1. A vehicle seat arrangement, comprising:
- a seat body including a seat and a seat back at a rear of the seat; and
at least one displaceable seat component configured to be shifted in at least two degrees of freedom, from a refracted state to an actuated state in response to satisfaction of a condition regarding accelerations in a direction of a transverse vehicle axis;
wherein;
with respect to each of the at least one displaceable seat component;
in a retracted state, the respective displaceable seat component is situated entirely within the seat back; and
in an actuated state, the respective displaceable seat component is at least partly extended forward from an interior of the seat back, thereby forming a respective interior sidewall of the seat; and
a boundary of the seat body is defined by an opening of a recess into which the at least one displaceable seat component is retractable.

Abstract
A vehicle seat arrangement includes a seat body that includes a seat and a seat back at a rear of the seat. The vehicle seat arrangement also includes displaceable seat components which produce a lateral bracing as a function of accelerations in the direction of a transverse vehicle axis. The displaceable seat components are at least partly extendable in a necessitating situation. In a retracted state, the displaceable seat component is situated entirely within the seat back. In an actuated state, the displaceable seat component extends forward from an interior of the seat back, thereby forming an interior sidewall of the seat.

12. An operating method for a vehicle seat arrangement including at least one displaceable seat component integrated into a seat body, the seat body including a seat and a seat back at a rear of the seat, the method comprising:
-
detecting accelerations in a direction of a transverse vehicle axis; and responsive to the detected accelerations, shifting the at least one displaceable seat component in at least two degrees of freedom, from a retracted state to an actuated state; wherein; the shifting includes at least partly extending forward the at least one displaceable seat component from an interior of the seat back, by which extension each of the at least one displaceable seat component forms a respective interior sidewall of the seat; with respect to each of the at least one displaceable seat component, in the retracted state of the respective displaceable seat component, the respective displaceable seat component is situated entirely within the seat back; and a boundary of the seat back is defined by an opening of a recess into which the at least one displaceable seat component is retractable.

13. A vehicle seat comprising:
-
a seat body; displaceable seat components; and guides; wherein; each of the displaceable seat components is; integrated into an interior of the seat body; at least partly extendable from the interior of the seat body to be in an extended state, the extension being by movement of the respective seat component relative to, and in a direction that is parallel to a direction of extension of, a respective one of the guides; and configured to produce a lateral bracing as a function of accelerations in the direction of a transverse vehicle axis; and at least one of; the guides are curved and the extension of the displaceable seat components is in a curving direction along the curve of the guides; and the displaceable seat components are rigid both when positioned in the interior of the seat body and when in their extended state. - View Dependent Claims (14)
