, the cushion pad is provided, on a surface of a surrounding portion thereof with which the air bag is brought into contact upon spreading, with a guide member which increases breaking strength of the cushion pad and specifies the cushion pad to be broken at a break portion under inflating force of the air bag.

Abstract: The present invention is an improvement in seat construction for seating at least two passengers which includes a seat frame having front and back sides running the length of the frame and left and right sides running transverse of the frame, and is adapted to support at least two passenger seats. In particular, the present invention includes independent thigh support devices for each of the passengers, and a cushion member for each of the passengers which extend from the back of the seat frame and are arranged on each of the thigh support devices for simultaneous movement therewith and each of which have a perimeter dimension for supporting a passenger. Each of the thigh support devices, in turn, includes a thigh support frame pivotally fixed to the back of the seat frame for upward and downward rotation each thigh support frame formed so that it is substantially coextensive with the perimeter of each cushion member.
