Vehicle crash-safety seat

A vehicle crash-safety seat comprising:

• a seat bottom having a deploying air bag mounted in said seat bottom and adapted to shoot upward out of said seat bottom when said deploying air bag is activated during a vehicle collision of a predetermined severity;
• the inflated air bag is located over said seat bottom and only the lower part thereof is joined to said seat bottom,
• the inflating air bag being adapted to take up different positions and to change shape in response to an occupant's position in said seat to form, with a side portion thereof, an enlarged contact surface with said occupant's body, and to force said occupant's body to move into an occupant restraining position, thereby transmitting an upward motion of said inflating air bag to a backward motion of said occupant's body,
• whereby said backward motion of said occupant's body restrains a vehicle occupant from forward inertial movement during said vehicle collision.

• the inflated air bag is located over said seat bottom and only the lower portion thereof is connected to said seat bottom,
• the inflating air bag being adapted for changing position and form in response to an occupant's position in said seat for contacting with an occupant's body, and for forcing said occupant's body to move into an occupant restraining position, transmitting an upward motion of said inflating air bag to a backward motion of said occupant's body,
• whereby said backward motion of said occupant's body restrains a vehicle occupant from movement to the side where the vehicle is impacted during said crash.
