[0001] A restraint system for helping to protect an occupant (60) of a vehicle (20) includes a first inflator (74) for providing inflation fluid at a first fluid pressure and a second inflator (76) for providing inflation fluid at a second fluid pressure greater than the first fluid pressure. An airbag (70) includes a stored condition within a roof (32) and is inflatable to a deployed condition extending into a cabin (40) and aligned with a seat (50) for the occupant (60). The airbag (70) includes a first portion (98) defining a first chamber (100) fluidly connected to the first inflator (74)and a second portion (102) defining a second chamber (104) fluidly connected to the second inflator (76) and fluidly isolated from the first chamber (100). The first portion (98) moves relative to thesecond portion (102) in response to occupant (60) penetration into the airbag (70).

    一种用于帮助保护车辆(20)的乘员(60)的约束系统,该约束系统包括第一充气装置(74)和第二充气装置(76),该第一充气装置用于提供处于第一流体压力的充气流体,该第二充气装置用于提供处于比第一流体压力高的第二流体压力的充气流体。气囊(70)包括在车顶(32)内的储存状态、并且可充气到延伸到客厢(40)中并且与用于乘员(60)的座椅(50)对准的展开状态。气囊(70)包括第一部分(98)和第二部分(102),该第一部分限定流体地连接至第一充气装置(74)的第一腔室(100),该第二部分限定流体地连接至第二充气装置(76)并且与第一腔室(100)流体地隔离开的第二腔室(104)。第一部分(98)响应于乘员(60)陷入气囊(70)而相对于第二部分(102)移动。
