The invention relates to a vehicle occupant restraint system having an airbag module (12) comprising a gas generator (18) and a front-acting airbag (16). The airbag (16) has a gas generator-side blowing end (46) and a first free end (56) which is located in a vehicle passenger compartment in the inflated state of the airbag (16). In a first period of time during deployment of the airbag (16), thefirst free end (56) is still connected to the airbag module (12) via the restraining band (74), and the restraining band (74) is released when a predetermined tensile force is reached. When the airbags (16) are gathered, the airbags (16) which are not inflated are unfolded as follows, namely the second free end (58) is furthest away from the blowing end (46), and the first outer wall section extends in the longitudinal direction of the airbag (16). The first free end (56) is located in the vicinity of the blowing end (46), the second outer wall section extends in the longitudinal direction ofthe airbag (16), and the third outer wall section of the airbag (16) is folded back onto itself at least in one section. The two side regions of the deployed airbag (16) are folded towards the centerand then the airbag (16) is wound from the second free end (58).
本发明涉及车辆乘员约束系统,其具有包括气体发生器(18)和在前面起作用的气囊(16)的气囊模块(12),气囊(16)具有气体发生器侧的吹气端部(46)以及第一自由端部(56),该第一自由端部在气囊(16)的充气状态中位于车辆客舱中。在气囊(16)展开期间的第一时段中第一自由端部(56)依然经由限制带(74)与气囊模块(12)连接,在达到事先确定的拉力时限制带(74)松开。在集拢气囊(16)时将未充气的气囊(16)如下地展开,即第二自由端部(58)最大限度地远离吹气端部(46)而第一外壁区段沿气囊(16)的纵向伸展,并且第一自由端部(56)位于吹气端部(46)附近而第二外壁区段沿气囊(16)的纵向伸展,气囊(16)的第三外壁区段至少在一个区段中折回到自身上。将展开的气囊(16)的两个侧边区域向着中心折叠,并且接着从第二自由端部(58)起卷绕气囊(16)。
