摘要

Provided is an active bolster for a vehicle occupant, the active bolster comprising a rear panel, an internal structure, and a front panel. The internal structure is disposed between the rear panel and the front panel, and the internal structure and rear panel together forming a hollow chamber in communication with an inflation device. The hollow chamber is expandable on activation of the inflation device. The internal structure has at least one expandable element such that upon pressurization of the hollow chamber by the inflation device, at least a portion of the at least one expandable element undergoes deformation to permit inflation of the hollow chamber, thereby displacing the rear panel rearwardly to an extended position.
