What is claimed is: 1. A vehicle seat for operating advantageously at least in a crash, the vehicle seat comprising: a seat part structure; a seat cushion positioned on the seat part structure, wherein the seat cushion includes a recess; an antisubmarining ramp mounted for moving in the recess at least in response to, and at the latest at the beginning of, a crash, wherein the antisubmarining ramp comprises a hoop, the antisubmarining ramp being mounted for moving in the recess comprises the hoop being mounted for pivoting in the recess from a flat position into a raised position, and the hoop is biased toward the raised position; a retaining element for releasably securing the hoop in the flat position; and an actuator operative for at least indirectly securing the retaining element so that the retaining element secures the hoop in the flat position, and at least indirectly releasing the retaining element at the latest at the beginning of the crash, so that the retaining element releases the hoop, whereby the hoop pivots to the raised position. 2. The vehicle seat as claimed in claim 1, wherein: the seat cushion is flexible at least while the hoop is in the flat position, and the hoop stiffens the seat cushion while the hoop is in the raised position, so that the seat cushion is less flexible while the hoop is in the raised position than while the hoop is in the flat position. 3. The vehicle seat as claimed in claim 2, wherein the recess is present while the hoop is in the flat position. 4. The vehicle seat as claimed in claim 3, wherein the antisubmarining ramp hoop is in the recess while the hoop is in the flat position. 5. The vehicle seat as claimed in claim 1, wherein: the hoop extends at least partially around an at least substantially rectangular area; the hoop includes a longitudinal side; and the hoop being mounted for pivoting comprises the hoop being mounted for pivoting about the longitudinal side. 6. The vehicle seat as claimed in claim 1, wherein the actuator is an electrically operated actuator. 7. The vehicle seat as claimed in claim 1, wherein the hoop has at least one support which supports the hoop in the raised position. 8. The vehicle seat as claimed in claim 1, wherein the hoop has at least one stop which limits the movement of the hoop in the crash. 9. The vehicle seat as claimed in claim 1, wherein: the seat cushion is flexible at least while the hoop is in the flat position, and the hoop is in the recess and thereby stiffens the seat cushion while the hoop is in the raised position, so that the seat cushion is less flexible while the hoop is in the raised position than while the hoop is in the flat position. 10. The vehicle seat as claimed in claim 9, wherein: the hoop extends at least partially around an at least substantially rectangular area; the hoop includes a longitudinal side; and the hoop being mounted for being pivoted comprises the hoop being mounted for being pivoted about the longitudinal side. 11. A vehicle seat for operating advantageously at least in a crash, the vehicle seat comprising: a seat part structure; a seat cushion positioned on the seat part structure, wherein the seat cushion includes a recess; a structural component mounted for being moved from a first position to a second position; and a motion-imparting device operative (a) for moving the structural component from the first position to the second position, and (b) so that the structural component being moved from the first position to the second position comprises the structural component moving in, and relative to, the recess; and wherein the seat cushion is flexible at least while the structural component is in the first position, and wherein the structural component is in the recess and thereby stiffens the seat cushion while the structural component is in the second position, so that the seat cushion is less flexible while the structural component is in the second position than while the structural component is in the first position. 12. The vehicle seat as claimed in claim 11, wherein: the structural component comprises a hoop. 13. The vehicle seat as claimed in claim 11, wherein: the structural component is upright in the second position, and the structural component is more inclined in the first position than in the second position. 14. The vehicle seat as claimed in claim 13, wherein: the structural component comprises a hoop mounted for being pivoted in the recess from the first position to the second position, whereby the hoop is upright in the second position, and the hoop is more inclined in the first position than in the second position, and the hoop extends at least partially around an area. 15. The vehicle seat as claimed in claim 11, wherein: the recess is present while the structural component is in the first position, and the structural component is in the recess while the structural component is in the first position. 16. The vehicle seat as claimed in claim 11, wherein the motion-imparting device includes: at least one spring that biases the structural component toward the second position, a retaining element for releasably securing the structural component in the first position, and an actuator operative for: (a) at least indirectly securing the retaining element so that the retaining element secures the structural component in the first position, and (b) at least indirectly releasing the retaining element at the latest at the beginning of the crash, so that the retaining element releases the structural component, whereby the structural component moves to the second position. 17. The vehicle seat as claimed in claim 11, wherein the structural component has at least one support which supports the structural component in the raised position. 18. The vehicle seat as claimed in claim 11, wherein the structural component has at least one stop which limits the movement of the structural component in the crash. 19. The vehicle seat as claimed in claim 11, wherein the actuator is an electrically operated actuator. 20. The vehicle seat as claimed in claim 14, wherein the hoop extends at least partially around an at least substantially rectangular area.
