The invention relates to a frontal airbag for vehicle occupants, which has a contact wall (26) that faces the vehicle occupant when the frontal airbag is in the inflated state. Tensile elements (30, 30') are attached to the contact wall (26) within the airbag. In the inflated state of the frontal airbag (10), the tensile elements hold back the contact wall (26) in some sections so that the contactwall (26) forms a plurality of recesses (32) extending vertically from the point of view of the associated occupant in the installed and inflated state. The frontal airbag (10) can optionally assumea first completely inflated state and a second completely inflated state having a larger airbag volume than in the first state, a release device (40) being associated with at least some of the tensileelements (30, 30') and, when the release device is not activated, the frontal airbag (10) only entering the first state and, when the release device (40) is activated, the contact wall (26) bulging further toward the occupant in the region of the released tensile elements (30, 30') in order to enable the second state.

    一种用于车辆乘员的正面安全气囊用于车辆乘员的正面安全气囊具有在已充气的状态下面向车辆乘员的接触壁(26)。在安全气囊内部、在接触壁(26)上安置有牵拉机构(30,30’),该牵拉机构在正面安全气囊(10)已充气的状态下分段地拉住接触壁(26),从而使得接触壁(26)在已安装的、已充气的状态下形成从相关乘员的视角看竖直延伸的多个凹部(32)。任选地,正面安全气囊(10)可以具有已完全充气的第一状态和已完全充气的第二状态,该第二状态具有比在该第一状态下更大的安全气囊体积,其中给这些牵拉机构(30,30’)中的至少一些牵拉机构分配有一个释放装置(40),并且在释放装置未被启用时,正面安全气囊(10)仅达到第一状态;并且在释放装置(40)被启用时,接触壁(26)在所释放的牵拉机构(30,30’)的区域中进一步朝向乘员的方向鼓起,以使得能够实现第二状态。
